The role of mycorrhizal type and plant dominance in regulating nitrogen cycling in Oroarctic soils
Abstract. Mycorrhizal fungi enhance plant access to nitrogen (N) in nutrient-poor environments like the Arctic tundra by depolymerizing N-rich organic compounds into forms available to plants and micr...

Since the start of 2025, most of the review requests I get have a two-week deadline. The pushy request and the "kind invitation to resubmit" follow a race to minimal record time for the editor's decision.
