“…Studies in the mountains of South and Central America, hosting the richest avian diversity in the world, show that closely related lineages (e.g., sister taxa) are not found in different habitats along elevational gradients as would be expected under a sympatric speciation model. Instead, they are found in similar environments on different parts of single mountain ranges or on different ranges (Chaves and Smith 2011; Barrera-Guzmán et al 2012; Gutiérrez-Pinto et al 2012); these patterns suggest allopatric divergence. A similar pattern occurs in Africa, where studies of a variety of lineages (avian and non-avian) indicate that sister taxa are not co-distributed on single mountains (Voelker et al 2010).…”

Mountains host greater avian diversity than lowlands at the same latitude due to their greater diversity of habitats stratified along an elevation gradient. Here we test whether this greater ecological heterogeneity promotes sympatric speciation. We selected accentors (Prunellidae), an avian family associated with mountains of the Palearctic, as a model system. Accentors differ in their habitat/elevation preferences and south-central Siberia and Himalayan regions each host 6 of the 13 species in the family. We used sequences of the mtDNA ND2 gene and the intron 9 of the Z chromosome specific ACO1 gene to reconstruct a complete species-level phylogeny of Prunellidae. The tree based on joint analysis of both loci was used to reconstruct the family's biogeographic history and to date the diversification events. We also analyzed the relationship between the node age and sympatry, to determine the geographic mode of speciation in Prunellidae. Our data suggest a Miocene origin of Prunellidae in the Himalayan region. The major division between alpine species (subgenus Laiscopus) and species associated with shrubs (subgenus Prunella) and initial diversification events within the latter happened within the Himalayan region in the Miocene and Pliocene. Accentors colonized other parts of the Palearctic during the Pliocene-Pleistocene transition. This spread across the Palearctic resulted in rapid diversification of accentors. With only a single exception dating to 0.91 Ma, lineages younger than 1.5 Ma are allopatric. In contrast, sympatry values for older nodes are >0. There was no relationship between node age and range symmetry. Allopatric speciation (not to include peripatric) is the predominant geographic mode of speciation in Prunellidae despite the favorable conditions for ecological diversification in the mountains and range overlaps among species.

In fact, recent analyses based on multilocus data confirmed six phylogroups in Adelomya (Chaves & Smith ; Chaves et al . ); our samples correspond to clades D and F described in Chaves & Smith () the former clade being restricted to the northern section of the Eastern Cordillera in Colombia.…”

Colombia is the country with the largest number of bird species worldwide, yet its avifauna is seriously threatened by habitat degradation and poaching. We built a DNA barcode library of nearly half of the bird species listed in the CITES appendices for Colombia, thereby constructing a species identification reference that will help in global efforts for controlling illegal species trade. We obtained the COI barcode sequence of 151 species based on 281 samples, representing 46% of CITES bird species registered for Colombia. The species analysed belong to nine families, where Trochilidae and Psittacidae are the most abundant ones. We sequenced for the first time the DNA barcode of 47 species, mainly hummingbirds endemic of the Northern Andes region. We found a correct match between morphological and genetic identification for 86-92% of the species analysed, depending on the cluster analysis performed (BIN, ABGD and TaxonDNA). Additionally, we identified eleven cases of high intraspecific divergence based on K2P genetic distances (up to 14.61%) that could reflect cryptic diversity. In these cases, the specimens were collected in geographically distant sites such as different mountain systems, opposite flanks of the mountain or different elevations. Likewise, we found two cases of possible hybridization and incomplete lineage sorting. This survey constitutes the first attempt to build the DNA barcode library of endangered bird species in Colombia establishing as a reference for management programs of illegal species trade, and providing major insights of phylogeographic structure that can guide future taxonomic research.

“…Further complicating historical biogeographic inference, phylogeographic studies of widespread Andean bird species have identified surprising geographic patterns of genetic relationships which suggest that, despite the linearity of geographic range in these species, neighbouring populations may not always be one another's closest relatives (Weir et al . ; Chaves & Smith ; Gutiérrez‐Pinto et al . ).…”

“…However, phylogeographic studies of humid‐forest Andean organisms that have inferred genetic leapfrog patterns have been based either on single locus data (mtDNA) or on a small number of loci, and nodes suggesting leapfrog relationships have not always been well supported (e.g. Chaves & Smith ; Gutiérrez‐Pinto et al . ).…”

Inferring speciation history in the Andes with reduced‐representation sequence data: an example in the bay‐backed antpittas (Aves; Grallariidae; Grallaria hypoleuca s. l.)

In the Andes, humid-forest organisms frequently exhibit pronounced genetic structure and geographic variation in phenotype, often coincident with physical barriers to dispersal. However, phylogenetic relationships of clades have often been difficult to resolve due to short internodes. Consequently, even in taxa with well-defined genetic structure, the temporal and geographic sequences of dispersal and vicariance events that led to this differentiation have remained opaque, hindering efforts to test the association between diversification and earth history and to understand the assembly of species-rich communities on Andean slopes. Here, we use mitochondrial DNA and thousands of short-read sequences generated with genotyping by sequencing (GBS) to examine the geographic history of speciation in a lineage of passerine birds found in the humid forest of the Andes, the 'bay-backed' antpitta complex (Grallaria hypoleuca s. l). Mitochondrial DNA genealogies documented genetic structure among clade but were poorly resolved at nodes relevant for biogeographic inference. By contrast, relationships inferred from GBS loci were highly resolved and suggested a biogeographic history in which the ancestor originated in the northern Andes and dispersed south. Our results are consistent with a scenario of vicariant speciation wherein the range of a widespread ancestor was fragmented as a result of geologic or climatic change, rather than a stepping-stone series of dispersal events across pre-existing barriers. However, our study also highlights challenges of distinguishing dispersal-mediated speciation from static vicariance. Our results further demonstrate the substantial evolutionary timescale over which the diverse biota of the Andes was assembled.
