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...

Publications

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...

An ocean acidification acclimatised green tide alga is robust to changes of seawater carbon chemistry but vulnerable to light stress

International Atomic Energy Agency (IAEA) Publications

Ulva is the dominant genus in the green tide events and is considered to have efficient CO2 concentrating mechanisms (CCMs). However, little is understood regarding the impacts of ocean...

Technical Note: Maximising accuracy and minimising cost of a potentiometrically regulated ocean acidification simulation system

International Atomic Energy Agency (IAEA) Publications

This article describes a potentiometric ocean acidification simulation system which automatically regulates pH through the injection of 100% CO2 gas into temperature-controlled seawater....

Behavior of brooded coral larvae in response to elevated pCO2

International Atomic Energy Agency (IAEA) Publications

Elevated pCO2 threatens coral reefs through impaired calcification. However, the extent to which elevated pCO2 affects the distribution of the pelagic larvae of scleractinian corals, and...

Ocean acidification in the California Current System

International Atomic Energy Agency (IAEA) Publications

Eastern boundary upwelling systems (EBUS) are naturally more acidic than most of the rest of the surface ocean. Observations of EBUS already show pH values and saturation states with...

Bioeconomic analysis of the impact of ocean acidification associated with low recruitment of Isostichopus badionotus and implications for adaptive fishery management in the north of the Yucatan Peninsula, Mexico

International Atomic Energy Agency (IAEA) Publications

The impact that ocean acidification (OA) could generate in the fisheries of Isostichopus badionotus at the north of the Yucatan Peninsulta, Mexico, was analysed by reducing the value of a...

Interactive network configuration maintains bacterioplankton community structure under elevated CO2 in a eutrophic coastal mesocosm experiment

International Atomic Energy Agency (IAEA) Publications

There is increasing concern about the effects of ocean acidification on marine biogeochemical and ecological processes and the organisms that drive them, including marine bacteria. Here,...

Impact of seawater carbonate variables on post-larval bivalve calcification

International Atomic Energy Agency (IAEA) Publications

Several studies have demonstrated that shellfish calcification rate has been impacted by ocean acidification. However, the carbonate system variables responsible for regulating...

Publications

Shift from coral to macroalgae dominance on a volcanically acidified reef

International Atomic Energy Agency (IAEA) Publications

Rising anthropogenic CO2 in the atmosphere is accompanied by an increase in oceanic CO2 and a concomitant decline in seawater pH (ref. 1). This phenomenon, known as ocean acidification...

Assessment of ocean acidification and warming on the growth, calcification, and biophotonics of a California grass shrimp

International Atomic Energy Agency (IAEA) Publications

Cryptic colouration in crustaceans, important for both camouflage and visual communication, is achieved through physiological and morphological mechanisms that are sensitive to changes in...

Publications

Whole transcriptome analysis of the coral Acropora millepora reveals complex responses to CO2-driven acidification during the initiation of calcification

International Atomic Energy Agency (IAEA) Publications

The impact of ocean acidification (OA) on coral calcification, a subject of intense current interest, is poorly understood in part because of the presence of symbionts in adult corals....

Benthic buffers and boosters of ocean acidification on coral reefs

International Atomic Energy Agency (IAEA) Publications

Ocean acidification is a threat to marine ecosystems globally. In shallow-water systems, however, ocean acidification can be masked by benthic carbon fluxes, depending on community...

Seasonal patterns in aragonite saturation state on the southern California continental shelf

International Atomic Energy Agency (IAEA) Publications

Shoaling of the saturation horizon for aragonite in the California Current System has been well-documented; however, these reports are based primarily on surveys conducted in waters off...

Effects of climate change on Canada's Pacific marine ecosystems: a summary of scientific knowledge

International Atomic Energy Agency (IAEA) Publications

The marine life of Canada's Pacific marine ecosystems, adjacent to the province of British Columbia, may be relatively responsive to rapid oceanographic and environmental change...
