Effects of pCO2 on spatial competition between the corals Montipora aequituberculata and Porites lutea

International Atomic Energy Agency (IAEA) Publications

We tested the hypothesis that ocean acidification (OA) affects spatial competition among scleractinian corals. Competitive ability was evaluated indirectly by linear extension of Porites...

Upwelling modulation of functional traits of a dominant planktonic grazer during “warm-acid” El Niño 2015 in a year-round upwelling area of Humboldt Current

International Atomic Energy Agency (IAEA) Publications

Climate change is expected to exacerbate upwelling intensity and natural acidification in Eastern Boundaries Upwelling Systems (EBUS). Conducted between January-September 2015 in a...

A “core-top” screen for trace element proxies of environmental conditions and growth rates in the calcite skeletons of bamboo corals (Isididae)

International Atomic Energy Agency (IAEA) Publications

We test for trace element proxies in the high-magnesium calcite fraction of bamboo coral internodes by comparing environmental conditions and growth rates to the specimen-mean...

Insights from sodium into the impacts of elevated pCO2 and temperature on bivalve shell formation

International Atomic Energy Agency (IAEA) Publications

Ocean acidification and warming are predicted to affect the ability of marine bivalves to build their shells, but little is known about the underlying mechanisms. Shell formation is an...

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

Emiliania huxleyi shows identical responses to elevated pCO2 in TA and DIC manipulations

International Atomic Energy Agency (IAEA) Publications

With respect to their sensitivity to ocean acidification, calcifiers such as the coccolithophore Emiliania huxleyi have received special attention, as the process of calcification seems...

Coral calcification from skeletal records revisited

International Atomic Energy Agency (IAEA) Publications

Skeletal growth records in annually banded massive coral skeletons are an under-exploited archive of coral responses to environmental changes. Average linear extension and calcification...

Publications

Diffusion boundary layers ameliorate the negative effects of ocean acidification on the temperate coralline macroalga Arthrocardia corymbosa

International Atomic Energy Agency (IAEA) Publications

Anthropogenically-modulated reductions in pH, termed ocean acidification, could pose a major threat to the physiological performance, stocks, and biodiversity of calcifiers and may...

Publications

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...

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...

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...

Publications

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...

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...

Toxic dinoflagellate blooms of in Chilean fjords: a resilient winner from climate change

International Atomic Energy Agency (IAEA) Publications

Exposure of the toxigenic dinoflagellate Alexandrium catenella to variations in pCO2/pH, comparable to current and near-future levels observed in Southern Chilean fjords, revealed...

Near-future ocean acidification enhances the feeding rate and development of the herbivorous juveniles of the crown-of-thorns starfish, Acanthaster planci

International Atomic Energy Agency (IAEA) Publications

Population outbreaks of the corallivorous crown-of-thorns starfish, Acanthaster planci, are a major contributor to the decline in coral reef across the Indo-Pacific. The success of A....

Differential responses of growth and photosynthesis in the marine diatom Chaetoceros muelleri to CO2 and light availability

International Atomic Energy Agency (IAEA) Publications

This study investigated the impact of photon flux and elevated CO2 concentrations on growth and photosynthetic electron transport on the marine diatom Chaetoceros muelleri and looked for...

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...

Elevated CO2 does not exacerbate nutritional stress in larvae of a Pacific flatfish

International Atomic Energy Agency (IAEA) Publications

Multiple aspects of climate change are expected to co-occur such that ocean acidification will take place in conjunction with warming and a range of trophic changes. Previous studies have...

Coral calcifying fluid pH dictates response to ocean acidification

International Atomic Energy Agency (IAEA) Publications

Ocean acidification driven by rising levels of CO2 impairs calcification, threatening coral reef growth. Predicting how corals respond to CO2 requires a better understanding of how...
