Description
Using statistical physics methods we study the role of dynamical fluctuations in shaping the behavior of high-diversity and spatially extended heterogeneous ecosystems. After an introduction to the methods developed to study the dynamics of species-rich ecosystems, we shall focus on two main emerging phenomena: (i) chaotic dynamics due to endogenous fluctuations persisting for extremely long times, (ii) phase transitions due to demographic noise and dispersal between complete extinction and a self-sustained state with high-diversity.
