Sea Urchin Mass-Mortality: Effects on Reef Algal Abundance, Species Composition, and Metabolism and Other Coral Reef Herbivores
Grazing by Diadema anti l larum has been demonstrated to c o n t r o l the biomass, s p e c i e s composit ion, and most r e c e n t l y , the metabol ism of many coral r e e f algal turf communit ies. The m a j o r i t y of these data have been obta ined us ing i n c l u s i o n e x c l u s i o n cage exper iments. The r e c e n t mass-mortal i ty of t h i s sea urchin in the Car ibbean prov i...
متن کاملAntibacterial activity of ovary extract from sea urchin Diadema setosum.
OBJECTIVE Sea urchin gonad is considered as a highly prized delicacy in several countries. It is also rich in valuable bioactive compounds including polyunsaturated fatty acids (PUFAs) and β-carotene. This study was undertaken to examine the antimicrobial properties of the ovary extract from sea urchin Diadema setosum against selected Gram-negative and Gram-positive bacteria. MATERIALS AND ME...
متن کاملHT248 Physiology and behaviour of the long-spined sea urchin, a keystone Caribbean coral reef herbivore
It was only after an unidentified pathogen caused a mass mortality event, killing an estimated 98% of all individuals, that the true ecological importance of the sea urchin Diadema antillarum was understood. This mass mortality affected the entire Caribbean, all but wiping out this species on coral reefs throughout the region. Unfortunately D. antillarum are important herbivores on Caribbean re...
متن کاملSpatial and temporal distribution of larvae of coral reef fishes in northern Red Sea, Egypt
The larval community of coral reef fishes in the Red Sea was studied in coastal and offshore sites to determine the effects of the exposure to waves and currents and the distance from the shore in structuring the larval fish community. Plankton sampling from inshore and offshore sites and the exposed and sheltered sides of the reefs resulted in the collection of 2048 larvae representing 49 diff...
متن کاملEmbryonic, larval and juvenile development of tropical sea urchin, Diadema setosum
Diadema setosum (Leske, 1778), is one of the common echinoids widely distributed in the Indo-West Pacific Ocean, where it occurs from the Red Sea, Persian Gulf and the east coast of Africa to Japan, Australia and Malaysia. To investigate the developmental basis of morphological changes in embryos and larvae, we documented the ontogeny of D. setosum in a controlled laboratory condition at the In...
