Tree vegetation of the forest-tundra ecotone in the Western Sayan mountains and climatic trends
TLDR
In this paper, the reproduction of the Siberian stone pine (Pinus sibirica), including radial and apical tree increments, the age structure of stands, the amount of young growth, and its distribution along an altitudinal gradient, have been studied in the forest-tundra ecotone of the Western Sayan.Abstract:
Parameters of reproduction of the Siberian stone pine (Pinus sibirica), including radial and apical tree increments, the age structure of stands, the amount of young growth, and its distribution along an altitudinal gradient, have been studied in the forest-tundra ecotone of the Western Sayan. The results show that, over the past 30 years, P. sibirica undergrowth has expanded to the mountain tundra belt, the apical and radial tree increments and stand density have increased, and the life form of many P. sibirica plants has changed from prostrate to erect (single-or multistemmed). These changes correlate with the dynamics of summer temperatures and monthly (in May and June) and annual precipitation. The rise of summer temperatures by 1°C promotes the expansion of P. sibirica undergrowth for approximately 150 m up the altitudinal gradient.read more

Transitions in Arctic ecosystems: Ecological implications of a changing hydrological regime
Frederick J. Wrona,Margareta Johansson,Joseph M. Culp,Alan Jenkins,Johanna Mård,Isla H. Myers-Smith,Terry D. Prowse,Warwick F. Vincent,Philip A. Wookey +8 more
TL;DR: In this article, the terrestrial and freshwater ecology component of the Arctic Freshwater Synthesis is reviewed and recommended enhanced coordinated circumpolar research and monitoring efforts to improve quantification and prediction of how an altered hydrological regime influences local, regional, and circumpheric-level responses in terrestrial and freshwater systems.

TL;DR: The authors' finding of mixed EG trends and no general rules controlling EG dynamics poses challenges for mitigating possible adverse impacts of climate change on mountainous biological diversity and ecosystem services.

Response of Pinus sibirica and Larix sibirica to climate change in southern Siberian alpine forest–tundra ecotone
TL;DR: In this article, the warmer temperatures observed in central Siberia over the past three decades appear to have had a noticeable effect on growth of Siberian pine and larch (Larix sibirica Ledeb.) in the south Siberian Mountain forest-tundra ecotone.

Spatial distribution and temporal dynamics of high-elevation forest stands in southern Siberia.
TL;DR: In this article, the authors evaluated the hypothesis that topographic features of high-elevation mountain environments govern spatial distribution and climate-driven dynamics of the forest and found that the spatial patterns in mountain forests are anisotropic with respect to azimuth, slope steepness and elevation.

Tree and forest functioning in response to global warming
TL;DR: This review focuses on tree and forest responses at boreal and temperate latitudes, ranging from the cellular to the ecosystem level, and management is critical for a positive response of forest growth to a warmer climate.

Rapid recent range-margin rise of tree and shrub species in the Swedish Scandes
TL;DR: The present results suggest a shift in reproduction and a significant break in the late-Holocene vegetation history of tree and shrub species at a site in the Swedish Scandes.
