Ecological condition, alpha diversity, abundance and functional groups in macroinvertebrate communities of 15 tributaries in the Verdal watershed
(Master thesis, 2022)Streams and rivers are some of the most degraded and threatened ecosystems in a global perspective. There are several factors influencing declines in biodiversity globally, with the most driving agents being pollution, ... -
The effect of artificial light and latitude on foraging activity in resident passerines in Northern Europe
(Master thesis, 2020)Over the last couple of decades, there has been an increasing interest in the ecological consequences of artificial light on wildlife. At northern latitudes, winter is characterized by short days and low temperatures, ... -
Effect of autumn warming on the rate of senescence in Svalbard plants : an experimental approach with relevance for Svalbard reindeer
(Master thesis, 2022)Phenology is a biological trait sensitive to global warming. Climate change scenarios predict a three-fold increase in temperature and altered rainfall for polar regions. The Svalbard Archipelago, situated at 780 North, ... -
Effect of Conservation Agriculture and Biochar on Soil Hydraulic Properties in a Ugandan Plinthosol
(Master thesis, 2023)Conservation agriculture (CA) is regarded as a robust and resilient agricultural practice, able to meet the challenges related to climate change. Conservation farming in combination with biochar (BC) has gained increased ... -
Effect of Elevation Differences in Alpine Insect Activity on Silene Acaulis at Finse, Norway
(Master thesis, 2021)Global annual average temperature has increased since the industrial revolution and is predicted to continue to increase in the future resulting in altered species distributions. Alpine ecosystems are particularly vulnerable ... -
Effect of experimental warming on Dryas octopetala- dominated vegetation in High Arctic versus alpine ecosystems
(Master thesis, 2024)As a consequence of climate change, colder regions such as the Arctic and alpine areas are experiencing a higher rate of warming compared to the global average. The effect of warming varies across the tundra biome, and the ... -
Effect of farmland type and vegetation height on habitat use and breeding success of northern lapwings in south-east Norway
(Master thesis, 2020)Habitat use is a key element to understanding how endangered species should be protected from further decline. The northern lapwing (Vanellus vanellus) is a red-listed farmland species threatened by multiple factors such ... -
Effect of grazing in Norwegian outfields related to the quantity and quality of soil organic carbon and other soil properties
(Master thesis, 2022)Utilization of the outfield for grazing have long traditions in Norway. Not only as a pasture, but also mowed to provide food for the winter (Rekdal & Angeloff, 2021). From 1949 to 1999, grazing in Norway changed from ... -
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 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 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 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 ... -
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 ... -
Effects of Biochar and Crop Rotation with Maize and Pigeon Pea on soil Phosphorous Availability in Chipata and Mambwe, Zambia
(Master thesis, 2024)Sub- Saharan Africa (SSA) faces significant challenges in agricultural production due to soil degradation, costly fertilizers, and reliance on precipitation. Conservation agriculture has a potential to mitigate these ... -
Effects of biochar and crop rotation with pigeon pea on soil phosphorus availability in Mkushi and Kaom, Zambia
(Master thesis, 2022)Low phosphorus (P) availability in sub-Sahara African agriculture strongly effects yield and food production negatively. As fertilizer prices increases, the need for human interventions to increase soil plant available P ... -
