      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 ...
    • Effects of mountain biking versus hiking on trails under different environmental conditions 

      Evju, Marianne; Hagen, Dagmar; Jokerud, Mari; Olsen, Siri Lie; Selvaag, Sofie Kjendlie; Vistad, Odd Inge (Peer reviewed; Journal article, 2020)
      Recreational use of nature areas is increasing worldwide. All trail-based activities have a certain degradation effect on vegetation and soil, and conflicts between conservation values and recreation may occur. Controversy ...
    • Exclusion of invertebrates influences saprotrophic fungal community and wood decay rate in an experimental field study 

      Jacobsen, Rannveig Margrete; Sverdrup-Thygeson, Anne; Kauserud, Håvard; Mundra, Sunil; Birkemoe, Tone (Journal article; Peer reviewed, 2018)
      1. Decomposer communities perform an essential ecosystem function by recycling nutrients. However, the effect of higher trophic levels on microbial decomposer communities and rate of decomposition is poorly understood. We ...
    • Long-term effects of colonization–extinction dynamics of generalist versus specialist wood-decaying fungi 

      Moor, Helen; Nordén, Jenni; Pentitilä, Reijo; Siitonen, Juha; Snäll, Tord (Peer reviewed; Journal article, 2020)
      1. Long-term metapopulation persistence is mediated by the dynamics of colonization and extinction. To understand and predict future species occupancy in changing landscapes, we must account for the dynamic rates that shape ...
    • Scavenging on a pulsed resource: quality matters for corvids but density for mammals 

      Gomo, Gjermund; Mattisson, Jenny; Hagen, Bjørn Roar; Moa, Pål Fossland; Willebrand, Tomas (Journal article; Peer reviewed, 2017)
      Background: Human food subsidies can provide predictable food sources in large quantities for wildlife species worldwide. In the boreal forest of Fennoscandia, gut piles from moose (Alces alces) harvest provide a potentially ...
