Wetlands in the Pleistocene Steppe-Tundra Landscapes of Beringia, Their Insects, and the Role of Aeolian Sedimentation

Analysis of the database Beringian subfossil insect assemblages showed a relatively low role aquatic, riparian, and wetland species insects with hard exoskeleton in Pleistocene communities an increase their proportions taxonomic diversity Holocene. Aquatic were represented all types geological deposits some paleosols, but varied different depositional environments. Poor representation aquatic lack freshwater invertebrates Late ice-rich Beringia called Siberian Yedoma or Yukon Muck attest to predominantly aeolian origin this phenomenon.
