Optimal foraging the marginal value theorem
WebThis bachelor thesis will analyse the background of the Optimal Foraging Theory, evaluate different OFT applications and look into problems and possibilities related to them. Finally a conclusion will be made with an evaluation of the usefulness of an optimal for- aging perspective on analyses of hunter-gatherer societies on Gotland. WebNov 1, 2024 · Classic models from optimal foraging theory, specifically the marginal value theorem (MVT), are well-established tools that can generate quantitative predictions about when individuals should prefer to leave a food patch, given patch quality and the distribution of patches in the environment.
