Comparative mitogenomics, phylogeny, and biogeography of selected species of <i>Saxicola</i> (Aves, Passeriformes).

ABSTRACT: Saxicola is a genus of insectivorous birds widely distributed across Eurasia and Africa. Their mitochondrial genomes (mitogenomes), classification, phylogeny, and biogeography are underresearched. Here, we sequenced and/or assembled the mitogenomes of S.stejnegeri, S.torquatus, S.maurus, S.rubicolahibernans, S.r.rubicola and S.dacotiae for detailed comparative analysis, integrating them with published mitogenomes of members of Muscicapidae for phylogenetic reconstruction. Additionally, we estimated the divergence times and ancestral ranges for Saxicola using ND2 and Cytb. These mitogenomes, spanning 16,764 bp to 16,804 bp, exhibit typical gene arrangement, AT bias, and A/C skew tendencies. Among the 13 protein-coding gen
