Forty six species of invertebrate were collected from the manure enriched imported soils below the abandoned cow sheds in the Russian mining town of Barentsburg, Svalbard. Of these, 11 (24 %) were new records for Svalbard, including Collembola, gamasid mites, Enchytraeidae and the first identified Lumbricidae. Many of the new records are species not frequently observed in the Arctic. It is hypothesized that these species arrived with the chernozem soils imported to Barentsburg for the greenhouses from central or southern European Russia, or with livestock. The observations presented here are the first records of human invertebrate introductions establishing in Svalbard outside of dwellings. It is not believed that the majority of new species records described present an immediate threat to the ecology of Svalbard but they may, especially Deuteraphorura variabilis, establish in the nutrient enriched floral communities beneath bird cliffs characteristic of Svalbard. © 2012 Springer Science+Business Media B.V.

The terrestrial environment of the High Arctic consists of a mosaic of habitat types, both natural and anthropogenic. At the abandoned coal mining town of Pyramiden, Svalbard, topsoil was imported from southern European Russia. This, and further industrial disturbance in the town, offers new opportunities for the native invertebrate fauna, but may also introduce alien, potentially invasive, species. Few studies have examined anthropogenic habitats in the High Arctic. But increasing activity, including industry and tourism, requires an understanding of the responses of the Arctic to such pressures. The microarthropod communities observed in the settlement were substantially different from the natural tundra. In the settlement, nine species of mesostigmatid mite occurred (three new records for Svalbard; Dendrolaelaps foveolatus) and two additional not identified to species (Halolaelaps sp., Arctoseius sp.), 26 species of Collembola (12 not seen in the natural tundra close to Pyramiden) and two new records (Thalassaphorura debilis and Desoria tigrina), but only five Oribatida. This is set against 8, 20 and 24 species respectively for Mesostigmata, Oribatida and Collembola from natural tundra in the vicinity. The imported soils remain to be yet fully exploited by the native microarthropod fauna. Taxa disparities may result from differential mortality during collection and shipping of the soil, and subsequent colonisation. While none of the introduced species appear to be invasive, responses to climate change scenarios are difficult to project. Understanding of alien species and the timespans required for colonization by native faunas are of importance for remediation and reclamation projects in polar regions. © 2015, Springer Science+Business Media Dordrecht.

The terrestrial environment of the High Arctic consists of a mosaic of habitat types. In addition to the natural habitat diversity, various human-influenced types may occur. For the resident invertebrate fauna, these anthropogenic habitats may be either unusually favourable or detrimental. In the town of Barentsburg, Svalbard, soils were imported for the greenhouses from southern Russia. These soils were subsequently discarded outside the greenhouses and have become augmented with manure from the cowsheds. Both the greenhouse and the cowsheds are now derelict. This site represents an unusually nutrient-rich location with considerable development of organic soils, in stark contrast to the naturally forming organic soils in Svalbard, which are typically thin and nutrient poor. Few previous studies have examined the soil invertebrate communities of human-disturbed or -created habitats in the Arctic. In an often nutrient-poor terrestrial environment, it is unclear how the invertebrate fauna will react to such nutrient enhancement. In these soils, 46 species of invertebrates were determined. Eleven species have not been recorded from other habitats in Svalbard and are hence likely to have been introduced. The native species assemblage in the anthropogenic soils was not atypical for many natural sites in Svalbard. Despite the enriched organic soils and highly ameliorated winter temperature conditions, the soil invertebrate fauna biodiversity does not appear to be enhanced beyond the presence of certain probably introduced species. © 2013 S.J.

The Collembola, Araneae and gamasid mite fauna from the vicinity of Kinnvika on the island of Nordaustlandet in the Svalbard archipelago are described. Few records of the invertebrate fauna from this remote and climatically extreme region exist. Twenty-four species of Collembola were identified, of which three were new records for Nordaustlandet. None were new records for Svalbard. In addition, seven species of Araneae, three of which were new records for Nordaustlandet, and five species of gamasid mite, all new to Nordaustlandet, were collected. All invertebrates collected were already known from locations on the west coast of Spitsbergen. These records supplement the scarce current terrestrial invertebrate data for this region and contribute towards the baseline data for this region proposed to become an Arctic environmental reference area. © The authors 2011.

A new species and genus, Skadisotoma inpericulosa, is described from south-eastern Australia. It possesses some characters that are found in Tomoceridae, such as a long cylindrical dens that is medially bent and a mucro with at least six teeth of different sizes and three setae but in other characters it resembles an isotomid. In this it shows similarities to the Boreal genus Mucronia Fjellberg, but differs from it in the possession of spines on the dens and in some chaetotaxic characters. Copyright © 2015 Magnolia Press.
