(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract The macroscopic single-celled green alga Acetabularia acetabulum has been a model system in cell biology for more than a century. However, no genomic information is available from this species. Since the alga has ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Little is known about when and how planktonic species arise and persist in the open ocean without apparent dispersal barriers. Pteropods are planktonic snails with thin shells susceptible to dissolution that are ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Extant Canis lupus genetic diversity can be grouped into three phylogenetically distinct clades: Eurasian and American wolves and domestic dogs.1 Genetic studies have suggested these groups trace their origins to a wolf ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Many species, including humans, have emerged via complex reticulate processes involving hybridisation. Under certain circumstances, hybridisation can cause distinct lineages to collapse into a single lineage with an admixed ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 1999)The genus Nothochrysa is reported for the first time from Norway. The two species N. flaviceps (Stephens, 1836) and N. capitata (Fabricius, 1793) were captured in light-traps in Kristiansand (VAY) in 1999. The biology and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Most pegmatites of southern Norway seem to be derived from anatectic melting of metamorphic rocks during the Sveconorwegian orogeny rather than to be highly evolved residual melts derived from granites. We test this ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Long-term observations of ice phenology in lakes are ideal for studying climatic variation in time and space. We used a large set of observations from 1890 to 2020 of the timing of freeze-up and break-up, and the length ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Aim Biodiversity hotspots are widely used as conservation priorities to preserve the tree of life. However, many conservation practices identify biodiversity hotspots without considering phylogenetic diversity (PD), ...
-
(Doctoral thesis / Doktoravhandling, 2009)As a starting point GIS (geographical information systems) seem intuitively to be a practical tool for biologists performing ecological research. GIS conveniently stores, explores, analyses and visualizes biological/ecol ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Glaciers cover ∼10% of the Earth’s land surface, but they are shrinking rapidly across most parts of the world, leading to cascading impacts on downstream systems. Glaciers impart unique footprints on river flow at times ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The European Space Agency’s Sentinel satellites have laid the foundation for global land use land cover (LULC) mapping with unprecedented detail at 10 m resolution. We present a cross-comparison and accuracy assessment of ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Animals can be important in modulating ecosystem-level nutrient cycling, although their importance varies greatly among species and ecosystems. Nutrient cycling rates of individual animals represent valuable data for testing ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation ...
-
Global patterns of Rhododendron diversity: The role of evolutionary time and diversification rates (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Aim: Understanding the evolution of the latitudinal diversity gradient (i.e. increase in species diversity towards the tropics) is a prominent issue in ecology and biogeography. Disentangling the relative contributions of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)The main aim of this paper is to address consequences of climate warming on loss of habitat and genetic diversity in the enigmatic tropical alpine giant rosette plants using the Ethiopian endemic Lobelia rhynchopetalum as ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract A multitude of landscape characterisation and mapping methods exist, but few methods take into account that landscapes properties vary in a gradual, continuous manner along multiple directions of variation. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract The GREENPEG project, which is funded by the European Commission Horizon 2020 ‘Climate action, environment, resource efficiency and raw materials’ programme, aims to develop multimethod exploration toolsets for ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Changes in growth forms frequently accompany plant adaptive radiations, including páramo–a high‐elevation treeless habitat type of the northern Andes. We tested whether diverse group of Senecio inhabiting montane forests ...
-
(Doctoral thesis / Doktoravhandling, 2014)The present PhD thesis, entitled “Gyrodactylids on European salmonids hosts: genomics, phylogeography and speciation”, presents a number of significant contributions to the field of evolutionary biology. It offers novel ...
