Diversity measures for the studied populations of Styela plicata.

Number of individuals analyzed per population (N). Allelic richnesstandarized across populations (r), Gene (Hd) and nucleotidic (π) diversity, and their corresponding standard deviations in brackets. Number of alleles per population (Nh), with private alleles shown in brackets. Inbreeding coefficient (Fis) for ANT. Asterisks represent significant coefficients at PHexp represents the expected heterozygosity and Hobs represents the observed heterozygosity.
