This book discusses biochemical adaptation to environments from freezing polar oceans to boiling hot springs, and under hydrostatic pressures up to 1,000 times that at sea level. Originally published in 1984. 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.

Comparative developmental physiology is a growing discipline examining a diversity of organisms as they transform from single cells to mature, reproductive individuals. This collection of original, innovative essays emerged from a Roundtable on Comparative Developmental Physiology held in Glen Rose, Texas in the summer of 2002. This meeting brought together investigators studying the physiology of developing animals in an effort to identify the field's potential contributions to biology. The participants honed in on common emerging themes and future goals, which are reflected in the chapters within. The nascent community of comparative developmental physiologists was challenged to amplify the power of data collection and tool development by focusing on a few select model organisms, while still employing the power of the broader, more traditional comparative approach. Evolution has provided comparative developmental physiologists with remarkable biological diversity, which they have used to investigate a broad range of questions critical for understanding how life works. This goes beyond the basic nuts and bolts of cellular mechanisms to the functional whole, from the mechanistic level to behavior within and between organisms. The union of developmental biology with the breadth of comparative physiology holds much promise for a deeper understanding of evolutionary processes.

Afrika war die Wiege der Vor- und Urmenschen; es gibt keinen einzigen Fossilienfund aus irgendeinem Teil der Welt, der dies widerlegen könnte. Daher steht dieser Kontinent im Zentrum der Wissenschaft von den fossilen Menschen, der Paläoanthropologie. Ihre Fachvertreter versuchen, unter häufig schwierigsten Arbeitsbedingungen, die Stammesgeschichte des Menschen zu rekonstruieren. Sie brauchen eine fundierte wissenschaftliche Ausbildung, eine schier unendliche Geduld, um die Reste unserer Vorfahren aufzuspüren und zu bergen, modernste Technik, um sie zu untersuchen, und ein gut ausgebildetes Kombinationsvermögen, um das Puzzle zusammenzusetzen, aus dem sich ein zusammenhängendes Bild unserer eigenen Urgeschichte ergeben soll. Wo und wie Paläoanthropologen arbeiten, welche Erkenntnisse sie bislang gewonnen haben und welche neuen Fragen sich aus den Resultaten ihrer Forschung für den modernen Menschen ergeben, wird in dem vorliegenden Band verständlich und spannend geschildert.

One of the first textbooks in this emerging important field of ecology. Most of ecology is about metabolism: the ways that organisms use energy and materials. The energy requirements of individuals – their metabolic rates – vary predictably with their body size and temperature. Ecological interactions are exchanges of energy and materials between organisms and their environments. So metabolic rate affects ecological processes at all levels: individuals, populations, communities and ecosystems. Each chapter focuses on a different process, level of organization, or kind of organism. It lays a conceptual foundation and presents empirical examples. Together, the chapters provide an integrated framework that holds the promise for a unified theory of ecology. The book is intended to be accessible to upper-level undergraduate, and graduate students, but also of interest to senior scientists. Its easy-to-read chapters and clear illustrations can be used in lecture and seminar courses. Together they make for an authoritative treatment that will inspire future generations to study metabolic ecology.

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.

This volume collects selected papers from the 3rd ICCPB in Africa: Animals and Environments. A wide and integrated discussion of how animals persist in their normal habitats aims to improve our appreciation of animal interaction with, and response to, environment. In a time of persistent reductionism in biological studies, the collected papers discuss both breadth and depth of adaptive animal biology from more holistic perspectives. The discussion ranges from unicellular organisms to whole animals. Themes include; molecular bases of physiological response to hypoxia and the role of hypoxia inducible factors; adaptive mechanisms of ion homeostasis in crustaceans, signaling and respiration in insects; aspects of metal contamination; extremes of temperature and water availability; foraging, predation, and the acquisition of food; in the light of specific environmental demands. This volume will be of specific interest researchers in the field of adaptive molecular and evolutionary physiology and biochemistry. Biologists interested in how animals respond to their environment - be it with a molecular, physiological or ecological emphasis will find the breath of issues both stimulating and informative. "Animals and Environments" collates works in Comparative and Evolutionary Physiology and Biochemistry - covering a range of subject material and approaches seldom brought together in a single volume. Inclusion in a single volume of molecular, biochemical and physiological material aimed at addressing adaptation to environment Many of the individual works are reviews in their own right and provide an excellent resource. The diversity of approaches and material examining the evolution of adaptive mechanisms.

Organisms must cope with environmental change over time, yet organism adaptation to environmental heterogeneity over time scales is much less well-studied than adaptation to environmental heterogeneity over spatial scales. Global climate change is altering the temporal pattern of change in climate in a complex manner, including an increase in frequency of extremes and increases in mean temperature. Therefore, it is increasingly important to understand organisms' response to time scales of environmental heterogeneity to understand organism response to future climate change. This thesis presents: methods for quantifying temporal environmental heterogeneity; a theoretical framework for rigorous empirical examination of organism response to time scales of environmental heterogeneity; and empirical studies of the ability of extant adaptations of Lepidoptera to ameliorate the influence on individual fitness of time scales of heterogeneity in the thermal environment associated with climate change.
