The number of nuclear small subunit (SSU) ribosomal RNA (rRNA) sequences for
Nematoda has increased dramatically in recent years, and although their use in constructing …

Squamate reptiles are a major component of vertebrate biodiversity whose crown-clade
traces its origin to a narrow window of time in the Mesozoic during which the main subclades …

TreeSearch is an R package for phylogenetic analysis, optimized for morphological
datasets. Tree search may be conducted using under equal or implied step weights with an …

Early euarthropod evolution involved a major transition from lobopodian-like taxa to
organisms featuring a segmented, well-sclerotized trunk (arthrodization) and limbs …

The Caloplaca saxicola group is the main group of saxicolous, lobed-effigurate species
within genus Caloplaca (Teloschistaceae, lichen-forming Ascomycota). A recent …

We describe the use of the Fréchet mean and variance in the Billera–Holmes–Vogtmann
(BHV) treespace to summarize and explore the diversity of a set of phylogenetic trees. We …

We explored the efficacy of species tree methods at the family level in birds, using the
Australo-Papuan Fairy-wrens (Passeriformes: Maluridae) as a model system. Fairy-wrens of …

Mollusks are the most morphologically disparate living animal phylum, they have diversified
into all habitats, and have a deep fossil record. Monophyly and identity of their eight living …

Even when the maximum likelihood (ML) tree is a better estimate of the true phylogenetic
tree than those produced by other methods, the result of a poor ML search may be no better …

Few botanical studies have explored the potential of nuclear ribosomal DNA (nrDNA) and
mitochondrial DNA (mtDNA) data obtained through genome skimming for phylogeny …
