Supplement 1. Data set for the bird communities.

<h2>File List</h2><blockquote> <p><a href="birds.txt">birds.txt</a> -- data set for the analysis of bird communities </p> <p> </p> </blockquote><h2>Description</h2><blockquote> <p>The data set consists of a data frame, with species as rows and sample sites as columns. Labels for the sites are codes : the first three letters indicate the local region ['Alg' (Algeria), 'Bur' (Burgundy), 'Cor' (Corsica), 'Pol' (Poland) and 'Pro' (Provence)] and numbers indicate the vegetation stage (from 1 bushy to 6 forested). From this data set, one can obtain the results given in the article by following the instructions provided in <a href="appendix-A.htm">Appendix A</a>. This data set comes from the combination of two studies whose references are given below :<br> Blondel, J., and H. Farré. 1988. The convergent trajectories of bird communities along ecological successions in European forests. Œcologia (Berlin) <b>75</b>:83–93.<br> Abouheif, E. 1999. A method for testing the assumption of phylogenetic independence in comparative data. Evolutionary Ecology Research <b>1</b>:895–909. </p> </blockquote>
