Sea ice is a key factor for the functioning and services provided by polar marine ecosystems.
However, ecosystem responses to sea-ice loss are largely unknown because time-series …

Arctic and alpine aquatic ecosystems are changing rapidly under recent global warming,
threatening water resources by diminishing trophic status and changing biotic composition …

This study is based on multiproxy data gained from a 14 C-dated 6.5 m long sediment core
and a 210 Pb-dated 23 cm short core retrieved from Lake Rauchuagytgyn in Chukotka …

Woody plants are expanding into the Arctic in response to the warming climate. The impact
on arctic plant communities is not well understood due to the limited knowledge about plant …

Lakes act as important sinks for inorganic and organic sediment components. However,
investigations of sedimentary carbon budgets within glacial lakes are currently absent from …

Millennial-scale climate change history in eastern Siberia and relationships between diatom
diversity, paleoclimate, and sediment-geochemical lake system trajectories are still poorly …

Only a few palaeo-records extend beyond the Holocene in Yakutia, eastern Siberia, since
most of the lakes in the region are of Holocene thermokarst origin. Thus, we have a poor …

The fluctuations of the forest/tundra boundary are among the most significant indicators of
climate change in the Arctic. The most reliable information regarding the historical position of …

Age–depth relationships are the key elements in paleoenvironmental studies to place proxy
measurements into a temporal context. However, potential influencing factors of the …

Mining operations in the Enmynveem valley, northeastern Siberia, exposed a well-
preserved right hind leg of Mammuthus primigenius (woolly mammoth), dated to ca. 37,500 …
