    • Akkumulering av nitrogen- variasjoner avhengig av bestandsutvikling, nitrogentilførsel og simulert snødekke 

      Sogn, Trine A.; Kjønaas, O. Janne; Stuanes, Arne. O.; Abrahamsen, Gunnar (Research report, 1997-11-01)
      Kunnskap om hvor mye N som kan akkumuleres i jordsmonnet er av stor betydning for beregning av tålegrenser for N i skogøkosystemet. Formålet med denne undersøkelsen var å fremskaffe bedre estimater for netto N-immobilise ...

    • Long term effects of clearcutting on litterfall and understory vegetation in boreal spruce forests in Norway 

      Biong, Rebecca (Master thesis, 2022)
      Boreal forests capture and store substantial amounts of carbon in a global perspective, and the soil is especially important acting like a long-term reservoir of captured atmospheric CO2. Most of the soil carbon originates ...

    • 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)
      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 ...

    • Shift in tree species changes the belowground biota of boreal forests 

      Mundra, Sunil; Kauserud, Håvard; Økland, Tonje; Nordbakken, Jørn-Frode; Ransedokken, Yngvild Eidissen; Kjønaas, O. Janne (Journal article; Peer reviewed, 2022)
      The replacement of native birch with Norway spruce has been initiated in Norway to increase long-term carbon storage in forests. However, there is limited knowledge on the impacts that aboveground changes will have on the ...

    • Shift in tree species changes the belowground biota of boreal forests 

      Mundra, Sunil; Kauserud, Håvard; Økland, Tonje; Nordbakken, Jørn-Frode; Ransedokken, Yngvild Eidissen; Kjønaas, O. Janne (Peer reviewed; Journal article, 2022)
      The replacement of native birch with Norway spruce has been initiated in Norway to increase long-term carbon storage in forests. However, there is limited knowledge on the impacts that aboveground changes will have on the ...

    • Soil depth matters: shift in composition and inter-kingdom co-occurrence patterns of microorganisms in forest soils 

      Mundra, Sunil; Kjønaas, O. Janne; Morgado, Luis; Krabberød, Anders Kristian; Ransedokken, Yngvild; Kauserud, Håvard (Peer reviewed; Journal article, 2021)
      Soil depth represents a strong physiochemical gradient that greatly affects soil-dwelling microorganisms. Fungal communities are typically structured by soil depth, but how other microorganisms are structured is less known. ...

    • Tree species effects on litter decomposition and soil carbon 

      Ransedokken, Yngvild (PhD thesis;2022:18, Doctoral thesis, 2022)
      Boreal forests soils play an important role in mitigating climate change as they are the largest terrestrial carbon pool. The accumulation of soil carbon is regulated by the balance of carbon and nitrogen input from plant ...
