Bio/Research

My research activities are aimed, first, to define the ecological niches of bryophytes that inhabit bogs of western Canada on three gradients: the climate, the height of the water table and water chemistry. Niches where bryophytes are defined, the results will be used to reconstruct the climate and ecological conditions that existed in peatlands during the Holocene (between 10,000 and 3,000 years before the modern era) from bryophyte communities found in carrots in peat. Analysis of niches will also predict the effects of global warming on the distribution of bryophytes and peatlands in western Canada. It is also possible to determine the impact of climate change on the height of the water table and the water chemistry of peat. A second area of ??research involves the study of the impact of disturbances such as heavy metals from industrial or dirt roads on the flora of peatlands.
