摘要: Although there is ample evidence for the generality of foraging and predation trade-offs in aquatic systems, its application to terrestrial systems less comprehensive. In this review, meta-analysis was used analyze experiments on giving-up-densities evaluate overall magnitude risk behavior experimental conditions mediating effect. Results indicate a large significant decrease effort as consequence increased risk. Whether were conducted under natural or artificial produced no change effect had foraging. Odor live predators correlate weaker nonsignificant effects compared habitat characteristics. The suggests that strongly dependent type being utilized.
