Beetles provide directed dispersal of viable spores of a keystone wood decay fungus
Lunde, Lisa Fagerli; Boddy, Lynne; Sverdrup-Thygeson, Anne; Jacobsen, Rannveig Margrete; Kauserud, Håvard; Birkemoe, Tone (Peer reviewed; Journal article, 2023)Wood decay fungi are considered to be dispersed by wind, but dispersal by animals may also be important, and more so in managed forests where dead wood is scarce. We investigated whether beetles could disperse spores of ... -
Designing a surveillance program for early detection of alien plants and insects in Norway
Sandercock, Brett; Davey, Marie Louise; Endrestøl, Anders; Blaalid, Rakel; Fossøy, Frode; Hegre, Hanne; Majaneva, Markus; Often, Anders; Åström, Jens; Jacobsen, Rannveig Margrete (Peer reviewed; Journal article, 2022)Naturalized species of alien plants and animals comprise < 3% of biodiversity recorded in Norway but have had major impacts on natural ecosystems through displacement of native species. Encroachment of alien species has ... -
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 ... -

Near-natural forests harbor richer saproxylic beetle communities than those in intensively managed forests
Jacobsen, Rannveig Margrete; Burner, Ryan C.; Olsen, Siri Lie; Skarpaas, Olav; Sverdrup-Thygeson, Anne (Journal article, 2020)Globally, boreal forests cover 33 percent of Earth's forested area, constitute the largest terrestrial carbon source, and house an important biodiversity of forest-dependent species, many of which are saproxylic taxa reliant ... -
Revealing hidden insect–fungus interactions; moderately specialized, modular and anti-nested detritivore networks
Jacobsen, Rannveig Margrete; Sverdrup-Thygeson, Anne; Kauserud, Håvard; Birkemoe, Tone (Journal article; Peer reviewed, 2018)Ecological networks are composed of interacting communities that influence ecosystem structure and function. Fungi are the driving force for ecosystem processes such as decomposition and carbon sequestration in terrestrial ... -
Tidlig oppdagelse av fremmede arter – om å finne nåla i høystakken
