| Abstrakt: | Abstract: For the needs of proper management, we analysed the mitochondrial haplotype structure of the European ex situ population of Cuban boas. The results showed its extraordinary diversity. We sequenced 96 specimens and detected 25 distinct haplotypes. Besides this haplotype diversity, the results revealed a deep divergence among three principal haplogroups. Bayesian estimates of the divergence time (3.57 and 2.26 Mya) suggest that within the currently only recognized species Chilabothrus angulifer (Bibron, 1843) there are evolutionary lines whose distance corresponds to or is greater than among some other - taxonomically recognized - species of the genus. This indicates that the Cuban boas represent in fact at least two cryptic subspecies or species. Nevertheless, after considering the current state of the ex situ population, given the current knowledge of the phylogeography of Cuban boas and the fact that they inhabit a single large island (and its nearby coastal islands and islets) at present, we recommend to manage the current ex situ population as a whole. |
