Phytoplankton do not produce carbon-rich organic matter in high CO2 oceans

International Atomic Energy Agency (IAEA) Publications

The ocean is a substantial sink for atmospheric carbon dioxide (CO2) released as a result of human activities. Over the coming decades the dissolved inorganic C concentration in the...

Publications

Boosted nutritional quality of food by CO2 enrichment fails to offset energy demand of herbivores under ocean warming, causing energy depletion and mortality

International Atomic Energy Agency (IAEA) Publications

The CO2-boosted trophic transfer from primary producers to herbivores has been increasingly discovered at natural CO2 vents and in laboratory experiments. Despite the emerging knowledge...

Publications

Uranium in larval shells as a barometer of molluscan ocean acidification exposure

International Atomic Energy Agency (IAEA) Publications

As the ocean undergoes acidification, marine organisms will become increasingly exposed to reduced pH, yet variability in many coastal settings complicates our ability to accurately...

Predicted impact of ocean acidification on a marine invertebrate: elevated CO2 alters response to thermal stress in sea urchin larvae

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA) and the biological consequences of altered seawater chemistry have emerged as a significant environmental threat to healthy marine ecosystems. Because a more...

Publications

Coral reefs and people in a high-CO2 world: where can science make a difference to people?

International Atomic Energy Agency (IAEA) Publications

Reefs and People at Risk Increasing levels of carbon dioxide in the atmosphere put shallow, warm-water coral reef ecosystems, and the people who depend upon them at risk from two key...

Effect of pH and temperature on antioxidant responses of the thick shell mussel Mytilus coruscus

International Atomic Energy Agency (IAEA) Publications

This study evaluated the combined effects of seawater pH decrease and temperature increase on the activity of antioxidant enzymes in the thick shell mussel Mytilus coruscus, an ecological...

Publications

An aposymbiotic primary coral polyp counteracts acidification by active pH regulation

International Atomic Energy Agency (IAEA) Publications

Corals build their skeletons using extracellular calcifying fluid located in the tissue-skeleton interface. However, the mechanism by which corals control the transport of calcium and...

Publications

Deducing acidification rates based on short-term time series

International Atomic Energy Agency (IAEA) Publications

We show that, statistically, the simple linear regression (SLR)-determined rate of temporal change in seawater pH ($β$pH), the so-called acidification rate, can be expressed as a linear...

Publications

Ecological effects of ocean acidification and habitat complexity on reef-associated macroinvertebrate communities

International Atomic Energy Agency (IAEA) Publications

The ecological effects of ocean acidification (OA) from rising atmospheric carbon dioxide (CO2) on benthic marine communities are largely unknown. We investigated in situ the consequences...

Publications

Symbiodinium mitigate the combined effects of hypoxia and acidification on a non-calcifying cnidarian

International Atomic Energy Agency (IAEA) Publications

Anthropogenic nutrient inputs enhance microbial respiration within many coastal ecosystems, driving concurrent hypoxia and acidification. During photosynthesis, Symbiodinium spp., the...

Perceptions of climate change and adaptation responses in a local community: the Barwon Estuary Complex, Victoria

International Atomic Energy Agency (IAEA) Publications

The climate change focus in Australia has shifted from mitigation to adaptation with an emphasis on place-specific case studies. The Barwon Estuary Complex (BEC) on the Bellarine...

Publications

Responses of neurogenesis and neuroplasticity related genes to elevated CO2 levels in the brain of three teleost species

International Atomic Energy Agency (IAEA) Publications

The continuous increase of anthropogenic CO2 in the atmosphere resulting in ocean acidification has been reported to affect brain function in some fishes. During adulthood, cell...

Publications

Internal pH regulation facilitates in situ long-term acclimation of massive corals to end-of-century carbon dioxide conditions.

International Atomic Energy Agency (IAEA) Publications

The resilience of tropical corals to ocean acidification depends on their ability to regulate the pH within their calcifying fluid (pHcf). Recent work suggests pHcf homeostasis under...

Influence of climate and land use in carbon biogeochemistry in lower reaches of rivers in central southern Chile: Implications for the carbonate system in river-influenced rocky shore environments: Riverine contributions to coastal areas

International Atomic Energy Agency (IAEA) Publications

Freshwater discharge affects the biogeochemistry of river-influenced nearshore environments by contributing with carbon and nutrients. An increase in human activities in river basins may...

Anthropogenic carbon distribution in the eastern South Pacific Ocean

International Atomic Energy Agency (IAEA) Publications

We present results of the CO2/carbonate system from the BIOSOPE cruise in the Eastern South Pacific Ocean, in an area not sampled previously. In particular, we present estimates of the...

Toxic dinoflagellate blooms of in Chilean fjords: a resilient winner from climate change

International Atomic Energy Agency (IAEA) Publications

Exposure of the toxigenic dinoflagellate Alexandrium catenella to variations in pCO2/pH, comparable to current and near-future levels observed in Southern Chilean fjords, revealed...

Publications

Habitat preferences of coral-associated fishes are altered by short-term exposure to elevated CO2

International Atomic Energy Agency (IAEA) Publications

Rising atmospheric carbon dioxide (CO2) concentrations are causing additional CO2 to be absorbed by the oceans. Recent studies show that exposure to elevated CO2 causes olfactory...

Near-future ocean acidification enhances the feeding rate and development of the herbivorous juveniles of the crown-of-thorns starfish, Acanthaster planci

International Atomic Energy Agency (IAEA) Publications

Population outbreaks of the corallivorous crown-of-thorns starfish, Acanthaster planci, are a major contributor to the decline in coral reef across the Indo-Pacific. The success of A....
