Tropical Africa is home to an astonishing biodiversity occurring in a variety of ecosystems.
Past climatic change and geological events have impacted the evolution and diversification …

True toads of the genus Rhinella are among the most common and diverse group of
Neotropical anurans. These toads are widely distributed throughout South America …

Adaptive radiation is hypothesized to be a primary mechanism that drives the remarkable
species diversity and morphological disparity across the Tree of Life. Tests for adaptive …

Taxa with vast distribution ranges often display unresolved phylogeographic structures and
unclear taxonomic boundaries resulting in hidden diversity. This hypothesis-driven study …

Amphibians, and anurans in particular, show the highest diversity of reproductive modes
among tetrapods. Nevertheless, viviparity is scarce in anurans and its occurrence is even …

Endeavours in species discovery, particularly the characterisation of cryptic species, have
been greatly aided by the application of DNA molecular sequence data to phylogenetic …

How evolutionary novelties evolve is a major question in evolutionary biology. It is widely
accepted that changes in environmental conditions shift the position of selective optima, and …

African pygmy toads of the genus Poyntonophrynus are some of the least known species of
African toads. The genus comprises ten recognized species endemic to sub-Saharan Africa …

Although the importance of biogeography in the speciation process is well recognized, the
fundamental role of geographic diversification during adaptive radiations has not been …

Aim There has been recent interest in the origin and assembly of continental biotas based
on densely sampled species‐level clades, however, studies from African freshwaters are …
