The Mollusca, Volume 5: Physiology, Part 2 focuses on the biochemistry and physiology of mollusks. The selection first elaborates on the feeding biology of gastropods and feeding and digestion in Bivalvia and cephalopods. Discussions focus on feeding, digestion, feeding and digestive rhythms, feeding behavior, ontogeny of gastropod feeding biology, and feeding mechanisms. The text then examines the circulatory systems of gastropods and bivalves and circulation in cephalopods, including blood vessels and extracellular space, chemical control of the circulation, fluid mechanics of the circulation, and nature and anatomy of the circulatory system. The text takes a look at ionic regulation and water balance, excretion, and molluscan immunobiology. Topics include internal defenses of gastropods, bivalves, cephalopods, and Polyplacophorans, Monoplacophora, Cephalopoda, and Scaphopoda. The selection is a vital reference for researchers interested in the biochemistry and physiology of mollusks.

Animals and Environmental Fitness, Volume 1: Invited Lectures is a collection of papers that tackles ecological concerns. The materials of the book are organized according the main issue of their contents. The text first tackles the chemical factors of the environment, such as water and oxygen availability, ecomones, and pollutants. The other half of the book encompasses the physical factors of the environment that include light, pressure, and temperature. The text will be of great use to scientists who study the interaction between flora, fauna, and the total environment.

Understanding the role of aquatic biota and the impact of pollution and chemical substances that enter aquatic ecosystems is crucial to the assessment, prevention, and remediation of damaged environments. Biological Effects of Surfactants synthesizes the most important findings from hundreds of articles and the author's current experiments on the biological effects of synthetic surfactants and detergents on individual organisms, populations, communities, and ecosystems. This book offers a new perspective of the hazards of pollution. The book draws upon concepts in hydrobiology, biogeochemical cycling, and the assimilative capacity of water-beyond the self-purification capabilities of bacteria and nutrient cycling-to examine the effects of anionic, non-ionic, and cationic surfactants as well as detergent mixtures on a wide range of organisms including bacteria, cyanobacteria, flagellates, algae, higher plants, and invertebrates. The author, a distinguished member of the Russian Academy of Natural Sciences, establishes new quantitative characteristics of the effects and presents study results reflecting newly discovered phenomena. While proposing and substantiating new priorities and approaches for testing, assessing, and characterizing the biological activities and hazards of substances, he illustrates how the data obtained can be used to develop effective environmental remediation and protection measures to improve water quality. Biological Effects of Surfactants lays an excellent foundation for scientists to explore how hazardous wastes are absorbed in aquatic and terrestrial ecosystems, determine what is required for remediation and restoring water quality, and design the best approach to counteract the toxic effects of manmade surfactants using biological methods, including phytoremediation.
