Publications

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...

Publications

Expected limits on the ocean acidification buffering potential of a temperate seagrass meadow

International Atomic Energy Agency (IAEA) Publications

Ocean acidification threatens many marine organisms, especially marine calcifiers. The only global‐scale solution to ocean acidification remains rapid reduction in CO2 emissions....

Publications

Net loss of CaCO3 from a subtropical calcifying community due to seawater acidification: mesocosm-scale experimental evidence

International Atomic Energy Agency (IAEA) Publications

Acidification of seawater owing to oceanic uptake of atmospheric CO2 originating from human activities such as burning of fossil fuels and land-use changes has raised serious concerns...

Changes in water quality following opening and closure of a bar-built estuary (Pescadero, California)

International Atomic Energy Agency (IAEA) Publications

Bar-built estuaries are coastal environments characterized by the partial closure of the estuary's mouth with a sandbar barrier for extended periods (closed state). Through natural events...

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...

Indicators of climate change and social vulnerability in fishing dependent communities along the Eastern and Gulf Coasts of the United States

International Atomic Energy Agency (IAEA) Publications

Changing climatic conditions are affecting the relationship between fishing communities and the marine resources they depend on. This shift will require an adaptive response on the part...

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,...

Publications

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...

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...

Publications

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...

Changes in pteropod distributions and shell dissolution across a frontal system in the California Current System

International Atomic Energy Agency (IAEA) Publications

We tested the sensitivity of the vertical distributions and shell dissolution patterns of thecosome pteropods to spatial gradients associated with an eddy-associated front in the southern...

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...

Publications

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...
