Invasives: Classify with Care

摘要

A STATEMENT MADE BY DAVIS AND COAUTHORS (7) last month urged "conservationists and land managers to organize priorities around whether species are producing benefits or harm to biodiversity, human health, ecological services and economies." In the ensuing tumult, their ideas have become obfuscated by semantics. In the Letter "Invasives: A major conservation threat" (22 July, p. 404), M. Lambertini et al. accuse Davis et al. of "proposing] downsizing the struggle against invasives." This description is misleading.
