Query: Very lucid discussion

I have a used version of this book (ca 1988). I originally became aware of this title while a graduate student working on an MS back in the mid '90's. I needed to do some statistical evaluation of some data and I could never get a very clear explanation of the methodolgy and treatment of some multivariate analyses that were recommended to me. Statistical Ecology provided very lucid discussions of the concept and applications of several uni- and multivariate methods. I especially liked the chapter on non-linear ordinations and their use. The presentation on detrended correspondence analysis is excellent (and the method that I ended up utilizing to summarize and interpret my data). It is an excellent reference that will greatly enhance your research design and data interpretation.
