Effect of macrophyte removal on CO2 emissions in the river Otra, Norway
(Master thesis, 2021)The main goal of this study is to examine how macrophyte removal affects CO2 emissions in rivers with a secondary aim of quantifying CO2 concentrations and emissions in the river over the course of 24 hours. The study was ... -
Effect of mountain biking on red deer (Cervus elaphus) in Kaupanger, Norway
(Master thesis, 2016-08-31)Human outdoor activities, like mountain biking, often affect animal behaviour. Ungulates might avoid roads and trails, and increase their avoidance with increasing human activity. Recently, biking on forest trails has ... -
Effect of nanoplastics in the marine organism Tisbe battagliai
(Master thesis, 2019)Plastic is a material made out of polymer chains derived from oil and gas, and together with additives these polymers have numerous applications. Plastic is used in daily life as wrapping around food, in cosmetics and in ... -
Effect of Neozygites floridana infection in Tetranychus urticae females on sexual behavior of males
(Master thesis, 2012-11-16)The entomopathogenic fungus Neozygites floridana infects and kills the two-spotted spider mite, Tetranychus urticae, an important herbivorous pest worldwide. The fungal development stages in/ on the cadaver (mite infected ... -
Effect of nitrogen fertilization on decomposition in boreal forest
(Master thesis, 2021)Anthropogenic activities have resulted in escalating deposition of nitrogen in many forms that impact several aspects of ecosystem especially lying on boreal region where N is a limiting factor for tree growth. Although N ... -
Effect of riparian vegetation cover and season on aquatic macroinvertebrate assemblages in the Ecuadorian Andes
(Master thesis, 2013-08-12)The purpose of this study was to investigate the effects of season and changes in the riparian vegetation cover on diversity, structure, temporal variability, and trophic structure of aquatic macroinvertebrate assemblage ... -
Effect of salmon lice (Lepeophtheirus salmonis) infestations on the behaviour of prematurely returned sea trout (Salmo trutta) in the Hardangerfjord
(Master thesis, 2022)The expansion of the salmon farming industry along the Northern coasts has caused a higher concentration of salmon lice (Lepeophtheirus salmonis) in the coastal waters and fjords. There has been observed that Sea trout ... -
Effect of Season and Habitat on Two Congeneric Bat Species in a Fragmented Forest Landscape, Central Amazon, Brazil
(Master thesis, 2022)Bats are an important component of Amazonian mammal communities but are often ignored during conventional biodiversity assessments. Much is therefore unknown regarding spatial and temporal forest use and the partitioning ... -
Effect of seed treatment with putative defence priming chemicals on defence-related gene expression and pathogen resistance in Norway spruce (Picea abies) seedlings
(Master thesis, 2020)Chemical seed treatment may be a simple method to protect conifer seedlings from pests and pathogens in plant nurseries and forest stands. In this study, I tested the ability of eight putative defence priming chemicals ... -
The effect of Silene acaulis on soil bacterial communities across elevational and latitudinal gradients in Scandinavia
(Master thesis, 2022)Microbes are ubiquitous, extremely diverse, and contribute to important ecosystem functions. Soil bacterial communities, in particular, play an important role in carbon and nutrient cycling, through decomposition and carbon ... -
The effect of tunnel construction particles on Daphnia magna
(Master thesis, 2022)Particles originating from drilling and blasting during tunnel construction have the potential to end up in the environment, however, there is a knowledge gap concerning the effect of these particles on aquatic biota. In ... -
Effect of Tunnel Wash Water on Survival, Growth and Migration of Atlantic Salmon (Salmo salar) and Brown Trout (Salmo Salar) in River Årungselva
(Master thesis, 2016-04-05)Tunnel wash water is frequently released to the river Årungselva through a sedimentation pond. This tunnel wash water may cause harm to the fish through intrinsic and extrinsic toxic effects. A reduction in growth have ... -
Effect of vegetation encroachment on Macrotermes subhyalinus (Rambur) activity and associated mound vegetation, in Lake Mburo National Park,Uganda
(Master thesis, 2016-08-31)Termites play a key-role in the savanna ecosystem. As primary producers and decomposers, they transport soil nutrients vertically and horizontally, creating a more heterogeneous landscape. Increased canopy cover will shade ... -
Effects from environmental factors and individual characters on activity and depth use in a Northern pike (Esox lucius) population subjected to recreational fishing : an acoustic telemetry study
(Master thesis, 2018)Northern pike (Esox lucius) is a common top- predator in freshwater systems all over the Northern Hemisphere. For centuries it has been a popular target for recreational anglers. In many freshwater ecosystems, recreational ... -
