Mycorrhizal symbioses and Arctic shrubification. [PDF]
Abstract A unifying feature of the deciduous and evergreen shrubs contributing to the greening of the Arctic landmass—the process known as shrubification—is that their roots consistently form ectomycorrhizal or ericoid mycorrhizal symbioses with soil fungi.

Alpine Shrubification: Juniper Encroachment into Tundra in the Ural Mountains
Snow cover is one of the most important factors affecting the regeneration and growth of shrubs in cold arctic and alpine ecosystems. In many of these cold regions, climate change in the last century is manifested not only in a rapid rise of temperature, but also in an increase in winter precipitation. For instance, in the Ural Mountains, winter turned

Stream Temperature Response to Increased Shading Due To Riparian Shrubification in Northern Latitudes [PDF]
Abstract Global warming is causing rapid and profound impacts on northern ecosystems. Shifting precipitation, permafrost thaw, and rapid shrub advance into tundra environments are combining to alter stream temperature in uncertain ways.

Reindeer grazing controls willows but has only minor effects on plant communities in Fennoscandian oroarctic mires [PDF]
Shrubification of arctic tundra is a well-recognized phenomenon, and it can be particularly rapid in moist habitats. Reindeer grazing can inhibit shrubification, but grazing impacts on mire vegetation have been overlooked.

Microclimatic comparison of lichen heaths and shrubs: shrubification generates atmospheric heating but subsurface cooling during the growing season [PDF]
Lichen heaths are declining in abundance in alpine and Arctic areas partly due to an increasing competition with shrubs. This shift in vegetation types might have important consequences for the microclimate and climate on a larger scale.

Exploring the Effects of Shrubification on the Community-level Flowering Phenology and Reproductive Success of Alpine Plants [PDF]
Climate-change induced alterations in environmental conditions in the alpine tundra has led to the expansion of woody shrubs, known as “shrubification.” Shrubification is thought to change microclimatic conditions, potentially leading to ...

Can large animals direct the fate of the vast arctic soil carbon reserves – a review [PDF]
Arctic areas store vast soil carbon reserves that are highly sensitive to be released into the atmosphere due to a warming climate. Large arctic herbivores may shape this sensitivity, but owing to high spatial and temporal variation in their ecosystem ...
