▼ A large suite of species, across numerous taxa, are expanding their geographic ranges, with potential impacts on species, communities and ecosystems. This has increased interest in understanding the mechanisms driving range change and anticipating future changes in species’ distributions. White-tailed deer have expanded their range into the boreal forest in North America. For northern ungulates, energy expenditure for thermoregulation and movement in winter can exceed energy gain from limited resources, leading to mortality. Substantial changes in climate and land use over the last half of the 20th century may have decreased winter energy loss or increased resource abundance, facilitating range expansion. The objective for this dissertation was to determine the relative importance of climate change and land use as drivers of white-tailed deer range expansion in northern Alberta and to predict how the range may change during the first half of the 21st century. I developed a method to calculate a winter severity index for white-tailed deer using widely available data, and used this mechanistically relevant metric of winter climate in a species distribution model analysis. White-tailed deer presence in the 2000s was explained by a positive relationship with land use footprint, deciduous forest, and growing season length and a negative relationship with winter severity and wetland. The only important land use footprints were agriculture, forestry, and well pads. Model predictions for the northern Alberta boreal region had relatively good accuracy, according to assessments with independent data from the 1970s, 1980s, 1990s, and 2000s decades. Climate was found to be the most important factor driving range expansion in this region. If the shifts toward less severe winters and longer growing seasons continue at the rate observed, white-tailed deer will be able to occupy the majority of the northern Alberta boreal by the 2050s. This increases concern for northern caribou populations and suggests wildlife managers in Alberta face big challenges now and into the future.

▼ Geographical limits of a species’ range are determined in part by the environmental tolerances of that species, and also by its past and current ability to colonize new areas. Range shifts are a common occurrence in the evolutionary history of almost all taxa; however, anthropogenically-mediated activities have facilitated rapid changes in the distribution of many species directly (via introduction) or indirectly (via alteration in habitat or environment). Identification of the pathways underlying range expansion is critical if we are to understand the ecological and evolutionary potential of a species facing changing abiotic and biotic factors. The northern crayfish, Orconectes virilis (Hagen), has rapidly expanded its western range edge along several rivers in the prairies of North America. Although the spatial extent and timing of spread appear to indicate that the species has responded to a large-scale change in environmental conditions, several lines of evidence suggested that human-mediated introduction may also have played a role in range expansion of the species. The species is currently contiguously distributed along rivers across the Interior Plains, but is also found in several lakes and waterways disjunct from the core range. In this thesis I use phylogeographic analysis to identify two genetically distinct O. virilis haplogroups in the region. One haplogroup is spatially and genetically consistent with patterns expected from gradual post-glacial expansion; however, the second is suggestive of frequent and widespread introduction. I developed microsatellite markers that allowed me to assess fine-scale intra-river genetic patterns associated with spread of O. virilis. I found that genetic patterns were not consistent across rivers, and that recent range expansion has resulted from a combination of natural spread and human-mediated introduction. Two groups of crayfish-associated symbionts were found on O. virilis in the Interior Plains, branchiobdellidan worms and entocytherid ostracods. The distributions of these organisms suggest that factors affecting range limits differ among host and symbionts. Little is known of the ecology and evolution of these symbionts, not only in the Prairies, but also across their global distribution. My examination of phylogenetic patterns of North American branchiobdellidans provides the best supported evolutionary hypothesis of the order to date.

▼ The mountain pine beetle (Dendroctonus ponderosae Hopkins) is the most aggressive bark beetle (Coleoptera: Curculionidae) in western North America. This insect is currently expanding its range eastward through the Canadian boreal forest. Continued range expansion, or introduction via infested material from western North America, could lead to novel associations between the mountain pine beetle and eastern pines. This research seeks to determine the susceptibility and suitability of pine species common to northeastern North America for mountain pine beetle. Studies were conducted in a common garden environment on logs of four common eastern pines, red (Pinus resinosa), jack (P. banksiana), eastern white (P. strobus) and Scots (P. sylvestris) pine, and two historic hosts, lodgepole (P. contorta) and ponderosa (P. ponderosa) pine. Constitutive defenses pose no significant barrier to colonization of eastern pines by mountain pine beetle. The proportion of female beetles that established fertile egg galleries differed among eastern pines, but were similar to historic hosts. Foraging beetles were generally no more attracted to logs of eastern pines containing boring beetles than to a control. Chemical analysis of the phloem suggests that host kairomones critical for secondary attraction were minimal among novel pines and likely resulting in less attraction than to historic hosts. Overwintering capacity of developing brood was affected by eastern pines. Rapid development in novel pines resulted in greater proportions of brood entering winter in less cold tolerant life stages than historic hosts. The strategy and degree of cold tolerance of fourth instars were affected by natal pine host. Field validation of logistic regression models demonstrated that models based on the insect freezing temperature underestimate cold mortality, while lower lethal temperature curves more accurately project mortality due to cold. Finally, we found that constitutive defenses pose no barrier to reproduction among novel pines. Indeed, novel pines can have up to twice the reproductive potential, and demonstrate greater brood fitness than historic hosts. However, variable rates of development among novel hosts could result in desynchronized or extended emergence periods in mixed stands. Matches between species specific development rates and climate will be crucial for outbreaks to occur in eastern forests.

