Biodiversity inventories in high gear: DNA barcoding facilitates a rapid biotic survey of a temperate nature reserve
TLDR
This model of rapid generation and dissemination of essential biodiversity data could be followed to conduct regional assessments of biodiversity status and change, and potentially be employed for evaluating progress towards the Aichi Targets of the Strategic Plan for Biodiversity 2011–2020.
Barcoding the butterflies of southern South America: Species delimitation efficacy, cryptic diversity and geographic patterns of divergence
TLDR
This study supported the utility of DNA barcoding for the identification of the butterfly species of Argentina, but also highlighted several cases of both deep intraspecific and shallow interspecific divergence that should be studied in more detail.
Calibrating the molecular clock beyond cytochrome b: assessing the evolutionary rate of COI in birds
TLDR
This study compares the evolutionary rate of COI relative to cyt b across ten different avian orders and suggests that this variation is partially explained by a clear negative relationship between the difference in divergence in these genes and the age of species.
Continental-scale analysis reveals deep diversification within the polytypic Red-crowned Ant Tanager (Habia rubica, Cardinalidae).
TLDR
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.
A test of the riverine barrier hypothesis in the largest subtropical river basin in the Neotropics.
TLDR
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.
Contrasting evolutionary histories in Neotropical birds: Divergence across an environmental barrier in South America
TLDR
The evolutionary histories of Ramphotrigon megacephalum and Pipraeidea melanonota, two passerines with allopatric populations east and west of the OVC that represent different subspecies, are studied to support the fact that the biological attributes of species can make their evolutionary histories idiosyncratic.
Mind the gap! Integrating taxonomic approaches to assess ant diversity at the southern extreme of the Atlantic Forest
TLDR
DNA barcoding is used to characterize the ant diversity of Iguazú National Park, a protected area of the Upper Paraná Atlantic Forest ecoregion, and suggests that the diversity of ants at INP could be between 6% and 10% higher than currently recognized.
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
Molecular phylogenetics and phenotypic reassessment of the Ramphotrigon flycatchers: deep paraphyly in the context of an intriguing biogeographic scenario
TLDR
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.
