Effects of anthropogenic disturbances on ground beetle (Coleoptera, Carabidae) communities in Afromontane forests: a comparison between habitats with different levels of disturbance in Amani Nature Reserve, Tanzania.
(Master thesis, 2014-08-05)The family of ground beetles (Coleoptera, Carabidae) is one of the most species-rich coleopteran families. Ground beetles are good indicators of habitat disturbances, and could provide valuable information for sustainable ... -
Effects of charcoal addition on spring wheat : a greenhouse study
(Master thesis, 2012-09-10)Abstract: In this thesis I have investigated if addition of charcoal to the soil improves the growth and yield of spring wheat. My thesis is based on an experimental greenhouse study in which different amounts of charcoal ... -
Effects of climate change on alpine plant species at Finse, Southern Norway
(Master thesis, 2012-09-07)The issue of climate change is one of the most discussed topics on Earth. The Earth is warming up and that is expected to continue in future. Alpine vegetation has already been affected by climate warming and has already ... -
Effects of culling on the pelagic whitefish population in Lake Randsfjorden aiming at establishing a commercial fishery
(Master thesis, 2015-08-05)The fishery in Lake Randsfjorden has long traditions, and especially the European whitefish Coregonus lavaretus has earlier played an important role as additional food supply for local communities in the area. After a rapid ... -
Effects of disturbance on biological diversity of beetles (Coleoptera) in the field layer: a comparison between power-line corridors and closed-canopy forests.
(Master thesis, 2012-09-07)Since the start of industrial forestry in the 1700 century Norwegian boreal forests have gone true a dramatic change. Modern forestry practices have made the forests more homogenous, due to clear cutting of old forest, ... -
Effects of fire history on species richness and carbon stocks in a Peruvian puna grassland, and development of allometric equations for biomass estimation of common puna species
(Master thesis, 2011-09-09)High-elevation ecosystems have recently received increasing attention from the carbon financing sector. This has sparked the need for reliable and non-destructive methods to estimate carbon stocks in these ecosystems. The ... -
Effects of forest fire on production of down woody debris in Aust-Agder County in Norway
(Master thesis, 2011-10-07)Forest fires have played an important role in structuring the boreal conifer forest. Forest fires produce dead wood, which is important for biodiversity. Many species, including Red List species, are dependent on dead wood ... -
Effects of forestry, predators and weather on capercaillie (Tetrao urogallus) and black grouse (Lyrurus tetrix) in South-East Norway
(Master thesis, 2017)The European populations of capercaillie (Tetrao urogallus) and black grouse (Lyrurus tetrix) have declined the last 50 to 100 years. The decline has happened at the same time as changes in forestry practices, predation ... -
Effects of hunting on primate populations in Pacaya-Samiria National Reserve, Peru
(Master thesis, 2017)De viktigste makrohabitatene av skog som finnes i Amasonas bassenget er terra firme skoger som ikke blir oversvømt og sesongmessig oversvømte várzea skoger. Disse skogene huser ulike ansamlinger av flora og fauna, som ... -
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 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 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 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 ... -