▼ Range expansion of an invasive species can be influenced by intrinsic mechanisms such as behaviours described as being highly flexible and/or of specific behavioural types that are associated with dispersal ability. In addition, related gene transcription can also be influential in invasion success, promoting acclimation to novel environments. My study species, the round goby (Neogobius melanostomus), is an invasive fish continuously expanding its range in the Laurentian Great Lakes and its tributaries. This thesis aims to examine: 1) the behavioural repertoire of the round goby 2) differential gene transcription for gobies “natural” and environmental captive “treatment” using brain candidate genes associated with behavioural traits specific to aggression, boldness, stress response, learning, and activity; and 3) how behaviour and gene transcription vary between residents and dispersers and detection time since North American invasion. I found that round goby possess an “invasion behavioural phenotype” consisting of boldness, exploration, sociality and predator habituation. In addition, I found juveniles were bolder, explored more, were social and habituated to predation more compared to adults, but more so at established sites than recently invaded ones, contrary to predictions. Adults did not show any overall invasion stage differences, possibly due to conspecific densities, habitat-feature differences, and/or time-since-first detection. I showed evidence that there could be a genetic mechanism driving these behaviours, genes expressed for the “natural” group (aggression, stress-response, learning). My natural gene transcription results support that detection time can result in differences most likely driven by density, but round gobies are most likely able to produce “alternative ontogenies” due to plasticity, where individuals acclimatize to novel stressors over time, resulting in shifts in phenotypes. By examining all the facets that could drive range expansion one can gain a deeper insight underlying “invasiveness”. Advisors/Committee Members: Semeniuk, Christina, Heath, Daniel.

▼ Phenotypic plasticity and genetic diversity are theorized to contribute to species’ successful colonization and range expansion; however, there is a lack of consensus in the invasion biology literature about their role in predicting invasion success. Much of the existing empirical research suffers from a lack of knowledge regarding failed or unsuccessful invasions. This reflects the scientific community’s priority for understanding the worst invaders. To address these gaps in knowledge, I used a novel comparative approach of taxonomically and geographically paired invasive species, representing successful and less-successful invaders, to investigate the potential of phenotypic plasticity for gene transcription and genetic diversity at both neutral and functional genetic markers to predict invasion success (Chapters 2, 4 and 5). I also addressed genetic and environmental underpinnings of phenotypic plasticity for gene transcription (Chapter 3) to improve the use of transcriptional variation to predict invasion success and range expansion. A highly successful biological invader was more transcriptionally plastic to temperature change, with a stronger transcriptional response and wider range of biological functions, than a comparatively less successful invader (Chapter 2). Transcriptional variation for core metabolic and stress response genes is primarily driven by the environment (Chapter 3) suggesting that, while transcription for potential invaders must be assayed under a range of conditions, knowledge of these responses will allow prediction of transcriptional profiles and thus an organism’s potential performance in, as yet, un-invaded areas. Low relative invasion success was associated with decreased levels of within- but elevated levels of among-population genetic diversity for two of four species pairs (Chapter 4). These results imply that genetic diversity is limiting for some invasive species’ range expansions and highlight the role that intraspecific hybridization may play in promoting invasion success. Compared to native range populations, tubenose goby have experienced a loss of genetic diversity while round goby have not. Round goby exhibit more adaptive divergence within the invaded range indicating that tubenose goby range expansion may be limited by its inability to evolve to facilitate range expansion (Chapter 5). Thus, both phenotypic plasticity and genetic diversity are important for successful range expansion and predicting colonization potential. Advisors/Committee Members: Heath, Daniel.

▼ Introduced species cause both considerable ecological and economic damage every year. However, not much is known about how certain species are able to establish and spread beyond the site of initial introduction, whereas others do not. Species undergoing range expansion following an introduction may prove to be a valuable resource to invasion biology, but may also be informative in light of species' responses to changing environments (i.e. global climate change). Here, I took advantage of an ongoing range expansion of an introduced vertebrate species. House sparrows (Passer domesticus) were introduced to Mombasa, Kenya in the 1950s and have subsequently expanded their range northwest-ward and now occupy most major cities in Kenya. By comparing older, established populations (i.e. those in Mombasa) with more recently colonized populations at the range edge, it might be possible to determine some of the mechanisms that underlie range expansion in some species and/or populations. In Chapter 1, the background and ideas that motivated the rest of the dissertation is summarized. In Chapter 2, I studied how exploration and glucocorticoids (a hormone released in response to stressors) changed throughout the range expansion. Exploration was greater at the range edge, which is likely to ensure greater discovery of novel resources. Glucocorticoids released in response to restraint were also highest at the range edge, which might facilitate resolution of stressors in unpredictable environments. However, chronically elevated levels of glucocorticoids are often considered maladaptive, unless an individual can appropriately cope with them. Therefore, in Chapter 3, I characterized glucocorticoid receptors (i.e. mineralocorticoid receptor (MR) and glucocorticoid receptor (GR)) in the hippocampus, an area responsible for negative feedback of glucocorticoids as well as induction of behavioral and physiological response to stressors. I found that MR density was lower relative to GR density at the range edge compared to the site of introduction (Mombasa). I speculate this pattern is a mechanism to resolve the elevated levels of glucocorticoids at the range edge. Taken together, these results indicate that individuals at the range edge have a strong glucocorticoid response to stressors to induce a rapid, strong response to resolve stressors. Subsequently, in Chapter 4, I examined the potential mechanisms of phenotypic change among Kenyan house sparrows. Typically, following an introduction event, genetic diversity undergoes a bottleneck and is greatly reduced compared to the source population; as such, genetic evolution as the main driver of changing phenotypes throughout the range expansion is unlikely. We therefore hypothesized that epigenetic mechanisms (e.g. DNA methylation) may compensate for the expected reduced genetic diversity following an introduction. Although there was no pattern of epigenetic variation among cities (i.e. variation did not increase nor decrease further from the site of introduction),…

