First Molecular Phylogeny of Lumbrineridae (Annelida)
(Journal article; Peer reviewed, 2022-01-25)Lumbrineridae is a family of marine annelids with simple external morphology but complex and diverse jaw apparatuses consisting of paired maxillae and mandibles. Here we present the first phylogeny of lumbrinerids based ... -
Directed endozoochorous dispersal by scavengers facilitate sexual reproduction in otherwise clonal plants at cadaver sites
(Journal article; Peer reviewed, 2022)The regeneration niche of many plant species involves spatially and temporally unpredictable disturbances, called recruitment windows of opportunity. However, even species with clear dispersal adaptations such as fleshy ... -
Ancient DNA reveals a southern presence of the Northeast Arctic cod during the Holocene
(Journal article; Peer reviewed, 2022)Climate change has been implicated in an increased number of distributional shifts of marine species during the last century. Nonetheless, it is unclear whether earlier climatic fluctuations had similar impacts. We use ... -
Global raster dataset on historical coastline positions and shelf sea extents since the Last Glacial Maximum
(Journal article; Peer reviewed, 2022)Motivation: Historical changes in sea level caused shifting coastlines that affected the distribution and evolution of marine and terrestrial biota. At the onset of the Last Glacial Maximum (LGM) 26 ka, sea levels were ... -
New species of the genus Chimarra Stephens from Africa (Trichoptera, Philopotamidae) and characterization of the African groups and subgroups of the genus
(Journal article; Peer reviewed, 2022)This paper is primarily based on collections in Tanzania and Ghana in 1990–1991 and 1991–1994, respectively. In all, 46 species of Chimarra were collected, 31 of them new species. All these species are illustrated or ... -
Numbers of Horned Lark Eremophila alpestris are increasing at high alpine and arctic breeding sites in Norway
(Journal article; Peer reviewed, 2022)Strong declines in number of breeding Horned Larks Eremophila alpestris were reported from several Fennoscandian breeding grounds in the 1960s and 1970s. Counts from the species’ high alpine breeding grounds at Hardangervidda, ... -
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, ... -
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 ... -
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 ... -
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 ... -
