Abstract

Grinnell (1914, 1922) was the first to hypothesize an ecological basis for dispersal. He concluded that since the probability of survival for dispersers was so low, “the interests of the individual are sacrificed in the interests of the species” (Grinnell 1922, p. 379). If all dispersing individuals suffer reduced fitness, however, the trait would not evolve (MacArthur 1972). Increased individual fitness should form the basis for dispersal and habitat selection.
