Spatial Variation in Background Mortality among Dominant Coral Taxa on Australia's Great Barrier Reef
Even in the absence of major disturbances (e.g., cyclones, bleaching), corals are consistently subject to high levels of background mortality, which undermines individual fitness and resilience of coral colonies. Partial mortality may impact coral response to climate change by reducing colony ability to recover between major acute stressors. This study quantified proportion of injured versus un...
متن کاملContrasting Lesion Dynamics of White Syndrome among the scleractinian corals Porites spp
White syndrome (WS) is currently the most prevalent disease of scleractinian corals in the Indo-Pacific region, with an ability to exist in both epizootic and enzootic states. Here, we present results of an examination of WS lesion dynamics and show that potentially associated traits of host morphology (i.e., branching vs. massive), lesion size, and tissue deposition rate influence disease seve...
متن کاملDistribution and Abundance of the Corals around Hengam and Farurgan Islands, the Persian Gulf
The percentage cover and distribution of scleractinian corals were studied at two Iranian islands in the Persian Gulf. Survey techniques involved the use of 20-m line transects placed at 4-9 m depth interval, parallel to the shore. GIS based maps were employed to show the distribution of hard corals. In Farurgan Island, hard coral cover was concentrated in the west and north-west of the island,...

the concentration contents of ca, mg, sr and zn in porites corals from pulau langkawi, pulau redang and pulau tioman were presented. the corals were cleaned and the growth rate examined visually. the growth rate of porites in malaysia waters was between 5 to 25 mm yr-1 and each band was selected for determining the metal contents using the atomic absorption spectrophotometer (aas). the mean val...
متن کاملWater ̄ow and prey capture by three scleractinian corals, Madracis mirabilis, Montastrea cavernosa and Porites porites, in a ®eld enclosure
Scleractinian corals experience a wide range of ̄ow regimes which, coupled with colony morphology, can aect the ability of corals to capture zooplankton and other particulate materials. We used a ®eld enclosure oriented parallel to prevailing oscillatory ̄ow on the forereef at Discovery Bay, Jamaica, to investigate rates of zooplankton capture by corals of varying morphology and polyp size unde...
