Complexity Increases Predictability in Allometrically Constrained Food Webs

Creator:: Iles, Alison C. and Novak, Mark
Abstract:: All ecosystems are subjected to chronic disturbances, such as harvest, pollution, and climate change. The capacity to forecast how species respond to such press perturbations is limited by our imprecise knowledge of pairwise species interaction strengths and the many direct and indirect pathways along which perturbations can propagate between species....

Dental microwear textures across cheek teeth in canids: Implications for dietary studies of extant and extinct canids

Creator:: Tanis, Brian P., DeSantis, Larisa R. G., and Terry, Rebecca C.
Abstract:: Dental microwear texture analysis (DMTA) has been instrumental in reconstructing dietary ecology of extinct and extant carnivorans. Current sampling methods for canids focus on lower second molars (m2), where the grinding of flesh and bone captures dental microwear indicative of diet. However, dental microwear on other biomechanically analogous grinding facets...

Early to Late Holocene Surface Exposure Ages From Two Marine-Terminating Outlet Glaciers in Northwest Greenland

Creator:: Reusche, Melissa M., Marcott, Shaun A., Ceperley, Elizabeth G., Barth, Aaron M., Brook, Edward J., Mix, Alan C., and Caffee, Marc W.
Abstract:: Terrestrial chronologies from southern Greenland provide a detailed deglacial history of the Greenland Ice Sheet (GIS). The northern GIS margin history, however, is less established. Here we present surface exposure ages from moraines associated with two large outlet glaciers, Petermann and Humboldt, in the northwestern sector of the GIS. These...

Investigating Calving Areas for Rocky Mountain Elk on the Plumas National Forest: Implications for Land Management

Creator:: Marshall, Abigail C.
Abstract:: Sustainable elk (Cervus canadensis) habitat management on U.S. Forest Service (USFS) lands involves a complex relationship between management practices and ecological processes. A relatively novel Rocky Mountain elk population (Cervus canadensis nelsoni) on the Plumas National Forest (PNF) in northeastern California became established in the early 2000s, but there is...

Ecological Monitoring of Vascular Plant Resources at the Governor Tom McCall Preserve at Rowena Plateau: Initiation of Long-term Studies for Management.

Creator:: Meinke, Robert J. and Magee, Teresa K.
Abstract:: The bluffs and plateaus of the eastern Columbia River are floristically rich and ecologically intricate. A previous descriptive study of the unique scabland vegetation on the Gov. Tom McCall Preserve at Rowena Plateau in Oregon included delineation of several distinct or intergrading native and non-native vegetation units. In this study...
