Serial sampling reveals temperature associated response in transcription profiles and shifts in condition and infectious agent communities in wild Atlantic salmon
Abstract Anadromous Atlantic salmon ( Salmo salar ) populations have declined across their Southern distributions in North America. While river temperature has been identified as a central factor influencing migration behavior and over‐winter survival, little research has addressed the prevalence of...
