Introduced species, as a biological process, refers to the human-mediated translocation and establishment of organisms outside their native geographic ranges, thereby altering biotic community composition and ecosystem dynamics. This process involves transport (intentional or accidental), release or escape, survival, and reproduction in the recipient environment, often bypassing natural dispersal barriers. Once established, introduced species may undergo rapid ecological and evolutionary responses, including niche shifts, adaptation to novel conditions, and altered interaction networks (e.g., predation, competition, mutualism). The process of species introduction can drive changes in community structure, energy flow, and biogeochemical cycles, and in some cases leads to biological invasions with significant impacts on native biodiversity and ecosystem functioning.
A new framework designed to guide one of the hardest decisions in conservation—whether to move a species outside its historical range to save it from extinction—has been published in Conservation Science and Practice, capping ...
