Elevation‐Dependent Vegetation Greening and Its Responses to Climate Changes in the South Slope of the Himalayas

Geophysical Research Letters, Journal Year: 2025, Volume and Issue: 52(4)

Published: Feb. 13, 2025

Abstract The South Slope of the Himalayas (SSH) is witnessing dynamic shifts in vegetation greenness driven by climatic conditions across elevation variability. Here, we analyzed greening patterns natural vegetated surfaces along elevational gradient and examined their connection to climate changes from 2000 2022. Over 50% area SSH exhibited significant greening, with higher rates Central (CH) Western (WH) compared Eastern (EH). relative change rate (RCR) showed a notable increasing ∼2,600 ∼5,000 m, followed decreasing trend all subregions. Results that air temperature promoted significantly high mountains but caused heat stress lowlands CH WH. Precipitation supported growth middle region except EH, which faced waterlogging stress. These findings are valuable for understanding under future advancing our knowledge ecosystem responses.

Unveiling the role and crosstalk of hydrogen sulfide with other signalling molecules enhances plant tolerance to water scarcity

Physiologia Plantarum, Journal Year: 2025, Volume and Issue: 177(2)

Published: March 1, 2025

Abstract Drought, a major factor limiting global crop yields, disrupts plant growth, water interactions, and overall use efficiency. Hydrogen sulfide (H 2 S), key gasotransmitter, has become crucial signalling molecule in biology. It promotes growth development while significantly contributing to the plant's response various abiotic stresses, including drought. This review explores how H₂S mitigates drought stress plants crosstalks with molecules such as nitric oxide, melatonin, abscisic acid, γ‐aminobutyric polyamines, others. highlights these acting either upstream or downstream, enhance resistance. Furthermore, involves persulfidation, which modifies protein thiol groups protect against oxidative damage. The underscores role of persulfidation reducing reactive oxygen species accumulation maintaining redox homeostasis under stress. aims elucidate relief expand our knowledge it contributes resistance during scarcity by examining its regulatory mechanisms interactions. Additionally, proposes practical strategies for enhancing agricultural practices face growing conditions, offering methods leverage improving tolerance scarcity.

Quantifying the impact of precipitation fluctuations on forest growth in Northeast China

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: May 20, 2025

In the context of climate change, escalating frequency global precipitation fluctuations amplifies uncertainties in assessing impact on forest ecosystem productivity. Hence, elucidating dynamic relationship between characteristics and growth can provide effective management strategies for addressing change. This study utilizes data from 1982 to 2022 construct amplitude analyzes response northern China these variations. The 13.7% region's is declining, with 8.1% area showing significant degradation. core degradation zones are located semi-arid regions frequencies ≥ 12 amplitudes ≤ 60 mm subhumid 14 65 mm. zone, deciduous broadleaf shrublands have greatest degraded (2.8×104 ha), but needleleaf forests highest proportion (57.1%), while (1.7×105 ha) (9.3%). not only provides a novel perspective evaluating responses characteristics, also offers crucial theoretical support advancing implementation Nature-based Solutions practical applications.
