The distance measures (

(Goldstein

1995) and Nei’s
D
(unbiased for small sample sizes, Nei
1978) were calculated and bootstrapped over loci using
Microsat, the microsatellite distance program (E. Minch,
available from http://hpgl.stanford.edu/projects/microsat/
microsat.html). The unrooted distance matrices were input
into
phylip
(Felsenstein 1993) for neighbour-joining analysis
(Saitou & Nei 1987).
