Abstract

As a follow-up to the recent interest in simple additive models for diversity partitioning, we have used the analogy with ANOVA models to propose a consistent framework that allows both (i) apportioning the amount of regional diversity into environmentally and/or geographically-related components (ii) detecting individual species' habitat preferences using permutation tests. We addressed geographical aspects by relating diversity partition to dissimilarity measurements. An illustration based on an inventory of trees in a tropical rain forest of French Guiana is provided.
