Factors affecting hyrax presence/absence and population size
(Master thesis, 2015)Understanding the factors influencing whether a species is present or absent in an ecosystem and how these factors affect their population size is crucial for conservation initiatives. There are two species of hyraxes in ... -
Factors Affecting Juvenile Movement in a House Sparrow Metapopulation
(Master thesis, 2012)Dispersal propensity can vary considerably between individuals in a population. Understanding which individuals disperse- and under what circumstances these individuals disperse is valuable for conservation. Factors ... -
FACTORS AFFECTING THE ATTITUDES OF THE LOCAL INHABITANTS OF THE KONDOA DISTRICT-TANZANIA, TOWARD THE RED-BILLED QUELEA (Quelea quelea)
(Master thesis, 2013)Interactions between humans and the red-billed queleas in the Kondoa District have shaped the attitudes of the local inhabitants toward these birds. This bird is considered a pest of small grain cereal crops, which represent ... -
Factors Influencing African Wild Dog (Lycaon pictus) Habitat Selection and Ranging Behaviour: Conservation and Management Implications
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:54, Doctoral thesis, 2014)Large carnivores are particularly susceptible to negative anthropogenic effects. As human populations continue to encroach on wildlife habitats, protected areas may become increasingly important for large carnivore ... -
Factors influencing local communities’ attitudes toward protected areas: A comparative study of five different PAs in Myanmar
(Master thesis, 2022)Abstract Protected areas (PAs) are one of the most effective mitigation strategies to reduce anthropogenic pressures on biodiversity and natural resources. However, the rights and involvements of local communities living ... -
Factors influencing return rate and marine residence durationin sea trout populations in Central Norway
(Peer reviewed; Journal article, 2021)Brown trout (Salmo trutta) display extensive plasticity in marine migratory behaviours, with marine migrations considered to be an adaptive strategy which enables sea trout to maximize growth and reproductive potential. ... -
Factors Influencing Sea Trout (Salmo trutta) Migration Dynamics in Western Norway
(Master thesis, 2022)Anadrom brunørret eller sjøørret (Salmo trutta) vandrer til sjøen for å maksimere dens vekst på grunn av bedre næringstilgang i marine habitater. Hvor lenge fisken er i sjøen og tidspunktet for vandring er påvirket av en ... -
Factors influencing the habitat suitability of wild Asian elephants and their implications for human–elephant conflict in Myanmar
(Peer reviewed; Journal article, 2023)Anthropogenic disturbances are key factors affecting the distribution and ranging behaviour of wild elephants. Such disturbances exaggerate threats to the survival and population decline of wild elephants, and they have ... -
FACTORS REGULATING THE RETURN MIGRATION OF SEA TROUT (SALMO TRUTTA) IN RIVER FREMSTADELVA
(Master thesis, 2021)Til tross for at luseinfestasjoner på vill Atlantisk laks (Salmo salar) i dag brukes som en bærekrafts indikator i det norske forvaltnings systemet, Trafikklyssystemet, behøves mer kunnskap om ørretens vandringsatferd samt ... -
Family planning in the high Arctic: earlier spring onset advances age at first successful reproduction in barnacle geese
(Master thesis, 2018)I en verden under oppvarming der arter møter nye miljøforandringer er evalueringen av klimaeffekter på individnivå gjennom livshistorie egenskaper viktig for å forstå langtids- utsiktene til naturlige populasjoner. ... -
Farmed cod escapees and net-pen spawning left no clear genetic footprint in the local wild cod population.
(Journal article; Peer reviewed, 2015-11-18)This study investigated a potential genetic introgression from farmed to wild cod Gadus morhua L. in the Trondheimsfjord, Norway. During the first 2 yr of operation of a cod farm in the inner part of the fjord, 2 large ... -
Farming of juvenile Lumpfish (Cyclopterus lumpus). Growth pattern, anesthetic protocol, and salinity tolerance.
(Master thesis, 2016)Sea lice (Lepeophtheirus salmonis) infestation is currently one of the biggest challenges within the Norwegian Atlantic salmon (Salmo salar) industry, causing major expenses and limiting further production growth. Traditional ... -
Fast currents reduce production performance of post-smolt Atlantic salmon.
(Journal article; Peer reviewed, 2015)In the future, an increasing number of salmon farms may be located in areas with fast water current velocity due to limited availability of more sheltered locations. However, there is little information as to how fast ... -
Fate and transport of forever chemicals in the aquatic environment: Partitioning and biotransformation of mixtures of Per- and Polyfluoroalkyl Substances (PFAS) from different point sources and resulting concentrations in biota
(Doctoral theses at NTNU;2021:89, Doctoral thesis, 2021)Fate and transport of forever chemicals in the aquatic environment Per- and polyfluorinated alkyl substances (PFAS) are anthropogenic organic pollutants, defined as aliphatic substances that contain at least one ... -
Fate of Lepeophtheirus salmonis and Caligus elongatus During Farmed Salmon Crowding
(Master thesis, 2021)Økt reproduksjon og spredning av Lepeophtheirus salmonis og Caligus elongatus hindrer videre vekst i oppdrettsnæringen og truer den naturlige bestanden av villaks. Trenging vil si å øke tettheten av fisken og er en viktig ... -
The fate of poly- and perfluoroalkyl substances in a marine food web influenced by land-based sources in the Norwegian Arctic
(Peer reviewed; Journal article, 2021)Although poly- and perfluorinated alkyl substances (PFAS) are ubiquitous in the Arctic, their sources and fate in Arctic marine environments remain unclear. Herein, abiotic media (water, snow, and sediment) and biotic media ... -
