Plant communities change above- and belowground based on mycorrhizal associations in subarctic tundra

Almeida, Juliana Diva portal (Dalarna University Library) 2026

Other claims from this paper (6)

Association A 50% aboveground biomass reduction corresponded to a 25% belowground biomass loss.
Intervention effect ERM belowground traits resisted random biomass removal.
Intervention effect Specific ERM plant removal increased root biomass and length of ECM species.
Observation Single-species SLA remained stable across treatments.
Association Empetrum nigrum showed a non-linear response to neighbour release and removal gradients.
Intervention effect Graminoid relative abundance declined after biomass and ECM removal.
