Figure 3. Strategy and survivorship modelling .a ,b , Proportion of simulated individual sharks surviving through model time. Those pursuing ‘lone’ foraging strategies (using only private information to locate prey patches) declined rapidly compared to ‘social’ foragers (using both private and social information), regardless of the energetic reward obtained from locating resources (a : 100 prey patches, b : 200 prey patches, for further reward ratios and patch densities see Fig S1).c ,d , Survival time of simulated sharks behaving either as wandering or central-place foragers (CPF), assuming all individuals can use both private and social information to locate prey patches. Regardless of prey abundance (c : 100 prey patches, d : 200 prey patches), the reward obtained from foraging events (Fig S2), or the starting ratio between the two foraging strategies, under all conditions only CPF individuals successfully survive for the full duration of model time. Once prey density is sufficiently high, there is no variation in likelihood of survival of CPF d .
