Uptake and partitioning of copper and cadmium in the coral Pocillopora damicornis.
Coral-reef ecosystems are increasingly being impacted by a wide variety of anthropogenic inputs, including heavy metals, which could be contributing to coral reef stress and bleaching episodes. Fragments of Pocillopora damicornis were exposed in the laboratory to cadmium (Cd) or copper (Cu) chlorides (0, 5, 50 microg l(-1)) for 14 days and analyzed for metal content in the whole association, al...
متن کاملInhibition of photosynthetic CO₂ fixation in the coral Pocillopora damicornis and its relationship to thermal bleaching.
Two inhibitors of the Calvin-Benson cycle [glycolaldehyde (GA) and potassium cyanide (KCN)] were used in cultured Symbiodinium cells and in nubbins of the coral Pocillopora damicornis to test the hypothesis that inhibition of the Calvin-Benson cycle triggers coral bleaching. Inhibitor concentration range-finding trials aimed to determine the appropriate concentration to generate inhibition of t...
متن کاملMixed asexual and sexual reproduction in the Indo-Pacific reef coral Pocillopora damicornis
Pocillopora damicornis is one of the best studied reef-building corals, yet it's somewhat unique reproductive strategy remains poorly understood. Genetic studies indicate that P. damicornis larvae are produced almost exclusively parthenogenetically, and yet population genetic surveys suggest frequent sexual reproduction. Using microsatellite data from over 580 larvae from 13 colonies, we demons...
متن کاملElevated Temperature Alters the Lunar Timing of Planulation in the Brooding Coral Pocillopora damicornis
Reproductive timing in corals is associated with environmental variables including temperature, lunar periodicity, and seasonality. Although it is clear that these variables are interrelated, it remains unknown if one variable in particular acts as the proximate signaler for gamete and or larval release. Furthermore, in an era of global warming, the degree to which increases in ocean temperatur...
متن کاملIntensive fish farming in the Philippines is detrimental to the reef-building coral Pocillopora damicornis
To determine the effects of fish farm effluent on the reef-building species Pocillopora damicornis, we exposed different life stages of the coral to a gradient of effluent concentrations. After 81 d no juvenile coral survived at the Fish Farm site or at the site receiving intermediate concentrations, and survival rates were low (<20%) at the site receiving minimal effluent concentrations and at...
