Short-time effects of water sprinkling on the two-spotted spider mite predator Phytoseiulus persimilis in strawberry
(Master thesis, 2018)Combining two tools for an integrated pest management (IPM) was the reason for investigating the potential use of predatory mites (Phytoseiulus persimilis) in addition to water sprinklers in order to reduce spider mite ... -
Livelihood and home garden improvements : strategies to reduce destructive fuelwood harvests from the Manas National Park, India
(Master thesis, 2018)Fuelwood is the primary energy source for cooking in rural India. Natural forests in protected areas are often accessed by local people to collect this resource. However, the extraction of wood destructs forests, threatens ... -
Alunskifer : bergarters svarte får : en redegjørelse for forurensningspotensialet til alunskifer, med særlig fokus på uran
(Master thesis, 2018)It has been acknowledged for a long time, that alum shale is a rock that causes trouble. Already in 1957, reports said that the rock caused technical problems, because it started to swell beneath buildings. An even greater ... -
Rehydration and photosynthetic reactivation of old forest cephalolichen members of Lobaria in humid air
(Master thesis, 2018)Most lichens tolerate desiccation, yet sufficient hydration remains a general prerequisite to photosynthesis and growth. Species-specific morphologies likely reflect important hydration traits and may therefore provide ... -
The hunt for maternity colonies : a pilot study of using radio telemetry to track bats in southeast Norway
(Master thesis, 2018)There is still a gap of knowledge regarding bats in Norway. More studies are needed to explore which habitats are important for the maternity colonies, and which methods are most suited to find them. This is especially ... -
