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.

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

Download or read book Monitoring Wilderness Stream Ecosystems written by and published by . This book was released on 2001 with total page 148 pages. Available in PDF, EPUB and Kindle. 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 Behavior and Its Neural Control in Gastropod Molluscs written by Ronald Chase and published by Oxford University Press. This book was released on 2002-07-18 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past quarter century, there has been a tremendous expansion in our knowledge about gastropods, their behavior and their neurobiology. We can understand a great deal about mammalian nervous systems by studying the relatively larger and simpler structure of the gastropod nervous system. Behavior and Its Neural Control in Gastropod Molluscs first reviews the broader aspects of molluscan biology and draws attention to the special features of the gastropod nervous system. The book then examines different types of behavior, reviewing progress in understanding the mechanisms of neural control, and emphasizing cases in which control can be attributed to identified neurons and identified neural circuits.
