Description:
The arrangement surrounding the central P. verrucosa colonies. Coral-coral configurations were prepared to create five arrangements: (1) controls consisting of a single colony of P. verrucosa; (2) conspecific pairings, in which a colony of P. verrucosa was adjacent to a conspecific of equal size; (3) conspecific aggregations, in which a colony of P. verrucosa was surrounded by three conspecifics of equal size; (4) heterospecific pairings, in which a colony of P. verrucosa was adjacent to a fragment of Acropora hyacinthus; and (5) heterospecific aggregations, in which a colony of P. verrucosa was surrounded by three fragments of A. hyacinthus.
