摘要

Ricciardi (Biol Invas 28(1):12, 2026) argues that globally increasing invasion rates threaten ecosystem sustainability by elevating the probability of disruptive impacts. Here, I contend that equating invasion rates with sustainability risk oversimplifies invasion dynamics by conflating introduction with impact and underrepresenting probabilistic filters, interaction structures, context dependence, and non-additive effects. Instead, I argue that sustainability assessments require empirical links to realized functional and structural ecosystem change rather than reliance on invasion rates as a dominant proxy for risk.
