Marine ammonia-oxidizing archaeal isolates display obligate mixotrophy and wide ecotypic variation

Ammonia-oxidizing archaea (AOA) are now implicated in exerting significant control over the form and availability of reactive nitrogen species in marine environments. Detailed studies of specific metabolic traits and physicochemical factors controlling their activities and distribution have not been well constrained in part due to the scarcity of isolated AOA strains. 244 more words


Effect of CO2, nutrients and light on coastal plankton. II. Metabolic rates

We conducted a microcosm experiment aimed at studying the interactive effects of high CO2, nutrient loading and irradiance on the metabolism of a planktonic community sampled in the Western Mediterranean near the coast of Málaga. 273 more words


Changes in microbial communities in coastal sediments along natural CO2 gradients at a volcanic vent in Papua New Guinea

Natural CO2 venting systems can mimic conditions that resemble intermediate to high pCO2 levels as predicted for our future oceans. They represent ideal sites to investigate potential long-term effects of ocean acidification on marine life. 205 more words


Organism-Specific Probe Selection and rRNA depletion

As detailed in a previous post, rRNA depletion with Ribo-zero greatly increases the number of usable reads in RNASeq studies, but this one-size-fits-all approach is not appropriate for some researchers. 168 more words
