Patch Departure Behavior of Bumble Bees: Rules and Mechanisms

Figure 1

Graphical Representations of several Bayesian patch departure rules [7, 12], for three distributions of the number of prey within patches. The ordinate represents expected remaining time in the patch. Solid circles represent encounters with prey. (a) For the Poisson distribution, prey captures yield no information and departure occurs after a fixed time independent of the number of prey encountered. (b) For the binomial distribution, each prey capture decrements expected remaining patch time. (c) For the negative binomial, each prey capture increments expected remaining patch time, but each increment in sequence is smaller.
(a) Poisson
(b) Binomial
(c) Negative binomial
