The terrestrial and freshwater invertebrate biodiversity of the archipelagoes of the Barents Sea; Svalbard, Franz Josef Land and Novaya Zemlya
Arctic terrestrial ecosystems are generally considered to be species poor, fragile and often isolated. Nonetheless, their intricate complexity, especially that of the invertebrate component, isExpand
The ratio of fungi and bacteria in the biomass of different types of soil determined by selective inhibition
Soils under study have shown the predominant contribution of fungi and bacteria to substrate-induced respiration (SIR) with the help of antibiotics, and the lower layers of soddy-podzolic and grey forest soils showed a decrease in the fungal and increase in the bacterial component in the total SIR.

The fauna of free-living mites (Acari) of Greenland
When compiling The Greenland Entomofauna, the mite collections kept at the Zoological Museum of the University of Copenhagen were processed and an analysis of the type material preserved in the Museum allowed three taxa of Mesostigmata to be synonymized. Expand
Neutron diffraction study of the chiral magnet MnGe
Uncollinear magnets yield the possibility of couplingelectric and magnetic degrees of freedom, a keyExpand
Competing ferromagnetic and antiferromagnetic interactions in Laves hydrides
Abstract.We studied the influence of Fe substitution on the crystal and magnetic structure of the Laves hydrides Y(Mn1-xFex)2H4.3, by powder neutron diffraction. For x<0.1, we observed long-rangeExpand
A New Genus and Three New Species of the Mite Family Arctacaridae ( Parasitiformes , Mesostigmata ) from North America
A new genus Proarctacarus and three new species, P. canadensis (Rocky Mountains, Alberta, Canada), and P. johnstoni (Rocky Mountains, Idaho, Utah, USA), and P. oregonensis (Coast Ranges, Oregon,Expand
The fauna of free-living gamasid mites (Parasitiformes, Mesostigmata) in the northern Taiga: an analysis of the zonal specificity
It is in the taiga that the family Ascidae becomes the most diverse among Mesostigmata, and in the tundra zone, this tendency is more pronounced, and this family constitutes 70–83% of species in local faunas, represented mainly by the genus Arctoseius. Expand
Effects of Cushion Plants on High-Altitude Soil Microarthropod Communities: Cushions Increase Abundance and Diversity of Mites (Acari), but not Springtails (Collembola)
The results show that cushion plants are a key in maintaining the biodiversity of soil microarthropods in the high alpine, and maintain higher moisture and organic matter content in the soil, provide productive and structurally complex habitat, and mitigate disturbance. Expand
Beetles (Coleoptera) in polar deserts of the Severnaya Zemlya Archipelago
The first report on the coleopteran fauna in the polar desert zone is reported, and Micralymma brevilingue should be considered as the most cold-tolerant beetle species of the Northern Hemisphere. Expand
