This book was released on 1989 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A cladistic analysis is conducted, encompassing a series of hierarchical levels within the Sabellidae-Caobangiidae-Sabellongidae complex. Generic relationships within this complex are examined using 36 genera and 43 characters. Outgroup comparisons with the Serpulidae s.s. and Spirorbidae are initially suggested. It is argued, however, that maintaining the Spirorbidae results in the Serpulidae being paraphyletic. Therefore, the Serpulidae s.l. (including spirorbids) are used as the outgroup. The possibility of using the Terebellomorpha (= Terebellida) as an outgroup is discussed. The more inclusive relationship between the orders Sabellida and Spionida is examined, leading to the conclusion that the Spionida is paraphyletic by way of recognizing the Sabellida. Sixteen most parsimonious cladograms are found, differing only slightly in the placement of some genera. Caobangia Giard and Sabellonga Hartman, representing the monotypic Caobangiidae and Sabellongidae, respectively, fall within the Sabellidae. In order to define the Sabellidae as monophyletic, Caobangia and Sabellonga must be placed in this family. Present sabellid subfamilies are either paraphyletic or polyphyletic, except for the monotypic Myxicolinae. Revised monophyletic subfamilies are suggested, comprising a more restricted Fabriciinae and expanded Sabellinae. Caobangia is placed into the former subfamily, while Sabellonga is moved to the latter. The Myxicolinae is not recognized, with Myxicola Koch in Renier being placed in the Sabellinae. Genera of the revised Sabellidae are reviewed in light of the characters used in the cladistic analysis. Several genera are poorly defined in terms of monophyly (e.g., Oriopsis Caullery and Mesnil, Jasmineira Langerhans), while six genera are not defined by synapomorphies: Chone Kröyer, Sabellastarte Kröyer, Perkinsiana Knight-Jones, Pseudopotamilla Bush, Eudistylia Bush, and Schizobranchia Bush. Setal transformation series are discussed, suggesting the presence of regulatory mechanisms localized within a particular body region or operating throughout the thorax and abdomen. Such mechanisms appear to allow for considerable structural lability, resulting in convergence of thoracic and abdominal setal forms from different plesiomorphic states. In some cases, it also appears as though abdominal setal forms may be controlled by segment age and location along the body. Changes in thoracic or abdominal setal forms in notopodia and neuropodia within a particular segment appear to be independent of one another"--P. 4.

This book was released on 2013-06-29 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: In July 2001 experts from all around the world met in Reykjavik, Iceland to discuss various issues of polychaete biology. In particular the latest developments in cladistic inference of polychaete phylogeny were presented. Some studies applied recent molecular techniques, revealing unknown genetic relationships between the different families of polychaetous annelids. This volume is of interest to specialists and students seeking an introduction to the latest developments in the field of systematics and ecology of polychaetous annelids. This book is one in a series presenting results from the International Polychaete conferences.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the second volume in a series of 4 volumes in the Handbook of Zoology series treating morphology, anatomy, reproduction, development, ecology, phylogeny, systematics and taxonomy of polychaetous Annelida. In this volume a comprehensive review of a few more derived higher taxa within Sedentaria are given, namely Sabellida, Opheliida/Capitellida as well as Hrabeiellidae. The former comprise annelids possessing a body divided into two more or less distinct regions or tagmata called thorax and abdomen. Here two groups of families are united, the spioniform and sabelliform polychaetes. Especially Spionidae and Sabellidae are speciose families within this group and represent two of the largest annelid families. These animals live in various types of burrows or tubes and all possess so-called feeding palps. In one group these appendages are differentiated as grooved feeding palps, whereas in the other they may form highly elaborated circular tentacular crowns comprising a number of radioles mostly giving off numerous filamentous pinnulae. Often additionally colourful, the latter are also received the common names "feather-duster worms", "flowers of the sea", "Christmas-tree worms". Opheliida/Capitellida including five families of truly worm-like annelids without appendages represents the contrary. Their members burrow in soft bottom substrates and may be classified as non-selective deposit feeders. Molecular phylogenetic analyses have shown that Echiura or spoon worms, formerly regarded to represent a separate phylum, are members of this group. Last not least Hrabeiellidae is one out of only two families of oligochaete-like terrestrial polychaetes and for this reason received strong scientific interest.

The ever increasing interest in work in oceanography and marine biology and its relevance to global environmental issues, especially global climate change and its impacts, creates a demand for authoritative reviews summarizing the results of recent research. OMBAR has catered to this demand since its foundation more than 50 years ago. Following the favourable reception and complimentary reviews accorded to all the volumes, Volume 56 continues to regard the marine sciences—with all their various aspects—as a unity. Physical, chemical, and biological aspects of marine science are dealt with by experts actively engaged in these fields, and every chapter is peer-reviewed by other experts working actively in the specific areas of interest. The series is an essential reference text for researchers and students in all fields of marine science and related subjects, and it finds a place in libraries of universities, marine laboratories, research institutes and government departments.

Available in PDF, EPUB and Kindle. Book excerpt: The Fourth Edition of The Light and Smith Manual continues a sixty-five-year tradition of providing to both students and professionals an indispensable, comprehensive, and authoritative guide to Pacific coast marine invertebrates of coastal waters, rocky shores, sandy beaches, tidal mud flats, salt marshes, and floats and docks. This classic and unparalleled reference has been newly expanded to include all common and many rare species from Point Conception, California, to the Columbia River, one of the most studied areas in the world for marine invertebrates. In addition, although focused on the central and northern California and Oregon coasts, this encyclopedic source is useful for anyone working in North American coastal ecosystems, from Alaska to Mexico. More than one hundred scholars have provided new keys, illustrations, and annotated species lists for over 3,500 species of intertidal and many shallow water marine organisms ranging from protozoans to sea squirts. This expanded volume covers sponges, sea anemones, hydroids, jellyfish, flatworms, polychaetes, amphipods, crabs, insects, snails, clams, chitons, and scores of other important groups. The Fourth Edition also features introductory chapters on marine habitats and biogeography, interstitial marine life, and intertidal parasites, as well as expanded treatments of common planktonic organisms likely to be encountered in near-to-shore shallow waters.

This book was released on 2006-03-30 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as Siboglinidae), Echiura, Myzostomida and perhaps Sipuncula, are most probably nothing else than greatly modified Annelida. The extreme morphological diversity found especially in Polychaeta displays the plasticity of a simple segmented organisation that basically is nothing else but a serial repetition of identical units. Thus, annelids are highly important to our understanding of fundamental questions about morphological and adaptive diversity, as well as clarifying evolutionary changes and phylogenetic relationships. The book aims to summarize our knowledge on Polychaetes polychaetes and their allies and gives an overview of recent advances gained by studies that employed conventional and modern methods plus, increasingly and importantly, the use of molecular markers and computer-assisted kinship analyses. It also reflects the state of art in polychaete sciences and presents new questions and controversies. As such it will significantly influence the direction of research on Polychaeta and their related taxa.
