Populus euphratica, a key tree species in the ecologically fragile area of Tarim River Basin, plays crucial role maintaining ecological balance desert. In order to explore response euphratica leaves river water resources and drought climate change, complex topological relationship between leaf traits was comprehensively analyzed by establishing trait network mainstream River, central that play regulating phenotype were identified.

Forest carbon stocks increase with higher dominance of ectomycorrhizal trees in high latitude forests

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: July 16, 2024

Understanding the mechanisms controlling forest carbon accumulation is crucial for predicting and mitigating future climate change. Yet, it remains unclear whether dominance of ectomycorrhizal (EcM) trees influences entire forests. In this study, we analyzed inventory data from over 4000 plots across Northeast China. We find that EcM tree consistently exerts a positive effect on tree, soil, stocks. Moreover, observe these effects are more pronounced during unfavorable conditions, at lower species richness, early successional stages. This underscores potential increasing native not only to enhance stocks but also bolster resilience against change in high-latitude Here show managers can make informed decisions optimize by considering various factors such as mycorrhizal types, climate, stages, richness.

Fuel architecture influences interspecific variation in shoot flammability, but not as much as leaf traits

Journal of Ecology, Journal Year: 2024, Volume and Issue: unknown

Abstract Plant flammability is strongly influenced by functional traits, meaning that the quantitative measurement of trait–flammability relationships key to understanding why some species burn better than others. While between and leaf traits are well‐studied, role architectural has rarely been assessed. Shoots preserve architecture plants; therefore, shoot‐level offer great promise for determining relative influence fuel on flammability. We quantified plant burning 70‐cm‐long shoot samples from 65 indigenous exotic New Zealand trees shrubs measured a range same individuals.

Intercomparison of global foliar trait maps reveals fundamental differences and limitations of upscaling approaches

EarthArXiv (California Digital Library), Journal Year: 2023, Volume and Issue: unknown

Published: April 14, 2023

Foliar traits such as specific leaf area (SLA), nitrogen (N) and phosphorus (P) concentrations play an important role in plant economic strategies ecosystem functioning. Various global maps of these foliar have been generated using statistical upscaling approaches based on in-situ trait observations.Here, we intercompare upscaled at 0.5° spatial resolution (six for SLA, five N, three P), categorize the used to generate them, evaluate with estimates from a database vegetation plots (sPlotOpen). We disentangled contributions different functional types (PFTs) characterized differences between two metrics: community weighted mean (CWM) top-of-canopy (TWM).We found that SLA N differ drastically fall into groups are almost uncorrelated (for P only one group were available). The primary factor explaining is exclusive use PFT information combined remote sensing-derived land cover products while other mostly relied environmental predictors. impact TWM or CWM patterns was considerably smaller than including information. exhibit considerable similarities strongly driven by cover. not PFTs show lower level similarity tend be individual variables.Overall, better reproduce between-PFT distributions plot-level sPlotOpen data, performed similarly capturing within-PFT variation. Upscaled both moderately correlated grid-cell-level data (R = 0.2-0.6), overall higher correlations N.Our findings highlight importance explicitly accounting within-grid-cell variation, which has implications applications existing future efforts.

The Role of Plant Evolutionary History in Shaping the Variation in Specific Leaf Area Across China

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(4)

Published: April 1, 2025

ABSTRACT Specific leaf area (SLA, per unit dry mass) occupies a central position in both community assembly and ecosystem functioning. Although SLA has significant phylogenetic signals, how to what extent the evolutionary history influences variation remain poorly understood. In this study, based on dataset containing 1264 plant species belonging 549 genera 141 families gymnosperms, monocots, eudicots across China, we analyzed of climatic conditions soil properties SLA, calculated signals quantified relative contributions (represented by interspecific relatedness intraspecific variation) SLA. The results showed that accounts for 50.46% total variance followed (36.12%), (30.68%), (24.74%). Along tree, split between angiosperms gymnosperms had largest contribution Other detailed splits (e.g., monocots eudicots, within Rosidae, etc.) but much smaller contributions. relationship environmental variables (climatic properties) was different with having larger than properties, implying interactive effects environment Within woody angiosperms, deciduous evergreen exhibited differential responses factors, suggesting non‐negligible role longevity explaining Our highlighted more important previous studies. Neglecting such great could lead biased conclusions if rate does not keep pace rapidly changing environments future.
