Molecular 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 کاملOceanographic conditions and diversity of sea stars (Echinodermata: Asteroidea) in the Gulf of California, México.
Species richness is one of the best indicators of biodiversity. However, there are few investigations on concordance of diversity patterns and environmental settings for marine regions. The objectives of this study were to correlate species richness of shallow water (< 200 m deep) sea stars with key oceanographic factors in the Gulf of California, México, and to predict species richness of Aste...
متن کاملTrophic ecology of deep-sea Asteroidea (Echinodermata) from eastern Canada
Asteroids (sea stars) can be important predators in benthic communities and are often present in ecologically important and vulnerable deep-sea coral and sponge habitats. However, explicit studies on the trophic ecology of deep-sea asteroids are rare. We investigated the diets of seven species of deep-sea asteroid from the bathyal zone of Newfoundland and Labrador, eastern Canada. A multifacete...
متن کاملOntogenetic habitat shift, population growth, and burrowing behavior of the Indo-Pacific beach star, Archaster typicus (Echinodermata; Asteroidea)
Archaster typicus, a common sea star in Indo-Pacific regions, has been a target for the ornamental trade, even though little is known about its population biology. Spatial and temporal patterns of abundance and size structure of A. typicus were studied in the Davao Gulf, the Philippines (125°42.7'E, 7°0.6'N), from February 2008 to December 2009. Specimens of A. typicus were associated with inte...
متن کاملMolecular 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...
