The role of rural education programs on Conservation Biology - Unravelling and possibly affect the understanding of ecosystem services and attitudes toward nature amongst people living in the Serengeti-Mara ecosystem
(Master thesis, 2018)Today, human-induced impacts like climate change, human population growth and land use change are negatively affecting the biodiversity and ecosystems, which are important for human well-being. Africa is amongst the places ... -
The Role of the Arctic Fox in the Breeding Success of the Snow Bunting
(Master thesis, 2022)The reproductive success of breeding birds can be determined by many different factors. One factor often associated with the failure of a brood is nest depredation. To avoid depredation, different bird species implement ... -
The role of the copepod Calanus finmarchicus in affecting the fate of marine oil spills
(Doctoral thesis at NTNU;2015:304, Doctoral thesis, 2015)Background: Oil spills in marine environments are subject to biological, physical and chemical weathering processes, including entrainment of oil as droplets in the water column. The oil droplets with diameter < 100 μm ... -
The role of two zinc finger protein transcription factors in Arabidopsis thaliana cell wall integrity maintenance
(Master thesis, 2022)Alle planteceller er omringet av en kompleks struktur av polysakkarider og proteiner som kalles for celleveggen. I tillegg til å sørge for mekanisk støtte, virker celleveggen som en barriere mellom plantecellen og dens ... -
The Role of Wildlife Education in Conservation Biology: Can awareness change Locals` Attitudes towards the Endangered African Wild Dog (Lycaon pictus) ?
(Master thesis, 2013)In this master thesis, I will concentrate on the increasing interest for the research field of conservation biology, and what it can do to contribute to turn the future development in a more sustainable direction for a ... -
The socio-ecological impacts of the invasive house crow (Corvus splendes) in Tanzania
(Master thesis, 2023)Invasjonsarter er en av de største truslene for biologisk mangfold i naturen i dag. Lokal kunnskap og holdninger til invasjonsarter kan bidra til å forstå hvilken påvirkning de har på miljøet. Ved å avdekke allmennhetens ... -
The stress hormone corticosterone in a marine top predatorreflects short-term changes in food availability
(Journal article; Peer reviewed, 2015)In many seabird studies, single annual proxies of prey abundance have been used to explain variability in breeding performance, but much more important is probably the timing of prey availability relative to the breeding ... -
The stress of being contaminated? Adrenocortical function and reproduction in relation to persistent organic pollutants in female black legged kittiwakes
(Journal article; Peer reviewed, 2014)High levels of environmental pollutants such as persistent organic pollutants (POPs) including PCB and DDT have been found in the Arctic and many of those pollutants may impair reproduction through endocrine disruption. ... -
The Svalbard reindeer (Rangifer tarandusplatyrhynchus) and its food base: plant-herbivoreinteractions in a high-arcticecosystem
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:17, Doctoral thesis, 2008)One challenge in ecology is to predict long-term effects of high herbivore densities on the vegetation, and its feedback consequences. I examined plant-herbivore dynamics during a 26-year period following reintroduction ... -
The Tautra Cold-Water Coral Reef - Mapping and describing the biodiversity of a cold-water coral reef ecosystem in the Trondheimsfjord by use of multi-beam echo sounding and video mounted on a remotely operated vehicle
(Master thesis, 2016)The Tautra sill is one of three sill dividing Norway s third largest fjord, the Trondheimsfjord. Knowledge of cold-water corals in the fjord has been known for centuries and has been a popular object of interest in regards ... -
The usability of eDNA to identify and quantify zooplankton communities
(Master thesis, 2023)Havet vårt står midt i en trippel planetarisk krise. Klimaendringer, forurensning og tap av biologisk mangfold påvirker både habitater og de som bor der. Havovervåkingsprogrammer er viktige siden de gir data som kan bidra ... -
The use of light, restrictive feeding, fibrous feed and stocking density and the consequences for animal welfare for poultry species kept in Norway - Scientific Opinion of the Panel on Animal Health and Welfare of the Norwegian Scientific Committee for Food and Environment
(Peer reviewed; Journal article, 2022) -
The utilization of frass from the yellow mealworm (Tenebrio molitor) as a plant fertilizer and immune stimulant
(Master thesis, 2021)Produksjon av insekt er en hurtigvoksende industri verden over, siden insekter kan oppsirkulere matavfall til en bærekraftig proteinkilde som kan brukes både som menneskemat og som dyrefôr. Det mest omfangsrike biproduktet ... -
The β-oxidation pathway is downregulated during diapause termination in Calanus copepods
(Journal article; Peer reviewed, 2019)Calanus copepods are keystone species in marine ecosystems, mainly due to their high lipid content, which is a nutritious food source for e.g. juvenile fish. Accumulated lipids are catabolized to meet energy requirements ... -
Therapeutic effect of a Chlamydia pecorum recombinant major outer membrane protein vaccine on ocular disease in koalas (Phascolarctos cinereus)
(Journal article; Peer reviewed, 2019)Chlamydia pecorum is responsible for causing ocular infection and disease which can lead to blindness in koalas (Phascolarctos cinereus). Antibiotics are the current treatment for chlamydial infection and disease in koalas, ... -
There is more to climate than the North Atlantic Oscillation: a new perspective from climate dynamics to explain the variability in population growth rates of a long-lived seabird
(Journal article; Peer reviewed, 2015)Predicting the impact of global climat echange on the biosphere has become one of the most important efforts in ecology. Ecosystems worldwide are changing rapidly as a consequence of global warming, yet our understanding ... -
Thermal performance in zebrafish (Danio rerio) - Thermal acclimation capacity in wild and domesticated zebrafish
(Master thesis, 2018)In times of imminent threat of climate change, clear evidence of which physiological mechanisms are limiting thermal performance remains scarce. This thesis involved measuring different performances, over a wide range of ... -
