Abstract: | We describe existing models of the relationship between species diversity and ecological function, and propose a conceptual
model that relates species richness, ecological resilience, and scale. We suggest that species interact with scale-dependent
sets of ecological structures and processes that determine functional opportunities. We propose that ecological resilience
is generated by diverse, but overlapping, function within a scale and by apparently redundant species that operate at different
scales, thereby reinforcing function across scales. The distribution of functional diversity within and across scales enables
regeneration and renewal to occur following ecological disruption over a wide range of scales.
