▼ This study assesses artificial burrows as a management tool for burrowing owls (Athene cunicularia) at two study sites in northern California. The results of t-tests showed that artificial burrows that received annual surface maintenance (n = 113) at one site were occupied for a significantly (p ≤ 0.003) greater number of years than non-maintained (n = 51) artificial burrows at the other site. Maintained burrows were occupied for a mean of 1.90 years (SD = 2.04), compared to a mean of 0.45 years (SD = 0.97) for non-maintained burrows. Even with maintenance, occupancy rates dropped from 31% during the first year to 8% during the third year post-installation. Maintenance or reinstallation of the entire burrow system appears to be crucial for longer-term use. The results of chi-squared goodness-of-fit tests showed no significant difference in nesting success (≥ 1 fledgling/pair) between natural and artificial burrows at either of the study sites (χ2 = 2.75 and 6.76, df = 3, p > 0.05). Of 120 burrowing owls raised in maintained artificial burrows, 70% were re-sighted occupying artificial burrows during subsequent breeding seasons, compared to 30% occupying natural burrows. Only 3% of these owls occupied their natal burrow during the first nesting season post-fledging. Of those owls that were re-sighted during two or more nesting seasons, almost half (48%) occupied different artificial burrows from one year to the next.

▼ The Eastern box turtle (Terrapene carolina carolina) is one of the most common reptiles in North America, but is soon to be threatened due to increased urbanization, disease, and the pet and food trades. In order to assist resource managers in choosing suitable sites for relocation studies, more information on the winter ecology of this species is necessary. We examined the temperature tolerance, microhabitat and degree of philopatry to hibernacula for juvenile and adult E. box turtles for two consecutive winters in Charles City Co, VA. The turtles were tracked via radio telemetry to record point locations during the active and inactive seasons. iButton data loggers were attached to each turtle to record temperature throughout winter. Vegetation data were collected and analyzed to determine if there are microhabitat differences between adult and juvenile turtles, and between occupied and random plots. Philopatry to wintering hibernacula was determined by measurements in the field and using ArcGIS. Adults had significantly higher minimum temperatures than juveniles during the first winter (P=0.027), but not during the second winter (P=0.327). Shrub and canopy cover were marginally higher for random plots than for occupied turtle hibernacula plots (P=0.066 and P=0.092, respectively); however there were no significant differences for any of the vegetation variables between adults and juveniles. Some of the turtles demonstrated
site fidelity of their hibernacula. The temperature data from this study suggests that juveniles may have poorer hibernacula selection and therefore lower minimum temperatures compared with adults, but this was not seen in our second season suggesting that juvenile turtles may learn to choose better hibernacula or to dig deeper. The difference in findings for the two winters could be attributed to illness by several of the turtles the first winter, by increased maturity in the juveniles the second winter or by the significant difference in ambient temperature for the two winters (P=0.0001). Juveniles do not differ from adults in microhabitat selection, therefore resource managers may not need to plan differently for juveniles and adults in relocation studies. We also conclude that both age groups of T. c. carolina exhibit
site fidelity of hibernacula.

▼ Impacts on aquatic biota residing near municipal wastewater treatment plant (MWWTP) outfalls have been documented globally. These impacts may be directly or indirectly associated with elevated contaminants such as nutrients, metals, suspended solids (SS), biochemical oxygen demanding matter (BOD), pharmaceuticals, and personal care products. A variety of effects have been well documented in the Grand River watershed of southern Ontario below the outfalls of the MWWTPs of the cities of Kitchener and Waterloo. Responses in wild fish have been reported at multiple levels of biological organization, ranging from altered gene expression to changes in fish communities, as well as changes in nutrient cycling within the aquatic food web. The most consistently observed effect has been high occurrences and severe cases of intersex (ova-testes) in the male rainbow darter (Etheostoma Caeruleum); this finding represents one of the worst examples of pollution-caused intersex reported anywhere in the world.
Primarily in response to the introduction of new effluent quality standards, the Region of Waterloo has invested millions of dollars to upgrade several of its MWWTPs including the facility servicing Kitchener, creating a unique opportunity to conduct a before-and-after study. The main objective of this thesis was to assess if treatment upgrades, which were targeted at conventional contaminants (i.e., ammonia, BOD, SS, and chloride), effectively remediated the responses previously reported in wild fish downstream of the MWWTP. To test this, historical, archived, and new data collections were used to assess changes at multiple levels of biological organization, including changes in nutrient cycling in the aquatic food web, reproductive effects in the male rainbow darter (e.g., intersex), and changes in fish community composition. For comparative purposes, responses in rainbow darter were also examined at numerous reference sites and below the smaller Waterloo MWWTP, which did not undergo any major upgrades during the study period.
The treatment upgrades at the Kitchener MWWTP (which included nitrifying activated sludge) improved the overall quality of the effluent; these improvements included reductions in nutrients (total ammonia), pharmaceuticals, and total estrogenicity (E2eq). In contrast, the Waterloo MWWTP had deteriorating effluent quality, with ammonia levels increasing over the course of the study. Changes in effluent quality at both the Kitchener and Waterloo MWWTPs were detected in the downstream aquatic food webs using stable isotope ratios (δ15N and δ13C). Patterns of δ15N in a primary consumer (benthic invertebrate) and a secondary consumer (rainbow darter) reflected the exposure to MWWTP effluents and changes in nutrient cycling in response to the changing effluent quality. A major reduction in intersex in the male rainbow darter below the Kitchener MWWTP outfall was also associated with the improvements in effluent quality. Rates of intersex were reduced by as much as 70% in the first year…

▼ We investigated White Ibis movements in an urban landscape by monitoring radio-tagged ibises (n=28) for one year. During the non-breeding season, 12 ibises were detected on >50% of surveys in urban areas and detected within three
kilometers, on average, of their original capture site; only seven were detected on <10% of surveys. Additionally, we radio-tagged 145 ibises at the Solid Waste Authority (SWA) and monitored for two years. Site fidelity decreased over time at SWA,
because of multiple factors including the installation of a waste combustor, which reduced garbage on the landfill. Our results show that “urbanized” ibises show high site fidelity to and spend most of their annual cycle in urban areas where they find
year-round resources. This is the first study on the movement patterns of a recently urbanized wading bird, allowing us to make predictions on the likely effects of urbanization on ibis behavior, ecology and health.

