Recently, I carried out a molecular analysis on a gobiid fish through the use of sequences of the mitochodrial control region. I assessed the fit of our mismatch distributions with the expected models of demographic (Rogers et al., 1992) and spatial (Excoffier, 2004) expansions , by using Arlequin. Unexpectedly, results were consistent with the occurrence of spatial but not demographic expansion. Are there similar instances of inconsistency of these two analyses that are published in scientific literature? I couldn't find anything after a quick search.
