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...

Seabed scour seriously endangers the stability of fixed offshore wind turbine foundations, while conventional protection methods suffer from environmental and constructability flaws, and the deepwater deployment dynamics of large-scale permeable frame-type anti-scour structures remain unstudied. To fill this gap, this study deduces the theoretical motion equations for a six-sided twelve-sided permeable protective frame, and co...

Floating offshore production systems play a critical role in offshore resource development, where the structural integrity and operational safety of risers, umbilical cables, and mooring cables are of paramount importance. Focusing on the failure risks of these key components under harsh marine environments, this paper systematically reviews the coupled mechanisms of wave-induced loading, electrochemical corrosion, and materia...