▼ The American White Ibis (Eudocimus albus) is a medium-sized wading bird commonly found in wetland habitats. Urbanization in wetland areas affects ibis as human modifications of the landscape reduce the overall extent of, fragment, or alter
the function of existing wetlands. Since wetland degradation, ibis are increasingly found in urban areas and take advantage of anthropogenic resources. I investigated changes in ibis movement ecology by tracking ibis captured in habitats representing an
urbanization gradient with GPS-GSM telemetry to define movement-based seasons and calculate seasonal ranges, site fidelity, and habitat use. Urban ibis non-breeding seasons were longer than average with small ranges, high site fidelity, and use of
several urban habitat classes compared to wild ibis. Their breeding seasons were shorter than average, but were otherwise similar to that of wild ibis, showing increased range size, decreased site fidelity, and use of agricultural and wetland
habitats.

▼ Information regarding spawning
site fidelity and movement patterns of the American horseshoe crab (
Limulus polyphemus) is crucial for developing effective conservation and management strategies on the correct spatial scale. To investigate the spatial ecology of American horseshoe crabs, 75 adult animals were tracked off the coast of Chatham, Cape Cod, MA from June 2010 to November 2011 using acoustic telemetry. Two groups of horseshoe crabs were tagged in spawning habitats (separated by ~2.0 km) with differing commercial harvesting pressure: one group inside Stage Harbor, where harvesting is permitted and the other within a Marine Protected Area (MPA) where harvesting is prohibited. Network analysis revealed that horseshoe crabs exhibited
fidelity to spawning habitat, but not necessarily to the habitat where they were initially tagged. Fifty-nine percent of horseshoe crabs tagged inside Stage Harbor were detected in the MPA and 13% of horseshoe crabs tagged in the MPA were detected inside Stage Harbor. Although horseshoe crabs were utilizing both spawning habitats, predictive modeling revealed little temporal overlap, suggesting that horseshoe crabs from the two spawning habitats represent local populations. Isolated and local populations are more susceptible to overexploitation than are larger populations with many migrants. To protect against overharvest and extinction of isolated and local populations, the correct identification of management units (MUs) must be a priority of fisheries managers. Horseshoe crab populations around Cape Cod, Massachusetts and New England behave differently, requiring the collection of more information so that conservation tools such as MUs or MPAs can be used most effectively.

▼ Artificial reefs are important management tools for red snapper, <i>Lutjanus campechanus</i>, fisheries in the Northern Gulf of Mexico. I deployed fish traps (0.97 m long; 0.64 m height; 175 x 115 mm funnel mouth size) to collect red snapper < 406 mm total length (TL) associated with pyramid-shaped artificial reef structures (3.7 m triangular base; 2.4 m height; 3.2 metric tons) to evaluate two reef distribution designs: (1) five closely-spaced pyramid units, and (2) five closely-spaced pyramids with two sets of two pyramids at 30.5, 61.0, and 91.5 m from the five pyramids. In 26 sampling trips, 927 red snapper were captured. Catch per unit effort (fish/hour) did not differ significantly among patterns (<i>P</i>= 0.396). Red snapper lengths differed significantly among patterns (<i>P</i>= 0.005), with the largest mean total length (235 mm, SE= 5.14) occurring at the pattern with 61.0-m spacing.

▼ Large scale, contemporary studies of genetic and demographics of a non-migratory, avian species in fragmented landscapes are scarce. Changing land-use and increased urbanization have drastically affected wildlife ecosystems and their
inhabitants via fragmentation. The paucity of genetic and demographic information for these species generates a gap in the study of population dynamics within these ecosystems, both among avian species, specifically, and all organisms, generally. Thus,
knowledge of the effects changing land-use has on population persistence is precarious at best. The philopatric, non-migratory, and sedentary nature of many of these species potentially limits genetic exchange, contributing to variable demographics, both
temporally and spatially, and purported population declines among fragmented, isolated landscapes. It has been proposed that translocation of individuals between populations may mitigate many of the negative effects of habitat fragmentation and
isolation. To date, numerous translocations of multiple species have occurred. However, few have investigated the associated demographic and genetic ramifications. Translocation may serve as an artificial means of dispersal and subsequently introduce
novel genes to isolated populations, potentially influencing demographic parameters (e.g., increasing fecundity). Furthermore, it is possible that translocation may operate as a conservation tool for restoring populations of declining and threatened
species and, ostensibly, may be of increasing value for biodiversity conservation. However, prior to instituting this technique as a widespread management tool, its efficacy warrants investigation using a native, ubiquitous species not considered
Endangered or Threatened. This dissertation addresses questions germane to translocation by integrating data from molecular lab techniques (microsatellite analysis) with field data collected through radio-location and spatial data present in a
geographical information system. I selected the Northern Bobwhite (Colinus virginianus), a non-migratory, gallinaceous species of low-mobility, as my model species. Northern Bobwhites are particularly sensitive to habitat fragmentation, have suffered
keen population declines during the past several decades, are a socio-economically important game bird, and exhibit a flexible mating regime that have demonstrated a strong propensity to respond rapidly to favorable habitat conditions. Therefore, using
Northern Bobwhites logically allows for application of results to numerous species necessitating early-succession ecosystems and exhibit similar life-history characteristics. My research objectives were to determine: the efficacy of translocation to an
isolated population of northern bobwhite, temporal and spatial limitations associated with translocation, and demographic disparities between translocated and resident bobwhites. I also examined genetic effects of translocation in northern bobwhites by:
determining genotypic differences among resident and translocated bobwhites prior…

▼ A small number of eastern north Pacific gray whales (Eschrichtius robustus), known as the Pacific Coastal Feeding Group (PCFG) forage during the summer months in the coastal waters between California and Alaska. Although several studies have analyzed the population structure of the PCFG, maternal learning and predator/prey dynamics have not been studied in detail. In this study I characterize fine scale habitat use and
site fidelity of eastern north Pacific gray whales in one foraging
site within the PCFG’s foraging range. I approach this study by examining
site fidelity to Clayoquot Sound in increasing detail at different time scales. Using the variability recorded in 17 field seasons of whale census surveys (1997-2013) as a proxy for fluctuations in prey, I suggest that the combination of physical properties of the study area and the life history characteristics of the primary prey species type enable Clayoquot Sound to persist as a foraging
site through time. The analysis of photographic identification data collected between 1998-2013 indicates that Clayoquot Sound is one
site within a larger foraging range, and that annual fluctuations in prey density are related to
site fidelity and residency time. By identifying cow/calf pairs using photographic identification data collected between 1998-2013 I characterize internal recruitment via maternal learning within Clayoquot Sound. A calf’s
site fidelity is related to its mother’s
site fidelity, but its residency time is related to annual fluctuations in prey density. In contrast, a cow’s residency time is not related to changes in prey, but increases in duration when accompanied by a calf. The interplay between fluctuations in prey productivity, and the age and gender of individuals, are the variables that most likely influence the distribution of PCFG whales intra- and inter-annually.

