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. ... -
Fading opportunities for mitigating agriculture-environment trade-offs in a south American deforestation hotspot
(Peer reviewed; Journal article, 2021)Strong trade-offs between agriculture and the environment occur in deforestation frontiers, particularly in the world's rapidly disappearing tropical and subtropical dry forests. Pathways to mitigate these trade-offs are ... -
Failure to coordinate management in transboundary populations hinders the achievement of national management goals: The case of wolverines in Scandinavia
(Peer reviewed, 2019-03-09)Large carnivores are expanding in Europe, and their return is associated with con- flicts that often result in policies to regulate their population size through culling. Being wide-ranging species, their populations are ... -
Faunistic data and biology on the subfamily Cerocephalinae (Hymenoptera, Pteromalidae) including the first record of Theocolax formiciformis Westwood, 1832 from Norway
(Journal article; Peer reviewed, 2018)A single specimen of Theocolax formiciformis Westwood, 1832 is reported together with new data on Cerocephala cornigera Westwood, 1832 and Cerocephala rufa (Walker, 1833) in Norway. Notes on the mating behaviour of C. ... -
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, 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 ... -
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 ... -

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- ... -

(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 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 ... -
First record of Spalangiopelta Masi, 1922 (Hymenoptera, Pteromalidae, Ceinae) in Norway
