      1. Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in ...

    • 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 ...

    • Coprophagy in moose: A first observation 

      Spitzer, Robert; Åström, Cecilia; Felton, Annika M.; Eriksson, Monica; Meisingset, Erling L.; Solberg, Erling Johan; Rolandsen, Christer Moe (Peer reviewed; Journal article, 2023-01-06)
      Coprophagy, the eating of feces, has been documented in a wide range of species but appears to be rare or difficult to detect in deer (Cervidae). Here, we report the first observation of coprophagy in moose Alces alces, ...

    • Genetic substructure and admixture as important factors in linkage disequilibrium-based estimation of effective number of breeders in recovering wildlife populations 

      Kopatz, Alexander; Eiken, Hans Geir; Schregel, Julia; Aspi, Jouni; Kojola, Ilpo; Hagen, Snorre (Journal article; Peer reviewed, 2017)
      The number of effective breeders (Nb) and effective population size (Ne) are population parameters reflective of evolutionary potential, susceptibility to stochasticity, and viability. We have estimated these parameters ...

    • Inter-individual variability in spring phenology of temperate deciduous trees depends on species, tree size and previous year autumn phenology 

      Marchand, Lorène Julia; Dox, Inge; Gričar, Jožica; Prislan, Peter; Leys, Sebastien; Van den Bulcke, Jan; Fonti, Patrick; Lange, Holger; Matthysen, Erik; Peñuelas, Josep; Zuccarini, Paolo; Campioli, Matteo (Peer reviewed; Journal article, 2020-05-29)
      We explored the inter-individual variability in bud-burst and its potential drivers, in homogeneous mature stands of temperate deciduous trees. Phenological observations of leaves and wood formation were performed weekly ...

    • Neutral processes related to regional bee commonness and dispersal distances are important predictors of plant–pollinator networks along gradients of climate and landscape conditions 

      Sydenham, Markus A. K.; Venter, Zander; Moe, Stein Ragnar; Eldegard, Katrine; Kuhlmann, M.; Reitan, Trond; Rasmussen, C.; Paxton, R.; Dupont, Yoko L.; Skrindo, Astrid Brekke; Hegland, Stein Joar; Nielsen, Anders; Olesen, J.M.; Nowell, Megan Sara; Rusch, Graciela (Peer reviewed; Journal article, 2022-10-17)
      Understanding how niche-based and neutral processes contribute to the spatial varia-tion in plant–pollinator interactions is central to designing effective pollination con-servation schemes. Such schemes are needed to ...

    • Setting reference levels and limits for good ecological condition in terrestrial ecosystems – Insights from a case study based on the IBECA approach 

      Jakobsson, Simon; Töpper, Joachim Paul; Evju, Marianne; Framstad, Erik; Lyngstad, Anders; Pedersen, Bård; Sickel, Hanne; Sverdrup-Thygeson, Anne; Vandvik, Vigdis; Velle, Liv Guri; Aarrestad, Per Arild; Nybø, Signe (Peer reviewed; Journal article, 2020-05-16)
      Effective evidence-based nature conservation and habitat management relies on developing and refining our methodological toolbox for detecting critical ecological changes at an early stage. This requires not only optimizing ...

    • Snowmelt progression drives habitat selection and vegetation disturbance by an Arctic avian herbivore 

      Eischeid, Isabell; Madsen, Jesper; Ims, Rolf Anker; Nolet, Bart A.; Pedersen, Åshild Ønvik; Schreven, Kees H.T.; Soininen, Eeva Marjatta; Yoccoz, Nigel Gilles; Ravolainen, Virve (Peer reviewed; Journal article, 2023-12-17)
      Arctic tundra vegetation is affected by rapid climatic change and fluctuating herbivore population sizes. Broad-billed geese, after their arrival in spring, feed intensively on belowground rhizomes, thereby disturbing soil, ...
