Arthropod biomass and abundances in mature clear-cut versus mature near-natural boreal forests in southeastern Norway
Jørgensen, Oda (Master thesis, 2022)The loss of biodiversity in forest ecosystems has led to a discussion on conservation-oriented forest management, particularly in intensively managed boreal forests of the northern hemisphere. Clear-cutting is the most ... -
Arthropod succession following a mass mortality event of reindeer (Rangifer tarandus) in an Alpine ecosystem
Westermann, Lina (Master thesis, 2020)Carcasses are of great ecological importance, especially as a resource for arthropods. However, many aspects of carrion ecology remain to be investigated. One of these aspects is the ecological significance of mass mortality ... -
Bats, insects and weather : spatial-temporal trends on a boreal forest wind facility in Norway
Johns, Sarah Elizabeth (Master thesis, 2021)Bats and insects are valuable indicators of ecosystem health. As both organisms are potential bioindicators, it is important to understand how they interact with each other and their environment. Bats and insects are facing ... -
Bed bug activity during heat treatments, and physiological effects among surviving individuals
Saunders, Marius (Master thesis, 2018)Simulated heat treatments with different heating rates were performed in experimental climate chambers to study bed bug behavior during rising heat. In addition, detrimental effects of these short time exposures to sub-lethal ... -
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 ... -
Biller i Østmarka : hvordan vernestatus, mengde død ved og skogens åpenhet påvirker billesamfunnet
Reenskaug, Christine (Master thesis, 2020)Insekter utgjør en stor andel av de vedlevende artene i skogen og i Skandinavia finnes det rundt 1250 billearter knyttet til død ved. Det er mange nisjer i død ved, og vi finner ofte flere vedlevende billearter der det er ... -
Change in arthropod communities following a mass death incident of reindeer at Hardangervidda
Granum, Heidi Mørkhagen (Master thesis, 2019)Decomposition of dead material is a vital part of ecology, and an important process in every ecosystem. Dead animals are likely to play a major part in sustaining species that specialize on scavenging. The highly nutrient ... -
Comparing distribution of willow psyllids (Cacopsylla spp.) on Salix lapponum in 2018 with 1995 along an alpine altitudinal gradient
Selvig, Kristoffer (Master thesis, 2019)The psyllid (Cacopsylla spp.) population on Salix lapponum in the alpine areas of southern Norway, in an altitudinal gradient between Haugastøl and Finse, were thoroughly studied in 1995. The results were presented and ... -
Comparison of EIQ and PRIMET models to assaee the impact of pesticide use of smallholder cocoa production in western Ghana
Paintsil, Joel Kweku Burah (Master thesis, 2017)Risk assessments of agricultural systems in Ghana are often performed to ascertain the level of risk posed by agrochemicals released during application. In this thesis two risk assessment models EIQ and PRIMET are compared ... -
Contrasting drivers of community‐level trait variation for vascular plants, lichens and bryophytes across an elevational gradient
Roos, Ruben Erik; van Zuijlen, Kristel; Birkemoe, Tone; Klanderud, Kari; Lang, Simone; Bokhorst, Stef; Wardle, David A.; Asplund, Johan (Peer reviewed; Journal article, 2019)Across environmental gradients, community‐level functional traits of plants can change due to species turnover, intraspecific variation and their covariation. Studies on vascular plants suggest that species turnover is the ... -
Divergent responses of functional diversity to an elevational gradient for vascular plants, bryophytes and lichens
Asplund, Johan; van Zuijlen, Kristel; Roos, Ruben Erik; Birkemoe, Tone; Klanderud, Kari; Lang, Simone; Wardle, David A. (Peer reviewed; Journal article, 2021)Question: Cold environments are stressful for vascular plants, and stress-tolerant non-vascular photoautotrophs, e.g. bryophytes and lichens, become relatively more important as competition from vascular plants decreases ... -
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 ... -
