▼ Leaders remain perpetually connected to their work because of the rapid advancement of information technology. This research, using a qualitative approach, explored how increased connective technology is affecting school leaders with the central question: <i>How is hyperconnectivity experienced by school leaders?</i> Using personal interviews, the lived experiences of fifteen international middle and high school principals with one-to-one student-to-device programs were collected. Raw transcriptions of their experiences were analyzed using the descriptive phenomenological approach as outlined by Giorgi (2009). This approach allowed for the data to be reduced into a single narrative description shared by all participants indicating the essences of their lived experience as hyperconnected school leaders. This shared narrative highlighted complex and paradoxical experiences associated with how these school leaders interact with technology. Their experiences indicated that work-life balance for hyperconnected leaders required strong personal boundaries and skillful use of connective technologies. Examples of effective leader development of self and community highlighted, paradoxically, the need to unplug to effectively deploy connected technology within their leadership practice. Conversely, this study also showed how leaders can be controlled by connectivity. They associated their roles as responsible school leaders with perpetual connectivity; in consequence, they fused their work and home lives, experienced increased stress, and struggled with work overload. These results imply that international school principals are impacted by increased connectivity in different ways. Findings from this study indicate those leading hyperconnected schools must pay attention to how connectivity is affecting themselves and members of their school communities. Principals must protect themselves from the increasing demands upon their attention that constant connectivity presents in order to make mental room for the self-reflection and creativity needed to provide novel solutions and approaches towards their leadership work.

▼ This study explored the use of mathematics dialogue activities as an intervention for low achieving mathematics students. These activities consisted of short scripts that portrayed mathematics students working together to solve problems like those in their lessons. These were accompanied by discussion questions and mathematics problems intended to facilitate student discourse in small groups. This intervention strategy was based on the <i>Professional Standards for Teaching Mathematics,</i> which recommends the use of teaching methods that provide opportunities for student discourse. The purpose of the study was to help teachers and schools identify whether the use of discourse could provide an effective strategy to improve student learning and meet the requirements of the No Child Left Behind Act. A mixed methods case study design was used to provide a situated comparison of learning outcomes in two distinct instructional settings. Each of two teachers taught two prealgebra classes, one with and one without dialogue activities. Observations and classroom transcripts were used to describe the instructional settings and implementation, and to characterize classroom discourse in each setting. Quantitative methods were used to measure mathematics learning outcomes in terms of achievement and problem solving. In addition, a mathematics attitude survey and student interviews were used to address the potential influence of student attitudes and obtain feedback from students. Results included the development of mathematics dialogue activities as a model for introducing student discourse into diverse classroom settings. Classes using the dialogue activities were found to have more opportunities for student-led questions and explanations and displayed more indicators of student learning and attitudes than control group classes. Student attitudes also emerged as an important factor influencing implementation. Quantitative results indicated that students who participated in mathematics dialogue activities had greater gains in mathematics achievement in both settings, greater gains in problem solving skill in one setting, and positive effects on student attitudes concerning self-concept in both settings. The quantitative findings were not conclusive due to small sample sizes, but indicate that mathematics dialogue activities are a promising intervention strategy for low achieving students.

Ecological process and the blister rust epidemic| Cone production, cone predation, and seed dispersal in whitebark pine (Pinus albicaulis).

▼ Whitebark pine (<i>Pinus albicaulis</i>), a high elevation foundation species, is experiencing population declines throughout the northern part of its range. The introduced fungal pathogen, <i>Cronartium ribicola </i> (white pine blister rust), infects whitebark pine and kills cone-bearing branches and trees. Blister rust has spread nearly rangewide and damage and mortality are highest in the northwest US and southwest Canada. Mortality caused by mountain pine beetle (<i>Dendroctonus ponderosae</i>) population upsurges, and successional replacement and loss of regeneration opportunities from fire suppression, are also impacting some whitebark pine populations. Within this dissertation, I present three manuscripts that address the impact of whitebark pine's decline on species interactions and ecological processes within subalpine forests. Research was conducted in three ecosystems in the Rocky Mountains USA that are distinct in whitebark pine health conditions (rust infection and mortality) and abundance. In the first manuscript, I explore how the relationship between whitebark pine and Clark's Nutcracker (<i>Nucifraga columbiana</i>), its primary seed disperser, is being affected by whitebark's decline. Nutcrackers were less likely to use and disperse seeds from forests where cone production is below a threshold. In the second manuscript, I describe habitat use of whitebark pine forests by red squirrels (<i>Tamiasciurus hudsonicus</i>). Squirrel residency and impact of cone predation increased with decreasing whitebark pine abundance. The third manuscript focuses on the tree-level ecological process, predispersal cone survival, as a function of coarse scale whitebark pine abundance. Surviving trees in high mortality forests were found to have a lower rate and higher variability of cone survival, suggesting that the putative levels of rust-resistance in surviving trees of high mortality forests may not be passed on to future generations. At the ecosystem level, the Northern Divide had the highest levels of rust infection and tree mortality and lowest nutcracker interaction and regeneration levels; the Greater Yellowstone had the lowest infection and mortality levels and nutcrackers were present and dispersing seeds at all research sites in all years, while the Bitterroot Mountains were intermediate in these comparisons. These findings provide important components for developing a long-term strategy to conserve and restore whitebark pine ecosystems in the Rocky Mountains.

▼ The goals of this thesis were to improve the performance of silica polyamine composites by manipulating the surface structure and to understand the relationship between, polymer structure and ligand modification of the grafted polyamine. Improvements in silica polyamine composite performance resulted from modifying silica gel with methyltrichlorosilane (MTCS) substituted for a molar fraction of reagent chloropropyltrichlorosilane (CPTCS), which has been traditionally employed. MTCS does not possess a terminal chloride group thus preventing the subsequent attachment of a polyamine to this moiety. MTCS has a smaller molecular volume than CPTCS and as a consequence greater coverage of the silica gel surface by silanes was determined by elemental analysis and NMR. An increase in the fraction of amines not attached to the surface (free amines) allowed improved mass transfer kinetics and in some cases improvements in metal ion sorption capacities of the polymer modified materials. Further, MTCS is cheaper than CPTCS thus allowing a more economically sound synthesis. As a result of an increase in free amines, silica gel polyamine composites were modified with sodium chloroacetate and other metal selective ligands in higher yield, resulting in a material with substantially improved copper ion capacities. Silica polyamine composites have also been modified with a novel series of amino acid chelating ligands for the purpose of selective extraction of heavy metals from aqueous media. The presence of the functional groups was confirmed by 13C NMR and elemental analysis. The adsorption properties of modified composites have been determined for divalent and trivalent metal ions. Cycle testing was performed to measure longevity. Selective extraction and recovery of a single metal ion from media containing multiple metal ions has been demonstrated. The structure of the polyamine used has been shown to have a significant impact on the specific selectivity of modified silica polyamine composites even when modified with the same ligand. Potential areas of application have been tested and appear promising. These include an acid mine drainage polluted stream near Helena, MT, as well as synthetic high pressure leach laterite solutions.

