Peatlands are wetland ecosystems characterized by an accumulation of organic matter that
exceeds decomposition (Charman, 2002). Over time, the accumulation of organic layers …

The subarctic fens of the Laforge region possess a microtopography of large pools and
narrow strings, implying an imbalance between hydrology and peat accumulation. In this …

Northern peatlands, wetland ecosystems occurring in the boreal and arctic zones of our
planet, store large amounts of carbon, corresponding to 34–46% currently stored in the …

Peatlands cover 12 to 17% of the Canadian territory (Letts et al., 2000; Tarnocai et al., 2000;
Payette et Rochefort, 2001; Lafleur et al., 2005) and approximately 9 to 12% of the Quebec …

Peatlands are natural ecosystems that provide archives of the hydrological cycle, ecological
processes and terrestrial carbon dynamics. In the north-central region of Quebec (eastern …

Peatlands and associated ecosystem services are sensitive to climate changes and
anthropogenic pressures such as drainage. This study illustrates these effects on the …

Ombrotrophic bogs can comprise a mosaic of vegetation patches and open-water pools,
with hydrological and biogeochemical connections between pools and the surrounding peat …

In the framework of climate changes, peatland ecosystems are compartments of the Critical
Zone of growing importance for greenhouse gas (GHG) exchanges with the atmosphere …

Mitigating and adapting to global changes requires a better understanding of the response
of the Biosphere to these environmental variations. Human disturbances and their effects act …

Peatlands accumulate and store dead organic matter from wetland vegetation under
permanent water saturated conditions and low oxygen content, making it an important …
