Complete mitochondrial genome of the Ruff , Calidris pugnax (Aves, Scolopacidae)

Abstract

This paper reports the mitochondrial genome of Calidris pugnax, which is a closed circular molecule of 16,902 bp. The overall base composition of this species is 25.2% T, 30.6% C, 32.0% A, and 12.2% G, with an A + T content of 55.2%. The structure of the mitogenome is a typical vertebrate mitochondrial gene arrangement. Phylogenetic analysis of complete mitochondrial genome concatenated sequences from 13 species from 6 genera was conducted using the maximum-likelihood (ML) model. The topology demonstrated that the mitogenome of this species was genetically closest to that of Calidris tenuirostris. Calidris pugnax mitogenome can contribute to our understanding of the phylogeny and evolution of this species.
