Temporal analysis of mitochondrial control region data (1183 bp) for marine iguana populations from 11 islands.

Data from each island is separated by sampling year (1991/1993 or 2004). FST values represent differentiation between the same population at two time points. Significant FST values (p<0.05) are labelled with an asterisk. H-test simulations were performed in the program DnaSP using both the number of mutations across all sequences (η) and population parameter θ (see Material and Methods). The 95% confidence intervals (CI) of simulated Hd values are reported for both the η- and θ-based simulations. To the right of the 95% CI ranges are p values which signify the location of the observed Hd value on the simulated distribution. Populations where the observed Hd value falls within the lowest 5% of the simulated data have p values in bold. This signifies that a population has lower Hd than expected under a neutral coalescent model.
