Spatio-temporal variation in large herbivore pressure in Norway during 1949-1999: has decreased grazing by livestock been countered by increased browsing by cervids?
(Journal article; Peer reviewed, 2011)During recent decades, rough livestock grazing has decreased markedly on unimproved land (i.e. natural and seminatural habitats) across most of Europe, whilst the number of wild cervids has increased. However, we still ... -
Spatiotemporal monitoring of the rare northern dragonhead (Dracocephalum ruyschiana, Lamiaceae) — SNP genotyping and environmental niche modeling herbarium specimens
(Journal article; Peer reviewed, 2022)The species we have studied the spatiotemporal genetic change in the northern dragonhead, a plant species that has experienced a drastic population decline and habitat loss in Europe. We have added a temporal perspective ... -
Spatiotemporal variation in climatic conditions across ecosystems
(Peer reviewed; Journal article, 2021)Environmental variation in time and space affects biological processes such as extinction risk and speed of adaptation to environmental change. The spatial structure of environmental variation may vary among ecosystems, ... -
Specialized sledge dogs accompanied Inuit dispersal across the North American Arctic
(Journal article; Peer reviewed, 2019)Domestic dogs have been central to life in the North American Arctic for millennia. The ancestors of the Inuit were the first to introduce the widespread usage of dog sledge transportation technology to the Americas, but ... -
Speciation in the genera Anthericum and Chlorophytum (Asparagaceae) in Ethiopia — a molecular phylogenetic approach
(Journal article; Peer reviewed, 2017)Sister group relations of Ethiopian species of Anthericum and Chlorophytum and variation patterns in the C. gallabatense and C. comosum complexes are studied using molecular phylogenetic analyses, morphometrics, and scanning ... -
Species data for understanding biodiversity dynamics: The what, where and when of species occurrence data collection
(Peer reviewed; Journal article, 2021)1. The availability and quantity of observational species occurrence records have greatly increased due to technological advancements and the rise of online portals, such as the Global Biodiversity Information Facility ... -
Species delimitation analyses of NE Atlantic Chaetozone (Annelida, Cirratulidae) reveals hidden diversity among a common and abundant marine annelid
(Peer reviewed; Journal article, 2020)The polychaetes of the family Cirratulidae (Annelida) are common inhabitants in continental shelf benthic environments and considered an important group of organisms in environmental monitoring surveys. The family represents ... -
Species delimitation and phylogenetic relationships of the Prionospio complex (Annelida, Spionidae) in the Northeast Atlantic
(Peer reviewed; Journal article, 2024)The Prionospio complex comprises the most diverse and complex group within the polychaete family Spionidae. The phylogenetic relationships within the group are still poorly understood, and the generic breakdown is unstable. ... -
Species delimitation and phylogeny of Doto (Nudibranchia: Dotidae) from the Northeast Atlantic, with a discussion on food specialization
(Peer reviewed; Journal article, 2021)The nudibranch genus Doto is taxonomically problematic in particular, and some species are described on the notion of strict monophagy. Here we perform species delimitation on NE Atlantic species, as well as placing them ... -
Species delimitation in Amblyosyllis (Annelida, Syllidae)
(Journal article; Peer reviewed, 2019)Amblyosyllis is a worldwide distributed group of annelids mainly found in coastal environments. It is well known among the polychaete specialists mostly because of its notable beauty, showing bright colourful patterns and ... -
Species delimitation in northern European water scavenger beetles of the genus Hydrobius (Coleoptera, Hydrophilidae)
(Journal article; Peer reviewed, 2016)The chiefly Holarctic Hydrobius species complex (Coleoptera, Hydrophilidae) currently consists of H. arcticus Kuwert, 1890, and three morphological variants of H. fuscipes (Linnaeus, 1758): var. fuscipes, var. rottenbergii ... -
Species-specific coral calcification responses to the extreme environment of the southern Persian Gulf
(Peer reviewed; Journal article, 2018)Sustained accretion of calcium carbonate (mostly by scleractinian corals) is fundamental for maintaining the structure and function of coral reef ecosystems, but may be greatly constrained by extreme and rapidly changing ... -
Sphaerodoridae (Annelida) of the deep northwestern Atlantic, including remarkable new species of Euritmia and sphaerephesia
(Journal article; Peer reviewed, 2016)Sphaerodoridae (Annelida) is a seeming uncommon and minimally diverse group of polychaetes in the northwestern Atlantic, with only seven species reported from the United States, and none from the eastern coast of Canada, ... -
Sphagnum divinum (sp. nov.) and S. medium Limpr. and their relationship to S. magellanicum Brid.
(Journal article; Peer reviewed, 2018)Sphagnum magellanicum has been viewed as being a predominantly circumpolar species in the northern hemisphere, but it occurs in the southern hemisphere and was originally described from the southern parts of Chile. It is ... -
Sphagnum incundum a new species in Sphagnum subg. Acutifolia (Sphagnaceae) from boreal and arctic regions of North America
(Journal article; Peer reviewed, 2018)We describe Sphagnum incundum in Sphagnum subg. Acutifolia (Sphagnaceae, Bryophyta). We used both molecular and morphological methods to describe the new species. Molecular relationships with closely related species were ... -
Sphagnum magniporosum (Sphagnaceae, subgenus Subsecunda) a new peatmoss species from Venezuela
(Journal article; Peer reviewed, 2022)We describe Sphagnum magniporosum sp. nov. in Sphagnum subgen. Subsecunda (Sphagnaceae) Bryophyta. The new species is described and characterized using morphological methods. The description is based on qualitative examination ... -
Sphagnum Xlydiae, the first allotriploid peatmoss in the Northern hemisphere
(Journal article; Peer reviewed, 2019)In plants, hybridization between interspecific taxa leading to chromosome doubling seems to happen regularly and may be an important driver of speciation. Allopolyploid species often have morphological traits from both ... -
