This book is the fourth in a series of 4 volumes in the Handbook of Zoology series about morphology, anatomy, reproduction, development, ecology, phylogeny and systematics of Annelida. It covers the most typical polychaetes, Phyllodocida, together with certain smaller taxa placed incertae sedis. This volume completes the polychaetous Annelida. Phyllodocida are often vagile, possess well-developed parapodia. Due to their broad and flat cirri these parapodia look like leaves in some taxa and leading to the name of the entire group. Many of its members are macrophagous and often predators. Accordingly most species possess elaborate sense structures such as sensory palps, antennae, eyes and nuchal organs. In certain species the eyes comprise thousands of photoreceptor cells and lenses most likely allowing forming true images. Phyllodocida typically possess an axial muscular pharynx called proboscis functioning as a kind of suction pipe allowing them to swallow and ingest their prey or other food. This pharynx may be armed with cuticular jaws and some species even possess venom glands. The probably most popular and important polychaete model organism, Platynereis dumerilii, belongs to this interesting group. Phyllodocida fall into two to three higher clades comprising about 25 families which represent more than one fourth of the polychaete diversity. One of these families, Syllidae, comprises about 700 valid species of mainly small size and may, therefore, represent one of the most complex and somehow difficult polychaete families on Earth.
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.
This book is the first in a series of 4 volumes in the Handbook of Zoology series about morphology, anatomy, reproduction, development, ecology, phylogeny and systematics of Annelida. This first volume covers members of the so-called basal radiation and the first part of Sedentaria. It is supplemented by chapters on the history of annelid research, their fossil record, and an introduction to the phylogeny of annelids and their position in the tree of life. In the latter chapter the history of their systematic is reviewed giving an almost complete picture of systematic-scientific progress especially in the past years which changed our view on annelid phylogeny dramatically. The most basal annelids, lately united as Palaeoannelida, represent two families of aberrant polychaetes formerly often suggested to be highly derived which now give us a fresh look on how the ancestral annelid may have looked like. These lack certain key characters such as nuchal organs and possess rather simple nervous systems which now likely represent primitive character states. In this basal radiation the first taxon of apparently unsegmented and achaetigerous animals is positioned, the Sipuncula. Most likely another group of platyhelminth-like and unsegmented and even chaeta-lees annelids, Lobatocerebridae falls into this basal radiation. The section of Sedentaria starts with Orbiniida, a taxon characterized by elongated, thread-like worms which do not have anterior appendages like palps and comprises several families representing members of the Meiofauna. These minute worms often inhabiting the interstitial spaces in marine sands are suggested to have evolved by progenesis. The second higher taxon is represented by Cirratuliformia comprising nine families of typical sedentary polychaetes each of which showing a remarkable variation of the annelid body plan. Members of this taxon usually exhibit many annelid characters but certain also lack the most typical prostomial appendages, the palps.
Diese Bild-DVD enthAlt alle Abbildungen aus 2. Auflage des Westheide/Rieger (Hrsg.), "Spezielle Zoologie. Teil 1: Einzeller und Wirbellose Tiere," an denen Spektrum Akademischer Verlag die Rechte hat. Die DVD soll Dozenten, Lehrern und Studierenden der Biologie zur Gestaltung, ErgAnzung und Nachbereitung von Vorlesungen und Seminaren dienen. Die DVD ist WINDOWS-kompatibel inklusive VISTA und lAuft auch auf MAC und Linux.
Der 2. Band der Speziellen Zoologie uber die Schadel- oder Wirbeltiere (Craniota) liegt nun in dritter Auflage vor. 40 Autoren haben die Kapitel grundlich uberarbeitet, aktualisiert und mit einer Reihe neuer oder verbesserter Abbildungen erganzt. Sie beschreiben die Vielfalt dieser Tiergruppe anhand von Bau, Funktion und Leistung ihrer Organsysteme. Der Aufbau des Buches folgt der phylogenetischen Systematik, die Ergebnisse molekularer Verwandtschaftsanalysen wurden dabei berucksichtigt. Die bewahrte Gliederung in einen relativ kurz gefassten Allgemeinen Teil, der die Grundzuge der Organisation dieser Tiergruppe in moderner Sicht darstellt, und einen umfangreichen Speziellen Teil, der die einzelnen Untergruppen detailliert abhandelt, wurde beibehalten. Fur alle Taxa werden einzelne, auch heimische Arten vorgestellt, die phylogenetisch, oekologisch, ethologisch oder wirtschaftlich besonders bedeutend sind. Dieses anspruchsvolle Lehrbuch ist gleichzeitig ein Nachschlagewerk, das Biologen aus unterschiedlichsten Fachrichtungen einen fundierten UEberblick uber die Erscheinungsformen der Wirbeltiere gibt. Es vervollstandigt das von Wilfried Westheide und Reinhard Rieger herausgegebene grosse Lehrbuch Spezielle Zoologie, dessen erster Band uber Einzeller und Wirbellose Tiere seit 2013 in dritter Auflage vorliegt.
Diese 3. Auflage des 1. Teils der „Speziellen Zoologie“ wird weiterhin das maßgebende Lehrbuch der Systematischen Zoologie für Studierende der Biowissenschaften sein. Während die Systematisierung der eukaryotischen Einzeller umfangreiche Umstellungen erforderlich gemacht hat, erreicht die Großgliederung der Metazoa einen hohen Grad an Verlässlichkeit. Die wichtigsten Neuerungen sind die Auftrennung der Protostomia in die Spiralia (=Lophotrochozoa) und Ecdysozoa, die Herausnahme der Acoelomorpha aus den Plathelminthes und ihre Zusammenführung mit Xenoturbella als Xenacoelomorpha sowie die Auflösung der Articulata in Anneliden und Arthropoden mit der Neukonzeptierung der Annelida u.a. durch die Aufnahme auch der unsegmentierten Sipuncula. Auch alle übrigen Kapitel erhielten eine Überarbeitung durch ihre bisherigen Autoren bzw. durch neue Koautoren. Das Abbildungsmaterial wurde verbessert oder ergänzt, darunter die für dieses Lehrbuch charakteristischen Stammbaumschemata.
