“…The mitochondrial encoded cytochrome b and NADH dehydrogenase subunit 2 (ND2) were amplified for all ingroup and outgroup samples across all taxa and the mitochondrial encoded NADH dehydrogenase subunit 3 (ND3) gene was amplified from all ingroup and outgroup samples except for L. bugunorum. Conserved autosomal nuclear intron loci including introns from a magmas-like protein (12630), phosphotyrosyl phosphatase (14572), and myeloid leukemia factor 2 (23361) described in Backström et al [34], intron 5 from transforming growth factor β2 (TGFB2, [35]) and intron 5 from β-fibrinogen (Fib5, [36]) were also amplified. In cases where primers derived from the available literature failed to amplify all samples we constructed Liocichlaspecific internal primers based on sequence alignments from Liocichla and outgroup sequences.…”

Background: Historically the babblers have been assigned to the family Timaliidae but several recent studies have attempted to rest the taxonomy of this diverse passerine assemblage on a more firm evolutionary footing. The result has been a major rearrangement of the group. A well-supported and comprehensive phylogeny for this widespread avian group is an important part of testing evolutionary and biogeographic hypotheses, especially in Asia where the babblers are a key component of many forest ecosystems. However, the genus Liocichla is poorly represented in these prior studies of babbler systematics. Methods:We used a multilocus molecular genetic approach to generate a phylogenetic hypothesis for all five currently recognized species in the avian genus Liocichla. Multilocus DNA sequence data was used to construct individual gene trees using maximum likelihood and species trees were estimated from gene trees using Bayesian analyses. Divergence dates were obtained using a molecular clock approach. Conclusions:This study supports an origin of the Liocichla occurring sometime prior to the Miocene-Pliocene boundary, a period of significant climatic upheaval in Asia. The biogeographical patterns within the Liocichla mirror those of other birds in the region and allude to common geological and climatic drivers of avian diversification in Asia.

Rapid song divergence leads to discordance between genetic distance and phenotypic characters important in reproductive isolation

The criteria for species delimitation in birds have long been debated, and several recent studies have proposed new methods for such delimitation. On one side, there is a large consensus of investigators who believe that the only evidence that can be used to delimit species is molecular phylogenetics, and with increasing numbers of markers to gain better support, whereas on the other, there are investigators adopting alternative approaches based largely on phenotypic differences, including in morphology and communication signals. Yet, these methods have little to say about rapid differentiation in specific traits shown to be important in reproductive isolation. Here, we examine variation in phenotypic (morphology, plumage, and song) and genotypic (mitochondrial and nuclear DNA) traits among populations of yellow‐rumped tinkerbird Pogoniulus bilineatus in East Africa. Strikingly, song divergence between the P. b. fischeri subspecies from Kenya and Zanzibar and P. b. bilineatus from Tanzania is discordant with genetic distance, having occurred over a short time frame, and playback experiments show that adjacent populations of P. b. bilineatus and P. b. fischeri do not recognize one another's songs. While such rapid divergence might suggest a founder effect following invasion of Zanzibar, molecular evidence suggests otherwise, with insular P. b. fischeri nested within mainland P. b. fischeri. Populations from the Eastern Arc Mountains are genetically more distant, yet share the same song with P. b. bilineatus from Coastal Tanzania and Southern Africa, suggesting they would interbreed. We believe investigators ought to examine potentially rapid divergence in traits important in species recognition and sexual selection when delimiting species, rather than relying entirely on arbitrary quantitative characters or molecular markers.

“…were used to amplify approximately half of the ND2 gene using primers L5758 and H6313 (Sorenson et al . 1999), and the complete β -fib5 with primers FIB5 and FIB6 (Marini & Hackett 2002). PCR products were purified using a QIAQuick PCR kit (Qiagen), and in the case of the mitochondrial product, used as template for direct sequencing using the same primers employed for amplification.…”

A rare case of interspecific hybridization in the tracheophone suboscines: Chestnut‐naped Antpitta Grallaria nuchalis × Chestnut‐crowned Antpitta G. ruficapilla in a fragmented Andean landscape

Based on analyses of variation in plumage, morphometrics, vocalizations, and mitochondrial and nuclear DNA sequences, we document the occurrence of interspecific hybridization between a Chestnut‐naped Antpitta Grallaria nuchalis and a Chestnut‐crowned Antpitta G. ruficapilla in a high‐elevation forest fragment in the Cordillera Central of the Andes of Colombia. One hybrid individual was collected and at least two were recorded singing. The hybrid specimen exhibits a combination of phenotypic traits that exclude other species of antpittas as potential parents, and its vocalizations combine elements of songs of both of its parental species. Genetic analyses demonstrate that the hybrid has G. nuchalis mitochondrial DNA and mixed nuclear DNA with copies corresponding to G. nuchalis and G. ruficapilla alleles, demonstrating that the female parent was G. nuchalis. Hybridization is considered extremely rare in most groups of suboscine passerines, but it may be facilitated when populations are decimated as a consequence of deforestation and habitat fragmentation.
