Understanding how introduced species succeed and become widely distributed within non-native areas is 31 critical to reduce the threats posed by them. Our goal was to reconstruct the main invasion routes and 32 invasion dynamics of a global freshwater invader, the red swamp crayfish, Procambarus clarkii, through 33 the analysis of its genetic variability in both native and invasive ranges. 3
