Mountain forests in biodiversity hotspots show complex responses to climate and topographic gradients. However, the effect of synergistic controls elevation on Net Primary Productivity (NPP) dynamics remain insufficiently quantified mountains. Southwest China’s mountains are Asia’s most biodiverse temperate region with pronounced vertical ecosystem stratification, representing a critical continental carbon sink. This study investigated spatiotemporal driving mechanisms NPP typical mountain ecosystems over past three decades using high-resolution modeling framework integrated relative importance analysis, Geodetector, an elevation-dependent model. The results showed that (1) revealed significant increasing trend, rising from 634 ± 325 748 348 g C m−2 yr−1 (mean rate 4 yr−1) 1990 2018. Spatially, rapid increases occurred eastern regions. (2) Rising CO2 warming (dominate 17% regions) drove interannual growth, thresholds dictating driver dominance. governed low elevation, while temperature controlled higher (>4800 m). (3) model more nonlinear relationship between identifying distinct phases: saturation phase (<500 m) negligible decay NPP; transition (500–3500 linear decline (NPP loss 29 m⁻2 yr⁻1 per 100 m); collapse (>3500 continuously attenuated losses average 10.5 reflecting high-elevation vegetation adaptation extreme conditions. (4) Land cover dominated spatial heterogeneity was amplified by interactions temperature, highlighting vegetation–climate–topography coupling mechanism critically shapes productivity patterns.

Forest biomass, as a carrier of carbon, is an important indicator for judging forest productivity, stability and sustainable development capacity. Using the survey data sample plots in eight areas central Hainan, biomass distribution tropical mountain rainforests National Park Hainan Tropical Rainforest different community sizes, diameter classes, altitudes spaces was measured to explore relationship between environmental factors. The results show that (1) total area montane about 983.70 km2, distributed within altitude range 700–1300 m; aboveground 25.208 million tons, which decreased first then increased with increasing altitude, average per unit 236.00 t·hm−2; (2) primary accounted 83.23% rainforest only 29.84% area, generally higher than secondary forest; (3) medium- large-diameter trees were main carriers rain forests. More 83.73% concentrated trees. this study provide reference others aiming perform measurement evaluation carbon sink capacity neutrality ecosystems or maintain regional biodiversity.

This study aimed explore characteristics AGB variations gradients for and tree species components Qinling–Daba Mountains. Based on 329 field survey plots, including four sampling transects representative mountains, individual was calculated using allometric biomass equations. Further, generalized additive models (GAMs) were used investigate relationships between (broadleaf forests, coniferous mixed coniferousbroadleaf shrublands) three (total (tAGB), broadleaf (bAGB), (cAGB)) across eight regions. results showed that is significantly related (p < 0.05), with showing a unimodal pattern elevation, increasing shrubland exhibiting noticeable rise at higher elevations. regions also significant displaying monotonically trend small range or bimodal large range, while generally increased elevation. Although influenced AGB, variation R2 values indicated not sole determinant variation. improves understanding spatial

Climate change, including drought, threatens ecosystems across the globe. The current study investigated effects of species diversity and biochar application on performance productivity five native Omani under control drought conditions. A fully controlled greenhouse experiment was conducted in which three different diversities (one, two, four species) were grown treatments: biochar+drought, biochar, control. Productivity measured through total biomass root-to-shoot ratio), while assessed form plant functional traits (plant height, specific leaf area (SLA), root length (SRL). Nutrient availability soil using organic carbon (SOC) nitrogen (STN). Soil microbial content determined "Cmic" basal respiration. Biodiversity analyzed complementarity effect (CE), selection (SE), net biodiversity (NBE). indicated that high resulted in: 1. with 66.6% greater a 3% reduction RSR, 2. enhanced performance, plants growing 25% taller, 50% higher SLA, SRL, 3. more fertile soil, SOC STN increasing by 40% 33.3%, respectively, 4. improved content, Cmic rising 15% respiration one-third conditions compared to monoculture. These results highlight intricate interactions between climate change biodiversity, are crucial for predicting impact changes composition ecosystem processes and, subsequently, restoring arid Oman.

Summary Global forest restoration initiatives provide an important chance to recover biodiversity and enhance functions services. Over recent decades, functional diversity (FD) has been regarded as a key driver of the positive relationships between ecosystem functioning (BEF). Despite extensive observations on associations tree FD various functions, we still lack sufficient mechanistic understanding consequences in forests scientific guidance for global efforts. Hereafter, revisit seek clarify pathways through which influences productivity, example, species complementarity dominance effects. We discuss how affects via changes other trophic levels, providing more or diverse food, habitat, litter. Future work BEF should examine dependence effects environmental context predict under change scenarios. Ultimately, propose several strategies incorporating into designs reinstate current future conditions.
