Diurnal Occupancy of Crevices and Overhangs by Fishes on the Caicos Bank, Turks and Caicos Islands, British West Indies
The presence of 60 fish species was recorded during daytime visual censuses of 20 large crevices and overhangs over four seasons (711 observations) on the Caicos Bank, Turks and Caicos Islands, British West Indies. Data for 26 species were analyzed, We tested five hypotheses: (1) the number of species occupying sites during the day changes with season, (2) the presence of some species changes with season, (3) associations exist between fish species and site features, (4) interspecific associations among fishes exist, and (5) physical features of the sites affect numbers of species. Tests of all five hypotheses indicated significance at P < 0.05.