▼ Sotalia guianensis is listed as “Data Deficient” by the IUCN and as “Vulnerable” in Colombia. This study aimed to advance understanding of the ecology of this species and its habitats, and to provide information to conservation management in the southern Gulf of Morrosquillo, Colombia. Systematic boat-based surveys were conducted during 395 days in 2002-2006 and 2009-2010, following established routes. Total survey effort was 15,199 km in an area covering ~ 310km². Fine scale habitat use and behavioural modelling, photo-identification and mark-recapture techniques were used to analyze the ecological patterns for this species. The most recent abundance estimate of dolphins using the study area during dry and rainy seasons, varied from 225 (CV = 0.34; 95% CI: 118-426) to 232 (CV = 0.32; 95% CI: 127-246). Annual survival rate is estimated at 0.948 (95% CI = 0.876-0.980). Overall density was 0.74/km². Dolphins were present year-round in the whole study area. Results indicate that they do not use the study area uniformly and that the use of particular zones is related to eco-geographic variables. Dolphins showed a preference for waters greater than 3m in depth with a slightly increased preference for waters about 5m and 15-25m deep. The average group size was nine individuals. Some individuals show long-term high
site fidelity to some zones within the study
site boundaries. Even though the
site fidelity to feeding areas varied individually, all the individuals focused primarily on one specific area. Foraging was among one of the most predominant behaviours observed. The individual movements show that some dolphins use both bay and gulf waters. Dolphins show a range of surface cooperative foraging and feeding strategies. These cooperative behaviours were influenced by zone, group size and prey type. Based on these results an area of special management for the species will be created in Colombia.

▼ Fish can have complex life histories and use multiple habitats and resources throughout their life span. Consequently, their life histories are often poorly understood. The Atlantic Tarpon, Megalops atlanticus, is a large, typically migratory, elopomorph fish that is both ecologically and economically important. Atlantic Tarpon are under threat due to regional exploitation, loss of natal and juvenile habitat, poor water management, and offshore impacts. In addition, little is known about its lifelong habitat and resource use. In Chapter 1, I used stable isotope analysis of eye lens δ13C and δ15N values to explore patterns in trophic history and habitat use of 16 Atlantic Tarpon from West-Central Florida and Louisiana. The stable isotope chronologies showed 100% use of backcountry habitats during the early life history and an ontogenetic habitat shift to coastal waters at approximately 10 years of age and 140 cm total length. During the coastal phase Atlantic Tarpon displayed among-individual variability and within-individual consistency in basal resource use. In Chapter 2, mark-recapture data from a multi-year genetic tagging program were used to investigate survival and growth rates, ontogenetic habitat use, and migration of juvenile Atlantic Tarpon in Florida. The study found that juvenile Atlantic Tarpon take approximately 10 years to reach the length associated with maturity, and appear to have a high survival rate (~80%), possibly due to effective use of habitats with reduced competition and predation. Atlantic Tarpon underwent several ontogenetic habitat shifts throughout the juvenile phase. In addition, juvenile Atlantic Tarpon did not migrate long distances but instead showed fidelity to systems wherein only short movements were needed to shift habitat types. This work serves to fill critical gaps in our knowledge of Atlantic Tarpon life history and may aid in better management and conservation of the species.

▼ Migratory birds face threats throughout the annual cycle, and cumulative effects from linkages between the breeding and non-breeding grounds may impact species at the population level. Long-billed Curlews (Numenius americanus) are a migratory shorebird of conservation concern associated with grasslands that show breeding population declines at some regional and local scales. Curlews exhibit high site fidelity to breeding territories, but also spend approximately 75% of the year on the wintering grounds. Therefore, localized population declines could indicate localized threats, in the breeding or wintering grounds. However, little information is available regarding the spatial distribution of curlews on the wintering grounds, especially for Mexico. Furthermore, breeding ground studies which examine habitat selection and nest success in the context of predator and anthropogenic pressures are lacking. We add critical information that could help pinpoint conservation issues, including understanding limitations to nesting success and mapping spatial distribution and habitat use patterns during the non-breeding season. On the breeding grounds, we used a conditional logistic regression model to compare used nest-sites to available random sites and examine habitat selection within territories. We also studied correlates of nesting success with a generalized linear model for 128 curlew nests at five sites in the Intermountain West. During the non-breeding season, we attached satellite transmitters to track 21 curlews that bred in the Intermountain West and wintered in California and Mexico and quantified 95% home range and 50% core use size via utilization distributions created with dynamic Brownian Bridge Movement Models. For 14 individuals, we tracked multiple winter seasons and compared inter-annual site fidelity among winter areas, sexes, and habitat type with a Utilization Distribution Overlap Index. We documented four main wintering areas: (1) Central Valley of California, (2) the adjoining Imperial and Mexicali Valleys of California and Mexico, (3) the Chihuahuan Desert of inland Mexico, and (4) coastal areas of western Mexico and the Baja Peninsula. Curlews wintering in coastal areas had significantly smaller home ranges and fewer core use areas than inland-wintering curlews. Home ranges in the Central Valley were larger than other inland areas, and Central Valley females had larger home ranges than Central Valley males. Inter-annual site fidelity for wintering curlews was high, regardless of habitat type or sex. On the breeding grounds, curlews selected habitats for nest-sites with lower vegetation height and lower percent cover of grasses, bare ground, and shrubs than available sites. Nest-sites were six times more likely to have a cowpie within 50 cm than random sites. Higher probability of nest success was associated with higher curlew density in the nesting area, increasing percent cover of conspicuous objects such as cowpies within approximately two meters of the nest, and – surprisingly – higher densities of…

