Slow mitochondrial DNA sequence evolution in the Anthozoa.
COLD-WATER CORALS: THE BIOLOGY AND GEOLOGY OF DEEP-SEA CORAL HABITATS There are more coral species in deep, cold waters than in tropical coral reefs. This broad-ranging treatment is the first to synthesise current understanding of all types of cold-water coral, covering their ecology, biology, palaeontology and geology. Beginning with a history of research in the field, the authors describe.
Introduction Understanding key transitions in animal evolution is dependent in on an accurate evolutionary framework or phylogeny. Molecular phylogenetics greatly informed the study of animal evolutionary relationships during the late 1980s and 1990s and brought about several major changes to the animal tree of life (e.g. Lophotrochozoa, Ecdysozoa). More recently, our understanding of higher.
A recent classification (3) indicated that the large jellyfish of the class Scyphozoa belong to the subclass Scyphomedusae, which comprises three orders: (I) Stauromedusae, benthic and sessile, which resemble polyps and are uncommon in the Mediterranean Sea, (II) Coronatae, characterized by small polyps, often devoid of the medusoid phase, (III) Semaeostomeae and one superorder (Rhizostomoidea.
