The change in an individual predator's rate of exploitation of prey as a result of a change in prey density.

patch dynamics

Biology; Biogeography

The change in the distribution of habitat patches in a landscape generated by patterns of disturbance and subsequent patterns of vegetative succession.

The death rate of young after fledging, calculated from the following: the fates of young birds after fledging (or hatching in the case of precocial young), when these fates can be observed directly; ...

detection distance
