Helmutneris vadum, a new species of Lumbrineridae (Annelida) from Lizard Island, Great Barrier Reef, Australia
(Journal article; Peer reviewed, 2020)A new species of Lumbrineridae, Helmutneris vadum n. sp., is described from shallow waters near Lizard Island, Great Barrier Reef, Queensland, Australia. The new species differs from two other known species of Helmutneris ... -
High genetic diversity of common toad (Bufo bufo) populations under strong natural fragmentation on a Northern archipelago
(Peer reviewed; Journal article, 2016-03)The last decades have shown a surge in studies focusing on the interplay between fragmented habitats, genetic variation, and conservation. In the present study, we consider the case of a temperate pond-breeding anuran (the ... -
Hybridization between the locally endangered Rosa spinosissima and Rosa mollis results in the pentaploid Rosa × sabinii in Western Norway
(Peer reviewed; Journal article, 2016-12)Rosa spinosissima is an endangered species in Norway, found only within a limited area on the southwestern coast. Presumed hybrid forms between R. spinosissima and rose species within R. sect. Caninae have been recorded ... -
Identification of the polyp stage of three leptomedusa species using DNA barcoding
(Peer reviewed; Journal article, 2017)DNA sequence data of hydromedusae and hydroids collected in the fjords near Bergen, Norway, permitted to connect three leptomedusae to three thecate hydroids with hitherto unknown life cycles. For all three species pairs, ... -
Integrative taxonomy reveals a cryptic species of the nudibranch genus Polycera (Polyceridae) in European waters
(Journal article; Peer reviewed, 2020)This work aimed to test whether the colour variability featured by the European nudibranch Polycera quadrilineata is consistent with the concept of a single polychromatic species or may hide multiple lineages. Samples from ... -
Integrative taxonomy reveals a new species, Nephroma orvoi, in the N. parile species complex (lichenized Ascomycota)
(Journal article; 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 ... -
Interrogating genomic-scale data to resolve recalcitrant nodes in the Spider Tree of Life
(Journal article; Peer reviewed, 2020)Genome-scale data sets are converging on robust, stable phylogenetic hypotheses for many lineages; however, some nodes have shown disagreement across classes of data. We use spiders (Araneae) as a system to identify the ... -
Intraspecific dental variations in the deep-sea shark Etmopterus spinax and their significance in the fossil record
(Journal article; Peer reviewed, 2020)An important character on several taxonomic levels for shark identification is the tooth morphology. Sharks show a variety of highly specialized dentitions reflecting adaptations to their feeding habits. Intraspecific ... -
Invasive ctenophore Mnemiopsis leidyi in Norway
(Peer reviewed; Journal article, 2015-03-18)We present data on the occurrence of the invasive ctenophore Mnemiopsis leidyi in Norway after the initial observations made in 2005. Our data comes from several net sampling investigations conducted along the Norwegian ... -
Is It Hop? Identifying Hop Fibres in a European Historical Context
(Peer reviewed; Journal article, 2019)Hop (Humulus lupulus L .) is an ancient perennial crop plant, native to the Northern Hemisphere. The archaeological evidence dates back to at least the sixth century ad in Europe. Hop has been used for beer brewing, in ... -
Jellyfish summer distribution, diversity and impact on fish farms in a Nordic fjord
(Peer reviewed; Journal article, 2017)Jellyfish can cause high mortality of farmed fish and hence significant economic losses for the aquaculture industry. Despite their socio-economic importance, distribution and diversity data on gelatinous plankton are ... -
Kin selection and polygyny: Can relatedness lower the polygyny threshold?
(Peer reviewed; Journal article, 2015)Resource polygyny incurs costs of having to share breeding resources for female breeders. When breeding with a relative, however, such costs may be lessened by indirect fitness benefits through kin selection, while benefits ... -
Late Pleistocene songbirds of Liang Bua (Flores, Indonesia); the first fossil passerine fauna described from Wallacea
(Peer reviewed; Journal article, 2017-08-17)Background: Passerines (Aves: Passeriformes) dominate modern terrestrial bird communities yet their fossil record is limited. Liang Bua is a large cave on the Indonesian island of Flores that preserves Late Pleistocene–Holocene ... -
Leaps and bounds: geographical and ecological distance constrained the colonisation of the Afrotemperate by Erica
(Peer reviewed; Journal article, 2019-12-05)Background The coincidence of long distance dispersal (LDD) and biome shift is assumed to be the result of a multifaceted interplay between geographical distance and ecological suitability of source and sink areas. Here, ... -
Lebetus scorpioides and Buenia jeffreysii (Teleostei: Gobiidae) found north of the Arctic Circle
(Peer reviewed; Journal article, 2016)Two gobiid species, Lebetus scorpioides and Buenia jeffreysii, were recorded in northern Norway, for the first time north of the Arctic Circle. While both species were found on the continental shelf west of the Lofoten ... -

(Peer reviewed; Journal article, 2018)The new species Lecidella varangrica Haugan & Tønsberg is described from the northern shores of the Varanger Peninsula, Finnmark, Norway. It probably belongs to the saxicolous L. asema group by having a pigmented hypothecium ... -
Lichens and associated fungi from Glacier Bay National Park, Alaska
(Journal article; Peer reviewed, 2020)Lichens are widely acknowledged to be a key component of high latitude ecosystems. However, the time investment needed for full inventories and the lack of taxonomic identification resources for crustose lichen and ... -
