Principal component analysis (PCA) performed on 19 bioclimatic variables extracted from the Worldclim database [54] for <i>Ceratitis fasciventris</i> occurrences (see Table 2 for symbol meanings).

<p>These multivariate analyses draw the bioclimatic envelopes of the different phylogeographic lineages belonging to <i>C</i>. <i>fasciventris</i>. Circles of correlation (a) and factorial scores of records (b) are shown. Percentages of variance explained by each PCA axis are indicated in correlation circle.