Students' development in proof| A longitudinal study.

▼ Despite importance of teaching proof in any undergraduate mathematics program, many students have difficulties with proof (Dreyfus, 1999; Harel & Sowder, 2003; Selden & Selden, 2003; Weber, 2004). In this qualitative case study, nine undergraduate students were each interviewed once every two weeks over the course of an academic year. During each interview, the students were asked to complete, evaluate or discuss mathematical proofs. The results of these interviews were then analyzed using two different frameworks. The first focused on <i>proof type</i>, which refers to what kind of proof is created and how it came about. The second framework addressed identifying each student's <i>proof scheme</i>, which "constitutes ascertaining and persuading for that person" (Harel & Sowder, 1998). Using these structures as a guide, the question I sought to answer is: What, if any, identifiable paths do students go through while learning to prove? Unfortunately, the data from this study failed to demonstrate any identifiable path that was common to all participants. In fact, only a single student made clear progress as judged by the criteria laid out at the beginning of this study. Specifically, the way she attempted proofs changed which was reflected in a greater tendency to use a particular proof type as time passed: semantic. Of the other students, six entered the study with a fairly mature view of proof that remained unchanged and thus had little progress to make relative to the frameworks used in the study. These students were also generally successful with the proofs they attempted and were more likely to use semantic proofs. The remaining two students were generally less successful and used semantic proofs rarely. This seems to imply that as students become more comfortable with proof, they become inclined toward the semantic proof type and this coincides with becoming more successful with proof in general.

▼ This mixed method study examined the utilization of educational resources available to 44 Native American students. One-half initially attended a tribal college, and one-half Native American students who initially attended a non-tribal college. The qualitative process involved face-to-face interviews with the participants at the seven Montana tribal colleges. The resources included: mentoring programs, library services, financial aid assistance, distance learning programs, disability services, scholarships' applications process assistance, assistance in use of computers and the skills needed, tutors, student organizations, and academic counselors. The data from the first phase of the study were illustrated by the use of tables and descriptive narrative. The data were transcribed and subjected to data analyses as recommended by Strauss and Corbin (1990), Tesch (1990), and Creswell (1994). A grounded theory approach to produce a core category from the data yielded the following subcategories: (a) Barriers, (b) Success, (c) Challenges, (d) Clubs, (e) Family support, (f) Family member with college experience, and (g) Military experience. Further qualitative analyses of the data resulted in the following core category: "Native American Students Persisting in Higher Education." The second phase of the study involved a satisfaction survey of the educational resources utilized by each individual. The data from the satisfaction survey were ordinal data and the frequencies for the College's Services Satisfaction Survey were compiled. Tribal Colleges and Universities supported the students in acquiring financial aid and scholarships. All college experiences must include space and time for the re-creation of "family" in order for Native American students to persist and earn a baccalaureate year degree.

▼ Large herbivores are major drivers of community structure and function in many terrestrial systems. Through their direct effects on plants, large herbivores can influence the structure and complexity of habitats, the population abundance of animals that rely on those habitats, and the rates of ecosystem processes within those systems. These manifold impacts on systems are potentially magnifying, as removal of top predators and changes in land use have triggered large increases in large herbivore populations. Although increasing evidence suggests that large herbivores can critically shape the structure and function of the ecosystems they inhabit, few studies have detailed the direct and indirect effects of large herbivores on vegetation, animal populations, and ecosystem processes in the same system. Typically these varied impacts are studied in isolation and it is often unclear what the magnitude or sources of spatio-temporal variation in these effects might be. I used a large-scale replicated elk-exclusion experiment to determine the effects of elk on small mammal communities, plants, and ecosystem processes. I found that five years of elk exclusion led to noticeable changes in small mammal communities; some small mammals increased in the exclosure while others declined on controls. These changes were likely due to increasing habitat quality inside the fences and declining habitat quality outside. Elk browsing also decreased the recruitment of two dominant deciduous species and the quantity of litter of both of these species deposited on the forest floor during the peak in litterfall. Elk similarly reduced the cover of nitrogen fixing forb species, and the decomposition rates of both aspen and maple litter were more rapid inside the fences after 2 years of decomposition. These results indicate that elk are influencing the quantity and quality of litter inputs into this system as well as the decomposition environment. Finally, I found that mixtures of deciduous and evergreen litter influenced decomposition dynamics, the net mineralization of nitrogen, and plant growth. These results suggest that shifts in litter quantity and quality from browsing ungulates could have important indirect effects on plant growth. Overall, this work indicates that elk can have effects on multiple components of the community and ecosystem in only a short five year time period.

▼ This study sought to determine the relationship between participation in informal mathematics activities and the formal-to-informal beliefs of university teacher candidates in elementary education. Three classes of preservice teachers participated in the study through their enrollment in a content mathematics course for elementary education majors. Four informal mathematics activities were employed as part of the course requirements. Pre and post formal-to-informal beliefs about mathematics and mathematics instruction were measured using a Likert-scale beliefs assessment instrument used by Collier (1972) and Seaman et al. (2005). Changes in beliefs about mathematics and mathematics instruction were compared to a control group. Student reflection upon personal experience derived from participation in the activities was analyzed for formal and informal belief statements.

