Colonization of the Beaufort Coastal Plain by Beaver (<i>Castor canadensis</i>): A Response to Shrubification of the Tundra?

The Canadian Field-Naturalist, 2017
A consequence of rapid global warming has been the shrubification (increase in shrub abundance, cover, and biomass) of arctic and alpine tundra ecosystems. Shrubification is likely a key driver of predicted and observed changes in the biodiversity of the Arctic.

Different Dispersal Rates and Declining Climate Suitability Shape Future Vegetation Compositions Across the Arctic

Journal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim We investigate how species‐specific dispersal abilities might influence future Arctic plant distributions and large‐scale dynamics at the boreal forest–tundra boundary until 2100. Location Circumpolar terrestrial Arctic (boreal forest, taiga and tundra). Taxon 1550 plant species.

Rhizosphere bacteria and fungi are differentially structured by host plants, soil mineralogy, and ectomycorrhizal communities in the Alaskan Tundra

Arctic Science
The rhizosphere contains diverse groups of bacteria and fungi living near plant roots and mycorrhizal hyphae whose composition and function are key drivers of ecosystem and biogeochemical processes.

Predicting Alder shrub expansion in Sub-Arctic Alaska using machine learning, satellite data, and environmental variables [PDF]

The wider Fairbanks area, a sub-Arctic region of Alaska, USA, is home to a variety of alpine, oroarctic tundra that is being impacted by climate warming.

Exploring the Effects of Shrubification on the Community-level Flowering Phenology and Reproductive Success of Alpine Plants [PDF]

, 2022
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 ...

Ancient DNA and lipid biomarkers quantify the climate sensitivity of highland shrubification in Iceland

Future changes in high latitude shrubification are expected to lead to changes in ecosystem structure and positive climate feedbacks, but the rates and elevational range of shrubification are still poorly constrained. Using a sediment record from a small lake in Iceland’s eastern highlands (422 m asl), we merge a sedimentary ancient DNA (sedaDNA ...

Remotely Piloted Aircraft Systems (RPAS) for Monitoring Archaeological Sites in Nunavik in the Face of a Changing Climate

Canadian Journal of Remote Sensing
Over the last century, remote sensing has proven effective in recognizing and studying cultural heritage in various geographic and chronological contexts, and the use of Remotely Piloted Aircraft Systems (RPAS) has become an integral part of ...

Hyperspectral and multispectral satellite data analysis of nitrogen in grazed and ungrazed tundra in Långfjället, Sweden [PDF]

, 2023
Reindeer are a keystone species in the circumpolar north, where they hold great cultural and ecological importance. Continued climate change threatens the long-term sustainability of reindeer husbandry.
