SIMPLE FORAGING FOR SIMPLE FORAGERS (joint work with Bezalel Peleg, Mor Amita and Avi Shmida)

Abstract: We try to explain how solitary bees (as examples of simple foragers), without any communication, will distribute themselves in a field of flowers according to something known as the Ideal Free Distribution, while any individual exhibits the so-called Matching Law when alone. We discuss two types of simple foraging strategies. Each of these strategies explains the appearance of the Ideal Free Distribution in a multi-bee community as well as as the Matching Law in an experimental set-up. This means that a population of bees will distribute itself over the nectar sources according to available supplies, while a single individual will match the available supplies by its number of visits to the different sources. Moreover, these strategies also explain why in certain situations bees may behave as if they are risk-averse, while in others as risk-prone.
