Book Synopsis Comprehensive Revision of a Worldwide Collection of Freshwater Sponges by : James Theophilus Penney
Download or read book Comprehensive Revision of a Worldwide Collection of Freshwater Sponges written by James Theophilus Penney and published by . This book was released on 1968 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Racek seems to have authored much of this work after the death of J. T. Penney and undertook a study and review of Penny's huge colleciton of material and unpublished data at the recommendation of B. Theodore Cole of the University of South Carolina. In view of the voluminous material available, Racek found it imperative to revise all true gemmule-producing species rather than elaborate Penny's outlined account of the Meyeninae and as a result of the study, demonstrated the fallacy of a subdivision of the family Spongillidae by using gemmosclere characteristics.

Available in PDF, EPUB and Kindle. Book excerpt: "Specimens of freshwater bryozoans (Ectoprocta) and sponges (Porifera: Spongillidae), two of the most poorly known faunal groups in Canada, were obtained from various locations in Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland. A total of 14 species of bryozoans and 15 species of sponges were identified. In 31 cases, these species were recorded from a province for the first time. Species new to Canada include the bryozoans Lophopodella carteri, Plumatella orbisperma, and Pottsiella erecta, and the sponges Radiospongilla crateriformis, Spongilla aspinosa, and Trochospongilla horrida. The morphology, taxonomy, distribution, and ecology of each species are examined. Several taxonomic revisions are made. Eunapius mackayi and Plumatella orbisperma are redescribed. Spongilla heterosclerifera, considered an endangered species, is shown to be a species mixture. Taxonomic keys to Eastern Canadian species of freshwater bryozoans and sponges are presented. New limits of tolerance to pH, calcium and magnesium levels, and water temperature are established for several species." --

This book was released on 2016-09-02 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Comprehensive Revision of a Worldwide Collection of Freshwater Sponges (Porifera, Spongillidae) In spite of the fact that serious scientific efforts in the taxonomic study of freshwater sponges were begun in the mid-19th century, and that a great number of subsequent investigators have contributed a massive amount of additional descriptive information, the taxonomy of this group has remained in a most chaotic state. Following Bowerbank's (1863) initial revision of all species of Spongilla, Gray (1867) was first to establish useful criteria for their generic differen tiation and to erect six new genera in addition to Spongilla Lamarck. Unfortunately, this system was criticized and its validity questioned by Carter (1881a), who claimed that Gray established his new genera without having seen Bowerbank's material upon which they were erected. Although fully unjustified in doing so, Carter (1881a) alto gether ignored Gray's existing generic names and devised his own system for the inclusion of Bowerbank's species and subsequently collected material. Thus it happened that Gray's well-established genera fell into complete obscurity for many decades, and Carter's system became firmly established, Without being seriously challenged by any subsequent taxonomist. From the turn of this century, several attempts were made to revise comprehensively the status of the ever increasing numbers of species. After the publication of the first bibliography of all freshwater sponges by Weltner it was chie y Annandale (1906 - 1919) who began to build the foundations to an improved and modernized knowledge of spongillid taxonomy. Annandale reestablished some of Gray's generic names, at least at a subgeneric level, and added a number of well-defined new genera to the conglomerate systems of Gray and Carter. Additional revisions were subsequently undertaken by Gee (1926 Schroder (1926 and Arndt (1923 to name just the most important contributors. Generic revisions were attempted by De Laubenfels (1936) and Jewell However, in spite of the fact that all these investigations have certainly helped to overcome a number of taxonomic difficulties, they seemed to have little effect on the stability of taxonomic nomenclature.

Our aim is to provide readers with the highest quality reproductions of fiction and non-fiction literature that has stood the test of time. The many thousands of books in our collection have been sourced from libraries and private collections around the world.The titles that Trieste Publishing has chosen to be part of the collection have been scanned to simulate the original. Our readers see the books the same way that their first readers did decades or a hundred or more years ago. Books from that period are often spoiled by imperfections that did not exist in the original. Imperfections could be in the form of blurred text, photographs, or missing pages. It is highly unlikely that this would occur with one of our books. Our extensive quality control ensures that the readers of Trieste Publishing's books will be delighted with their purchase. Our staff has thoroughly reviewed every page of all the books in the collection, repairing, or if necessary, rejecting titles that are not of the highest quality.

Book Synopsis Aspects of Sponge Biology by : Frederick Harrison
Download or read book Aspects of Sponge Biology written by Frederick Harrison and published by Elsevier. This book was released on 2012-12-02 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aspects of Sponge Biology is the result of a symposium about sponge biology held in Albany, New York in May 1975. The symposium not only presents investigations, but also problem areas in the field of sponge biology. This book therefore shows that sponges are a very challenging and untouched subject area for future studies. This book is divided into three major parts, wherein the first part introduces and discusses sponge biology. The introduction and discussion include sponge biology principles, perspectives, and problems. The next two parts discuss cell and development biology, taxonomy, and ecology. Part 2 deals with several topics of the cellular aspect, including an analysis of reproduction in sponge populations and cytochemical studies of connective tissues in sponges. This part also looks into the cytological abnormalities in various normal and transformed cell lines. Part 3 describes the different types of sponge in their various habitats. Sponge feeding mechanisms, ecological factors controlling sponge distribution, and zoogeography of Brazilian marine Demospongiae are also discussed in this part. This book will be of important value to biology students and teachers. Specialists including zoologists, ecologists, comparative physiologists, and biologists will also benefit from this book.
