The Black-goggled Tanager (Trichothraupis melanops) is a South American forest species that comprises two disjunct populations in the Atlantic Forest and in the Andes. During visits to natural history museums, we noticed morphological differences between these populations, which led to a taxonomic revision of the species based on plumage patterns a...

The climatic cycles of the Pleistocene affected the distribution of the vegetation of different biomes, determining the distribution and evolution of the associated fauna. Many studies of Atlantic Forest (AF) organisms suggest that the Pleistocene glacial and interglacial cycles have produced demographically stable populations in the forest’s centr...

Tropical forests of Colombia have one of the highest deforestation rates in the world. The humid forest of the Magdalena valley region is one of the ecosystems with the highest risk of landscape transformation, despite being home to many endemic and threatened species. The aim of this study was to evaluate the role of a Peasant Reserve Zone in the...

BIOGEOGRAPHY OF THE GRAN CHACO: NICHE MODELING AND PHYLOGEOGRAPHY OF MICROSPINGUS MELANOLEUCUS (AVES: THRAUPIDAE). The Gran Chaco, which is part of the diagonal of Neotropical open formations, is a fundamental region to test hypotheses of past connections among the Atlantic Forest, the Amazon and the Yungas. The aim of this study was to evaluate wh...

Neotropical humid montane forest (HMF) is divided by landform discontinuities which could limit gene flow among populations. The northern Andes is a complex montane system and an excellent region to compare the role of discontinuities dividing HMFs on the phylogeography of bird species. We study phylogeographic patterns of seven HMF bird species in...

Several of the first avifaunal surveys in Colombia were conducted in the lowland moist forests of the Middle Magdalena Valley, but for decades this region has been understudied. We present results of an avifaunal survey in a zone of Cantagallo, Bolívar, Colombia (Jun–Jul 2019), based on the collection of voucher specimens, associated tissue samples...

This is Supplementary Material of Evolution between forest macrorefugia is linked to discordance between genetic and morphological variation in Neotropical passerines, published at Molecular Phylogenetics and Evolution Volume 149, August 2020, 106849

The central Andean rainforests and the Atlantic Forest are two similar biomes that are fully isolated by xerophytic and open-vegetation regions (the Chaco and Cerrado, respectively). Even though there is evidence suggesting that these rainforests have been connected in the past, their dynamics of connection, the geographic areas that bridged these...

The Atlantic Forest is separated from the Andean tropical forest by dry and open vegetation biomes (Chaco and Cerrado). Despite this isolation, both rainforests share closely related lineages, which suggest a past connection. This connection could have been important for forest taxa evolution. In this study, we used the Saffron-billed Sparrow (Arre...

Background and Aims Oaks (Quercus; Fagaceae) are one of the most diverse and dominant tree groups occupying temperate and subtropical forests in Mexico. Comparative phylogeography analysis was conducted to understand patterns in the evolutionary history of three Mexican oak species (Quercus scytophylla, Q. sideroxyla and Q. hypoleucoides). We also...

The Andes constitute one of the main factors that have promoted diversification in the Neotropics. However, the role of other highland regions in the southern cone of South America has been barely studied. We analyzed the level of endemism in the avifauna of the Central Sierras in Córdoba, a high region in central Argentina, to evaluate the effect...

The effects of global glaciations on the distribution of organisms is an essential element of many diversification models. However, the empirical evidence supporting this idea is mixed, in particular with respect to explaining tropical forest evolution. In the present study, we evaluated the impacts of range shifts associated with Pleistocene globa...

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 effor...

We report on the capture of an adult male Rufous-tailed Attila (Attila phoenicurus) in Mburucuyá National Park, Corrientes, Argentina. This is the first record for this protected area, and also the first record for the province. Records for this species are scarce in Argentina, where it had been registered previously only in Misiones province. Popu...

We explored the phylogeographic patterns of intraspecific diversity in the Red-crowned Ant Tanager (Habia rubica) throughout its continent-wide distribution, in order to understand its evolutionary history and the role of evolutionary drivers that are considered to promote avian diversification in the Neotropics. We sampled 100 individuals of H. ru...

White-crested Elaenia (Elaenia albiceps chilensis) is a Neotropical austral migrant that is sexually monomorphic in plumage. We first determined whether the brood patch and cloacal protuberance are good indicators of an individual's sex by comparing these characters with individuals sexed using molecular techniques. Second, at several localities en...

We studied the phenotypic variation of the Atlantic Forest passerine Xiphorhynchus fuscus (Aves: Dendrocolaptidae) with the broad aim of addressing whether the history and type of forest affected the evolution of endemic taxa. We also tested whether the different subspecies and genetic lineages of X. fuscus could be considered full species. We coll...

The sea turtle Eretmochelys imbricata inhabits tropical waters of all oceans. IUCN considers this species to be critically endangered and its populations are affected by illegal international shell traffic. We present a pioneer research for Colombia and the Tropical Eastern Pacific, since populations located in 1) Parque Nacional Natural Gorgona, 2...
