Variable responses of temperate calcified and fleshy macroalgae to elevated CO2 and warming

International Atomic Energy Agency (IAEA) Publications

Anthropogenic carbon dioxide (CO2) emissions simultaneously increase ocean temperatures and reduce ocean surface pH, a process termed ocean acidification (OA). OA is expected to...

Acidification at the surface in the East Sea: a coupled climate-carbon cycle model study

International Atomic Energy Agency (IAEA) Publications

This modeling study investigates the impacts of increasing atmospheric CO2 concentration on acidification in the East Sea. A historical simulation for the past three decades (1980 to...

Complex and interactive effects of ocean acidification and temperature on epilithic and endolithic coral-reef turf algal assemblages

International Atomic Energy Agency (IAEA) Publications

Turf algal assemblages are ubiquitous primary producers on coral reefs, but little is known about the response of this diverse group to ocean acidification (OA) across different...

Spatial patterns of Anchoveta (Engraulis ringens) eggs and larvae in relation to pCO2 in the Peruvian upwelling system

International Atomic Energy Agency (IAEA) Publications

Large and productive fisheries occur in regions experiencing or projected to experience ocean acidification. Anchoveta (Engraulis ringens) constitute the world's largest single-species...

Putting prey and predator into the CO2 equation – qualitative and quantitative effects of ocean acidification on predator–prey interactions

International Atomic Energy Agency (IAEA) Publications

Little is known about the impact of ocean acidification on predator–prey dynamics. Herein, we examined the effect of carbon dioxide (CO2) on both prey and predator by letting one...

Impact of ocean acidification on phytoplankton assemblage, growth, and DMS production following Fe-dust additions in the NE Pacific high-nutrient, low-chlorophyll waters

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA) is likely to have an effect on the fertilizing potential of desert dust in high-nutrient, low-chlorophyll oceanic regions, either by modifying iron (Fe)...

Publications

Warmer more acidic conditions cause decreased productivity and calcification in subtropical coral reef sediment-dwelling calcifiers

International Atomic Energy Agency (IAEA) Publications

The effects of elevated CO2 and temperature on photosynthesis and calcification in the calcifying algae Halimeda macroloba and Halimeda cylindracea and the symbiont-bearing benthic...

Publications

CO2-driven ocean acidification reduces larval feeding efficiency and change food selectivity in the mollusk Concholepas concholepas

International Atomic Energy Agency (IAEA) Publications

We present experimental data obtained from an experiment with newly hatched veliger larvae of the gastropod Concholepas concholepas exposed to three pCO2 levels. Egg capsules were...

Publications

Future herbivory: the indirect effects of enriched CO2 may rival its direct effects

International Atomic Energy Agency (IAEA) Publications

Variation in rates of herbivory may be driven by direct effects of the abiotic environment on grazers, as well as indirect effects mediated by their food. Disentangling these direct and...

Short- and long-term conditioning of a temperate marine diatom community to acidification and warming

International Atomic Energy Agency (IAEA) Publications

Ocean acidification and greenhouse warming will interactively influence competitive success of key phytoplankton groups such as diatoms, but how long-term responses to global change will...

Growing up in the temperate zone: age, growth, calcification and carbonate mineralogy of Melicerita chathamensis (Bryozoa) in southern New Zealand

International Atomic Energy Agency (IAEA) Publications

The cheilostome bryozoan Melicerita chathamensis from the continental shelf around southern New Zealand is unusual in having macroscopic annual growth checks. It thus presents an...

Impacts of near future sea surface pH and temperature conditions on fertilisation and embryonic development in Centrostephanus rodgersii from northern New Zealand and northern New South Wales, Australia

International Atomic Energy Agency (IAEA) Publications

Oceans are warming and becoming more acidic. While higher temperature and lower pH can have negative effects on fertilisation and development of marine invertebrates, warming may...

Ocean acidification and global warming impair shark hunting behaviour and growth

International Atomic Energy Agency (IAEA) Publications

Alterations in predation pressure can have large effects on trophically-structured systems. Modification of predator behaviour via ocean warming has been assessed by laboratory...

Effects of ocean acidification on the metabolic rates of three species of bivalve from southern coast of China

International Atomic Energy Agency (IAEA) Publications

Oceanic uptake of anthropogenic carbon dioxide results in a decrease in seawater pH, a process known as “ocean acidification”. The pearl oyster Pinctada fucata, the noble scallop Chlamys...
