The enigmatic tropical alpine flora on the African sky islands is young, disturbed, and unsaturated (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Significance Resilience is required to withstand or mitigate the effect of human-induced climate change. Today whole ecosystems are affected by climate change, but our understanding of their evolution and natural ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Progress in genome sequencing now enables the large-scale generation of reference genomes. Various international initiatives aim to generate reference genomes representing global biodiversity. These genomes provide unique ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The oral microbiome plays key roles in human biology, health, and disease, but little is known about the global diversity, variation, or evolution of this microbial community. To better understand the evolution and changing ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The early Palaeozoic Era records the initial biodiversification of the Phanerozoic. The increase in biodiversity involved drastic changes in taxon longevity, and in rates of origination and extinction. Here, we calculate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We provide a biochronology of Jurassic planktonic foramininfera, using first order linkage to ammonite and nannofossil stratigraphy and geochronology. This enigmatic and understudied group of microfossils occurred from ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)A male specimen of Phyllonorycter schreberella (Fabricius, 1781) (Lepidoptera: Gracillariidae) was found in western Norway in Vestland at Lærdal: Husum in June 2021. The circumstances of the record, the species' biology, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We report the presence of the North American Crangonyx floridanus co-occurring with C. pseudogracilis in two Irish rivers, following surveys in three rivers, eleven lake sites and an ornamental pond in 2020. This is the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Over the last two decades, the use of DNA barcodes has transformed our ability to identify and assess life on our planet. Both strengths and weaknesses of the method have been exemplified through thousands of peer-reviewed ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract The great gerbil (Rhombomys opimus) is a social rodent living in permanent, complex burrow systems distributed throughout Central Asia, where it serves as the main host of several important vector-borne ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract The repeated, rapid and often pronounced patterns of evolutionary divergence observed in insular plants, or the ‘plant island syndrome’, include changes in leaf phenotypes, growth, as well as the acquisition of a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The genus Cosmosphorus Ratzeburg, 1848 (Hymenoptera, Euphorinae) is revised for Norway. The three species Cosmophorus klugi Ratzeburg, 1848, C. regius Niezabitowski, 1910, and C. cembrae Ruschka, 1925 are recorded. A brief ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We distinguish five Xanthomendoza species in Norway, viz., X. borealis, X. fallax, X. fulva, X. oregana, and X. ulophyllodes, based on morphology and molecular evidence. This paper gives an updated taxonomy of the Norwegian ...

(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, 2018)The quartz-K-feldspar-cemented breccia of Berglia-Glassberget in the Lierne municipality in central Norway forms an ellipsoid structure 250 m × 500 m in size. The hydrothermal breccia is barren in terms of economic commodities ...
-
(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 ...
