Thermal vulnerability metrics for each O. mykiss population including thermal safety margins (TSM) and functional warming tolerance (FWT). Also included are optimal (TOPT) and pejus (TPEJ) temperatures for AAS, temperatures where FAS = 3 (TFAS3), average critical maxima (CTMAX) at ambient holding temperatures, and maximum stream temperatures measured during this study.
