Limited performance of DNA barcoding in a diverse community of tropical butterflies
TLDR
This work assesses the applicability of DNA barcoding to a diverse community of butterflies from the upper Amazon, using a group with a well-established morphological taxonomy to serve as a reference and recommends the addition of nuclear sequence data. Expand
Mutualistic Interactions Drive Ecological Niche Convergence in a Diverse Butterfly Community
TLDR
The results show that phenotype and ecology are strongly linked and support the idea that mimicry can cause ecological speciation through multiple cascading effects on species' biology, implying that ecological communities are adaptively assembled to a much greater degree than commonly suspected. Expand
Cladistic analysis of the Neotropical butterfly genus Adelpha (Lepidoptera: Nymphalidae), with comments on the subtribal classification of Limenitidini
TLDR
A two‐stage cladistic analysis of 114 characters from adult and immature stage morphology provided phylogenetic hypotheses for the diverse Neotropical nymphalid butterfly genus Adelpha Hübner, confirming the monophyly and indicating several montane Asian species as potential sister taxa for the genus. Expand
Integration of DNA barcoding into an ongoing inventory of complex tropical biodiversity
TLDR
Adding DNA barcoding to the inventory of the caterpillars, their food plants and parasitoids in northwestern Costa Rica has substantially improved the quality and depth of the inventory, and greatly multiplied the number of situations requiring further taxonomic work for resolution. Expand
Testing historical explanations for gradients in species richness in heliconiine butterflies of tropical America
TLDR
The data obtained in the present study, coupled with individual case studies of recently evolved Heliconius species, suggest that the radiation of heliconiine butterflies occurred predominantly on the eastern slopes of the Andes in Colombia, Ecuador, and Peru, as well as in the upper/middle Amazon basin. Expand
Taxonomy: renaissance or Tower of Babel?
Taxonomy, the science of naming and classifying organisms, is the original bioinformatics and a fundamental basis for all biology. Yet over the past few decades, teaching and funding of taxonomy hasExpand
Out of the Andes: patterns of diversification in clearwing butterflies
TLDR
The role of the Andes in the evolution of a diverse Neotropical insect group, the clearwing butterflies, is studied and it is shown that both genera likely originated at middle elevations in the Andean mountains in the Middle Miocene, contrasting with most published results in vertebrates that point to a lowland origin. Expand
A Comprehensive and Dated Phylogenomic Analysis of Butterflies
TLDR
This study overturns prior notions of the taxon's evolutionary history, as many long-recognized subfamilies and tribes are para- or polyphyletic, and provides a much-needed backbone for a revised classification of butterflies and for future comparative studies including genome evolution and ecology. Expand
Strikingly variable divergence times inferred across an Amazonian butterfly ‘suture zone’
TLDR
The data strongly refute a simple hypothesis of simultaneous vicariance and suggest that ongoing parapatric or other modes of differentiation in continuous forest may be important in driving diversification in Amazonia. Expand
