Description
Population dynamics has traditionally focused on the study of what occurs in ecological regimes that only change their relationships quantitatively. However, populations that transition from one ecological regime to another, such as predation or parasitism shifting to mutualism, or vice versa, have been extensively documented in diverse ecological contexts. When population dynamics has addressed those transitions, it usually follows ad hoc mechanisms or uses different dynamics for each regime. Here, we present a model that combines adaptive dynamics with a generalized population dynamics model \cite{stucchi2020general} in an integrated way, which allows the transition between ecological regimes. We use a microbial toy-model that despite its simplicity shows that such transitions might occur naturally \cite{stucchi2022prevalence} for different set of parameters and serves as a proof of concept. We also show a few simulations that resemble empirical cases of ecological transitions driven by evolution.
