Postdoctoral Associate

Rosalie's research initially focused on how ecosystems are responding to climatic perturbations. Before coming to UVM, she worked on lowland and high-altitude European lakes, at different temporal scales (millennial to sub-hourly resolution), on different responses (physical, chemical, biological). She questioned during her PhD whether lake ecology is more affected by climate change depending on their exposure (the warmer they get, the stronger shall be the climate-driven ecological changes) or depending on how they have been already locally affected by human activities (lakes already under strong local human pressure will be more sensitive to ecological effects of climate warming).

For her postdoctoral research at UVM, Rosalie is modelling the food web(s) of Lake Champlain, with the objective of quantifying how changes in food web structure affect the system functioning. Specific questions include spatial and temporal aspects: (1) Does the heterogeneity of Lake Champlain promote various equilibria? (2) Does the spatiality reflect several thresholds in environmental parameters? (3) What changes in environmental conditions allowed the natural recruitment of lake trout to start in the 2010s after decades of no recruits? (4) How might possible changes in fish stocking policies  impact the Lake Champlain food web?
