This book was released on 1934 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: "One. A fundamental similarity existing among the complex reproductive systems of the Nudibranchiata is pointed out and a classification is presented based on the extent of primary and secondary bifurcation of the hermaphrodite duct. Four types of system are indicated, any one of which might conceivably be the phylogenetic derivative of any other. 2. The histology and anatomy of the reproductive system in Embletonia fuscata, a typical aeolid, are given, and the functional implications of the existing anatomical relationships discussed. 3. Some phases of the natural history of reproduction in the Nudibranchiata are discussed indicating that the mass migrations supposed to precede and follow spawning probably do not occur"--Page 638
Download or read book Reproduction of Marine Invertebrates V4 written by Arthur Giese and published by Elsevier. This book was released on 2012-12-02 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproduction of Marine Invetebrates, Volume IV Molluscs: Gastropods and Cephalopods describes the wide range of structural complexity and diverse modes of reproduction of gastropods and cephalopods. Each chapter discusses the asexual reproduction, sexual reproduction capacity, and developmental stages of different group of gastropods and cephalopods, including prosobranchia, opisthobranchia, pulmonata, nautiloidea, decapoda, and octopoda. Gastropods are among the most conspicuous sea animals, and species of limpets, snails, and slugs are found in all marine habitats. Cephalopods are active and important marine predators, ranging from archaic nautiloids to more recent pelagic decapods and benthic octopods, which are often considered to be one of the apexes of invertebrate evolution. They are all gonochoric and reproduce only by sexual means. All have intricate courtship behavior and derived developmental patterns. Marine biologists and researchers, scientists, and developmental biologists will find this book invaluable.

Download or read book Current Topics in Comparative Pathobiology written by Thomas C. Cheng and published by Elsevier. This book was released on 2013-10-22 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current Topics in Comparative Pathobiology, Volume 2 covers several areas of pathobiology. The book discusses the biology of trematodes of the genus Paragonimus that occur in the Americas; the milky disease of beetles; and the biochemical exploration in insect pathology. The text describes the application of invertebrate tissue culture to the in vitro study of animal parasites; and the use of hydra-hydramoeba as a model system for the study of epizootic processes. The aspects of the biology of nudibranchs are reviewed, with emphasis on nudibranchs as members of associations, including functional morphology, physiology, utilization of host pigments and nematocysts, life history, behavior, defensive mechanisms, and ecology. Chemists, bacteriologists, parasitologists, invertebrate pathologists, immunologists, and protozoologists will find the book invaluable.

Download or read book Shore Ecology of the Gulf of Mexico written by Joseph C. Britton and published by University of Texas Press. This book was released on 2014-01-07 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: To the casual visitor, the Gulf of Mexico shores offer mainly sun, sand, and sea. Even the standard field guides, focused on one group of animals or plants, barely hint at the wealth and diversity of habitats and species along Gulf shores. Shore Ecology of the Gulf of Mexico, using a “whole habitat” approach, breaks new ground in describing all the conspicuous vascular plants, algae, birds, mammals, mollusks, crustaceans, and other invertebrates for each marine habitat. The area covered begins west of the Mississippi delta in Louisiana and follows the shores west and south to the Yucatan Peninsula in Mexico. Transitions between habitats also receive detailed treatment. The authors discuss changes in flora and fauna that result from differences in climate, shore geology, and patterns of precipitation in the succeeding habitats along the Gulf rim. They include discussion of more than 1,000 species of plants and animals, both on shore and in the near-shore subtidal zone, to give a virtually complete picture of western Gulf coast ecosystems. Excellent line drawings and photographs of over 800 species complement the text. For marine scientists, students, and knowledgeable beachcombers, this is a thorough source on Gulf coast marine life.
