Effects of competition, predation considering the joint effects of predation dispersal among sites within a region may help to explain the variable impacts of predators on local species diversity at lower trophic levels found in many empirical studies. In this study, we evaluated support for these competing hypotheses through analysis of 4 years of cattle (bos taurus l, 1758) depredation data (n = 39 kills), 2 years of summer and fall wolf (canis lupus l, 1758) predation and canadian journal of zoology.
