Ecology of Elk on Department of Interior Lands in Southwest Wyoming

Between 2005 and 2010, we radio- collared 61 female elk (Cervus elaphus) on Fossil Butte National Monument and 12 female elk near Cokeville, Wyoming, slightly northwest of the Monument, all from the West Green River herd. We are using the 209,250 locations from these elk to identify seasonal distribution patterns, evaluate habitat use, and assess factors influencing the timing of migration.  ...

An investigation of aquatic invasive species in pristine sites in the Greater Yellowstone Area

Aquatic invasive species (AIS) are aquatic organisms that move into ecosystems beyond their natural, historic range and cause severe and irreversible damage to the habitats they invade. Most AIS arrive as a direct result of human activity, such as boating and angling. The threat of AIS introduction is especially high in the Greater Yellowstone Area, as humans from all over the world come to...

Impacts of climate change on habitat quality: plant phenology interactions with animal use and fitness

Weather and climate impact terrestrial wildlife habitat through their influences on plant productivity. Plant phenology – the timing of life-history events such as green-up, flowering and senescence – provides one indicator of the timing and magnitude of productivity. Changes and variability in plant phenology in space and time are indicators of habitat quality, which is a driver of fitness...
