Habitat Protection Approaches Facilitate Conservation of Overlooked Fungal Diversity–A Case Study From the Norwegian Coastal Heathland System
(Journal article; Peer reviewed, 2022)European coastal heathlands are distinct ecosystems shaped by land use tradition and they have experienced an 80% area reduction from their historical maximum. These mosaics of mires and wind exposed patches have ericaceous ... -
Head anatomy of a lantern shark wet-collection specimen (Chondrichthyes: Etmopteridae)
(Journal article; Peer reviewed, 2023)In this study, we apply a two-step (untreated and soft tissue stained) diffusible iodine-based contrast-enhanced micro-computed tomography array to a wet-collection Lantern Shark specimen of Etmopterus lucifer. The focus ... -
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 ... -
Heterogeneity on the abyssal plains: A case study in the Bering Sea
(Journal article; Peer reviewed, 2023)The abyssal plains are vast areas without large scale relief that occupy much of the ocean floor. Although long considered relatively featureless, they are now known to display substantial biological heterogeneity across ... -
Hiding in plain sight—Euplokamis dunlapae (Ctenophora) in Norwegian waters
(Journal article; Peer reviewed, 2021)Cydippid ctenophores of genus Euplokamis have been rarely reported from the north-east Atlantic in the scientific literature. The conspicuous lack of previous records is likely attributable to methodological constraints ... -
High Diversity of Mites (Acari: Oribatida, Mesostigmata) Supports the High Conservation Value of a Broadleaf Forest in Eastern Norway
(Journal article; Peer reviewed, 2021)Broadleaf forests are critical habitats for biodiversity and this biodiversity is in turn essential for their proper functioning. Mites (Acari) are a numerous and functionally essential component of these forests. We report ... -
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 ... -
Historical demographic processes dominate genetic variation in ancient Atlantic cod mitogenomes
(Journal article; Peer reviewed, 2021)Ancient DNA (aDNA) approaches have been successfully used to infer the long-term impacts of climate change, domestication, and human exploitation in a range of terrestrial species. Nonetheless, studies investigating such ... -
History and evolution of the afroalpine fora: in the footsteps of Olov Hedberg
(Journal article; Peer reviewed, 2021)The monumental work of Olov Hedberg provided deep insights into the spectacular and fragmented tropical alpine flora of the African sky islands. Here we review recent molecular and niche modelling studies and re-examine ... -
How complex is the Naineris setosa species complex? First integrative study of a presumed cosmopolitan and invasive annelid (Sedentaria: Orbiniidae)
(Journal article; Peer reviewed, 2023)We performed a comparative study of the specimens from the Naineris setosa complex from the Pacific and the Atlantic Oceans and re-described the syntype of N. setosa, including the selection of the lectotype. Molecular ... -
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, ... -
The identity of Psilochironomus Sublette, 1966 (Chironomidae, Chironominae, Pseudochironomini)
(Journal article; Peer reviewed, 2024)Chironomus fumeus Walley in Curran, 1934 was described based on a single male from British Guyana. When reviewing the type specimens of Chironomidae (Diptera) in the American Museum of Natural History, Sublette erected the ... -
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 ... -
