Endothermy, ie the endogenous production of metabolic heat, has evolved multiple times
among vertebrates, and several strategies of heat production have been studied extensively …

The family Trichomycteridae is one of the most diverse groups of freshwater catfishes in
South and Central America with eight subfamilies, 41 genera and more than 300 valid …

Background Fish classifications, as those of most other taxonomic groups, are being
transformed drastically as new molecular phylogenies provide support for natural groups …

Our understanding of phylogenetic relationships among bony fishes has been transformed
by analysis of a small number of genes, but uncertainty remains around critical nodes …

Massively parallel DNA sequencing offers many benefits, but major inhibitory cost factors
include:(1) start-up (ie, purchasing initial reagents and equipment);(2) buyin (ie, getting the …

Spiny-rayed fishes (Acanthomorpha) dominate modern marine habitats and account for
more than a quarter of all living vertebrate species. Previous time-calibrated phylogenies …

Classification of the tremendous diversity of ray-finned fishes (Actinopterygii) began with the
designation of taxonomic groups on the basis of morphological similarity. Starting in the late …

Abstract The Cretaceous–Palaeogene (K–Pg) mass extinction is linked to the rapid
emergence of ecologically divergent higher taxa (for example, families and orders) across …

Ultraconserved (UCEs) are popular markers for phylogenomic studies. They are relatively
simple to collect from distantly-related organisms, and contain sufficient information to infer …

Evolutionary innovations are scattered throughout the tree of life, and have allowed the
organisms that possess them to occupy novel adaptive zones. While the impacts of these …
