WebDec 14, 2011 · Since several decades, optimal diet theory (ODT) has been used to explain prey preference. ODT predicts that predators should hunt for prey items that generate high energetic values per unit of handling time (Emlen 1966, MacArthur and Pianka 1966, Schoener 1971, Pyke et al. 1977).In fact, a predator's net energy intake for each prey …

WebApr 1, 2014 · Optimal Diet Theory suggests that individuals make foraging decisions that maximise net energy intake. Many studies provide qualitative support for this, but factors such as digestive constraints, learning, predation-risk and competition can influence foraging behaviour and lead to departures from quantitative predictions. We examined the … One classical version of the optimal foraging theory is the optimal diet model, which is also known as the prey choice model or the contingency model. In this model, the predator encounters different prey items and decides whether to eat what it has or search for a more profitable prey item. The model predicts that foragers should ignore low profitability prey items when more profitable items …
