Plant - Soil Ecology Lab

UQTR Chair in Arctic Functional Ecology


Are you particularly interested in the functional strategies that living organisms deployed to interplay with biogeochemical cycles of carbon, nitrogen and water (H2O) and coexist within community?

- What strategies are used by different species, and different individuals, for acquiring and using nutrients?

- How are these strategies modulated by environment such as climate, soil fertility and field management?

- How do competing strategies interact such that coexistence or dominance results, in a given community?

- How do these strategies at individual and community levels affect the emergent properties of the entire system (e.g. feedback on carbon, nitrogen and water cycles)?

Here, we use a variety of approaches, including the observation, experimentation and prediction of the functioning of plant and microbe species and communities to tackle these questions.

We explore these questions at the interface of ecophysiology and functional ecology by using the concepts of different disciplines (ecology, biology, chemistry and mathematics), conducting my experimentation from the field to the laboratory, and analyzing the data through statistical and simulation modeling.

Our actual playgrounds are in the canadian arctic tundra and the floodplain of the St-Lawrence River.

Our recent work is presented in the subsequent pages.
