Feather corticosterone in Northern Bald Ibis Geronticus eremita: a stable matrix over time able to predict reproductive success
(Peer reviewed; Journal article, 2020)Measuring corticosterone concentrations in feathers (FCC) has been increasingly used as an integrated index of bird’s response to stressors, ofering valuable insights into subsequent carry-over efects. However, it is still ... -
Feathers as an integrated measure of organohalogen contamination, dietary tracers and stress in Goshawk (Accipiter gentilis) nestlings from Trøndelag, Norway
(Master thesis, 2015)Because of their high sensitivity and wide distribution, predatory birds have proven useful as sentinel species for monitoring exposure of organohalogen contaminants (OHCs). Nestling feathers have been evaluated as valid ... -
Feathers as an integrated measure of organohalogen contamination, its dietary sources and corticosterone in nestlings of a terrestrial bird of prey, the northern Goshawk (Accipiter gentilis)
(Peer reviewed; Journal article, 2022)In this study, we evaluated the suitability of body feathers, preen oil and plasma for estimation of organohalogen compound (OHC) exposure in northern goshawk Accipiter gentilis nestlings (n = 37; 14 nests). In addition, ... -
Feeding ecology and behavior of nudibranchs from the sublittoral zones of Trondheimsfjorden and interactions with fouling communities
(Master thesis, 2022)Stormaneter eller medusa i klassen Scyphozoa opptrer som en plage for fiskevelferd i akvakulturmerder, for rekreasjonsverdien i kystnære områder, og ovenfor deres eget rykte. Deres bentiske polyppstadie forårsaker ... -
Feeding of turnip root fly (Delia floralis) and cabbage root fly (Delia radicum) larvae on Brassica napus L. transgenic MINELESS plants – Effects on insect development
(Journal article, 2014)The dual component glucosinolate-myrosinase defence system is present in plants of the Brassicaceae. Upon insect attack, the defence system gets activated and forms glucosinolate hydrolysis products, which affect insect ... -
Feeding type and development drive the ingestion of microplastics by freshwater invertebrates
(Journal article; Peer reviewed, 2017)Microscopic plastic items (microplastics) are ubiquitously present in aquatic ecosystems. With decreasing size their availability and potential to accumulate throughout food webs increase. However, little is known on the ... -
Female advantage? Investigating female frequency and establishment performance in high-arctic silene acaulis
(Peer reviewed; Journal article, 2019)Many Arctic plants overcome limited time budgets and energy budgets by selfing, increasing the risk of inbreeding. Gynodioecious breeding systems allows for selfing by hermaphrodites, whereas enforced outcrossing through ... -
Finding gene regulatory network candidates using the gene expression knowledge base
(Journal article; Peer reviewed, 2014)Background: Network-based approaches for the analysis of large-scale genomics data have become well established. Biological networks provide a knowledge scaffold against which the patterns and dynamics of ?omics? data can ... -
Finding the needle in the haystack: Comparison of methods for salmon louse enumeration in plankton samples
(Peer reviewed; Journal article, 2021)The economic and social implications of salmon louse (Lepeophtheirus salmonis) epidemics in salmon aquaculture drive focus of the dispersal dynamics of the planktonic larval stages. The vast spatial scale and high connectivity ... -
Fine-scale dynamics and community stability in boreal peatlands: revisiting a fen and a bog in Sweden after 50 years
(Journal article; Peer reviewed, 2014)Multi‐decadal studies of community and ecosystem dynamics are rare; however, this time frame is most relevant for assessing the impact of anthropogenic influences and climate change on ecosystems. For this reason, we ... -
Finmotorisk isometrisk kraftkontroll i hånd og fingre ved nedkjøling
(Master thesis, 2017)Background: People with outdoor occupations will large parts of the year be exposed to low ambient temperatures. Prolonged exposure to low temperatures can impair performance in several ways, such as reduced muscle function ... -
Fire regulates the abundance of alien plant species around roads and settlements in the Serengeti National Park
(Journal article; Peer reviewed, 2018)A large portion of East African ecosystems are officially protected, yet increasing wildlife tourism and infrastructural development are exposing these areas to invasion by alien plant species. To date there has been little ... -
First biogeographical survey of Artemia in Tanzania
(Journal article; Peer reviewed, 2018)In an Artemia survey conducted along the coast of Tanzania between March and July 2017, 32 salt pans in Tanga, Dar es salaam, Pwani, Lindi, and Mtwara were assessed. Of all visited salt pans, 16 (50%) had either Artemia ... -
First evaluation of the use of down feathers for monitoring persistent organic pollutants and organophosphate ester flame retardants: A pilot study using nestlings of the endangered cinereous vulture (Aegypius monachus)
(Journal article; Peer reviewed, 2018)Raptor feathers have been increasingly used to assess pollutants in ecotoxicological monitoring studies. However, the suitability of down feathers to detect pollutants has not yet been investigated. In this study, ... -
First feed matters: The first diet of larval fish programmes growth, survival, and metabolism of larval ballan wrasse (Labrus bergylta)
(Peer reviewed; Journal article, 2022)The use of cleaner fish, such as the ballan wrasse (Labrus bergylta), is important for combatting the sea lice problem in salmonid cage farming. Ballan wrasse is the only wrasse species that is cultivated, though only about ... -
First hyperspectral imaging survey of the deep seafloor: High-resolution mapping of manganese nodules
(Journal article; Peer reviewed, 2018)Hyperspectral seafloor surveys using airborne or spaceborne sensors are generally limited to shallow coastal areas, due to the requirement for target illumination by sunlight. Deeper marine environments devoid of sunlight ... -
First record of Common Tailorbird (Orthotomus sutorius) parasitism by Plaintive Cuckoo (Cacomantis merulinus) in Bangladesh
(Peer reviewed; Journal article, 2016)The Plaintive Cuckoo (Cacomantis merulinus) is a widespread brood parasite in Asia, but no data on host species utilization in Bangladesh exist. By searching for nests of all possible host species of the Plaintive Cuckoo ... -
First-time Migration in Juvenile Common Cuckoos Documented by Satellite Tracking
(Journal article; Peer reviewed, 2016)Being an obligate parasite, juvenile common cuckoos Cuculus canorus are thought to reach their African wintering grounds from Palearctic breeding grounds without guidance from experienced conspecifics but this has not been ... -
