Benthic invertebrates in Svalbard fjords—when metabarcoding does not outperform traditional biodiversity assessment
(Journal article; Peer reviewed, 2022)To protect and restore ecosystems and biodiversity is one of the 10 challenges identified by the United Nations’s Decade of the Ocean Science. In this study we used eDNA from sediments collected in two fjords of the Svalbard ... -
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 ... -
Disaggregation bands as an indicator for slow creep activity on blind faults
(Journal article; Peer reviewed, 2022)Hidden, blind faults have a strong seismic hazard potential. Consequently, there is a great demand for a robust geological indicator of neotectonic activity on such faults. Here, we conduct field measurements of disaggregation ... -
TitaniQ temperatures and textural analysis as a record of the deformation history in a major continental shear zone system, Borborema Province, Brazil
(Journal article; Peer reviewed, 2022)We combine quartz textural analysis with Titanium-in-quartz (TitaniQ) geothermometry to investigate the late stages of deformation in mylonitic rocks from the Sucuru dike swarm in the Borborema Province. The wide range in ... -
Linked seasonality between a phoretic mite and its moth fly host (Parasitiformes: Mesostigmata and Diptera: Psychodidae)
(Journal article; Peer reviewed, 2022)Phoresy is a widespread phenomenon in mites. It allows mesostigmatid mites that are associated with ephemeral habitats such as mammal dung to travel fast on larger animals that can detect a proper habitat from a greater ... -
Sexual dimorphism and phylogenetic position of Chilodendron (Coleoptera: Curculionidae: Scolytinae) – a long isolated lineage endemic to Madagascar
(Journal article; Peer reviewed, 2022)Chilodendron Schedl, 1953 is resurrected as a valid genus based on Chilodendron planicolle Schedl, 1953. This is the only representative of the tribe Hylesinini Erichson, 1836 found on Madagascar and a molecular phylogenetic ... -
Placoid scales in bioluminescent sharks: Scaling their evolution using morphology and elemental composition
(Journal article; Peer reviewed, 2022)Elasmobranchs are characterised by the presence of placoid scales on their skin. These scales, structurally homologous to gnathostome teeth, are thought to have various ecological functions related to drag reduction, ... -
Mites (Oribatida and Mesostigmata) and vegetation as complementary bioindicators in peatlands
(Journal article; Peer reviewed, 2022)Vegetation is widely used in the assessment of the quality of peatlands, while the invertebrate fauna of peatlands is relatively poorly studied. We compared the bioindicator values of vegetation with two arthropod groups ... -
A review of the scientific knowledge of the seascape off Dronning Maud Land, Antarctica
(Journal article; Peer reviewed, 2022)Despite the exclusion of the Southern Ocean from assessments of progress towards achieving the Convention on Biological Diversity (CBD) Strategic Plan, the Commission for the Conservation of Antarctic Marine Living Resources ... -
Molecular identification and first demographic insights of sharks based on artisanal fisheries bycatch in the Pacific Coast of Colombia: implications for conservation
(Journal article; Peer reviewed, 2022)The Pacific coast of Colombia is characterized by mangrove ecosystems which play a crucial role as possible nurseries for juvenile sharks. However, trophic food webs from coastal ecosystems are heavily disturbed by increased ... -
Taxonomic Identification of Two Poorly Known Lantern Shark Species Based on Mitochondrial DNA From Wet-Collection Paratypes
(Journal article; Peer reviewed, 2022)Etmopteridae (lantern sharks) is the most species-rich family of sharks, comprising more than 50 species. Many species are described from few individuals, and re-collection of specimens is often hindered by the remoteness ... -
Trophic position of Otodus megalodon and great white sharks through time revealed by zinc isotopes
(Journal article; Peer reviewed, 2022)Diet is a crucial trait of an animal’s lifestyle and ecology. The trophic level of an organism indicates its functional position within an ecosystem and holds significance for its ecology and evolution. Here, we demonstrate ... -
Simultaneous barcode sequencing of diverse museum collection specimens using a mixed RNA bait set
(Journal article; Peer reviewed, 2022)A growing number of publications presenting results from sequencing natural history collection specimens reflect the importance of DNA sequence information from such samples. Ancient DNA extraction and library preparation ... -
The enigmatic tropical alpine flora on the African sky islands is young, disturbed, and unsaturated
(Journal article; Peer reviewed, 2022)Tropical alpine floras are renowned for high endemism, spectacular giant rosette plants testifying to convergent adaptation to harsh climates with nightly frosts, and recruitment dominated by long-distance dispersal from ... -
Setting the baseline for the dynamics of siphonophores and hydromedusae in Oslofjorden
(Journal article; Peer reviewed, 2022)Knowledge of the spatio-temporal dynamics of hydromedusae and siphonophores is scarce despite their key role as predators. In the temperate inlet of Oslofjorden, studies dealing with these organisms are limited to a few ... -
A new species of Sagiolechia (Sagiolechiaceae) from Norway, with lirelliform ascomata and 1-septate ascospores
(Journal article; Peer reviewed, 2021)The new species Sagiolechia monoseptata is described from the northern boreal zone of Norway where it was found on a shaded siliceous rock under a boulder in a north-facing, small, steep scree. It is characterized by the ... -
Marchantiana asserigena, a genus and species new to Norway
(Journal article; Peer reviewed, 2021)Marchantiana asserigena is reported new to Norway from the south-west (counties Rogaland, Hordaland, Sogn og Fjordane, and Møre og Romsdal) at altitudes from near sea level to 393 m. It occurs on branches of trees and ... -
Lepraria lobificans (syn. L. santosii) and L. sylvicola new to northern Europe from Norway
(Journal article; Peer reviewed, 2021)The two lichen species Lepraria lobificans (syn. L. santosii) and L. sylvicola are reported new to northern Europa, based on collections from Western Norway and Northern Norway, respectively. The specimens were identified ... -
