Effects of nonlocal turbulence on the mass transfer of dissolved species to reef corals
Effects of nonlocal turbulence the mass transfer dissolved species to reef corals
font style='font-size:12px;'>
2014/4/22
We examined the importance of nonlocal turbulence to the mass transfer of dissolved species from both cylinders and models of reef coral. Solid gypsum cylinders and gypsum-coated model coral were diss...
Seascape Genetics: A Coupled Oceanographic-Genetic Model Predicts Population Structure of Caribbean Corals
Seascape Genetics Model Predicts Population
font style='font-size:12px;'>
2015/12/16
Population genetics is a powerful tool for measuring
important larval connections between marine populations[1–4]. Similarly, oceanographic models based on
environmental data can simulate particle m...
The ecological distribution and comparative photobiology of symbiotic dinoflagellates from reef corals in Belize: Potential implications for coral bleaching
ecological distribution comparative photobiology symbiotic dinoflagellates reef corals in Belize coral bleaching
font style='font-size:12px;'>
2014/5/4
The photobiology and distribution of dinoflagellates in the genus Symbiodinium was investigated for eight common reef coral species over a depth range of 1-25 m on a coral reef in Belize. The genetic ...
Effects of irradiance, flow, and colony pigmentation on the temperature microenvironment around corals: Implications for coral bleaching?
Effects of irradiance fl ow colony pigmentation
font style='font-size:12px;'>
2014/4/23
Experiments were conducted to determine the effects of colony pigmentation, irradiance, and flow on the temperature microenvironment that corals experience in shallow water. The warming of colon...
Primary U distribution in scleractinian corals and its implications for U series dating
uranium diagenesis coral dating.
font style='font-size:12px;'>
2014/4/9
In this study we use microsampling techniques to explore diagenetic processes in carbonates. These processes are important as they can affect the accuracy of U series chronometry. Fission track maps o...
The effects of waves and morphology on mass transfer within branched reef corals
morphology mass transfer
font style='font-size:12px;'>
2014/5/4
Rates of mass transfer in coral reefs are governed both by the physical flow environment and the morphology of the coral. Laboratory experiments were conducted to estimate mass transfer in unidirectio...
Aeration of corals by sleep-swimming fish

font style='font-size:12px;'>
2014/5/19
The morphology of branching corals effectively blocks impinging currents. Weak flows in the colony’s inner
sections can hinder some of the corals’ basic physiological functions. At night, high ...
Low symbiont diversity in southern Great Barrier Reef corals relative to those of the Caribbean
Low symbiont diversity southern Great Barrier Reef corals relative the Caribbean
font style='font-size:12px;'>
2014/5/21
The specific identity of endosymbiotic dinoflagellates (Symbiodinium spp.) from most zooxanthellate corals is unknown. In a survey of symbiotic cnidarians from the southern Great Barrier Reef (GBR), 2...
Stable isotopes in deep-sea corals and a new mechanism for “vital effects”
Stable isotopes deep-sea corals new mechanism vital effects
font style='font-size:12px;'>
2014/4/9
Offsets from isotopic equilibrium in biogenic carbonates have complicated paleoclimate reconstructions for decades. A new archive of climate, deep-sea corals, is used to evaluate the calcification pro...
Contribution of fluorescence to the spectral signature and perceived color of corals
Contribution of fluorescence spectral signature perceived color of corals
font style='font-size:12px;'>
2014/5/19
Solar-induced fluorescence from pigments in the host tissues of reef corals can make a significant contribution to their spectral signature and can affect their apparent color as perceived by a human ...
Comparative analysis of energy allocation to tissue and skeletal growth in corals
energy allocation tissue and skeletal growth corals
font style='font-size:12px;'>
2014/5/26
In aquatic invertebrates that form exoskeletons, the partitioning of energy between skeletal and tissue growth is an important tradeoff, especially under resource limitation or physiological stress. H...
Photoreceptors in the cnidarian hosts allow symbiotic corals to sense blue moonlight
Photoreceptors cnidaria hosts symbiotic corals sense blue moonlight
font style='font-size:12px;'>
2014/5/26
In many species of symbiotic corals, spawning occurs synchronously several nights after the full moon. This process is correlated with the level of lunar irradiance, but the mechanism by which these c...

RADIOCARBON DATING DEEP-SEA CORALS
font style='font-size:12px;'>
2014/4/9
Deep-sea corals are a promising new archive of paleoclimate. Coupled radiocarbon and U-series dates allow 14C to be used as a tracer of ocean circulation rate in the same manner as it is used in the m...
