A major shift to the retention approach for forestry can help resolve some global forest sustainability issues
Lindenmayer, D.B.; Franklin, J.F.; Lõhmus, A.; Baker, S.C.; Bauhus, J.; Beese, W.; Brodie, A.; Kiehl, B.; Kouki, J.; Pastur, G. Martínez; Messier, C.; Neyland, M.; Palik, B.; Sverdrup-Thygeson, Anne; Volney, J.; Wayne, A.; Gustafsson, L. (Journal article; Peer reviewed, 2012)Approximately 85% of the global forest estate is neither formally protected nor in areas dedicated to intensive wood production (e.g., plantations). Given the spatial extent of unprotected forests, finding management ... -

At which spatial and temporal scales can fungi indicate habitat connectivity?
Nordén, Jenni; Åström, Jens; Josefsson, Torbjörn; Blumentrath, Stefan; Ovaskainen, Otso; Sverdrup-Thygeson, Anne; Nordén, Björn (Journal article; Peer reviewed, 2018)Isolation of habitats in space and time affects species globally and in a multitude of ecosystems. It is however often difficult to assess the level of isolation from the point of view of the focal species. Indicator species ... -
Beetles in hollow oaks : the effects of traits on community structure
Hatlevoll, Kristina (Master thesis, 2020)Habitat fragmentation and habitat loss have long been acknowledged as two of the most important drivers of biodiversity loss all over the world. A way to preserve biodiversity is to protect the remaining hotspots. Hotspots ... -
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 ... -
Biller i hule eiker i Vestfold, Telemark og Agder
Pilskog, Hanne Eik; Sverdrup-Thygeson, Anne; Birkemoe, Tone (MINA fagrapport;27, Report, 2014)Hule eiker er en utvalgt naturtype under naturmangfoldsloven og hotspot‐habitat for insekter, lav og sopp. Hule eiker er levested for mange sjeldne arter. Vindusfeller ble brukt til å kartlegge billefaunaen i 32 hule ... -

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 ... -

Do insect fungivores that visit polypore cafes aid sporedispersal?
Seres, Kristian Vicktor (Master thesis, 2018)Dispersal of wood-decaying fungi has been well studied, but the importance of insects for the dispersal of spores are less documented In this study I sampled beetles from red belt conk, tinder fungus and aspen bracket by ... -
Does species richness and abundance of saproxylic beetles differ between old near-natural and old managed forest in south-eastern Norway?
Norseng, Charlotte (Master thesis, 2016-08-31)Humans have altered almost all forests on earth through the need for forest resources. Several scientific papers show that forestry is a threat to the biodiversity and that many forest species will go extinct unless drastic ... -
Effect of Habitat Size, Quality, and Isolation on Functional Groups of Beetles in Hollow Oaks
Pilskog, Hanne Eik; Birkemoe, Tone; Framstad, Erik; Sverdrup-Thygeson, Anne (Journal article; Peer reviewed, 2016) -
Effects of climate, historical logging and spatial scales on beetles in hollow oaks
Pilskog, Hanne Eik (PhD Thesis;2016:90, Doctoral thesis, 2016)Veteran trees are keystone structures and important biodiversity habitats, but they are declining on a global scale. In Europe, old oaks (Quercus spp.) are one of the most important habitat trees for biodiversity, yet the ... -
Environmental conditions alter successional trajectories on an ephemeral resource: a field experiment with beetles in dead wood
Vindstad, Ole Petter Laksforsmo; Birkemoe, Tone; Ims, Rolf Anker; Sverdrup-Thygeson, Anne (Peer reviewed; Journal article, 2020)Successional processes can be observed for many organisms and resources, but most studies of succession have focused on plants. A general framework has been proposed, advocating that successional patterns in species turnover ... -
Er skogkartlegging med flybåren laser en mer hensiktsmessig måte for å finne områder med naturskog, enn Natur i Norge (NiN)'s naturskogkriterier? : en gjennomgang av to metoder for å skille gammel plukkhogd skog fra gammel flatehogd skog
Skeie, Margrethe Fønhus (Master thesis, 2019)Skogen i Norge har ulike naturgitte forutsetninger på regional skala, hvor klima, vekstforhold og skogbrukshistorie påvirker det biologiske mangfoldet. Fragmentering av skogområder, langtransportert forurensning, skogbruk, ... -