A cause de l’actuel déclin mondial de la biodiversité, la compréhension des conséquences de chaque menace sur la biodiversité est un élément crucial en biologie de la conservation. Les espèces exotiques envahissantes représentent une de ces menaces à l’échelle mondiale, et peuvent induire localement des dommages au sein des écosystèmes. Etudier les phénomènes régissant les effets négatifs de ces espèces, et leurs potentiels d’expansion apparaît actuellement comme un élément crucial pour déterminer leurs effets sur le long terme. Dans cette étude, nous focalisons nos efforts sur une population exotique envahissante du Xénope lisse, Xenopus laevis, en France, pour apporter de nouvelles connaissances sur les interactions de cette population avec son environnement et pour étudier les changement dans l’allocation des ressources aux traits d’histoire de vie liés à la reproduction la survie et la dispersion durant l’expansion de l’aire de répartition. Nous étudions le régime alimentaire de l’espèce en France et dans d’autres populations introduites et autochtones et concluons que cette espèce peut étendre sa répartition en consommer une faible, comme une importante diversité de proies. Nous détectons également un potentiel impact de l’espèce sur les amphibiens autochtones de France. Dans la seconde section de la thèse, nous rapportons une réduction de l’allocation des ressources à la reproduction et une augmentation de la dispersion, sur le front de colonisation. Enfin, nous étudions la dynamique des populations et détectons une faible probabilité de survie, et une faible densité en individus dans le centre de l’aire de répartition. La combinaison de ces résultats suggère que les potentiels effets négatifs sur le long terme sont importants pour cette espèce, en France, tout comme dans d’autres zones où l’espèce a été, ou sera, introduite.

Because of the current global biodiversity decline, understanding the consequences of each threat on biodiversity is crucial for conservation biology. Invasive species are among the main threats at the global scale, and can locally imply harmful damages on ecosystems. Studying the phenomena driving the effects and potential for expansion of these species appears as a crucial element to assess their long terms impacts. In this study, we focused our efforts on an invasive population of the African clawed frog, Xenopus laevis, in France, to bring insight about the interactions of this population with its environment and to study the changes in resource allocation to the life history traits, related to reproduction, survival and dispersal probabilities, during the range expansion of the population. We studied the diet in the French invasive population and in other invasive and native populations, and found that this species can expand by predating a narrow, as well as a broad, range of prey categories. We also detected an impact of X. laevis on the native amphibian community in France. In the second section of the thesis, we reported a decrease in reproductive investment, and an increased…

▼ In Pennsylvania, the black bear (Ursus americanus) population has expanded its range since the early 1980s. I investigated if dispersal timing, distance, and rates changed compared to previous research, and if those changes corresponded with range expansion and increasing population density. I used records of bears captured and ear-tagged <16 months of age with specific locations of tagging and recapture or dead recovery encounters (n = 466). I classified bears as dispersed if the measured distance between initial capture and final recovery was ≥13 km, which was the greatest linear distance across the average female bear home range in Pennsylvania. Based on this criterion, I classified <5% of bears as dispersing <16 months of age and dispersal occurred at 16–19 months of age. I estimated dispersal rates using logistic regression models, to investigate if dispersal differed by region or decade for males and females. Median distance dispersed was greater for males (47.03 km, n = 98) than females (25.84 km, n = 70). Region of Pennsylvania and decade were not related to the distance bears dispersed. Overall, male dispersal rate was 0.67 (SE = 0.06) and female dispersal rate was 0.28 (SE = 0.06). For males, I found that dispersal rates were 0.48 in the 1980s and increased to >0.75 in the 1990s and 2000s but did not vary by region of Pennsylvania. No single logistic regression model best explained female dispersal so I used model averaging to estimate dispersal rates by decade and region. The greatest increase in female dispersal rates occurred between the 1990s and 2000s in all regions. My results indicated a greater dispersal rate, at greater distances, for female bears than previous research in Pennsylvania but dispersal characteristics of males were similar to previous research. My results indicated that dispersal by females, especially at the edge of the species range in Pennsylvania, was likely important to the rate of range expansion of bears in Pennsylvania.

