Symbiomics: Molecular Ecology and Evolution of Bacterial Symbionts (Symbiomics)
Date du début: 1 janv. 2011, Date de fin: 31 déc. 2014,
Symbiosis research is currently in the midst of a revolution as molecular techniques are leading to major breakthroughs in our understanding of interactions between animals and microbes. There is an emerging recognition that all animals are intimately associated with a complex community of beneficial microbes that are essential for their development, nutrition, and health. Thus, modern symbiosis r ...

Linking substrate consumption to consumer identity in carbon-cycling microbes inhabiting anoxic marine sediments (Substrate use)
Date du début: 1 janv. 2011, Date de fin: 31 déc. 2012,
Much of the organic matter produced on land and in aquatic systems is eventually deposited at the seafloor, making marine sediments the largest organic carbon sink on Earth. Predominantly, this organic matter is either remineralized to CO2 via biological activity or preserved over geologic time scales. A substantial fraction of remineralization is carried out by microbes that live below the sedime ...

The evolutionary consequences of inbreeding in natural populations: Genotypic-phenotypic interactions and implications for genetic diversity and evolutionary potential (ecogenomics)
Date du début: 1 avr. 2009, Date de fin: 31 mars 2012,
Studies of processes that maintain genetic variation for fitness are fundamental for understanding evolutionary forces shaping the life histories and phenotypic characteristics of animals. Such processes include evolutionary interactions between population genetic structure and mating system, dispersal patterns and social organization. The interplay between genetic diversity and adaptive evolution ...

The New Players in the Marine Nitrogen Cycle: Benthic Foraminifera (NITROFORAM)
Date du début: 1 juin 2008, Date de fin: 31 août 2011,
"Generally, anaerobic respiration of nitrate is regarded as a bacterial process. In addition to bacteria only three eukaryotes were known to have the potential to reduce nitrate and nitrous oxide. However, very recently three species of benthic foraminifera were found to respire nitrate completely to dinitrogen gas. To be able to do so they store high concentrations of nitrate in their cell (Risga ...
