Coral Reefs and Biodiversity:A Critical and Threatened Relationship
Coral Reefs Biodiversity Threatened Relationship
2015/8/13
The importance of coral reef ecosystems may be seen in their numerous ecological, aesthetic, economic, and cultural functions. Atoll and barrier reef islanders recognize that healthy reefs are essenti...
Intense Benthic Grazing on Phytoplankton in Coral Reefs Revealed Using the Control Volume Approach
Coral Reefs Revealed Control Volume Approach
2015/8/5
What is our international investment in oceanography, and how has it changed over the years? Two seemingly simple questions that have daunted our community repeatedly. The first of these two questions...
The Moorea Coral Reef Long Term Ecological Research program affords a unique opportunity to study the implications of ocean acidification (OA) for coral reefs, as ongoing ecological and physical monit...
Coral Tissue Thickness as a Bioindicator of Mine-Related Turbidity Stress on Coral Reefs at Lihir Island,Papua New Guinea
Coral Tissue Thickness Bioindicator Mine-Related Turbidity Stress Coral Reefs Lihir Island Papua New Guinea
2015/7/15
Work described here assessed the feasibility of using variations in tissue thickness in massive Porites corals as a bioindicator for mine-related sediment stress. We examined parameters influencing co...
Ocean acidification hot spots: Spatiotemporal dynamics of the seawater CO2 system of eastern Pacific coral reefs
Ocean acidification hot spots Spatiotemporal dynamics the seawater CO2 system eastern Pacific coral reefs
2014/4/16
Seawater CO2system dynamics were assessed from eastern Pacific reef sites in Panama ′ over 5 consecutive years(2003–2008) and twice in the Gala ′ pagos Islands (2003 and 2009). The seawater CO2system ...
Coral Reefs and Ocean Acidification
Coral reef ecosystems ocean acidification calcium carbonate reef-forming organisms
2015/7/6
Coral reefs were one of the first ecosystems to be recognized as vulnerable to ocean acidification. To date, most scientific investigations into the effects of ocean acidification on coral reefs have ...
Decline of coral reefs during late Paleocene to early Eocene global warming
coral reefs late Paleocene early Eocene global warming
2009/10/22
Since the 1980s the frequency of warming events has intensified and simultaneously widespread coral bleaching, and enhanced coral mortality have been observed. Yet, it remains unpredictable how tropic...
Hydrodynamic forces on larvae affect their settlement on coral reefs in turbulent, wavedriven flow
Hydrodynamic forces affect their settlement
2014/4/17
This study investigates a key aspect of how ambient flow affects the recruitment of water-dispersed marine larvae
onto benthic substrata: the sweeping away of larvae that have landed on surfaces. Thr...
Sediment-mediated suppression of herbivory on coral reefs: Decreasing resilience to rising sea-levels and climate change?
Sediment-mediated suppression of herbivory coral reefs Decreasing resilience rising sea-levels climate change
2014/4/21
We describe a mechanistic basis for maintaining an alternative degraded stable state on coral reefs: sediment-laden algal turfs. Using remote underwater video cameras we quantified rates of herbivory ...

Possible effects of downwelling on the recruitment of coral reef fishes to the Eilat (Red Sea) coral reefs
coral reef fishes the Eilat coral reefs
2014/4/21
We compared water current measurements with data on the recruitment of reef fishes to a coral reef in Eilat, Red Sea for two consecutive recruitment seasons. There was a clear correlation between the ...
Chemical warfare on coral reefs: Sponge metabolites differentially affect coral symbiosis in situ
Chemical warfare on coral reefs Sponge metabolites differentially coral symbiosis in situ
2014/4/23
Coral reef ecosystems are characterized by high species diversity and intense levels of biotic interaction, particularly competition for space among sessile benthic invertebrates. Using in situ pulse ...
Climate Change, Human Impacts, and the Resilience of Coral Reefs
Coral Reefs Human Impacts
2015/12/16
The diversity, frequency, and scale of human impacts on coral reefs are increasing to the
extent that reefs are threatened globally. Projected increases in carbon dioxide and
temperature over the ne...
Episodic nutrient transport to Florida coral reefs

2014/5/21
This study documents the changes in nutrient fluxes associated with internal tidal bores arriving on Florida Keys
coral reefs and points to biological use of subthermocline nitrate brought onsh...
