The drivers of tropical speciation
Since the recognition that allopatric speciation can be induced by large-scale reconfigurations of the landscape that isolate formerly continuous populations, such as the separation of continents byExpand

Latitude, elevational climatic zonation and speciation in New World vertebrates
Many biodiversity hotspots are located in montane regions, especially in the tropics. A possible explanation for this pattern is that the narrow thermal tolerances of tropical species and greaterExpand

Evolutionary differentiation in the Neotropical montane region: molecular phylogenetics and phylogeography of Buarremon brush-finches (Aves, Emberizidae).
Studies on Neotropical phylogeography have largely focused on lowland organisms. Because lowland and highland biotas have different histories and are likely affected by different processesExpand

A phylogenetic approach to disentangling the role of competition and habitat filtering in community assembly of Neotropical forest birds.
1. Methods that assess patterns of phylogenetic relatedness, as well as character distribution and evolution, allow one to infer the ecological processes involved in community assembly. AssumingExpand

Ecological speciation along an elevational gradient in a tropical passerine bird?
Local adaptation of populations along elevational gradients is well known, but conclusive evidence that such divergence has resulted in the origin of distinct species in parapatry remains lacking. WeExpand

The origin and maintenance of montane diversity: integrating evolutionary and ecological processes
Determining how ecological and evolutionary processes produce spatial variation in local species richness remains an unresolved challenge. Using mountains as a model system, we outline an integrativeExpand

Molecules, ecology, morphology, and songs in concert: how many species is Arremon torquatus (Aves: Emberizidae)?
The acceptance of the generalized or unified concept of species (i.e. that species are segments of population lineages) implies that an important task for systematists is to focus on identifyingExpand

Non-monophyly and deep genetic differentiation across low-elevation barriers in a Neotropical montane bird (Basileuterus tristriatus; Aves: Parulidae).
Most widespread birds of Neotropical cloud forests exhibit phenotypic variation that is partitioned geographically suggesting allopatric divergence, but little is known about the extent to which suchExpand

Niche-tracking migrants and niche-switching residents: evolution of climatic niches in New World warblers (Parulidae)
Differences in life-history traits between tropical and temperate lineages are often attributed to differences in their climatic niche dynamics. For example, the more frequent appearance of migratoryExpand

No population genetic structure in a widespread aquatic songbird from the Neotropics.
Neotropical lowland organisms often show marked population genetic structure, suggesting restricted migration among populations. However, most phylogeographic studies have focused on speciesExpand
