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...

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...

Publications

Effects of elevated pCO2 on the survival, growth, and moulting of the Pacific krill species, Euphausia pacifica

International Atomic Energy Agency (IAEA) Publications

While ocean acidification (OA) is expected to have wide-ranging negative effects on marine species, organisms currently living in variable pH environments that expose them intermittently...

Publications

Persistence of positive carryover effects in the oyster, Saccostrea glomerata, following transgenerational exposure to ocean acidification

International Atomic Energy Agency (IAEA) Publications

Ocean acidification (OA) is predicted to have widespread implications for marine organisms, yet the capacity for species to acclimate or adapt over this century remains unknown. Recent...

Publications

Early benthic juvenile Parvulastra exigua (Asteroidea) are tolerant to extreme acidification and warming in its intertidal habitat

International Atomic Energy Agency (IAEA) Publications

Habitat warming and acidification experienced by intertidal invertebrates are potentially detrimental to sensitive early post-larvae of benthic marine invertebrates. To determine the...

Sponge bioerosion on changing reefs: ocean warming poses physiological constraints to the success of a photosymbiotic excavating sponge

International Atomic Energy Agency (IAEA) Publications

Excavating sponges are prominent bioeroders on coral reefs that in comparison to other benthic organisms may suffer less or may even benefit from warmer, more acidic and more eutrophic...

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...

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...

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...

Seawater acidification induced immune function changes of haemocytes in Mytilus edulis: a comparative study of CO2 and HCl enrichment

International Atomic Energy Agency (IAEA) Publications

The present study was performed to evaluate the effects of CO2- or HCl-induced seawater acidification (pH 7.7 or 7.1; control: pH 8.1) on haemocytes of Mytilus edulis, and the changes in...

Synergistic effects of elevated carbon dioxide and sodium hypochlorite on survival and impairment of three phytoplankton species

International Atomic Energy Agency (IAEA) Publications

Sodium hypochlorite (NaOCl) is widely used to disinfect seawater in power plant cooling systems in order to reduce biofouling, and in ballast water treatment systems to prevent transport...

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...
