Connecting the Parameters of Local Extinction and Metapopulation dynamics

摘要: This paper explores the correspondence between parameters of an extinction model analysed by Lande, Foley and Middleton et al. incidence function metapopulation dynamics. The model, intrinsic rate population increase (r), its variance (v) ceiling (K), can be mapped to describing scaling probability local (E) with patch area (A), E = eA X, via equations s x r eDs/s, where 2r/v, D is density K= DA. I explore this two empirical examples, a mainlandisland European common shrew (Sorex araneus) on islands in lakes classical American pika (Ochotona princess. most robust result which value decreases increasing strength environmental stochasticity. Thus impact stochasticity dynamics can, principle, inferred from pattern habitat occupancy metapopulation.
