Abstract: We propose a new method to estimate and correct for phylogenetic inertia in comparative data analysis. The method, called phylogenetic eigenvector regression (PVR) starts by performing a principal coordinate analysis on a pairwise phylogenetic distance matrix between species. Traits under analysis are regressed on eigenvectors retained by a broken-stick model in such a way that estimated values express phylogenetic trends in data and residuals express independent evolution of each species. This partitioning is… Show more

“…Nonetheless, until recently, most studies did not account for the influence of phylogeny on the ecological similarities among assemblages (Lauder, 1981;Strauss, 1987;Emerson & Gillespie, 2008), most likely because analytical methods were used that assumed the similarity in a given characteristic was due to its independent appearance in each species (Dobson, 1985). Considerable advances in analytical techniques have enabled phylogenetic information to be incorporated into such studies, making it possible to partition the variance into at least two components: (i) the contribution of the phylogenetic history of a species, measured by phylogenetic signal (Losos, 2008); and (ii) the contribution that is unique to each species and reflects adaptation or modification in a structure (Diniz-Filho et al, 1998).Quantifying phylogenetic signal (i.e., the 'tendency for related species to resemble each other more than they resemble species drawn at random from the tree', sensu Blomberg & Garland, 2002) indicates the relationship between the degree of phylogenetic relatedness and the ecological similarity (Losos, 2008). In the context of ecomorphological analysis, the distinction between phylogenetic constraint and local adaptation may be a nonissue, because the phenotype of a species limits the type of environment in which it can survive regardless of its evolutionary conservatism (Ricklefs & Miles, 1994).…”

“…The Phylogenetic Eigenvector Regression (PVR) method (Diniz-Filho et al, 1998) was used to test the effect of phylogeny on the ecomorphological structure of the fish in the two basins. With this approach, the ecomorphological variation explained by the significant PCs is divided into two components: phylogenetic (P), which is the variation inherited from ancestors, and specific (S), which represents the independent variations of each lineage and the independent evolution of each species after speciation events; the correlation between P and S can be interpreted as phylogenetic niche conservatism (Desdevises et al, 2003;Diniz-Filho et al, 2009).The PVR method first uses a Principal Coordinate Analysis (PCoA, see Legendre & Legendre, 1998) to calculate eigenvectors from the species phylogenetic distance matrix (Diniz-Filho et al, 1998). These eigenvectors can be used as predictors in a multiple regression, in which the dependent variable is the species traits (Diniz-Filho et al, 1998).…”
