  Scientists Decode Weaning Resistance of Chinese Indigenous Piglets

  A research group led by Prof. Xiangfeng Kong from the Institute of Subtropical Agriculture of the Chinese Academy of Sciences systematically investigated the differences in the development of intestinal barrier and the regulatory mechanism of dietary fiber in three different breeds of pigs (Taoyuan black, Xiangcun black, and Duroc), and found that there were differences in intestinal development., Local pig breeds presented stronger resistance to weaning stress than the foreign pig breed.

  Chinese Researchers Issue Critical Warning on Groundwater Flooding Risks

  In a recently letter published in Science, researchers led by Prof. Yunpeng Nie from Huanjiang Observation and Research Station of Karst Ecosystem, the Institute of Subtropical Agriculture of the Chinese Academy of Sciences (ISA), issued a critical warning of the risks of groundwater flooding. They called for comprehensive water management to address groundwater floods effectively. Notably, this is the third time that Science has published a paper related to the karst eco-environment in southwest China.

  Researchers Reveal Complex Soil Micro-food Webs Response to Agricultural Activities

  In a recent study published in Soil Biology and Biochemistry on April 6th, researchers led by Prof. WANG Kelin from the Institute of Subtropical Agriculture of the Chinese Academy of Sciences conducted a seven-year observation and control experiment in a karst region in southern China. To decrease random error, new methods for esearch on how synchronized land-use change (starting at the same time and place) influences soil ecological processes and functions were used. Now, they have revealed the complex process of changes in community composition and energy flow in soil micro-food webs under different agricultural disturbance intensities.

  New Scientific Soil Nutrient Recovery Strategies Helps Vegetation Restoration

  The karst ecosystem is particularly fragile as its unique geological background and high calcium and pH soil conditions determining a distinct nutrient turnover mechanism driven by diazotrophs and arbuscular mycorrhizal fungi (AMF). The researcher group of Prof. Wang Kelin from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences (CAS) conducted an serial investigation to assess the abundance, diversity, and community composition of diazotrophs and AMF in karst moutainous regions of Southwest China, and explored the cooperation among different taxa of diazotrophs and AMF under various vegetation restoration strategies.
