BIOTIC BIOdiversity & Biotic InTeractIons: Characterization, Dynamics and Functional Consequences. This axis has enhanced coloring on the role of biotic interactions and functional dimensions

BIOTIC : BIOdiversity & bioTIC interactions     





Integrate diversity and the role of biotic interactions in lake ecosystem functioning models




Functional diversity of benthic prokaryotes and role in the methane cycle (in relation to local and global pressures)?

- Characterization of the diversity and role of microbial parasites (viruses, bacteria, chytrids and protists) T

- Integration of microbial communities in trophic network models and influence on the fate of C in the pelagic zone.

Share of chemical ecology in biotic interactions: diversity of secondary metabolites produced by primary producers (under different forcings) and relationship to community structure and trophic functioning.

Invasive non-native species: impacts on the food web and ecological consequences

Study responses to multiple pressures & prioritize local and global forcing: multi-scale approaches



Impacts of changes in thermal stratification on pelagic communities (including cyanobacteria): multi-lake approaches

Dynamics of biodiversity (eukaryotes and cyanobacteria) under anthropogenic and climatic forcings during the anthropocene: reference states, turn-over and tipping points

Impacts of local and global pressures on coastal communities

Impacts of different local and global pressures (rearing, fishing, climate change, reduction of P content, invasive species) on the spatio-temporal dynamics of fish populations
