Singapore grouper iridovirus (SGIV) is one of the major pathogens that pose significant threats to the aquaculture industry. Kaempferol is a flavonoid compound extracted from Illicium verum Hook.f. (star anise), a material that is both edible and used in traditional medicine. In this study, we evaluated the antiviral effects of kaempferol against SGIV in vitro and in vivo, and elucidated the antiviral mechanism. Our study foun...

South America is undergoing an unprecedented drought crisis, threatening water security, ecosystem integrity and socioeconomic stability. While individual extreme drought events are well documented, the temporal evolution and mechanistic drivers of long‐term drought intensification remain poorly understood. Here, we employ the Running Slope Difference (RSD)– t ‐test method to analyse Palmer Drought Severity Index (PDSI) and so...

Loss of plant diversity with increased anthropogenic nitrogen (N) deposition in grasslands has occurred globally. In most cases, competitive exclusion driven by preemption of light or space is invoked as a key mechanism. Here, we provide evidence from a 9‐yr N‐addition experiment for an alternative mechanism: differential sensitivity of forbs and grasses to increased soil manganese (Mn) levels. In Inner Mongolia steppes, incre...
