Towards a consensus for calculating dendrogram‐based functional diversity indices

The widely used FD index of functional diversity is based on the construction of a dendrogram. This index has been the subject of a strong debate concerning the choice of the distance and the clustering method to be used, since the method chosen may greatly affect the FD values obtained. Much of this debate has been centred around which method of dendrogram construction gives a faithful representation of species distribution in multidimensional...
