Background The rising temperature of the world's oceans has become a major threat to coral reefs globally as severity and frequency mass bleaching mortality events increase. In 2005, high ocean temperatures in tropical Atlantic Caribbean resulted most severe event ever recorded basin. Methodology/Principal Findings Satellite-based tools provided warnings for reef managers scientists, guiding both timing location researchers' field observations anomalously warm conditions developed spread...
The early effects of heat stress on the photosynthesis symbiotic dinoflagellates (zooxanthellae) within tissues a reef‐building coral were examined using pulse‐amplitude‐modulated (PAM) chlorophyll fluorescence and photorespirometry. Exposure Stylophora pistillata to 33 34 °C for 4 h resulted in (1) development strong non‐photochemical quenching (qN) signal, (2) marked decreases photosynthetic oxygen evolution, (3) optimal quantum yield ( F v / m ) photosystem II (PSII). Quantum decreased...

To examine algal (= zooxanthellae) regulation and control, the factors determining densities in hard corals, zooxanthellae mitotic index release rates were regularly determined branch tips from a colony of staghorn coral, Acropora formosa , recovering coral ‘bleaching’ event (the stress–related dissociation coral–algal symbiosis). Mathematical models based upon density–dependent decreases division frequency increases during post–bleaching recovery period accurately predict observed (≈ 20...
ABSTRACT The photochemical efficiency of symbiotic dinoflagellates within the tissues two reef‐building corals in response to normal and excess irradiance at water temperatures < 30 °C were investigated using pulse amplitude modulated (PAM) chlorophyll fluorescence techniques. Dark‐adapted F v / m showed clear diurnal changes, decreasing a low solar noon increasing afternoon. However, also drifted downwards night or prolonged darkness, increased rapidly during early morning twilight. This...

Abstract The deep reef refugia hypothesis proposes that reefs can act as local recruitment sources for shallow following disturbance. To test this hypothesis, nine polymorphic DNA microsatellite loci were developed and used to assess vertical connectivity in 583 coral colonies of the Caribbean depth‐generalist Montastraea cavernosa . Samples collected from three depth zones (≤10, 15–20 ≥25 m) at sites Florida (within Upper Keys, Lower Keys Dry Tortugas), Bermuda, U.S. Virgin Islands....
Abstract To date, most assessments of coral connectivity have emphasized long-distance horizontal dispersal propagules from one shallow reef to another. The extent vertical connectivity, however, remains largely understudied. Here, we used newly-developed and existing DNA microsatellite loci for the brooding Porites astreoides assess patterns in 590 colonies collected three depth zones (≤10 m, 15–20 m ≥25 m) at sites Florida, Bermuda U.S. Virgin Islands (USVI). We also tested whether...
Abstract Understanding pressure pathways and their cumulative impacts is critical for developing effective environmental policy. For coral reefs, wide spread bleaching resulting from global warming occurring concurrently with local pressures, such as increases in suspended sediments through coastal development. Here we examine the relative importance of sediment dredging on corals evidence synergistic or antagonistic effects between thermal stress. We show that low to moderate reductions...

Successful recruitment in corals is important for the sustenance of coral reefs, and considered a demographic bottleneck recovery reef populations following disturbance events. Yet several factors influence larval settlement behaviour, here we quantified thresholds associated with light attenuation accumulated sediments on substrates. Sediments deposited calcareous red algae (CRA) directly indirectly impacted patterns. Although not avoiding direct contact, Acropora millepora larvae were very...
Dredging in the marine environment to create and maintain safe, navigable shipping channels, subsequent disposal of material at sea dredge placement sites (spoil grounds) can generate large quantities suspended sediment that impact upon epibenthic communities. For sensitive taxa such as hard corals, understanding mechanisms mortality spatial scale over which these occur is critically important for prediction purposes, management dredging using zonation schemes, also public perception. We...
