Résumé

Dormancy is a complex trait that has evolved independently many times across the tree of life. In particular many micro-organisms can enter a reversible state of vanishing metabolic activity. The corresponding dormancy periods can range from a few hours to potentially thousands of years. Also, the dormancy transitioning mechanisms are highly diverse, including spontaneous dormancy initiation and resuscitation, responsive switching due to environmental cues, and competition-induced dormancy initiation. In general, dormancy allows a population to maintain a reservoir of genotypic and phenotypic diversity (that is, a seed bank) that can contribute to its longterm survival and coexistence. In this talk, we review some of the probabilistic structures that emerge from stochastic individual based models involving dormancy.
