Impacts Of A Mixed Ungulate Community On Aspen Forests: From Landscape To Leaf, Aaron C. Rhodes
Impacts Of A Mixed Ungulate Community On Aspen Forests: From Landscape To Leaf, Aaron C. Rhodes
Theses and Dissertations
This dissertation explores the differential effects of an ungulate community (cattle, mule deer, and American elk) on aspen (Populus tremuloides) regeneration pre- and post-fire disturbance. It's first chapter examines the differential effects of cattle, mule deer, and American elk on aspen regeneration across variable topography, climate and forest type; aspen dominant to conifer dominant subalpine forests. We found that each ungulate species, if sufficiently numerous, can cause aspen regeneration failure. Also, high elevation, southern aspect and high winter snow pack increase resilience to ungulate herbivory. Chapter two compares the efficacy of four methods of estimating ungulate impact on …
Beyond Capture: Development And Validation Of A Method To Assess Body Condition In Mule Deer (Odocoileus Hemionus) Using Camera Traps, Rachel A. Smiley 6820420
Beyond Capture: Development And Validation Of A Method To Assess Body Condition In Mule Deer (Odocoileus Hemionus) Using Camera Traps, Rachel A. Smiley 6820420
University Scholar Projects
Advances in technology and availability associated with camera traps have resulted in a rapid rise in their use to monitor wildlife distribution, abundance, and behavior. We focus on assessing body condition, a new application of camera traps. Body condition indices must relate to the percent body fat if they are to be useful. To acquire measurements of body fat, most body condition indices require capture or mortality of animals to estimate, which has limitations when applied to free-ranging animals. We developed a non-invasive, visual body condition index (VBCI) to assess body condition of mule deer that can be applied …

Effects Of Changing Environments On Survival Of A Widely Distributed Ungulate, S Andrew Sims
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
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 …
