Plasticity predicts evolution in a marine alga

Under global change, populations have four possible responses: ‘migrate, acclimate, adapt or die’ (Gienapp et al. 2008 Climate change and evolution: disentangling environmental and genetic response. 242 more words

Effect of ocean warming and acidification on a plankton community in the NW Mediterranean Sea

The effect of ocean warming and acidification was investigated on a natural plankton assemblage from an oligotrophic area, the bay of Villefranche (NW Mediterranean Sea). The assemblage was sampled in March 2012 and exposed to the following four treatments for 12 days: control (∼360 μatm, 14°C), elevated pCO2 (∼610 μatm, 14°C), elevated temperature (∼410 μatm, 17°C), and elevated pCO2 and temperature (∼690 μatm, 17°C). 237 more words

Consistent increase in dimethyl sulfide (DMS) in response to high CO2 in five shipboard bioassays from contrasting NW European waters (update)

The ubiquitous marine trace gas dimethyl sulfide (DMS) comprises the greatest natural source of sulfur to the atmosphere and is a key player in atmospheric chemistry and climate. 265 more words

Effects of different pCO2 concentrations on marine bacterial community structure, Eastern Harbor, Alexandria, Egypt

The direct effect of an elevated CO2 concentration range (280, 385, 550, 750 and 1050 μatm) on the marine bacterial counts and dominancy of species were examined. 259 more words

Late winter under ice pelagic microbial communities in the high Arctic Ocean and the impact of short-term exposure to elevated CO2 levels

Polar Oceans are natural CO2 sinks because of the enhanced solubility of CO2 in cold water. The Arctic Ocean is at additional risk of accelerated ocean acidification (OA) because of freshwater inputs from sea ice and rivers, which influence the carbonate system. 242 more words

Prokaryotes

Today it is widely known that one of the smallest and most abundant living organisms on earth go by the name, “prokaryotes.” These microorganisms have been the center of much scientific investigation. 1,165 more words
