“De-extinction” in conservation: Assessing risks of releasing “resurrected” species

摘要: Abstract Biodiversity is decreasing at an alarming rate, and it therefore important to set ambitious targets explore innovative tools, such as de-extinction, protect recover species. However, also essential that risks associated with release of proxies for extinct species into the wild, be carefully evaluated. Risks releases parallel those introducing non-native or re-introducing locally include possibility proxy becomes invasive affects native species, communities, ecosystems through predation, competition, browsing, hybridisation, facilitation spread diseases, various ecosystem-level impacts changed hydrology fire regimes. It releasing a subjected rigorous application advances in risk assessment science. substantial limits methods must recognized, safety existing maintenance ecosystem functions should privileged over potential benefits when reliability these assessments limited, especially likely proxied long extinct. Quantifying costs indirect effects – lessened public concern biodiversity loss increased interest conservation based on “resurrected” charismatic do not appear tractable current methods.
