To evaluate whether critical slowing-down indicators can serve as reliable early-warning signals for approaching tipping points and collapse in complex mutualistic communities.
Simulated gradual environmental change across 79 empirical mutualistic networks leading to sequential extinction cascades and community collapse.
Computed critical slowing-down indicators from species-level and community-level biomass time series to evaluate warning signals prior to extinction events.
Critical slowing-down indicators derived from biomass time series reliably signaled the proximity to the onset of community collapse.
Specialist species served as the most sensitive indicator species for monitoring impending collapse across networks.
Trends in slowing-down metrics correlated strongly with the timing of individual species extinctions, offering a basis for ranking extinction risk.
