We estimated local and metapopulation effective sizes (N ^eand meta‐N ^e) for three coexisting salmonid species ( Salmo salar, Salvelinus fontinalis, Salvelinus alpinus ) inhabiting a freshwater system comprising seven interconnected lakes. First, we hypothesized thatN ^emight be inversely related to within‐species population divergence as reported in an earlier study (i.e., F ST : S. salar> S. fontinalis> S. alpinus ). Using the approximate Bayesian computation method implemented in ON e SAMP , we found significant differences inN ^e(N ^eOSMP) between species, consistent with a hierarchy of adult population sizes (N ^e S . salar
