Download or read book Annelida Basal Groups and Pleistoannelida Sedentaria I written by Günter Purschke and published by Walter de Gruyter GmbH & Co KG. This book was released on 2019-03-18 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Marine Plankton written by Claudia Castellani and published by Oxford University Press. This book was released on 2017 with total page 715 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thorough understanding of planktonic organisms is the first step towards a real appreciation of the diversity, biology, and ecological importance of marine life. A detailed knowledge of their distribution and community composition is particularly important since these organisms are often very delicate and sensitive to change, and can be used as early indicators of environmental change. Natural and man-induced modification of the environment can affect both the distribution and composition of plankton, with important ecological and economic impacts. Marine Plankton provides a practical guide to plankton biology with a large geographic coverage spanning the North Sea to the north-eastern Atlantic coast of the USA and Canada. The book is divided into three sections: an overview of plankton ecology, an assessment of methodology in plankton research covering sampling, preservation, and counting of samples, and a taxonomic guide richly illustrated with detailed line drawings to aid identification. This is an essential reference text suitable for senior undergraduate and graduate students taking courses in marine ecology (particularly useful for fieldwork) as well as for professional marine biologists. It will also be of relevance and use to environmental scientists, conservation biologists, marine resource managers, environmental consultants, and other specialised practitioners.

Download or read book The North American Journals of Prince Maximilian of Wied written by Prince Alexander Philipp Maximilian of Wied and published by University of Oklahoma Press. This book was released on 2014-04-09 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Made famous through the paintings of Swiss artist Karl Bodmer, the North American expedition of German naturalist Prince Maximilian of Wied in 1832–34 was the first scientific exploration of the Missouri River’s upper reaches since the epic journey of Lewis and Clark almost thirty years earlier. Maximilian’s journal has never been presented fully in English—until now. This collector’s-quality, oversized volume, the first of a three-volume set, draws on the Maximilian-Bodmer Collection at Joslyn Art Museum in Omaha, Nebraska. The North American Journals offer an incomparable view of the upper Missouri and its Native peoples at a pivotal moment in the history of the American West. This meticulous account, newly translated with extensive modern annotation, faithfully reproduces Maximilian’s 110 drawings and watercolors as well as his own notes, asides, and appendices. Volume I, which covers May 1832 to April 1833, documents Maximilian’s voyage to North America and his first encounters with Indians upon reaching the West. This is an essential resource for nineteenth-century western American history and a work of lasting value. This book is published with the assistance of the National Historical Publications and Records Commission.
