The gut microbiota structure reflects both a host phylogenetic history and a signature of adaptation to the host ecological, mainly trophic niches. African cichlid fishes, with their array of closely related species that ...

Measurements of total ozone column and effective cloud transmittance have been performed since 1995 at the three Norwegian sites Oslo/Kjeller, Andøya/Tromsø, and in Ny-Ålesund (Svalbard). These sites are a subset of nine ...

The monogenean freshwater parasite Gyrodactylus salaris Malmberg, 1957 is endemic to Atlantic salmon (Salmo salar) east of the Baltic Sea, but has spread outside this area via transport and stocking of fish. In Norway and ...

Here, we document a detailed characterisation of two zircon gemstones, GZ7 and GZ8. Both stones had the same mass at 19.2 carats (3.84 g) each; both came from placer deposits in the Ratnapura district, Sri Lanka. The U‐Pb ...

In cortex, the local field potential (LFP) is thought to mainly stem from correlated synaptic input to populations of geometrically aligned neurons. Computer models of single cortical pyramidal neurons showed that subthreshold ...

Background Although some mechanisms of habitat adaptation of conspecific populations have been recently elucidated, the evolution of female preference has rarely been addressed as a force driving habitat ...

Breeding habitat-choice in two closely related species of passerines, Great Tit (Parus major) and Blue Tit (Cyanistes caereleus) was studied to reveal if their habitat preferences primarily is a hereditary trait, or if ...

Habitat fragmentation has been suggested to be responsible for major genetic differentiations in a range of marine organisms. In this study, we combined genetic data and environmental information to unravel the relative ...

The red deer (Cervus elaphus) are among the most important game species in Norway, with a tenfold increase in harvest over the last few decades. Despite its importance, information regarding red deer habitat selection is ...