▼ According to recent studies, less than half of U.S. students perform at the proficient or advanced levels in mathematics by the time they reach grade 4 and the trend continues through high school. In order to improve instruction many districts have adopted scientifically based researched programs such as Response to Intervention (RTI), which allows for the examination of the effectiveness of the core curriculum that is being used in a school or classroom. In addition, RTI provides school administrators and teachers with educational tools to identify students who may be at-risk of failing and to inform teachers of supplemental instruction needed to build up skills that are identified as weak or lacking. Research on early mathematics skills indicates that skills performance at the kindergarten and first grade level may predict performance at later grade levels. Providing intervention early has been shown to have a positive effect on students' future mathematics success. This study investigated the long-term predictive validity of the AIMSweb measures for kindergarten through grade 2 and the Montana Comprehensive Assessment System (MontCAS). The kindergarten and grade 1 assessments included the Test of Early Numeracy which measures number sense skills that include Oral Counting, Number Identification, Quantity Discrimination, and Missing Number. The grade 1 and 2 Mathematics-Curriculum Based Measures assessed computational fluency. The scores on these K-2 assessments were analyzed to investigate correlations with the grade 3 MontCAS scores of the same students. The results indicated that Number Identification and Quantity Discrimination provided the most explained variance. Overall, the kindergarten scores were stronger indicators of grade 3 performance than the grade 1 scores. A sequential multiple regression model was also used to explore which of the TEN measures along with the hierarchy of tests from kindergarten through grade 2 had the greatest explained variance for the grade 3 MontCAS. The results showed that each test from kindergarten to grade 1 increased the predictability of the grade 3 MontCAS scores; however, the grade 2 scores did not contribute to the predictability of the grade 3 assessment. Overall, Oral Counting indicated the highest explained variance using this model.

▼ National assessments have led many to conclude that the level of ecological literacy among the general population in the United States is too low to enable effective social responses to current environmental challenges. However, the actual meaning of ecological literacy varies considerably between academic fields and has been a topic of intensive deliberation for several decades. Within the field of ecology in particular, a driving purpose behind this ongoing discussion has been to advance a complete, pedagogy-guiding, and broadly applicable framework for ecological literacy, allowing for the establishment of guidelines and tools for assessing educational achievement; yet, a widely accepted framework does not currently exist. <i>What is ecological literacy and how can it be achieved?</i> Through an extensive review of the literature, I traced the evolution of the related concepts of environmental literacy, ecological literacy, and ecoliteracy, and compared and contrasted the numerous proposed frameworks across multiple dimensions of affect, knowledge, skills, and behavior. In addition to characterizing the overall discourse, this analysis facilitated close examination of where we have been, where we are, and where we might be headed with respect to these vital conversations. To explore current perspectives on the topic, I analyzed the open-ended responses of more than 1,000 ecologists and other environmental scientists on the nature of ecological literacy and how it may be achieved. Factor analysis revealed the presence of six common dimensions underlying respondents' views of ecological literacy (cycles and webs, ecosystem services, negative human impacts, critical thinking/application, nature of ecological science, and biogeography) and five common dimensions for how to achieve it (education by mass media, formal/traditional education, financial incentive, participatory/interactive education, and communication/outreach by scientists). Based on these results, I proposed a framework for ecological literacy that, ideally, will provide guidance for the development of updated ecology curricula and assessment tools, a foundation for discussion of alignment between K-12 and higher education, and a mechanism for creating greater synergy between formal and informal learning environments. Further, to assess the impacts of innovative graduate programs designed to train ecologists in promoting ecological literacy, I analyzed pre- and post-fellowship surveys completed by participants in an ecologically focused K-12 outreach program at The University of Montana, as well as the broader impacts of a set of similar programs across the country. These highly beneficial programs are urgently needed to ensure that future leaders of the scientific enterprise are well-equipped with the tools to effectively communicate their science with diverse audiences well beyond their scientific peers. Indeed, ecologists and other natural and social scientists who study the environment have multiple roles to play in promoting a modern…

▼ Life experiences of young mothers of preschool aged children with Down syndrome were explored in this qualitative narrative study. Intensive interviews of four purposefully chosen young women were conducted. The findings of this study illustrate the impact of a preschool aged child with Down syndrome on the life of a young woman. A variety of themes were identified. The primary themes were the background of the woman, including her public school experience, learning of the diagnosis of Down syndrome, supports, the child's medical complications, learning to cope and the impact of that disability on their day-to-day lives. Child care and career were both impacted by the fact of the child's Down syndrome. Medical complications and behavior strongly affected day to day life. None of the participants recall positive inclusion experiences with other students with disabilities. The participants told of confronting bias in their immediate social circles and local communities. They also mentioned gathering support, and beginning to grow into advocates for their children. Expert knowledge and law are different from actual practices and widespread beliefs about the value of persons with disabilities in our society. The shared experiences provide insights into what it really is like to be a young mother of a child with Down syndrome. Suggestions for future research and lessons learned by the researcher were presented.

▼ Butte is a small town in southwest Montana that was profoundly shaped by over a century of mining and smelting activities. Today, Butte is a post-industrial city that is the focal point of America‘s largest Superfund site as well as the nation‘s largest National Historic District. There are two types of remediation occurring in Butte: environmental and cultural. Environmental remediation occurs throughout the city, most notably at the operable units of the Butte Superfund sites. This remediation does not restore the environment to its original state but instead reclaims it to a level of risk deemed acceptable by the EPA. Much like environmental remediation, community members practice acts of reclaiming history, landscape, and community. These are acts of cultural reclamation. To understand the current interrelationship between the environment, health, and culture in Butte, it is first necessary to understand the cultural foundations. Butte is a mining town that practices mining culture. A mining culture has several characteristics: physical and/or cultural isolation; pride in resilience, toughness, and craftsmanship; strong sense of community and kin networks; distrust of institutions, politics, and positions of power; historic pride and romanticizing the past; and gender division. These cultural values are at the core of Butte‘s culture and heritage. These values are a basis for historic preservationists who oppose environmental remediation and promote the preservation of the historic mining landscape. This is in sharp contrast to the environmental groups that promote environmental remediation and cite elevated risk levels and potential health effects in their reasoning. Debate about risk levels and the consequences of living in a toxic landscape do not provide answers regarding health issues, however. The community does not track disease rates and has never performed a longitudinal epidemiology study. By remaining unaware of disease rates, the community and those in positions of power are left with only opinions. As a remedy, this study set out to investigate mortality rates in Butte and compare them to the state of Montana and the United States. This study showed that the majority of the mortality rates in Butte are greater than the state of Montana and United States rates for all disease groups, and that mortality rates fluctuate over time but are consistently elevated. It also showed that mortality rates correlate with the target systems of concern. It did not show a clear reduction in mortality rates after remediation. Several diseases, such as neurological disease, did decrease after remediation, and this potentially correlates to the extensive lead abatement program in the city.

Management and life history consequences of hybridization between westslope cutthroat trout (Oncorhynchus clarkii lewisi) and rainbow trout (Oncorhynchus mykiss).

