Geographic variation in densities of herbivorous fishes and sea urchins inside territories of Stegastes nigricans. (a) frequencies in which Stegastes nigricans chased invading fishes out of their territories per 10 minutes, (b) the densities of sea urchins found inside the territories of S. nigricans in the three localities of Kenya, the Maldives, and Okinawa. Numbers in parentheses indicate the number of individual damselfish we observed. Different letters indicate significant differences at the 5% level by the Games-Howell test. *Observation data in Okinawa are cited from [28].
