Effects of low frequency acoustic pulses on startle behaviour and EOD activity in elephantnose fish (Gnathonemus petersii)
(Master thesis, 2016-11-21)The sensory system initiating C-response and electric organ discharge (EOD) response in the hearing specialist elephantnose fish was studied in an experimental swing chamber set-up. The swing chamber is specially designed ... -
Effects of macrophyte removal on habitat use of brown trout (Salmo trutta)
(Master thesis, 2021)Aquatic macrophytes play an important role in freshwater ecosystems. They are primary producers, promote good water quality, and provide food and habitats for various organisms, including fish. When macrophytes have ... -
EFFECTS OF MICROBIOME ON CONIFER HEALTH AND RESISTANCE TO BIOTIC AND ABIOTIC STRESS: A SYSTEMATIC REVIEW
(Master thesis, 2023)ABSTRACT The dynamics of plant-microbiome interactions under different stress conditions are important to understand in order to elucidate the mechanisms underlying forest decline and tree mortality. This study aims to ... -
Effects of nutrient enrichment on stream benthos override those of fine sediment addition : a flume experiment
(Master thesis, 2016-11-21)1. Agricultural runoff greatly contributes to stream eutrophication and sedimentation, which in turn can severely impact the benthic algal and invertebrate communities. Our aim was to determine the combined and individual ... -
Effects of pasture tree cover on cattle behaviour in a small-scale farming system in Rivas, Nicaragua
(Master thesis, 2012-08-02)Abstract Rapid population growth and poverty with the resulting over-exploitation of land, threatens to further degrade land in rural areas of Nicaragua. Silvopastoral systems combine woody perennials and pastoralism and ... -
Effects of plant-plant interactions on the performance and abundance of Campanula uniflora in Dovre, Norway
(Master thesis, 2021)Anthropogenic environmental changes cause direct and indirect negative effects on alpine ecosystems. Human activities are accelerating the greenhouse effect and fragmenting and changing habitats. Increased temperature has ... -
Effects of plastic additives on precision cut liver slices (PCLS) from Atlantic cod (Gadus morhua)
(Master thesis, 2019)A vast amount of the plastic we use end up in the ocean and estimates suggest a doubling of plastic in the ocean, to 250 million tonnes by 2025. Plastic contain additives such as phthalates, and these are known to have ... -
The effects of precipitation on parental food provisioning in the barn owls (Tyto alba) breeding in Norfolk, UK
(Master thesis, 2021)Even though scientists have extensively studied the barn owl (Tyto alba), there is limited information on how climatic conditions influence parental food provisioning in barn owls on a local scale. Worsened climatic ... -
Effects of repeated captures on Svalbard reindeer (Rangifer tarandus platyrhyunchus) : implications for animal welfare and scientific bias
(Master thesis, 2021)Capturing and marking animals is an essential component of wildlife research. However, data gathered using invasive methods may lead to scientific bias and compromise animal welfare. It is therefore important to evaluate ... -
Effects of resource availability on Arctic fox (Vulpes lagopus) offspring sex ratios
(Master thesis, 2022)The sex ratio of animals at birth has long been a topic of genetic, evolutionary, and biological interest. In polygynous species, mothers in good condition are typically expected to produce more males, while mothers in ... -
Effects of rotational grazing intensity on the quantity and quality of soil organic carbon in Inner Mongolian grasslands
(Master thesis, 2021)The aim of this thesis is to assess the effects of rotational grazing at varying grazing intensity on soil organic carbon (SOC) quantity and quality in Inner Mongolia. People of the autonomous region of Inner Mongolia, ... -
Effects of selective logging on Amazonian wildlife
(PhD thesis;2023:6, Doctoral thesis, 2023)Selective logging of tropical forests is rapidly expanding, making it inevitable that future tropical landscapes will be dominated by production forests. Any biodiversity conservation strategy must consider the potential ... -
Effects of size and forest structure of old-growth forests on the species richness of saproxylic insects
(Master thesis, 2016-02-18)Many saproxylic insects are threatened by extinction, and a decline in the saproxylic species has been observed since the 1800s. The loss of areas of old-growth forest, fragmentation and the decline in volume of dead wood ... -
Effects of snowmelt timing, temperature, and soil moisture on flowering phenology and seed set of Dryas octopetala
(Master thesis, 2023)Climate change advances the timing of life-cycle events (i.e., phenology) in plants, especially in cold biomes where the temperatures have increased twice as fast as in other biomes. In cold biomes, warmer temperatures ... -
Effects of spatio-temporal weather conditions in autumn and winter on body mass and behaviour of the high Arctic Svalbard reindeer (Rangifer tarandus platyrhynchus)
(Master thesis, 2018)There exists large consensus within the research community that climatic changes have a world-wide impact on ecosystems, which is further expected to be most prominent in the Arctic. In these strongly seasonal environments, ... -
Effects of stand structure and stand density on volume growth and ingrowth in selectively cut stands in Norway
(Master thesis, 2021)This thesis studied the effect of stand density on ingrowth, mortality, and volume increment in selectively cut stands in Norway. The effects of stand structure on growth were also addressed by determining the size-growth ... -
Effects of termites (Macrotermes) and large Herbivores on exotic and native tre species in Lake Mburo National Park, Uganda
(Master thesis, 2014-08-21)Both termites and large herbivores are important to ecological processes in the African savannah. Termites and large herbivores contribute to spatial heterogeneity in distinct ways. Large herbivores facilitate tree ... -
Effects of the introduction of Lake Trout (Salvelinus Namaycush) on the Osprey (Pandion Haliaetus) population in Yellowstone National Park
(Master thesis, 2011-03-03)In recent years the number and reproduction of ospreys (Pandion haliaetus) nesting on Yellowstone Lake in Yellowstone National Park (YNP), USA, has been declining. The main hypothesis is that the decline in nesting ospreys ... -
Effects of weather on summer and winter activity level of the high arctic ungulate Svalbard reindeer (Rangifer tarandus platyrhynchus)
(Master thesis, 2015-08-03)Animals are evolutionary adapted to certain weather conditions, but as the climate of the earth is changing many species may face new and significant challenges in their environment. The high-Arctic species Svalbard reindeer ... -
Effekt av grisetangekstrakt (Ascophyllum nodosum) og silisium på rotvekst, næringsstatus og vitalitet ved planting av norsk gran (Picea abies)
(Master thesis, 2021)Norge ligger i det boreale barskogbeltet hvor norsk gran (Picea abies) dominerer og utgjør i underkant av 50 % av den norske skogen. Gjennom norsk lov er det lagt til rette for bærekraftig utnyttelse av skogen som ressurs. ...
