A system-centered probabilistic formalism linking multiple equilibria and biodiversity in ecological and evolutionary models
Hiba Nassor, Hermine Biermé, Elisabeth Herniou +1
Ecological and evolutionary communities do not always settle into a single predictable configuration. Models such as Lotka-Volterra or replicator dynamics may predict several admis…

Backward bifurcations in spatial replicator models:when invasion criteria fail to predict coexistence
Tomas Freire, Erida Gjini, Sten Madec
The replicator equation is a central framework for studying frequency--dependent selection in ecology and evolutionary game theory. In well-mixed populations, the long-term outcome…

Multi-strain SIS dynamics with coinfection under host population structure
Sten Madec, Nicola Cinardi, Erida Gjini
Coinfection phenomena are common in nature, yet there is a lack of analytical approaches for coinfection systems with a high number of circulating and interacting strains. In this…
