ARCTICThe expansion of deciduous shrubs is among the most conspicuous and widespread of the phenomena affecting tundra regions under a warming climate. While this process is expected to affect the distributions of terrestrial vertebrates, empirical assessments

Effects of arctic shrub expansion on biophysical vs. biogeochemical drivers of litter decomposition [PDF]
Ecology, 2014 Climate warming in arctic tundra may shift dominant vegetation from graminoids to deciduous shrubs, whose functional traits could, in turn, alter biotic and abiotic controls over biogeochemical cycling of carbon (C) and nitrogen (N).

Tundra shrub expansion may amplify permafrost thaw by advancing snowmelt timing
Arctic Science, 2019 The overall spatial and temporal influence of shrub expansion on permafrost is largely unknown due to uncertainty in estimating the magnitude of many counteracting processes.

Shrub Expansion is Mainly Affected by Climate-Dominated Functional Traits in Alpine Meadow
Frontiers in Environmental Science, 2022 Shrub expansion has been reported mostly in dry and semi-arid ecosystems worldwide. Shrub expansion is also a serious ecological issue in alpine and cold regions.

Seasonal facilitative and competitive trade‐offs between shrub seedlings and coastal grasses [PDF]
Ecosphere, 2020 Shrub expansion is occurring in grasslands globally and may be impacted by the balance of competition and facilitation with existing grasses. Along the mid‐Atlantic and Gulf coasts, the native shrub Morella cerifera (wax myrtle) is rapidly expanding and ...

Lacon-, Shrub- and Parity-Decompositions: Characterizing Transductions of Bounded Expansion Classes [PDF]
Logical Methods in Computer Science, 2023 The concept of bounded expansion provides a robust way to capture sparse graph classes with interesting algorithmic properties. Most notably, every problem definable in first-order logic can be solved in linear time on bounded expansion graph classes.

Arctic riparian shrub expansion indicates a shift from streams gaining water to those that lose flow [PDF]
Communications Earth & Environment, 2020 Shrub expansion has been observed across the Arctic in recent decades along with warming air temperatures, but tundra shrub expansion has been most pronounced in protected landscape positions such as floodplains, streambanks, water tracks, and gullies ...

Implications of evergreen shrub expansion in the Arctic [PDF]
Journal of Ecology, 2018 Arctic shrub expansion is occurring across large parts of the tundra biome and its potential ecological repercussions have been widely discussed. But while the term “shrub expansion” often implicitly refers to an increase in tall, deciduous species such ...
