Environmental variation, individual information and group performance
Friday seminar by Matina Donaldson-Matasci
Many organisms have evolved to collect information about a changing, uncertain environment. What happens when different individuals receive different information about the same environment? Does this affect the strategies they use for processing, using and perhaps sharing that information? What are the impacts on fitness? I will approach these questions from three different perspectives: (1) an information-theoretic model of bet-hedging and developmental plasticity in an uncertain environment; (2) a combination of lab experiments and mathematical models of soldier deployment in colonies of turtle ants; and (3) field experiments with pollen-foraging honey bees. In these three contexts, I will explore the relationship between environmental variation, information and fitness and how this may shape the evolution of information flow in individuals, social groups, and populations.
