Winging it: Unveiling how hummingbirds alter their flying kinematics during molt.

This study examines how molting affects hummingbird flight kinematics by comparing wing movements in molting and non-molting individuals.

Adaptive variation in avian eggshell structure and gas conductance across elevational gradients?

The paper examines how avian eggshell structure and gas conductance vary with elevation, finding reduced conductance and structural changes across species.

Allochronic Divergence Driven by Spatial Asynchrony in Precipitation in Neotropical Frogs?

This study examines how spatial asynchrony in precipitation affects genetic divergence in Neotropical frogs, finding a positive association with genetic differentiation but not with species richness or speciation rates.

Repeated colonization of caves leads to phenotypic convergence in catfishes (Siluriformes: Trichomycterus) at a small geographical scale

This study shows that cave-dwelling catfishes in the genus Trichomycterus in Colombia have been independently colonized by two separate clades, leading to phenotypic convergence despite different colonization events.

An extinct hummingbird species that never was: a cautionary tale about sampling issues in molecular phylogenetics

The paper reanalyzes mitochondrial DNA data to challenge the status of Heliangelus zusii as a distinct species, suggesting it may result from hybridization with Aglaiocercus kingii.

Atlantean Evolution in Darwin’s Finches—Issues and Perspectives in Species Delimitation using Phenotypic Data

The paper reanalyzes morphological data from Darwin’s ground-finches using normal mixture models to assess species delimitation, finding support for multiple species over the claim of no distinct species.

Origin and cross-century dynamics of an avian hybrid zone

The paper analyzes the origin and temporal dynamics of an avian hybrid zone between tanagers in Colombia, finding it likely originated from secondary contact and shows recent shifts in position and width.
