Growth and ergodicity breaking in ecosystems and social systems — •Jan Nagler — Frankfurt School

As highlighted in a recent perspective article [Science 359: 738, 2018], in ecology exact predictions are extremely challenging. In the presentation, we ask how do species evolve in environments with asymmetric fluctuating temperature profiles. We study how natural selection do not lead to adaption to the mean temperature but to a value that is shifted and given by the skewness of the temperature profile (and also by the fitness function of the species). This prediction is derived from first principles and first results are presented in nematodes (in vitro). More generally, we discuss effects from ergodicity breaking for evolutionary game theory [PRL 120: 058101, 2018], coupled ecosystems and for climate change.
