Frequent drought‐flood abrupt alternation (DFAA) events in the Yangtze River Basin (YRB), characterized by complex formation mechanisms and limited predictability, pose a prominent challenge in climate research. A daily‐scale DFAA index is developed to enhance event identification accuracy by coupling dual signals from precipitation and soil moisture in this study. The selected 86 DFAA events from 1961–2023 are classified into...

With the transformation of aquaculture toward green and sustainable development, the research and application of natural feed additives have become a research focus in the field. As two types of green additives with high efficiency and low residue, herbal medicines and probiotics show significant potential in improving the health of fish and enhancing aquaculture benefits.
