Download or read book Salt Glands in Birds and Reptiles written by M. Peaker and published by Cambridge University Press. This book was released on 1975-07-03 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the authors in writing this monograph has been to provide a comprehensive and critical, but personal account of salt glands. Papers on salt glands are scattered through a great many different journals. There is therefore a great need for a synthesis of what is known about salt glands. The means by which salt glands perform their vital function of forming and excreting a concentrated salt solution is of great biological importance in understanding salt and water relations in the cells of all living things. In addition to the basic physiology of salt glands there is consideration of their ecological importance, their interaction with other systems of the body, their role in non-marine birds and reptiles and their evolution. Salt glands have interested biologists from a wide range of disciplines. This book brings together the scattered literature and will be a convenient source of reference to those working in the field, as well as providing information for comparative studies and for teaching purposes.
Download or read book The Physiological Ecology of Vertebrates written by Brian Keith McNab and published by Cornell University Press. This book was released on 2002 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though physiological ecology has been a discipline since the 1950s, McNab redresses a perceived absence of a theoretical framework with a comparative, inductive approach to studying vertebrate evolution and ecology. He discusses the patterns and limits of adaptation to the environment, acclimation to temperature variation and material exchange with the environment, and the energetics of locomotion and growth. The final section treats the significance of energetics for population ecology and distribution. Includes a taxonomic as well as subject index. Suitable for advanced students and researchers in the biological and ecological sciences. The Gainesville, FL-based author is referred to by the foreword writer as a keen naturalist, but his credentials are not stated. Annotation copyrighted by Book News Inc., Portland, OR.
Download or read book NaCl Transport in Epithelia written by R. Greger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the pioneering studies by Ussing and co-workers, studies of epithelial Nael transport have come a long way. The first phase of the phenomenological description of the cell as a black box has been follow ed by studies of cellular mechanisms, the interplay of the different trans port components, and the mechanisms of regulation. A broad spectrum of methods has been applied to many epithelia in a variety of species. For the individual epithelia transport schemes have been proposed, and, at this point I think it is appropriate to take a pause and search for elements common to several epithelia. This aspect triggered the publica tion of this book, and in fact the various chapters emphasize that the funetional eomponents, expressed in the various epithelia, are not in finite in number, but they occur in epithelia which are separated in evolu tion by several hundred million years. The authors come both from the field of veterinary and human physiology as weIl as from biology. In my opinion, the close contacts and eollaborations between physiologists and biologists have been essential for the progress in this field. I wish to thank all authors for their con tributions, and I hope that the reader will appreciate this collection of up to date reviews on epithelia in nonvertebrates and vertebrates.
Download or read book Osmoregulation in Birds written by E. Skadhauge and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The approach of this treatise is physiological throughout. In the eyes of the author it answers the rhetorical question raised by Maurice B. Visscher at the Physiology Congress in Washington D. C. in 1968: Does physiology exist? What he meant by this question was whether the fields of cellular physiology and physiology of the various organ systems had become so large that physiology as such had vanished. The firm answer is that physiology does indeed exist. Although it is important to study physiological problems at the subcellular level, it is importan- and equally difficult - to study organ regulation at the cellular level, organ interaction, and integration into the whole organism. An account of avian osmoregulation from an integrated point of view is attempted in this book. Since reading Homer W. Smith's From Fish to Philosopher and August Krogh's Osmoregulation in Aquatic Animals verte brate osmoregulation has been in the center of the author's interest. The focus was set on avian osmoregulation after personal contact with the School of Krogh when working in the laboratory of Bodil M. Schmidt-Nielsen. The fundamental concepts and isotope techniques introduced by Hans H. Ussing have been of constant inspiration. An excellent example for the study of osmoregulation at the cellular level was given by the late Jean Maetz. The writing of this book was suggested by Donald S. Farner who is thanked for thorough editorial assistance, and especially with help in the subtle semantic peculiarities of the English language.

Download or read book Osmoregulation in Estuarine and Marine Animals written by A. Pequeux and published by Springer. This book was released on 1984-06-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wealth of information on osmotic and ionic reaulation in Estuarine and Marine Animals has been accumulated over the past decades. Beyond early studies of whole-animal responses to changes in envi ronmental salinities, efforts have been made later on to identify, to localize and to characterize the organs and structures responsible for the control of the characteristics of the cell's environmental fluid. When considering the problem of cell volume control in animals facing media of fluctuating salinities, we are indeed dealing with two different categories of mechanisms. A first one is concerned with the control of the osmolality of the intracellular fluid, hence with the processes directly implicated in the maintenance of cell volume and shape. They have been extensively described in several recent review papers. The second category includes the processes controllin~ the charac teristics of the cell's environmental fluid in order to minimize the amplitude of the osmotic shocks the cells may have to cope with upon acclimation to media of changed salinities. They are localized in particular organs and structures : the so-called "caZt-transporting" epithelia. Up to now, most of the studies on salt-transportino epithe lia in estuarine and marine animals used the black box approach, so that little or sometimes nothing is still known on the physiological, the biochemical and the biophysical basis of the transporting mecha nisms as well as on the structure-function relationships.
