  • The pink coral pigment has been synthesized from silica (quartz sand in Thua Thien Hue province), zirconia and iron (II) sulphate hetahydrate using a mixture of sodium fluoride and potassium cloride as mineralisers to lower the temperature of reaction. By measuring colour parameters (CIE, L* a* b* ) of coloured glaze, using DTA and XRD methods we have studied the influence of mineralisers and firing temperature in pigment synthesized.

  • T he impetus to produce this book came in a brief phone call in 1998. Chuck Crumly, of Academic Press, called with an invitation and a deadline. Either The Ecology of Fishes on Coral Reefs, published in 1991, would be allowed to lapse into out-of-print status, or I would agree to produce a second edition. Looking back on all the work, I suspect it might have been wiser to say, "Let her lapse." But I didn't.

  • Widespread thermal anomalies in 1997–1998, due primarily to regional effects of the El Nin˜ o–Southern Oscillation and possibly augmented by global warming, caused severe coral bleaching worldwide. Corals in all habitats alongthe Belizean barrier reef bleached as a result of elevated sea temperatures in the summer and fall of 1998, and in fore-reef habitats of the outer barrier reef and offshore platforms they showed signs of recovery in 1999. In contrast, coral populations on reefs in the central shelf lagoon died off catastrophically.

  • For a variety of coral species, we have studied the molecular origin of their coloration to assess the contributions of host and symbiont pigments. For the corals Catalaphyllia jardineiand an orange-emitting color morph of Lobophyllia hemprichii, the pigments belong to a particular class of green fluorescent protein-like proteins that change their color from green to red upon irradiation with400 nm light.

  • It has been known for 30 years that the gorgonian coral Plexaura homomallacontains either 15S-or 15R-configur-ation prostaglandins (PGs), depending on its location in the Caribbean. Recently we showed that the 15R-PGs in the R-variety of P. homomallaare formed by a unique cyclo-oxygenase (COX) with 15Roxygenation specificity [Valm-sen, K., Ja¨rving, I., Boeglin, W.E., Varvas, K., Koljak, R., Pehk, T., Brash, A.R. & Samel, N.

  • The Pacific Islands region contains about 200 high islands and about 2 500 low islands and atolls. Apart from the Pitcairn group and the southern part of French Polynesia in the east of the area, all the islands of the area lie in the tropical zone. In general, the islands increase in size from east to west, with Papua New Guinea at the western-most edge of the region having most of the region’s land area. The islands mostly rise steeply from the deep ocean floor and have very little underwater shelf.