▼ The role of introductions of nonnative fishes in the decline of native fishes cannot be overstated. Westslope cutthroat trout (<i>Oncorhynchus clarkii lewisi,</i> WCT) are a salmonid native to the northern Rocky Mountains. These trout hybridize with rainbow trout (<i>O. mykiss,</i> RBT) where they are sympatric; however, in portions of the WCT range where RBT have been introduced, hybridization appears to spread rapidly and threatens continued existence of WCT. The conservation value of these hybridized populations is equivocal, and a better knowledge of the ecological, demographic, behavioral, and genetic consequences of hybridization is needed to better inform conservation strategies. I investigated three related questions: specifically, what landscape factors are associated with estimates of introgression; what are life history differences between WCT and hybrids; and what are tradeoffs in restoring migratory life history in populations threatened by hybridization? The riverscape context plays a substantial role in the distribution of hybrids, as estimates of introgression declined with increases in stream slope, elevation, and distance from a primary source of RBT, three correlated landscape variables. Spatial variation in patterns of hybridization suggests clarifying objectives for sampling and careful designs are necessary to adequately understand the status of populations. Variation in location may relate to some of the ecological differences, such as growth, among fish with different levels of introgression. In the Jocko River, hybrids with ancestry > 20% RBT demonstrated higher growth, earlier migration, increased egg size, and lower fecundity versus WCT. These lines of evidence demonstrate the importance of limiting further hybridization even in populations that already have low levels of hybridization. Given that many unaltered populations currently reside in isolated habitat fragments, I evaluated several demographic tradeoffs of restoring a migratory life history weighed against the risks of increased potential for hybridization from removing barriers or selectively passing migratory fish above the barriers using both matrix and genetic population models. Restoration of migratory life history substantially increases population viability; however, hybridization in above-barrier population increases predictably relative to hybridization status of below-barrier population, which may reduce viability if vital rates are reduced in hybrids. Hybridization creates a challenging set of management problems, but this research adds several important pieces to the puzzles to help develop and evaluate conservation strategies.

▼ The excitatory amino acid transporters (EAATs) play key roles in the regulation of CNS L-glutamate, especially related to synthesis, signal termination, synaptic spillover, and excitotoxic protection. Inhibitors available to delineate EAAT pharmacology and function are essentially limited to those that non-selectively block all EAATs or those that exhibit a substantial preference for EAAT2. Thus, it is difficult to selectively study the other subtypes, particularly EAAT1 and EAAT3. Structure activity studies on a series of β-substituted aspartate analogues identify L-β-benzyl-aspartate (L-β-BA) as among the first blockers that potently and preferentially inhibits the neuronal EAAT3 subtype. Kinetic analysis of 3H-Daspartate uptake into C17.2 cells expressing the hEAATs demonstrate that L-<i>threo</i>-β-BA is the more potent diastereomer, acts competitively, and exhibits a 10-fold preference for EAAT3 compared to EAAT1 and EAAT2. Electrophysiological recordings of EAAT-mediated currents in Xenopus oocytes identify L-β-BA as a non-substrate inhibitor. Analyzing L-<i>threo</i>-β-BA within the context of a novel EAAT2 pharmacophore model suggests: (1) a highly conserved positioning of the electrostatic carboxyl and amino groups, (2) nearby regions that accommodate select structural modifications (cyclopropyl rings, methyl groups, oxygen atoms), and (3) a unique region occupied by the benzyl moieties of L-TBOA, L-β-<i>threo</i>-BA and related analogs. It is plausible that the preference of L-β-<i>threo</i>-BA and L-TBOA for EAAT3 and EAAT2, respectively, could reside in the latter two pharmacophore regions.

▼ Poly(alkylene D-glucaramides) with higher molecular weights than previously reported were prepared through a multi-step process beginning with 1:1 alkylenediammonium D-glucarate salts. These salts set a precise stoichiometric equivalence between co-monomers, a necessary requirement for higher molecular weight condensation polymers. The salts were prepared by treating monopotassium D-glucarate with H+ form ion exchange resin to give D-glucaric acid, which was then reacted with a diamine. The glucarate portion of the salt was activated for polymerization through esterification in HCl/methanol. Polymerization was initiated by basification of the resulting mixture. The molecular weights of the polymers showed strong dependence on the base used in the basification step. Sodium methoxide was found superior to triethylamine for efficient deprotonation of the diammonium salt to yield higher molecular weight polyamides. The molecular weights of the resulting polymers were further increased through a second polymerization reaction in a dimethylsulfoxide and ethylene glycol solvent mixture which provides greater solubility for the polymers. The resulting poly(D-glucaramides) were found to serve as novel gel forming agents in aqueous solutions. Poly(hexamethylene D-glucaramide) formed rigid gels upon addition of water to a dimethylsulfoxide solution of the polyamide. By tailoring the water solubility profile of poly(alkylene D-glucaramides) through the use of two different diamines in the polymerization process, hydrogels were formed without dimethylsulfoxide and at low polymer concentrations (0.3-0.5%). The gelation of poly(aldaramides) is influenced by the aldaryl unit as polyamides from xylaric acid and galactaric acid have inferior gel forming ability compared to those from D-glucaric acid. The nitric acid oxidation of D-glucose to D-glucaric acid was also investigated with emphasis on isolation and purification of the organic acid oxidation products. Oxidation reactions were carried out in an automated reactor using three and four equivalents of nitric acid to D-glucose. Removal of residual nitric acid from the organic acid products was accomplished through vacuum distillation of the reaction mixture followed by filtration through either a diffusion dialysis unit or a nanofiltration system. While nanofiltration showed higher selectivity for separating nitrate, diffusion dialysis was capable of operating at higher feedstock concentration and at low pH.

▼ Females in nearly all sexually reproducing taxa mate with multiple males. In these species, male fitness is dependent on traits used during both the pre-copulatory processes influencing mate acquisition, as well as the post-copulatory processes influencing fertilization. However, few studies have simultaneously examined pre- and post-copulatory sexual selection within a particular species, and we therefore have little understanding of how these processes interact to determine male reproductive success. The objective of my study was to gain a more comprehensive understanding of the evolution of sexually selected traits by examining the interactions between pre- and post-copulatory processes in the tortoise beetle <i> Acromis sparsa</i>. I examined the relationship between traits involved in pre-copulatory strategies, such as secondary sexual characters, and traits involved in post-copulatory strategies, such as primary sexual characters and copulatory courtship. Primary and secondary sexual characters in <i>A. sparsa</i> were not correlated, indicating that males may be able to acquire and develop these traits independently of each other. On the other hand, copulatory courtship behaviors were negatively correlated with secondary sexual characters, suggesting that small males use courtship as a mechanism to compensate for decreased attractiveness to females, or to compensate for decreased access to females as a result of inferior fighting abilities. Thus, males may modulate the quality or intensity of their behaviors based on their pre-copulatory attributes. I also examined the relative importance of primary and secondary sexual characters as well as copulatory courtship on the reproductive success of <i> A. sparsa</i> males using natural insectary experiments, double mating experiments, and paternity analyses. I found that, in natural settings, males with larger testes mated with and fertilized more and larger females, and sired more offspring overall. In double mating experiments, testes mass and copulatory courtship influenced male reproductive success. However, the effects of copulatory courtship were dependent on mating order. Thus, even in species with exaggerated secondary sexual traits, such as <i>A. sparsa</i>, under certain conditions, it is post-copulatory sexual traits that make the largest contributions to male fitness. Moreover, the degree to which these traits contribute to reproductive success can vary with mating context.

