Published: Sept. 3, 2024

Shallow slope instability poses a significant ecological threat, often leading to severe environmental degradation. While vegetation, particularly woody plants, is commonly employed in stabilization, herbaceous vegetation offers distinct and underexplored advantages. This paper reviews the role of plants enhancing stability, analyzing their mechanical mechanisms. Through an extensive review literature, this challenges prevailing view that superior for finding can be equally or more effective under certain conditions. The key findings include identification specific root parameters species contribute soil reinforcement erosion control. highlights need further research on optimizing plant selection management practices maximize stabilization effects. These insights have practical implications engineering, offering guidance integrating into sustainable land strategies.

Response of Natural Forests and Grasslands in Xinjiang to Climate Change Based on Sun-Induced Chlorophyll Fluorescence

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(1), P. 152 - 152

Published: Jan. 4, 2025

In arid regions, climatic fluctuations significantly affect vegetation structure and function. Sun-induced chlorophyll fluorescence (SIF) can quantify certain physiological parameters of but has limitations in characterizing responses to climate change. This study analyzed the spatiotemporal differences response change across various ecological regions types from 2000 2020 Xinjiang. According China’s zoning, R1 (Altai Mountains-Western Junggar Mountains forest-steppe) R5 (Pamir-Kunlun Mountains-Altyn Tagh high-altitude desert grasslands) represent two extremes, while R2–R4 span forest-steppe ecosystems. We employed standardized precipitation evapotranspiration index (SPEI) at different timescales drought intensity frequency conjunction with global OCO-2 SIF products (GOSIF) normalized difference (NDVI) assess growth conditions. The results show that (1) between 2020, overall severity Xinjiang exhibited a slight deterioration, particularly northern (R1 R2), gradual transition short-term long-term R4 southern also displayed deterioration trend; however, remained relatively stable on SPEI24 timescale. (2) NDVI values an upward trend. However, densely vegetated areas (R1–R3), both declined, more pronounced decrease observed natural forests. (3) Vegetation showed stronger than Xinjiang, being sensitive structural (NDVI). R1, R2, R3 were primarily influenced by change, whereas affected Natural grasslands forests, lower cover are structurally impacted. provides important scientific basis for management adaptation emphasizing need differentiated strategies support sustainable development.

Lonely plants in arid land are functionally hyperdiverse

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 27, 2025

Abstract In Gross et al. 1 we produced the largest ever standardized dryland plant trait database including 133,769 measurements from 301 perennial species surveyed across 326 plots and six continents. Our findings indicate that arid hyper-arid drylands act as a global reservoir of phenotypic diversity, challenging common assumption harsh environmental conditions reduce diversity. Tordoni 2 speculate larger diversity in environments found our study is overestimated misinterpreted. The re-analyses presented here further confirm patterns originally reported are robust, thus concerns not well-founded do apply to study. We stand for main conclusions maintain lonely plants land functionally hyperdiverse.

Soil organic carbon thresholds control fertilizer effects on carbon accrual in croplands worldwide

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: March 27, 2025

Abstract Initiatives to restore soil fertility and mitigate global warming rely on rebuilding organic carbon (SOC). Nitrogen (N) fertilization is crucial for crop yields but affects SOC unpredictably due varying responses of particulate (POC) mineral-associated (MAOC) pools initial levels. To clarify these effects, here, by combining a meta-analysis with continental-scale field experiments, we determine that an threshold 15 g C kg −1 controls the effect N POC MAOC. In SOC-poor soils (< ), fertilizer increases plant-derived inputs promotes aggregation, favouring accumulation. Conversely, in SOC-rich soils, stimulates microbial metabolic efficiency, leading larger necromass production stabilization mineral protection, observed as more pronounced MAOC accrual. Our findings reveal how thresholds shape response active stable fertilization, consequences accrual cropland globally.

Plant Acquisitive Strategies Promote Resistance and Temporal Stability of Semiarid Grasslands

Ecology Letters, Journal Year: 2025, Volume and Issue: 28(4)

Published: April 1, 2025

Among ecologists, it is widely believed that conservative growth strategies of plants are crucial for sustaining ecosystem stability, while the potential stabilising role acquisitive has received little attention. We investigated relationships between plant traits and three stability dimensions-temporal resistance resilience-using two complementary datasets from drought-affected semi-arid grasslands: a temporal community survey single site 1000-km transect with satellite-derived productivity estimates. found strikingly consistent patterns datasets, grasslands dominated by exhibiting greater productivity. Acquisitive enhance facilitating drought escape avoidance, rather than tolerance typically associated strategies. These results highlight important but underappreciated in enhancing to disturbances maintaining grasslands.

Ecological thresholds and transformations due to climate change: The role of abiotic stress

Ecosphere, Journal Year: 2025, Volume and Issue: 16(4)

Published: April 1, 2025

Abstract An ecological threshold is the point at which a comparatively small environmental change triggers an abrupt and disproportionately large response. In face of accelerating climate change, there concern that ecosystem transformations will become more widespread as critical thresholds are crossed. There has been ongoing debate, however, regarding prevalence across natural world. While ubiquitous in some ecosystems, have difficult to detect others. Some studies even concluded responses uncommon world overly emphasized literature. As ecologists who work ecosystems chronically exposed high abiotic stress, we consider be concepts can greatly advance understanding inform management. But quantifying challenging, if not impossible, without data strategically collected for purpose. Here, present conceptual framework built upon linkages between climate‐driven responses, risk transformation. We also simple approach stress gradients. hypothesize especially influential where autotroph diversity low foundation species play prominent role. Abiotic conditions these environments often near physiological tolerance limits species, means changes trigger landscape‐level transformations. Conversely, alleviation allow thrive spread into previously inhospitable locations. provide examples this behavior from four high‐stress environments: coastal wetlands, coral reefs, drylands, alpine ecosystems. Our overarching aim review clarify strong relationships thresholds, transformation under change.
