We develop a theoretical framework to study the interplay of these ...

However, a precise definition of functional diversity, and hence a framework for its quantification, have proved elusive. We present a definition based on the analogy of the components of species diversity / richness, evenness and divergence. These concepts are appl...

متن کاملA test of the cross-scale resilience model: Functional richness in Mediterranean-climate ecosystems
Ecological resilience has been proposed to be generated, in part, in the discontinuous structure of complex systems. Environmental discontinuities are reflected in discontinuous, aggregated animal body mass distributions. Diversity of functional groups within body mass aggregations (scales) and redundancy of functional groups across body mass aggregations (scales) has been proposed to increase ...
