Coral surface temperature was investigated with multiple temperature sensors mounted on hemispherical and branching corals under (a) artificial lighting and controlled flow; (b) natural sunlight and controlled flow; and (c) in situ conditions in a shallow lagoon, under naturally fluctuating irradiance, water flow, and temperature. Under high irradiance and low flow conditions, hemispherical cor...

This work analyzes the mortality, recovery, and shifts in the composition of scleractinian corals from Puerto Rico one decade after the 2005 regional coral bleaching event. Temporal and spatial patterns of coral community structure were examined using a stratified, non-random sampling approach based on five permanent transects per reef at 16 reef stations. A negative correlation between percent...

Conservation priorities are calculated on the basis of species richness, endemism, and threats. However, areas ranked highly for these factors may not represent regions of maximal evolutionary potential. The relationship between geography and evolutionary innovation was analyzed in a dominant complex of Caribbean reef corals, in which morphological and genetic data concur on species differences...

Nitrogen fixation, as measured by acetylene reduct~on, has been detected to be associated with various hermatypic corals. Experiments were carried out on the massive coral Favia f a v u s both in situ and in the laboratory. Nitrogen fixation activity was found to be light dependent and fully inhibited by 5 X 10-6 M DCMU [3-(3,4-dichloropheny1)-1,l-dimethylurea Addition of glucose restored nitro...

Moira Decima and Holly Kindsvater Abstract Settlement patterns of two Dascyllus species provide insight into the relationship between recruits and adult distribution of reef fish larvae because of the close association between damselfish and settlement substrate. In Moorea, experimental coral heads were monitored for sixteen days for gregarious settlement by D. flavicaudus and D. aruanus. Three...

Feeding preferences of the crown-of-thorns sea star, Acanthaster planci (L.), were studied in a series of laboratory-based feeding trials wherein sea stars were provided with equal availability of six different coral species. The order in which corals were consumed was then used to ascertain feeding preferences. Crown-of-thorns sea stars exhibited strong and consistent feeding preferences acros...

z Higher than normal sea surface temperatures cause increased stress to corals and result in coral bleaching, and frequently in mortality. We have a better understanding of why the apparently stable symbiosis between corals and their symbiotic dinoflagellate (zooxanthellae) algae breaks down. Bleaching results in the loss of the algae and a reduction in the coral’s energy producing systems; sev...

Direct measurement of U and Th by mass spectrometry recently provided a spectacular improvement in the precision of coral dating by the U-Th disequilibrium method [1]. Mass spectrometric data also provide a much better resolution for the examination of subtle diagenetic effects revealed by small variations of the 234U//238U ratio. Such perturbations may strongly affect the accuracy of the U-Th ...

anthozoan species, including reef-building corals (Kawaguti, 1954; Porter, 1974; Lasker, 1979), gorgonians (Wainwright, 1967) and sea anemones (Pearse, 1974; Sebens and Deriemer, 1977). Most reef corals expand their tentacles only at night (Lewis and Price, 1975; Porter, 1974). A few species expand their tentacles during daytime and several species have continuously expanded tentacles (Eguchi, ...
