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 ... -
The era of reference genomes in conservation genomics
(Journal article; Peer reviewed, 2022)Progress in genome sequencing now enables the large-scale generation of reference genomes. Various international initiatives aim to generate reference genomes representing global biodiversity. These genomes provide unique ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Diet of three sympatric species of granivorous songbirds in a Norwegian high mountain area during the early breeding season
(Journal article; Peer reviewed, 2022)Stomach samples of Lapland Longspur Calcarius lapponicus, Snow Bunting Plectrophenax nivalis, and Horned Lark Eremophila alpestris were collected at Hardangervidda in an early phase of the breeding season (during egg-laying ... -
The distribution of lichens and mosses at Edward VII Peninsula, Marie Byrd Land, Antarctica
(Journal article; Peer reviewed, 2022)This is the first detailed study of the distribution of mosses and lichens at Alexandra Mountains and Rockefeller Mountains, Edward VII Peninsula, Antarctica. A total of 418 samples was collected on 21 nunataks in 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 ... -
Global patterns of species richness of the holarctic alpine herb Saxifraga: The role of temperature and habitat heterogeneity
(Journal article; Peer reviewed, 2022)The effects of contemporary climate, habitat heterogeneity and long-term climate change on species richness are well studied for woody plants in forest ecosystems, but poorly understood for herbaceous plants, especially ... -
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, ... -
Walruses on the Dnieper: new evidence for the intercontinental trade of Greenlandic ivory in the Middle Ages
(Journal article; Peer reviewed, 2022)Mediaeval walrus hunting in Iceland and Greenland—driven by Western European demand for ivory and walrus hide ropes—has been identified as an important pre-modern example of ecological globalization. By contrast, the main ... -
