Apple tree phenology in relation to temperature in Sauherad (Norway)
(Master thesis, 2018)Temperature plays a crucial role for the phenological development of plants and since past few decades Earth’s temperature is increasing. Plants are responding to this rise in temperature, through variations in their ... -
Canines as biodetectors for conservational work: can they discriminate Rock ptarmigan from Willow ptarmigan?
(Master thesis, 2018)The main goals for conservation biology is to document the full range of biological diversity and human impact, along with developing plans, approaches and measures to prevent extinction of species. Alpine and arctic bird ... -
Effects of sheep grazing on alpine vegetation, a study from Forrolhogna National Park in Central Norway
(Master thesis, 2018)Alpine areas in Norway have a long history of domestic herbivory, and understanding the impact of grazing on alpine vegetation is therefore important for sustainable management of these areas. Domestic herbivory has the ... -
Environmental and floristic differences between three contrasting study areas in an alpine ecosystem: Hardangervidda National Park, Southern Norway
(Master thesis, 2018)Alpine vegetation has been the main focus for many botanists during decades and it has been shown that snow is one of the most important variables explaining vegetation patterns in mountain ecosystems. However, other ... -
Large-scale geographical effect of isolation on adult sex ratios in the rock ptarmigan (Lagopus muta)
(Master thesis, 2018)Recent advances in sex ratio theory show that increased habitat isolation might be causing male-biased adult sex ratios (ASRs) in avian populations. This has raised concerns, since skewed ASRs are frequently seen in small ... -
Population structure of brown trout (Salmo trutta), a host of freshwater pearl mussel (Margaritifera margaritifera) in Lake Norsjø tributaries
(Master thesis, 2018)Brown trout (Salmo trutta) is one of a few suitable host species for endangered freshwater pearl mussel (Margaritifera margaritifera). Freshwater pearl mussel larvae (glochidia) are obligate parasites. Glochidia, must ... -
Redd Site Micro-Habitat Selection and Quantitative Analyis for Large Brown Trout in the Tokkeåi River Telemark, Norway
(Master thesis, 2018)The study of redd site microhabitat selection is very important for successful conservation and management of large brown trout. Number of redds is quantified by several reports before but this research has done microstudy ... -
Vertical distribution of ticks in southern Norway
(Master thesis, 2018)Due to climatic changes, plant and animal species have expanded their range vertically. One might therefore expect to find species at a higher elevation point than usual. By using both live and lethal traps, small mammals ...