▼ The performer's conceptualisation and perception of herself is projected through the acoustic voice and impacts upon vocal delivery in rehearsal and performance. However, in the context of performer voice training in Western theatre practice the performer's sense of self, or identity, is seldom the focus of development. Vocal development is inherently a transformational process that requires the performer to expand beyond what has become habitual selfexpression. Since vocal expression is embedded in identity, an attempt to change the voice necessitates a deeper understanding, questioning, and challenging of the performer's established sense of self. In this dissertation I posit that acoustic vocal development can be successfully achieved through an embodied and imaginative approach that investigates the performer's metaphorical voice through learning opportunities provided by a process that integrates the practices of Voice Movement Therapy (VMT) and maskwork. This dissertation presents art-based autoethnographic research into the potential value of such an integrated approach to performer vocal development. The VMT maskwork approach is fundamentally an embodied and envoiced process that provides a vastly different and heightened experience of the bodymind and invites the performer to play in the liminal realm of active imagination, which is triggered by the mask-image. The dissertation investigates the vocal development benefits of using self-made masks as a psychophysical training tool to expand the performer's understanding and experience of the bodymind. The area of archetypes and subpersonalities has been identified as a primary intersection between the two modalities and three ways of working are proposed, either taking impulses from the image (mask-image and/or imagination), the body and its movement, or the voice. These three ways of working trigger the bodymind into a process of active imagination that evokes a creative and integrated mask-voice-body exploration of archetypes and/or subpersonalities. The process gives permission to, and provides a safe container for, the amplified expression of the extremes of self and voice. This dissertation offers a tri-phase VMT maskwork process structure, and highlights key steps for the VMT practitioner-led facilitation of such a process. It positions the mask as a useful transitional object which encourages reengagement with imagination, body, voice and emotion, and thus encourages an on-going and multi-layered reflection and investigation of self and voice is possible. The research showed that the integrated approach of VMT maskwork resulted in vocal expansion in all 10 of the VMT 10 vocal components; pitch, pitch fluctuation, loudness, glottal engagement, free air, disruption, violin, register, timbre and articulation. Apart from acoustic vocal expansion, the approach fostered expansion in the performer's metaphorical voice and resulted in improved grounding and confidence in performance. These conclusions support the research… Advisors/Committee Members: Munro, Marth (advisor).

Biotehničke nauke - Pejzažna arhitektura i hortikultura / Biotechnological sciences - Landscape architecture and horticulture

Predmet istraživanja doktorske disertacije je ekologija i biologija invazivne vrste Aster lanceolatus Willd. complex (fam. Compositae). U okviru ovog predmeta, definisani su ciljevi planiranih istraživanja: da se utvrde kvantitativni odnosi vrste A. lanceolatus i drugih cenobionata na staništima koja su zahvaćena invazijom ove vrste; da se utvrde i objasne mehanizmi kojima vrsta utiče na procese u istraživanim ekosistemima; da se utvrdi uloga generativnog i vegetativnog razmnožavanja u procesu širenja vrste A. lanceolatus; da se utvrde kauzalni odnosi između regionalnog klimatskog modela i predikcije rasprostranjenja vrste i da se izvrši analiza rizika od vrste A. lanceolatus. Istraživanja su sprovedena na terenu i laboratoriji po utvrđenoj metodologiji. Rezultati istraživanja su pokazala da vrsta A. lanceolatus naseljava staništa na kojima su izražene različite vrste poremećaja, da je dominantna na većini istraživanih lokaliteta i da potiskuje druge vrste u zajednicama i staništima na kojima se nalazi, čime je i potvrđena prva postavljena hipoteza. Postavljena hipoteza da vrsta A. lanceolatus utiče na osobine zemljišta i tako doprinosi svojoj kompetitivnosti nije u potpunosti potvrđena. Sa druge strane, hipoteza ne može da bude ni odbačena, jer su određene promene u zemljištu konstatovane. Gajenjem biljaka u hidrokulturi je utvrđeno da vrsta A. lanceolatus ima snažan vegetativan rast, da u početnoj fazi rasta alocira resurse u podzemni deo, da pri interspecijskoj kompeticiji često nadjačava vrstu Achillea millefolium L., kao i da ima veliki potencijal za vegetativno razmnožavanje. Rezultati dobijeni gajenjem biljaka u hidrokulturi i ispitivanjem klijavosti semena potvrđuju hipotezu da je i vegetativno i generativno razmnožavanje značajno za proces širenje vrste A. lanceolatus. Uz rezultate sprovedenih bioloških testova, identifikacija i kvantifikacija 14 fenolnih jedinjena u biljnim organima vrste A. lanceolatus predstavljaju potvrdu alelopatskog dejstva ove vrste, čime je i potvrđena postavljena hipoteza. Hipoteza da klimatske karakteristike utiču na širenje invazivne vrste A. lanceolatus je potvrđena, jer su rezultati primenjenog modela pokazali, da će sa povećanjem temperature rasti i potencijal širenja ove vrste.

