- A review of the status of Philippine reefsGomez, E. D.; Aliño, P. M.; Yap, H. T.; Licuanan, W. Y. (Elsevier BV, 1994-01)Since 1979, the status of Philippine reefs has been periodically updated. While conditions of the reefs during the early surveys were assessed in terms of live coral cover per se, the ‘coral mortality index’ was applied to the sets of data collected during the past 7 yr which may be a better gauge in determining the health of the reefs. Generally, most reefs surveyed are in fair condition. Major destructive factors described are sedimentation and siltation from coastal development and activities inland, illegal and destructive methods of fishing, and overfishing. If the reefs are to continue to provide for the present and future users, the ecological processes that render them productive must be maintained through integrated approaches of coastal area management.
- Effects of the soft coral Xenia puertogalerae on the recruitment of scleractinian coralsAtrigenio, M. P.; Aliño, P. M. (Elsevier, 1996-10)The effects of Xenia puertogalerae on the recruitment of juvenile corals was studied at two levels, involving early and more advanced settlement stages. Inhibition by X. puertogalerae was evident. Terracotta tiles established near soft coral colonies had fewer recruits than those located away from the soft corals. This inhibitory effect may be selective as acroporids were able to settle and survive in the presence of Xenia. This selectivity in allowing recruitment implies an important role for X. puertogalerae in determining succession and community structure. It may affect community structure by favouring the establishment of tolerant species, but effectively deters settlement of other corals in the area.
