摘要: A stochastic predator-prey model was developed to predict the probable consequences of wolf recovery in Yellowstone National Park and adjacent areas Wyoming. Abundant prey enhances probability that can be accomplished. Wolves are expected reduce abundance park by 10–30%, with elk as principal species. PrEdation wolves should dampen substantial fluctuations ungulates undergo due variations climate. Impacts on native will depend upon management practices. For example, culling leave poaching within total number park, increase ungulates. Hunting outside boundaries Montana is compatible recovery. This possible because there no hunting rates northern herd not high, compensatory mortality natality permit moderate levels well prEdation. Greater conflicts predicted for Jackson Wyoming where intensity greater. Wolf need cull Grand Teton Park.
