High northern latitude changes with Arctic amplification across a latitudinal forest gradient
suggest a shift towards an increased presence of trees and shrubs. The persistence of …

The transition from forest to tundra in Arctic and alpine regions, frequently referred to as
treeline, has preoccupied biogeographers and ecologists for more than a century. It is widely …

Ongoing encroachment is driving recent alpine shrubline dynamics globally, but the role of
shrub-shrub interactions in sha** shrublines and their relationships with stem density …

Significant treeline advance can only occur with successful establishment, growth, and
survival of new seedlings. Several studies have examined microsite factors at single …

Stereogrammetry applied to globally available high resolution spaceborne imagery (HRSI;<
5 m spatial resolution) yields fine-scaled digital surface models (DSMs) of elevation. These …

Aims Several mechanistic hypotheses have been developed to explain the existence of
alpine treelines worldwide. The reproduction limitation hypothesis (RLH) postulates that …

Soil enzymes play an important role in nutrient biogeochemical cycling in terrestrial
ecosystems. Previous studies have emphasized the variability of soil enzyme activities and …

Surface elevation estimates from high resolution spaceborne image (HRSI)
stereogrammetry are used to examine fine-scaled structure of boreal forest canopies. These …

The arctic forest–tundra ecotone (FTE), which links species communities of the boreal forest
with those of the arctic tundra, is expected to respond swiftly to climate change with a …

Current configurations of forest structure at the cold edge of the boreal may help understand
the future of ecosystem functioning in high northern latitudes. The circumpolar biome …
