Distinct gut microbial communities and functional predictions in divergent ophiuroid species: host differentiation, ecological niches, and adaptation to cold-water habitats
ABSTRACT Gastrointestinal microorganisms play a crucial role in host survival and adaptation, but information on host-specific selection or environmental factors that shape the microbiome in natural populations is limited.In this study, we employed 16S rRNA gene amplicon sequencing to investigate the composition and predicted the functions of gut m
