Animal Colour Changes and Their Neurohumours


Book Description

Originally published in 1948, this book covers the main papers published on animal colour changes between 1910 and 1943. It is a continuation of the work of van Rynberk and Fuchs, who produced important reviews of the topic in 1906 and 1914 respectively. During the period covered, the topic underwent a considerable growth in interest. This is reflected in a bibliographical list of over 1200 items at the end of the text, over twice the number given by Fuchs for the whole period up to 1914. Containing rigorous analysis and illustrations throughout, this book will be of value to anyone with an interest in chromatophores and the history of science.




Animal Hormones


Book Description

Animal Hormones: A Comparative Survey, Part I—Kinetic and Metabolic Hormones provides a comprehensive coverage of the properties of kinetic and metabolic hormones of both vertebrates and invertebrates; the title particularly covers the sources, actions, and secretion of the said hormones. The text first details the general concerns with the hormones, such as the history, chemical activators, mechanical activation, types, and identification. The next chapter covers the sources of kinetic and metabolic hormones. Chapters 3 and 4 tackle kinetic hormones, while Chapter 5 discusses metabolic hormones. The book will be of great interest to students, researchers, and practitioners of zoology and biochemistry.







The Control of Chromatophores


Book Description

The Control of Chromatophores focuses on the color changes in animals, particularly among the invertebrates. Cells containing pigment that can disperse or concentrate, thereby changing the tint of the organism in which they lie, are known as chromatophores. Well-developed, functional chromatophore systems are common among cephalopods, crustaceans, and poikilotherm vertebrates. Rare instances are found among other groups such as annelids, echinoderms, and insects. After an introduction to the types, chemistry, and functional significance of chromatophores, this text concentrates on the chromatophores of crustaceans, insects, cephalopods, echinoderms, and vertebrates. This book is recommended for students and biologists conducting work on chromatophores and color changes.




The Physiology of Fishes


Book Description

The Physiology of Fishes, Volume II: Behavior focuses on the physiology of fishes, as well as nervous and visual systems, sense organs, fish behavior, and pigment of fishes. The book first offers information on the nervous system, including the telencephalon, mesencephalon, metencephalon, medulla oblongata and spinal cord, autonomic nervous system, and functional development of the nervous system. The manuscript then elaborates on the sense organs, acoustico-lateralis system, and olfactory and gustatory senses of fishes. Discussions focus on component parts of the visual system, photoreceptive functions, lateral line, and the labyrinth. The manuscript takes a look at the ethological analysis of fish behavior and reproductive and parental behavior. Topics include coordinating and releasing mechanisms, ecological relationships, endocrine mechanisms, and motor processes. The text also touches on electric organs, luminous organs of fishes, and pigment of fishes. The publication is a valuable reference for readers interested in the physiology of fishes.




An Introduction to the History of Chronobiology, Volume 2


Book Description

In three volumes, historian Jole Shackelford delineates the history of the study of biological rhythms—now widely known as chronobiology—from antiquity into the twentieth century. Perhaps the most well-known biological rhythm is the circadian rhythm, tied to the cycles of day and night and often referred to as the “body clock.” But there are many other biological rhythms, and although scientists and the natural philosophers who preceded them have long known about them, only in the past thirty years have a handful of pioneering scientists begun to study such rhythms in plants and animals seriously. Tracing the intellectual and institutional development of biological rhythm studies, Shackelford offers a meaningful, evidence-based account of a field that today holds great promise for applications in agriculture, health care, and public health. Volume 1 follows early biological observations and research, chiefly on plants; volume 2 turns to animal and human rhythms and the disciplinary contexts for chronobiological investigation; and volume 3 focuses primarily on twentieth-century researchers who modeled biological clocks and sought them out, including three molecular biologists whose work in determining clock mechanisms earned them a Nobel Prize in 2017.




Color Change Mechanisms of Cold-Blooded Vertebrates


Book Description

Color Change Mechanisms of Cold-Blooded Vertebrates focuses on color change in vertebrates and its relation to endocrine control. The book first tackles physiological color changes in amphibians, elasmobranchs, teleosts, and cyclostomes. Topics include description of responses, nonvisual response, criticisms of the two-hormone hypothesis as applied to amphibians and elasmobranchs, and summary of teleost color change mechanisms. The publication then elaborates on physiological color changes in reptiles and biological assay of melanin-dispersing hormones, as well as generalities about reptilian color change, general statement on biological assay, and theoretical considerations. The manuscript ponders on the chemistry of melanin-dispersing hormones, mechanism of the melanophore, and actions of melanin-dispersing hormones on functions other than color change. Discussions focus on glandular origin of melanin-dispersing hormones, energy sources for melanin movement, and metabolism. The text is highly recommended for readers interested in color change in vertebrates.




Autonomic Nerve Function in the Vertebrates


Book Description

The intention of this book is to offer a comprehensive description and discussion of autonomic nerve function in the vertebrates from several points of view. Sections on anatomy, biochemistry of the transmitter substances and the structure, physiology and pharmacology of the different types of autonomic neurons have been included, together with chapters dealing with the autonomic nervous control of some organs and organ systems in the different vertebrate groups. Although knowledge in several of these areas is based primarily on studies of mammals, a certain emphasis has been placed on the autonomic nerve functions in the non-mammalian vertebrates to describe, from a comparative physiological point of view, the adaptations and possible "phylogenetic trends" in the development of the autonomic nerve functions in the vertebrates. It is very obvious that the literature created by the vigorous research activities within the fields of autonomic nervous anatomy, histochemistry, biochemistry, pharmacology and physiology is vast indeed, and not all aspects of the subject may have received fair treatment in the present volume. With an analogy from astronomy, it is hoped that the mass compressed into this book has reached the level of an energy-emitting neutron star, rather than the black hole which would be the result of compressing too large a mass.




The Hormones V2


Book Description

The Hormones: Physiology, Chemistry and Applications, Volume II covers the chemistry, physiology, and clinical applications of the mammalian endocrinology. This volume contains 10 chapters, and begins with discussions on the physiology and the role of ovarian hormones and androgens on vital processes. The subsequent chapters explore the biochemistry, physiology, and metabolism of specific secreted hormones, such as adrenal cortex, thyroid, and posterior pituitary hormones, and gonadotrophins. Other chapters deal also with the chemical control of nervous activity of acetylcholine, adrenaline, sympathin, and neurohormones. The concluding chapter focuses on the clinical applications of the covered hormones and their role in mammalian growth. This book is an invaluable source for mammalian endocrinologists, physiologists, biochemists, and researchers who are interested in mammalian development.




Cephalopod Cognition


Book Description

Cephalopods are generally regarded as the most intelligent group among the invertebrates. Despite their popularity, relatively little is known about the range and function of their cognitive abilities. This book fills that gap, accentuating the varied and fascinating aspects of cognition across the group. Starting with the brain, learning and memory, Part I looks at early learning, memory acquisition and cognitive development in modern cephalopods. An analysis of the chambered nautilus, a living fossil, is included, providing insight into the evolution of behavioural complexity. Part II surveys environmental responses, especially within the active and learning-dependent coleoids. The ever-intriguing camouflage abilities of octopus and cuttlefish are highlighted, alongside bioluminescence, navigation and other aspects of visual and cognitive competence. Covering the range of cognitive function, this text underscores the importance of the cephalopods within the field of comparative cognition generally. It will be highly valuable for researchers, graduates and senior undergraduate students.
