TLDR
A decomposition of functional β-diversity, i.e. the dissimilarity in functional composition between communities, is developed into a functional turnover and a functional nestedness-resultant component.Abstract:
Aim
One of the main gaps in the assessment of biodiversity is the lack of a unified framework for measuring its taxonomic and functional facets and for unveiling the underlying patterns.
Location
Europe, 25 large river basins.
Methods
Here, we develop a decomposition of functional β-diversity, i.e. the dissimilarity in functional composition between communities, into a functional turnover and a functional nestedness-resultant component.
Results
We found that functional β-diversity was lower than taxonomic β-diversity. This difference was driven by a lower functional turnover compared with taxonomic turnover while the nestedness-resultant component was similar for taxonomic and functional β-diversity.
Main conclusions
Fish faunas with different species tend to share the same functional attributes. The framework presented in this paper will help to analyse biogeographical patterns as well as to measure the impact of human activities on the functional facets of biodiversity.read more

Interpreting the replacement and richness difference components of beta diversity
TL;DR: This paper first reviews the historical development of the formulae for decomposing dissimilarities into replacement, richness difference and nestedness indices, and shows that local contributions of replacement and richness difference to total beta diversity can be computed and mapped.

How many dimensions are needed to accurately assess functional diversity? A pragmatic approach for assessing the quality of functional spaces
TL;DR: It is shown that using a poor-quality functional space could led to a biased assessment of functional diversity and false ecological conclusions, so this work advises a pragmatic approach consisting of computing all the possible functional spaces and selecting the most parsimonious one.

Traits Without Borders: Integrating Functional Diversity Across Scales

TL;DR: This novel approach could revolutionize FD-based research by allowing quantification of the various FD components from organismal to macroecological scales, and allowing seamless transitions between scales.

Separating the two components of abundance-based dissimilarity: balanced changes in abundance vs. abundance gradients
TL;DR: The novel partition separating two components of abundance-based dissimilarity may be useful to assess biodiversity patterns and to explore their causes, as substitution and loss of individuals are patterns that can derive from completely different processes.

Functional ecology of fish: current approaches and future challenges
TL;DR: This work presents the functional traits that have already been used to assess the key functions played by fish and highlights how a trait-based framework could provide valuable insights on the mechanistic links between global changes, functional diversity of fish assemblages, and ecosystem services.

Rebuilding community ecology from functional traits.
TL;DR: It is asserted that community ecology should return to an emphasis on four themes that are tied together by a two-step process: how the fundamental niche is governed by functional traits within the context of abiotic environmental gradients; and how the interaction between traits and fundamental niches maps onto the realized niche in the context a biotic interaction milieu.

A distance-based framework for measuring functional diversity from multiple traits
TL;DR: A highly flexible distance-based framework to measure different facets of FD in multidimensional trait space from any distance or dissimilarity measure, any number of traits, and from different trait types (i.e., quantitative, semi-quantitative, and qualitative).

Partitioning the turnover and nestedness components of beta diversity
TL;DR: In this paper, a unified framework for the assessment of beta diversity, disentangling the contribution of spatial turnover and nestedness to beta-diversity patterns, is provided, which is crucial for our understanding of central biogeographic, ecological and conservation issues.
