2023-06-07Negative responses of terrestrial nitrogen fixation to nitrogen addition weaken across increased soil organic carbon levelsRates while obligate N fixers are excluded as soil N becomes rich .However , this view contradicts the observation that N fixation does not decline in many.Of the Total Environment , with the linked paper below : https : / / www . sciencedirect . com/science/article/pii/S0048969.The traditional view versus a novel model regarding the relationshi...Read More
It is generally thought that biological nitrogen (N) fixation is energetically expensive and facultative N fixers reduce N fixation rates while obligate N fixers are excluded as soil N becomes rich. However, this view contradicts the observation that N fixation does not decline in many terrestrial ecosystems under N enrichment. Based on met... -
2023-06-05Long-term nitrogen addition does not increase phosphorus demand of plants in a nitrogen-saturated tropical forestIn recent decades , nitrogen deposition has exerted a substantial impact on biogeochemical cycles.Subtropical evergreen broad-leafed forest in Dinghushan Nature Reserve , Guangdong , we explored the impacts of 18 - year nitrogen additions on leaf phosphorus.Cycling and vegetation productivity in nitrogen-rich forest ecosystems , particularly con... In recent decades, nitrogen deposition has exerted a substantial impact on biogeochemical cycles of terrestrial ecosystems across the globe. While phosphorus is a vital macronutrient necessary for all organisms, it assumes a crucial role in physiological processes associated with protein and genetic material synthesis, energy transfer, membrane ...Read More -

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...
