Responses of neurogenesis and neuroplasticity related genes to elevated CO2 levels in the brain of three teleost species

International Atomic Energy Agency (IAEA) Publications

The continuous increase of anthropogenic CO2 in the atmosphere resulting in ocean acidification has been reported to affect brain function in some fishes. During adulthood, cell...

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...

Habitat preferences of coral-associated fishes are altered by short-term exposure to elevated CO2

International Atomic Energy Agency (IAEA) Publications

Rising atmospheric carbon dioxide (CO2) concentrations are causing additional CO2 to be absorbed by the oceans. Recent studies show that exposure to elevated CO2 causes olfactory...

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....

Ocean acidification affects prey detection by a predatory reef fish

International Atomic Energy Agency (IAEA) Publications

Changes in olfactory-mediated behaviour caused by elevated CO2 levels in the ocean could affect recruitment to reef fish populations because larval fish become more vulnerable to...

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-...

Effects of CO2 and seawater acidification on the early stages of Saccharina japonica development

International Atomic Energy Agency (IAEA) Publications

In this paper, we demonstrated that ocean acidification (OA) had significant negative effects on the microscopic development of Saccharina japonica in a short-term exposure experiment...

Elevated CO2 affects the behavior of an ecologically and economically important coral reef fish

International Atomic Energy Agency (IAEA) Publications

We tested the effect of near-future CO2 levels (≈490, 570, 700, and 960 $μ$atm CO2) on the olfactory responses and activity levels of juvenile coral trout, Plectropomus leopardus, a...

Abiotic and biotic interactions in the diffusive boundary layer of kelp blades create a potential refuge from ocean acidification

International Atomic Energy Agency (IAEA) Publications

1.Seaweeds are able to modify the chemical environment at their surface, in a micro‐zone called the diffusive boundary layer (DBL), via their metabolic processes controlled by light...

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...

Functional traits for carbon access in macrophytes

International Atomic Energy Agency (IAEA) Publications

Understanding functional trait distributions among organisms can inform impacts on and responses to environmental change. In marine systems, only 1% of dissolved inorganic carbon in...

Interactive effects of temperature, CO2 and nitrogen source on a coastal California diatom assemblage

International Atomic Energy Agency (IAEA) Publications

Diatoms are often considered to be a single functional group, yet there is a great deal of morphological, genetic and ecological diversity within the class. How these differences will...

Ocean acidification increases the vulnerability of native oysters to predation by invasive snails

International Atomic Energy Agency (IAEA) Publications

There is growing concern that global environmental change might exacerbate the ecological impacts of invasive species by increasing their per capita effects on native species. However,...

Impaired learning of predators and lower prey survival under elevated CO2: a consequence of neurotransmitter interference

International Atomic Energy Agency (IAEA) Publications

Ocean acidification is one of the most pressing environmental concerns of our time, and not surprisingly, we have seen a recent explosion of research into the physiological impacts and...

CO2-driven seawater acidification increases photochemical stress in a green alga

International Atomic Energy Agency (IAEA) Publications

Increased CO2 and associated acidification in seawater, known as ocean acidification, decreases calcification of most marine calcifying organisms. However, there is little information...

Publications

Elevated seawater CO2 concentrations impair larval development and reduce larval survival in endangered northern abalone (Haliotis kamtschatkana)

International Atomic Energy Agency (IAEA) Publications

Increasing levels of anthropogenic carbon dioxide in the world's oceans are resulting in a decrease in the availability of carbonate ions and a drop in seawater pH. This process, known as...

The effect of pH on natural settlement and metamorphosis in the invasive limpet, Crepidula fornicata

International Atomic Energy Agency (IAEA) Publications

The average pH of ocean surface waters has dropped by about 30%, due to absorption of anthropogenic CO2 emissions. In the past decade, much research has been conducted examining the...
