A Distance-based Framework for Measuring Functional Diversity from Multiple Traits

Laliberte, E. and P. Legendre

Publication Date:

A new framework for measuring functional diversity (FD) from multiple traits has recently been proposed. This framework was mostly limited to quantitative traits without missing values and to situations in which there are more species than traits, although the authors had suggested a way to extend their framework to other trait types. The main purpose of this note is to further develop this suggestion. We describe 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). This new approach allows for missing trait values and the weighting of individual traits.
