Seasonal fluctuations of rainfall ... -
The influence of arthropods availability on fledgling morphology and reproductive success in wild house sparrows
(Master thesis, 2023)Over hele verden rapporteres det om nedgang i antall innsekter samt fugler i kulturlandskapet. Redusert tilgjengelighet av leddyr har vært foreslått som en mulig årsak til nedgangen av insektspisende fugler gjennom ... -
The influence of human induced factors on African elephant (Loxodonta africana) populations in Sub-Saharan Africa
(Master thesis, 2015)Numerous studies have been done on the conservation of the African elephant (Loxodonta africana) yet too few studies have focused on comparing the ultimate factors that influence the African elephant populations. Here, we ... -
The influence of natural variation and organohalogenated contaminants on physiological parameters in white-tailed eagle (Haliaeetus albicilla) nestlings from Norway
(Journal article; Peer reviewed, 2019)Environmental exposure to organohalogenated contaminants (OHCs), even at low concentrations, may cause detrimental effects on the development and health of wild birds. The present study investigated if environmental exposure ... -
The influence of phosphate depletion on lipid metabolism of microalgae
(Doctoral theses at NTNU;2018:158, Doctoral thesis, 2018)Photosynthetic algae play an essential role in the ocean ecosystem by capturing anthropogenic CO2 and are the primary producers in the food web. Important contribution in the ecosystem has been observed by the phylum of ... -
The interacting effects of forestry and climate change on the demography of a group‑living bird population
(Journal article; Peer reviewed, 2018)Anthropogenic degradation of natural habitats is a global driver of wildlife population declines. Local population responses to such environmental perturbations are generally well understood, but in socially structured ... -
The invasion success and invasiveness of the introduced Rana lessonae and its hybrid associate R. kl. esculenta (Amphibia) in Southwest Norway
(Master thesis, 2011)In 2003, congeners of the green frog complex, R. lessonae and R. kl. esculenta, were intentionally and illegally introduced to Finnøy, an island in Southwest Norway. All freshwater localities on the island were investigated ... -
The Landscape Genomics of the Scandinavian Red Fox
(Master thesis, 2022)Som følge av globale endringer i miljø og arealbruk har man sett endringer i økosystemer og ekspansjon i boreale arter. Landskapsgenomikk er et spirende fagfelt som kombinerer økologi og genetikk. I sammenheng med globale ... -
THE LIFE CYCLE AND HOME RANGE OF ARCTOSA CINEREA FOR TWO LOCALITIES IN TRØNDELAG, NORWAY
(Master thesis, 2023)Arctosa cinerea er en stor edderkoppart i familien Lycosidae. I Norge regnes den som truet og finnes kun ved elvebredder og sandstrender i Trøndelag fylke. Fokus for denne studien var hjemmeområde og livsstadier til A. ... -
The measure and mismeasure of reciprocity in heterostylous flowers
(Journal article; Peer reviewed, 2017)The goal of biological measurement is to capture underlying biological phenomena in numerical form. The reciprocity index applied to heterostylous flowers is meant to measure the degree of correspondence between fertile ... -
The molecular basis of long chain polyunsaturated fatty acid (LC-PUFA) biosynthesis in Atlantic salmon (Salmo salar L): In vivo functions, functional redundancy and transcriptional regulation of LC-PUFA biosynthetic enzymes
(Doctoral theses at NTNU;2019:383, Doctoral thesis, 2019)Farmed Atlantic salmon (Salmo salar L.) is a rich source of the omega-3 fatty acids (ω-3 FA), eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, which are linked to health benefits in humans including prevention of ... -
The Myb like transcription factor Phosphorus Starvation Response (PtPSR) controls conditional P acquisition and remodeling in marine microalgae
(Journal article; Peer reviewed, 2019)Phosphorus (P) is one of the limiting macronutrients for algal growth in marine environments. Microalgae have developed adaption mechanisms to P limitation that involve remodelling of internal phosphate resources and ... -
The Norwegian Cognitive impairment after stroke study (Nor-COAST): study protocol of a multicentre, prospective cohort study
(Journal article; Peer reviewed, 2018)Background Early and late onset post-stroke cognitive impairment (PCI) contributes substantially to disability following stroke, and is a high priority within stroke research. The aetiology for PCI is complex and related ... -
The parasite Syngamus trachea in a metapopulation of house sparrows
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:178, Doctoral thesis, 2014)Understanding the effects of parasites on population dynamics of hosts is an important, and often neglected, part of population ecology. In this thesis I first investigate the spatio-temporal distribution of the parasite ... -
The park-people conflict in the Chitwan National Park with reference to the Asiatic one-horned rhinoceros (Rhinoceros unicornis)
(Master thesis, 2012)The lack of access to forest resources for the rural community residing in the buffer zones of national parks has created conflict between the national parks, the people residing in these areas and wildlife. People residing ... -
