  1. The results of four tests (FIS test, FST test, corrected Mean Assignment Index test and variance of corrected assignment test; see material and methods and [56] for details) are shown for females (F) and males (M) as sampled in 1991/93 and 2004. Note that none of the tests for both sampling periods provide significant differences (p-value) concerning dispersal of sexes.
