    Trends in growth and mortality of three coral species (Anthozoa: Scleractinia), including effects of transplantation
    Yap, H. T.; Alino, P. M.; Gomez, E. D. (Inter-Research Science Center, 1992)
    Three ecologically dominant coral species in a northern Philippine reef were compared in terms of growth and mortality and responses to transplantation. The purpose of this study was to examine the feasibility of using the species concerned in establishing new coral populations through deliberate fragmentation. The species, Acropora hyacinthus, Pocillopora damicornis and Pavona frondifera, displayed distinct differences which could be related to their respective life-history strategies. A. hyacinthus showed tendencies towards an r-mode, with rapid linear growth but also high mortality rates. Response to transplantation was poor. Pocillopora damicornis had intermediate linear growth rates and relatively high mortality. Transplants fared poorly in the initial part of the experiment though they showed successful adaptation after a year. Mortality rates of both A. hyacinthus and P. damicornis were increased by high temperatures during certain times of the year. Pavona frondifera had the highest linear growth rates and no mortality, tending towards a K-mode of life history strategy. It showed the best response to transplantation This species is thus a suitable candidate for large-scale reef restoration.

    A review of the status of Philippine reefs
    Gomez, 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.

    Reef management in developing countries: A case study in the Philippines
    Gomez, E. D. (Springer, 1997-06)
    In general the most attractive and economically valuable reefs in the world are found in developing countries. Because of these attributes, they have also become the most endangered. Due to anthropogenic threats to their productivity, there is a growing need for management. Programs for their conservation and rehabilitation are being mounted at local, regional, and international levels. Local efforts are widely distributed, showing signs of both failure and success. The situation in developing countries differs from that which prevails in developed countries for various reasons, including level of awareness, infrastructure, and law enforcement. A case history of saving a coral reef ecosystem is described in this study. It involves a recent plan to build a cement factory in the Philippines at Bolinao.
