WebMar 24, 2009 · Arguably one of the most influential contributions to optimal foraging theory was the marginal value theorem (MVT) ( 10, 13, 14 ). MVT uses an optimality framework to predict how organisms should allocate foraging effort to patches of differing quality before leaving, and by extension, predicts broad scale patterns of movement across a landscape. iphone 7 disabled
