Book Description
In an age when advanced molecular and genetic tools allow studies in various systems, amphibian metamorphosis still offers perhaps the most accessible model for the study of postembryonic organogenesis and mechanisms of hormonal regulation during vertebrate development. Amphibian Metamorphosis: From Morphology to Molecular Biology integrates findings from the most recent research with earlier observations, providing molecular and mechanistic insights into the signal transduction pathways underlying tissue-specific transformations during metamorphosis. The author, renowned expert of anuran metamorphosis and Head of the Unit of Molecular Morphogenesis at NICHD/NIH, begins with an overview of metamorphosis in different classes of amphibians and various factors that influence this process. A review of earlier morphological, cellular, and biochemical changes focuses on organs and tissues that have been studied extensively at the molecular level, while discussion of the thyroid hormone signal transduction pathway emphasizes transcriptional regulation mechanisms by thyroid receptors. The book provides a summary and comparison of gene regulation programs induced by thyroid hormone in several organs that undergo distinct metamorphic transformations. Several chapters are devoted to functional and mechanistic implications of the molecular findings on the thyroid hormone response genes in tissue transformation. Special features of this book include: * An emphasis on integrating the morphological approach with molecularand cell biology * A historical perspective on the progression from discovery of the thyroid hormone to present-day research advances * Comparisons of amphibian and insect metamorphosis * Dozens of instructive photographs, several in full color Amphibian Metamorphosis: From Morphology to Molecular Biology is a unique and invaluable resource for professionals and aspiring professionals in develop-mental biology, molecular biology, cell biology, evolutionary biology, and endocrinology.

Book Description
Physiology of the Amphibia, Volume III consists of 10 chapters beginning with a discussion on amphibian color changes and the various aspects of the molting cycle. Possessing a skin more suitable for life in the water, the amphibians need to prevent excessive water loss from their body to the environment; hence, an additional mechanism for reducing the hazards of desiccation in many anuran species is described. This book also tackles the physiology of amphibian cells in culture. Furthermore, the animals' nervous, visual, and auditory systems; their immunity; and metamorphosis are explained in this text. This reference will be useful to general biologists and to students with interests in animal physiology.

Book Description
Physiology of the Amphibia, Volume II focuses on the various aspects of amphibian reproduction, both physiological and behavioral, and the interrelationship between these mechanisms and the environment. Organized into five chapters, the book begins with the integrative functions of the amphibian brain. It then describes the cytophysiology of the amphibian adenohypophysis, as well as their reproductive organs and associated sexual structures. It also discusses the physiology of the process of yolk formation, vitellogenesis. The reproductive and courtship patterns and intersexuality among amphibians are also described. This book will be useful to general biologists as a reference source and to students with interests in animal physiology.

Book Description
The Color Atlas of "Xenopus laevis" Histology provides the first central source on the microscopic anatomy of cells, tissues, and major organs of the adult South African clawed frog, Xenopus laevis. For many years, X. laevis has been a highly popular experimental animal model in many areas of research. The recent development of transgenic Xenopus technology offers the promise that this animal model will be utilized more than ever before. The purpose of this book is to provide the active researcher with a central source of high quality light microscopic color images of the tissues of X. laevis, to aid in the identification of the cells and tissues of interest.

Book Description
The book describes significant multidisciplinary research findings at the Università Politecnica delle Marche and the expected future advances. It addresses some of the most dramatic challenges posed by today’s fast-growing, global society and the changes it has caused, while also discussing solutions to improve the wellbeing of human beings. The book covers the main research achievements made in the social sciences and humanities, and includes chapters that focus on understanding mechanisms that are relevant to all aspects of economic and social interactions among individuals. In line with Giorgio Fuà’s contribution, the interdisciplinary research being pursued at the Faculty of Economics of Università Politecnica delle Marche is aimed at interpreting the process of economic development in all of its facets, both at the national and local level, with a particular focus on profit and non-profit organizations. Various disciplines are covered, from economics to sociology, history, statistics, mathematics, law, accounting, finance and management.

Book Description
The book provides the most comprehensive review of lamprey biology since Hardisty and Potter’s five-volume “The Biology of Lampreys” published more than 30 years ago. Published in two volumes, it includes contributions from international lamprey experts, reviewing and providing new insights into the evolution, general biology, and management of lampreys worldwide. This first volume offers up-to-date chapters on the systematics, general biology, conservation status, and conservation needs of lampreys. It will serve as an important reference for researchers working on any aspect of lamprey biology and fishery managers whose mandate is to control or conserve lamprey populations.
