We provide the first documentation of tectonic deformation resulting from a volcanic eruption on the island of Jan Mayen. Vertical displacement of about 14 m southwest of the stratovolcano Beerenberg is associated with an ...

Six species of Ophelina Ørsted, 1843 have been identified in an extensive material covering 145 localities from 575 to 3900 m depth in the Nordic Seas. Ophelina opisthobranchiata Wirén, 1901 and O. helgolandiae Augener, ...

In Greenland, Atlantic salmon are known to reproduce in only one river, the Kapisillit River. Little is known about the population characteristics or the relationship to other salmon populations across the species range, ...

Long-term demographic data are needed for detailed viability analyses of populations threatened by climate change, but the infeasibility of obtaining such data makes it urgent to assess whether demographic responses to ...

Whole-genome sequencing projects are increasingly populating the tree of life and characterizing biodiversity1,2,3,4. Sparse taxon sampling has previously been proposed to confound phylogenetic inference5, and captures ...

Understanding and predicting large-scale ecological responses to global environmental change requires comparative studies across geographic scales with coordinated efforts and standardized methodologies. We designed, ...

Background Sabellarids, also known as honeycomb or sandcastle worms, when building their tubes, produce chemical signals (free fatty acids) that are responsible for larval settlement and the formation of three-dimensional ...
