Multi-locus phylogeny of the family Acrocephalidae (Aves: Passeriformes)--the traditional taxonomy overthrown.

We present the first study of the warbler family Acrocephalidae based on one mitochondrial and three nuclear DNA loci, in total approximately 2900 bp, including most or all of the species in three (Acrocephalus, Hippolais and Chloropeta) of the four genera and one species in the fourth genus (Nesillas) in this family. All three genera were suggested to be non-monophyletic, although the non-monophyly of Acrocephalus is not fully convincingly demonstrated. Six major clades were found, which agreed largely with the results from two earlier mitochondrial studies, and for which the names Hippolais, Iduna, Acrocephalus, Calamocichla, Notiocichla and Calamodus have been used. However, the results also revealed some new constellations, due to better resolution of deeper nodes and the inclusion of more taxa. The taxonomic implications are discussed.
