Feasibility of active handheld NDVI sensors for monitoring of lichen ground cover
(Peer reviewed; Journal article, 2023)Vegetation indices are corner stones in vegetation monitoring. However, previous field studies on lichens and NDVI have been based on passive sensors. Active handheld sensors, with their own light sources, enables high- ... -
Feasibility of hyperspectral vegetation indices for the detection of chlorophyll concentration in three high Arctic plants: Salix polaris, Bistorta vivipara, and Dryas octopetala
(Peer reviewed; Journal article, 2018)Remote sensing, which is based on a reflected electromagnetic spectrum, offers a wide range of research methods. It allows for the identification of plant properties, e.g., chlorophyll, but a registered signal not only ... -
Feather Corticosterone Levels on Wintering GroundsHave No Carry-Over Effects on Breeding among ThreePopulations of Great Skuas (Stercorarius skua)
(Peer reviewed; Journal article, 2014)Environmental conditions encountered by migratory seabirds in their wintering areas can shape their fitness. However, the underlying physiological mechanisms remain largely unknown as birds are relatively inaccessible ... -
Fecundity and water flow influence the dynamics of Atlantic salmon
(Journal article; Peer reviewed, 2016)Populations are retained at reduced levels by resource competition and environmental stochasticity. In the Norwegian River Imsa, the relationship between fecundity of Atlantic salmon (Salmo salar) spawners and number of ... -
Female sociality and kin discrimination in brood parasitism: Unrelated females fight over egg laying
(Peer reviewed; Journal article, 2015)In conspecific brood parasitism, some females (“parasites”) lay eggs in nests of other females of the same species (“hosts”). This reproductive tactic is particularly common in waterfowl, in which studies suggest that ... -
Femti år etter utsettingene av mysis (Mysis relicta) og firetornet istidskreps (Pallasiola quadrispinosa) i norske innsjøer: til gagn eller skade?
(Peer reviewed; Journal article, 2022)Krepsdyra Mysis relicta (mysis, pungreke) og Pallasiola quadrispinosa (firetornet istidskreps, heretter kalt pallasea) forekommer i Norge naturlig i noen innsjøer på Østlandet. Etter utsettinger i regulerte innsjøer i ... -
Fibre caps across Europe: type studies and 11 new species of Inocybe (Agaricales, Basidiomycota)
(Peer reviewed; Journal article, 2022)Based on detailed morphological and genetic investigation, 11 new species of Inocybe (I. abdita, I. alcis, I. carissima, I. cryptica, I. culicis, I. mecoana, I. mortenii, I. orioli, I. rangiferi, I. sepiana and I. turfae) ... -
Field spectroscopy data from non-arable, grassdominated objects in an intensively used agricultural landscape in East Anglia, UK

Fine-scale behavioural differences distinguish resource use by ecomorphs in a closed ecosystem
(Journal article, 2016)Temporal differences in habitat use and foraging specialisms between ecomorphs represent aspects of behavioural phenotype that are poorly understood with regard to the origin and maintenance of ecological diversity. We ... -
Fire and herbivory drive fungal and bacterial communities through distinct above- and belowground mechanisms
(Peer reviewed; Journal article, 2021)Fire and herbivory are important natural disturbances in grassy biomes. Both drivers are likely to influence be- lowground microbial communities but no studies have unravelled the long-term impact of both fire and herbiv- ... -
Fire and herbivory shape soil arthropod communities through habitat heterogeneity and nutrient cycling in savannas
(Peer reviewed; Journal article, 2021)Soil arthropods are important components of savannas, contributing to nutrient cycling and thus primary productivity. To investigate how fire and mammalian herbivores influ- ence arthropod food webs, we used two long term ... -
The firebug Pyrrhocoris apterus (Linnaeus, 1758) (Hemiptera, Heteroptera) new to the Norwegian fauna – with an explosive expansion in Northern Europe
(Journal article, 2020)The Firebug Pyrrhocoris apterus (Linnaeus, 1758) (Hemiptera, Heteroptera) is presented new to the Norwegian fauna. Several hundred individuals were observed in a residential area in southeast Norway, centred around two ... -
First case of chronic wasting disease in Europe in a Norwegian free‑ranging reindeer
(Journal article; Peer reviewed, 2016)Chronic wasting disease (CWD) is a fatal contagious prion disease in cervids that is enzootic in some areas in North America. The disease has been found in deer, elk and moose in the USA and Canada, and in South Korea ... -

First circumpolar assessment of Arctic freshwater phytoplankton and zooplankton diversity: Spatial patterns and environmental factors
(Peer reviewed; Journal article, 2021)1. Arctic freshwaters are facing multiple environmental pressures, including rapid climate change and increasing land-use activities. Freshwater plankton assemblages are expected to reflect the effects of these stressors ... -
First detection of highly pathogenic avian influenza virus in Norway
(Peer reviewed; Journal article, 2021)Background: Several outbreaks of highly pathogenic avian influenza (HPAI) caused by influenza A virus of subtype H5N8 have been reported in wild birds and poultry in Europe during autumn 2020. Norway is one of the few ... -
First observation of fouling of externally attached radio transmitters in an African river
(Others, 2020)Fouling of externally attached tags is an important consideration in long-term tagging studies as it may affect fish behaviour and well-being. Two externally attached radio transmitters on African tigerfish Hydrocynus ... -
First pre-modern record of the gyrfalcon (Falco rusticolus) in north-east Greenland
(Journal article; Peer reviewed, 2019)Gyrfalcon (Falco rusticolus) is the largest falcon in the world. It inhabits a wide range of climate zones in the Northern Hemisphere, from boreal forests in the south of its range to the arid polar deserts of the High ... -
