Phylogenetic analysis has entered the genomics (multilocus) era. For less experienced
researchers, conquering the large number of software programs required for a multilocus …

The mitochondrial cytochrome b (cyt-b) gene is widely used in systematic studies to resolve
divergences at many taxonomic levels. The present study focuses mainly on the utility of cyt …

The turtle family Geoemydidae represents the largest, most diverse, and most poorly
understood family of turtles. Little is known about this group, including intrafamilial …

Background Phylogenies are commonly used to analyse the differences between genes,
genomes and species. Patristic distances calculated from tree branch lengths describe the …

The phylogeny of groups within Gobioidei is examined with molecular sequence data.
Gobioidei is a speciose, morphologically diverse group of teleost fishes, most of which are …

Using the techniques of direct optimization and sensitivity analysis, the phylogenetics of
polychrotid lizards were examined on the basis of both molecular and morphological data …

By use of the technique of direct optimization the phylogenetics of the cis-Andean lizard
genus Tropidurus were examined on the basis of both molecular (ca. 1.04 kb of sequences …

Here we review research over the past quarter century regarding the systematics and
taxonomy of an ancient, popular and economically valuable group of snakes referred to as …

Examples of Müllerian mimicry, in which resemblance between unpalatable species confers
mutual benefit, are rare in vertebrates. Strong comparative evidence for mimicry is found …

Trichoptera are holometabolous insects with aquatic larvae that, together with the
Lepidoptera, make up the Amphiesmenoptera. Despite extensive previous morphological …
