As part of the Centennial celebration of the Ecological Society of America, the ESA looks back at some of the most notable papers published in ESA journals, since Ecology first rolled out the presses in 1920. One of the 115 selected papers is a paper by Cajo ter Braak of Biometris Wageningen UR about Canoco.
All these papers will be available open-access until the end of the year.
In 1986 Cajo ter Braak published the first description of canonical correspondence analysis (CCA) in the journal Ecology and made it available to ecologists in the program Canoco, together with redundancy analysis (RDA) and other ordination methods. These methods are now also available in commercial packages and in free R software. They represent a major leap forward for community ecology, which moved in this great jump from descriptive to hypothesis-testing analyses.
