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 (Journal article; Peer reviewed, 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 ... -
DNA metabarcoding reveals host-specific communities of arthropods residing in fungal fruit bodies
Lunde, Lisa Fagerli; Birkemoe, Tone; Kauserud, Håvard; Boddy, Lynne; Jacobsen, Rannveig Margrete; Morgado, Luis; Sverdrup-Thygeson, Anne; Maurice, Sundy (Peer reviewed; Journal article, 2022)Biological communities within living organisms are structured by their host’s traits. How host traits affect biodiversity and community composition is poorly explored for some associations, such as arthropods within fungal ... -
DNA metabarcoding reveals host-specific communities of arthropods residing in fungal fruit bodies
Lunde, Lisa Fagerli; Birkemoe, Tone; Kauserud, Håvard; Boddy, Lynne; Jacobsen, Rannveig Margrete; Morgado, Luis; Sverdrup-Thygeson, Anne; Maurice, Sundy (Peer reviewed; Journal article, 2022) -
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 ... -
The importance of invertebrates on fungi in dead wood
Lunde, Lisa Fagerli (PhD Thesis;2022:43, Doctoral thesis, 2022)Dead wood is an important energy source in boreal forests and it hosts a high biodiversity dominated by fungi and invertebrates. Wood decay fungi are the initial decomposers of dead wood and invertebrates interact with ... -
Legacies of invertebrate exclusion and tree secondary metabolites control fungal communities in dead wood
Lunde, Lisa Fagerli; Jacobsen, Rannveig Margrete; Kauserud, Håvard; Boddy, Lynne; Nybakken, Line; Sverdrup-Thygeson, Anne; Birkemoe, Tone (Peer reviewed; Journal article, 2022) -
Legacies of invertebrate exclusion and tree secondary metabolites control fungal communities in dead wood
Lunde, Lisa Fagerli; Jacobsen, Rannveig Margrete; Kauserud, Håvard; Boddy, Lynne; Nybakken, Line; Sverdrup-Thygeson, Anne; Birkemoe, Tone (Peer reviewed; Journal article, 2022) -
Moth species richness and diversity decline in a 30‑year time series in Norway, irrespective of species’ latitudinal range extent and habitat
Burner, Ryan C.; Selås, Vidar; Kobro, Sverre; Jacobsen, Rannveig Margrete; Sverdrup-Thygeson, Anne (Peer reviewed; Journal article, 2021)Introduction Insects are reported to be in decline around the globe, but long-term datasets are rare. The causes of these trends are elusive, with changes in land use and climate among the top candidates. Yet if species ... -

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 ... -
Saproxylic insects influence community assembly and succession of fungi in dead wood
Jacobsen, Rannveig Margrete (PhD thesis;2017:88, Doctoral thesis, 2017)Insekter og sopp utgjør en stor andel av alle arter på landjorda, og leverer viktige økosystemtjenester som pollinering, karbonlagring og nedbrytning. Sopp er spesielt viktig for nedbrytning av plantemateriale, siden de ... -
Veteran trees in decline: Stratified national monitoring of oaks in Norway
Jacobsen, Rannveig Margrete; Birkemoe, Tone; Evju, Marianne; Skarpaas, Olav; Sverdrup-Thygeson, Anne (Peer reviewed; Journal article, 2022)Old veteran trees function as biodiversity hotspots in both forests and open landscapes, and protecting such trees is an important measure to halt loss of biodiversity. Nevertheless, the number of veteran trees continues ...
