Inclusion of juvenile stages improves diversity assessment and adds to our understanding of mite ecology – A case study from mires in Norway
(Journal article; Peer reviewed, 2022)Arachnid orders, Mesostigmata, Trombidiformes, and Sarcoptiformes, commonly known as ‘mites’, are abundant in mires, both as adults and as juveniles. However, due to the challenges of identification, the juvenile forms are ... -
Incubation behaviour of the Common Ringed Plover Charadrius hiaticula at different latitudes
(Journal article; Peer reviewed, 2023)In biparental Charadriinae plovers, male and female incubation duties often resemble daily routines, with males typically incubating at night and females incubating during the day. By analysing incubation behaviour in three ... -
Infaunal and epifaunal secondary production in the Barents Sea, with focus on snow crab (Chionoecetes opilio) prey resources and consumption
(Journal article; Peer reviewed, 2022)Since the first observation of snow crab (Chionoecetes opilio) in the Barents Sea in 1996, the population has increased significantly, supporting a commercial fishery on the Norwegian shelf since 2012. To investigate whether ... -
Integrated Taxonomic Revision of Afrotropical Xyleborinus (Curculionidae: Scolytinae) Reveals High Diversity After Recent Colonization of Madagascar
(Journal article; Peer reviewed, 2021)The ambrosia beetle genus Xyleborinus Reitter, 1913 is particularly species rich in Madagascar where the genus exhibits extraordinary morphological variation not seen elsewhere. This study provides the first detailed ... -
An integrative geochronological framework for the Pleistocene So'a basin (Flores, Indonesia), and its implications for faunal turnover and hominin arrival
(Journal article; Peer reviewed, 2022)Flores represents a unique insular environment with an extensive record of Pleistocene fossil remains and stone artefacts. In the So'a Basin of central Flores these include endemic Stegodon, Komodo dragons, giant tortoises, ... -
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 Jurassic to Late Cretaceous canyons on the Måløy Slope: Source to sink fingerprints on the northernmost North Sea rift margin, Norway
(Journal article; Peer reviewed, 2021)The Måløy Slope is a key area for studying the connection between onshore and offshore geology of South Norway. It has functioned as an area of bypass, erosion and deposition between the Norwegian mainland source area and ... -
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 ... -
