a) Among regions (North, Central and South), b) within Northern region (among shelf position: Outer – DAY, YON; Mid: LIZ, NDR; Inner: LIN, MAR) c) within Central region (among shelf position: Outer – MYR, PIT; Mid: BRI, TRU; Inner: ORP). V = Variance component, % = percent variation explained, fixation = Φ_ST and p = significance.
