The phylogenetic position of entoprocta, ectoprocta, phoronida, and brachiopoda.
Ectoprocts, phoronids and brachiopods are often dealt with under the heading Tentaculata or Lophophorata, sometimes with entoprocts discussed in the same chapter, for example in Ruppert and Barnes (1994). The Lophophorata is purported to be held together by the presence of a "lophophore," a mesosomal tentacle crown with an upstream-collecting ciliary band. However, the mesosomal tentacle crown ...
متن کاملMolecular phylogenetic analyses of Bryozoa , Brachiopoda , and Phoronida Dissertation
Maximum likelihood and Bayesian inference analyses of seven concatenated fragments of nuclear-encoded housekeeping genes indicate that Lophotrochozoa is monophyletic, i.e., the lophophorate groups Bryozoa, Brachiopoda and Phoronida are more closely related to molluscs and annelids than to Deuterostomia or Ecdysozoa. Lophophorates themselves, however, form a polyphyletic assemblage. The hypothes...
متن کاملPhylogenomic analyses of lophophorates (brachiopods, phoronids and bryozoans) confirm the Lophotrochozoa concept.
Based on embryological and morphological evidence, Lophophorata was long considered to be the sister or paraphyletic stem group of Deuterostomia. By contrast, molecular data have consistently indicated that the three lophophorate lineages, Ectoprocta, Brachiopoda and Phoronida, are more closely related to trochozoans (annelids, molluscs and related groups) than to deuterostomes. For this reason...
متن کاملSpiralian phylogenomics supports the resurrection of Bryozoa comprising Ectoprocta and Entoprocta.
Phylogenetic analyses based on 79 ribosomal proteins of 38 metazoans, partly derived from 6 new expressed sequence tag projects for Ectoprocta, Entoprocta, Sipuncula, Annelida, and Acanthocephala, indicate the monophyly of Bryozoa comprising Ectoprocta and Entoprocta, 2 taxa that have been separated for more than a century based on seemingly profound morphological differences. Our results also ...
متن کاملThe Invertebrates. Vol. V. Smaller Coelomate Groups Chaetognatha, Hemichordata, Pogonophora, Phoronida, Ectopracta, Brachiopoda, Sipunculida. The Coelomate Bilateria
This book, with the proposed second volume, is to constitute a 5th edition of the work of the same title by the author's father, W. M. Bayliss. The last edition of that book appeared in 1924, the year of Sir William's death. Since that time his son has become known to students of the medical sciences as co-author of one of the more readable textbooks of human physiology. The ten chapters of the...
