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...

Publications

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

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...

Publications

Metabolic responses of the North Pacific krill, Euphausia pacifica, to short- and long-term pCO2 exposure

International Atomic Energy Agency (IAEA) Publications

While ocean acidification is likely to have major effects on many marine organisms, those species that regularly experience variable pCO2 environments may be more tolerant of future...

Publications

Respiratory response of the intertidal seastar Parvulastra exigua to contemporary and near-future pulses of warming and hypercapnia

International Atomic Energy Agency (IAEA) Publications

As typical of intertidal invertebrates the asterinid seastar Parvulastra exigua experiences marked variation in environmental temperature and pH/pCO2 due to tidal exchange and diurnal...

Publications

Effect of marine acidification on calcification and respiration of Chlamys farreri

International Atomic Energy Agency (IAEA) Publications

Marine acidification will be an important environmental problem in the near future as a result of persistent emissions of CO2 and dissolution into seawater. In this study, we found that...

Publications

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...

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...

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...

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

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...

Publications

Combined effects of short-term exposure to elevated CO2 and decreased O2 on the physiology and energy budget of the thick shell mussel Mytilus coruscus

International Atomic Energy Agency (IAEA) Publications

Hypoxia and ocean acidification are two consequences of anthropogenic activities. These global trends occur on top of natural variability. In environments such as estuarine areas, short-...

Publications

Variability in larval gut pH regulation defines sensitivity to ocean acidification in six species of the Ambulacraria superphylum

International Atomic Energy Agency (IAEA) Publications

The unusual rate and extent of environmental changes due to human activities may exceed the capacity of marine organisms to deal with this phenomenon. The identification of physiological...

Effects of elevated atmospheric CO2 on growth, photosynthesis and nitrogen metabolism in the economic brown seaweed, Hizikia fusiforme (Sargassaceae, Phaeophyta)

International Atomic Energy Agency (IAEA) Publications

Hizikia fusiforme (Harv.) Okamura (brown seaweed) was cultured using aeration with two CO2 conditions: outdoor air (actual atmospheric CO2 concentration, averaging 360 $μ$l l-1) and...

Ocean acidification increases the accumulation of toxic phenolic compounds across trophic levels

International Atomic Energy Agency (IAEA) Publications

Increasing atmospheric CO2 concentrations are causing ocean acidification (OA), altering carbonate chemistry with consequences for marine organisms. Here we show that OA increases by...

Photoperiod mediates the effects of elevated CO2 on the growth and physiological performance in the green tide alga Ulva prolifera

International Atomic Energy Agency (IAEA) Publications

Ulva spp., an increasingly important food, are the dominant species of the large-scale green tides. In this study, both the growth and the physiological responses of the Ulva prolifera...

Physiological response to elevated temperature and pCO2 varies across four Pacific coral species: Understanding the unique host+symbiont response

International Atomic Energy Agency (IAEA) Publications

The physiological response to individual and combined stressors of elevated temperature and pCO2 were measured over a 24-day period in four Pacific corals and their respective symbionts...
