Landscape genetics and CWD in white-tailed deer
… plans. In this investigation, we also used landscape genetics to examine the effect of landscape features on dispersal and population boundaries of white-tailed deer. An awareness of how the landscape affects animal movement and genetic exchange between populations contributes to our …

Landscape genetics of northern bobwhite and swamp rabbits in Illinois
… habitat loss and fragmentation in agricultural landscapes. Population declines for the bobwhite and the paucity of information regarding swamp rabbit prevalence add uncertainty to their potential for persistence in Illinois. Research has indicated that these 2 species rarely disperse long …

Landscape Genetics of the Marbled Salamander (Ambystoma Opacum) at Mammoth Cave National Park
… or endangered species. Here I present a landscape genetics study on marbled salamanders (Ambystoma opacum) in highly connected forested habitat at Mammoth Cave National Park. This investigation of gene flow among ponds within a mostly continuous landscape provides data that can be …

Habitat modification and gene flow in Saimiri oerstedii: Landscape genetics, intraspecific molecular systematics, and conservation
… effects of increased habitat modification and landscape change on population persistence and processes of divergence. Recent studies in landscape ecology suggest that our understanding of dispersal in a heterogeneous landscape will improve by explicitly considering the heterogeneity of matrix …

Malleefowl and anthropogenic change: an integrated analysis of population trends, landscape genetics and movement ecology
… were to assess population trends, investigate landscape genetics, study movement patterns and the influence of habitat variables. These objectives were addressed through a multidisciplinary approach to study discrete Malleefowl populations at study sites located on the Eyre Peninsula in South …

Conservation of a fossorial grassland species (Geomys bursarius) through understanding niche reduction, landscape genetics, and phylogenetics
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2024-03-01 without embargo terms

The Importance of Multiple Study Areas in Landscape Genetics: The American Black Bear in the Rocky Mountains
… their distribution. I used individual-based landscape genetics analyses in 12 study areas in western Montana and northern Idaho to assess the influence of landscape features on gene flow among American black bears (Ursus americanus). I compared the influence of landscape features among the …

A seascape genetics approach to exploring the phylogeographic response of marine fishes to late Quaternary climate change
… distributions. In terrestrial studies, a landscape genetics approach is often used to explain how geographic, ecological and evolutionary processes interact to structure spatial genetic variation across populations, but these approaches have only begun to be used in marine ecosystems. This …

Environmental Drivers of Dispersal in Black-and-White Ruffed Lemurs (<i>Varecia variegata</i>)
… data– are more common.</p> <p>The field of landscape genetics enables researchers to combine population genetic data with landscape information to explicitly evaluate the influence of both local and intervening environmental variables in driving dispersal. To date, research in primate …

Use of environmental variables to infer gene flow and population structure in the gopher tortoise (Gopherus polyphemus) and predict the seroprevalence of an emerging infectious disease
… Here, I use novel approaches from the field of landscape genetics to combine spatial genetic data with landscape data at both regional and local spatial scales to explore natural and anthropogenic landscape features that shape population structure and gene flow in a federally threatened reptile, …

Visualising continuous intra-landscape isolation for brushtail possums using least-cost modelling
… that visualise how isolation changes across a landscape in order to enable better invasive species risk assessments to be undertaken. Many methods exist for quantifying isolation using a binary patch-matrix landscape representation. However, when species and landscape characteristics require …

A spatial risk assessment of hemorrhagic disease in cattle in Illinois from 2005 to 2011
… and limiting exposure to wild deer. Utilizing a landscape epidemiology approach, we analyzed the combined effect of rainfall, temperature, forest patterns, deer density and soil on the risk of HD in cattle in Illinois from 2005-2011 at the county level. Data regarding suspected disease in …

Conserving Connectivity: Ecological Determinants of Gene Flow in Plants at the Landscape Scale
… there is an increasing need to manage landscapes in a way that maintains gene flow among previously continuous populations. This requires a detailed understanding of the scale of gene flow in nature and of how aspects of the landscape support or inhibit movement. In plants, gene flow …

NORTHERN RIVER OTTER POPULATION ASSESSMENT AND CONNECTIVITY IN WESTERN MONTANA
… or how populations are structured on the landscape. Otters are sensitive to degradation of aquatic systems, mostly due to loss of prey. This is evident in the Upper Clark Fork River (UCFR), Montana, which has been polluted from decades of mining activity. My objectives for this project …
