The Loricariinae belong to the Neotropical mailed catfish family Loricariidae, the most
species-rich catfish family. Among loricariids, members of the Loricariinae are united by a …

Ecological opportunity is often proposed as a driver of accelerated diversification, but
evidence has been largely derived from either contemporary island radiations or the fossil …

Distribution history of the widespread Neotropical genus Hypostomus was studied to shed
light on the processes that shaped species diversity. We inferred a calibrated phylogeny …
