Persistence and extinction dynamics in a stochastic predator-prey model with emergent Allee effects
Carlos Granados, Leon A. Valencia
The Allee effect describes a decline in population fitness at low densities, potentially leading to extinction. In predator-prey systems, an emergent Allee effect can arise due to…
