Statistical methods for biodiversity research

Ordination methods for ecologists

Statistics for ecologists A collection of useful links to sites with statistical or mathematical material relevant to ecologists.

Analyzing Ecological Data - This book is available online here.

Numerical Ecology 2nd edition - by Pierre and Louis Legendre. A classic reference text in quantitative ecology.

Numerical Ecology with R - This new book by Borcard et al. from Université de Montréal discuss both some theory on quantitative methods in ecology and how they are implemented in the R language.

Measure Biological Diversity - by Anne E. Magurran.

Tree diversity analysis - A free manual and software for common statistical methods for ecological and biodiversity studies.

Official R project homepage

R seek a great search engine for R.

Stackoverflow provides users the ability to ask and asnwer questions related to R. Questions that are well articulated are generally answered promptly. Make sure you search the archives of questions to determine whether your question was asked previously, prior to posting a new question.

R mailing lists The archives of the mailing lists provide a wealth of information about R, can be searched here.
