Delayed postglacial colonization of Betula in Iceland and the circum North Atlantic [PDF]
eLife, 2023 As the Arctic continues to warm, woody shrubs are expected to expand northward. This process, known as ‘shrubification,’ has important implications for regional biodiversity, food web structure, and high-latitude temperature amplification.

Arctic tundra shrubification: a review of mechanisms and impacts on ecosystem carbon balance [PDF]
Environmental Research Letters, 2021 Vegetation composition shifts, and in particular, shrub expansion across the Arctic tundra are some of the most important and widely observed responses of high-latitude ecosystems to rapid climate warming.

Holocene chloroplast genetic variation of shrubs (Alnus alnobetula, Betula nana, Salix sp.) at the siberian tundra‐taiga ecotone inferred from modern chloroplast genome assembly and sedimentary ancient DNA analyses [PDF]
Ecology and Evolution, 2021 Climate warming alters plant composition and population dynamics of arctic ecosystems. In particular, an increase in relative abundance and cover of deciduous shrub species (shrubification) has been recorded. We inferred genetic variation of common shrub

Topography and functional traits shape the distribution of key shrub plant functional types in low-Arctic tundra [PDF]
Frontiers in Plant ScienceThe expansion of shrubs in the Arctic tundra fundamentally modifies land-atmosphere interactions. However, it remains unclear how shrub distribution and expansion differ across key species due to challenges with discriminating tundra plant species at ...

Decreasing carbon allocation belowground in alpine meadow soils by shrubification [PDF]
GeodermaDistribution of shrubs expanding in grasslands – shrubification – is ongoing worldwide in grasslands and is common on the Qinghai–Tibetan Plateau (QTP). But the consequences of shrubification for plant carbon (C) input and fate in soil are unclear.

Different effects of alpine woody plant expansion on domestic and wild ungulates. [PDF]
Glob Chang Biol, 2019 Changes in land-use and climate affect the distribution and diversity of plant and animal species at different spatiotemporal scales. The extent to which species-specific phenotypic plasticity and biotic interactions mediate organismal adaptation to ...

Reindeer grazing controls willows but has only minor effects on plant communities in Fennoscandian oroarctic mires [PDF]
Arctic, Antarctic, and Alpine Research, 2019 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.

Can large animals direct the fate of the vast arctic soil carbon reserves – a review [PDF]
Environmental Research CommunicationsArctic 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 ...

A pioneering pest: the winter moth (Operophtera brumata) is expanding its outbreak range into Low Arctic shrub tundra [PDF]
Arctic Science, 2022 Climate warming allows generalist boreal consumers to expand into Arctic ecosystems. We present experimental and observational field data showing that a generalist boreal insect pest—the winter moth (Operophtera brumata Linnaeus, 1758)—is expanding its ...

Bilberry Expansion in the Changing Subalpine Belt [PDF]
PlantsBilberry (Vaccinium myrtillus L.) expansion in subalpine and alpine ecosystems is increasing due to climate change and reduced land management. This review examines bilberry traits, environmental responses, and ecosystem impacts.
