Parasite population differentiation in immigrant and native populations.

Dc—Jost's D for the component population composed of all members of the group. Di—mean pairwise Jost's D between infrapopulations for all members of the group. Dic—mean Jost's D for each infrapopulation in the group compared to the community component population. AE—mean effective allele number. CI 95% determined with 1000 bootstrap replications using the program SPADE. Student's t-test was used to compare group means for these indices.
