報告摘要🧕🏿:The main purpose of this talk is to answer the question of how the white-headed langur dispersal strategies among different habitats impact the protection of this endangered species. We develop three patchy predator-prey models: First, we propose two general predator-prey dispersal models (with and without maturation delay) and obtain its threshold dynamics determined by the net reproductive number, based on which we discuss the effects of predator dispersal strategies on its persistence & extinction; Second, we consider a specific dispersal model where only the predator migrates, we construct the global stability of its coexistence equilibrium and investigate the effects of dispersal strategies on the amount of predator population.
