Differences in seasonal habitat use by female Rio Grande wild turkeys (Meleagris gallopavo intermedia) were evaluated on two study sites (Encino and Laureles Divisions of the King Ranch) in south Texas. Wild turkeys have been important components of the Rio Grande Plains and Low…

Visitors to Yellowstone National Park are drawn to the spectacular scenery, unique thermal features, and the large numbers of wild animals easily observed in their natural habitat. The thoughtful visitor to the park cannot help but be captivated by the unparalleled breadth of sc…
The ability of animal populations to compensate for harvest mortality provides the basis for sustainable harvesting. Coyote populations are resilient to exploitation, but the underlying mechanisms of compensation and how they inter-relate are not fully understood. Moreover, defi…
In Lake Oahe, a large mainstem Missouri river reservoir that spans 375 river kilometers in central North and South Dakota, naturalized Rainbow Smelt are the primary forage species for a regionally important Walleye Sander vitreus fishery. Walleye condition in Lake Oahe is highly…
Infectious respiratory disease has long been identified as the cause of bighorn sheep (Ovis canadensis) historical declines and extirpations, and Mycoplasma ovipneumoniae (Movi) is the primary pathogen inducing disease and mortality. Population-level effects of pneumonia events …
There is widespread demand for the development of a pastoral training program for lay pastors in the province of Cebu, Philippines. Lay pastors, by definition, have no formal theological education. This ministerial situation in Cebu has created the need to establish informal the…
North American bat species face a range of environmental stressors which have negatively impacted recovery of the endangered Indiana bat (Myotis sodalis) and led to inclusion of the northern long-eared bat (Myotis septentrionalis) as a federally threatened species. Historic thre…
The southern portion of the Prairie Pothole Region (PPR), including the Des Moines Lobe of northwest and north-central Iowa, is predicted to become increasingly important to breeding waterfowl as climatic changes drive a southeastward shift in wetland distribution. The history o…
The integration of genetic and environmental information can help wildlife managers better understand the factors affecting a species’ population structure and their response to disturbance. This thesis uses genetic techniques to assess the broad and fine scale population struct…
Since the early 1900s, elk (Cervus canadensis nelsoni) populations throughout much of the Rocky Mountain west have expanded in size and geographic range. Simultaneously, humans and agriculture production have encroached into natural elk habitat, and human-elk conflicts have aris…
Investigating individual-based habitat settlement and space use decisions (i.e., how individuals distribute themselves across a landscape) is a central theme in ecology, with potential consequences for fitness (e.g., survival, reproduction). Among mammals, habitat selection and …
Effective measures for the conservation of biodiversity require an understanding of the extent and distribution of diversity within and among species. Studies focussed on providing such understanding can benefit from increasingly powerful and accessible genome-wide data. Overexp…
Translocations have the potential to aim conservation efforts as well as to reduce mortality caused by human activities. Eastern diamondback rattlesnakes (Crotalus adamanteus, EDB) have a limited ability to adapt to habitat loss and fragmentation due to the species’ slow life hi…
The capacity for human-wildlife conflict is increasing as anthropogenic development continues to expand across the planet. Many species of wildlife experience adverse anthropogenic effects on their behavior, life history, and ecology. Behavioral changes often manifest as shifts …
Stream connectivity is necessary for the persistence and viability of migratory fish populations. However, many of the world’s river contain dams, creating barriers or obstacles that can impede movement. Fishways have been constructed to provide passage for migratory fishes, but…
Southern Flounder (Paralichthys lethostigma) is an economically important species that uses habitats across salinity gradients along the Atlantic Ocean and Gulf of Mexico. During winter, adults spawn offshore, and larvae migrate to estuaries. During spring, larvae settle, grow, …
