Ecolocical effects of acute oil spills
(Master thesis, 2011-04-28)The coastal ecosystems are under constant pressure from natural and anthropogenic sources. The interactions between organisms and their environment is a complex myriad of changes and responses making impacts from acute ... -
Ecological implications of road construction in an alum shale bedrock area : a State highway (Rv4) case study
(Master thesis, 2016-08-31)The construction and use of roads and tunnels takes a toll on natural resources and especially the biological integrity of downstream freshwater environments. Consequently, aquatic biota is exposed to elevated levels of a ... -
Ectoparasite (Ceratophyllus vagabundus vagabundus) infestations reduce hatching success in precocial birds (Branta leucopsis) nesting in the High Arctic
(Master thesis, 2016-08-11)Arctic terrestrial ecosystems are ideal systems to study host-parasite interactions because they are sensitive and have fewer confounding interactions than lower latitudes. Since the Arctic is experiencing rapid climate ... -
Effect of exclosure on environment and its socio economic contributions to local people : in the case study of halla exclosure, Tigray, Ethiopia
(Master thesis, 2013-03-22)Though exclosure is sound for degraded land rehabilitation, mainly due to lack of quantitative environmental and socio-economical merits most exclosures are attributed negatively by local people and hence their ... -
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 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 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 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 of a fluctuating climate on the body condition of Atlantic Puffins Fratercula Arctica at Røst, Norway
(Master thesis, 2017)The Atlantic puffin fratercula arctica population is declining in the North Sea- and the Norwegian Sea region. Puffin colonies located in the Røst Archipelago at the outermost tip of the Lofoten Islands, experienced almost ... -
Effects of alien plant species removal on biodiversity and species interactions in two native forest areas on Mauritius
(Master thesis, 2015-11-09)Mauritius Island is one of the world’s most severely ecologically damaged nations, with less than 5% of the original forests remaining as fragments. Yet, it sustains one of the highest tree diversities of all isolated ... -
Effects of anthropogenic disturbance of Afromontane forest on butterflies (Lepidoptera, Nymphalidae) in Amani Nature Reserve, Tanzania.
(Master thesis, 2014-08-01)The majority of the world’s biological diversity is located in the tropics, where forest is an essential biome. A healthy web of biodiversity is the foundation for ecosystem services humans depend on but it is currently ... -
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
