摘要: We study a variant of Hanski's incidence function model that accounts for the evolution over time landscape characteristics which affect persistence local populations. In particular, we allow probability extinction to evolve according Markov chain. This covers widely studied case where patches are classified as being either suitable or unsuitable occupancy. Threshold conditions population obtained using an approximating deterministic is realized in limit number becomes large.