▼ Range expansion is a fundamental population-level process that plays an essential role in establishing past, present, and future species distributions. Understanding the dynamics of range expansion is increasingly important in the current era of anthropogenic change, where species distributions are being modified due to climate change, land-use change, conservation efforts, and invasions by noxious pests. However, range expansion dynamics are difficult to predict; expansions are complex and highly variable processes shaped by ecological and evolutionary forces. Understanding how these forces interact to drive range expansion dynamics has only recently begun to be investigated. Longstanding theory indicates that the speed of range expansion is determined by the ecological processes of dispersal (the rate at which individuals move from one spatial location to another) and the low-density reproductive rate (the rate at which individuals produce offspring in environments where conspecific densities are low). Recent theory has suggested that populations at the leading-edge of expanding ranges are subject to evolutionary forces that can rapidly modify their dispersal and reproductive rates in ways that make range expansions faster and more variable. Dispersal provides a means for individuals in an expanding population to become spatially sorted by dispersal ability. This ‘spatial sorting’ is expected to cause the over-representation of highly dispersive individuals at the leading edge of an expansion, increasing the probability of non-random mating structured by dispersal ability. If dispersal is heritable, highly dispersive individuals at the leading edge are expected to pass dispersal-related traits to their offspring, an effect which increases the speed of range expansion over multiple generations. Furthermore, relative fitness advantages caused by reduced conspecific competition at the low-density range edge may result in two additional selective mechanisms: selection for increased reproductive rates (natural selection) and selection for increased dispersal ability (‘spatial selection’). Developing useful expectations for the dynamics of range expansion thus requires detailed investigations into how these phenomena interact, and how they may be modified by additional population-level processes common to biological systems. Chapter One of this thesis provides one of the first experimental tests of spatial sorting, using laboratory populations of the bean beetle Callosobruchus maculatus. It finds clear evidence that spatial sorting increases the speed and variability of range expansions. It identifies the rapid evolution of dispersal ability as having caused the increase in speed, and suggests that the random accumulation of genotypes at the leading edge (i.e., ‘gene surfing’) is responsible for the increase in variability. Chapter Two measures the heritability of dispersal and low-density per-capita reproductive rate in C. maculatus, as well as the genetic and environmental correlations between these traits, and builds… Advisors/Committee Members: Miller, Tom EX (advisor).

▼ The walnut twig beetle (Pityophthorus juglandis Blackman) is a domestic alien invasive bark beetle in the United States of America (USA) that vectors a phytopathogenic fungus. Together, the beetle and fungus cause thousand cankers disease in species of Juglans and Pterocarya. Geographic range expansion by P. juglandis from its native range in the southwestern USA throughout the western United States and isolated areas of the eastern United States provides evidence for human-mediated movement. The disease is now present in more than 120 counties on naïve native and cultivated hosts in the eastern and western USA and in northern Italy. This research describes the cold mortality and host suitability of P. juglandis. I measured the cold tolerance of P. juglandis adults and larvae from a northern California population monthly from January 2013 to May 2014. I found significant seasonal changes in adult supercooling points in fall, winter, and spring. I observed a shift in cold-tolerance strategy in P. juglandis adults from freeze-intolerance (December 2013 and January 2014) to partial freeze-tolerance (February 2014). Adults appear to be more cold-hardy than larvae. Predicted winter survivorship in the southeastern USA is higher than in the northeastern USA. I conducted field and laboratory trials to determine if reproduction by P. juglandis varies between two black walnut (Juglans nigra L.) parent trees and black walnut and butternut (Juglans cinerea L.). Fewer adult offspring developed in branch sections of the black walnut maternal ‘Sparrow’ parent than the paternal ‘Schessler’ parent over three summer months and one winter month in the lab. In the field, P. juglandis reproduction in black walnut and butternut did not differ. In an expanded laboratory study of host suitability, I screened 11 Juglans spp., one Pterocarya sp., and two Carya spp. over two years. Eleven Juglans and one Pterocarya species supported complete brood development. Julgans nigra, J. californica, and J. hindsii had the greatest levels of reproduction. Less suitable hosts include native southwestern United States hosts (J. major and J. microcarpa), Eurasian species (J. regia), Asian butternuts (J. ailantifolia, J. mandshurica, and J. cathayensis), and native eastern United States butternut (J. cinerea) and Japanese walnut-butternut hybrid (J. ailantifolia × cinerea). The two Carya species were not hosts. Finally, I present a framework that provides strategies for accessing stakeholder knowledge of unspecified pathways that may move forest insect pests. Using social science, stakeholder analysis, and design principles, the framework provides risk managers a tool to consult stakeholders for pathway information. The result is a list of pathways that can be validated independently. My research provides biological information of the potentially limiting factors of the spread and establishment of P. juglandis. Although the impacts of thousand cankers disease appear variable, the probability of exposure of walnut to P. juglandis…

▼ The goal of this dissertation is to further our understanding of how spatially heterogeneous landscapes may impact the formation of range boundaries that then aggregate to form large-scale biodiversity patterns. These patterns have been analyzed from many different perspectives by ecologists, evolutionary biologist, and physiologists using a variety of different theoretical, statistical, and mechanistic models. For some species, there is an obvious abrupt change in the environment causing a range boundary. Other environments change gradually, and it is unclear why species fail to adapt and expand their range. The first chapter develops a novel theoretical model of how the establishment of new mutations allows for adaptation to an environmental gradient, when there is no genetic variation for the trait that limits the range. Shallow environmental gradients favor mutations that arise nearer to the range margin, have smaller phenotypic effects, and allow for proportionately larger expansions than steep gradients. Mutations that allow for range expansion tend to have large phenotypic effects causing substantial range expansions. Spatial and temporal variation in climatic and environmental variables is important for understanding species response to climate change. The second chapter uses a mechanistic model to simulate switchgrass (Panicum virgatum L.) productivity across the central and eastern U.S. for current and future climate conditions. Florida and the Gulf Coast of Texas and Louisiana have the highest predicted current and future yields. Regions where future temperature and precipitation are anticipated to increase, larger future yields are expected. Large-scale geographic patterns of biodiversity are documented for many taxa. The mechanisms allowing for the coexistence of more of species in certain regions are poorly understood. The third chapter employs a newly developed wavelet lifting technique to extract scale-dependent patterns from irregularly spaced two-dimensional ecological data and analyzes the relationship between breeding avian richness and four energy variables. Evapotranspiration, temperature, and precipitation are significant predictors of richness at intermediate-to-large scales. Net primary production is the only significant predictor across small-to-large scales, and explains the most variation in richness (~40%) at an intermediate scale. Changes in the species-energy relationship with scale, may indicate a shift in the mechanism governing species richness. Advisors/Committee Members: Keitt, Timothy H.

