- W2024584338 abstract "Charnov (1976) provided an optimal-time solution, whereby a predator leaves a patch as the rate of prey capture decreases. In his work and most subsequent theoretical and experimental studies, a single animal is considered the optimizer of the time investment. Using the principles of game theory, we have presented here a simple model of optimal time investment in the presence of exploitative competition, in which resource patches are continuously supplied. The model led to several predictions. (1) The optimal time investment, x*, is uniquely determined as a function of the parameters. (2) This optimum is larger when the number of consumers is larger, when the resource supply rate is lower, when the resource extinction rate is higher, when the handling time is longer, when the searching efficiency is lower, or when the number of consumers and the resource supply rate are both lower but their ratio is constant. (3) The parameter space is separated into two regions: a competitive region, where x$ mainly depends on competitive intensity, and a noncompetitive region, where x* mainly depends on the handling time. The one-parameter dependence is more intense when the relative extinction rate of the resource is lower. The optimal time investment in a cooperative case was shown to exceed that in a competitive case." @default.
