Available in PDF, EPUB and Kindle. Book excerpt: For 50 million years Florida was home to hordes of strange and wonderful animals. Their remains accumulated in rivers, springs, and oceans. Today fossilized bones and teeth wash up along streams, banks, and beaches and lie in limerock quarries. This guide teaches how and where to hunt fossils—with maps, means of identification, and the history of these fossil treasures. Complete, accurate, and fully illustrated, including an outstanding identification section.

Download or read book Physiology of Mollusca written by Karl M. Wilbur and published by Academic Press. This book was released on 2013-10-22 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Biology of the Mollusca written by R. D. Purchon and published by Elsevier. This book was released on 2013-10-22 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reviews the most important literature on the functional morphology and natural history of molluscs over a period of half a century, from 1925 to the present day, and draws extensively upon authoritative papers published mostly in the English language in a large number of international journals during this period. By these means it is hoped to provide an anthology of what is most interesting in the literature in a number of selected topics. Appendices give some practical assistance for the dissection of selected examples

Book excerpt: A protocol and methods for monitoring the major physical, chemical, and biological components of stream ecosystems are presented. The monitoring protocol is organized into four stages. At stage 1 information is obtained on a basic set of parameters that describe stream ecosystems. Each following stage builds upon stage 1 by increasing the number of parameters and the detail and frequency of the measurements. Stage 4 supplements analyses of stream biotic structure with measurements of stream function: carbon and nutrient processes. Standard methods are presented that were selected or modified through extensive field application for use in remote settings.

Download or read book Phylogeny and Evolution of the Mollusca written by Winston Ponder and published by Univ of California Press. This book was released on 2008-03-25 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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