▼ As climate change and anthropogenic disturbances threaten an array of communities, identifying factors that shape species’ distributions is critical. Examining a species undergoing range expansion can reveal factors driving its distributional change. Determining traits that make a species resilient to ongoing changes will improve our ability to predict responses to fluctuating environmental pressures. With ancestors that evolved in the Neotropics, the Virginia opossum, Didelphis virginiana, baffled zoologists by its expansion into areas with harsh winters. In my dissertation, I evaluated morphological, ecological, and genetic factors that may explain how the opossum expanded beyond its hypothesized climate niche. For my first three chapters, I analyzed stable isotopes of carbon (δ13C) and nitrogen (δ15N) from guard hairs from opossums in a wildlife center and from museum institutions. In my first chapter, I evaluated isotope values of captive and wild opossums for evidence of biannual or incomplete biannual molting, a mammalian adaptation to harsh winters. My results suggest opossums do not exhibit either winter molting strategy, and that guard hairs capture the opossum’s lifetime diet. In my second chapter, I used isotope values to test the hypothesis that a Type A generalist’s niche is positively correlated with habitat heterogeneity and to evaluate which climate variables best explained isotope values. I found a positive correlation between isotopic niche size and habitat-diversity indexes. Climate variables that represent aridity and C4 plant abundance were positively associated with δ15N and δ13C values, respectively. The results reveal that opossums’ isotopic compositions are shaped by the habitat in which they are found, as would be expected in a generalist species. In my third chapter, I used δ13C values from opossums in the Midwest and Northeast to test whether opossums rely on anthropogenic trash to survive extreme winters. There was no significant relationship between δ13C and winter variables, but there was a significant increase in variance of Midwest opossums’ δ13C after the 1970 corn agricultural boom. The patterns observed for northern opossums suggest their foraging is influenced by agricultural land but not urban trash. In my final chapter, I used reduced-representation genome sequencing to evaluate how opossums spread into temperate North America. Bayesian clustering analysis identified four genetic clusters, with one cluster limited to the Yucatan Peninsula, one cluster found across Mesoamerica, and two clusters that largely co-occurred in temperate North America. I used approximate Bayesian computation to evaluate 19 phylogeographic scenarios. The best-performing scenario posited a single expansion into temperate North America, followed by divergence. Alternatively, the two temperate clusters may be a result of incomplete lineage sorting. Because opossums do not exhibit classic mammalian adaptations to winter, their expansion into areas considered to be too harsh for them has previously been… Advisors/Committee Members: Tucker, Priscilla K (committee member), Dantzer, Ben (committee member), Badgley, Catherine E (committee member), Davis Rabosky, Alison R (committee member).

▼ La daurade royale (Sparus aurata) est une espèce de sparidé dont l’aire de répartition s’étend des côtes du Sénégal à l’Irlande, et est commune en mer Méditerranée. Elle est considérée comme rare en limite nord de répartition (Manche, mer d’Irlande et mer du Nord). Depuis une dizaine d’années, l’abondance d’individus pêchés en limite nord ne cesse d’augmenter. Ce phénomène peut être expliqué par l’évolution septentrionale de son aire de répartition, en lien avec le réchauffement climatique. Aucune donnée écologique sur les populations de cette espèce en limite nord de répartition, devenues une ressource de pêche en Manche, n’est actuellement publiée dans la littérature. Les traits de vie de S. aurata ont été étudiés face à la modification spatio-temporelle de son aire de répartition, via l’analyse du régime alimentaire, de la croissance et des déplacements côtiers. D’autre part, l’étude a conduit à l’analyse de la structure de ces populations septentrionales par une approche multi-marqueur couplant la génétique et la microchimie des otolithes.L’analyse des contenus stomacaux des populations de S. aurata en limite nord de répartition confirme un régime opportuniste, avec une forte proportion d’espèces-proies du genre Mytilus. Malgré un régime alimentaire similaire, la croissance des individus est, quant à elle, plus faible que celle observée sur des individus de mer Méditerranée, ce phénomène étant conditionné par les paramètres du milieu (température, salinité). Les variations élémentaires des otolithes ont permis de caractériser les migrations côtières lors des premières années de vie des poissons avec un passage en mer en hiver et la fréquentation de zones côtières. Cela suggère la présence de zones de nourricerie le long du pourtour atlantique et de la Manche. Une variabilité inter-individuelle a été mise en évidence suggérant une plasticité comportementale des individus. Les approches de génétique, combinant l’emploi de marqueurs mitochondriaux et des microsatellites, et de microchimie des otolithes ont mis en évidence l’absence de structure au sein des populations en limite nord de répartition. Ce phénomène concorde avec la colonisation récente des populations. Cependant, une différenciation entre les individus échantillonnés le plus au sud et ceux en limite nord d’échantillonnage a été mise en évidence, suggérant peu de mélange génétique. Les allèles communs entre les individus échantillonnés évoquent une colonisation des individus de proche en proche depuis la mer Méditerranée. Des différences génétiques et de traits de vie ont été observées entre les individus échantillonnés en Manche, suggérant l’existence d’une barrière biogéographique au sein de cet environnement. La présence de conditions environnementales favorables constitue un atout majeur pour cette espèce prédatrice qui semble présenter une capacité d’acclimatation importante. L’ensemble des approches abordées dans le cadre de ces travaux ont permis d’apporter les premières données sur les traits de vie et la structure des populations d’une espèce à… Advisors/Committee Members: Duhamel, Guy (thesis director), Denis, Françoise (thesis director).

