TL;DR: This article used repeat photography, long-term ecological monitoring and dendrochronology to document shrub expansion in arctic, high-latitude and alpine tundra.

TL;DR: In this article, the authors analyzed circumpolar data from 37 Arctic and alpine sites in 9 countries, including 25 species, and ∼42,000 annual growth records from 1,821 individuals, and demonstrated that the sensitivity of shrub growth to climate was heterogeneous, with European sites showing greater summer temperature sensitivity than North American sites, and higher at sites with greater soil moisture and for taller shrubs (for example, alders and willows) growing at their northern or upper elevational range edges.

TL;DR: The Tundra Trait Team (TTT) database as discussed by the authors includes field-based measurements of key traits related to plant form and function at multiple sites across the tundra biome.

TL;DR: It is shown that known plant trait relationships extend to the tundra biomes and exhibit the same two dimensions of variation detected at the global scale, informing prediction of plant community change in a warming world.

TL;DR: In this paper, the authors summarize the findings of 191 new and archived interviews addressing the continued relationships of Inuit to berries in the Canadian territories of Nunavut, Nunavik, and Nunatsiavut.
