Journal ArticleDOI
New multidimensional functional diversity indices for a multifaceted framework in functional ecology.
TL;DR: This study suggests that decomposition of functional diversity into its three primary components provides a meaningful framework for its quantification and for the classification of existing functional diversity indices.
Journal ArticleDOI
A functional approach reveals community responses to disturbances
David Mouillot,David Mouillot,Nicholas A. J. Graham,Sébastien Villéger,Sébastien Villéger,Norman W. H. Mason,David R. Bellwood +6 more
TL;DR: Empirical evidence is synthesized and a theoretical framework, based on species positions in a functional space, as a tool to reveal the complex nature of change in disturbed ecosystems is presented.
Journal ArticleDOI
Functional diversity measures: an overview of their redundancy and their ability to discriminate community assembly rules
TL;DR: It is demonstrated that functional diversity indices have the potential to reveal the processes that structure biological communities and to accurately assess functional diversity and establish its relationships with ecosystem functioning and environmental constraints.
Journal ArticleDOI
Defining and measuring ecological specialization
Vincent Devictor,Vincent Devictor,Joanne Clavel,Romain Julliard,Sébastien Lavergne,David Mouillot,Wilfried Thuiller,Patrick Venail,Sébastien Villéger,Nicolas Mouquet +9 more
TL;DR: This study clarifies ecological specialization by reviewing the strengths and limitations of different approaches commonly used to define and measure ecological specialization, and illustrates how this review can be used as a practical toolbox to classify widely used metrics of ecological specialization in applied ecology.
Journal ArticleDOI
Contrasting changes in taxonomic vs. functional diversity of tropical fish communities after habitat degradation.
TL;DR: Changes in taxonomic diversity, in functional diversity, and in functional specialization of estuarine fish communities facing drastic environmental and habitat alterations are studied in the Terminos Lagoon of primary concern for its biodiversity, its habitats, and its resource supply.
