COral Surface MICrolayer: production and dynamics of mucus-associated microbial communities (COSMIC)
Date du début: 1 août 2013, Date de fin: 31 juil. 2015,
Microbial biofilms that flourish within mucous sheets play decisive roles on the microspatial to the ecosystem scale. Coral surface mucus forms a dynamic boundary layer between the coral host epithelium and the surrounding seawater. Coral mucus sustains a diverse microbial assemblage and acts as a first barrier of defence against a wide range of environmental disturbances, thereby contributing to ...

ROle of crustacean zooplankton on prokaryotic community composition in the MEsopelagic Ocean (ROMEO)
Date du début: 3 avr. 2012, Date de fin: 2 avr. 2014,
"The ROMEO proposal aims at linking aspects of two scientific fields, traditionally separated, zooplankton ecology and microbial oceanography. ROMEO will investigate the influence of zooplankton activity on the prokaryotic community composition and activity in the open North Atlantic. During a four-week expedition in North Atlantic, the dominant crustacean zooplankton will be collected and the com ...

Crenarchaeota ecology and nutrient utilization in the subsurface ocean (CAENEUS) (CAENEUS)
Date du début: 1 juin 2010, Date de fin: 31 mai 2012,
"Over the past 10 years, it become apparent that Crenarchaeota are not only striving in some extreme environments but that they are ubiquitously present in the aquatic and terrestrial environment including the oceanic water column. In the pelagic realm of the ocean, their relative contribution to the total prokaryotic abundance increases with depth. It has been shown that the mesophilic Marine Cre ...

Heterotrophic activity and Ecology of abundant versus RAre marine bacterial phylotypes (HERA)
Date du début: 4 mai 2009, Date de fin: 3 mai 2011,
"The recent discovery of a large number of low abundance bacterial phylotypes, coined the ‘rare biosphere’, coexisting next to a few abundant phylotypes raises a number of fundamental questions concerning their role in the microbial food web and their functioning in the biogeochemical cycles, mainly driven by prokaryotes in the ocean. HERA addresses some of these basic questions concerning the rol ...

Archaeal activity dynamics in marine snow vs. ambient water in coastal European Sea (ARCADIA)
Date du début: 15 janv. 2009, Date de fin: 14 janv. 2011,
"Our knowledge on the marine nitrogen cycle has undergone some major revisions very recently with the discovery of novel pathways mediated by thus far unknown and partly unculturable prokaryotes. Among these new drivers of the nitrogen cycle are non-thermophilic Crenarchaea and Euryarchaea. Recently, Crenarchaea have been shown to harbor the amoA gene, responsible for the expression of ammonia mon ...
