Zooplankton reside in a constantly flowing environment. However, information about their response to ambient flow has remained elusive, because of the difficulties following individual motions these minute, nearly transparent animals ocean. Using three-dimensional acoustic imaging system, we tracked >375,000 zooplankters at two coastal sites Red Sea. Resolution motion from that water showed effectively maintained depth by swimming against upwelling and downwelling currents moving rates up...
Tropical scleractinian corals are particularly vulnerable to global warming as elevated sea surface temperatures (SSTs) disrupt the delicate balance between coral host and their algal endosymbionts, leading symbiont expulsion, mass bleaching mortality. While satellite sensing of SST has proved a reliable predictor at regional scale, there large deviations in severity mortality on local scale that poorly understood. Here, we show internal waves play major role explaining patterns Andaman Sea....
Marine animal forests (MAFs) are benthic ecosystems characterised by biogenic three-dimensional structures formed suspension feeders such as corals, gorgonians, sponges and bivalves. They comprise highly diversified communities among the most productive in world's oceans. However, MAFs decline due to global local stressors that threaten survival growth of their foundational species associated biodiversity. Innovative scalable interventions needed address degradation increase resilience under...
Abstract Ice retreat in West Antarctica and Antarctic Peninsula has led to important changes seafloor communities gains benthic blue carbon. In most of the Antarctic, however, sea ice increased between 1970s 2014, but its effects on benthos remain largely unexplored. Here, we provide a 1988–2014 record macro- megafauna from north-eastern Weddell Sea shelf, where biomass decreased by two thirds composition shifted suspension feeders deposit feeders. Concomitant increases sea-ice cover suggest...
Biofilms play an important role as a settlement cue for invertebrate larvae and significantly contribute to the nutrient turnover in aquatic ecosystems. Nevertheless, little is known about how biofilm community structure generally responds environmental changes. This study aimed identify patterns of bacterial dynamics coral reef biofilms response associated macrofouling structure, microhabitat (exposed vs. sheltered), seasonality, eutrophication. Settlement tiles were deployed at four reefs...
Following up on previous investigations the stress resistance of corals, this study assessed trophic plasticity coral Stylophora subseriata in Spermonde Archipelago (Indonesia) along an eutrophication gradient. Trophic was terms lipid content and fatty acid composition holobiont relative to its plankton (50-300 μm) food as well zooxanthellae density, lipid, FA chlorophyll a content. A cross-transplantation experiment carried out for 1.5 months order assess potential corals. Corals, which...
Cold-water corals provide an important habitat for a rich fauna along the continental margins and slopes. Although these azooxanthellate are considered particularly sensitive to ocean acidification, their responses natural variations in pH aragonite saturation largely unknown due difficulty of studying ecology deep waters. Previous SCUBA investigations have shown exceptionally shallow population cold-water coral Desmophyllum dianthus near-surface waters Comau Fjord, stratified 480 m basin...
As a response to ocean warming, shifts in fish species distribution and changes production have been reported, that partly attributed temperature effects on the physiology of animals. The Southern Ocean hosts some most rapidly warming regions earth Antarctic organisms are reported be especially sensitive. While cellular molecular organismic levels appear to, at least partially, compensate for elevated temperatures, consequences acclimation whole organism often less clear. Growth reproduction...
Ocean warming is a major threat for coral reefs causing widespread bleaching and mortality. Potential refugia are thus crucial survival. Exposure to large-amplitude internal waves (LAIW) mitigated heat stress ensured survival recovery during after an extreme anomaly. The physiological status of two common corals, Porites lutea Pocillopora meandrina, was monitored in host symbiont traits, response LAIW-exposure throughout the unprecedented 2010 anomaly Andaman Sea. LAIW-exposed corals both...
Abstract The exchange of metabolites between environment and coral tissue depends on the flux across diffusive boundary layer (DBL) surrounding tissue. Cilia covering have been shown to create vortices that enhance mixing in DBL stagnant water. To study role cilia under simulated ambient currents, we designed a new light-sheet microscopy based flow chamber setup. Microparticle velocimetry was combined with high-resolution oxygen profiling Porites lutea varying current light conditions...
Most tropical corals live in symbiosis with Symbiodiniaceae algae whose photosynthetic production of oxygen (O2) may lead to excess O2 the diffusive boundary layer (DBL) above coral surface. When flow is low, cilia-induced mixing DBL vital remove and prevent oxidative stress that bleaching mortality. Here, we combined particle image velocimetry using O2-sensitive nanoparticles (sensPIV) chlorophyll (Chla)-sensitive hyperspectral imaging visualize microscale distribution dynamics ciliary...
Comau Fjord is a stratified Chilean Patagonian characterized by shallow brackish surface layer and >400 m of aragonite-depleted subsurface waters. Despite the energetic burden low aragonite saturation levels to calcification, harbours dense populations cold-water corals (CWC). While this paradox has been attributed rich supply zooplankton, supporting abundance biomass data are so far lacking. In study, we investigated seasonal diel changes zooplankton community over entire water column....
