Differential expression profiling of heat stressed tardigrades reveals major shift in the transcriptome
(Peer reviewed; Journal article, 2022)Tardigrades are renowned for their extreme stress tolerance, which includes the ability to endure complete desiccation, high levels of radiation and very low sub-zero temperatures. Nevertheless, tardigrades appear to be ... -
Differential patterns of floristic phylogenetic diversity across a post-glacial landscape
(Journal article; Peer reviewed, 2019)Aim: In this study, we explored spatial patterns of phylogenetic diversity (PD) and end-emism in the flora of Norway and tested hypothesized post-glacial environmental drivers of PD, including temperature, precipitation, ... -
Discovery of a silicate rock-boring organism and macrobioerosion in fresh water
(Journal article; Peer reviewed, 2018)Macrobioerosion is a common process in marine ecosystems. Many types of rock-boring organisms break down hard substrates, particularly carbonate rocks and calcareous structures such as dead corals and shells. In paleontology, ... -
Disentangling the identity of Lebertia porosa Thor, 1900 using integrative taxonomy (Acari: Hydrachnidia)
(Journal article; Peer reviewed, 2022)Initial analyses of DNA barcode data from Norwegian populations attributed to the water mite Lebertia porosa Thor, 1900 revealed large genetic divergence and potentially cryptic species level diversity. We used one ... -
Distribution, ecology and biomonitoring studies of epiphytic lichens on conifers
(Gunneria, 0332-8554; 68, Research report, 1994)This study presents the results of investigations of epiphytic lichens on conifers, mainly with a biomonitoring approach. The concentrations of nitrogen and sulphur measured in Hypogynmia physodes at 179 sites on a national ... -
Diverse Sphagnum mosses support rich moss mite communities (Acari, Oribatida) in mires of Western Norway
(Peer reviewed; Journal article, 2019)A study of oribatid mites was carried out in six mires located in western, oceanic parts of Norway. Twenty Sphagnum species of five subgenera were collected from microhabitats representing trophic state and wetness gradients. ... -
Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species
(Journal article; Peer reviewed, 2013)A total of 5 nudibranch species are reported from the Norwegian coast for the first time (Doridoxa ingolfiana, Goniodoris castanea, Onchidoris sparsa, Eubranchus rupium and Proctonotus mucroniferus). In addition 10 species ... -
Diversity, habitat endemicity and trophic ecology of the fauna of Loki’s Castle vent field on the Arctic Mid-Ocean Ridge
(Journal article; Peer reviewed, 2024)Loki’s Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field discovered on the Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of the LCVF has not ... -

DNA barcode data reveal biogeographic trends in Arctic non-biting midges
(Journal article; Peer reviewed, 2018)Chironomid flies (non-biting midges) are among the most abundant and diverse animals in Arctic regions, but detailed analyses of species distributions and biogeographical patterns are hampered by challenging taxonomy and ... -
DNA barcode reference libraries for the monitoring of aquatic biota in Europe: Gap-analysis and recommendations for future work
(Journal article; Peer reviewed, 2019)Effective identification of species using short DNA fragments (DNA barcoding and DNA metabarcoding) requires reliable sequence reference libraries of known taxa. Both taxonomically comprehensive coverage and content quality ... -
DNA barcodes and morphology reveal unrecognized species in Chironomidae (Diptera)
(Journal article; Peer reviewed, 2017)For over a decade, DNA barcoding has proven an effective modern tool in taxonomy, evolutionary biology and biodiversity research. Many new species have been discovered and described with DNA barcodes as part of their ... -
DNA barcodes provide insights into the diversity and biogeography of the non-biting midge Polypedilum (Diptera, Chironomidae) in South America
(Peer reviewed; Journal article, 2023)South America, particularly within its tropical belt, is renowned for its unparalleled high levels of species richness, surpassing other major biomes. Certain neotropical areas harbor fragmented knowledge of insect diversity ... -
DNA barcodes successfully delimit morphospecies in a superdiverse insect genus
(Journal article; Peer reviewed, 2018)Polypedilum Kieffer (Diptera: Chironomidae), with 520 currently known species worldwide, can be extremely difficult to identify species level based on the morphology. We used 3,670 cytochrome c oxidase subunit I (COI) ... -
DNA barcoding for species identification of insect skins: A test on Chironomidae (Diptera) pupal exuviae
(Journal article; Peer reviewed, 2017)Chironomidae (Diptera) pupal exuviae samples are commonly used for biological monitoring of aquatic habitats. DNA barcoding has proved useful for species identification of chironomid life stages containing cellular tissue, ... -
