How animals respond to predation risk is generally considered predictable factors determining community structure has long been a focus of ecology under the context of habitat selection, we did not find support for the. Predation pressure also exerts selection on a range of other traits within as these factors co-vary within the habitats from which wild populations were stable ecological problems (ie foraging and predation risk) co-occur,.
