Optimal foraging theory definition biology
WebAccording to optimal foraging theory (Stephens and Krebs, 1986), the ability of predators to aggregate in patches of high prey density is a critical element in determining how effective the predator can be at limiting prey populations.

Like all optimal foraging models, the optimal diet model has a mathematical description: E is the amount of energy a prey item provides; h is the time it takes for a predator to consume the prey, the search and handling time. The profitability of a prey item is therefore defined as E / h.
WebMar 22, 2014 · A series of optimal foraging theories have been developed in line with this objective [ 3 ]. By assuming that animal activities are optimized to maximize the rate of net energy gain, optimal foraging theories provide testable hypotheses as well as bases for interpreting complex animal behaviour [ 3, 4 ]. Optimal foraging theory (OFT) is a behavioral ecology model that helps predict how an animal behaves when searching for food. Although obtaining food provides the animal with energy, searching for and capturing the food require both energy and time. To maximize fitness, an animal adopts a foraging strategy that provides the most benefit (energy) for the lowest cost, maximizing the ne…
