A Unifying Framework for Metapopulation Dynamics

摘要: Abstract: Many biologically important processes, such as genetic differentiation, the spread of disease, and population stability, are affected by (natural or enforced) subdivision populations into networks smaller, partly isolated, subunits. Such “metapopulations” can have extremely complex dynamics. We present a new general model that uses only two functions to capture, at metapopulation scale, main behavior metapopulations. show how complex, structured models be translated our generalized framework. The dynamics arising from some biological processes illustrated: rescue effect, Allee what we term “antirescue effect.” antirescue effect captures instances where high migration rates deleterious persistence, phenomenon has been largely ignored in conservation theory. Management regimes ignore significant will inadequate may actually...
