A Stochastic Metapopulation Model with Variability in Patch Size and Position
Analytically tractable metapopulation models usually assume that every patch is identical, which limits their application to real metapopulations. We describe a new single species model of metapopulation dynamics that allows variation in patch size and position. The state of the metapopulation is defined by the presence or absence of the species in each patch. For a system of n patches, this gi...
متن کاملA Metapopulation Model with Discrete Size Structure
We consider a discrete size-structured metapopulation model with the proportions of patches occupied by n individuals as dependent variables. Adults are territorial and stay on a certain patch. The juveniles may emigrate to enter a dispersers’ pool from which they can settle on another patch and become adults. Absence of colonization and absence of emigration lead to extinction of the metapopul...
متن کاملA spatially structured metapopulation model with patch dynamics.
Metapopulation models that incorporate both spatial and temporal structure are studied in this paper. The existence and stability of equilibria are provided, and an extinction threshold condition is derived which depends on patch dynamics (patch destruction and creation) and metapopulation dynamics (patch colonization and extinction). These results refine threshold conditions given by previous ...
متن کاملBifurcation in a Discrete Two Patch Logistic Metapopulation Model
In this paper, local bifurcation of a discrete two patch logistic metapopulation is discussed. By the central manifold method, flip bifurcation can be analyzed at the positive fixed point from the viewpoint of the dynamical system, and the system can not undergo a fold bifurcation. Simulations on this model show the discrete model can have rich dynamical behaviors. The state feedback control is...
متن کاملSPOMSIM: software for stochastic patch occupancy models of metapopulation dynamics
Classical metapopulations are groups of local populations living in networks of spatially distinct habitat patches in a balance between local extinctions and recolonizations of empty habitat. Models are needed for understanding and predicting metapopulation dynamics in changing landscapes. One particularly important question is what is the effect of habitat loss to the persistence of a metapopu...
