Ancient and present-day sampling of goats in Corsica.

<p>The medieval samples are all located in the archeological site of Rostino, in the northern part of the island. The present-day samples come from 5 different localities identified by numbers on the map.</p

Mitochondrial diversity of Corsican goats compared to world-wide goats diversity.

<p>Ancient (circles) and current (stars) Corsican sequences have been used with 20 sequences of reference corresponding to all haplogroups described up to now <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030272#pone.0030272-Naderi2" target="_blank">[14]</a> to reconstruct a Bayesian phylogenetic tree using a GTR+I+G model of evolution (see text). Only a single sequence by haplotype has been used, so haplotypes in common between medieval and today periods are indicated by both a circle and star. Only posterior probabilities higher than 0.6 are indicated.</p

Genetic diversity parameters.

<p>The different parameters for all datasets (see text) have been computed on a 130 bp fragment of the HVI region of the mitochondrial control region (CR). The values are given with their confidence interval (±) and tests with their p-value (p).</p

Networks generated with CR sequences of Corsican goats from A) medieval samples only or B) combined with present-day samples.

<p>The circles are proportional to the number of sequences obtained and colours indicated the period: yellow corresponds to XII^th century, red to XIV^th century, orange to all medieval and blue to present-day sequences. See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030272#pone-0030272-t001" target="_blank">Table 1</a> for details about haplotypes and archeological samples. Haplotypes indicated in italics are those only observed in Corsica up to now. Haplotype Ha 26 is the only one from the haplogroup C and differs from the closer haplotype by 17 positions that is materialized by a square with this number.</p
