Temporal and habitat-specific variations in drivers of aboveground biomass dynamics in a Chinese subtropical forest

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 21, 2025

Understanding the mechanisms governing biodiversity-biomass relationships across temporal and spatial scales is essential for elucidating how abiotic biotic factors influence ecosystem function in natural forests. However, simultaneous contributions of multiple (e.g., topography) structural diversity) to aboveground biomass dynamics (ΔAGB) over time habitat types remain inadequately understood. To address this gap, we evaluated changes a decade various habitats, disentangling relative influences topography multidimensional diversity on ΔAGB through datasets from forest inventories conducted between 2007 2017, along with phylogenetic relatedness, functional traits, environmental variables subtropical China. Our findings indicate that at community level experienced significant decline followed by an increase decade, predominantly driven low-valley habitat. In contrast, no statistically alterations were detected mid-hillside high-ridge habitats. Furthermore, determinants exhibited variation. During 2007-2012 period, was primarily influenced diversity, accounting 66.11% 21.35% importance, respectively. subsequent 2012-2017 emerged as key factors, explaining 48.46% 36.43% Additionally, observed drivers effects impacting variability different types. summary, our study underscores spatiotemporal dependence within ecosystems, thereby enhancing understanding complex biodiversity-ecosystem functioning relationships.

Altitudinal Variation in Species Diversity, Distribution, and Regeneration Status of a Secondary Picea Forest in Guandi Mountain, Northern China

Forests, Journal Year: 2024, Volume and Issue: 15(5), P. 771 - 771

Published: April 27, 2024

Altitude plays a crucial role in shaping the diversity and distribution of species forest landscapes mountainous regions. However, existing studies often lack comprehensive analysis intricate relationships among environmental factors, disturbances, diversity. This study aims to address this gap by thoroughly analyzing major species’ diversity, distribution, regeneration status, along with their influencing across different altitudinal gradients (1850 2350 m). Field surveys were conducted examine vegetation layers secondary Picea Guandi Mountain. The key findings from include following: (1) area recorded total nine adult trees, belonging eight genera five families, fourteen shrubs fifty-two herb representing forty-eight twenty-six families. Dominant varied layers, asperata Mast. Larix principis-rupprechtii Mayr. dominating arborous layer, Lonicera ferdinandii Franch. Cotoneaster acutifolius Turcz. shrub Poa pratensis L.

Effects of grazing on functional diversity along secondary succession in a tropical dry forest (Caatinga, Brazil)

Applied Vegetation Science, Journal Year: 2024, Volume and Issue: 27(2)

Abstract Aim Livestock production is among the main anthropogenic disturbances in seasonally dry tropical forests. However, its effects on plant functional composition forests poorly understood. Our goal was to analyze variation both and diversity of communities under goat grazing at different ages fallow a forest. Location Brazilian forest ( Caatinga ) Rio Grande do Norte State, northeastern Brazil. Methods We measured height, leaf area, specific area all shrub‐tree herbaceous species along gradient stocking rate, years grazing, age fallow. Additionally, we quantified foliar contents nitrogen, phosphorus, tannins tree shrub layer. tested deforestation using linear mixed models. Results findings suggest that not altered when secondary succession are examined independently. interaction factors has affected diversity, particularly Although influenced traits layer, overall remained unaltered by succession, or their interaction. Conclusions Grazing does interfere with natural process nor diminish . Therefore, appropriate management, can coexist conservation goals
