B01c - The Biogeochemistry and Ecohydrology of pristine and disturbed peatlands
Date & Time
Tuesday, May 9, 2023, 10:00 AM - 11:30 AM

Peatlands cover more than 10% of Canada and store over 100 Gt C, making them one of Canada’s largest terrestrial carbon pools. Peatlands are currently experiencing climate and land-use change, altering their ecohydrology and biogeochemical cycling of carbon, nitrogen, phosphorus and other elements. Peatlands are ecosystems looked to for natural climate solutions, but assessing their capacity to contribute requires understanding the links among their hydrology, ecology and biogechemistry. This session seeks presentations of research on the ecohydrology and biogeochemistry of undisturbed and disturbed peatlands. Empirical and theoretical studies are welcome.
