Finite population effects on optimal communication for social foragers
We find that foraging efficiency tapers off when recruitment probability is too high -- a phenomenon that does not occur in the infinite-population model, even though it occurs for any finite population size.
Evolutionary Dynamics Within and Among Competing Groups
We apply this theory to analyze how mechanisms known to promote cooperation within a single group -- including assortment, reciprocity, and population structure -- alter evolutionary outcomes in the presence of competition among groups.
Optimality of intercellular signaling: direct transport versus diffusion
There is a critical number of signaling molecules at which the efficiency of the two mechanisms are the same.
Selfish optimization and collective learning in populations
When success is measured as payoff in a game played against another learner, mutual selfishness typically fails to produce the optimal outcome for a pair of individuals.
Long-Time Behavior of a PDE Replicator Equation for Multilevel Selection in Group-Structured Populations
In many biological systems, natural selection acts simultaneously on multiple levels of organization.
