Fertilization of Norway spruce forest with wood ash and nitrogen affected both tree growth and composition of chemical defence
Hanssen, Kjersti Holt; Asplund, Johan; Clarke, Nicholas; Selmer, Ruben; Nybakken, Line (Peer reviewed; Journal article, 2020-10-05)We fertilized a Norway spruce (Picea abies (L.) Karst.) stand on rich mineral soil with 3 t ha−1 of wood ash (ASH), 150 kg ha−1 of nitrogen (N) or a combination of wood ash and nitrogen (ASH + N), in addition to unfertilized ... -
Harvesting history affects soil respiration and litterfall but not overall carbon balance in boreal Norway spruce forests
Madsen, Rieke Lo; Asplund, Johan; Nybakken, Line; Kjønaas, O. Janne (Peer reviewed; Journal article, 2025-01-02)Understanding long-term effects of clear-cutting on current soil carbon (C) fluxes in boreal forests is important in the perspective of global C cycling and future forest management decisions. We studied twelve pairs of ... -
Long term effects of forest management on forest structure and dead wood in mature boreal forests
Asplund, Johan; Nordén, Jenni; Kjønaas, O. Janne; Madsen, Rieke Lo; Lunde, Lisa Fagerli; Birkemoe, Tone; Ronold, Eivind Kverme; Norkute, Milda; Jansson, Ulrika; Karlsen, Damian P.; Sverdrup-Thygeson, Anne; Skrede, Inger; Methlie, Ine-Susanne Hopland; Maurice, Sundy; Botten, Ulrik G.; Krok, Regine; Kauserud, Håvard; Nybakken, Line (Peer reviewed; Journal article, 2024-10-09)The history of forestry in Fennoscandia spans five centuries, with clear-cutting being the dominant practice since the mid-20th century. This has led to a significant transformation of the forest landscape. In this study ... -
Three decades of environmental change studies at alpine Finse, Norway: climate trends and responses across ecological scales
Roos, Ruben Erik; Asplund, Johan; Birkemoe, Tone; Halbritter Rechsteiner, Aud Helen; Olsen, Siri Lie; Vassvik, Linn; van Zuijlen, Kristel; Klanderud, Kari (Peer reviewed; Journal article, 2022-11-30)The International Tundra Experiment (ITEX) was established to understand how environmental change impacts Arctic and alpine ecosystems. The success of the ITEX-network has allowed for several important across-site syntheses, ...
