A predator-prey model with overlapping generations is proposed, assuming delayed population growth and a new estimate of the number of predators starving to death. Differences among simulation results caused by manipulation of values of coefficients

Hungry sticklebacks, Gasterosteus aculeatus , preferentially attacked the densest region of a swarm of water fleas, but with decreasing attack readiness they increasingly preferred less dense regions. Such a hunger dependent change in feeding prefere

ACCORDING to the principle of natural selection, each individual animal is assumed to maximise its inclusive fitness1. Thus, observed behaviour patterns should result from optimisation processes involving costs and benefits measured in a currency of

Optimal foraging theory has dealt with the following questions independently: (1) On what prey types should an individual predator feed (optimal diet)? (2) How long should a predator stay in each patch if prey is patchily distributed (optimal allocat