▼ In the present thesis I examined individual and sex-specific habitat use and site fidelity in the western barbastelle bat, Barbastella barbastellus, using data from a four-year monitoring in a Special Area of Conservation in Rhineland-Palatinate, Germany. The western barbastelle occurs in central and southern Europe from Portugal to the Caucasus, but is considered to be rare in large parts of its range. Up to now, long-term field studies to assess interannual site fidelity and the possible effects of intra- and interspecific competition have not been studied in this species. Nevertheless, such data provide important details to estimate the specific spatial requirements of its populations, which in turn can be incorporated in extended conservation actions. I used radio-telemetry, home range analyses und automated ultrasound detection to assess the relation between landscape elements and western barbastelle bats and their roosts. In addition, I estimated the degree of interspecific niche overlap with two selected forest-dwelling bat species, Bechstein's bat (Myotis bechsteinii) and the brown long-eared bat (Plecotus auritus). Intra- and interannual home range overlap analyses of female B. barbastellus revealed that fidelity to individual foraging grounds, i.e. a traditional use of particular sites, seems to effect the spatial distribution of home ranges more than intraspecific competition among communally roosting females. The results of a joint analysis of annual maternity roost selection and flight activities along commuting corridors highlight the necessity to protect roost complexes in conjunction with commuting corridors. Using radio-tracking data and an Euclidean distance approach I quantified the sex-specific and individual habitat use by female and male western barbastelle bats within their home ranges. My data indicated a partial sexual segregation in summer habitats. Females were found in deciduous forest patches and preferably foraged along linear elements within the forest. Males foraged closer to forest edges and in open habitats. Finally, I examined the resource partitioning between the western barbastelle bat and two syntopic bat species with a potential for interspecific competition due to similarities in foraging strategies, prey selection and roost preferences. Simultaneous radio-tracking of mixed-species pairs revealed a partial spatial separation of the three syntopic bat species along a gradient from the forest to edge habitats and open landscape. Long-eared bats were found close to open habitats which were avoided by the other two species. B. barbastellus preferred linear landscape elements (edge habitats) and forests, M. bechsteinii also preferred forest habitats. Only little overlap in terms of roost structure and tree species selection was found.

▼ Fires are natural distubances in many ecosystems, but humans have altered fire regimes throughout the world. The effect of fire on organisms, particularly birds, depend on the extent and regime of the fire and the species’ ecology.
The Azure-winged Magpie, Cyanopica cyanus is a cooperative breeder, and occurs in a disjunct distribution across much of Asia and in Iberia (Portugal and Spain). I conducted my study on the Northern Mongolian subspecies of Cyanopica cyanus in West Khentii, Northern Mongolia in 2009 and 2010. An anthropogenic fire that broke out in 2009 in the study area provided an opportunity to document the habitat use of the C. cyanus during the breeding seasons of 2009 and 2010, and to investigate the impacts of fire on the population dynamics of C. cyanus.
The home range of this colony of C. cyanus is ca. 1.233 km² and the colony utilises six main areas (ca. 0.532 km²) in their home range. C. cyanus utilises an area which has the densest Padus asiatica shrub stands within their home range, and which is also the richest in species utilised by the C. cyanus. This area was also the least affected by the fire amongst all six areas in 2009. C. cyanus seemed to have expanded their home range compared to pre-fire years, and a change in social structure was observed.
To address questions on population dynamics, four years worth of data was obtained from a previous study of the breeding biology of the same colony of C. cyanus. I found that over the four years: (1) colony size at the beginning of the breeding season did not change; (2) the number of hatched and fledged chicks declined significantly; (3) juvenile survival was constant, but adult survival declined slightly after the year of the major fire and following severe winter; (4) variable proportions of banded adults and juvenile were re-sighted from year to year, suggesting an open population; (5) between 26-67% of adults breed each year; (6) divorce rates in this colony of C. cyanus can be as high as 25%, and females still obtained new mates even though they had bred successfully the previous years; and (7) there was no association between breeding success and likelihood of returning in subsequent years.
At this stage, no conclusions can be made about the long-term impacts of fire on this colony. A longer-term study must be conducted in order to understand the population dynamics and ecology of the Northern Mongolian population of Cyanopica cyanus. The presence of cooperative breeding behaviour is expected to affect population structure and how this species reacts to environmental stochasticity and catastrophies.

underway using annual translocations of hatchlings from a donor site to the Assabet River National Wildlife Refuge. To increase first-year survivorship (which is typically low in turtles), 52% of translocated hatchlings were head-started (raised in
captivity for nine months post-hatching). We conducted mark-recapture efforts and used a Cormack-Jolly-Seber (CJS) analysis to estimate apparent survival of direct-released hatchlings (released shortly after hatching) and head-started hatchlings. We
examined post-release site fidelity and habitat selection by monitoring a subset of individuals through radio telemetry. We found that head-starts first year post-release apparent survival was nearly six times higher than direct-releases. Both
direct-releases and head-starts displayed site fidelity when there was a variety of habitat types available at the release site to select from.

▼ An individual-based model has been developed to simulate the evolution of traditional foraging strategies in a fluctuating environment. The parameters and procedures are based on observed behavior of Barnacle geese, Branta leucopsis, during spring staging off the coast of Helgeland, Norway. Within a spatially heterogeneous environment, goose movement is modeled according to state dependent
site selection decisions which maximize food intake. The aim of each individual is to optimize fitness (survival and reproduction) by gaining enough food (energy reserves) during three weeks of foraging to meet a threshold of energy necessary for successful reproduction. The geese return to the same islands each year, and on a daily basis choose unoccupied sites according to their rank in the population structured dominance hierarchy, memories of previously visited sites (tradition), past reproductive success, inherited genetic influence towards
site faithfulness and/or
site quality, and knowledge of the available biomass density. It is assumed that with each subsequent return to a specific location, increased familiarity of the area will benefit an individual through greater food acquisition by more efficient foraging practices. In the event of variable environmental conditions, geese are faced with a critical decision to return to previously visited sites or abandon tradition to explore for something better. It is shown that habitat quality plays an integral role in population dynamics. The evolution of foraging strategies which directly affects reproductive potential will inevitably determine the resilience of the population over time. Simulations of variable habitat availability were run and analyzed which serve to indicate the effect of certain strategies. It is shown that under environmental stasis the population stabilizes and traditional foraging is an optimal strategy. When faced with small perturbations to the foraging grounds, however, the population declines slightly but recovers quickly and generally maintains an affinity toward previously visited patches. Under significant environmental disturbance,
site fidelity reduces the chance for reproductive success and survival, and does not usually remain a prevalent behavior in the population. Overall, tradition is most beneficial when reality and expectation coincide, otherwise a compromising strategy must be employed to mitigate the interim. This modeling approach has the potential to reveal significant insight into the emergence of stable responses to environmental disturbance.

