ASEXUAL REPRODUCTION IN A ZOANTHID BY FRAGMENTATION: THE ROLE OF EXOGENOUS FACTORS

摘要

Fragmentation is an important characteristic of the life history, population dynamics, and genetic structure of at least five metazoan phyla. This study represents a first report of modes of fragmentation and their relative importance to population growth in Palythoa caribaeorum(Cnidaria, Zoanthidea). Several population at two coastal sites in Brazil (Praia Portinho, on Sao Sebastiao island, and Ponta Recife, on the Sao Paulo coast)were followed for 1 yr.