Download or read book Eckert Animal Physiology written by David J. Randall and published by Macmillan. This book was released on 2002 with total page 814 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic animal physiology text focuses on comparative examples that illustrate the general principles of physiology at all levels of organisation—from molecular mechanisms to regulated physiological systems to whole organisms in their environment. This textbook is an authoritative and complete guide to the field of animal physiology which uses a threefold approach to teaching. The Comparative Approach emphasises basic mechanisms but allows patterns of physiological function in different species to demonstrate how evolution creates diversity. This approach encourages students to appreciate the underlying principles that govern physiological systems. The Experimental Emphasis helps students to understand the process of scientific discovery and shows how our knowledge of physiology continually increases and finally the Integrative Approach presents information about specific physiological systems at all levels of organisation, from molecular interactions to interactions between an organism and its environment.n included.
Download or read book Homeostasis in Desert Reptiles written by Sidney Donald Bradshaw and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deserts, whether hot or cold, are considered to be one of the most difficult environments for living systems, lacking the essential free water which ac counts for approximately 60-70% of their body mass and more than 98% of their constituent atoms {Macfarlane 1978}. Amongst vertebrates, reptiles are usually thought of as the animals most adapted or suited to such environments because of their diurnal habit, based on a need for external heat, and their ability to survive far from obvious sources of water. This impression is rein forced when one examines the composition of vertebrate faunae characteristic of deserts and arid zones: reptiles predominate and they are often the only vertebrates to be found in hyper-arid areas, such as some parts of the Sahara {Monod 1973}. I recently had occasion to examine this assumption carefully, however, and was led inexorably to the conclusion that reptiles represent a particularly successful desert group, not because of their evolution of superior adaptations, but because of their possession of a basic suite of behavioural and physiologi cal characteristics that suit them uniquely to this very resource-limited environment {Bradshaw 1986a}. These fundamental reptilian characteristics are: 1. their low rates of metabolism, compared with birds and mammals, which result in extremely low rates of resource utilisation and lead to considerable economy in the handling of water 2.
Download or read book General Comparative and Clinical Endocrinology of the Adrenal Cortex written by I. Chester Jones and published by Academic Press. This book was released on 2013-10-22 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: General, Comparative and Clinical Endocrinology of the Adrenal Cortex, Volume 2 focuses on the many facets of adrenocortical form and function. This book discusses the mammalian adrenal cortex in structural, pathological, clinical, biochemical and histophysiological standpoints, including the functional and structural characteristics of the adrenocortical homologue of two poikilothermic groups- Reptilia and Amphibia. The general perspective that the adrenocortical homologue secretes materials that have an ubiquity of metabolism and mode of action in the Vertebrata is also elaborated. General, Comparative and Clinical Endocrinology of the Adrenal Cortex, Volume 2 covers the steroidogenesis in the zones of the mammalian adrenal cortex; adrenal gland in Reptilia; adrenal cortex of Amphibia; and aldosterone secretion and its clinical disorders. This volume is a good source for zoologists, biologists, and specialists interested in the endocrinology of the adrenal cortex.
Download or read book Biological Materials of Marine Origin written by Hermann Ehrlich and published by Springer. This book was released on 2014-12-01 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second monograph by the author on biological materials of marine origin. The initial book is dedicated to the biological materials of marine invertebrates. This work is a source of modern knowledge on biomineralization, biomimetics and materials science with respect to marine vertebrates. For the first time in scientific literature the author gives the most coherent analysis of the nature, origin and evolution of biocomposites and biopolymers isolated from and observed in the broad variety of marine vertebrate organisms (fish, reptilian, birds and mammals) and within their unique hierarchically organized structural formations. There is a wealth of new and newly synthesized information, including dozens of previously unpublished images of unique marine creatures including extinct, extant and living taxa and their biocomposite-based structures from nano- to micro – and macroscale. This monograph reviews the most relevant advances in the marine biological materials research field, pointing out several approaches being introduced and explored by distinct modern laboratories.