▼ Black rockfish (Sebastes melanops) recruit to shallow coastal habitats at four to six months of age. Habitats utilized include kelp and eelgrass beds, estuaries, and tidepools. Black rockfish are unique among Sebastes spp. in that they are found in tidepools as juveniles. The objective of this study was to determine if young-of-the-year black rockfish exhibit
site fidelity and homing behavior while inhabiting rocky intertidal areas. In addition, growth rates, recruitment, and use of rocky intertidal areas as nursery grounds were examined. This research was conducted off northern California at two rocky intertidal sites within Redwood National and State Parks during 2007 and 2008. To test for
site fidelity and homing behavior, fish were marked subcutaneously with unique color coded tags and displaced at distances ranging from 0 to 258 m from their original pool of capture.
Site fidelity was observed in 38 percent of all fish tagged. Homing behavior was noted in 61 percent of the fish recaptured. Homing behavior was observed at all displacement distances used. Fish displaced 258 m, however, displayed the weakest homing behavior. Mean growth in length ranged from 0.204 to 0.343 mm d-1 between years. Throughout the residence period, growth rates increased. Recruitment varied highly among sites and between years. In 2008, a 34-fold increase in recruitment strength was noted compared to 2007. Within each year the relative abundance of black rockfish was highest during the months of June and July, with peak abundance occurring between mid-June and early-July. Maximum residence time observed for a recaptured fish was 67 d. Length of residency was similar among sites and between years. Results indicate that young-of-the-year black rockfish display
site fidelity and homing behavior while inhabiting rocky intertidal areas. Furthermore, these findings strongly indicate that they use rocky intertidal areas as nursery grounds. This research provides important information for the management of rockfish and for future deliberations concerning marine protected areas off northern California.

▼ Hauling
site fidelity, movement patterns, and the proportion of harbor seals hauling out were examined for one year by radiotagging 12 seals in the Klamath River, California. Hauling
site fidelity was highest during the spring and summer months, with 42% of the tagged seals traveling from nearby hauling grounds to forage in the river. The majority of seasonal movements and dispersals originated during winter months, with subadult seals exhibiting a greater tendency for movement than adults. Seasonal movements coincided with the abundance of common prey items, pupping, breeding, and moulting activities. Tagged female seals made a significantly larger proportion of seasonal and local moves than males. Seals hauled out an average of 56.1 ?? 2.8% (standard error) of the days in April and 63.6 ?? 5.5% (S.E.) in May. Based on resightings, a minimum of 56.4 ?? 3.1% (S.E.) and 65.1 ?? 12.8% (S.E.) of the study area harbor seal population hauled out daily in April and May. The maximum recorded count corrected for the proportion of animals hauled out suggests that from 522 to 778 harbor seals were present in the study area at the peak of the season in May 1983.

▼ Studying the population parameters of marine mammals requires that individuals be identified both spatially and temporally. Traditionally, to identify individuals in the field, animals have been captured and physically marked with a unique feature, allowing the individual to be identified in the future. This method known as Capture-Mark-Recapture (CMR) has been widely utilized to analyze marine mammal populations. While quite effective, traditional CMR is invasive and poses potential risk for both animals and researches. More recently, with advanced technology and camera equipment a far less invasive and more cost effective method of Photo-identification based Mark Recapture has been developed (PMR). To assess the efficacy of computer aided matching software and the applicability of such software for future pinniped studies, a photographic based mark recapture study was conducted across the 2011-2014 harbor seal seasons using both manual and computer aided methods to determine if the Long Island, NY population display
site fidelity, in that they return to the same haul-out location over multiple seasons. Additionally, manual and computer methods were compared for accuracy and their potential use in future pinniped studies.

▼ Abstract
Climate change causes range expansions, but neither the population parameters nor the ecological mechanisms behind range expansions are well known. I studied population dynamics and demography of the great tit (Parus major) in northern Finland, close to the northern range margin of the species’ distribution. I further examined winter conditions, such as temperature, as limiting factors on winter site fidelity and survival of human-fed great tits. Temporal variation in the population growth rate was large, but indicated an overall increasing population size, which fits the current large scale increase in the north. Importantly, the study population was a sink (or pseudo-sink) in almost all years because of low adult survival and low local recruitment. Immigration formed 39–43% of the annual population growth rate indicating that the population is demographically dependent on immigration. The demography differs most from other great tit populations in terms of adult survival which is lower than estimates from more southern Europe. This difference may reflect the impact of more difficult winters. Results from the wintering population support this line of reasoning. Within-winter movement was lower during mid-winter (January to February) and decreased during cold periods. This pattern is probably linked to energy saving and predator escaping strategies during these demanding periods when energy expenditure is high and birds have limited daylight hours to forage. Site fidelity was lower for juveniles than adults within a winter, but not between winters. In addition, survival showed strong links to winter weather. There was temporal variation within winters, particularly when the winter was colder than usual. Survival of juveniles showed a stronger response to cold temperatures. When mean daily minimum temperatures declined below –15 C° degrees, survival started to decline. Low winter temperatures thus provide one explanation for the lower annual adult survival and the sink nature of the population. The results suggest that great tits suffer from the cold conditions of the north: higher mortality increases turnover allowing for strong immigration. Great tits should benefit from warming winters caused by climate change.

▼ Little is known about the breeding parameters and population structure of three Pennsylvania darters, the bluebreast darter, Etheostoma camurum, the spotted darter, E. maculatum, and the Tippecanoe darter, E. tippecanoe. All are Pennsylvania state threatened species, and they are considered threatened or endangered in several other states throughout their range. Although some limited breeding information is available from populations in other states, the timing and duration of spawning has not been documented for Pennsylvania populations of E. camurum and E. tippecanoe. Both species occupy disjunct riffle habitats in the Allegheny River system, with stable populations in French Creek. We have found an additional population for these species about 110 miles downstream in Deer Creek, Harmarville, PA. Through weekly catch-and-release sampling of this population, we have identified the peak breeding times and the duration of the breeding season for the Deer Creek populations of these two species. Observations of population peaks indicate possible seasonal migrations into spawning areas. Spawning terminated for both species when temperatures exceeded 23 C for several days. Turbid conditions may influence spawning
site occupation. Both species show strong
site fidelity within the spawning riffle irrespective of depth or flow. Genetic analysis using the mtDNA ND2 gene indicates little population structure for all three species across their entire range. Seven new
site records within the Allegheny River drainage suggest possible current gene flow through river-corridor migration and the possibility of the populations spreading from source population(s) in the Allegheny River to sink populations or seasonal breeding habitats in suitable tributaries. Population structure will be useful to conservation efforts by identifying the degree of population fragmentation between isolated populations. Breeding times and an understanding of factors that inhibit spawning will be a useful guide for ecologically responsible development of riparian areas, assisting with avoiding disturbances to important spawning areas during the breeding season.

