A new phylogenetic comparative method is proposed, based on mapping two continuous characters on a tree to generate data pairs for regression or correlation analysis, which resolves problems ofmultiple character reconstructions, ...

Aim: There is little consensus on which environmental variables are best at predicting multiple dimensions of diversity. We ask whether there are common environmental correlates of diversity, despite ecological differences, ...

Summary: PCCA (phylogenetic canonical correlation analysis) is a new program for canonical correlation analysis of multivariate, continuously valued data from biological species. Canonical correlation analysis is a technique ...

Bird species exhibit great diversity in digestive tract morphology and enzymatic activity that is partly correlated with the chemical composition of their natural diets. However, no studies have assessed whether the ...

A new phylogenetic comparative method called DUALCOR is presented to evaluate the evolutionary response of a character to non-evolving external factors, such as environmental variables. The method treats the character as ...

Vocalization is one of the major means of communication in animal groups and is crucial in anuran mate recognition. Animal calls consist of spectral and temporal parameters, whose evolution can be influenced by environmental ...

The high diversity of plant species in the tropics has revealed complex phenological patterns and reproductive strategies occurring throughout the year. Describing and analysing tropical plant phenology, and detecting ...
