2022-09-21Nitrogen budgets of a lower subtropical forest as affected by 6 years of over-canopy and understory nitrogen additionsAlthough tropical and subtropical regions have replaced temperate regions as the global-change hotspots for increased atmosphere nitrogen ( N ) deposition , whether the regional forests reach N saturation is still unclear .The research group of Vegetation and Landscape Ecology from South China Botanical Garden conducted a field experiment to qua... Although tropical and subtropical regions have replaced temperate regions as the global-change hotspots for increased atmosphere nitrogen (N) deposition, whether the regional forests reach N saturation is still unclear. Understory or floor N addition has been commonly used in N-deposition studies, but the results of such studies have recently be...Read More -
2022-09-09【CGTN】Rare and wonderful plants inside South China Botanical GardenShe also speaks to the experts inside the garden about their work in helping preserve biodiversity in China . 【CGTN】 25-Jul-2022The South China Botanical Garden in the city of Guangzhou was officially upgraded to a "national botanical garden" earlier this month. The organization was founded in 1929. It's the largest subtropical botanical garden in the world, with nearly 20,000 different species of plants. CGTN reporter Cao Chufeng shows...Read More

2022-09-06Long-term nitrogen deposition alters the dissolved organic matter composition in tropical forest soilsTo its mobility and biological instability .Based on a long-term simulative N deposition experiment in a primary tropical forest in south China , Prof . Xiankai Lu ’ group at South China Botanical Garden , explored the quantity , optical properties , and molecular-level.DOM composition in a way to benefit soil OC storage in the primary tropical... Dissolved organic matter (DOM) plays a key role in forest carbon biogeochemistry by linking soil organic carbon (SOC) sequestration and water fluxes, which is further shaped by elevated atmospheric nitrogen (N) deposition. Although enhanced SOC sequestration was evidenced in tropical forests due to rising N deposition, it remains unclear how lon...Read More -
2022-09-02Physiological traits and response strategies of four subtropical tree species exposed to droughtWorld-wide , forests are experiencing drought-induced mortality .Mortality patterns and alter community structure .In this study , saplings of four common tree species ( Ormosia pinnata , Dalbergia odorifera , Castanopsis fissa and Michelia macclurei ).Progressive drought stress .Representation of plot ( a ) and randomized biock design for plots... World-wide, forests are experiencing drought-induced mortality. However, physiological adaptation to drought is highly variable, which may lead to differential mortality patterns and alter community structure. In this study, saplings of four common tree species (Ormosia pinnata, Dalbergia odorifera, Castanopsis fissa and Michelia macclurei) grow...Read More

Climate warming has significantly altered the phenology of plants in recent decades. However, in contrast to the widely reported warming-induced extension of vegetative growing season, the response of fruit development period (FDP) from flowering to fruiting remains largely unexplored, particularly for woody plants.Read More

2022-08-29Ten years of warming significantly increased plant-derived carbon accumulation in an East Asian monsoon forestWarming affects the carbon cycle process of the terrestrial ecosystem by affecting the counterbalance between carbon input and output , and the stability of the carbon pool .Microbial transformation and mineral protection pathways of soil organic carbon stock and composition under long-term warming. Warming affects the carbon cycle process of the terrestrial ecosystem by affecting the counterbalance between carbon input and output, and the stability of the carbon pool. Although most studies showed that warming decreased soil organic carbon (SOC) content, there is still great uncertainty in the direction and extent of the warming effect on S...Read More -

Phosphorus (P) is one of the most important limiting nutrients in terrestrial ecosystems. The soils represent the largest P reserve (He et al., 2021a), which P storage determines the form and supply of soil P to plants, potential affecting the function of forest ecosystems. However, our understanding of the drivers of soil P pattern is stil...
