Effects of pCO2 on spatial competition between the corals Montipora aequituberculata and Porites lutea

International Atomic Energy Agency (IAEA) Publications

We tested the hypothesis that ocean acidification (OA) affects spatial competition among scleractinian corals. Competitive ability was evaluated indirectly by linear extension of Porites...

Interactive effects of elevated temperature and CO2 on foraging behavior of juvenile coral reef fish

International Atomic Energy Agency (IAEA) Publications

Two of the major threats to coral reefs are increasing sea surface temperature and ocean acidification, both of which result from rising concentrations of atmospheric carbon dioxide...

Publications

Metabolically-induced pH fluctuations by some coastal calcifiers exceed projected 22nd century ocean acidification: a mechanism for differential susceptibility?

International Atomic Energy Agency (IAEA) Publications

Anthropogenically-mediated decreases in pH, termed ocean acidification (OA), may be a major threat to marine organisms and communities. Research has focussed mainly on tropical coral...

Publications

Calcium carbonate (CaCO3) sediment dissolution under elevated concentrations of carbon dioxide (CO2) and nitrate (NO3−)

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA), attributed to the sequestration of atmospheric carbon dioxide (CO2) into the surface ocean, and coastal eutrophication, attributed in part to land-use change and...

Publications

Ocean acidification hampers sperm-egg collisions, gamete fusion, and generation of Ca 2+ oscillations of a broadcast spawning bivalve, Tegillarca granosa

International Atomic Energy Agency (IAEA) Publications

Although the effect of ocean acidification on fertilization success of marine organisms is increasingly well documented, the underlying mechanisms are not completely understood. The...

Expression of calcification and metabolism-related genes in response to elevated pCO2 and temperature in the reef-building coral Acropora millepora

International Atomic Energy Agency (IAEA) Publications

Declining health of scleractinian corals in response to deteriorating environmental conditions is widely acknowledged, however links between physiological and functional genomic responses...

Impacts of groundwater discharge at Myora Springs (North Stradbroke Island, Australia) on the phenolic metabolism of eelgrass, Zostera muelleri, and grazing by the juvenile rabbitfish, Siganus fuscescens

International Atomic Energy Agency (IAEA) Publications

Myora Springs is one of many groundwater discharge sites on North Stradbroke Island (Queensland, Australia). Here spring waters emerge from wetland forests to join Moreton Bay, mixing...

Ocean acidification causes bleaching and productivity loss in coral reef builders

International Atomic Energy Agency (IAEA) Publications

Ocean acidification represents a key threat to coral reefs by reducing the calcification rate of the major reef framework builders. In addition, acidification is likely to affect the...

Long-term exposure to elevated carbon dioxide does not alter activity levels of a coral reef fish in response to predator chemical cues

International Atomic Energy Agency (IAEA) Publications

ABSTRACT: Levels of dissolved carbon dioxide (CO2) projected to occur in the world's oceans in the near future have been reported to increase swimming activity and impair predator...

Response of subtropical coastal sediment systems of Okinawa, Japan, to experimental warming and high pCO2

International Atomic Energy Agency (IAEA) Publications

Increasing seawater temperatures and CO2 levels associated with climate change affect the shallow marine ecosystem function. In this study, the effects of elevated seawater temperature...

Publications

High CO2 reduces the settlement of a spawning coral on three common species of crustose coralline algae

International Atomic Energy Agency (IAEA) Publications

Concern about the impacts of ocean acidification (OA) on ecosystem function has prompted many studies to focus on larval recruitment, demonstrating declines in settlement and early growth...

A “core-top” screen for trace element proxies of environmental conditions and growth rates in the calcite skeletons of bamboo corals (Isididae)

International Atomic Energy Agency (IAEA) Publications

We test for trace element proxies in the high-magnesium calcite fraction of bamboo coral internodes by comparing environmental conditions and growth rates to the specimen-mean...

Insights from sodium into the impacts of elevated pCO2 and temperature on bivalve shell formation

International Atomic Energy Agency (IAEA) Publications

Ocean acidification and warming are predicted to affect the ability of marine bivalves to build their shells, but little is known about the underlying mechanisms. Shell formation is an...

Publications

Early development of undulated surf clam, Paphia undulate under elevated pCO2

International Atomic Energy Agency (IAEA) Publications

Increasing atmospheric CO2 can decrease the seawater pH and carbonate ions, which may adversely affect the larval survival of calcareous animals. In this study, we simulated future...

Nutrient pollution disrupts key ecosystem functions on coral reefs

International Atomic Energy Agency (IAEA) Publications

There is a long history of examining the impacts of nutrient pollution and pH on coral reefs. However, little is known about how these two stressors interact and influence coral reef...

Potential future coral habitats around Japan depend strongly on anthropogenic CO2 emissions

International Atomic Energy Agency (IAEA) Publications

Using the results from the NCAR CSM1.4-coupled global carbon cycle–climate model under the Intergovernmental Panel on Climate Change (IPCC) emission scenarios SRES A2 and B1, we estimated...

Isolation of high-level-CO2-preferring Picochlorum sp. strains and their biotechnological potential

International Atomic Energy Agency (IAEA) Publications

Production of CO2-tolerant microalgae have received much attention as well as physicochemical fixation of CO2 in industrial flue gas. Although many microalgae that are tolerant to high...

Dissolution: the Achilles' heel of the triton shell in an acidifying ocean

International Atomic Energy Agency (IAEA) Publications

Ocean acidification is expected to negatively impact many calcifying marine organisms by impairing their ability to build their protective shells and skeletons, and by causing dissolution...