▼ This descriptive study investigated student academic performance in skills-based word processing courses taught in two different scheduling formats at one small rural western United States university over the period of several years. One scheduling format followed a more traditional approach where courses were taken at the same time as at least one other course and in a time frame more resembling a typical semester. This distributed practice model, or cohort approach, required a prerequisite beginning level course or appropriate substitute course before enrolling in an advanced word processing course, thus spreading the instructional time over a longer timeframe. The other scheduling format allowed students to take only one course at a time, thus a massed practice model, in a compressed time format that presented the contents of the entire course in 18 instructional days. Student academic performance was measured by a subset of equivalent posttest questions that were common to both scheduling formats. Retention performance during the cohort approach was measured by a subset of equivalent questions common to the beginning and advanced cohort courses. The entire population of word processing students at this university was studied and thus there is no generalizability from this study to another population. Participants self-selected into groups by enrolling in course sections. Simple means were used to compute descriptive and comparative statistics. The distributed practice cohort group out-performed the massed practice group by an experimentally important five percent on the posttest. Results from the retention portion of the study indicate additional research is needed.

▼ Effective conservation planning in the face of rapid land use change requires knowledge of which habitats are selected at landscape scales, where those habitats are located, and how species ultimately respond to anthropogenic disturbance. I assessed sage-grouse (<i>Centrocercus urophasianus</i>) large scale habitat ecology and response to energy development in the winter and nesting seasons using radio-marked individuals in the Powder River Basin, Montana and Wyoming, USA. Landscape scale percent sagebrush (<i>Artemisia spp.</i>) cover at 4-km2 was the strongest predictor of use by sage-grouse in winter. After controlling for vegetation and topography, the addition the density of coal-bed natural gas wells within 4 km2 improved model fit (AIC -6.66, <i>wi</i> = 0.965) and indicated that sage-grouse avoided energy development. Nesting analyses showed that landscape context must be considered in addition to local scale habitat features (<i>wi</i> = 0.96). Findings provide managers a hierarchical filter in which to manage breeding habitats. Twice the amount of nesting habitat at 3, 5 and 10-km scales surrounded active leks versus random locations. Spatially explicit nesting and wintering models predicted independent sage-grouse locations (validation R2 ≥ 0.98). I incorporated knowledge of energy impacts into a study design that tested for threshold responses at regional scales analyzing 1,344 leks in Wyoming from 1997-2007. Potential impacts were indiscernible at 1-12 wells within 32.2 km2 of a lek (∼1 well/640 ac). At higher wells densities a time-lag showed higher rates of lek inactivity and steeper declines in bird abundance 4 years after than immediately following development. I spatially prioritized core areas for breeding sage-grouse across Wyoming, Montana, Colorado, Utah and the Dakotas and assessed risk of future energy development. Findings showed that bird abundance varies by state, core areas contain a disproportionately large segment of the breeding population and that risk of development within core areas varies regionally. My analyses document behavioral and demographic responses to energy development, offer new insights into large scale ecology of greater sage-grouse and provide resource managers with practical tools to guide conservation.

▼ Organisms have different life history stages where their energetic priorities differ between the goals of growth, survival, and reproduction. Behavioral decisions within stages and in the transition between stages have significant repercussions for future success so the timing of behaviors is extremely important. In this dissertation, I ask: How do intrinsic and extrinsic factors control the timing of behavioral decisions during tradeoffs within life history stages (the tradeoff between reproduction and self maintenance in breeding adults), and transitions between life history stages (the transition to independence in young animals) in a pelagic seabird, the Laysan Albatross (<i>Phoebastria immutabilis</i>). First, I ask how physiology changes during incubation fasts over the entire 2-month incubation period. I found total corticosterone (CORT) increased both within individual incubation shifts and over the season as body mass declined. Corticosteroid binding globulin (CBG) significantly increased as individual body condition declined. Though CORT secretion steadily increased during long, repeated fasts in this species, CBG may also rise to protect the reproductive attempt from the inhibitory effects of CORT on parental behavior. Next, I explore individual variation in parental provisioning trips during the chick rearing period. I found that surprisingly, adults expected to invest highly in their current reproductive effort, performed a pattern of foraging trips thought to be the strategy of adults investing in self-maintenance. This challenges previous work from the southern hemisphere and indicates that environmental differences in the northern hemisphere may change the distribution or predictability of ocean resources such that the benefit of different types of trips may not be fixed. Finally, I investigate morphology and physiology in chicks approaching fledging. I suggest that there are two primary factors contributing to the timing of fledging in Laysan Albatrosses: wing disc loading and plasma free CORT levels. After chicks reach a critical developmental threshold, they may fledge if food delivery is inadequate or stay if it is plentiful. When food delivery is unpredictable and chicks lose energetic stores, free CORT levels may fine-tune the timing of fledging: chicks with high free CORT when they reached the fledging threshold fledged sooner than chicks with low CORT levels.