▼ The pine marten (Martes martes) has been long considered a prototypical forest-specialist, but recent studies carried out in western Europe have pointed out that the species is more generalist in terms of habitat preferences than previously reported. In the western plain of the River Po residual woods mainly consist of small patches or riparian woods merged in intensively cultivated areas; nonetheless in this apparently unsuitable area the number of roadkill pine martens has increased exponentially since the beginning of the century. The expansion of the pine marten in agricultural lowlands provided an invaluable opportunity for investigating its ecological requirements and the environmental factors that shape this species’ range. To assess the actual level of pine marten penetration in lowland areas of north-western Italy, a non-invasive, faecal mDNA-based genetic method was applied at landscape scale, demonstrating that the pine marten has colonised the overall study area north of the River Po, which probably is acting as a barrier. Pine marten distribution suggests that expansion has mainly followed a north-to-south direction, following the course of major rivers as natural corridors of expansion. The unexpected high frequency of haplotypes of the central-northern European phylogroup supported the hypothesis of Alpine or trans-Alpine populations as sources of pine marten expansion. Based on presence-absence data, Species Distribution Models were applied to identify the main factors driving the colonisation by the pine marten of the western River Po plain and predict its potential south- and eastwards expansion. The distribution of residual wood patches and availability of suitable riparian corridors played a major role in shaping the potential expansion area of the pine marten in agricultural lowlands. This was high only for the western part of the River Po plain and, secondarily, for the pine wood patches bordering the Adriatic coast. The hypothesis that lowland woods may represent marginal habitats for the pine marten was not supported by the data collected about both its density and macronutrient balance. In the valley of the River Ticino, microsatellite analysis of faecal DNA allowed to point out one of the highest densities ever recorded in continental Europe. The high genetic relatedness of identified individuals suggested that the agricultural matrix may act as a barrier to the dispersal of juveniles. Genotyping allowed also to test for the effectiveness of a camera-trapping-based method (Random Encounter Model) for assessing pine marten density. The REM underestimated population size by ca. 40%. Dietary macronutrient ratios of pine marten differed from the target, as assessed by the meta-analysis of available diet data for Europe, to an almost negligible extent, confirming that plasticity in feeding behaviour plays a major role in pine marten expansion in agricultural areas. Genetic surveys confirmed that pine marten expansion is coinciding with a reduction in stone marten range or abundance. When… Advisors/Committee Members: tutor: N. Siano, coordinatore: N.

▼ The resurgence of West Nile virus (WNV; Family Flaviviridae, genus Flavivirus) in Ontario, Canada in 2012 demonstrated that there is a great need for a reassessment of the local mosquito fauna, estimation of risk of WNV transmission, and the creation of effective arboviral awareness campaigns. A review of the current literature and collection databases revealed that there are 68 mosquito species known from Ontario (Chapter 2). Ten species were added to the list of species including Culex erraticus (Chapter 3) and Aedes albopictus (Chapter 4), both of which are capable of transmitting West Nile virus. Ae. albopictus was repeatedly collected from Windsor, Ontario in 2016 (Chapter 4). Immatures (n=78) were collected from tires, StyrofoamTM containers, and discarded garbage. Adult female (n=17) and male (n=2) specimens were collected from light traps (n=7) and Biogents-Sentinel traps (n=10). Additional specimens were obtained from Franklin County, Ohio. The generated gene tree and Bayesian cluster analysis grouped sequences described from Ohio and Windsor together on the same branches. Together these data suggest that the population in Windsor originated as a founder population of North American origin by means of human-aided dispersal. Mosquito abundance predication surfaces and seasonal distributions were attempted for each vector species to identify where and when vector species are most abundant in southern Ontario (Chapter 5). Spatial prediction surfaces using kriging were created for Aedes vexans, Aedes japonicus, Culex pipiens, Culex restuans, and Ochlerotatus trivittatus. Proximity to landscape variables was observed to improve model prediction. An epidemiological analysis of WNV human case prevalence and mosquito infection was conducted (Chapter 6). A strong quadratic relationship between the number of human cases and positive mosquito pools at the end of each year was observed (R2=0.9783, p < 0.001). Spearman rank correlation tests identified mosquito infection rates as the strongest predictors of human case prevalence at a one-week lag period. Average temperature was a strong predictor of mosquito infection rates. Cumulative positive Culex pools recorded by epidemiological week 34 is a sufficient action threshold for West Nile virus epidemics. These data have the potential to contribute to a more efficient West Nile virus awareness campaign.

