Combining GPS activity measurements and real-time video recordings to quantify the activity budget of wild reindeer (Rangifer tarandus)
(Master thesis, 2016)A resent advancement in the field of movement ecology is the use of GPS activity sensors for the identification of detailed patterns of animal activity. This can potentially yield knowledge about the detailed activity ... -
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 ... -

Great cormorant Phalacrocorax carbo diet related to the supply of marine shallow-living fish species in southeastern Norway; opportunistic or selective foraging?
(Master thesis, 2017)The diet of wintering and nesting great cormorants in a marine, coastal ecosystem located in southeastern Norway was studied by analyzing stomachs of shot individuals and regurgitations collected at a nesting colony. ... -
Impact of fertilization on field vegetation and litter layer in a boreal forest
(Master thesis, 2017)Fertilization of Norwegian boreal forests to increase carbon uptake is suggested as a measure to reduce CO2 emissions. However, studies of the effects of fertilization on field vegetation and litter layer in these forests ... -
Juvenile and subadult survival in Scandinavian wolverines (Gulo gulo) in relation to sex and small rodent abundance
(Master thesis, 2014-08-22)Although the wolverine (Gulo gulo) is regarded as more sensitive to habitat changes and human disturbance than the other large northern carnivores, it is the least investigated one. In Central Norway, fifteen adult female ... -
Naturområder i byen : påvirkning fra tilgrensende boligområder
(Master thesis, 2014-09-26)Grøntområder i byer og tettsteder er viktige for økosystemtjenester som håndtering av overvann, støyreduksjon, bedring av luftkvalitet og folkehelse. De grønne lungene er i dag under et stort press fra utbygging, men også ... -
Predation-induced ungulate carcasses mediate vegetation composition in the boreal ecosystem
(Master thesis, 2017)Apex carnivores are mostly recognized for their effects on ecosystem processes through altering population dynamics and behaviour of their prey. Apex carnivores may also affect lower trophic levels through the distribution ... -
Sea trout (Salmo trutta) area use and harvest selection: different traits lead to different fates
(Master thesis, 2016)The sea trout (Salmo trutta) is a popular target for recreational fishing along the coast. Harvest selection is known to often fish out large individuals in a pop- ulation, selecting for small size and early maturation in ... -
Using Variation in Antler Growth to Identify Short- and Long-Term Energy Allocation Trade-Offs in Female Svalbard Reindeer (Rangifer tarandus platyrhynchus)
(Master thesis, 2017)In environments where resources are limited, trade-offs are made to allocate resources optimally between growth, maintenance, storage and reproduction. Trade-offs can manifest themselves as both short-term processes and ... -
