Cenozoic tectonic evolution in the Tethyan region has greatly changed the landforms and
environment of Eurasia, driving the evolution of animals and greatly affecting the diversity …

Amphibians are a clade of over 8,400 species that provide unique research opportunities
and challenges. With amphibians undergoing severe global declines, we posit that …

Molecular phylogenies have yielded strong support for many parts of the amphibian Tree of
Life, but poor support for the resolution of deeper nodes, including relationships among …

The genus Amolops (“torrent frogs”) is one of the most species-rich genera in Ranidae, with
59 recognized species. This genus currently includes six species groups diagnosed mainly …

Polyploidy has played an important role in evolution across the tree of life but it is still
unclear how polyploid lineages may persist after their initial formation. While both common …

A substantial biotic interchange took place between Gondwanan India and Laurasia
immediately following the India-Eurasia collision. Located just north of the collision zone, the …

Paleotropical clades with largely disjunct distributions are ideal models for biogeographic
reconstructions. The dung beetle genera Grebennikovius Mlambo, Scholtz & Deschodt …

Despite the prevalence of high‐throughput sequencing in phylogenetics, many relationships
remain difficult to resolve because of conflicting signal among genomic regions. Selection of …

Rhacophoridae are one of the most speciose and ecologically diverse families of
amphibians. Resolution of their evolutionary relationships is key to understanding the …

We present new disarticulated cranial elements of the Eocene frog Thaumastosaurus from
several localities in the Phosphorites du Quercy, France, providing novel information about …
