Colorado River Cutthroat Trout Habitat Resistance And Resilience To Climate Change, Kate H. Olsen
Colorado River Cutthroat Trout Habitat Resistance And Resilience To Climate Change, Kate H. Olsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Government agencies and private organizations spend large amounts of public money attempting to return ecosystems to a more natural state, which have often been harmed or even destroyed as a result of modern development. Colorado River cutthroat trout, Oncorhyncus clarki pleuriticus, are a subspecies of cutthroat trout. Cutthroat trout live in the Rocky Mountains of the western United States. The population of this particular subspecies has been severely reduced by human actions, and currently only 12% of its historic populations still exist. To improve the condition of cutthroat trout, fisheries professionals and biologists are working to restore natural populations. …
Modeling Usa Stream Temperatures For Stream Biodiversity And Climate Change Assessments, Ryan A. Hill
Modeling Usa Stream Temperatures For Stream Biodiversity And Climate Change Assessments, Ryan A. Hill
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Stream temperature in one of the most biologically important aspects of water quality, but we lack temperature information for the vast majority of streams within the USA. Stream temperature can be influenced by several types of landscape and waterway alteration including upstream urbanization, agriculture, and reservoir releases. Stream temperatures are also expected to be affected by climate change over the next
century. We need to know how stream temperatures vary naturally, how they are influenced by human activity, and how they will respond to climate changes to effectively manage stream ecosystems. I used data from several thousand streams within the …
Vitals Rates And Seasonal Movements Of Two Isolated Greater Sage-Grouse Populations In Utah's West Desert, Jason D. Robinson, Terry A. Messmer
Vitals Rates And Seasonal Movements Of Two Isolated Greater Sage-Grouse Populations In Utah's West Desert, Jason D. Robinson, Terry A. Messmer
Human–Wildlife Interactions
Declines in greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) populations in Utah over the last century parallel range-wide trends. However, little is known about the ecology of sage-grouse populations that inhabit Utah’s naturally fragmented habitats. Utah’s West Desert sage-grouse populations occupy sagebrush (Artemisia spp.) habitats that are geographically separated by the Great Salt Lake, and largely confined to the Sheeprock and Deep Creek watersheds. From 2005 to 2006, we monitored sage-grouse that were radio-collared in each watershed to determine the factors affecting the vital rates in these isolated populations. Livestock grazing by domestic cattle was the dominate land use, …
