The Holocene vegetation history of an isolated, high-arctic plant diversity hot spot
(Master thesis, 2018)Through high throughput sequencing of ancient, environmental DNA collected from lake sediment cores (sedaDNA), this study revealed postglacial vegetation change during the last ~12.000 years in a high-Arctic plant diversity ... -
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 ... -
The impact of planting basins under conservation farming with and without biochar on aggregate stability, soil organic carbon, and pH in Zambian Acrisols
(Master thesis, 2018)Conservation Farming (CF) in Sub-Saharan Africa (SSA), including reduced tillage, return of crop residue, and crop rotation, has been found to increase maize yields in rain-fed agriculture. In combination with the application ... -
The importance of microclimate and plant species richness for alpine arthropods in a Dryas heath at Finse
(Master thesis, 2023)Alpine ecosystems are characterized by low temperatures, strong winds, and high solar radiation, which can lead to harsh living conditions for flora and fauna. As climate changes, larger climatic variations and the number ... -
The Influence of Body Size on the Foraging Strategy of the Male African Savannah Elephant in Makgadikgadi Pans National Park, Botswana
(Master thesis, 2023)Differences in feeding behaviour and species selection, due to the difference in body size, between the sexes for the African savannah elephants (Loxodonta africana) is well documented. However, there are also substantial ... -
The influence of nest-site limitation on the species richness and abundance of bees : linking biodiversity and geology
(Master thesis, 2018)There is mounting evidence of declines in global biodiversity. Declining wild bee populations are subject to concern because bees are considered the most important pollinators worldwide, contributing to the production of ... -
The influence of nesting resources on bee-flower interactions, revealed through functional traits, network structure and geology
(Master thesis, 2018)Bees are the major pollinators in most parts of the world, but their diversity have declined as a consequence of environmental changes, during the last century. To counteract this decline, an understanding of the bees and ... -
The presence of microplastics on the Norwegian Continental Shelf and in Rio Almendares, Havana
(Master thesis, 2018)Microplastics are becoming more frequently detected in all natural environments worldwide as global demand for plastic production continues to rise and studies related to microplastic research are becoming more prevalent. ... -
The role of wildlife tourism in conservation in Norway
(Master thesis, 2017)Nature-based tourism is a growing tendency in Norway and in the rest of the world. One of the sectors that seem to grow most rapidly is wildlife watching. Based on existing data from quantitative and qualitative research ... -
The Rothschild's giraffe as a potential biological controller of invasive native Acacia species in Lake Mburo National Park, Uganda
(Master thesis, 2018)Shrub and woody encroachment can have serious ecological impacts and is an increasingly common problem in many ecosystems, from the African savanna to the Arctic. Lake Mburo National Park in Uganda is experiencing severe ... -
The Short-Term Impact of Military Jet Flight Activity on Semi-Domestic Reindeer in the Two Reindeer Districts Grovfjord and Tjeldøya
(Master thesis, 2023)Rangifer tarandus (hereby referred to as reindeer) are a migratory species with a diet changing throughout the year, and survival and reproduction depend on access to, and time for optimal grazing. Reindeer can be disturbed ... -
The transfer of radiocesium in coastal waters : radiocesium tracer to investigate mixing zone processes in brackish waters
(Master thesis, 2019)In the event of a reactor accident, debris plumes containing artificially produced radionuclides could impose a great risk for the environment in distances far from the accident site. Radionuclides can enter the marine ... -
The use of animal-borne video systems to study foraging ecology and diel behaviour : a review and case study on the Scandinavian brown bear (Ursus arctos)
(Master thesis, 2019)Animal-borne video systems, also known as Crittercams, were developed by Greg Marshall in the 1980s to capture video footage from the animal’s perspective. Primarily deployed on marine species, such as attached to the ... -
Thermoregulatory behavior in a warming Arctic : bed site selection by Svalbard reindeer (Rangifer tarandus platyrhynchus) in summer
(Master thesis, 2018)Climate change leads to rapidly increasing mean temperatures, and the climate warming is particularly pronounced in the Arctic. In Arctic mammals with long generation times, evolution of physiological and morphological ... -
Tilvekstreaksjoner på enkelttrenivå hos gran og furu etter tynning
(Master thesis, 2021)Tynning reduserer konkurransen i et bestand og øker tilveksten hos de gjenværende trærne. Flere studier har undersøkt tynningsreaksjoner på enkelttrenivå og vist en større absolutt tynningsreaksjon hos større trær sammenliknet ... -
To ban or not to ban? : spatial and temporal effects of banning long-term supplementary feeding on red deer space use, forest browsing damage and the performance and nitrogen content of bilberry plants
(Master thesis, 2020)Supplementary feeding (i.e. diversionary feeding) of red deer (Cervus elaphus) and other cervids is a widespread tool in wildlife management in Europe and North America. In 2016 supplementary feeding was banned in Norway ... -
Tortricid pests (Lepidoptera: Tortricidae) in apple orchards of South-Eastern Norway surveyed by pheromone-baited traps
(Master thesis, 2020)The trend of minimizing pesticide usage in agriculture leads scientists to think about alternatives of how pest numbers can be reduced. The tortricid moths (Lepidoptera: Tortricidae) is a group of insects responsible for ... -
The toxicity of depleted uranium and uranium nanoparticles in the nematode Caenorhabditis elegans
(Master thesis, 2020)In recent years, nanoparticles have been the subject of intensive research and have been shown to have unique toxic properties compared to bulk material. Nevertheless their toxic mechanisms, and thus their ecotoxicological ... -
Trace metal speciation and uptake in Atlantic salmon (Salmo salar) in coastal water
(Master thesis, 2020)Estuarine environments have a high risk of metal pollution due to the influx from rivers. Freshwater from rivers mixed with seawater in coastal areas gives varied and complex water chemistry. In the estuarine environment ... -
Transfer of river-discharged Cs-137 in estuaries : a case study from Vefsna river and the Vefsnfjord in Nordland, Norway
