Study of HIPP25, HIPP26, HIPP27 gene expression and glucosinolate content in Arabidopsis thaliana and Noccaea caerulescens upon heavy metal treatments
(Master thesis, 2017)Hyperaccumulator plant species accumulate exceedingly high concentrations of metals in aerial parts and are increasingly studied because of their potential for cleaning up land contaminated with heavy metals. One such ... -
Studying attractiveness and defense responses of Brassica napus transgenic MINELESS plants to insects for pest management
(Master thesis, 2014)Glucosinolate myrosinase system is well-established defense mechanism against insect herbivores feed on plants from Brassicaceae family. This defense mechanism is also known as the mustard oil bomb which bring myrosinase ... -
Studying Behavioral Responses to Bioluminescence in Zooplankton
(Master thesis, 2024)Endringer i det marine lysklimaet kan ha betydelige konsekvenser for biodiversitet og samspillet mellom marine organismer. Denne endringen er spesielt relevant i marine miljøer der bioluminescens, biologisk produsert lys, ... -
Subclinical thiamine deficiency results in failed reproduction in Arctic foxes
(Peer reviewed; Journal article, 2024)Thiamine deficiency can result in life-threatening physiological and neurological complications. While a thiamine-deficient diet may result in the onset of such symptoms, the presence of thiaminase – an enzyme that breaks ... -
Subtle foodscape displacement of a native ungulate by free-ranging livestock in a forest agroecosystem
(Journal article; Peer reviewed, 2018)The prevalence of livestock grazing in wildlife area s is increasing. This transformation of ecosys- tems into agroecosystems is concerning because the intr oduction of new species may cause niche displacement of the ... -
A Successful Crowdsourcing Approach for Bird Sound Classification
(Peer reviewed; Journal article, 2023)Automated recorders are increasingly used in remote sensing of wildlife, yet automated methods of processing the audio remains challenging. Identifying animal sounds with machine learning provides a solution, but optimizing ... -
Successional dynamics in boreal forests: What is the impact of moose browsing, and which pathways are preferred by landowners?
(Master thesis, 2018)Norwegian boreal forests are usually managed for timber production, but also provide other ecosystem services, including game meat, income from hunting licenses, and recreational opportunities. Forest landowners values ... -
Successive Invasion-Mediated Interspecific Hybridizations and Population Structure in the Endangered Cichlid Oreochromis mossambicus
(Journal article; Peer reviewed, 2013-05-09)Hybridization between invasive and native species accounts among the major and pernicious threats to biodiversity. The Mozambique tilapia Oreochromis mossambicus, a widely used freshwater aquaculture species, is especially ... -
Sugar accumulation in leaves of arabidopsis sweet11/sweet12 double mutants enhances priming of the salicylic acid-mediated defense response
(Journal article; Peer reviewed, 2017)In compatible interactions, biotrophic microbial phytopathogens rely on the supply of assimilates by the colonized host tissue. It has been found in rice that phloem localized SWEET sucrose transporters can be reprogrammed ... -
Summary of mire restoration and evaluation of two methods for monitoring mire restoration in Norway
(Master thesis, 2022)Intakte myrer har store karbonlagre, men har i mange tilfeller tidligere blitt drenerte for skogbruk eller landbruk. Derfor ble det igangsatt en plan for restaurering av våtmark av Miljødirektoratet i 2016, med mål om å ... -
Summer and winter MgCO3 levels in the skeletons of Arctic bryozoans
(Peer reviewed; Journal article, 2020)In the Arctic, seasonal patterns in seawater biochemical conditions are shaped by physical, chemical, and biological processes related to the alternation of seasons, i.e. winter polar night and summer midnight sun. In ... -
Supporting Fall Prevention for the Elderly by Using Mobile and Ubiquitous Computing
(Master thesis, 2013)Approximately one third of the elderly (over age 65) fall each year. Falls are the one of the main reasons of injury-related cases and the leading cause of accidental deaths among the elderly. The overwhelming majority of ... -
Survival and cause-specific mortality of harvested willow ptarmigan (Lagopus lagopus) in central Norway
(Journal article; Peer reviewed, 2020)Survival is a key demographic component that often varies as a result of human activities such as recreational harvest. Detailed understanding of seasonal variation in mortality patterns and the role of various risk factors ... -
Survival and growth of farmed, hybrid, and wild salmon during migration in the North Atlantic Ocean
(Master thesis, 2023)Aquaculture has become a significant source of food, surpassing wild fisheries, and contributes to global food security, economic growth, and poverty alleviation. Among various teleost species, Atlantic salmon (Salmo salar ... -
Survival rate and breeding outputs in a high Arctic seabird exposed to legacy persistent organic pollutants and mercury
(Journal article; Peer reviewed, 2015)Chronic exposure to pollutants may represent a threat for wildlife.We tested whether adult survival rate, breeding probability and breeding success the year of sampling and the following year were affected by blood levels ... -
Sustainable management of populations impacted by harvesting and climate change
(Peer reviewed; Journal article, 2022)The sustainable use of natural resources is critical for addressing the global challenges of today. Strategies for sustainable harvesting need to consider not only harvested species, but also other non-harvested species ... -
Sustainable strategies for harvesting predators and prey in a fluctuating environment
(Peer reviewed; Journal article, 2021)The effects of harvest and fluctuating environment on inter-dependent predators and prey are complex and not well-known. We define a stochastic model where the predators and prey dynamically interact. The novelty of the ... -
Sweat responses during inactive recovery after high-intensity running in hot, dry and humid conditions
(Journal article; Peer reviewed, 2019)This study investigated the relationship between high (85%) and low (19%) relative humidity (RH) and sweat rate during inactive recovery after high-intensity work in a hot environment (30 °C). Ten male subjects performed ... -
Swim for it: Effects of simulated fisheries capture on the post-release behaviour of four Great Barrier Reef fishes
(Journal article; Peer reviewed, 2018)After being caught and released by a fishery, some animals may be sufficiently impaired so as to be vulnerable to predators. The duration and severity of post-release impairments have rarely been studied under natural ... -
Sympatric Atlantic puffins and razorbills show contrasting responses to adverse marine conditions during winter foraging within the North Sea
(Journal article; Peer reviewed, 2019)Background: Natural environments are dynamic systems with conditions varying across years. Higher trophic level consumers may respond to changes in the distribution and quality of available prey by moving to locate new ...
