摘要: The existing system of nature reserves in Australia is inadequate for the long-term conservation and restoration native biological diversity because it fails to accommodate, among other elements, large scale ecological processes change, including physical biotic transport landscape. This paper an overview connectivity elements that inform a scientific framework significantly improving prospects Australia's biodiversity. forms basis WildCountry programme. programme has identified at landscape, regional continental scales as critical component effective system. Seven categories phenomena are reviewed require landscape permeability must be considered when planning maintenance resilience Australia: (1) trophic relations scales; (2) animal migration, dispersal, movements individuals propagules; (3) fire disturbance (4) climate variability space time human forced rapid change; (5) hydroecological flows all (6) coastal zone fluxes organisms, matter, energy; and, (7) spatially-dependent evolutionary scales. Finally, we mention eight cross-cutting themes further illuminate interactions implications seven connectivity-related assessment, planning, research, management, suggest how results might applied by analysts, planners, scientists, community conservationists.
