Heterotrophic freshwater bacteria play an important role in converting organic carbon into atmospheric CO 2. This process may be affected by the environment but also by specific interactions between community members.
Here we show that microcosm assemblages with contrasting composition and functional properties can arise at identical growth condit...
Segregation and mixing shape the structure and functioning of aquatic microbial communities, but their respective roles are challenging to disentangle in field studies. We explored the hypothesis that functional differences and beta diversity among stochastically assembled communities would increase in the absence of dispersal. Contrariwise, we exp...
The freshwater microbiome harbours numerous copiotrophic bacteria that rapidly respond to elevated substrate concentrations. We hypothesized that their high centimetre‐scale beta diversity in lake water translates into pronounced metabolic variability, and that a large fraction of microbial ‘metabolic potential’ originates from point sources such a...
Bacterial community composition among individual, experimentally generated 'lake snow' particles may be highly variable. Since such aggregates are seasonally abundant in the mixed upper layer of lakes, we hypothesized that particle-attached (PA) bacteria disproportionally contribute to the small-scale spatial beta diversity of pelagic communities....
Stochasticity is a major cause of compositional β‐diversity in communities that develop under similar environmental conditions. Such communities may exhibit functional similarity due to sympatric taxa with equivalent metabolic capacities in the source assemblage. However, the redundancy of individual physiological traits may differ in the original...
Planktonic ciliate species form multiple trophic guilds and are central components of freshwater food webs. Progress in molecular analytical tools has opened new insight into ciliate assemblages. However, high and variable 18S rDNA copy numbers, typical for ciliates, make reliable quantification by amplicon sequencing extremely difficult. For an ex...
Freshwater microbial communities play a prominent role in the maintenance of Earth’s biogeochemical cycles. They also provide ecosystem services such as drinking water production and waste water treatment. The assembly of microbial communities is governed by deterministic and stochastic processes. Hence, similar environments rarely hold similar com...
Shallow thermokarst ponds are a conspicuous landscape element of the Arctic Siberian tundra with high biogeochemical variability. Little is known about how microbes from the regional species pool assemble into local pond communities, and how the resulting patterns affect functional properties such as dissolved organic carbon (DOC) remineralization...
The project aims to study the microbial diversity in arctic siberian thaw ponds and to link it to community functioning, especially in terms of greenhouse gas emissions.
This poster deals with experimental and observational work conducted to assess the question of the importance of stochasticity in bacterial community assembly.
Soil microorganisms are key players in soil functioning. Indeed these organisms are responsible for the decomposition of Soil Organic Matters (SOM) and deliver nutrients readily accessible to plants. While the biodegradation of SOM releases CO2 and CH4 to the atmosphere, it has been recently shown that microbial SOM biodegradation generates Volatil...
