All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Rapid climate change presents humanity with a number of big problems.

Ecologists have collected solid evidence that climate change has already begun to affect the living things around us and the ecosystems humans depend on. Unfortunately, predicting the future effects of climate change on life on earth is not easy. We focused on three research goals as part of an effort to improve our ability to predict how plants and …

Behavioral Response Of Desert Bighorn Sheep To Human Harassment: A Comparison Of Disturbed And Undisturbed Populations, Michael M. King
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Desert bighorn sheep (Ovis canadensis nelsoni) response to human disturbance was evaluated in southeastern Utah from 1981-1983. Bighorn response was compared between the Red Canyon area, an area with relatively high levels of human disturbance, and the White Canyon area, an area with relatively low levels of human disturbance. Bighorn were deliberately harassed by vehicles and hikers and immediate response and distance fled were recorded. When bighorn remained in the presence of the harassing stimuli, actual time spent in and proportion of animals engaged in various behaviors were recorded to determine group wariness and activity budgets under harassed …
