Ocean current connectivity propelling the secondary spread of a marine invasive comb jelly across western Eurasia
(Peer reviewed; Journal article, 2018-07-24)Aim: Invasive species are of increasing global concern. Nevertheless, the mechanisms driving further distribution after the initial establishment of non‐native species remain largely unresolved, especially in marine systems. ... -
Odd family reunion: DNA barcoding reveals unexpected relationship between three hydrozoan species
(Journal article; Peer reviewed, 2023-04-10)Knowledge of life histories is crucial for understanding ecological and evolutionary processes, but for many hydrozoan species only incomplete life cycles have been described due to challenges in linking hydromedusae with ... -
On a new species of Amphilochus from deep and cold Atlanic waters, with a note on the genus Amphilochopsis (Amphipoda, Gammaridea, Amphilochidae)
(Peer reviewed; Journal article, 2018)Amphilochus manudens and Amphilochopsis hamatus are redescribed based on specimens from the BioIce, Mareano, and IceAGE programmes. The new species Amphilochus anoculus sp. n. is described based on material from the IceAGE ... -
On the typification of the lichen genus Lepra Scop.
(Peer reviewed; Journal article, 2019)The first typification of Lepra Scop. by Pertusaria discoidea (Pers.) Malme (= Lepra albescens (Hudson) Hafellner), made in the Paris Code (1956), is shown to be correct after studies of the original material in the Micheli ... -
Onisimus turgidus (Sars, 1879) (Amphipoda, Uristidae), an overlooked amphipod from sea anemones in Northern Norway
(Journal article; Peer reviewed, 2020)Two Norwegian uristid amphipods, obligate associates of sea anemones, have for a long time been confused sub nomine Onisimus normani Sars, 1890. In reality this species only occurs in south Norway, while the north-Norwegian ... -
Origin and evolution of fungus farming in wood-boring Coleoptera – a palaeontological perspective
(Journal article; Peer reviewed, 2021)Insect–fungus mutualism is one of the better-studied symbiotic interactions in nature. Ambrosia fungi are an ecological assemblage of unrelated fungi that are cultivated by ambrosia beetles in their galleries as obligate ... -
Original specimens and type localities of early described polychaete species (Annelida) from Norway, with particular attention to species described by O.F. Müller and M. Sars
(Peer reviewed; Journal article, 2014)Early descriptions of species from Norwegian waters are reviewed, with a focus on the basic requirements for reassessing their characteristics, in particular, by clarifying the status of the original material and locating ... -
Palaeoproteomics of fossil bird bones for taxonomic classification
(Peer reviewed; Journal article, 2019)We used proteomic profiling to taxonomically classify extinct, alongside extant bird species using mass spectrometry on ancient bone-derived collagen chains COL1A1 and COL1A2. Proteins of Holocene and Late Pleistocene-aged ... -
Paleomagnetic correlations between scandinavian ice-sheet fluctuations and greenland dansgaard–oeschger events, 45,000–25,000 yr B.P.
(Peer reviewed; Journal article, 2003)Two paleomagnetic excursions, the Skjong correlated with the Laschamp (about 41,000 GISP2 yr B.P.) and the Valderhaug correlated with the Mono Lake (about 34,000 GISP2 yr B.P.), have been identified in stratigraphic ... -
Parthenogenetic vs. sexual reproduction in oribatid mite communities
(Peer reviewed; Journal article, 2019)The dominance of sex in Metazoa is enigmatic. Sexual species allocate resources to the production of males, while potentially facing negative effects such as the loss of well‐adapted genotypes due to recombination, and ... -
Patterns of coevolution of ambrosia beetle mycangia and the Ceratocystidaceae, with five new fungal genera and seven new species
(Peer reviewed; Journal article, 2020)Ambrosia beetles farm specialised fungi in sapwood tunnels and use pocket-like organs called mycangia to carry propagules of the fungal cultivars. Ambrosia fungi selectively grow in mycangia, which is central to the ... -
Patterns of diversification amongst tropical regions compared: a case study in Sapotaceae
(Peer reviewed; Journal article, 2014-12-03)Species diversity is unequally distributed across the globe, with the greatest concentration occurring in the tropics. Even within the tropics, there are significant differences in the numbers of taxa found in each continental ... -
Pelagic deep‑sea fauna observed on video transects in the southern Norwegian Sea
(Journal article; Peer reviewed, 2021)Observations of the diversity, distribution and abundance of pelagic fauna are absent for many ocean regions in the Atlantic, but baseline data are required to detect changes in communities as a result of climate change. ... -

A phylogenetic and taxonomic assessment of Afrotropical Micracidini (Coleoptera, Scolytinae) reveals a strong diversifying role for Madagascar
(Journal article; Peer reviewed, 2021)Afrotropical bark beetle genera in the tribe Micracidini are revised and an identification key provided. The new classification is based on phylogenetic analyses of five molecular markers (COI, EF-1α, 28S, PABP1, CAD) in ... -
Phylogenetic conservatism and biogeographic affinity influence woody plant species richness–climate relationships in eastern Eurasia
(Journal article; Peer reviewed, 2020)Mechanisms underlying species richness patterns remain a central yet controversial issue in biology. Climate has been regarded as a major determinant of species richness. However, the relative influences of different ... -
The phylogenetic systematics of Spilomelinae and Pyraustinae (Lepidoptera: Pyraloidea: Crambidae) inferred from DNA and morphology
(Peer reviewed; Journal article, 2019)Spilomelinae and Pyraustinae form a species-rich monophylum of Crambidae (snout moths). Morphological distinction of the two groups has been difficult in the past, and the morphologically heterogenous Spilomelinae has not ... -
Phylogenomics of Aplacophora (Mollusca, Aculifera) and a solenogaster without a foot
(Peer reviewed; Journal article, 2019)Recent molecular phylogenetic investigations strongly supported the placement of the shell-less, worm-shaped aplacophoran molluscs (Solenogastres and Caudofoveata) and chitons (Polyplacophora) in a clade called Aculifera, ...
