Phytophagous mites (Acari: Eriophyoidea) recorded from Svalbard, including the description of a new species

Eriophyoid mites (Eriophyoidea) are minute phytophagous mites with great economic importance and great invasive potential. In spite of their demonstrated impact on ecosystem functions, knowledge of eriophyoid mite fauna in the Arctic is lacking. To date, only eight eriophyoid mite species have been recorded from the entire region north of the Arctic Circle. The Svalbard archipelago ...

Tardigrada of the Revdalen (Spitsbergen) with the descriptions of two new species: Bryodelphax parvuspolaris (Heterotardigrada) and Isohypsibius coulsoni (Eutardigrada)

Despite a century long history of research, tardigrade fauna of the Svalbard Archipelago remains poorly known. In order to deepen our knowledge of tardigrade biodiversity in the Arctic, we collected forty-one moss and lichen samples from the Revdalen and on the south-east slopes of the Rotjesfjellet (Spitsbergen, Svalbard Archipelago) in June 2010. In these samples, twenty-five ...
