ABSTRACT Dispersal is a highly variable trait influenced by life history and ecological factors, affecting gene flow when dispersers successfully reproduce. Anadromous salmonids, with their diverse migratory strategies traits, serve as an ideal model for studying dispersal evolution, showcasing significant inter‐ intraspecific variation. Although environmental factors like temperature likely influence propensity, effects remain poorly documented. This study compares patterns population structure in lake whitefish ( Coregonus clupeaformis ) brook charr Salvelinus fontinalis along the subarctic coastline of James Bay, covering four degrees latitude. These species differ size, representing contrasting ends continuum influencing flow. We hypothesised that whitefish, shorter freshwater residency potentially reduced olfactory imprinting, would disperse more frequently than charr. Using low‐coverage whole‐genome sequencing, we found exhibited broader‐scale greater long‐distance capacity Surprisingly, both showed similar rates differentiation levels. However, had effective sizes approximately 10 times larger charr, indicating while common, it results lower Moreover, were northern area, due to colder temperatures, delayed ice break growing seasons. findings yield insights into how variation shape evolution species.
