- Library Collection RecordThe roosting habits and ecology of Northern Bobwhite (Colinus virginianus) are not well documented. Previous researchers have reported that bobwhites roost in open grassland with herbaceous…Publication Date 2016
- Library Collection RecordPrairie dog colonies can have a large impact on plant species composition and rangeland production through direct consumption and by clipping vegetation to increase predator detection. Vegetation…Publication Date 2016
