What do baseball and fishes have in common?

Here’s the third in our series of guest posts from California Academy of Sciences ichthyologist Dr. Luiz Rocha I am not going to lie to you, before moving to San Francisco I barely knew the rules of baseball. But during the mere three years that I have lived here, our local team (the Giants in […]

The strait of Georgia is turning to acid, new research shows

“Some people call it the elephant in the room. I like to call it the blue whale in the pool,” scientist Brian Kingzett told a room of naturalists this week. He was talking about the dramatic rise in ocean acidity along the B.C. coast. As the Oceanside Star reports, Kingzett, field station manager for the […]

Acid Arctic Ocean and Russell Brand? (text & audio)

Is ocean acidification a term you are familiar with? If you are a regular Ice Blog reader, I would like to think you will be. But I am prompted to ask this question because the term came up during a discussion at a weekly evening class I attend, and I was flabbergasted that none of […]

Interaction of CO2 and light availability on photophysiology of tropical coccollitophorids

Three tropical coccolithophorids (Emiliania huxleyi, Gephyrocapsa oceanica and Ochosphaera sp) were grown at batch culture with CO2 system at two levels of CO2 (385 and 1000 ppm) and two different light dark periods. The aims of this study were 1) To determine calcification rate of three selected calcifying miroalgae (Emiliania huxleyi, Gepherocapsa oceanica and Ochospaera […]

Pathogenic challenge reveals immune trade-off in mussels exposed to reduced seawater pH and increased temperature

Ocean acidification (OA) and warming pose a considerable threat to marine ecosystems. Previous studies show that these environmental co-stressors significantly impact upon a number of key physiological functions, including calcification, metabolism and growth, in many marine organisms.

Is warmer better? Decreased oxidative damage in notothenioid fish after long-term acclimation to multiple stressors

Antarctic fish of the suborder Notothenioidei have evolved several unique adaptations to deal with subzero temperatures. However, these adaptations may come with physiological trade-offs, such as an increased susceptibility to oxidative damage. Show More Summary

These are a few of my favorite species: The Torpedo Ray

“Shields up! Phasers set to kill! Engage!” If the Pacific Torpedo Ray (Torpedo californica) had an inner dialogue whilst stalking delicious fishy snacks, I could imagine it would be something along these lines. In his literary masterpiece, Certainly More Than You Want to Know About the Fishes of the Pacific Coast,  Milton Love so rightly describes them as […]

Uncovering Shrimp Seafood Fraud: Diaries from the Field, Part One

(Photo: Rachel Golden) Yesterday, Oceana released a new report that uncovered widespread misrepresentation of America’s favorite seafood: shrimp. The report found 30 percent of DNA-tested shrimp samples to be misrepresented—often mislabeled for another species or said to be wild caught when it was farmed—across more than 100 restaurants and grocery stores nationwide. read more

Physiological response of Crocosphaera watsonii to enhanced and fluctuating carbon dioxide conditions

We investigated the effects of elevated pCO2 on cultures of the unicellular N2-fixing cyanobacterium Crocosphaera watsonii WH8501. Using CO2-enriched air, cultures grown in batch mode under high light intensity were exposed to initial...Show More Summary

Skeletal mineralogy of geniculate corallines: providing context for climate change and ocean acidification research

Marine species depositing high-magnesium (Mg) calcite (>8% MgCO3) are projected to be among the first to show response to the impacts of climate change, i.e. increased sea surface temperature (SST) and ocean acidification (OA), given the increasing solubility of calcite in seawater with increasing Mg content. Temperature is a major driver of Mg incorporation into […]