▼ Living at the northern limits of its geographic range, the Florida manatee is particularly susceptible to cold stress-related mortality during the winter months, with most deaths occurring in the lower two-thirds of the state. Contributing to this cold stress susceptibility is the manatee's limited physiological and behavioral responses available when thermally stressed. While capable of migrating south in response to falling water temperatures, manatees must still find warm water when ambient river temperature drops below 20°C for more than a few days. This is in part due to the species low metabolic rate, limited capacity for thermogenesis, and limited ability to raise its metabolic rate. Prolonged exposure to cold temperatures may result in cold stress syndrome, which involves a number of potentially life-threatening, if not fatal physiological changes. Survival during the winter months is therefore, dependent upon the manatee's ability to balance basic physiological needs, primarily the need to forage and to obtain fresh water with the need to stay warm. When identifying which animals are most susceptible and where, analyses of statewide manatee mortality records from 1996 through 2011 (n = 823) indicated that, size and location matter. Medium to large-sized calves accounted for the majority of documented death from cold stress (46.6%), while subadults and small calves were the least represented size classes (14.3 % and 9.5%, respectively). Adults slightly outnumbered subadults (15.8%). Males outnumbered females in all size classes but gender differences were not statistically significant. With regards to location, two areas of the state, the southwest and central east coasts showed the highest incidents of cold stress-related mortality. Both are regions with no primary, natural warm-water springs and whose principal warm-water refugia are power plant effluents. Brevard County on the central east coast is the area most at risk during cold weather events accounting for more than 25% of all cold stress deaths statewide. Warm-water sites within this region are few and relatively underrepresented in the literature in an area well-studied in terms of manatee abundance and distribution relative to the operational power plant. Results from cold stress data analyses emphasize the importance of identifying and characterizing the physical attributes of both known and suspected secondary warm-sites used by manatees in this region for both long and short term protection of the species, and its critical habitat. Three locations within Brevard County identified as passive thermal basins (PTBs), and classified as secondary warm-water sites, have been documented supporting in excess of 100 manatees on numerous occasions, and during winters of varying severity. Unique in physical appearance, distance to forage, hydrology including thermal profiles, and when it was used by manatees, each
site challenged the accepted definitions and criteria of what constitutes an acceptable and appropriate warm-water
site. Through analyses…

▼ Black-fronted terns (Chlidonias albostriatus) are one of six endemic bird species that rely on New Zealand’s braided river ecosystems for breeding. Black-fronted terns have a small, declining population and are classified as globally endangered, primarily due to predation. Unlike many other endangered species in New Zealand, black-fronted terns cannot be translocated to offshore, predator-free islands as braided river habitat exists only on the mainland. Currently, predator control, at varying scales, and habitat enhancement are the primary management strategies for black-fronted terns, neither of which have proven more than locally effective at reversing current population declines. Effective black-fronted tern management is challenging, not only due to the dynamic and unpredictable nature of the braided river environment, but also the behaviour of the terns themselves. Black-fronted terns frequently change their breeding colony locations both within and between years. The current research aimed to investigate black-fronted tern colony dynamics, and determine the viability of social attractants as a tool for black-fronted tern conservation.
The location and size of black-fronted tern breeding colonies have been recorded from braided river bird surveys conducted over 13 years (2004-2015). Black-fronted terns are believed to have low site-fidelity due to the instability of their breeding habitat, small colony sizes and exposure to high predation rates. Two out of nine rivers analysed had colony distributions significantly different to random, a further two rivers had significant clustering of colony locations. Although the clustering was only significant in two rivers, the trend of clustering was consistent across all rivers analysed. There was no overall trend between colony size and the proximity of colonies in the previous or following seasons. Overall, these results support our a priori hypothesis of low site-fidelity in black-fronted terns, although, consistent clustering and spatial distribution trends suggest that they may exhibit greater fidelity to sites which remain suitable.
Social attractants, decoys and audio playback, were deployed at ten sites within nine Canterbury braided rivers in the 2016 breeding season. We found that the terns interacted significantly (P < 0.001) more with the social attractants compared to the control plots (social attractants absent). Differences in tern interactions observed could not be explained by the differences in habitat between the experimental plots. Nearest tern breeding was recorded for eight of the ten sites, with five of these nesting records occurring within 300 m of the experimental plots. These results suggest that social attraction has the potential for use in black-fronted tern conservation. However, further research is required to determine the most attractive social attractant set up and whether the attractants can influence tern breeding colony locations. Camera traps were also trialled, recording tern behaviour at the experimental plots. At this…

▼ Population declines of many migratory grassland bird populations in North America over the last several decades are thought to be the result of widespread loss of suitable breeding habitat. However, reclamation of surface mining operations in the midwestern and eastern United States has created breeding habitat for many grassland bird species. In western Pennsylvania, >35,000 ha of reclaimed surface mine grasslands are occupied by grasshopper sparrows (Ammodramus savannarum), Henslow’s sparrows (Ammodramus henslowii), and Savannah sparrows (Passerculus sandwichensis) in densities comparable to traditional grassland habitats. Henslow’s sparrows in Pennsylvania nest almost exclusively on reclaimed surface mines. Many species of grassland birds suffer increased nest predation on small (<100 ha) grasslands, and although successful reproduction of grassland sparrows has been documented on large (≥1,000) reclaimed mine grasslands, most reclaimed mine grasslands in Pennsylvania are small (≤100 ha) and nesting success has not been quantitatively described. To assess habitat suitability of reclaimed mine grasslands for nesting grassland sparrows, I investigated nest survival, nest
site selection, and
site fidelity of grasshopper, Henslow’s, and Savannah sparrows on four reclaimed surface mines in Clearfield and Clarion counties in western Pennsylvania, USA, in 2006 – 2007.
There were few clear and consistent patterns in nest
site selection, but, in general, all three species placed nests in areas with few shrubs, even though they frequently used shrubs as perches. Henslow’s sparrows placed nests in deeper litter than grasshopper and Savannah sparrows. Henslow’s and Savannah sparrows tended to avoid steep slopes more than grasshopper sparrows, and grasshopper and Henslow’s sparrows preferred areas where the view to the horizon was not steep. All three species avoided placing nests in areas with extensive bare ground.
Grasshopper and Henslow’s sparrow nests that were well concealed were less likely to fail than highly visible nests, and nests in areas with a deep litter layer were more likely to fail than nests in shallow litter. Savannah sparrow nests in areas with high visual obstruction by vegetation were less likely to fail than nests in areas with sparse and short vegetation. Daily probability of survival for grasshopper sparrow nests followed a quadratic seasonal trend where survival was greatest early and late in the breeding season. Survival of Savannah sparrow nests followed a decreasing linear seasonal trend. There was no seasonal trend in survival of Henslow’s sparrow nests. For all three species, nest survival was greater on days with rainfall events, and for nests of grasshopper and Henslow’s sparrows, but not Savannah sparrows, survival increased with increasing maximum daily temperatures. Overall nest success was 0.422 (95% CI = 0.362 – 0.493) for grasshopper sparrows, 0.369 (95% CI = 0.288 – 0.472) for Henslow’s sparrows, and 0.158 (95% CI = 0.066 – 0.379) for Savannah sparrows.

