Arctic East Siberia had a lower latitude in the Pleistocene.

Remains of mammoths in Arctic East Siberia, where there is not sufficient sunlight over the year for the growth of the plants on which these animals feed, indicate that the latitude of this region was lower before the end of the Pleistocene than now. Reconstructing this geographic pole shift, we introduce a massive object, which moved in an extremely eccentric orbit and was hot from tidal work ...

Ice Complex formation in arctic East Siberia during the MIS3 Interstadial

A continuous 15 m long sequence of Ice Complex permafrost (Yedoma) exposed in a thermo-cirque at the southern coast of Bol’shoy Lyakhovsky Island (New Siberian Archipelago, Dmitry Laptev Strait) was studied to reconstruct past landscape and environmental dynamics. The sequence accumulated during the Marine Isotope Stage 3 (MIS3) Interstadial between >49 and 29 ka BP in an ice-wedge polygon. The...

Breeding Biology of the Eurasian Nuthatch in Northeastern Siberia

AnsTn.Kr. -The breeding biology of Eurasian Nuthatches (Sitta europaea asiatica) was studied in 1986-1990 in two habitats, riparian and upland forests, in the Magadan region, northeastern Siberia. Clutch sizes and breeding success averaged 6.49 eggs and 57.5%, respectively, and varied among years. Habitat influenced clutch size but not numbers of young fledged from successful nests. Within seas...

Of Chicks of Arctic-breeding Shorebirds

l. The heat-transfer characteristics of young and adults of several arctic-breeding shorebirds were examined. Heated. skin-covered metal casts were used for measurements difficult to perform on live birds. 2. Heat transfer coefficients are high in small chicks, but decrease rapidly with age. Both heat transfer coefficients and body resistances to heat flow (i.e. insulation) are linearly related...

East Siberia had a lower latitude in the Pleistocene

In Arctic East Siberia many remains of mammoths have been found. In this region there is not sufficient sunlight over the year to allow for the growth of the plants on which these animals feed. Consequently the latitude of these regions must have been lower before the end of the Pleistocene than at present. It is a challenge to reconstruct this geographic shift of the poles in a manner compatib...
