Nonlinear relationships and phylogenetically independent contrasts.

Journal of evolutionary biology - 1 May 2004

Quader S, Isvaran K, Hale R E, Miner B G, Seavy N E

Abstract excerpt

The method of phylogenetically independent contrasts is commonly used for exploring cross-taxon relationships between traits. Here we show that this phylogenetic comparative method (PCM) can fail to detect correlated evolution when the underlying relationship between traits is nonlinear. Simulations indicate that statistical power can be dramatically reduced when independent contrasts analysis is used on...
