The Mollusks


Book Description

Mollusks have been important to humans since our earliest days. Initially, when humans were primarily interested in what they could eat or use, mollusks were important as food, ornaments, and materials for tools. Over the centuries, as human knowledge branched out and individuals started to study the world around them, mollusks were important subjects for learning how things worked. In this volume, the editors and contributors have brought together a broad range of topics within the field of malacology. It is our expectation that these topics will be of interest and use to amateur and professional malacologists.

Invertebrate Histology


Book Description

The first comprehensive reference to invertebrate histology Invertebrate Histology is a groundbreaking text that offers a comprehensive review of histology in invertebrates. Designed for use by anyone studying, diagnosing, or researching invertebrates, the book covers all major taxonomic groups with details of the histologic features, with color photographs and drawings that clearly demonstrate gross anatomy and histology. The authors, who are each experts in the histology of their respective taxa, bring together the most recent information on the topic into a single, complete volume. An accessible resource, each chapter focuses on a single taxonomic group with salient gross and histologic features that are clearly described in the text and augmented with color photographs and greyscale line drawings. The histologic images are from mostly hematoxylin and eosin stained microscopic slides showing various organ systems at high and low magnification. In addition, each chapter provides helpful tips for invertebrate dissection and information on how to process invertebrates for histology. This important book: Presents detailed information on histology of all major groups of invertebrates Offers a user-friendly text that is organized by taxonomic group for easy reference Features high-quality color photographs and drawings, with slides showing histology and gross photographs to demonstrate anatomy Provides details on invertebrate dissection and processing invertebrates for histology Written for veterinary pathologists, biologists, zoologists, students, and other scientists studying these species, Invertebrate Histology offers the most updated information on the topic written by over 20 experts in the field.

Phylogeny and Evolution of the Mollusca


Book Description

"Ponder and Lindberg provides a breathtaking overview of the evolutionary history of the Mollusca, effectively melding information from anatomy, ecology, genomics, and paleobiology to explore the depths of molluscan phylogeny. Its outstanding success is due to thoughtful planning, focused complementary contributions from 36 expert authors, and careful editing. This volume is a must for malacologists."—Bruce Runnegar, Department of Earth and Space Sciences, University of California, Los Angeles "Our understanding of the phylogeny and evolutionary history of the mollusca has been revolutionized over the past two decades through new molecular data and analysis, and reinvestigation of morphological characters. In this volume Ponder, Lindberg, and their colleagues do a wonderful job of integrating this work to provide new perspectives on the relationships of the major molluscan clades, their evolutionary dynamics, and their history. Particularly timely is the coverage of molluscan evo-devo and genomics."—Douglas H. Erwin, Curator of Paleozoic Invertebrates, National Museum of Natural History




Molluscs


Book Description

This book is divided into four sections. The first section "Introduction" offers information on mollusc generalities. In addition, these organisms are important in areas of commercial significance such as aquaculture and fishing. Similarly, it was pointed out in the use of molluscs have uses in pollution studies and environmental processes among others. The second section "Social Aspects of Fisheries" considers aspects of molluscs gathering in tropical regions. The third section "Ecology" presents the results of long-term research concerning the study of variability of the size/mass relationships in the mollusc Rapana venosa from the northwestern part of the Black Sea and near the eastern coast of Crimea (Sudak Gulf). The fourth section "Immune System" sheds light on the elements of the molluscan immune system and survival differences against Vibrio vulnificus and Vibrio parahaemolyticus. This book can be consulted by students, professors, and researchers in biological sciences and related areas.




Reproduction and Development in Mollusca


Book Description

This book is perhaps the first attempt to comprehensively project the uniqueness of molluscs, covering almost all aspects of reproduction and development from aplacophorans to vampyromorphic cephalopods. Molluscs are unique for the presence of protective external shell, defensive inking, geographic distribution from the depth of 9,050 m to an altitude of 4,300 m, gamete diversity, the use of nurse eggs and embryos to accelerate the first few mitotic divisions in embryos, the natural occurrence of androgenics in a couple of bivalves, viable induced tetraploids, gigantism induced by elevated ploidy, the complementary role played by mitochondrial genome in sex determination by nuclear genes and the uptake and accumulation of steroid hormone from surrounding waters. In molluscs, sexuality comprises of gonochorism ( 24%), protandry (




The Biology of Terrestrial Molluscs


Book Description

Gastropods on land: phylogeny, diversity and adaptive morphology; Body wall: form and function; Sensory organs and the nervous system; Radular structure and function; Structure and function of the digestive system in Stylommatophora; Food and feeding behaviour; Haemolymph: blood cell morphology and function; Structure and functioning of the reproductive system; Regulation of growth and reproduction; Spermatogenesis and oogenesis; Population and conservation genetics; Life history strategies; Behavioural ecology: on doing the right thing, in the right place at the right time; Soil biology and ecotoxicology.




Physiology of Mollusca


Book Description

Physiology of Mollusca, Volume II focuses on the physiology of mollusks, as well as feeding, digestion, mechanics of the heart, metabolism, and pigmentation. The selection first offers information on feeding and digestion, including Amphineura, Gastropoda, Bivalvia, anatomy of the gut, movement of food, and digestive diverticula. The text then elaborates on feeding and digestion in cephalopods and heart, circulation, and blood cells. Discussions focus on food and feeding, mechanics of heart and circulation, control of the heart, cardioregulatory substances, and blood cells. The publication considers respiration, molluscan hemoglobin and myoglobin, and molluscan hemocyanins. The text then examines the pigmentation of mollusks, carbohydrate and nitrogen metabolism, physiology of the nervous system, and sense organs. Topics include indole pigments, sugar and polysaccharides, metabolism of nitrogenous compounds, terminal products of nitrogen metabolism in mollusks, and synaptic transmission. The selection is a dependable reference for readers interested in the physiology of mollusks.
