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 -
2022-12-20A series of research progresses achieved by Xiaoliang Station on how nitrogen deposition affects soil carbon pools in tropical forests and its mechanismsCarbon pool and its components .Conceptual diagram showing the effect of accumulation of GRSP and MRC on SOC content and potential microbial mechanisms under nitrogen deposition conditions .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 -
2022-12-06Distinct patterns of soil bacterial and fungal community assemblages in subtropical forest ecosystems under warmingTropical monsoon climate .Composition were asynchronous , likely due to contrasting community assembly processes .Highlighted that multiple factors regulate microbial community composition , with temperature being a principal driver in both dry and wet seasons ( Fig.Effects of warming over a 6 - year period on microbial community structure .Thus... Climate change globally affects soil microbial community assembly across ecosystems. However, little is known about the impact of warming on the structure of soil microbial communities or underlying mechanisms that shape microbial community composition in subtropical forest ecosystems. To address this gap, we utilized natural variation in temper...Read More -
2022-11-18"Difficult Sweet Potato Road" - South China Botanical Garden of Chinese Academy of Sciences made an important breakthrough in the research on the genetic basis of sweet potato insect resistanceSweet potatoes , accounting for more than 60% of the world ' s total production . Sweet potatoes (Ipomoea batatas L.) are an important cash crop in the world, and China is the world's largest producer, consumer, and exporter of sweet potatoes, accounting for more than 60% of the world's total production. Sweet potato planting areas are mainly distributed in tropical and subtropical regions, and frequent pests have become the ...Read More -
2022-11-11The usefulness of the eddy flux tower in achieving carbon peaking and carbon neutrality goals at the Dinghushan biosphere reserve as demonstrated by recent important published researchProtection methods for regional forests in southern China .Ecosystem Carbon Exchange Characteristics in the Dinghushan Biosphere Reserve , a Dominant Subtropical Evergreen Forest Ecosystem ” was published in October.We observed seasonal trends in daily ecosystem carbon flux , indicative of sensitivity to climatic factors , such as air temperatu... The eddy flux tower at the Dinghushan biosphere reserve has been a very useful tool especially in measuring long-term carbon sequestration and other important meteorological parameters in the forest. The tower was set up in 2002, and it is the first observation station in a lower subtropical forest established by the Chinese Ecological Research ...Read More -
2022-11-07New research progress on the positive plant-plant interactions over a long-term plant successionUnderstand community change and invasibility .Establishment stage and between native and exotic species .Specifically , positive interactions were more frequent during early establishment and less.Positive interactions involving native species were more frequent than those between exotic species . Positive interactions have been hypothesised to influence plant community dynamics and species invasions. However, their prevalence and importance relative to negative interactions remain unclear to understand community change and invasibility.Read More
