Giant plankton gains long-due attention

ScienceDaily: A team of marine biologists and oceanographers from CNRS, UPMC[1] and the German organization GEOMAR have revealed the importance in all the world's oceans of a group of large planktonic organisms called Rhizaria, which had previously been completely underestimated. According to their findings, these organisms make up 33% of the total abundance of large zooplankton in the world's oceans, and account for 5% of the overall marine biomass. The study was carried out on samples collected during eleven...

Increased carbon dioxide enhances plankton growth
2016-01-17 18:01:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Coccolithophores -- tiny calcifying plants that are part of the foundation of the marine food web -- have been increasing in relative abundance in the North Atlantic over the last 45 years, as carbon input into ocean waters has increased. Their relative abundance has increased 10 times, or by an order of magnitude, during this sampling period. This finding was diametrically opposed to what scientists had expected since coccolithophores make their plates out of calcium carbonate, which is becoming...

Don't forget plankton in climate change models, says study
2015-11-27 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A new study from the University of Exeter, published in the journal Ecology Letters, found that phytoplankton -- microscopic water-borne plants -- can rapidly evolve tolerance to elevated water temperatures. Globally, phytoplankton absorb as much carbon dioxide as tropical rainforests and so understanding the way they respond to a warming climate is crucial. Phytoplankton subjected to warmed water initially failed to thrive but it took only 45 days, or 100 generations, for them to evolve tolerance...

Rapid plankton growth in ocean seen sign carbon dioxide loading
2015-11-27 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of increased carbon dioxide in the ocean, a study led a by Johns Hopkins University scientist has found. What these findings mean remains to be seen, however, as does whether the rapid growth in the tiny plankton's population is good or bad news for the planet. Published Thursday in the journal Science, the study details a tenfold increase...
