• Climate change drives substantial decline of understorey species richness and abundance in Norway spruce forests during 32 years of vegetation monitoring 

      Økland, Tonje; Halvorsen, Rune; Lange, Holger; Nordbakken, Jørn-Frode; Clarke, Nicholas (Peer reviewed; Journal article, 2023-05-31)
      Questions Observations in permanent forest vegetation plots in Norway and elsewhere indicate that complex changes have taken place over the period 1988–2020. These observations are summarised in the “climate-induced ...
    • Composite landscape predictors improve distribution models of ecosystem types 

      Simensen, Trond; Horvath, Peter; Vollering, Julien; Erikstad, Lars; Halvorsen, Rune; Bryn, Anders (Peer reviewed; Journal article, 2020-06-10)
      Aim: Distribution modelling is a useful approach to obtain knowledge about the spatial distribution of biodiversity, required for, for example, red-list assessments. While distribution modelling methods have been applied ...

      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 ...
    • What explains inconsistencies in field-based ecosystem mapping? 

      Naas, Adam Eindride; Halvorsen, Rune; Horvath, Peter; Wollan, Anders Kvalvåg; Bratli, Harald; Brynildsrud, Katrine Marie; Finne, Eirik Aasmo; Keetz, Lasse Torben; Lieungh, Eva; Olson, Christine; Simensen, Trond; Skarpaas, Olav; Tandstad, Hilde; Torma, Michal; Værland, Espen Sommer; Bryn, Anders (Peer reviewed; Journal article, 2023-02-11)
      Questions: Field-based ecosystem mapping is prone to observer bias, typically resulting in a mismatch between maps made by different mappers, that is, inconsistency. Experimental studies testing the influence of site, ...
