The transfer of radiocesium in coastal waters : radiocesium tracer to investigate mixing zone processes in brackish waters
(Master thesis, 2019)In the event of a reactor accident, debris plumes containing artificially produced radionuclides could impose a great risk for the environment in distances far from the accident site. Radionuclides can enter the marine ... -
The use of animal-borne video systems to study foraging ecology and diel behaviour : a review and case study on the Scandinavian brown bear (Ursus arctos)
(Master thesis, 2019)Animal-borne video systems, also known as Crittercams, were developed by Greg Marshall in the 1980s to capture video footage from the animal’s perspective. Primarily deployed on marine species, such as attached to the ... -
The use of camera traps to identify seed removal agents in an East African savanna
(Master thesis, 2017)Camera traps are commonly used to capture vertebrate activity, but remote video recording of invertebrates may now be possible due to new technology. Video motion detection (VMD) technology can be used to record large ... -
Thermoregulatory behavior in a warming Arctic : bed site selection by Svalbard reindeer (Rangifer tarandus platyrhynchus) in summer
(Master thesis, 2018)Climate change leads to rapidly increasing mean temperatures, and the climate warming is particularly pronounced in the Arctic. In Arctic mammals with long generation times, evolution of physiological and morphological ... -
Tilbud av norsk vannkraft - En økonometrisk analyse av hvordan ulike faktorer påvirker nasjonalt og regionalt tilbud av regulerbar vannkraft
(Master thesis, 2014-08-05)Denne masteroppgaven analyserer hvordan det nasjonale og regionale tilbudet av regulerbar vannkraft, påvirkes av faktorer som inngår i produsentenes vannverdiberegninger. Dette gjøres ved å analysere den regulerbare ... -
Tilvekst på bestands- og enkelttrenivå ti år etter selektiv hogst etter KONTUS- prinsippet
(Master thesis, 2015-08-06)I årene frem mot årtusenskiftet var det en økende interesse for selektive hogster i Europa, og også her i Norge. I den forbindelse ble KONTUS-prosjektet startet, for å øke kunnskapen og interessen rundt selektive hogster. ... -
Tilvekstreaksjoner på enkelttrenivå hos gran og furu etter tynning
(Master thesis, 2021)Tynning reduserer konkurransen i et bestand og øker tilveksten hos de gjenværende trærne. Flere studier har undersøkt tynningsreaksjoner på enkelttrenivå og vist en større absolutt tynningsreaksjon hos større trær sammenliknet ... -
Tilvekstrespons på tynning i svartor (Alnus glutinosa (L.) Gaertn) over en sytten-års periode
(Master thesis, 2015-08-04)Svartor (Alnus glutinosa (L.) Gaertn.) er et relativt ubeskrevet treslag i den norske produksjonsforskningen. Det meste av forskningen er blitt gjort i Sverige eller Sentral‐Europa. Formålet med denne studien var å ... -
Timeliness in seedbed preparation for spring cereals : studies to prepare for climate change in Norway
(PhD Thesis;2019:13, Doctoral thesis, 2019)Future increases in winter and spring precipitation in Norway may exacerbate the dilemma of spring fieldwork that farmers have, concerning topsoil compaction versus delayed sowing on autumn-ploughed soil. Both topsoil ... -
Tiurens (Tetrao urogallus) habitatbruk og atferd på dagtid under leikperioden
(Master thesis, 2010-12-06)Ved hjelp av GPS-teknologi studerte vi områdebruk og atferd til tiur (Tetrao urogallus) på dagtid under leikperioden (20. april-31. mai 2009). Dette er første gang tiurer har blitt utstyrt med GPS-sendere, noe som ga oss ... -
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 ... -
