Declining temperature and increasing moisture sensitivity of shrub growth in the Low‐Arctic erect dwarf‐shrub tundra of western Greenland

Ecology and Evolution, 2022
Evergreen dwarf shrubs respond swiftly to warming in the cool and dry High Arctic, but their response in the warmer Low Arctic, where they are expected to be outcompeted by taller species under future warming, remains to be clarified. Here, 12,528 annual

Does shrub encroachment reduce foraging grass abundance through plant-plant competition in Lesotho mountain rangelands? [PDF]

PeerJ, 2022
Shrub encroachment is understood to be an important problem facing rangeland ecosystems globally. The phenomenon is still poorly understood both in regard to its impacts (e.g., on diversity, productivity, and soil properties) and its causes. We study the

Effects of shrub encroachment on grassland community and soil nutrients among three typical shrubby grasslands in the alpine subhumid region of the Qinghai-Tibet Plateau, China

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 ...

Non-growing season plant nutrient uptake controls Arctic tundra vegetation composition under future climate

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

Computing Shrub-Depth Decompositions [PDF]

, 2020
Shrub-depth is a width measure of graphs which, roughly speaking, corresponds to the smallest depth of a tree into which a graph can be encoded. It can be thought of as a low-depth variant of clique-width (or rank-width), similarly as treedepth is a low ...

Effects of shrub expansion on methane emissions from temperate wetlands and their regulatory mechanisms

Geoderma
Climate warming and human activities have led to widespread expansion of shrubs in many wetlands, altering the distribution patterns of native vegetation and disrupting C cycling.

Field Simulation of Global Change: Transplanting Northern Bog Mesocosms Southward [PDF]

, 2010
A large proportion of northern peatlands consists of Sphagnum-dominated ombrotrophic bogs. In these bogs, peat mosses (Sphagnum) and vascular plants occur in an apparent stable equilibrium, thereby sustaining the carbon sink function of the bog ecosystem.

Strong shrub expansion in tundra-taiga, tree infilling in taiga and stable tundra in central Chukotka (north-eastern Siberia) between 2000 and 2017

Environmental Research Letters, 2020
Vegetation is responding to climate change, which is especially prominent in the Arctic. Vegetation change is manifest in different ways and varies regionally, depending on the characteristics of the investigated area.

Warming-induced phenological mismatch between trees and shrubs explains high-elevation forest expansion

National Science Review, 2023
 Despite the importance of species interaction in modulating the range shifts of plants, little is known about the responses of coexisting life forms to a warmer climate. Here, we combine long-term monitoring of cambial phenology in sympatric trees and shrubs at two treelines of the Tibetan Plateau, with a meta-analysis of ring-width series ...
