| shallow-water wave lensing in coral reefs: a physical and biological case study. | wave lensing produces the highest level of transient solar irradiances found in nature, ranging in intensity over several orders of magnitude in just a few tens of milliseconds. shallow coral reefs can be exposed to wave lensing during light-wind, clear-sky conditions, which have been implicated as a secondary cause of mass coral bleaching through light stress. management strategies to protect small areas of high-value reef from wave-lensed light stress were tested using seawater irrigation spri ... | 2010 | 21113012 |
| intracolonial variation in toxicity in scleractinian corals. | single colonies of the scleractinian corals lobophyllia corymbosa, favites abdita, favia matthaii, favia stelligera, platygyra daedalea, leptoria phrygia, cyphastrea serailia, hydnophora exesa and astreopora myriophthalma were permanently marked with buoys on the reef flat at heron island. great barrier reef. portions of colonies were removed up to seven times at intervals of two or three months. aqueous extracts of the colony portions were assayed using six bioassay regimes namely, toxicity to ... | 1990 | 1979892 |
| comparative embryology of eleven species of stony corals (scleractinia). | a comprehensive understanding of coral reproduction and development is needed because corals are threatened in many ways by human activity. major threats include the loss of their photosynthetic symbionts (symbiodinium) caused by rising temperatures (bleaching), reduced ability to calcify caused by ocean acidification, increased storm severity associated with global climate change and an increase in predators caused by runoff from human agricultural activity. in spite of these threats, detailed ... | 2013 | 24367633 |
| quantification of coral sperm collected during a synchronous spawning event. | most studies of coral reproductive biology to date have focused on oocyte numbers and sizes. only one (ex situ) study has enumerated sperm numbers, even though these data have multiple potential applications. we quantified total coral sperm and eggs per gamete bundle collected from six species in situ during a synchronous spawning event in singapore. egg-sperm bundles were captured midwater as they floated towards the surface after being released by the colony. for each sample, a semi-transparen ... | 2016 | 27478697 |
| coral-associated bacterial communities on ningaloo reef, western australia. | coral-associated microbial communities from three coral species (pocillopora damicornis, acropora tenuis and favites abdita) were examined every 3 months (january, march, june, october) over a period of 1 year on ningaloo reef, western australia. tissue from corals was collected throughout the year and additional sampling of coral mucus and seawater samples was performed in january. tissue samples were also obtained in october from p. damicornis coral colonies on rottnest island off perth, 1200 ... | 2011 | 21044100 |
| changes in zooxanthellae density, morphology, and mitotic index in hermatypic corals and anemones exposed to cyanide. | sodium cyanide (nacn) is widely used for the capture of reef fish throughout southeast asia and causes extensive fish mortality, but the effect of nacn on reef corals remains debated. to document the impact of cyanide exposure on corals, the species acropora millepora, goniopora sp., favites abdita, trachyphyllia geoffrio, plerogyra sp., heliofungia actinformis, euphyllia divisa, and scarophyton sp., and the sea anemone aiptasia pallida were exposed to varying concentrations of cyanide for varyi ... | 2003 | 12735955 |
