  1. Confidence intervals are given in parenthesis. Note that lnL values for the more complex four-parameter model are not superior as shown by a likelihood ratio test (lnLEfbis: −0.54; lnLM7 lysin: −0.45; lnLME−mitotype: −0.003).
  2. aObserved E allele frequency at the West side of the cline (Helgoland).
  3. bObserved E allele frequency at the East side of the cline (Askö).
  4. cThe cline centre is given as the distance from the West side of the cline (Helgoland).