▼ Many populations of migratory cranes, geese and swans are increasing throughout Europe and North America. During migration, these birds congregate at staging sites, often located in landscapes with both wetlands and arable land. When foraging on newly sown or unharvested crops at staging sites they frequently cause harvest losses and thus conflicts between conservation and agricultural interests.
The aim of this thesis was to increase the knowledge about space use and foraging site selection of common cranes. Such knowledge is needed to guide management where and when crop damage might occur, and what damage preventive measures to implement under variable environmental conditions.
My studies are based on flock surveys and data derived from GPS transmitters in combination with field surveys of food availability and crop stages. I found that the Natura 2000 network fulfils its conservation intention for staging cranes along the flyway, but also that cranes spill over from Natura 2000 sites to surrounding arable land. This spillover may enhance the conflict between conservation of cranes and other bird species within Natura 2000 sites and agriculture. My studies further demonstrated that field selection by cranes was influenced by factors dependent on agricultural practices such as crop type, crop stage, time since harvest, food availability, but also human disturbance and distance to roost site. I further revealed an apparent mismatch between individual crane space use and current damage preventive management. To conclude, stubble fields with high availability of spilled grain close to the roost sites have the potential to steer cranes from unharvested crops and prevent crop damage. To mitigate conflicts between conservation and agriculture, ecological knowledge is needed, but also participatory involvement of stakeholders and international collaboration, such as a flyway management plan.

▼ Spinner dolphins (Stenella longirostris) were surveyed and photographed during the Spring/Summer of 2004-2007 in the Southern Tañon Strait region of the Philippines. Over 17,000 images of dorsal fins were taken during the study period for photoidentification purposes. The study area (approximately 100 Km2) is a popular site for cetacean-watching and more recently underwent oil exploration and drilling. A photographic database of 329 unique spinner dolphin dorsal fins was produced, and used to assess abundance and life history characteristics using DARWIN software. An overall abundance estimate (2004-2007) of 1118 individuals (990-1246 with a 95% confidence interval) was obtained using the POPAN feature of MARK software. These mark-recapture results reveal that approximately 28% (n= 92) of the identified individuals (n= 329) were present in the study area in at least two of the four study years. This information is necessary to gain a better understanding of the ecology and life history characteristics of small cetaceans in the Tafton Strait, and in the development of conservation, education, and habitat protection programs designed to protect these cetaceans from human impacts. This project is part of a long-term ongoing study of the small cetaceans in the Southern Tañon Strait.

▼ Minke whales, Balaenoptera acutorostrata, are the most abundant species of mysticetes in the North Atlantic Ocean; however, little is known about their site fidelity and population size in the Northwest Atlantic Ocean. Field work was conducted off the coast of Halifax, Nova Scotia Canada, mostly during the summer months of 1997 to 2000 and 2002 to 2005 with some field seasons starting as early as April and ending as late as October. During 218 days of boat-based surveys, 614 photographs (black and white film and digital) of minke whales were collected. All photographs were assigned a qualitative quality value (Q1-Q4, best to poor, respectively), and 321 were assigned Q3 or better. A total of 111 individuals were identified, although only 80 individuals had at least one high quality photograph (Q3 and higher). While many individuals were re-identified on the same day, only five individuals were resighted on separate days. Two individuals were resighted within the same year (up to 90 days apart), and three individuals were resighted in separate years (a little over three years apart). Additional photographs collected opportunistically in 2007 yielded two additional resightings of the same individual sighted four years earlier. A discovery curve that failed to reach an asymptote indicated that new individuals continued to enter the study area, thereby classifying the study area as open. Using the POPAN module available in SOCPROG 2.3, abundance was estimated to be 454 individuals (Jackknife s.e. = 398) with an estimated mortality rate of 26% per year (Jackknife s.e. = 27%). It is likely that permanent emigration and mark-loss account for much of this estimated mortality rate. Continued long term photo-identification within the study area is required to improve the abundance estimate and properly assess the degree of site fidelity. A lack of site fidelity could signify either unreliable or low density prey distribution, a limited sample size or a much larger home range than the study area. Therefore, expansion of both the study area and field effort is recommended.

▼ Birds likely have evolved behavioral adaptations that allow them to recognize suitable habitats to improve their chances of reproducing, and past studies indicate that reproductive failure may encourage dispersal. I investigated habitat selection patterns of 132 uniquely color-banded male Ovenbirds (Seiurus aurocapilla) at Hawk Mountain Sanctuary in eastern Pennsylvania to determine if territory quality could be estimated reliably using measures of occupancy. Furthermore, I tested whether returns and territory shifts were associated with prior reproductive success and bird age. I measured occupancy as the number of birds that occupied 30-m grid cells that covered two 18-ha study sites over the 12-year period and similarly calculated reproductive success rates within each grid cell. I measured first-year return rates and used GIS to calculate shift distances and overlap between consecutive territories. Despite variation in occupancy, reproductive success rates were generally high. Return rates also were high and birds rarely moved more than a territory width (68 m) during their lifetimes. There was no relationship between
site fidelity and past reproductive success, but shift distances decreased with age. My results differed from past studies that found a relationship between breeding dispersal and past reproductive success for species in a number of habitats. The lack of territory movements of Ovenbirds at Hawk Mountain Sanctuary may represent a general case for songbirds breeding in stable, high quality habitats, where sources of failure are infrequent and unpredictable. Birds may base dispersal decisions on more than personal breeding experience by monitoring the performance of neighbors to make broader assessments of habitat quality, which could explain why patterns of
fidelity differ among habitats based on quality and level of heterogeneity.

