The Chinese sturgeon ( Acipenser sinensis ) and Yangtze sturgeon ( A. dabryanus ) are critically endangered flagship species. To investigate the intestinal microbial changes associated with bacterial enteritis in captive populations, we integrated bacterial isolation with metagenomic sequencing to characterize both healthy and maladjusted gut microbiomes. Healthy sturgeons exhibited a stable microbiota dominated by the benefic...

A central aim of community ecology is to understand how local species diversity is shaped. Agricultural activities are reshaping and filtering soil biodiversity and communities; however, ecological processes that structure agricultural communities have often overlooked the role of the regional species pool, mainly owing to the lack of large datasets across several regions. Here, we conducted a soil survey of 941 plots of agric...
