(Doctoral thesis / Doktoravhandling, 2022)To bolster restoration efforts necessary to mitigate environmental degradation, relevant indicators, measurable targets, and assessments of ecosystems’ progress towards recovery are essential. These are particularly important ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)A molecular phylogenetic analysis based on the DNA barcode marker (nrITS) of 12 specimens of Lecidea leucothallina revealed three monophyletic clades, two apotheciate and one sorediate. The sorediate clade is described as ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)The new species Lecidella varangricaHaugan & Tønsberg is described from the northern shores of the Varanger Peninsula, Finnmark, Norway. It probably belongs to the saxicolous L. asemagroup by having ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 1998)The remarkable leafhopper Ledra aurita (Linnaeus, 1758) has been rediscovered in Norway. Three specimens were captured at light at Ø, Hvaler: Asmaløy (EIS 12) in July-Aug. 1995. An unpublished record from AK, Frogn: Drøbak ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; 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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The organic-rich shales of the Middle Triassic Botneheia Formation in Svalbard and its correlative units offshore are considered important source rock intervals for oil and gas generation in the Norwegian Barents Shelf ...

Linking geology and microbiology: Inactive pockmarks affect sediment microbial community structure (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Pockmarks are geological features that are found on the bottom of lakes and oceans all over the globe. Some are active, seeping oil or methane, while others are inactive. Active pockmarks are well studied since they harbor ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Long-distance dispersal (LDD) processes influence the founder effect on islands.We use genetic data for 25 Atlantic species and similarities among regional floras to analyse colonization, and test whether the genetic founder ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Long-term data from marked animals provide a wealth of opportunities for studies with high relevance to both basic ecological understanding and successful management in a changing world. The key strength of such data is ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Sperm swimming performance affects male fertilization success, particularly in species with high sperm competition. Understanding how sperm morphology impacts swimming performance is therefore important. Sperm swimming ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The long history of human land use have had a strong influence on ecosystems and landscapes in the boreal forest region of Northern Europe and created semi-natural habitats of high conservation value. In this study, we ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)The latitudinal biodiversity gradient, with tropical regions acting as ‘evolutionary cradles’, is a cornerstone of current biogeographical and ecological theory1. In the modern world floral biodiversity and biomass are ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Trace elements of quartz document the physical-chemical evolutions of quartz growth, which has been a great and most applied tool in the study of geological settings in quartz-forming environments. A classic method is using ...
-
(Doctoral thesis / Doktoravhandling, 2022)The Indo-Burma bioregion, as a global biodiversity hotspot, supports an exceptionally high biodiversity, but freshwater ecosystems are now increasingly impacted by human activities while biomonitoring approaches are lacking. ...
-
(Doctoral thesis / Doktoravhandling, 2020)All organisms need to fight pathogens to avoid infectious diseases. In vertebrates, two classes of polymorphic genes from the major histocompatibility complex (MHC) are crucial for triggering immune responses against ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)A range of published arguments against formalizing the Anthropocene as a geological time unit have variously suggested that it is a misleading term of non-stratigraphic origin and usage, is based on insignificant temporal ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)A new arrojadite-group mineral manganoarrojadite-(KNa), ideally KNa5MnFe13Al(PO4)11(PO3OH)(OH)2, was found in a phosphate-bearing granite pegmatite at the Palermo No. 1 mine, New Hampshire, USA. It forms anhedral grains ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Members of the class Mamiellophyceae comprise species that can dominate picophytoplankton diversity in polar waters. Yet, polar species are often morphologically indistinguishable from temperate species, although clearly ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The lesser Antilles archipelago in the Caribbean is known as a biodiversity hotspot, hosting many endemic species. However, recent introduction of a highly invasive species, the Australian redclaw crayfish (Cherax ...
