Varying effects of connectivity and dispersal on interacting species dynamics

摘要: Abstract Increased landscape fragmentation can have deleterious effects on terrestrial biodiversity. The use of protected areas, as islands conservation, has limits to the extent biodiversity conservation due isolation and scale. As a result, there is push transition from solely developing areas policies that also support corridor management. Given complexities multi-species interaction fragmented landscape, managers need additional tools aid in decision-making policy development. We develop an agent-based model (ABM) two-patch metapopulation with local predator–prey dynamics variable, density-dependent species dispersal. goal assess how connectivity between patches, given variety dispersal schema for targeted interacting populations, promotes coexistence among predators prey. experiment conducted suggests levels at both extremes, representing very little risk high mortality, do not augment likelihood while intermediate do. Furthermore, probability increases spans wide range when movement less probabilistic more dependent population feedback. Knowledge these tradeoffs essential assessing value habitat corridors, be further elucidated under framework.
