(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 ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)The new species Lecidella varangricaHaugan & Tønsberg is described from the northern shores of the Varanger Peninsula, Finnmark, Norway. It probably belongs to the saxicolous L. asemagroup by having ...

Linking geology and microbiology: Inactive pockmarks affect sediment microbial community structure (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Pockmarks are geological features that are found on the bottom of lakes and oceans all over the globe. Some are active, seeping oil or methane, while others are inactive. Active pockmarks are well studied since they harbor ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Long-distance dispersal (LDD) processes influence the founder effect on islands.We use genetic data for 25 Atlantic species and similarities among regional floras to analyse colonization, and test whether the genetic founder ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Long-term data from marked animals provide a wealth of opportunities for studies with high relevance to both basic ecological understanding and successful management in a changing world. The key strength of such data is ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Sperm swimming performance affects male fertilization success, particularly in species with high sperm competition.
