Morphological evidence supports splitting of species in the North Atlantic Sebastes spp. complex
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-02-06)The redfishes (genus Sebastes) are long-lived, commercial species in the North Atlantic. Excessive harvest through decades has led to a decline in the mature population of golden redfish (Sebastes norvegicus) in Norwegian waters, which is currently considered severely depleted. Accumulating genetic evidence suggests a more complex structure within this genus in the North Atlantic, which has ... -
Trail cameras can greatly inflate nestpredation rates
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-27)Photographic monitoring currently provides the most accurate means for identifying nest predators and eventually their role in bird population declines worldwide. However, previous studies have found that commercially available trail cameras represent an artificial structure that tend to negatively bias predation rates, likely through predator neophobia. Based on an experiment in Arctic tundra, ... -

Five millennia of mitonuclear discordance in Atlantic bluefin tuna identified using ancient DNA
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-02-07)Mitonuclear discordance between species is readily documented in marine fishes. Such discordance may either be the result of past natural phenomena or the result of recent introgression from previously seperated species after shifts in their spatial distributions. Using ancient DNA spanning five millennia, we here investigate the long-term presence of Pacific bluefin tuna (Thunnus orientalis) and ... -
Accuracy of serological tests for bovine brucellosis: A systematic review and meta-analysis

Tilrettelegging for friluftsliv
(Chapter; Bokkapittel, 2025-01-02)Den rette linja mellom to punkter i landskapet er ikke alltid den raskeste. Det lønner seg ofte å gå i buer, for å unngå bratte skrenter, komme rundt et stup, eller bare en oppgått sti. Stier slynger seg mellom fjell og gjennom søkk og daler der det er lettest å ta seg frem. Enkelte steder er stiene bearbeidet, eller tilrettelagt som man gjerne kaller det; klopper over myrer, bruer over elver, trapper ... -
