Book excerpt: The present volume contains the results of researches on the Post-Oligocene fossil bryozoa of North America and forms the concluding part of our studies on the Tertiary and Quaternary faunas, those of the Eocene and Oligocene epochs having been published in 1920 under the title of North American Early Tertiary Bryozoa.

Download or read book Reproduction of Marine Invertebrates V2 written by Arthur Giese and published by Elsevier. This book was released on 2012-12-02 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproduction of Marine Invertebrates, Volume II: Entoprocts and Lesser Coelomates focuses on the reproduction of smaller groups of marine metazoans. It is organized into nine chapters; each chapter is devoted to a specific marine metazoan. The asexual and sexual reproduction and developmental stages of entoprocta, tardigrada, priapulida, sipuncula, pogonophora, chaetognatha, hemichordata, tunicata, and cephalochordate are discussed. This book is ideal for marine invertebrate researchers, scientists, and reproduction experts.

Download or read book Phylum Bryozoa written by Thomas Schwaha and published by Walter de Gruyter GmbH & Co KG. This book was released on 2020-11-23 with total page 928 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an account of over 6.000 recent and 15.000 fossil species, phylum Bryozoa represents a quite large and important phylum of colonial filter feeders. This volume of the series Handbook of Zoology contains new findings on phylogeny, morphology and evolution that have significantly improved our knowledge and understanding of this phylum. It is a comprehensive book that will be a standard for many specialists but also newcomers to the field of bryozoology.

Download or read book Species Diversity of Animals in Japan written by Masaharu Motokawa and published by Springer. This book was released on 2016-11-26 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the status quo of the knowledge about the biodiversity in terrestrial, freshwater, and marine animals that live in Japan. Consisting of some 6,800 islands that are arrayed for approximately 3,500 km from north to south, the Japanese archipelago has a complex history in a paleogeographic formation process over time and harbors rich flora and fauna. This work will contribute to establishing a general biogeographic theory in archipelagoes around continental shelves. Facing the ongoing extinction crisis, one of the most important tasks for our generation is to bequeath this precious natural heritage to future generations. As the first step toward this goal, a species list has been compiled through solid, steady alpha-taxonomic work in each taxon. Furthermore, the phylogeography and population genetic structure for each species is elucidated for deeper understanding of the local fauna, the scientific results of which should be the basis for establishing conservation policies and strategies. Also the problem of alien or introduced species is investigated as another threat to the native fauna.Each of the 27 chapters is written by the most active specialist leading the field, thus readers can acquire up-to-date knowledge of the animal species diversity and their formation process of Japanese animals in the most comprehensive form available. This book is recommended for researchers and students who are interested in species diversity, biogeography, and phylogeography.

Download or read book Bryozoan Studies 2004 written by Hugo Moyano and published by CRC Press. This book was released on 2005-04-03 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: A selection of papers presented at the 13th International Conference of the International Bryozoology Association held in Concepción Chile in January 2004 and hosted by the Universidad de Concepción and Universidad Católica de la Santísima Concepción. The topics presented in this volume reflect the diversity of studies on bryozoa with authors from 18 countries. They include investigations in seven thematic areas: ecology and life strategies; recent and fossil faunas of Australia and New Zealand; past and present bryozoans from both Antarctic and Arctic seas; geology and palaeontology of bryozoans from Eurasia and North America; fresh water bryozoans around the world; fossil bryozoans of the Mediterranean and Tethyan realms and evolution and diversity of recent species. This volume represents the newest advances made in bryozoological studies during the last three years, and makes a significant contribution to the literature.

Download or read book Miscellaneous Invertebrates written by Andreas Schmidt-Rhaesa and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-03 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the Handbook of Zoology summarizes "small" groups of animals across the animal kingdom. Dicyemida and Orthonectida are enigmatic parasites, formerly united as "Mesozoa" and their position among the multicellular animals is still not known with certainty. Placozoa are small, flat marine animals which provide important information on metazoan evolution. Comb jellies (Ctenophora) are esthetically fascinating animals which cause considerable discussion about their phylogenetic position. Seisonida are closely related to rotifers and acanthocephalans. Cycliophora were discovered and described as one of the last higher taxa and surprise by their complex life cycle. Kamptozoa (= Entoprocta) are small sessile animals in the sea and sometimes also in freshwater. Arrow worms (Chaetognatha) play an important role as predators in the plankton, but they also include benthic forms. Pterobranchia and acorn worms (Enteropneusta) belong to the deuterostomia and are related to echinoderms. In particular enteropneusts play an important role in understanding deuterostome evolution. These chapters provide up to date reviews of these exiting groups with reference to the important literature and therefore serves as an important source of information.

This book was released on 2013-12-16 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three major aspects that distinguish this book are that (1) it contains the most detailed analysis of the sexual reproduction (oogenesis, fertilization and embryonic incubation) in a particular phylum of the aquatic invertebrates (Bryozoa) ever made; this analysis is based on an exhaustive review of the literature on that topic published over the last 260 years, as well as extensive original histological, anatomical and morphological data obtained during studies of both extant and extinct species; (2) this broad analysis has made it possible to reconstruct the major patterns, stages and trends in the evolution of sexual reproduction in various bryozoan clades, showing numerous examples of parallelisms during transitions from broadcasting to embryonic incubation, from planktotrophic to non-feeding larvae and from lecithotrophy to placentation; corresponding shifts in oogenesis, fertilization and embryonic development are discussed in detail; and (3) the key evolutionary novelties acquired by Bryozoa are compared with similar innovations that have evolved in other groups of marine invertebrates, showing the general trends in the evolution of their sexual reproduction. Ecological background of these innovations is considered too. Altogether these aspects make the monograph an “Encyclopedia of bryozoan sexual reproduction,” offering an integral picture of the evolution of this complex phenomenon.
