Molecular phylogeny of the Valvatacea (Asteroidea: Echinodermata)
The Valvatacea is one the most ecologically important, taxonomically diverse, and widespread groups of postPalaeozoic (i.e. modern) Asteroidea. Classification within the group has been historically problematic. We present a comprehensively sampled, three-gene (12S, 16S, early-stage histone H3) molecular phylogenetic analysis of the Valvatacea. We include five of the six families within the Paxi...
متن کاملGlobal Diversity and Phylogeny of the Asteroidea (Echinodermata)
Members of the Asteroidea (phylum Echinodermata), popularly known as starfish or sea stars, are ecologically important and diverse members of marine ecosystems in all of the world's oceans. We present a comprehensive overview of diversity and phylogeny as they have figured into the evolution of the Asteroidea from Paleozoic to the living fauna. Living post-Paleozoic asteroids, the Neoasteroidea...
متن کاملMolecular 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...
متن کاملMolecular systematics of some Indo-Pacific asterinids (Echinodermata, Asteroidea): does taxonomy reflect phylogeny?
Asterinid sea-stars represent a cosmopolitan element of the world s shallow marine invertebrate communities. Asterinids are typically pentagonal or stellate in form, with flat ventral surfaces adapted for clinging to hard substrates (Clark and Downey, 1992). Clark (1993) listed 18 genera and 117 species of the Asterinidae worldwide. Rowe and Gates (1995) listed eight genera and 37 species of as...
متن کاملA new species of Xyloplax (Echinodermata: Asteroidea: Concentricycloidea) from the northeast Pacific: comparative morphology and a reassessment of phylogeny
Xyloplax janetae n. sp. is described from the northeast Pacific Ocean. This is the third species recognized for the monogeneric Concentricycloidea. Skeletal structures are elaborated by scanning electron microscopy and compared with those of Xyloplax niedusiformis from New Zealand and Xyloplax turnerae from the Bahamas. Critical-point-dried specimens show fibrous connective tissue emerging from...
