Phylogenies in Ecology

Marc W. Cadotte is associate professor of biology at the University of Toronto, Scarborough. T. Jonathan Davies is assistant professor of biology at McGill University.

"Ecophylogenetics overlays knowledge of the origin of species with contemporary patterns found in the study of biological communities. To enhance understanding of this new synthesis, the authors provide not only data, but also the programming code (in the R language) so readers can test their comprehension... With 101 figures, 285 snippets of R language programming code, and a 43-entry glossary, this book is as much a how to guide as it is an introduction to this new approach."--Choice
