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...

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...

Publications

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...

Publications

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....

Publications

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...

Publications

Acidification alters the composition of ammonia‑oxidizing microbial assemblages in marine mesocosms

International Atomic Energy Agency (IAEA) Publications

Increasing atmospheric CO2 concentrations are causing decreased pH over vast expanses of the ocean. This decreasing pH may alter biogeochemical cycling of carbon and nitrogen via the...

Publications

Size-dependent physiological responses of the branching coral Pocillopora verrucosa to elevated temperature and pCO2

International Atomic Energy Agency (IAEA) Publications

Body size has large effects on organism physiology, but these effects remain poorly understood in modular animals with complex morphologies. Using two trials of a ∼24 day experiment...

Saturating light and not increased carbon dioxide under ocean acidification drives photosynthesis and growth in (Chlorophyta)

International Atomic Energy Agency (IAEA) Publications

Carbon physiology of a genetically identified Ulva rigida was investigated under different CO2(aq) and light levels. The study was designed to answer whether (1) light or exogenous...

Publications

Dynamic patterns and ecological impacts of declining ocean pH in a high-resolution multi-year dataset

International Atomic Energy Agency (IAEA) Publications

Increasing global concentrations of atmospheric CO2 are predicted to decrease ocean pH, with potentially severe impacts on marine food webs, but empirical data documenting ocean pH over...
