Complete Mitochondrial Genomes of and with Phylogenetic Analysis of Charadriiformes
Overview
Affiliations
Background: Plovers (Charadriidae), within the order of Charadriiformes, a group of modern birds distributed worldwide, are a frequent subject of molecular phylogenetic studies. While research on mitochondrial genome (mitogenome) variation within the family Charadriidae, especially intraspecific variation, is limited. Additionally, the monophyly of and the phylogenetic placement of remain contentious. Nevertheless, recent studies utilizing complete mitogenomes from available databases to construct phylogenetic trees for Charadriidae and Charadriiformes remain scarce.
Methods: This study aims to explore mitogenome variation within and clarify the phylogenetic placement of We sequenced the complete mitogenome of six and one , and all additional available mitogenomes were integrated within Charadriiformes. The average complete mitogenome length of is 16,889 bp, and is 16,859 bp.
Results: Our results support the suggestion that the monophyly of and is nested within Charadriidae. The phylogenetic analysis of Charadriiformes based on mitogenomes strongly supports the recognition of three major shorebird clades: Charadrii, Lari and Scolopaci, with Lari and Scolopaci identified as sister clades.
Conclusions: Our study reinforces the credibility of the inferred evolutionary relationships within Charadriidae and Charadriiformes.
