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.
Climate change-related stressors in aquaculture: modulation of gill microbiota and transcriptome in Atlantic salmon
Climate change poses a significant and escalating threat to aquaculture, particularly through rising temperatures, marine heatwaves, and jellyfish blooms. This study investigates the complex interplay of these stressors on Atlantic salmon (Salmo salar), focusing on gill health. Researchers utilized advanced sequencing techniques to analyze gill microbiota and transcriptome responses following exposure to elevated temperatures and jellyfish. Findings reveal a significant shift in microbial communities, notably increased Streptococcus and Staphylococcus, alongside altered gene expression related to immune response and tissue integrity.
