Abstract

The paper reports the whole mitochondrial genome (approximately 13 kb) sequencing in three individual representatives of the continental population of Blakiston’s fish owl Bubo blakistoni (Seebohm 1884), the IUCN Red List species in the family Strigidae. The analysis revealed extremely low mtDNA genetic diversity, which may be indicative of the critical state of the studied population. The phylogenetic analysis performed on the basis of the whole mitochondrial genome sequencing data showed that Blakiston’s fish owl is more closely related to the Strix genus than to the Bubo genus with the genetic divergence between blakistoni and either of the two genera being statistically significant and close to intergeneric level (p-distance of 0.135 in the case of the Strix genus and p-distance of 0.151 in the case of the Bubo genus). The results obtained in this work do not match the published data on the mitochondrial cytochrome b gene and the nuclear RAG-1 gene, which laid the basis for the assignment of Blackiston’s fish owl to the Bubo genus in the recent taxonomic bulletins, but rather support the earlier taxonomic classification according to which all four Asian forms, blakistoni, flavipes, zeylonensis, and ketupu, constituted a separate Ketupa genus.
