Long term studies in a region show that the annual density of nesting raptors closely tracks annual variation of the local field mouse population density. When field mice are abundant the density of nesting raptors is high, and when the field mice population is low few raptors nest in the area. What type of response are the raptors exhibiting in responding to changes in prey abundance?

As the dry season approaches in an arid landscape in Africa, river levels start to decrease, which leads to a situation where there are only a few pools of water that attract land animals that need to drink.
Crocodiles in the river tend to congregate in these pools where water is still reasonably deep and where potential prey often come to drink. The behavior of the crocodiles is representative of...
