ABSTRACT

Canonical correspondence analysis (CCA) was introduced in ecology by ter Braak (1986) as a new multivariate method to relate species communities to known variation in the environment. Since then, four CCA papers (ter Braak, 1986, 1987, 1988c; ter Braak and Verdonschot, 1995) have been cited more than 3,000 times in the Web of Science, approximately 10% of which were in 2010 and 6% (= 180) outside ecology. Independently, CCA was invented by JeanDominique Lebreton and Daniel Chessel (Chessel et al., 1987; Lebreton et al., 1988a, 1988b).
