… All point counts were carried out by one of three observers, Nicholas Bayly, Laura Céspedes
and Camila Gómez, having standardised distance estimation and the ability to identify …

We studied the phylogeny, biogeography, and diversification of suboscine passerines in the
genus Scytalopus (Rhinocryptidae), a widespread, species-rich, and taxonomically …

Phylogeographical analyses provide information about the role of evolutionary processes
underlying species diversity of the Neotropical montains. We used mitochondrial DNA …

The high biological diversity of tropical forests has been attributed to various biogeographic
mechanisms promoting diversification. Among these, the riverine barrier hypothesis …

Tropical mountains are biodiversity hotspots. In particular, mountains in the Neotropics
exhibit remarkable beta diversity reflecting species turnover along elevational gradients. …

… Laura Céspedes Arias participated in the design of the study, data collection in the field,
preliminary analyses, extraction of environmental variables from raster layers and figure …

The Bogota Sunangel (Heliangelus zusii) was described based on a historical specimen
lacking locality data as a striking–and potentially extinct– new species of hummingbird more …

The Shining Sunbeam (Aglaeactis cupripennis) is a widespread and relatively common high-elevation
hummingbird in the tropical Andes. Despite this, there is no comprehensive …

Studying processes acting on differentiated populations upon secondary contact, such as
hybridization, is important to comprehensively understand how species are formed and …

The longstanding view of Neotropical mountain uplift as a promoter of species diversification
has become superfluous in the last decades given it would make no sense to suggest …
