Ecological Physiology of Daily Torpor and Hibernation (Fascinating Life Sciences)

by Fritz Geiser

This book provides an in-depth overview on the functional ecology of daily torpor and hibernation in endothermic mammals and birds. The reader is well introduced to the physiology and thermal energetics of endothermy and underlying different types of torpor. Furthermore, evolution of endothermy as well as reproduction and survival strategies of heterothermic animals in a changing environment are discussed.Endothermic mammals and birds can use internal heat production fueled by ingested food to maintain a high body temperature. As food in the wild is not always available, many birds and mammals periodically abandon energetically costly homeothermic thermoregulation and enter an energy-conserving state of torpor, which is the topic of this book. Daily torpor and hibernation (multiday torpor) in these heterothermic endotherms are the most effective means for energy conservation available to endotherms and are characterized by pronounced temporal and controlled reductions in body temperature, energy expenditure, water loss, and other physiological functions. Hibernators express multiday torpor predominately throughout winter, which substantially enhances winter survival. In contrast, daily heterotherms use daily torpor lasting for several hours usually during the rest phase, some throughout the year. Although torpor is still widely considered to be a specific adaptation of a few cold-climate species, it is used by many animals from all climate zones, including the tropics, and is highly diverse with about 25-50% of all mammals, but fewer birds, estimated to use it. While energy conservation during adverse conditions is an important function of torpor, it is also employed to permit or facilitate energy-demanding processes such as reproduction and growth, especially when food supply is limited. Even migrating birds enter torpor to conserve energy for the next stage of migration, whereas bats may use it to deal with heat. Even though many heterothermic species will be challenged by anthropogenic influences such as habitat destruction, introduced species, novel pathogens and specifically global warming, not all are likely to be affected in the same way. In fact it appears that opportunistic heterotherms because of their highly flexible energy requirements, ability to limit foraging and reduce the risk of predation, and often pronounced longevity, may be better equipped to deal with anthropogenic challenges than homeotherms. In contrast strongly seasonal hibernators, especially those restricted to mountain tops, and those that have to deal with new diseases that are difficult to combat at low body temperatures, are likely to be adversely affected. This book addresses researchers and advanced students in Zoology, Ecology and Veterinary Sciences.

Placentation in Mammals: Tribute to E.C. Amoroso’s Lifetime Contributions to Viviparity (Advances in Anatomy, Embryology and Cell Biology #234)

by Rodney D. Geisert Thomas E. Spencer

The present volume of the book series Advances in Anatomy, Embryology and Cell Biology brings together current reviews from leading experts to address the diversity of placentation by which species establish and maintain pregnancy. Development of viviparity and placentation in rodents, dogs, pigs, cattle, horses, marsupials, primates and elephants are discussed. The development of viviparity in mammals, including some invertebrate species, required the adaptation of the placenta to serve as a functional conduit for interplay between the semiallograftic fetus with the maternal uterus. Although the ‘placenta’ protects the fetus from maternal immune rejection and provides oxygen and nutrient flow to support it to term across all the species, structural differentiation of this fetal-maternal interface can vary from simple to very complex. E.C. Amoroso contributed greatly to our early understanding and knowledge of placentation across a great variety of species. His work on placentation provides numerous illustrations and histological sections which are used for teaching and stimulating research today. With this book, we want to pay tribute to his lifetime contributions to the field by reviewing our current understanding of the development of viviparity and placentation in different species. The book is written for researchers, physicians and medical students working in the field of reproductive science or with an interest in placentation and viviparity.

Michael Foster and the Cambridge School of Physiology: The Scientific Enterprise in Late Victorian Society

by Gerald L. Geison

Despite great ferment and activity among historians of science in recent years, the history of physiology after 1850 has received little attention. Gerald Geison makes an important contribution to our knowledge of this neglected area by investigating the achievements of English physiologists at the Cambridge School from 1870 to 1900. He describes individual scientists, their research, the scientific issues affecting their work, and socio-institutional influences on the group. He pays special attention to the personality and contributions of Michael Foster, founding father of the Cambridge School. Foster's specific research interest was the origin of the rhythmic heartbeat, and the author contends that the school itself descended from and developed around this concern.Originally published in 1978.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Waders of Europe

by Lars Gejl

Waders are spectacular members of our avifauna. They are especially prevalent along coasts and in wetlands during the spring and autumn migration periods, when members of several species may perform dramatic flocks that wheel and turn in flight. While waders are often particularly striking in summer plumage, identifying these birds outside the breeding season can be problematic for even the most confident of birdwatchers.Waders of Europe is the ultimate guide to wader identification, ecology and biology. Through outstanding photography and concise, detailed text, this book is indispensable for anyone interested in learning more about waders, and is an invaluable tool for identifying birds to species level in the field.

The Practitioner’s Guide to Psychoactive Drugs

by Alan J. Gelenberg Ellen L. Bassuk Stephen C. Schoonover

In the eight years since the publication of the second edition of this Guide, psycho­ phannacotherapy has made many advances not only through the discovery of new medications but by the effective directing of their use to an ever-increasing variety of clinical disorders. These welcome developments are reflected in the concurrent growth and development of the Guide itself, which now enters adulthood with renewed vigor. Under the thoughtful and scholarly leadership of Dr. Alan Gelenberg, the third edition has undergone a significant transformation designed to meet the needs of the modem clinician. The panel of contributors is nearly double that of the former edition with the addition of nine new authors, who have helped in the major revision and rewriting of the text and in a broadening of the topics included. As a conse­ quence, the reader is assured of a thorough and thoroughly up-to-date coverage of current psychopharmacology that is both accurate and aimed at clinical utility. Having reached maturity, the third edition, while maintaining the lineaments of its earlier versions, is a considerably expanded and strengthened guide to treatment. Although now more encyclopedic in content, the new Practitioner' s Guide to Psy­ choactive Drugs retains the virtues of a clinical vade mecum that informed its predecessors and have eamed it a place by the patient's bedside for weIl over a decade. One may confidently anticipate its long and flourishing career in the years ahead. John C. Nemiah, M.D.
