    • Decadal decline in forest floor soil organic carbon after clear-cutting in Nordic and Canadian forests 

      Johannesson, Carl-Fredrik; Ilvesniemi, H.; Kjønaas, O. Janne; Larsen, K.S.; Lehtonen, A.; Nordén, Jenni; Paré, D.; Silvennoinen, Hanna Marika; Stendahl, J.; Stupak, I.; Vesterdal, L.; Dalsgaard, Lise (Peer reviewed; Journal article, 2025-04-03)
      Nordic and Canadian forests store substantial amounts of carbon (C) and are largely managed in a silvicultural system with clear-cut harvest. Previous meta-analyses of harvesting effects on soil C have shown short- to ...

    • Effekter på karbondynamikk, miljø og næring ved økt bruk av lukkede hogstformer 

      Granhus, Aksel; Antón-Fernández, Clara; de Wit, Heleen; Hanssen, Kjersti Holt; Schei, Fride Høistad; Jacobsen, Rannveig Margrete; Jansson, Ulrika; Korpunen, Heikki; Mohr, Christian Wilhelm; Nordén, Jenni; Rolstad, Jørund; Sevillano, Ignacio; Solberg, Svein; Storaunet, Ken Olaf; Vergarechea, Marta (NIBIO Rapport, Research report, 2024)
      Miljødirektoratet har gitt NIBIO, NINA og NIVA i oppdrag å vurdere hvilken effekt økt bruk av lukkede hogstformer kan ha for karbonlagring i skog, biodiversitet, økologisk tilstand, vannkvalitet og skognæring. Oppdraget ...

      Krah, Franz-Sebastian; Büntgen, Ulf; Schaefer, Hanno; Müller, Jörg; Andrew, Carrie; Boddy, Lynne; Diez, Jeffrey; Egli, Simon; Freckleton, Robert; Gange, Alan C.; Halvorsen, Rune; Heegaard, Einar; Heideroth, Antje; Heibl, Christoph; Heilmann-Clausen, Jacob; Høiland, Klaus; Kar, Ritwika; Kauserud, Håvard; Kirk, Paul M.; Kuyper, Thomas W.; Krisai-Greilhuber, Irmgard; Nordén, Jenni; Papastefanou, Phillip; Senn-Irlet, Beatrice; Bässler, Claus (Peer reviewed; Journal article, 2019-10-10)
      Thermal melanism theory states that dark-colored ectotherm organisms are at an advantage at low temperature due to increased warming. This theory is generally supported for ectotherm animals, however, the function of colors ...

    • 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 ...

      Johannesson, Carl-Fredrik; Nordén, Jenni; Lange, Holger; Silvennoinen, Hanna Marika; Larsen, Klaus Steenberg (Peer reviewed; Journal article, 2024-10-30)
      Non-steady-state chambers are often used for greenhouse gas flux measurements, and while there are recommendations on how long to keep the chamber closed, it is less investigated to what extent the length of the chamber ...
