Abstract:
According to the Rate Maximization Model the finder's advantage is an environmental factor modulating social foraging strategies. One factor that can influence the finder's advantage is the patches' setup. We analyzed the strategies of Wistar rats foraging in groups n = 4 in a 4 × 3 array of deposits where only four of them were baited (patches) with different configurations on each trial. Specifically, the goal was to assess whether the finder's advantage varied according to the distribution (Square vs. Zig-zag) and distance (Small vs. Large) between patches. Foraging responses were classified as production (seeking for food) or scrounging (tracking conspecifics) to calculate the frequency of use of each strategy in each group and estimate the induced finder's advantage in each situation. In patch-setups with short distances, production was more common and the finder's advantage higher. Results can be explained by the combined effect of a local enhancing and simultaneous patch exploitation on small setups.
