A comparative observational study of prokaryotic microbial community dynamics across different Litopenaeus vannamei cultivation systems
Prokaryotic microbial communities serve as critical indicators of ecosystem health within aquaculture. This observational study comparatively analyzes these communities across three commercial *Litopenaeus vannamei* cultivation systems, examining the impact of pond construction, salinity, and water-exchange intensity. Utilizing 16S rRNA amplicon sequencing, researchers documented significant differences in community composition and diversity, revealing a trade-off between stability and potential pathogenic risk. For deeper exploration of coastal ecology, see our related article, "Abundance and physical controls of Mediterranean micro-estuaries."
Microbiome baseline for an Arctic sentinel: spatial patterning of nasal and anal microbiomes in ringed seals
Ringed seals ( *Pusa hispida* ) serve as vital sentinels of Arctic environmental change, yet comprehensive baseline microbiome data across their circumpolar distribution remain limited. This study establishes the first integrated nasal and anal microbiome baseline for this species, profiling microbial communities from 90 free-ranging seals across eight Arctic locations. Results reveal distinct nasal and anal microbiome structures, with latitude influencing anal microbiome diversity. Notably, shifts in bacterial genera—such as increased *Psychrobacter* northward—were observed, offering a valuable reference for future health monitoring.
Spatial and seasonal patterns of taxonomic, functional, and phylogenetic diversity of fish assemblages in island waters of Zhejiang, China: associations with environmental, climatic, and socioeconomic factors
Fish assemblages play a crucial role in maintaining island ecosystem health, yet comprehensive diversity analyses in China’s island waters remain limited. A recent study evaluated taxonomic, functional, and phylogenetic diversity across eight Zhejiang islands, revealing significant variation—with northern islands exhibiting the highest values. Structural equation modeling highlighted a positive relationship between marine environmental factors and diversity (0.675), a negative socioeconomic impact (-0.173), and an indirect, negative climate influence (-0.456).