▼ I applied a satellite remote sensing based production efficiency model (PEM) using an integrated AVHRR and MODIS FPAR/LAI time series with a regionally corrected NCEP/NCAR reanalysis surface meteorology and NASA/GEWEX shortwave solar radiation inputs to assess annual terrestrial net primary productivity (NPP) for the pan-Arctic basin and Alaska from 1983 to 2005. I developed a satellite remote sensing based evapotranspiration (ET) algorithm using GIMMS NDVI with the above meteorology inputs to assess spatial patterns and temporal trends in ET over the pan-Arctic region. I then analyzed associated changes in the regional water balance defined as the difference between precipitation (P) and ET. I finally analyzed the effects of regional climate oscillations on vegetation productivity and the regional water balance. The results show that low temperature constraints on Boreal-Arctic NPP are decreasing by 0.43% per year (<i>P</i> < 0.001), whereas a positive trend in vegetation moisture constraints of 0.49% per year (<i> P</i> = 0.04) are offsetting the potential benefits of longer growing seasons and contributing to recent drought related disturbances in NPP. The PEM simulations of NPP seasonality, annual anomalies and trends are similar to stand inventory network measurements of boreal aspen stem growth (<i> r</i> = 0.56; <i>P</i> = 0.007) and atmospheric CO2 measurement based estimates of the timing of growing season onset (<i> r</i> = 0.78; <i>P</i> < 0.001). The simulated monthly ET results agree well (RMSE=8.3 mm month-1; R2=0.89) with tower measurements for regionally dominant land cover types. Generally positive trends in ET, precipitation and available river discharge measurements imply that the pan-Arctic terrestrial water cycle is intensifying. Increasing water deficits occurred in some boreal and temperate grassland regions, which agree with regional drought records and recent satellite observations of vegetation browning and productivity decreases. Climate oscillations including Arctic Oscillation and Pacific Decadal Oscillation influence NPP by regulating seasonal patterns of low temperature and moisture constraints to photosynthesis. The pan-Arctic water balance is changing in complex ways in response to climate change and variability, with direct linkages to terrestrial carbon and energy cycles. Consequently, drought induced NPP decreases may become more frequent and widespread, though the occurrence and severity of drought events will depend on future water cycle patterns.

▼ Due to the pressures and expectations for current and future principals to create safe and welcoming schools with high student achievement, a better of understanding of the relationship between Positive Behavior Supports (PBS), student achievement, severe problem behavior, and administrative stress was needed. This study investigated the relationship between these four factors, as measured through the Effective Behavior Supports Survey (Sugai, Horner, & Todd, 2003), Adequate Yearly Progress (AYP) (OPI, 2008), suspension/expulsion rates, the Administrative Stress Index (Gmelch & Swent, 1977), and respondent characteristics. All practicing elementary and secondary principals in Montana were invited to participate in this survey via online and mailed invitations; 232 principals responded out of 516 possible. Respondent characteristics indicated the sampling was an accurate representation of Montana principals. The resulting data were analyzed for correlations between the four main factors and their components. Variables meeting screening tests were subjected to discriminant function analysis. All combinations of variables including PBS and administrative stress levels were also subjected to further statistical analysis. Results indicated that Montana principals reported low to moderate levels of administrative stress and high levels of PBS components present. Participants indicated AYP status in all areas, as well as levels of severe problem behavior, as similar to state averages. No experimentally important relationships were found between district size, school grade level, school poverty level, previous training/education, or years of experience, nor were these variables found to have an experimentally important relationship with any other study variables. No experimentally important relationship was found between PBS rates, student achievement, severe problem behavior, or administrative stress. However, an experimentally important relationship was found between level of PBS-related training and rates of PBS components present; statistical analysis showed a consistent pattern of participants with the highest levels of PBS-related training reporting the highest rates of PBS components present. In addition, though the results did not meet tests of importance, there was a consistent pattern of low administrative stress levels associated with higher rates of PBS components present. Results are discussed in terms of implications for practice and future research.

▼ The wolf recolonized part of its former habitat in the South-Western Alps through dispersal from the Apennines beginning in the late 1990s. Prioritization of conservation actions and effective management of this species relies on estimates of wolf population trend, survival rates, occupancy parameters, and on the development of a spatially explicit population model. These estimates were lacking in Italy and Western Europe, and accurate and cost effective methods to assess these parameters have not been implemented. I used genetic capture-mark-recapture techniques with long-term fecal genotyping data and applied open-population models to estimate survival rates and assess trend in abundance of wolves in the Western Alps. The wolf population in the study area increased from 21 ± 10 wolves in 1999 to 47 ± 11 wolves in late winter 2005. Young wolves (< 1 year old) had lower apparent annual survival rates (0.24 ± 0.06) than adult wolves (0.82 ± 0.04). I applied an unconditional multi-season occupancy model to estimate wolf occupancy dynamics. Human disturbance (β = -5.553, SE = 2.186) and rock-area cover (β = -4.129, SE = 1.392) had negative effects on occupancy, while the presence of red deer (β = 0.694, SE = 0.306) and forested-area cover (β = 0.596, SE = 0.458) had positive effects. The wolf recolonization process was characterized by a Markovian change in occupancy and the sites were not in an equilibrium state. This is typical of an expanding population. The habitat suitability map produced from the occupancy analyses was fundamental for the development of a spatially explicit, individual-based model which allowed a full analysis of this complex spatial and temporal wolf recolonization of the Italian Alps. I predicted wolf pack numbers, along with pack locations and wolf population size, over the Italian Alps in 2013, 2018, and 2023. I predicted 25 packs (95%CI – 19, 32) in 2013, 36 (95%CI – 23, 47) in 2018, and 49 (95%CI – 29, 68) in 2023. The South-Western Alps were the main source for wolves repopulating the Alps from 1999-2008. This main source area will likely be shifted to the Cozie Alps after 2008. In the next 15 years, the primary source for wolves repopulating the Alps will likely move to the north which could allow the full recolonization of the Eastern part of the Alps.

▼ Beginning in the late 1980s herpetologists began to realize that amphibians around the world had undergone, and were continuing to undergo, declines, extirpations, and extinctions. In most cases, detections of declines and determinations of the underlying causes has been hampered by a lack of available baseline information on distribution and status. This project was a cooperative effort to address these data deficiencies for amphibians and reptiles in Montana. Watersheds with greater than 30 percent federal or state land ownership were randomly selected for survey in each of 11 geographic strata. Visual encounter and dipnet surveys of all standing water bodies on public lands within these watersheds yielded watershed and site occupancy estimates as a measure of status. Occupancy estimates from this first-ever state-wide base level assessment can be more validly used for future comparisons with future status assessment, provided additional support for declines in Western Toad (<i>Bufo boreas</i>) and Northern Leopard Frog (<i>Rana pipiens</i>) populations in western Montana, and identified a variety of conservation issues of concern that can be addressed through management actions (e.g., clear evidence for negative impacts of fish and importance of maintaining natural disturbance regimes such as flooding, beaver, and fire). The information gathered during field inventories was combined with other existing information and used in maximum entropy modeling to predict state-wide distribution and habitat suitability for all of Montana's amphibians and reptiles. These models out performed GAP analysis models by simultaneously reducing the area predicted and omission error rates. Among other things, models identified scale dependent responses to environmental variables, potentially isolated populations in need of conservation efforts, and areas that are critical for maintaining landscape connectivity. In conjunction with field inventories, a state-wide assessment of the distribution of the pathogenic chytrid fungus (<i>Batrachochytrium dendrobatidis </i>) (Bd) was undertaken using PCR-based detection in skin swabs or tissue samples. Bd was found across Montana in 6 of the 9 species tested at a variety of elevations, habitats, and distances from human activities. The widespread presence of Bd highlights the need for additional studies and measures to prevent the spread of Bd and other novel pathogens.

