1. The best of both worlds: Phylogenetic eigenvector regression and mapping
Eigenfunction analyses have been widely used to model patterns of autocorrelation in time, space and phylogeny. In a phylogenetic context, Diniz-Filho et al. (1998) proposed what they called Phylogenetic Eigenvector Regression (PVR), in which pairwise phylogenetic distances among species are submitted to a Principal Coordinate Analysis, and eigenvectors are

2. A comparison of metrics for estimating phylogenetic signal under alternative evolutionary models
Several metrics have been developed for estimating phylogenetic signal in comparative data. These may be important both in guiding future studies on correlated evolution and for inferring broad-scale evolutionary and ecological processes (e.g., phylogenetic niche conservatism). Notwithstanding, the validity of some of these metrics is under debate, especiall

3. Phylogenetic niche conservatism and biodiversity conservation of Partamona (Apidae: Meliponini) in a global climate change scenario / Conservação filogenética de nicho e conservação da biodiversidade de Partamona (Apidae: Meliponini) em um panorama de mudanças climáticas globais
A resposta de espécies a mudanças de clima depende tanto de como elas são afetadas pelas condições ambientais quanto de como respondem a longo prazo a pressões evolutivas. Neste trabalho, mostramos evidências de conservação filogenética do nicho ecológico nas espécies Partamona, um gênero de abelhas sem ferrão neotropicais, indicando há uma te

4. Phylogenetic autocorrelation and evolutionary diversity of Carnivora (Mammalia) in Conservation Units of the New World
One of the main concerns of Conservation Biology is the identification of priority areas for conservation, and the development of quantitative methods is important to achieve this task. Many phylogenetic diversity indexes and higher-taxon approaches have been used in this context. In this study, Faith's phylogenetic indexes and the number of evolutionary ind

5. Macroecologia de mamíferos neotropicais com ocorrência no Cerrado
The macroecological approach has been used recently to analyze correlations between ecological variables in large taxonomic groups, at continental scales. A positive relationship between body weight and geographic range size has been described as a poligonal space envelope form, that can be explained by ecological and evolutionary constraints. However, these

6. An examination of phylogenetic models of substitution rate variation among lineages
Molecular evolutionary rates can show significant variation among lineages, complicating the task of estimating substitution rates and divergence times using phylogenetic methods. Accordingly, relaxed molecular clock models have been developed to accommodate such rate heterogeneity, but these often make the assumption of rate autocorrelation among lineages.
