The book describes and discusses the numerical methods which are successfully being used for analysing ecological
data, using a clear and comprehensive approach. These methods are derived from the fields of mathematical physics,
parametric and nonparametric statistics, information theory, numerical taxonomy, archaeology, psychometry, sociometry,
econometry and others. Compared to the first edition of Numerical Ecology, this second edition includes three new
chapters, dealing with the analysis of semiquantitative data, canonical analysis and spatial analysis. New sections
have been added to almost all other chapters. There are sections listing available computer programs and packages
at the end of several chapters. As in the previous English and French editions, there are numerous examples from
the ecological literature, and the choice of methods is facilitated by several synoptic tables.
