2023-04-24SCBG researchers reveal the stomatal responses of terrestrial plants to global changeImpact of various global change factors on stomatal conductance in land plants .Global change factors were generally additive , but as effect sizes increased , they tended to be antagonistic ( meaning the combined effects of two factors.For more information , please visit https : / / doi . org / 10.1038 / s41467-023 - 37934-7 . Stomatal conductance is an important eco-physiological trait of plants and a fundamental parameter of earth system models. Previous studies have shown that stomatal conductance is sensitive to environmental change, but little is known about how it is affected by multiple global change factors.Read More

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 -
