Arctic shrub expansion revealed by Landsat-derived multitemporal vegetation cover fractions in the Western Canadian Arctic [PDF]
, 2022 Warming induced shifts in tundra vegetation composition and structure, including circumpolar expansion of shrubs, modifies ecosystem structure and functioning with potentially global consequences due to feedback mechanisms between vegetation and climate.

Shrub expansion modulates belowground impacts of changing snow conditions in alpine grasslands
, 2022 Climate change is disproportionately impacting mountain ecosystems, leading to large reductions in winter snow cover, earlier spring snowmelt and widespread shrub expansion into alpine grasslands. Yet, the combined effects of shrub expansion and changing

Environmental Research Letters, 2021 Plant growth and distribution in high-latitude tundra ecosystems is strongly limited by nutrient availability and is critical for quantifying centennial-scale carbon-climate interactions. However, land model representations of plant–nutrient interactions

Shrub canopy induces a decline in lichen abundance and diversity in Nunavik (Québec, Canada)
Arctic, Antarctic, and Alpine Research, 2019 Lichens are an important component of biodiversity in northern ecosystems and are involved in diverse ecological processes. They contribute to nutrient availability through nitrogen fixation, are a substantial part of caribou winter diet, and influence ...

Shrub encroachment alters topsoil C:N:P stoichiometric ratios in a high-altitude forest cutover
iForest - Biogeosciences and Forestry, 2018 The effect of shrub encroachment on soil carbon (C): nitrogen (N): phosphorus (P) stoichiometric ratios are largely still unknown. We investigated this effect and the effect of shrub size in a high altitude forest cutover among four common shrub species:

A narrow window of summer temperatures associated with shrub growth in Arctic Alaska
Environmental Research Letters, 2020 Warming in recent decades has triggered shrub expansion in Arctic and alpine tundra, which is transforming these temperature-limited ecosystems and altering carbon and nutrient cycles, fire regimes, permafrost stability, land-surface climate-feedbacks ...

Integrative assessment of the effects of shrub coverage on soil respiration in a tundra ecosystem
, 2021 Shrub encroachment and soil respiration (SR) are predicted to increase in the tundra ecosystem under climate warming, but little is known regarding potential causal relationships between shrubs and SR at a local scale.

Frontiers in Ecology and Evolution, 2022 IntroductionThe alpine meadows are distributed widely and play a vital role in ecosystem service functions on the Qinghai-Tibet Plateau (QTP). Under the combined effect of climate change and overgrazing, shrubs display an apparent expansion trend ...
