Species-specific photosynthetic responses of symbiotic zoanthids to thermal stress and ocean acidification

Increasing sea-surface temperatures and ocean acidification (OA) are impacting physiologic processes in a variety of marine organisms. Many sea anemones, corals and jellies in the phylum Cnidaria form endosymbiotic relationships with Symbiodinium spp. 304 more words


Cnidaria, cnidarian

Look at that pretty thing. It has a rounded cap on it followed by a mess of attachments trailing off, pointing in various directions.

Frozen here but fluid in reality, never quite the same from one instant to the next, and, as you see it, in an engagingly backlit form, though with the contrast a bit stinging. 558 more words

The impact of CO2 emissions on 'nuisance' marine species (video & text)

Anthropogenic CO2 emissions are being taken up from the atmosphere by the oceans, increasing the availability of dissolved inorganic carbon but reducing both the carbonate saturation and pH of seawater. 291 more words


Carbonic anhydrase activity changes in response to increased temperature and pCO2 in Symbiodinium–zoanthid associations

Carbon dioxide (CO2) makes up less than 1% of dissolved inorganic carbon (DIC) in the ocean. To acquire carbon dioxide for photosynthesis, many marine autotrophs rely on the enzyme carbonic anhydrase (CA) to catalyze the conversion of bicarbonate ions (HCO3−) to CO2. 236 more words
