The biogeography of Iceland is controversial. Some authors believe that all Icelandic life originated after postglacial dispersal events (tabula rasa hypothesis), but others assume that some organisms survived the last glaciation in ice-free refugia. To extend existing knowledge of the freshwater biogeography of Iceland, we used a snail species, Radix(More)
Freshwater invertebrates are able to develop specific ecological adaptations that enable them to successfully inhabit an extreme environment. We investigated the brooding bivalve of Pisidium casertanum in Talatinskoe Lake, Vaigach Island, Arctic Russia. Here, quantitative surveys were conducted, with the collection and dissections of 765 molluscs, on the(More)
Although a recent series of studies has examined the phylogeography and diversity of Arctic invertebrates related to the glacial history on a pan-Arctic scale, large gaps remain in the knowledge on the origin, dispersal and biogeography of freshwater mollusks in the Russian Arctic. In samples from two lakes on Vaigach Island, Arctic European Russia, we(More)
The freshwater pearl mussel family Margaritiferidae includes 13 extant species, which are all listed by IUCN as endangered or vulnerable taxa. In this study, an extensive spatial sampling of Margaritifera spp. across the Russian Far East (Amur Basin, Kamchatka Peninsula, Kurile Archipelago and Sakhalin Island) was conducted for a revision of their taxonomy(More)
