2023-04-20Divergent accumulation of amino sugars and lignins mediated by soil functional carbon pools under tropical forest conversionPlant - ( e . g . lignin ) and microbial-derived ( e . g . microbial necromass ) metabolic products are important sources of soil organic carbon ( SOC ) pool .Co-corresponding authors were Pro . Zhanfeng Liu in South China Botanical Garden and Prof . Naishen Liang in National Institute for Environmental Studies ( Japan ) . https : / / doi . org ... Plant- (e.g. lignin) and microbial-derived (e.g. microbial necromass) metabolic products are important sources of soil organic carbon (SOC) pool. Owing to the relative higher persistence of microbial-derived C, the composition of sources play a vital role in the stabilization of SOC pool. Meanwhile, labile particulate organic carbon (POC) and re...Read More -
2023-02-23Response mechanism of forest soil water flow at Dinghushan areaWater flow directly affects solute flow , groundwater exchange and plant water uptake .Capacity are better in the first two forest types than in Pine forest , however , soil water flow patterns and preferential flow levels do not show the same.Of water flow and the degree of preferential flow .Preferential flow ( PF-fr , LI , PI ) showed varying...Read More
Soil water flow behavior generally includes two forms, preferential flow and matrix flow. The active degree of water flow directly affects solute flow, groundwater exchange and plant water uptake. In this study, we analyzed the soil water flow patterns and driving mechanisms in three different forest types (BF, MF and PF) in the subtropical... -
2023-02-09Estimating Aboveground Carbon Dynamic of China Using Optical and Microwave Remote Sensing Datasets from 2013 to 2019Optical depth ( VOD ) ) and three optical ( normalized difference vegetation index , leaf area index , and tree cover ) remote sensing vegetation products , this study., followed by L-VOD ( R ？ = ？ 0.83 ) , which outperform the other VODs . An AGC estimation model was proposed to.Guizhou ( + 22.35 Tg C yr-1 ) , Sichuan ( + 14.49 Tg C yr-1 ) , ... Over the past two to three decades, Chinese forests are estimated to act as a significant carbon sink, yet the magnitude and spatial patterns of this sink differ considerably among studies. Using three microwave (L- and X-band vegetation optical depth (VOD)) and three optical (normalized difference vegetation index, leaf area index, and tree cov...Read More -
2023-02-09Genomic vulnerability to climate change in Quercus acutissima, a dominant tree species in East Asian deciduous forestsTo future climate change is critical for biodiversity conservation , optimal afforestation , and sustainable development of forest resources .Species in East Asian deciduous forests ” was published in Molecular ecology .Geographic distribution , population structure , and genomic variation patterns of Quercus acutissima .Local , forward , and r... Rapid global climate change is one of the serious threats to biodiversity. Forest tree species play important roles in maintaining the stability of ecosystem and improving ecosystem services. Understanding how the evolutionary process shape the landscape of genetic variation and contribute to the response of forest species to future climate chan...Read More -
2022-12-20Temperature dependence of ecosystem carbon, nitrogen and phosphorus residence times differs between subtropical and temperate forests in ChinaInputs and outputs of carbon ( C ) , nitrogen ( N ) and phosphorus ( P ) are the needs to maintain functioning and.Development of ecosystem , and are also functions of ecosystem .Therefore , residence times of C and nutrients are important evidences to evaluate.Influence of climate , vegetation , soil and topography on ecosystem residence times ... Inputs and outputs of carbon (C), nitrogen (N) and phosphorus (P) are the needs to maintain functioning and development of ecosystem, and are also functions of ecosystem. Therefore, residence times of C and nutrients are important evidences to evaluate stability of ecosystem structure and function. The residence times are influenced by internal ...Read More -

Soil is the largest carbon (C) reservoir of terrestrial ecosystems, and at least half of soil organic carbon is stored in forests. Tropical and subtropical forests play a vital role in the global forest carbon cycle, accounting for 78% of total global forest carbon emissions and 55% of total carbon uptake. Human activities also lead to incr... -

Aspergillus flavus is a common fungus that can infect agricultural products, medicinal herbs and processed foods. It can produce aflatoxins during infection. Uncontrolled exposure to aflatoxin may cause 28.2% of all liver cancer cases globally. A．flavus has caused significant losses to agricultural... -
2022-12-13Temporal patterns of soil carbon emission in tropical forests under long-term nitrogen depositionAffects soil respiration with time in tropical and subtropical forests . Human activities have resulted in serious atmospheric nitrogen deposition in large-scale areas of the world. The reactive nitrogen deposited into forest ecosystems provides nutrient available to plants and microbes, which further affects their growth, biomass accumulation, and carbon emission via respiration. Although nitrogen deposition can reg...Read More
