Although invasive species are viewed as major threats to ecosystems worldwide, few such
species have been studied in enough detail to identify the pathways, magnitudes, and …

Phylogenetic analyses indicate that viviparity (live‐bearing reproduction) has originated
independently in more than 150 vertebrate lineages, including a minimum of 115 clades of …

The last species list of the European herpetofauna was published by Speybroeck, Beukema
and Crochet (2010). In the meantime, ongoing research led to numerous taxonomic …

Human activities continue to erode the tree of life, requiring us to prioritize research and
conservation. Amphibians represent key victims and bellwethers of global change, and the …

Habitat loss is the primary driver of biodiversity decline worldwide, but the effects of
fragmentation (the spatial arrangement of remaining habitat) are debated. We tested the …

A phylogenetic analysis of sequences from 503 species of hylid frogs and four outgroup taxa
resulted in 16,128 aligned sites of 19 genes. The molecular data were subjected to a …

Frogs (Anura) are one of the most diverse groups of vertebrates and comprise nearly 90% of
living amphibian species. Their worldwide distribution and diverse biology make them well …

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 extant amphibians are one of the most diverse radiations of terrestrial vertebrates (>
6800 species). Despite much recent focus on their conservation, diversification, and …

Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are
fundamental to nearly every evolutionary model and process. Rates need dates. There is …
