Morphological support for placement of the Wing-banded Antbird Myrmornis torquata in the Thamnophilidae (Passeriformes: Furnariides)
Myrmornis torquata has often been considered an intermediate form between the ground antbirds and the typical antbirds. Although molecular phylogenies have consistently placed M. torquata in the Thamnophilidae (typical antbirds), this species has not been the subject of a thorough anatomical study, and no phylogeny based on morphological characters has been published. We undertook a cladistic m...
متن کاملDNA-based identification applied to Thamnophilidae (Passeriformes) species: the first barcodes of Neotropical birds
The “Barcode of Life” Consortium is a worldwide initiative devoted to perform a molecular inventory of Earth’s biodiversity. The Cytochrome Oxidase c subunit I (COI) gene of the mitochondrial DNA (mtDNA) has been successfully used for identification of North American bird species. However, this technique has not been previously employed to Neotropical birds’ identification. Typical antbirds (Th...
متن کاملDNA sequence data reveal a subfamily-level divergence within Thamnophilidae (Aves: Passeriformes).
The Thamnophilidae is a diverse radiation of insectivorous passerine birds that comprises nearly 220 species and is mostly restricted to the lowlands and lower montane forests of the Neotropics. Current classification within Thamnophilidae relies primarily on morphological variation, but recent incorporation of molecular and vocal data has promoted changes at various taxonomic levels. Here we d...
متن کاملSpecies limits in Antbirds (Aves: Passeriformes: Thamnophilidae): an evaluation of Plumbeous Antvireo (Dysithamnus plumbeus) based on vocalizations
Through most of the 20th Century, Dysithamnus plumbeus was considered to comprise three geographically remote subspecies based on plumage: D. p. plumbeus of the lowlands of southeastern Brazil; D. p. leucostictus of the east slope of the Andes from central Colombia to extreme northern Peru; and D .p tucuyensis endemic to the mountains of northern Venezuela. Some recent authors have elevated the...
متن کاملA putative RA-like region in the brain of the scale-backed antbird, Willisornis poecilinotus (Furnariides, Suboscines, Passeriformes, Thamnophilidae)
The memorization and production of song in songbirds share important parallels with the process of speech acquisition in humans. In songbirds, these processes are dependent on a group of specialized telencephalic nuclei known as the song system: HVC (used as a proper name), RA (robust nucleus of arcopallium), LMAN (lateral magnocellular nucleus of the nidopallium) and striatal Area X. A recent ...
