Carbon and Nitrogen Dynamics in Elk Winter Ranges

Aspen Stand Conditions on Elk Winter Ranges in the Northern Yellowstone Ecosystem, USA

1 Corresponding author: [email protected]; 715-346-4098 2 [email protected]; 541-737-3056 ABSTRACT: Aspen (Populus tremuloides) stands inside and outside Yellowstone National Park (YNP), Wyoming, USA, were compared to test whether the lack of overstory aspen recruitment observed in YNP extended to winter ranges of elk (Cervus elaphus) in adjacent national forests. Remote sensing and fi...

Winter feeding of elk in the Greater Yellowstone Ecosystem and its effects on disease dynamics

Providing food to wildlife during periods when natural food is limited results in aggregations that may facilitate disease transmission. This is exemplified in western Wyoming where institutional feeding over the past century has aimed to mitigate wildlife-livestock conflict and minimize winter mortality of elk (Cervus canadensis). Here we review research across 23 winter feedgrounds where the ...

Modeling soil microbial dynamics in carbon and nitrogen cycling

Goal To determine the relative importance of different mechanisms that influence carbon loss from soil under variable soil-moisture conditions. The soil contains more carbon than the atmosphere and plants combined (Scurlock and Hall 1998). This carbon is important for maintaining soil fertility, controlling erosion, and the long-term storage of carbon that could be released into the atmosphere....
