Avian diversity in the Neotropics has been traditionally attributed to the effect of vicariant forces promoting speciation in allopatry. Recent studies have shown that phylogeographical patterns shared among codistributed species cannot be explained by a single vicariant event, as species responses to a common barrier depend on the biological attributes of each taxon. The open vegetation corridor (OVC) isolates Amazonia and the Andean forests from the Atlantic Forest, creating a notorious… 
Phylogeography of two Andean frogs: Test of vicariance versus elevational gradient models of diversification
This research used phylogeographic and coalescent analyses of nuclear and mitochondrial DNA sequence data to compare genetic diversity and evolutionary history of two frog species across their shared range in northwestern Argentina, and supports the vicariance model over the elevational gradient model.
Genetic variation in neotropical butterflies is associated with sampling scale, species distributions, and historical forest dynamics
The results show that COI discriminates species well, but that identification success is reduced on average by ~20% as spatial and taxonomic coverage rises, and levels of genetic variation are associated with species' spatial distribution type, a pattern which might reflect differences in their dispersal and colonization abilities.
Evolution between forest macrorefugia is linked to discordance between genetic and morphological variation in Neotropical passerines.
The genetic data rejected the hypothesis of a Chaco connection in the tested species, providing evidence for a connection through the Cerrado or through the transition between the Cermado and Chaco, in a process that could have started as early as the Late Miocene.
A test of the riverine barrier hypothesis in the largest subtropical river basin in the Neotropics.
Comparisons informed by the geological history of the Paraná River and its influence on the ecological and climatic differences among ecoregions in the study area further bolster the finding that responses to this geographic barrier have been species-specific.
Molecular phylogenetics and phenotypic reassessment of the Ramphotrigon flycatchers: deep paraphyly in the context of an intriguing biogeographic scenario
A taxonomic reorganization of the tyrant‐flycatchers is necessary and a biogeographic model for the evolutionary history of Ramphotrigon and Deltarhynchus in South and Middle America over the past 12 million years is proposed.
More than the eye can see: genomic insights into the drivers of genetic differentiation in Royal/Macaroni penguins across the Southern Ocean.
Genetic similarity observed between macaroni and royal penguins suggests they constitute a single evolutionary unit, and the role of environmental factors together with geographic distance in the processes of genetic differentiation between Antarctic and sub-Antarctic waters is highlighted.
Functional Significance of Anatomical Accommodation in the Skull of Common Hoopoe, Upupa Epops (Bucerotiformes, Upupidae)
Modifications of the cranial skeleton of common hoopoe and jaw ligaments consider features of adaptation for probe mechanism, as well as exhibit its phylogenetic relationship with other avian species.
UV sensitive vision in cardinals and tanagers is ubiquitous
ABSTRACT Short wavelength visual sensitivity in birds is determined mostly by the type of photopigment present in the short-wavelength sensitive cone 1 (SWS1) which varies between clades and takes
Diversity of ground‐dwelling ants across three severely threatened South American subtropical forests: are diversity patterns influenced by spatial or climatic variables?
Understanding the spatial distribution of species sheds light on the biogeographical history, offers clues to the drivers of biodiversity and helps guide conservation strategies. In southern South


Nuclear and mitochondrial phylogeography of the Atlantic forest endemic Xiphorhynchus fuscus (Aves: Dendrocolaptidae): biogeography and systematics implications.
Analysis of gene flow and divergence time estimates suggest that the endangered subspecies atlanticus (from northeastern Brazil) can be considered a full species under the general lineage species concept.
The niche and phylogeography of a passerine reveal the history of biological diversification between the Andean and the Atlantic forests.
This study used the Saffron-billed Sparrow as a model to evaluate whether the Andean and the Atlantic forests act as a refugia system, as well as to test for a history of biogeographic connection between them, and proposed to split the studied taxon into two full species.
Genomic variation in a widespread Neotropical bird (Xenops minutus) reveals divergence, population expansion, and gene flow.
It is suggested that even if many traditional diversification hypotheses remain untestable, investigations using genomic datasets will provide greater resolution of species histories in the Neotropics and elsewhere.
A mid‐Pleistocene rainforest corridor enabled synchronous invasions of the Atlantic Forest by Amazonian anole lizards
Findings support that climatic fluctuations provided key opportunities for dispersal and forest colonization in eastern South America through the cessation of environmental barriers and strengthens assertions that biological attributes play a role in responses to shared environmental change.
Biogeographic links between southern Atlantic Forest and western South America: Rediscovery, re-description, and phylogenetic relationships of two rare montane anole lizards from Brazil.
Close phylogenetic relationships between highly disjunct, narrowly-distributed anoles suggest that patches of suitable habitat connected the southern Atlantic Forest to western South America during the Miocene, in agreement with the age of former connections between the central Andes and the Brazilian Shield as a result of Andean orogeny.
The drivers of tropical speciation
It is shown that spatial and temporal patterns of genetic differentiation in Neotropical birds are highly discordant across lineages and are not reconcilable with a model linking speciation solely to landscape change, and the strongest predictors of speciation are the amount of time a lineage has persisted in the landscape and the ability of birds to move through the landscape matrix.
Continental-scale analysis reveals deep diversification within the polytypic Red-crowned Ant Tanager (Habia rubica, Cardinalidae).
The findings suggest that the evolutionary history of H. rubica has been shaped by an assortment of diversification drivers at different temporal and spatial scales resulting in deeply divergent lineages that should be treated as different species.
Ecology Predicts Levels of Genetic Differentiation in Neotropical Birds
This study examines genetic variation in 40 codistributed species of lowland Neotropical rain forest birds that have populations isolated on either side of the Andes, the Amazon River, and the Madeira River to hypothesize that differences in dispersal propensity may explain the observation that understory species contain a significantly greater number of subspecies than do canopy species.
The dual role of Amazonian rivers in the generation and maintenance of avian diversity
The data provide compelling evidence that species turnover across the Rio Negro basin encompasses a mixture of histories, supporting a dual role for Amazonian rivers in the generation and maintenance of biological diversity.
Isolation with asymmetric gene flow during the nonsynchronous divergence of dry forest birds
The results show that even when populations of codistributed species asynchronously diverge, the mode of their differentiation can remain conserved over millions of years.
