(Doctoral thesis / Doktoravhandling, 2016)The easier access to increasingly powerful computational approaches and tools in the field of distribution modelling, has contributed to a proliferation of data, applications, practitioners, guidelines, and novel theoretical ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Reconstructing past events of hybridization and population size changes are required to understand speciation mechanisms and current patterns of genetic diversity, and ultimately contribute to species' conservation. Sea ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract The fauna of streams in the High Arctic, dominated by chironomids, is shaped by extreme environmental conditions that represent the physiological limits for benthic invertebrates. Despite their ecological importance, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract The rapid diversification and high species richness of flowering plants is regarded as ‘Darwin’s second abominable mystery’. Today the global spatiotemporal pattern of plant diversification remains elusive. Using ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Norwegian landscapes are changing at an increasingly rapid rate and therefore systematically structured information about observable landscape variation is required for knowledge-based management of landscape diversity. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Phylogenetic analyses of 140 ITS sequences from Norwegian material of Peltigera sect. Peltigera obtained mainly by the Norwegian DNA barcode project OLICH indicate the presence of 26 putative species. Among those, we accept ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Ethnopharmalogical relevance In Africa, traditional medicine is important for local healthcare and plants used for these purposes are commonly traded. Identifying medicinal plants sold on markets is challenging, as leaves, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The Biatora vernalis- and meiocarpa-groups comprise species with pale beige to reddish brown apothecia and 0-, rarely also 1(–3)-septate ascospores. A DNA barcoding approach based on ITS sequences shows that these two ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Tubers of terrestrial orchids are harvested and traded from the eastern Mediterranean to the Caspian Sea for the traditional product Salep. Overexploitation of wild populations and increased middle-class prosperity have ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Background: The trade of plant roots as traditional medicine is an important source of income for many people around the world. Destructive harvesting practices threaten the existence of some plant species. Harvesters of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Herbs and spices are some of the most vulnerable products in terms of fraud and adulteration in the food sector. Although standard analytical methods are accurate for quality control of specific lead or marker compounds, ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)In eastern Mediterranean countries orchids continue to be collected from the wild for the production of salep, a beverage made of dried orchid tubers. In this study we used nrITS1 and nrITS2 DNA metabarcoding to identify ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Human population expansion and associated degradation of the habitat of many wildlife species cause loss of biodiversity and species extinctions. The small Simen Mountains National Park in Ethiopia is one of the last ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Airborne pollen monitoring is of global socio-economic importance as it provides information on presence and prevalence of allergenic pollen in ambient air. Traditionally, this task has been performed by microscopic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Biological specimens in natural history collections worldwide are increasingly being used in biogeographical, environmental, and taxonomic studies. For their meaningful use, correct species identification is crucial. For ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Genes of the major histocompatibility complex (MHC) are crucial for adaptive immunity in jawed vertebrates, and theory predicts that there should be mate choice for optimizing MHC constitution in the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Dental calculus and other preserved microbiome substrates are an attractive target for dietary reconstruction in past populations through a variety of physical, chemical, and molecular means. Recently, studies have attempted ...
-
(Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2023)The relevance of genetic constraints for evolutionary change beyond microevolutionary timescales is debated. The high evolvability of natural populations predicts rapid adaptation, but evolvability is often found to correlate ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Abstract We report on the occurrence of a new high-pressure Ca-Al-silicate in localized shock melt pockets found in the feldspatic lunar meteorite Oued Awlitis 001 and discuss the implications of our discovery. ...
-
(Research report / Forskningsrapport, 1955)Field note books Notebooks from a sampling project: collecting marine benthic invertebrates in the Oslofjord during the years 1951-1955. The project was organised from the Biological Station in Drøbak, University of ...
