effects of mechanical fracturing and experimental trampling on hawaiian corals.	in situ trampling occurred under experimental conditions to quantify the differences in the responses to anthropogenic trampling in four dominant species of hawaiian corals, porites compressa, porites lobata, montipora capitata, and pocillopora meandrina. trampling was simulated daily for a period of nine days at which time further breakage was minimal. forty treatment colonies produced 559 fragments. trampling was followed by an 11-month recovery period. coral colony and fragment mortality was ...	2003	12592453
a deep-sea slant on the molecular phylogeny of the scleractinia.	lophelia pertusa and madrepora oculata are azooxanthellate corals with nearly cosmopolitan distributions. they form cold-water reefs in the upper bathyal zone on continental margins and offshore banks [a.d. rogers, int. rev. hydrobiol. 84 (1999) 315]. lophelia is classified in the family caryophylliidae and madrepora in the family oculinidae, both on the basis of skeletal morphology. recent molecular studies of the scleractinians have given a new insight into the evolutionary history of this gro ...	2004	15022767
patterns of genetic variation do not correlate with geographical distance in the reef-building coral pocillopora meandrina in the south pacific.	dispersal may be a critical factor in the ability of reef-building corals to recover after major disturbances. we studied patterns of geographical structure using four microsatellite markers in seven south pacific populations of pocillopora meandrina, a major coral species from polynesia. variation within populations showed evidence of heterozygote deficiency. genetic differentiation between populations was detected at a large scale (2000 km) between the tonga and the society islands. within the ...	2005	15910311
evaluation of thermal acclimation capacity in corals with different thermal histories based on catalase concentrations and antioxidant potentials.	colonies of pocillopora damicornis from kaneohe bay and colonies of pocillopora meandrina from a thermal outfall site and a control site at kahe were exposed to three different temperatures (29, 32 and 33 degrees c) in outdoor aquaria on running water tables for five days. samples (n=3) were taken from each treatment at 0800, 1200 and 1600 h. elisas using catalase antibodies and ferric reducing/antioxidant potential (frap) assays were run on the samples to determine how antioxidant levels change ...	2006	16580241
embryonic development in two species of scleractinian coral embryos: symbiodinium localization and mode of gastrulation.	reef-building scleractinian corals widely engage in symbiotic relationships with symbiodinium dinoflagellates (zooxanthellae), which reside inside cells of the gastrodermis. in most cases, sexually produced larvae acquire their symbionts from the environment in the early developmental stages preceding settlement; however, some scleractinian corals maternally "seed" their oocytes with symbionts, and these symbionts are reported to be restricted to the gastrodermis at the time of its formation (ga ...	2007	17651360
the onset of microbial associations in the coral pocillopora meandrina.	associations between healthy adult reef-building corals and bacteria and archaea have been observed in many coral species, but the initiation of their association is not understood. we investigated the onset of association between microorganisms and pocillopora meandrina, a coral that vertically seeds its eggs with symbiotic dinoflagellates before spawning. we compared the bacterial communities associated with prespawned oocyte bundles, spawned eggs, and week old planulae using multivariate anal ...	2009	19242535
betaines and dimethylsulfoniopropionate as major osmolytes in cnidaria with endosymbiotic dinoflagellates.	most marine invertebrates and algae are osmoconformers whose cells accumulate organic osmolytes that provide half or more of cellular osmotic pressure. these solutes are primarily free amino acids and glycine betaine in most invertebrates and small carbohydrates and dimethylsulfoniopropionate (dmsp) in many algae. corals with endosymbiotic dinoflagellates (symbiodinium spp.) have been reported to obtain from the symbionts potential organic osmolytes such as glycerol, amino acids, and dmsp. howev ...	2010	19922288
production of a reference transcriptome and a transcriptomic database (pocilloporabase) for the cauliflower coral, pocillopora damicornis.	abstract: background: motivated by the precarious state of the world's coral reefs, there is currently a keen interest in coral transcriptomics. by identifying changes in coral gene expression that are triggered by particular environmental stressors, we can begin to characterize coral stress responses at the molecular level, which should lead to the development of more powerful diagnostic tools for evaluating the health of corals in the field. furthermore, the identification of genetic variants ...	2011	22126435
