The inshore reefs of the Great Barrier Reef (GBR) have undergone significant declines in water quality following European settlement (approx. 1870 AD). However, direct evidence impacts on coral assemblages is limited by a lack historical baselines prior to onset modern monitoring programmes early 1980s. Through palaeoecological reconstructions, we report previously undocumented collapse Acropora at Pelorus Island (central GBR). High-precision U-series dating dead fragments indicates that...
Abstract Large benthic foraminifera are major carbonate components in tropical platforms, important producers, stratigraphic tools and powerful bioindicators (proxies) of environmental change. The application large coral reef environments has gained considerable momentum recent years. These modern ecological assessments often carried out by micropalaeontologists or ecologists with expertise the identification foraminifera. However, have been under‐represented favour macro reef‐builders, for...
Abstract The iconic Great Barrier Reef (GBR) experienced mass coral bleaching in early 2024. In the southern GBR, heat stress triggered severe and widespread to levels not previously recorded impacted a diverse range of genera at One Tree (OTR). Over 161 d, we tracked health 462 colonies from heatwave peak autumn winter cooling. February April, 66% 80% were bleached, respectively. By May, 44% bleached dead 53% July. July, 31% still 16% recovered. Goniopora developed black band disease...
Thermal stress reduces pocilloporid coral resilience to ocean acidification by impairing control over calcifying fluid chemistry.
Glomalin, an arbuscular mycorrhizal protein component of soil, can be used as indicator terrigenous‐derived carbon. We measured glomalin in sediments using the terrestrial end‐member a reference four coastal settings: (1) intertidal seagrass meadows distributed over rainfall gradient, (2) inshore and offshore from mouth river, (3) coral reefs at various distances shore, (4) wetlands with varying levels groundwater influence. Across meadow increased sites high mean annual during wet season (...
The combination of global and local stressors is leading to a decline in coral reef health globally. In the case eutrophication, increased concentrations dissolved inorganic nitrogen (DIN) phosphorus (DIP) are largely attributed land use changes. From perspective, atmospheric CO2 levels not only contributing warming but also ocean acidification (OA). Both eutrophication OA have serious implications for calcium carbonate production dissolution among calcifying organisms. particular, benthic...
Reef-dwelling calcifiers face numerous environmental stresses associated with anthropogenic carbon dioxide emissions, including ocean acidification and warming. Photosymbiont-bearing calcifiers, such as large benthic foraminifera, are particularly sensitive to climate change. To gain insight into their responses near-future conditions, Amphistegina lobifera from the Gulf of Aqaba were cultured under three pCO2 conditions (492, 963, 3182 ppm) crossed two temperature (28 °C, 31 °C) for months....
Ocean acidification (OA) is a global problem with profoundly negative environmental, social and economic consequences. From governance perspective, there need to ensure coordinated effort directly address it. This study reviews 90 legislative documents from 17 countries the European Economic Area (EEA) UK that primarily border sea. The primary finding this national policies legislation addressing OA at best uncoordinated. Although acknowledged higher levels of governance, its status as an...
Abstract Strongly influenced by seasonal and interannual (i.e. El Niño‐Southern Oscillation) upwelling, the equatorial setting of Galápagos Archipelago is divided into well‐defined temperature, nutrient calcium carbonate saturation (Ω aragonite ) regions. To understand relationship between oceanographic properties sediment grain associations, size, content components from sea floor surface samples were analysed, representing main geographical regions Archipelago. The shallow‐water rocky...
Shallow marine ecosystems naturally experience fluctuating physicochemical conditions across spatial and temporal scales. Widespread coral-bleaching events, induced by prolonged heat stress, highlight the importance of how duration frequency thermal stress influence adaptive physiology photosymbiotic calcifiers. Large benthic foraminifera harboring algal endosymbionts are major tropical carbonate producers bioindicators ecosystem health. Like corals, they sensitive to bleach at temperatures...
Coral reefs persist in an accretion-erosion balance, which is critical for understanding the natural variability of sediment production, reef accretion, and their effects on carbonate budget. Bioerosion (i.e. biodegradation substrate) encrustation calcified overgrowth influence budget ecological functions coral reefs, by substrate formation/consolidation/erosion, food availability nutrient cycling. This study investigates settlement succession change bioeroding encrusting calcifying...

Abstract The proliferation of key marine ecological engineers and carbonate producers often relies on their association with photosymbiotic algae. Evaluating stress responses these organisms is important to predict fate under future climate projections. Physiological approaches are limited in ability resolve the involved molecular mechanisms attribute effects host or symbiont, while probing partitioning proteins cannot be applied where symbiont small physically separated. Here we apply a...
In order to help predict the effects of anthropogenic stressors on shallow water carbonate environments, it is important focus research regions containing natural oceanographic gradients, particularly with respect interactions between oceanography and ecologically sensitive producers. The Galápagos Archipelago, an island chain in eastern equatorial Pacific, spans a nutrient, pH, temperature gradient due interaction several major ocean currents. Further, region heavily impacted by El...
Increasing anthropogenic carbon dioxide is predicted to cause declines in ocean pH and calcium carbonate saturation state over the coming centuries, making it potentially harder for marine calcifiers build their shells skeletons. One mechanism of resilience acidification an organism's ability regulate and, thus, state, at its site calcification. This has received detailed study scleractinian corals but relatively understudied other taxonomic groups that are vulnerable acidification, such as...
Corals are globally important calcifiers that exhibit complex responses to anthropogenic warming and acidification. Although coral calcification is supported by high seawater pH, photosynthesis the algal symbionts of zooxanthellate corals can be promoted elevated pCO2. To investigate mechanisms underlying corals’ global change, three species tropical (Stylophora pistillata, Pocillopora damicornis, Seriatopora hystrix) one asymbiotic cold-water (Desmophyllum pertusum, syn. Lophelia pertusa)...
Photosymbiotic scleractinian corals are major bioengineers in tropical coastal waters, where they build structurally complex geological features and provide substrata for a manifold of macro microhabitats. On local scale, ecological competition physical parameters - natural as well human-derived, alter species richness, biodiversity, morphological adaptation on coral reefs. Here, we compared four reefs the Zanzibar Archipelago at different distances from Stone Town under management regimes....
Abstract The El Niño–Southern Oscillation (ENSO) is a periodic climatic and oceanic event caused by sea-surface temperature nutrient anomalies over the eastern tropical Pacific Ocean (ETP). Recurring ENSO events have significant impact on climate ecosystems of circum-Pacific region. In marine realm, known for altering patterns, affecting pelagic food chain, causing widespread bleaching corals due to stress. potential impacts shallow benthic as whole, however, are poorly understood. Here, we...
