Large-scale, time-calibrated phylogenies from supermatrix studies have become crucial for
evolutionary and ecological studies in many groups of organisms. However, in frogs (anuran …

Despite the amount of data on different aspects of biodiversity, such as species distributions,
taxonomy, or phylogenetics, there are still significant gaps and biases in the available …

An emerging challenge in interpreting phylogenomic data sets is that concatenation and
multi-species coalescent summary species tree approaches may produce conflicting results …

Although the differentiation of clades at the species level is usually based on a justifiable
and testable conceptual framework, the demarcation of supraspecific boundaries is less …

The Cenozoic topographic development of the Himalaya‐Tibet orogen (HTO) substantially
affected the paleoenvironment and biodiversity patterns of High Asia. However, concepts on …

The species richness in the Neotropics has been linked to environmental heterogeneity and
a complex geological history. We evaluated which biogeographic processes were …

Phylogenetic estimation is, and has always been, a complex endeavor. Estimating a
phylogenetic tree involves evaluating many possible solutions and possible evolutionary …

Continuous field work on mountains in the upper Pastaza watershed, showed an
unexpected cryptic diversity in the recently described Pristimantis anaiae species group …

Amphibians represent a diverse group of tetrapods, marked by deep divergence times
between their three systematic orders and families. Studying amphibian biology through the …
