Effects Of Changing Environments On Survival Of A Widely Distributed Ungulate, S Andrew Sims
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Wildlife species distributed over large areas of land inhabiting varying environments are experiencing shifts in their home ranges due to human expansion and climate change. As these species home ranges shifts out of familiar, critical habitat they are forced to interact with novel environments, which in turn affects the species population demographics. In order to manage and conserve these species accordingly, specifically in a time of large-scale change, it is imperative that we add to current understandings of how they interact with various environments. Furthermore, frequently generating short-term predictions of demographic drivers will allow for conservation and management insight that …

An Evaluation Of Deer And Pronghorn Surveys In South Dakota, Kristopher W. Cudmore
Electronic Theses and Dissertations
To properly manage white-tailed deer (Odocoileus virginianus), mule deer (Odocoileus hemionus), and the American pronghorn antelope (Antilocapridae americana), wildlife managers must identify population perimeters, sample size, age and sex ratios of these three species. The primary objective of this study was to evaluate age and sex ratios and determine a minimum sample size for each study area for all deer species and pronghorn, in addition to deriving a methodology and population estimate for white-tailed deer in the Black Hills. Sample size needed for both species of deer and pronghorn ranged from 60-70 groups of does. Age ratios calculated from daylight …
