文摘In this paper,five different models for five different kinds of diseases occurring in wildlife populations are introduced.In all models,a logistic growth term is taken into account and the disease is transmitted to the susceptible population indirectly through an envi-ronment reservoir.The time evolution of these diseases is described together with its spatial propagation.The character of spatial homogeneous equilibria against the uniform and non-uniform perturbations together with the occurrence of Hopf bifurcations are discussed through a linear stability analysis.No Turing instability is observed.The partial differential field equations are also integrated numerically to validate the stability results herein obtained and to extract additional information on the temporal and spatial behavior of the different diseases.
