Invertebrates in the gradient of different age soils under a birdcliff at the Grønfjord Area (Svalbard, Arctic)

The aim of this study was a preliminary analysis of the distribution of microarthropods (Oribatida, Collembola) and herpetobiontic invertebrates (Aranei, Coleoptera) in soils of different ages under a seabird colony in the vicinity of the Barentsburg settlement (Svalbard). Two transects were establi...
