A term introduced by Philip (J. P.) Grime of the University of Sheffield, who defines it as groupings of similar or analogous genetic characteristics which recur widely among species or populations and cause them to exhibit similarities in ecology. Grime first proposed a threefold broad division of plant strategies into competitors, ruderals, and stress-tolerators. See also functional type.
