Concerns about the deleterious effects of missing data may often determine which
characters and taxa are included in phylogenetic analyses. For example, researchers may …

Recent reviews of the construction of large phylogenies have focused on supertree methods
that involve separate analyses of data sets and subsequent integration of the resulting trees …

Two common approaches for estimating phylogenies in species-rich groups are to:(i)
sample many loci for few species (eg phylogenomic approach), or (ii) sample many species …

Background The extant squamates (> 9400 known species of lizards and snakes) are one of
the most diverse and conspicuous radiations of terrestrial vertebrates, but no studies have …

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 …

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

Amphibia comprises over 7000 extant species distributed in almost every ecosystem on
every continent except Antarctica. Most species also show high specificity for particular …

Brachycephaloidea is a monophyletic group of frogs with more than 1000 species
distributed throughout the New World tropics, subtropics, and Andean regions. Recently, the …

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 …

The angiosperm order Malpighiales includes∼ 16,000 species and constitutes up to 40% of
the understory tree diversity in tropical rain forests. Despite remarkable progress in …
