Significance Previous estimations of carbon budgets in China’s terrestrial ecosystems varied greatly because the multiplicity data sources and inconsistency methodologies. By conducting a methodologically consistent field campaign across country, we estimated that total pool forests, shrublands, grasslands, croplands was 79.24 ± 2.42 Pg C. The density exhibited strong dependence on climate regime: it decreased with temperature but increased precipitation. country’s forests have large...
The long-term stressful utilization of forests and grasslands has led to ecosystem degradation C loss. Since the late 1970s China launched six key national ecological restoration projects protect its environment restore degraded ecosystems. Here, we conducted a large-scale field investigation literature survey biomass soil in China's forest, shrubland, grassland ecosystems across regions where were implemented (∼16% country's land area). We investigated changes stocks these evaluate...
Despite evidence from experimental grasslands that plant diversity increases biomass production and soil organic carbon (SOC) storage, it remains unclear whether this is true in natural ecosystems, especially under climatic variations human disturbances. Based on field observations 6,098 forest, shrubland, grassland sites across China predictions an integrative model combining multiple theories, we systematically examined the direct effects of climate, soils, impacts SOC storage versus...
Plant nitrogen (N) and phosphorus (P) content regulate productivity carbon (C) sequestration in terrestrial ecosystems. Estimates of the allocation N P plant tissues relationship between nutrient photosynthetic capacity are critical to predicting future ecosystem C under global change. In this study, by investigating concentrations leaves, stems, roots across China's biomes, we document large-scale patterns community-level C, N, P. We also examine possible correlation production as indicated...
The carbon budgets in terrestrial ecosystems China are strongly coupled with climate changes. Over the past decade, has experienced dramatic changes characterized by enhanced summer monsoon and decelerated warming. However, trends of net ecosystem production (NEP) under not well documented. Here, we used three models to simulate spatiotemporal variations China's NEP during 1982-2010 quantify contribution strengthened warming hiatus four distinct climatic regions country. Our results revealed...
Seasonal variation and provenance of organic matter in the surface sediments three gorges reservoir: Stable isotope analysis implications for agricultural management,
Abstract: One hundred and sixty plots, approximately every 100 m above sea level (a.s.1.) along an altitudinal gradient from 470 to 3 080 a.s.1. at the southern northern watershed of Mt. Shennongjia, China, were examined determine pattern plant species diversity. Shennongjia was found have high diversity, with 479 higher plants recorded. Partial correlation analysis detrended canonical correspondence (DCCA) based on diversity revealed that altitude main factor affecting spatial canopy...
Aim Studies comparing feeding habits across a genus in different geographical regions or habitats can identify factors associated with adaptive behaviour, linking key ecological traits between consumers and their environment. We investigated biogeographical patterns dietary composition trophic diversity the Martes relation to range environmental variables. hypothesized that widely distributed opportunistic species should demonstrate variations relative regional location (e.g. latitude,...
Rainfall is one of the primary sources chemical inputs in forest ecosystems, and basis nutrient cycling. Mixed evergreen deciduous broadleaved forests are currently most threatened ecosystems due to their sensitivity anthropogenic climate change. As such, understanding hydrochemical fluxes these systems critical for managing dynamics future. We investigate chemistry bulk precipitation, stemflow throughfall a mixed Shennongjia region Central China. Mean concentrations were higher than...
Abstract. Recent increases in atmospheric carbon dioxide (CO2) and temperature relieve their limitations on terrestrial ecosystem productivity, while nutrient availability constrains the increasing plant photosynthesis more intensively. Nitrogen (N) phosphorus (P) are critical for physiological activities consequently regulate productivity. Here, first time, we mapped N P densities concentrations of leaves, woody stems, roots, litter, soil forest, shrubland, grassland ecosystems across China...
Ongoing global climate change is predicted to increase the frequency and magnitude of extreme weather events, impacting population dynamics community structure. There is, however, a critical lack case studies considering how climatic perturbations affect biotic interactions. Here, we document an obligate seed dispersal mutualism was disrupted by temporally anomalous meteorologically interlude unseasonably frigid weather, with accompanying snowstorms, in subtropical China, during...
Abstract The scaling relationship between the concentrations of leaf nitrogen (N) and phosphorus (P), which can be formulated as [N] = α [P] β , shows relative investment plants in nutrient uptake. Most current knowledge on this topic is based studies at individual or species level. However, patterns these levels hardly reflect response vegetation ecosystems along environmental gradients. Here, we explored how demands a whole vary with productivity, climate soil availability by generalizing...
Extreme drought events have caused extensive and severe impacts on terrestrial ecosystem in last decades China. Given droughts may be more intense frequent under future climate change, accurate assessment of the impact vegetation primary production can provide reliably scientific supports for carbon sink potential. Numerous existing studies used Standardized Precipitation Evapotranspiration Index (SPEI) to discover drought-production relationships, however, most them just considered...
Leaf nitrogen (N) and phosphorus (P) resorption is a fundamental adaptation strategy for plant nutrient conservation. However, the relative roles that environmental factors functional traits play in regulating N P remain largely unclear, little known about underlying mechanism of affecting resorption. Here, we measured leaf 13 leaf, petiole, twig 101 representative broad-leaved tree species our target subtropical transitional forests. We integrated these multiple into economics spectrum...
The giant panda (Ailuropoda melanoleuca), is one of the world's most endangered species. Habitat loss and fragmentation have reduced its numbers, shrunk distribution, separated population into isolated subpopulations. Such isolated, small populations are in danger extinction due to random demographic factors inbreeding. We used least-cost modeling as a systematic approach incorporate satellite imagery data on ecological behavioral parameters collected during more than 10 years field research...
Abstract Understanding climatic influences on the proportion of evergreen versus deciduous broad‐leaved tree species in forests is crucial importance when predicting impact climate change forests. Here, we quantified geographical distribution subtropical China. The Relative Importance Value index ( RIV ) was used to examine regional patterns dominance and related three key variables: mean annual temperature MAT ), minimum coldest month (MinT), precipitation MAP ). We found decrease with...
Abstract It is critical to accurately estimate carbon (C) turnover time as it dominates the uncertainty in ecosystem C sinks and their response future climate change. In absence of direct observations losses, times are commonly estimated under steady state assumption ( SSA ), which has been applied across a large range temporal spatial scales including many at validity likely be violated. However, errors associated with improperly applying its covariance well sequestrations have yet fully...

It important to understand how factors affect changes in forest structure dynamics under environmental fluctuations. In this study, we explored initial size [diameter at breast height (DBH)], neighborhood competition, site condition on growth, based 3-year monitoring rate permanent plot (120 × 80 m) montane Fagus engleriana-Cyclobalanopsis multiervis mixed Mt.
