The helminth fauna of brown trout (Salmo trutta) in the lake, Øvre Heimdalsvatn, before and after the establishment of a large population of the invasive species, European minnow (Phoxinus phoxinus)
(Master thesis, 2012-06-18)The objective of this thesis is to compare the parasite fauna of brown trout (Salmo trutta) in the lake, Øvre Heimdalsvatn, before and after the establishment of a large population of the invasive species, the European ... -
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 litter on soil quality and regeneration of Norway spruce (Picea abies (L.) H. Karst) and European beech (Fagus sylvatica (L.) : an experimental approach
(Master thesis, 2016-08-31)During the next decades, the climate in Scandinavia is predicted to become wetter and warmer. This change will alter the ecosystems, and implies a possible transformation from Norway spruce (Picea abies) to European beech ... -
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 flower resources and habitat configuration for bumblebees (Bombus) in a fragmented agricultural landscape
(Master thesis, 2013-08-23)Bumblebees are important pollinators of crops and wild flowers, and the observed decrease in natural bumblebee populations are therefore an increasing cause of concern. The aim of this thesis was to evaluate how ... -
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 importance of weather for abundant saproxylic beetles : an indication of responses to climate change
(Master thesis, 2015-08-07)The effects of climate change are expected to be seen across the globe, as well as impact many different species, including saproxylic beetles. Considering their importance for both biodiversity and as providers of ecosystem ... -
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 invasive alien plant control on the foraging habitat quality of the Mauritian flying fox (Pteropus niger)
(Master thesis, 2017)The last surviving Mauritian fruit bat species, Pteropus niger, although endangered, provides essential seed dispersal and pollination services for the threatened native flora. However, their foraging habitats in native ... -
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 Norwegian market for natur based tourism products : characteristics and implications for segmentation and product development
(PhD Thesis;2011:54, Doctoral thesis, 2011)Nature based tourism is often considered as an important area for rural municipalities when traditional industries such as agriculture, forestry and manufacturing has been downgraded and rationalised because they are no ... -
The place of National Park and ecotourism in Norway
(Master thesis, 2015-08-10)T ourism is a big and growing business all over the world. In recent decades, Norway promotes tourism in general and ecotourism in particular, as a product, as well as the improvement of quality and the development ... -
The predictive accuracy of two Swedish nitrogen forest fertilization functions evaluated on norwegian fertilization experiments, and preliminary analyses of economic return
(Master thesis, 2012-09-19)This thesis paper addresses the accuracy of two Swedish predictive functions for the impact of nitrogen (N) fertilization on tree growth, in relation to the Norwegian fertilization data on Norway spruce (Picea abies (L.) ... -
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. ... -
