Estimating lichen biomass in forests and peatlands of northwestern Canada in a changing climate
Climate warming in the North could lead to lichen decline within critical woodland caribou habitat. We used repeat measurements of sixty-nine plots over ten years (2007–2008 and 2017–2018) to assess lichen biomass changes under a warming climate along a latitudinal/climatic gradient in northwestern...

Climate warming in the North could lead to lichen decline within critical woodland caribou habitat.