▼ The purpose of this qualitative interpretive biographical study was to enhance our understanding of leadership by exploring the life of Bai Fangli through the lens of Confucian virtues. This study followed Denzin's (1989a) qualitative design of interpretive biography by exploring Bai's epiphanies to offer multiple perspectives on the significance of the epiphanies and their impact on Bai's life and his influence as a modern Chinese leader. This study was guided by the central question: What is the essence of the life and leadership of Bai Fangli as explored through the lens of Confucian virtues? In order to answer this study's central question, Denzin's data analysis procedures were applied for this study. Incorporating Denzin's data analysis procedures, this study applied three phases of data analysis: (a) document analysis, (b) interview analysis, and (c) combined the analysis of the documents and interviews. Data from documents were gathered from 91 online newspaper articles, 43 photographs, and 8 videoclips. Interview data were gathered during open-ended interviews with 12 purposefully selected participants. An internet-based audio video system, emails, and phone were utilized in this study. Four themes and seven sub virtue themes were combined from these documents and interviews. The lens of Confucian virtues was articulated based on seven sub virtue themes and how they are aligned with the literature review. Bai Fangli's interpretive biography was then reconstructed and the major themes that have shaped his life were identified. This study enhances our understanding of leadership by articulating Ren Leadership, a universal leadership. Since Bai's actions demonstrated both Eastern virtues of benevolence and great love [<i>ren ai</i>], righteousness [<i>yi</i>], rituals [<i>li</i>], wisdom [<i>zhi </i>], trustworthiness [<i>xin</i>], fortitude [<i>yong </i>], and frugality [<i>jian</i>] and Western virtues of prudence, justice, fortitude, and temperance, the second finding recognized that moral leadership is applicable to both Eastern and Western world views. The third finding describes an example of a moral leader in China who blended both Eastern and Western virtues. Finally, this study revealed the feasibility of the return of the traditional Confucian virtues in contemporary China.

▼ Frank B. Wynn was a leader in the first decades of the 20th Century. In the process of establishing timeless leadership standards for reconstructing his biography, it became apparent that no such standard existed, owing to more than 300 definitions of leadership at the end of the 20th century. The central research question asked what elements of leadership are historically and logically independent of context, and if those elements can be illuminated in a specific example of a leader examined from holistic criteria? The study consisted of an etymology of leadership terms, an exploration of Aristotle's Nicomachean Ethics, Politics, and Categories, an examination of the criteria for accurate definition, and finally a reconstructed biography of Dr. Frank B.Wynn

▼ Current domestic and international comparative studies of student achievement in science are demonstrating that the U.S. needs to improve science education if it wants to remain competitive in the global economy. One of the causes of the poor performance of U.S. science education is the lack of students who have developed the formal thinking skills that are necessary to obtain scientific literacy. Previous studies have demonstrated that formal thinking skills can be taught to adolescents, however only 25% of incoming college freshman have these necessary skills. There is some evidence that adolescence (girls aged 11-13, boys aged 12-14) is a critical period where students must learn formal thinking skills, similar to the critical period that exists for young children learning languages. It is not known whether it is more difficult for students to learn formal thinking skills either prior to or following adolescence. The purpose of this quantitative case study is to determine whether adolescence is a critical period for students to learn formal thinking skills. The study also investigates whether a formal thinking skills focused program can improve students' intelligence. In this study 32 students who had not developed any formal thinking skills, ranging in age from 10-16, underwent an intensive four-week, inquiry-based, formal thinking skill intervention program that focused on two formal thinking skills: (1) the ability to control and exclude variables; and (2) the ability to manipulate ratios and proportionalities. The students undergoing the training were matched with control students by age, gender, formal thinking skill ability, and intelligence. The control group attended their traditional science course during the intervention periods. The results of the study showed that the intervention program was successful in developing students' formal thinking skills. The pre-adolescents (males, age 10-11, females, age 10) were unable to learn formal thinking skills. The data indicated that there is not a significant difference between adolescents and post-adolescents (up to 16-years-old) ability to learn formal thinking skills. Both groups (adolescent and post-adolescent) showed improvement in their formal thinking skill ability after the intervention. The intervention also demonstrated evidence of improving students' intelligence scores.

▼ TCDD (dioxin) causes immunosuppression via activation of the Aryl hydrocarbon receptor (AhR). Dendritic cells (DCs), the professional antigen-presenting cells in the immune system, are adversely affected by TCDD. However, limited information exists regarding the effects of AhR activation on DCs. We evaluated the consequences of AhR activation by TCDD on both steady-state and inflammatory DCs using in vivo and in vitro approaches, respectively. We hypothesized that AhR activation alters DC homeostasis and differentiation leading to generation of immunosuppression. C57Bl/6 mice gavaged with an immunosuppressive dose of TCDD (15 &mgr;g/kg) displayed decreased frequency and number of splenic CD11chigh DCs on day 7. Moreover, TCDD induced a selective loss of the CD11chighCD8&agr;-33D1+ splenic DCs subset, specialized at activating CD4+ T cells, but not the regulatory CD11chighCD8&agr;+DEC205+ splenic DCs. Additionally, TCDD increased the expression of CD86 and CD54, while decreasing the frequency of CD11a and MHC II on the splenic CD11c high DCs. Although TCDD did not alter the number and frequency of CD11clow splenic DCs, it decreased their MHC II and CD11a expression. The loss of CD11chigh DC was independent of an apoptotic event but involved a CCR7-mediated migratory event. Popliteal and brachial lymph node (PBLNs) CD11c+ cells displayed elevated levels of MHC II and CD40, but not DC loss following TCDD exposure. To examine the effects of TCDD on inflammatory DCs, BMDCs were generated in the presence of GM-CSF and vehicle or TCDD. TCDD decreased CD11c expression but increased MHC II, CD86 and CD25 expression on these BMDCs. These effects were AhR-dependent but not exclusively DRE-mediated. Additionally, TCDD modulated antigen uptake and increased LPS- and CpG-induced IL-6 and TNF-&agr; levels but decreased nitric oxide production by the BMDCs. TCDD downregulated LPS- and CpG-induced p65 levels and induced a trend towards upregulation of RelB levels in BMDCs. Despite the induction of suppressive mediators IDO1, IDO2 and TGFβ3, TCDD-BMDCs failed to suppress T cell activation in vivo or induce the generation of adaptive T-regs in vitro. Collectively, our data suggest that AhR activation disrupts DC homeostasis, modulates DC differentiation, TLR responsiveness and induces a regulatory phenotype, effects that may underlie TCDD-induced immunosuppression.

