  1. In this table, net selection differentials (ie selection differential values for Höje Å minus those for Klingavälsån) for eight morphological traits are shown. Raw data are presented in Table 1. Significance tests for trait differences between populations were obtained from an MANOVA. Symbols:
  2. ***=P<0.001.
  3. **=P<0.01.
  4. =P<0.05.
  5. =P<0.10. Significant differences in trait means (P<0.05) are indicated in bold.
