Abstract A 24,000-year record of plant community dynamics, based on pollen and ancient
DNA from the sediments (sedaDNA) of Lake Bolshoye Shchuchye in the Polar Ural …

Arctic terrestrial ecosystems are generally considered to be species poor, fragile and often
isolated. Nonetheless, their intricate complexity, especially that of the invertebrate …

Woody shrubs have increased in biomass and expanded into new areas throughout the Pan-
Arctic tundra biome in recent decades, which has been linked to a biome-wide observed …

Aim The 'centre–periphery hypothesis'(CPH) predicts that species performance (genetics,
physiology, morphology, demography) will decline gradually from the centre towards the …

Aim Species' biogeographical patterns are already being altered by climate change. Here,
we provide predictions of the impacts of a changing climate on species' geographical ranges …

According to some treatises, arctic and alpine sub‐biomes are ecologically similar, whereas
others find them highly dissimilar. Most peculiarly, large areas of northern tundra highlands …

High Arctic environments are particularly sensitive to climate changes, but retrieval of
paleoecological data is challenging due to low productivity and biomass. At the same time …

Boreal and cool temperate forests are the major land cover of northern Eurasia, and
information about continental‐scale genetic structure and past demographic history of forest …

Abstract Background and Aims Betula L.(birch) is a genus of approx. 60 species, subspecies
or varieties with a wide distribution in the northern hemisphere, of ecological and economic …

Boreal species were repeatedly exposed to ice ages and went through cycles of contraction
and expansion while sister species alternated periods of contact and isolation. The resulting …
