摘要

Aggregations of fungiid corals are common on Indo-Pacific reefs, but visible signs of direct competition are uncommon. Although negative interactions between fungiids are generally thought to be negligible, the results of an experiment manipulating aggregation and species identity indicated that per capita calcification rates of Fungia concinna were depressed when surrounded by five other Fungia. The reduction in growth did not vary if neighbors were Fungia concinna or Fungia paumotensis, suggesting that these two related species overlap substantially in their competitive impacts. However, mucus production and movement occurred more frequently in heterospecific than conspecific groups. These results suggest that there is a cost to group living, but depressed growth must be weighed against the potential benefits of successful spawning in conspecific aggregations.
