Changes in the understory plant community and ecosystem properties along a shrub density gradient
Arctic Science, 2018 Climate warming is projected to alter the vegetation community composition of arctic and alpine ecosystems including an increase in the relative abundance and cover of deciduous shrubs.

Widespread shrubification on European mountain summits
Abstract Shrubs are expanding across the cold ecosystems of our planet with potentially profound consequences for their biodiversity and functioning. However, evidence is still strongly biased towards the Arctic tundra, while a large-scale assessment of shrub expansion in alpine areas above the elevational treeline is missing so far.

Reindeer use of low Arctic tundra correlates with landscape structure
Environmental Research Letters, 2020 Rapid climate change in Arctic regions is linked to the expansion of woody taxa ( shrubification ), and an increase in biomass as tundra becomes greener.

Ecohydrology, Volume 18, Issue 8, December 2025.ABSTRACT Beaver dams substantially reshape peatland hydrology, yet their influence on plant phenology, a key driver of ecosystem carbon dynamics, remains poorly understood. We used UAV‐based RGB imagery to quantify seasonal changes in greenness (GCC) of sedge (Carex spp.) across three hydrological treatments in a Canadian Rocky Mountain peatland ...

Lidar-derived estimates of boreal shrub biomass in Southcentral Alaska
Environmental Research LettersDespite widespread observations of shrub proliferation and expansion (shrubification), few studies quantify shrub biomass at the regional scale. Here we describe and implement a two-part modeling approach to estimate and map tall shrub (diameter at root ...

Hydrological Feedbacks in Northern Peatlands 2: Peat Depth as a Control on Peatland Resilience
Ecohydrology, Volume 18, Issue 8, December 2025.ABSTRACT As climate change increasingly threatens the northern peatland net carbon sequestration function, there is a pressing need to better understand the limits of ecohydrological regulatory mechanisms. This is especially urgent for shallow peatlands (< 40‐cm average peat depth), which consistently experience water stress with greater intensity ...

Bird communities of the arctic shrub tundra of Yamal: habitat specialists and generalists.
PLoS ONE, 2012 BackgroundThe ratio of habitat generalists to specialists in birds has been suggested as a good indicator of ecosystem changes due to e.g. climate change and other anthropogenic perturbations.

Hydrological Processes, Volume 39, Issue 12, December 2025.Daily mean seasonal origin index (SOI) of xylem sampled at Forest (blue circles), Buckbrush (green triangles) and Sparse Shrub (orange squares) in 2019 (left) and 2020 (right). Values above/below 0 indicate xylem water was more reflective of summer/winter precipitation respectively.

Composition of organic acids secreted by alpine shrub roots and its influencing factors
Biologia PlantarumBackground and aims: There appears to be a strong correlation between the rapid proliferation of shrubs in the alpine grassland of the Qinghai-Tibet Plateau and the root exudates of these plants.
