Tundra shrubification and tree-line advance amplify arctic climate warming: results from an individual-based dynamic vegetation model [PDF]
Environmental Research Letters, 2013 One major challenge to the improvement of regional climate scenarios for the northern high latitudes is to understand land surface feedbacks associated with vegetation shifts and ecosystem biogeochemical cycling.

Arctic shrubification mediates the impacts of warming climate on changes to tundra vegetation
Environmental Research Letters, 2016 Climate change has been observed to expand distributions of woody plants in many areas of arctic and alpine environments—a phenomenon called shrubification.

Microclimatic comparison of lichen heaths and shrubs: shrubification generates atmospheric heating but subsurface cooling during the growing season [PDF]
Biogeosciences, 2021 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.

Simulated rhizosphere deposits induce microbial N-mining that may accelerate shrubification in the subarctic [PDF]
Ecology, 2020 Climate change is exposing high-latitude systems to warming and a shift towards more shrub-dominated plant communities, resulting in increased leaf-litter inputs at the soil surface, and more labile root-derived organic matter (OM) input in the soil ...

Can reindeer husbandry management slow down the shrubification of the Arctic? [PDF]
Journal of Environmental Management, 2020 Rapid climate change is threatening the stability and functioning of Arctic ecosystems. As the Arctic warms, shrubs have been widely observed to expand, which has potentially serious consequences for global climate regulation and for the ecological ...

Mycorrhizal symbioses and Arctic shrubification [PDF]
Sustainable MicrobiologyA 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. Here,

Arctic tundra shrubification can obscure increasing levels of soil erosion in NDVI assessments of land cover derived from satellite imagery [PDF]
Remote Sensing of EnvironmentThis research was supported by the St Andrews World Leading Scholarship.Monitoring soil erosion in the Arctic tundra is complicated by the highly fragmentated nature of the landscape and the limited spatial resolution of even high-resolution satellite ...

Molecular Footprints of Quaternary Climate Fluctuations in the Circumpolar Tundra Shrub Dwarf Birch. [PDF]
Mol EcolThe Arctic tundra biome is undergoing rapid shrub expansion (‘shrubification’) in response to anthropogenic climate change. During the previous ~2.6 million years, glacial cycles caused substantial shifts in Arctic vegetation, leading to changes in ...

Patterns of free amino acids in tundra soils reflect mycorrhizal type, shrubification, and warming. [PDF]
Mycorrhiza, 2022 AbstractThe soil nitrogen (N) cycle in cold terrestrial ecosystems is slow and organically bound N is an important source of N for plants in these ecosystems. Many plant species can take up free amino acids from these infertile soils, either directly or indirectly via their mycorrhizal fungi. We hypothesized that plant community changes and local plant
