      Laksforsmo Vindstad, Ole Petter; Jepsen, Jane Uhd; Ims, Rolf Anker (Journal article; Peer reviewed, 2015)
      Outbreaks by geometrid moths periodically cause mass mortality of trees and state changes in understorey vegetation in sub-arctic mountain birch forest in northern Scandinavia. In order to assess the short-term impacts of ...
