Figure 1. Distribution of intraspecific (white bars) and interspecific (black bars) divergences estimated from the K2P distance for the genes 16S, Cytb and CO1 and for the first part of the Cytb gene.

In several cases a non-null number of occurrences was observed, but this is not apparent on the histograms because of the scale. The symbol “*” indicates a non-null number of occurrences within species, and “+”a non-null number of occurrences between species.
