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 ... -
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 ... -
Effect of Elevation Differences in Alpine Insect Activity on Silene Acaulis at Finse, Norway
Hovde, Krister (Master thesis, 2021)Global annual average temperature has increased since the industrial revolution and is predicted to continue to increase in the future resulting in altered species distributions. Alpine ecosystems are particularly vulnerable ... -
Effects of elevation on the lichen community palatability in an alpine ecosystem
Levavasseur, Gaspard Paul Yves Marie (Master thesis, 2021)Lichens are present in almost all terrestrial ecosystems, and in some of them, they are the main primary producers. Most studies focus on vascular plant communities, even studies on ecosystems where lichens represent an ... -
Er vegetasjon og insektsamfunnet forskjellig rundt gamle og unge eiker? : en sammenligning av vegetasjon, biller og veps rundt gamle og unge eiker i Vestfold og Telemark, Norge
Hansen, Anna Sophie (Master thesis, 2019)Store, grove eiketrær er viktige habitat for veldig mange forskjellige arter, fra fugler til insekter. Nedgang i antall eiker har ført til at artene som har spesialisert seg på eiker har blitt mindre vanlige, noen til og ... -
Finnes det flere leddyr i barken av gamle enn unge eiketrær?
Vereide, Linnea Karoline (Master thesis, 2019)Store gamle eiketrær (Quercus spp.) er i nedgang over hele verden. Dette er lite gunstig da gamle eiker har et rikt antall mikrohabitater som er viktig for mange sjeldne og truede arter. Mikrohabitater i barken er mindre ... -
Long-term effects of clear-cut forestry on beetle community diversity in boreal forests of southeastern Norway
Lish, Geneva Nuttall (Master thesis, 2022)Forest management regimes have led to global biodiversity declines. Norwegian boreal spruce-forests have been negatively impacted by clear-cutting for the last 70 years, a practice which shifts structural conditions of a ... -
Measurement of 90Sr in Chernobyl arthropods
Ormaasen, Ivar (Master thesis, 2021)Following the Chernobyl accident, the areas around the Chernobyl Nuclear Power Plant (ChNPP) were contaminated with many radionuclides, including the fission product 90Sr. Because of its long half-life and chemical similarity ... -
Spore production and beetle visitation on the polypore Fomitopsis pinnicola
Wegger, Hermann Hallerud (Master thesis, 2021)Insects and fungi are important parts of dead wood systems. Polypores, the main structural decomposers of dead wood, have fruiting bodies frequently visited by insects. This could potentially be important for spore dispersal, ... -
Use of time-lapse cameras to monitor beetle activity on fruiting bodies of Fomitopsis pinicola
Ferkingstad, Bendik Johansen (Master thesis, 2020)Insects and fungi are the major contributors to forest biodiversity. It is apparent that insects have an ecologically important effect on fungal communities in dead wood systems. Beetles frequently visit the fruiting bodies ...
