Optimal foraging definition
WebUniversity of California, Santa Cruz WebOptimality models are used to predict optimal behavior (ex. time spent foraging). To make predictions about optimal behavior, cost-benefit graphs are used to visualize the optimality model (see Fig 1). Optimality occurs at the point in which the difference between benefits and costs for obtaining a currency via a particular behavior is maximized.

WebMar 22, 2014 · According to this definition, each past foraging dive in the bout has the same influence on the calculation of prey capture rates, regardless of how recently the dive occurred. This is the simplest form for how animals may process past experiences to predict the total, long-term prey capture rate in the future [ 19 ].
