Optimal diet theory

WebJan 18, 2024 · Optimal diet theory predicts that an animal should preferentially select for prey species based on their relative abundance and profitability (Stephens & Krebs, 1986). Landscape of fear theory predicts that a species will avoid risky habitats so long as the risks are heterogenous and perceivable (Gaynor et al., 2024 ; Laundré et al., 2010 ). 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 …
