Syngenetically frozen deposits that are fine-grained and ice-rich are widely distributed in
lowlands of northeastern Siberia, Alaska and northwestern Canada. These late Pleistocene …

While there are numerous hypotheses concerning glacial–interglacial environmental and
climatic regime shifts in the Arctic Ocean, a holistic view on the Northern Hemisphere's late …

The large amounts of soil organic matter (SOM) in permafrost-affected soils are prone to
increased microbial decomposition in a warming climate. The environmental parameters …

Observations of coastline retreat using contemporary very high resolution satellite and
historical aerial imagery were compared to measurements of open water fraction, summer …

Uncertainty about the geological processes that deposited syngenetically frozen ice‐rich silt
(yedoma) across hundreds of thousands of square kilometres in central and northern Siberia …

Pronounced glacial and interglacial climate cycles characterized northern ecosystems
during the Pleistocene. Our understanding of the resultant community transformations and …

As the main external driver, environmental changes largely predetermine human population
distribution, especially in the Arctic, where environmental conditions were often too extreme …

Atmospheric concentrations of carbon dioxide increased between the Last Glacial Maximum
(LGM, around 21,000 years ago) and the preindustrial era. It is thought that the evolution of …

Ice wedges are a characteristic feature of northern permafrost landscapes and grow mainly
by snowmelt that refreezes in thermal contraction cracks that open in winter. In high latitudes …

Although sedimentary ancient DNA (sed aDNA) has been increasingly used to study
paleoecological dynamics, the approach has rarely been compared with the traditional …
