Shrub expansion raises both aboveground and underground multifunctionality on a subtropical plateau grassland: coupling multitrophic community assembly to multifunctionality and functional trade-off [PDF]

Frontiers in Microbiology, 2023
IntroductionShrubs have expanded into grasslands globally. However, the relative importance of aboveground and underground diversity and the relative importance of underground community assembly and diversity in shaping multifunctionality and functional ...

Dispersal and fire limit Arctic shrub expansion [PDF]

Nature Communications, 2022
Shrub encroachment trends are widespread yet complex. Here the authors demonstrate that not considering dispersal and fire leads to overestimating shrub expansion in Arctic tundra and therefore its role as carbon sink.

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.

Shrub Expansion Impacts on Carbon, Nitrogen, and Sulfur Cycles and Microorganism Communities in Wetlands in Northeastern China [PDF]

Microorganisms
Marsh wetland degradation and shrub expansion, driven by human activities and climate change, can impact carbon, nitrogen, and sulfur cycles by soil microorganisms.

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.

Litter accumulation suppresses grass production but facilitates shrub expansion in a long‐term fenced grassland

Ecosphere
Shrub expansion is increasing in grasslands worldwide and has profound effects on biodiversity and ecosystem functions. Shrub expansion has primarily been explained by extrinsic factors such as climate change and human activities, yet the roles of ...

The soil organic carbon and its labile fractions are highest during moderate shrub expansion stage in the alpine meadow shrub expansion process

Global Ecology and Conservation
Shrub expansion has a profound influence on regional carbon cycling. However, understanding the dynamics of soil carbon fractions and their driving factors along shrub expansion gradients remains critical for accurately assessing the ecosystem's carbon ...

Changing sub-Arctic tundra vegetation upon permafrost degradation: impact on foliar mineral element cycling [PDF]

Biogeosciences, 2022
Arctic warming and permafrost degradation are modifying northern ecosystems through changes in microtopography, soil water dynamics, nutrient availability, and vegetation succession.

Nitrogen fixing shrubs advance the pace of tall-shrub expansion in low-Arctic tundra

Communications Earth & Environment, 2023
Tall deciduous shrubs are critically important to carbon and nutrient cycling in high-latitude ecosystems. As Arctic regions warm, shrubs expand heterogeneously across their ranges, including within unburned terrain experiencing isometric gradients of ...
