(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Aim Many thematic land cover maps, such as maps of vegetation types, are based on field inventories. Studies show inconsistencies among field workers in such maps, explained by inter-observer variation in classification ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Legally protected plants are illegally traded through online sales platforms and orchids are a significant component of this wildlife trade. This study focused on salep, a compound product made from wild collected orchid ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Quartz from 254 pegmatites representing eight pegmatite fields and provinces worldwide was investigated by laser-ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) to determine concentrations of trace elements ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Populations of large mammals have declined at alarming rates, especially in areas with intensified land use where species can only persist in small habitat fragments. To support conservation planning, we developed habitat ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)To determine the present-day community composition of siliceous Rhizaria (Radiolaria and Phaeodaria) in Norwegian fjords, plankton tows were conducted in south-western and northern Norwegian fjords in September 2016. The ...

Range contraction and increasing isolation of a polar bear subpopulation in an era of sea ice loss (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Climate change is expected to result in range shifts and habitat fragmentation for many species. In the Arctic, loss of sea ice will reduce barriers to dispersal or eliminate movement corridors, resulting in increased ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Gene expression changes potentially play an important role in adaptive evolution under human‐induced selection pressures, but this has been challenging to demonstrate in natural populations. Fishing exhibits strong selection ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Investigation of bryozoan faunas collected in two submarine caves in Lesvos Island, Aegean Sea revealed a great number of colonies of three species currently assigned to the cheilostome family Onychocellidae: Onychocella ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)Background The temporal origin and diversification of orchids (family Orchidaceae) has been subject to intense debate in the last decade. The description of the first reliable fossil in 2007 enabled a direct ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Ethnopharmacological relevance What are the minimum methodological and conceptual requirements for an ethnopharmacological field study? How can the results of ethnopharmacological field studies be reported so that researchers ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Tropical ecosystems are undergoing unprecedented rates of degradation from deforestation, fire, and drought disturbances. The collective effects of these disturbances threaten to shift large portions of tropical ecosystems ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Much adaptive evolutionary change is underlain by mutational variation in regions of the genome that regulate gene expression rather than in the coding regions of the genes themselves. An understanding of the role of gene ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Both molecular and morphologic characters support the reinstatement of Leuctra biellensis Festa, 1942 as a valid species distinct from Leuctra nigra (Olivier, 1811). Genetic distances between L. biellensis and the different ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract The number of individuals of species varies, but estimating abundance, given incomplete and biased sampling in both contemporary and fossilized communities, is challenging. Here, we describe a new occupancy ...

Reliability in distribution modeling — A synthesis and step-by-step guidelines for improved practice (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Information about the distribution of a study object (e.g., species or habitat) is essential in face of increasing pressure from land or sea use, and climate change. Distribution models are instrumental for acquiring such ...
