Effects Of Wildfires On Rattlesnake (Crotalus Oreganus) Growth And Movement In Washington State, Joseph Chase Jan 2017

Effects Of Wildfires On Rattlesnake (Crotalus Oreganus) Growth And Movement In Washington State, Joseph Chase

All Master's Theses

Fire is a dominant force in the Pacific Northwest that shapes ecosystems and influences wildlife, yet little is known of its effects on local predators. Northern Pacific rattlesnakes (Crotalus oreganus) comprise an excellent model to investigate how fire may influence wildlife because they are important predators that contribute to controlling prey populations, but are also unable to readily escape from wildfires. We developed a novel technique to assess growth rates of rattlesnakes by using digital photography to analyze differences in widths of their rattle segments laid down over time. We compared growth rates of rattlesnakes in habitats that …

Home Range Analysis Of The Montane Vole, Don Rogers Toews

All Master's Theses

This study on Microtus montanus was divided into three major sections: 1) An examination of nests, burrows, and runways, 2) A comparison of two methods of home range analysis--live trapping and radio-isotope tracing, and 3) A comparison of the home range of Microtus montanus with other species of Microtus as published in the literature.
