Functional redundancy in assemblages may insure ecosystem processes after perturbation potentially causing local species extinctions. Here we measure functional redundancy as the fraction of species diversity not expressed by functional diversity. We test by path analysis causal models linking diversity to community stability and conclude that functional redundancy enhanced community resilience after grazing, therefore corroborating the insurance hypothesis.
