The distribution of cheilostome bryozoans on the Caribbean reefs of Panama was surveyed to test the hypothesis that physically constant environments favor increased morphologic complexity, expressed as the number of zooid types within a colony. The proportion of species within defined grades of complexity did not vary significantly with locality, depth, or substratum. Some differences were found in grade-specific ecological success, measured by colony abundance and spatial cover, but these were… CONTINUE READING
