  Precipitation Sensitivity Thresholds Clarified for Vegetation Growth in Karst

  Large-scale ecological projects have significantly “greened” the karst region in Southwest China over the past 20 years. However, the fragile geological setting, the frequent occurrence of extreme droughts in recent years, in the context of global climate change, has increased uncertainty and risk in the recovery and growth of vegetation.

  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.

  New Study Uncovers How Microbial Metabolic Capacity Regulates Mineral-Associated Organic Carbon Accrual in Subtropical Paddy Soils

  In the most recent study published in Soil Biology and Biochemistry on May 27th, researchers led by Prof. Wu Jinshui from the Institute of Subtropical Agriculture, Chinese Academy of Science , collected subtropical paddy soil samples along the organic C gradient ranging from 4.0 to 40.1 g kg-1 to investigate the relationship between MAOC accrual and microbial metabolism using a combination of size fractionation, 18O-H2O incubation, and biomarker techniques analyses.

  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.