▼ We characterized habitat use, growth, and movement of early juvenile Atlantic sturgeon in Albemarle Sound, North Carolina through field work conducted in 1997 and 1998. Most of the Atlantic sturgeon encountered in the study were estimated to be age-1 fish. The presence of numerous age-1 Atlantic sturgeon near a historic spawning river (Roanoke River) suggests that these fish are likely native to the system. Recaptures of tagged Atlantic sturgeon allowed us to describe the growth of early juveniles using simultaneous analysis of length increment and length composition data. Growth of Atlantic sturgeon in Albemarle Sound was similar to growth rates observed in other systems, and suggests that Albemarle Sound serves as an adequate nursery habitat. Among telemetered individuals, we observed a preferred depth interval of 3.6 to 5.4 m. Additionally, the organic rich mud substrate type was used significantly more than expected under the null hypothesis of random movement.
Site-constrained movement was demonstrated by some fish. Occasional large catches of Atlantic sturgeon in our survey gear suggested that these fish may aggregate in the sound. Bycatch of Atlantic sturgeon by a commercial flounder gillnetter in eastern Albemarle Sound was dominated by fish within the expected age-2 size range. The impact of local gillnet fisheries on the Atlantic sturgeon population in the Roanoke River/Albemarle Sound system remains an important and unanswered question.

▼ Στην παρούσα διατριβή μελετήθηκε ο ρόλος της έλικας h44 του 18S rRNA του Saccharomyces cerevisiae επί διαφόρων παραμέτρων της πρωτεϊνικής σύνθεσης. Η μελέτη διεξήχθη με την βοήθεια των σημειακών μεταλλάξεων A1491G (rdn15) και U1495C (rdnhyg1), οι οποίες εντοπίζονται στην Α-θέση του ριβοσώματος. Η μετάλλαξη rdn15 επιδρά ήπια στον ρυθμό ανάπτυξης των κυττάρων ενώ τα rdn15 ριβοσώματα επιτελούν την πρωτεϊνοσύνθεση με αυξημένη ακρίβεια. Η έλλειψη σοβαρών επιπτώσεων παρουσία της rdn15 φανερώνει ότι το νουκλεοτίδιο 1491 δεν παίζει καθοριστικό ρόλο στην λειτουργία του ριβοσώματος. Τα κύτταρα ζύμης που φέρουν την μετάλλαξη rdnhyg1 αναπτύσσονται βραδύτερα από τα κύτταρα αγρίου τύπου, ενώ τα rdnhyg1 ριβοσώματα πρωτεϊνοσυνθέτουν με ελαφρώς αυξημένη συχνότητα λάθους. Η μετάλλαξη αυξάνει επίσης την συγγένεια της Α-θέσης του ριβοσώματος για το αμινοακυλο-tRNA και επιδρά αρνητικά στο στάδιο της μετατόπισης, χωρίς να επηρεάζει την ενεργότητα πεπτιδυλοτρανσφεράσης. Η επίδραση της μετάλλαξης rdnhyg1 επί διαφόρων παραμέτρων της πρωτεϊνοσύνθεσης δικαιολογεί την συντήρηση της U1495 κατά την εξέλιξη.
Η μετάλλαξη sup45-R2ts εντοπίζεται στο γονίδιο που κωδικοποιεί τον παράγοντα τερματισμού eRF1 και οδηγεί στην αντικατάσταση της προλίνης 86 από αλανίνη. Η μετάλλαξη δεν επηρεάζει τις περισσότερες από τις λειτουργίες του ριβοσώματος που εξετάστηκαν, αλλά μειώνει την μεταφραστική πιστότητα. Σε κύτταρα που φέρουν ταυτόχρονα την μετάλλαξη sup45-R2ts και την ριβοσωματική μετάλλαξη rdn15, η συχνότητα λάθους αυξάνεται σε βαθμό μεγαλύτερο από την αθροιστική επίδραση των δύο επιμέρους μεταλλάξεων, επιβεβαιώνοντας μια ιδιαίτερη αλληλεπίδραση του μεταλλαγμένου παράγοντα eRF1 με τα rdn15 ριβοσώματα, που, όπως προκύπτει, αντιστρέφει τον υπερακριβή χαρακτήρα των μεταλλαγμένων ριβοσωμάτων. Όταν η μετάλλαξη sup45-R2ts συνυπάρχει με την ριβοσωματική μετάλλαξη rdnhyg1 η συχνότητα λάθους δεν επηρεάζεται σημαντικά. Η rdnhyg1 φαίνεται να ελαχιστοποιεί την επίδραση του μεταλλαγμένου παράγοντα eRF1 ενισχύοντας την δράση GTPάσης του eRF3. Τα παραπάνω αποτελέσματα φανερώνουν επιπλέον ότι η sup45 δύναται να μεταβάλει τις ιδιότητας ορισμένων μεταλλάξεων κατά την ριβοσωματική λειτουργία.
Το στέλεχος που φέρει την μετάλλαξη rdn15 είναι πολύ ευαίσθητο έναντι της παρομομυκίνης αλλά και έναντι της τομπραμυκίνης, αν και σε μικρότερο βαθμό. Τα αποτελέσματα αυτά αποδίδονται στην ικανότητα της μετάλλαξης να αυξάνει την συγγένεια της Α-θέσης του ριβοσώματος για τα εν λόγω αντιβιοτικά. Αντίθετα, η μετάλλαξη rdn15 προσδίδει ανθεκτικότητα στην υγρομυκίνη, φανερώνοντας ότι ο τρόπος πρόσδεσης και δράσης του συγκεκριμένου αμινογλυκοζίτη διαφοροποιείται. Το στέλεχος που φέρει την μετάλλαξη rdnhyg1 είναι ανθεκτικό και στα τρία αντιβιοτικά σε σύγκριση με το αγρίου τύπου, φανερώνοντας ότι η U1495 είναι καθοριστική για την πρόσδεση των αμινογλυκοζιτών στο ριβόσωμα. Τα κύτταρα που φέρουν την εξωριβοσωματική μετάλλαξη sup45-R2ts είναι πιο ευαίσθητα από τα αντίστοιχα αγρίου τύπου έναντι και των τριών αμινογλυκοζιτών. Ωστόσο η μετάλλαξη sup45-R2ts, δεν επηρεάζει την ικανότητα των…
