Ecological Data Analysis cannot be ignored as a very useful source information-system/information provided by the Oklahoma State University: This is the section of the university website more known to analysts as The Ordination Web Page and fully implemented by Professor Michael W. Palmer.
Ordination is one of the most widely used methods for the individuation of relationships between ecological communities, writes Michael W. Palmer in his The Ordination Web Page. This web page was designed to answer to some of the questions most frequently asked, and more particularly aimed to students and novices. Here you can find an almost unlimited number of papers in which they are described, compared, and discussed the different techniques of sorting. The website contains the most simple concepts (and paradoxically this is also more difficult to recover) ad the more complex arguments: a section dedicated to general descriptions and references to more interesting, a section dedicated exclusively to statistical methods, a section dedicated to the softwares, and a section devoted to processing and standardization of environmental data / ecological.
