Nonlinear effects of group size on the success of wolves hunting elk
Daniel R. MacNulty, Douglas W. Smith, L. David Mech, John A. Vucetich, Craig Packer
2012, Behavioral Ecology (23) 75-82
Despite the popular view that social predators live in groups because group hunting facilitates prey capture, the apparent tendency for hunting success to peak at small group sizes suggests that the formation of large groups is unrelated to prey capture. Few empirical studies, however, have tested for nonlinear relationships between...
Bird-habitat relationships in interior Columbia Basin shrubsteppe
S.L. Earnst, A.L. Holmes
2012, The Condor (114) 15-29
Vegetation structure is considered an important habitat feature structuring avian communities. In the sagebrush biome, both remotely-sensed and field-acquired measures of big sagebrush (Artemisia tridentata) cover have proven valuable in understanding avian abundance. Differences in structure between the exotic annual cheatgrass (Bromus tectorum) and native bunchgrasses are also expected to...
