To ban or not to ban? : spatial and temporal effects of banning long-term supplementary feeding on red deer space use, forest browsing damage and the performance and nitrogen content of bilberry plants
(Master thesis, 2020)Supplementary feeding (i.e. diversionary feeding) of red deer (Cervus elaphus) and other cervids is a widespread tool in wildlife management in Europe and North America. In 2016 supplementary feeding was banned in Norway ... -
To migrate or not to migrate - that`s the question : why do rudd (Scardinius erythrophthalmus) in the Storelva system migrate to Sandnesfjorden?
(Master thesis, 2013-09-05)Migration is a common behaviour in many species and the duration and migration distance vary among species. The occurrence of migration has been related to a gain in fitness through feeding, refuge and spawning benefits, ... -
Tortricid pests (Lepidoptera: Tortricidae) in apple orchards of South-Eastern Norway surveyed by pheromone-baited traps
(Master thesis, 2020)The trend of minimizing pesticide usage in agriculture leads scientists to think about alternatives of how pest numbers can be reduced. The tortricid moths (Lepidoptera: Tortricidae) is a group of insects responsible for ... -
Tourism megatrends : a literature review focused on nature-based tourism
(MINA fagrapport;42, Report, 2017)This report identifies and describes the most prominent exogenous factors affecting nature-based tourism (NBT). Megatrends and associated sub-trends were identified by means of a literature review and structured using the ... -
Tourists perception of Recreational Oppertunity Spectrum as a management tool in Fulufjället National Park
(Master thesis, 2015-08-10)At a time where the amount of wilderness is critically declining, while the demand for nature experiences are rising, multi orientated management becomes increasingly important. One management tool for visitor planning is ... -
The toxicity of depleted uranium and uranium nanoparticles in the nematode Caenorhabditis elegans
(Master thesis, 2020)In recent years, nanoparticles have been the subject of intensive research and have been shown to have unique toxic properties compared to bulk material. Nevertheless their toxic mechanisms, and thus their ecotoxicological ... -
Toxicity of single biocides and their mixtures in the algae Chlamydomonas reinhardtii
(PhD Thesis;2015:69, Doctoral thesis, 2017-07-12)Aquatic organisms are exposed to several organic compounds including biocides. These compounds are widely used, for instance as disinfectants, in antifouling paints, or as material preservatives. Biocides can originate ... -
Trace metal availability in soils under different land uses of the Danube basin in Croatia
(PhD Thesis;2011:65, Doctoral thesis, 2011)Soils are non-renewable resource of biological, chemical and physical properties. One of the ecological functions of the soil is its capacity to filter and buffer trace metals. Trace metals can pose a threat on the one ... -
Trace metal speciation and uptake in Atlantic salmon (Salmo salar) in coastal water
(Master thesis, 2020)Estuarine environments have a high risk of metal pollution due to the influx from rivers. Freshwater from rivers mixed with seawater in coastal areas gives varied and complex water chemistry. In the estuarine environment ... -
Trace metals in water and fish (Unga species, Pungu maclareni, catfish Clarias maclareni) from Lake Barombi Mbo, Cameroon
(Master thesis, 2012-09-17)Lake Barombi Mbo is an isolated oligotrophic lake situated in the volcanic range of West Cameroon and home to several endangered endemic cichlids. A fieldwork was carried out at the lake where water and fish samples ... -
Traditional healers as a foundation pillar of medicinal plant conservation in Uganda.
(Master thesis, 2012-09-12)Traditional knowledge (TK) and medicinal plants (MPs) play an important role in Uganda and in Africa in general. It has been estimated that nearly 80% of the population relies on MPs. It is also believed that traditional ... -
Transfer of river-discharged Cs-137 in estuaries : a case study from Vefsna river and the Vefsnfjord in Nordland, Norway
(Master thesis, 2021)Several decades after the Chernobyl accident, it is still detectable activities of Cs-137 in the environment. Norway was highly affected by radioactive fallout, where one of the locations that received the highest doses ... -
Transfer of strontium in the potato plant, solanum tuberosum L., following single foliar wet deposition : field experiments performed in Eastern Norway and at the West Coast of Norway
(Master thesis, 2020)90Sr is one of the most important and frequent radioactive products from nuclear fission. If ingested, it is considered a major hazard to humans due to high retention in skeleton, leading to irradiation of cells and cancer ... -
Transport av næringsstoffer og humus til Lundebyvannet i Eidsberg kommune
(MINA fagrapport;55, Report, 2019)Lundebyvannet i Eidsberg kommune oppfyller ikke krav om minst god økologisk status, særlig pga. en veldig høy konsentrasjon av algen Gonyostomum semen. Ifølge våre undersøkelser i Lundebyvannet utfører Gonyostomum semen ... -
Transportledetider : en kartlegging av variasjon og årsaker
(Master thesis, 2021)For at sagbruk og industri skal ha tilgang til virke er de avhengige av at skognæringen har et jevnt avvirkningskvantum gjennom året, i tillegg til at man ønsker en jevn flyt av tømmer til nasjonal og internasjonal industri. ... -
Tredjegrads energikjedeanalyse av hydrogenbiler
(Master thesis, 2022)Norge har som mål om å redusere utslippet av klimagasser med minst 50% i 2030 sammenlignet med utslippsnivået i 1990 (Miljøstatus, 2021b). Utslippet fra veitrafikken utgjør ca. 17% av utslippene i Norge i dag (Miljøstatus, ... -