▼ The prevalence of asthma has markedly increased in recent decades. Asthma affects approximately ten percent of the population of the United States, and is the leading cause of childhood hospitalization. This epidemic has been attributed to air pollution, childhood immunizations and a more sanitary living environment. Allergic asthma is clinically characterized by airway hyperreactivity (AHR), increased mucus production and airway remodeling. On the cellular level, pulmonary eosinophilic infiltration and augmented levels of serum IgE arise as a consequence of a CD4+ Th2 cell response in the airway following exposure to allergen. It has been proposed that the chronic inflammation and associated airway events evident in this disease stem from a failure to regulate the underlying immune response. How these events are regulated in the healthy lung is yet unclear. In studies to investigate the mechanisms underlying such regulation we found that firstly, co-transfer of expanded natural CD4+ CD25+ Foxp3+ regulatory T cells (nTregs) mediated regulation of CD4+ Th17 effector cells as exemplified by diminished levels of IL-17 and decreased neutrophilic infiltration in the airways. In contrast, co-transfer of nTregs did not attenuate the lung inflammation elicited by CD4+ Th2 or Th1 polarized cells. Interestingly, using the C129.IL4GFP mice we found that nTregs have the capacity to inhibit IL-4 production and Th2 differentiation in vitro. Secondly, mice with genetically disrupted receptors (IP-/-) for the lipid-mediator prostacyclin (PGI2), demonstrated increased airway inflammation, eosinophilic infiltration and airway hyperreactivity following immunization and repeated aerosol challenge with ovalbumin. Moreover these mice displayed reduced serum immunoglobulin levels. In summary, nTregs serve a specific function in controlling Th17 cell effector functions, but not Th1 or Th2 inflammation. Additionally, PGI2-IP signaling is an important pathway for inhibiting allergic pulmonary inflammation by controlling CD4+ Th2 cell effector functions.

▼ Disturbance-dependent species regularly colonize ephemeral habitat patches. In this research, I used patterns of genetic variation to estimate the dispersal dynamics of black-backed woodpeckers (<i>Picoides arcticus</i>), a fire specialist, and compared these patterns to hairy woodpeckers (<i>Picoides villosus</i>), a generalist. I then examined how frequent colonization of ephemeral habitat patches versus stable migration among static habitat patches shapes the genetic structure of species. I examined patterns of genetic variation in mtDNA and microsatellites in both black-backed and hairy woodpeckers to determine large-scale spatial structure. Black-backed woodpeckers have high genetic connectivity across the boreal forest and lower genetic connectivity among sites separated by large gaps in forested habitat. Across the boreal forest, hairy woodpeckers have low genetic differentiation in mtDNA that lacks spatial structure, but moderate genetic differentiation in an isolation by distance pattern in microsatellite data. These results suggest that large gaps in forest act as a movement barrier to black-backed woodpeckers; movement patterns of hairy woodpeckers are primarily driven by geographic distance as opposed to landscape composition. Once I understood the primary mechanisms driving large-scale patterns, I determined the fine-scale spatial structure in both species. Black-backed woodpeckers apparently disperse twice as far as hairy woodpeckers based on patterns of fine-scale geneticstructure. Female black-backed woodpeckers have limited dispersal, with long-distance dispersal being male-biased. A weak pattern of female-biased dispersal was observed in hairy woodpeckers. I used simulations to evaluate how effective population size and dispersal distance interact with two models of dispersal, frequent colonization of ephemeral patches and stable migration, to shape large-scale genetic structure. Frequent colonization of ephemeral habitats resulted in lower spatial structure and higher genetic differentiation among patches in comparison to stable migration. Low genetic differentiation with little spatial structure occurred at an intermediate dispersal distance in the frequent colonization model, the pattern observed in black-backed woodpeckers. Stable migration with short dispersal distance results in isolation by distance, the pattern observed in hairy woodpeckers. Disturbance-dependent species have evolved with a natural mosaic of shifting habitat patches. As anthropogenic disturbance increasingly changes this mosaic, ecologists need to consider how this shift may affect connectivity for disturbance-dependent species.

▼ Conserving wide ranging, endangered species is challenging, and managers often lack information on movement and social dynamics. Wild dogs, <i>Lycaon pictus,</i> are large, wide-ranging carnivores and one of the most endangered animals in Africa. Unlike other large carnivores, wild dogs do not vocalize as a form of territorial advertisement so to explore mechanisms of communication and movement behaviors, I radio collared and observed a population of wild dogs in northern Botswana, to collect fine-scaled, contemporaneous movement data on neighboring packs of wild dogs, and collected scent marks from known individuals for chemical analyses and behavioral experiments. To test whether wild dogs were territorial, I used VHF and GPS telemetry and direct observations. Wild dogs in northern Botswana exhibited territorial behavior where many territories overlapped with neighbors, however packs avoided being in overlap areas simultaneously. Wild dogs avoid conspecific contact, as these encounters can be dangerous and sometimes resulted in mortalities. Wild dogs scent marked, but did not patrol, their boundaries as might be expected of animals using an impermeable ‘scent fence’. Instead, wild dogs scent marked throughout their territories so intruders encounter increasing number of scent marks as they penetrate resident territories. Through chemical analysis, significant differences were found between the chemical composition of scent marks of male and female wild dogs. Analyses were confounded by the fact that males tend to scent mark at boundaries and females in the interior. To better understand how wild dogs reacted to conspecific scent marks, I moved groups of fecal scent marks from neighboring and non-neighboring packs to measure behaviors of a recipient pack. Recipient dogs consistently investigated scent marks with greatest intensity when those scent marks were from a dominant dog, overmarked by its mate. This is the first study to explore movement patterns and scent marking behavior and chemistry in wild dogs, providing evidence that wild dogs communicate with conspecifics through chemical signals, and likely rely upon scent marks as their primary mode of intraspecific communication. These data offer a platform for further exploration into how managers may manipulate behaviors to reduce conflicts and help conserve wild dogs.
