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...

Trophic 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...
