Phylogeny, biogeography and systematics of Dysphanieae (Amaranthaceae)

Molecular phylogeny of the Forcipulatacea (Asteroidea: Echinodermata): systematics and biogeography

We present a comprehensively sampled three-gene phylogeny of the monophyletic Forcipulatacea, one of three major lineages within the crown-group Asteroidea. We present substantially more Southern Hemisphere and deep-sea taxa than were sampled in previous molecular studies of this group. Morphologically distinct groups, such as the Brisingida and the Zoroasteridae, are upheld as monophyletic. Br...

Systematics, phylogeny and biogeography of Mesoamerican and Caribbean freshwater gastropods (Cerithioidea: Thiaridae and Pachychilidae)

In this work I reviewed the systematics of two distinct lineages of Mesoamerica and Caribbean freshwater snails within the gastropod superfamily Cerithioidea: Thiaridae Gill, 1871 and Pachychilidae Troschel, 1858. Through comparative analyses of morphological, anatomical and molecular genetic data, I found that the family Thiaridae is represented by the genus Hemisinus in the Greater Antilles. ...

Phylogeny, Systematics and Biogeography of the Genus Panolis (Lepidoptera: Noctuidae) Based on Morphological and Molecular Evidence

The genus Panolis is a small group of noctuid moths with six recognized species distributed from Europe to East Asia, and best known for containing the widespread Palearctic pest species P. flammea, the pine beauty moth. However, a reliable classification and robust phylogenetic framework for this group of potentially economic importance are currently lacking. Here, we use morphological and mol...

Phylogenetic Systematics and Biogeography: Using Cladograms in Historical Biogeography Methods

Phytopythium: molecular phylogeny and systematics

The genus Phytopythium (Peronosporales) has been described, but a complete circumscription has not yet been presented. In the present paper we provide molecular-based evidence that members of Pythium clade K as described by Lévesque & de Cock (2004) belong to Phytopythium. Maximum likelihood and Bayesian phylogenetic analysis of the nuclear ribosomal DNA (LSU and SSU) and mitochondrial DNA cyto...
