The Amazonian rainforest is arguably the most species-rich terrestrial ecosystem in the
world, yet the timing of the origin and evolutionary causes of this diversity are a matter of …

Electroreception, the capacity to detect external underwater electric fields with specialised
receptors, is a phylogenetically widespread sensory modality in fishes and amphibians. In …

The fish faunas of continental South and Central America constitute one of the greatest
concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living …

The unparalleled biodiversity found in the American tropics (the Neotropics) has attracted
the attention of naturalists for centuries. Despite major advances in recent years in our …

Is there only one electric eel species? For two and a half centuries since its description by
Linnaeus, Electrophorus electricus has captivated humankind by its capacity to generate …

Resolving patterns of ancient and rapid diversifications is one of the most challenging tasks
in evolutionary biology. These difficulties arise from confusing phylogenetic signals that are …

This study provides the most comprehensive Model-Based Total Evidence (MBTE)
phylogenetic analyses of the clade Gymnotiformes to date, reappraising relationships using …

The genetic basis of parallel innovation remains poorly understood due to the rarity of
independent origins of the same complex trait among model organisms. We focus on two …

Classification, phylogeography and the testing of evolutionary hypotheses rely on correct
estimation of species phylogeny. Early molecular phylogenies often relied on mt DNA alone …

One of the most remarkable examples of convergent evolution among vertebrates is
illustrated by the independent origins of an active electric sense in South American and …
