• Scientists Control the Rate of Algal Blooms in Freshwater System

  Recently, researchers in the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) have investigated the allelopathic effects of Myriophyllum aquaticum and its exudate on two typical bloom-forming cyanobacteria, Microcystis aeruginosa and Anabaena flos-aquae under laboratory conditions

• Chinese Herbal Medicine Contributes to the Gastrointestinal Tract Health in the Calves

  Acanthopanax senticosus (AS), a tonic and sedative Chinese herbal medicine, is well known to be highly effective in treating various conditions, including stress-induced pathophysiologic changes and inflammation. AS contains acanthosides, triterpenic saponin, polysaccharide, flavone, senticoside, organic acids, amino acids, vitamins and minerals. Saponin may be responsible for the biological activities of AS.

• Herbivorous Geese were Significantly Influenced by Wintering Habitat Changes in the East Dongting Lake

  Changes in herbivorous goose populations in relation to changes in their wintering habitat are of great concern in the major overwintering region in EAAF. The spatio-temporal evaluation of the waterbird-habitat relationship not only directly reflects the wintering herbivorous goose population pattern and their habitat quality but also promotes the development of wetland management strategies for protecting these valuable species in the middle reaches of the Yangtze River from the effects of human intervention, and in particular, the Three Gorges dam project.

• Will Polyunsaturated Fatty Acids be More Helpful When They are Taken in the Morning?

  A team of researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) studied the daily pattern of PUFA contents and expression of genes related to de novo synthesis of long chain PUFA, with a pig model. The researchers collected blood and liver samples in a day at 3: 00 a.m., 7: 00 a.m., 11: 00 a.m., 15: 00 p.m., 19: 00 p.m., 23: 00 p.m., respectively.

  Global Warming and Extreme weather: are Greenhouse Gases to be Blamed?

  a team of researchers from China Agricultural University, the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) conducted a study to investigate the temporal characteristics of N2O and NO emissions, daily emissions were measured over two and a half years period using static closed-chamber/gas chromatograph and chemiluminescent measurement system in a tea field of subtropical central China.

• Ecological Restoration Projects Show Varying Effectiveness on Long-term Vegetation Dynamics in the Karst Regions of Southwest China

  Researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) and University of Copenhagen combined long-term satellite and statistical data to evaluate the efforts of ERPs on vegetation dynamics across Southwest China in recent decades. Moreover, the project effectiveness (i.e. the relation of invested money and observed efforts) was assessed.

• Anammox Bacterial Abundance, Activity, and Contribution in Constructed Wetland Treating Swine Wastewater

  Researchers in the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) employ quantitative PCR assay, 15N-stable isotope tracing technique, and 16S rRNA clone library to document the distribution, diversity and roles of anammox bacteria in sediments of CWs treating high strength SW.

• Lysine Containing Peptides, a Novel Source of Lysine for Animals

  Prof. YIN Yulong's group in the Institute of Subtropical Agricultural, Chinese Academy of Sciences (ISA) focused on amino acid nutrition for many years and found that dietary lysine restriction impaired intestinal absorption and metabolism.

  Comparison of Soil Carbon Fixation Rates and Autotrophic Population in Three Natural Ecosystems in China

  the research group from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) performed continuous labeling of three typical natural soil types (Wetland, Grassland and Forest) with 14C-CO2 for 15 days. They hypothesized that the physiological strategies for autotrophic microbial growth in these soils vary depending on biogeochemical factors. After 15 days of continuous labeling, the researchers measured the amount of labeled C incorporated into the microbial biomass in these soils. They also evaluated the diversity and abundance of CO2-fixing and CO-oxidizing bacteria by molecular analysis of cbbL and coxL genes, and used this information to estimate the genetic potential of microbial carbon fixation in each ecosystem. They also examined soil physicochemical properties to identify key factors shaping the microbial diversity in these soils.
