Who's invading what? Systems thinking about invasive species

摘要: While invasive plant species have dramatic and varied effects, this paper examines the focus of symposium on their “threat to native biodiversity ecosystems”. This claim implies that there is (i) an enduring something, (ii) it native, (iii) under threat from species. I examine these implications in turn, first considering role observer invasion biology, particularly preferring a nature characterized by stability rather than flux. Second, concept “native” given humans are thoroughly embedded within natural ecological systems. Third, demonstrate how our exclusion conditions us consider primary one among many interacting causal agents global change; particular, recent evidence indicates agents, which include human-caused disturbances warming (not mention human population growth trade), may overwhelm effects per se. For the...