▼ Invasive species are problematic but their control can be difficult. When the history and dynamics of invasive populations are unknown, analytical techniques utilising genetic data can provide information to management. The application of these techniques has typically been limited to species with restricted dispersal or to localised geographic scales. Here these techniques are used in conjunction with traditional approaches to study the invasion of a highly vagile species over a continental scale. Originally introduced to eastern Australia, the common starling (Sturnus vulgaris) is expanding westward and has reached the southeast agricultural region of Western Australia (WA). Spatial, temporal and museum samples representing historical incursions into WA were used in genetic analyses to answer questions important to WA management agencies. Where possible, multiple marker classes were used to evaluate their relative ability to address these questions, including microsatellites, mitochondrial DNA (mtDNA), and a nuclear gene. Between two and four genetic groups were identified in Australia, and the localities on the edge of the range expansion (ERE) were consistently genetically differentiated from all others. Levels of genetic exchange between groups appeared to be low, suggesting that localised control may be effective. Analyses of historical samples indicated patterns of genetic exchange are temporally stable. This suggests that starlings will continue to arrive from the east, requiring vigilance from management. Consistently, a negative relationship was found between genetic diversity and date of first record, which may help in the future to distinguish ineffective surveillance from recent colonisations. Genetic evidence of female-biased dispersal indicated that control strategies preferentially targeting females may more efficiently limit dispersal than those targeting both sexes equally. Variants private to particular genetic groups were identified; tracking the spread of these variants may assist future monitoring programs in understanding ongoing exchange between groups. One mtDNA variant private to ERE localities showed dramatic temporal change, which could not be adequately explained by genetic drift or admixture, but may be explained by selection. Microsatellites were most useful in determining origins and identifying dispersers, mtDNA sequences provided a unique tool for ongoing monitoring of dispersal, and nuclear sequences had high levels of gene diversity and resolution of population structure.

▼ Biological invasions have received considerable attention because of the increasing frequency with which they occur and the damage they can inflict on ecosystems. However, invasions are ideal study systems not only because of the insight they provide about management and preservation of biodiversity, but also because they can be used to answer a variety of ecological and evolutionary questions. In this series of studies I used the invasions of tropical geckos in urban habitats to address questions about range expansion and species replacement during invasion of an occupied niche. I used both the invasion of A-clones and replacement of B-clones of Lepidodactylus lugubris in Hawaii and the invasion of Hemidactylus mabouia and replacement of H. garnotii in Florida as models to test hypotheses about the process of range expansion and species replacement. To test hypotheses about the mechanisms and consequences of range expansion at multiple spatial scales, I developed 12 novel microsatellite markers in H. mabouia and used them to determine patterns of gene flow at both a very fine scale (tens of meters) and at a very large scale (statewide). To test hypotheses about species replacement, I used both laboratory studies and field studies to document mechanisms and timing of species replacement during invasion. In L. lugubris, I used controlled laboratory experiments to determine the behavioral mechanisms underlying the advantage of A-clones in the human environment. In H. mabouia, I used field census data from many locations in Florida to determine the rate at which H. garnotii was displaced during invasion. I found that dispersal was limited at a very fine spatial scale in H. mabouia, and that population structure arises at the leading edge of range expansion but erodes as the populations approach migration-drift equilibrium. I also demonstrated that human-mediated dispersal at the statewide scale plays a role in the rapid range expansion of H. mabouia. These findings demonstrate the importance of looking for population structure at multiple spatial scales, and also suggest that drift may be an important evolutionary force at small scales, despite higher levels of gene flow at larger scales. My studies of species replacement showed that it can occur very quickly, and that behavioral mechanisms of replacement likely contribute to rapid displacement of resident species during invasion. Together, these findings represent one of very few studies of range expansion and species replacement in terrestrial systems. Advisors/Committee Members: Petren, Kenneth (Committee Chair).

▼ Environmental change and anthropogenic activities influence species distributions. Species introductions have become increasingly common in an era of globalization and increased international trade and travel. The establishment of introduced species outside their native range and subsequent spread are of great conservation concern. Introduced species that become invasive, spread rapidly and reach high abundance, may cause the extinction of native species, disrupt ecosystem functioning and pose a threat to human health and the economy. It is therefore of great interest to understand the processes and mechanisms involved in species range expansion in order to develop effective management strategies. In this thesis I examine the influence of the landscape on species’ distribution and analyse patterns of range expansion of a non-native insect in south-central Sweden. Roesel’s bush-cricket (Metrioptera roeselii) was chosen as a model organism as its biology is well studied and its range expansion has been documented not only in Sweden but also in several other European countries. The aims of this thesis were (I) to identify landscape variables that predict the species distribution, (II) to estimate the rate of range expansion, (III) to identify the source of range expansion in south-central Sweden and to assess the dispersal pattern using population genetic data, and (IV) to analyse the influence of landscape composition and structure on population connectivity. I analysed species distribution, genetic and landscape data using a range of statistical modelling techniques in combination with geographic information systems (GIS). The results showed that the amounts of arable land, pasture and rural settlements as well as linear habitat elements are important predictors of the species’ distribution. During the last three decades, Metrioptera roeselii has expanded its range from the northern shores of the Lake Mälaren at an estimated rate of 0.3 - 3.16 km/year. The genetic diversity across the range was surprisingly high and degree of population differentiation was low to moderate likely due to frequent gene flow between populations in the centre of the species range and decreased gene flow towards the range margin. It appears the species establishes populations through infrequent long-distance and frequent short-distance dispersal (natural, human-mediated).
