Seminar – 13 November – Modelling the nitrogen cycle of mosses across the boreal forest.

Rose Lefebvre will be presenting Modelling the nitrogen cycle of mosses across the boreal forest.

Date: 13 November 2024
Time: 13:00-14:00 Eastern Time
Location: Zoom (details are posted in our Teams site).

Mosses are common ground cover species in the boreal forest. They can influence different components of the ecosystem, such as the ground thermal regime due to their insulating properties, and the nitrogen cycle through biological nitrogen fixation. Mosses are not always included in terrestrial biosphere models, which are used to make climate projections. The Canadian Land Surface Scheme Including Biogeochemical Cycles (CLASSIC) was modified with the goal of improving productivity simulations across the North American boreal forest. Feather mosses and the nitrogen cycle of mosses were implemented in CLASSIC. The model was validated by comparing observation data against model output at eight sites. The sites range from being near the southern limit of permafrost to being in the continuous permafrost zone. Once validated, the model was run across the North American boreal forest.
