(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The helminth fauna of brown trout (Salmo trutta) in the Norwegian subalpine lake, Øvre Heimdalsvatn was studied by examination of gills, eyes, body cavity, kidney, stomach, pyloric region and intestine in a total of 112 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)With the advent of high-throughput genome sequencing, bioinformatics training has become essential for research in evolutionary biology and related fields. However, individual research groups are often not in the position ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The palaeontology of the Lower to Middle Triassic succession in Spitsbergen has been studied for more than a century and a half. Our ability to properly interpret the evolutionary and ecological implications of the faunas ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The Norwegian electrical energy supply system is based on hydropower. The now deregulated energy market has led to increased use of hydropeaking production, leading to greater fluctuations in discharge and water levels ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Background The rather species-poor oviparous gyrodactylids are restricted to South America. It was suggested that they have a basal position within the otherwise viviparous Gyrodactylidae. Accordingly, it ...

The mitochondrial genome of the red icefish (Channichthys rugosus) casts doubt on its species status (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Antarctic notothenioid fishes are recognised as one of the rare examples of adaptive radiation in the marine system. Withstanding the freezing temperatures of Antarctic waters, these fishes have diversified into ...
