(Doctoral thesis / Doktoravhandling, 2020)This thesis focuses on the fungus gnat genus Allodia in the dipteran family Mycetophilidae. Allodia has historically gone through several systematic changes, with additions and exclusions of taxa, and the diversity and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Our knowledge of the diversity and distribution of many groups of lichens remains poor due to unclear species boundaries and challenging species identification. We have studied the medium sized to large foliose lichen ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)During efforts to generate DNA barcodes for all European Lepidoptera, Batrachedra pinicolella (Zeller, 1839) was found to comprise two genetically distinct clusters. Morphological investigation and results from two nuclear ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The evolutionary history of the wolf-like canids of the genus Canis has been heavily debated, especially regarding the number of distinct species and their relationships at the population and species level [1, 2, 3, 4, 5, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract To understand how species evolve and adapt to changing environments, it is important to study gene flow and introgression due to their influence on speciation and radiation events. Here, we apply a novel ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Species invasions are a global problem of increasing concern, especially in highly connected aquatic environments. Despite this, salinity conditions can pose physiological barriers to their spread, and understanding them ...

The invertebrate fauna of anthropogenic soils in the High-Arctic settlement of Barentsburg, Svalbard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)The terrestrial environment of the High Arctic consists of a mosaic of habitat types. In addition to the natural habitat diversity, various human-influenced types may occur. For the resident invertebrate fauna, these ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Telomere length is related to aging in many eukaryotes and the rate of telomere attrition has been suggested to reflect individual genetic quality. Telomere length could thus have implications for mate choice. We investigated ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract The hyoid apparatus is essential for underwater feeding in marine tetrapods, but it is unclear whether this complex has evolved as convergently as other traits, such as dentition or locomotion. Here we compare the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)Background During the last 15 years the internal transcribed spacer (ITS) of nuclear DNA has been used as a target for analyzing fungal diversity in environmental samples, and has recently been selected as ...
-
(Research report / Forskningsrapport, 2020)Denne rapporten beskriver kortfattet hvordan to naturtypekart ved Finse ble lagd. Resultatene er lagt fram i form av kart og tabeller, samt tekst som beskriver naturtypenes økologi. Arealdekkende naturtypekart etter NiN ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Recent technological developments have made genome sequencing and assembly highly accessible and widely used. However, the presence in sequenced organisms of certain genomic features such as high heterozygosity, polyploidy, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The alpine treeline ecotone is expected to move upwards in elevation with global warming. Thus, mapping treeline ecotones is crucial in monitoring potential changes. Previous remote sensing studies have focused on the usage ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Fluorite is one of the most common minerals in the crust and is of widespread economic importance. It shows strong UV-excited luminescence, variously attributed to defects within the fluorite structure and lanthanide ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Balancing selection, an evolutionary force that retains genetic diversity, has been detected in multiple genes and organisms, such as the sexual mating loci in fungi. However, to quantify the strength of balancing selection ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Humeri of Pessopteryx nisseri and vertebrae referred to Cymbospondylus sp. are described from the Lower Saurian niveau at Marmierfjellet, Spitsbergen. This is the most well-preserved Cymbospondylus material described from ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Among life history traits, offspring size has one of the most direct impacts on fitness, influencing growth, recruitment and survival of the individual, therefore affecting population, and ultimately macroevolutionary ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)1. Distinguishing correlative and causal connections among time series is an important challenge in evolutionary biology, ecology, macroevolution and palaeobiology. 2. Here, we present layeranalyzer, an r package that ...
-
(Doctoral thesis / Doktoravhandling, 2022)To bolster restoration efforts necessary to mitigate environmental degradation, relevant indicators, measurable targets, and assessments of ecosystems’ progress towards recovery are essential. These are particularly important ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)A molecular phylogenetic analysis based on the DNA barcode marker (nrITS) of 12 specimens of Lecidea leucothallina revealed three monophyletic clades, two apotheciate and one sorediate. The sorediate clade is described as ...
