Description
Rock-paper-scissors, the game of childhood fame, is observed
in a diversity of natural systems ranging from competing strains of
E.coli to competing male morphs of side-blotched lizards. A
fundamental question about these natural systems is how does spatial
and temporal variation in environmental conditions (e.g. temperature,
precipitation, resource availability) influence coexistence of these
competing strategies? To address this question, I will introduce some
recent theorems about coexistence for interacting populations in
temporally or spatially heterogeneous environments and illustrate
their application to rock-paper-scissor communities.
