Optima for Animals


Book Description

Optimization theory is designed to find the best ways of doing things. The structures of animals, their movements, their behavior, and their life histories have all been shaped by the optimizing processes of evolution or of learning by trial and error. In this revised edition of R. McNeil Alexander's widely acclaimed Optima for Animals, we see how extraordinarily diverse branches of biology are illuminated by the powerful methods of optimization theory. The mathematics involved is explained very simply, with biology students in mind, but the book is not just for them. It is also for professionals, ranging from teachers to researchers.




Optima for Animals


Book Description

Optimization theory is designed to find the best ways of doing things. The structures of animals, their movements, their behavior, and their life histories have all been shaped by the optimizing processes of evolution or of learning by trial and error. In this revised edition of R. McNeill Alexander's widely acclaimed Optima for Animals, we see how extraordinarily diverse branches of biology are illuminated by the powerful methods of optimization theory. What is the best strength for a bone? Too weak a bone will probably break but an excessively stout one will be cumbersome. At what speed should humans change from walking to running? Should a bird take only big juicy worms or should it eat every worm it finds, and do birds make the best choices? Why do the males of some species of fishes and the females of others look after the young, while the young of others are looked after by both parents or neither? Is it possible that all these policies can be optimal, in different circumstances? This book shows how these and many other questions can be answered. The mathematics involved is explained very simply, with biology students in mind, but the book is not just for them. It is also for professionals, ranging from teachers to researchers.




Principles of Animal Locomotion


Book Description

How can geckoes walk on the ceiling and basilisk lizards run over water? What are the aerodynamic effects that enable small insects to fly? What are the relative merits of squids' jet-propelled swimming and fishes' tail-powered swimming? Why do horses change gait as they increase speed? What determines our own vertical leap? Recent technical advances have greatly increased researchers' ability to answer these questions with certainty and in detail. This text provides an up-to-date overview of how animals run, walk, jump, crawl, swim, soar, hover, and fly. Excluding only the tiny creatures that use cilia, it covers all animals that power their movements with muscle--from roundworms to whales, clams to elephants, and gnats to albatrosses. The introduction sets out the general rules governing all modes of animal locomotion and considers the performance criteria--such as speed, endurance, and economy--that have shaped their selection. It introduces energetics and optimality as basic principles. The text then tackles each of the major modes by which animals move on land, in water, and through air. It explains the mechanisms involved and the physical and biological forces shaping those mechanisms, paying particular attention to energy costs. Focusing on general principles but extensively discussing a wide variety of individual cases, this is a superb synthesis of current knowledge about animal locomotion. It will be enormously useful to advanced undergraduates, graduate students, and a range of professional biologists, physicists, and engineers.




Optima and Equilibria


Book Description

Progress in the theory of economic equilibria and in game theory has proceeded hand in hand with that of the mathematical tools used in the field, namely nonlinear analysis and, in particular, convex analysis. Jean-Pierre Aubin, one of the leading specialists in nonlinear analysis and its application to economics, has written a rigorous and concise - yet still elementary and self-contained - textbook providing the mathematical tools needed to study optima and equilibria, as solutions to problems, arising in economics, management sciences, operations research, cooperative and non-cooperative games, fuzzy games etc. It begins with the foundations of optimization theory, and mathematical programming, and in particular convex and nonsmooth analysis. Nonlinear analysis is then presented, first game-theoretically, then in the framework of set valued analysis. These results are then applied to the main classes of economic equilibria. The book contains numerous exercises and problems: the latter allow the reader to venture into areas of nonlinear analysis that lie beyond the scope of the book and of most graduate courses.




Animals and Temperature


Book Description

Organisms are continually challenged to regulate and maintain functional capacities as their thermal environment changes. Adjustment to temperature change is evident both phenotypically in individual organisms and genotypically in the evolution of species. This volume addresses thermal adaptation by bringing together many of the leading researchers in thermal biology, with backgrounds spanning the disciplines of molecular biology, cell biology, physiology, zoology, ecology and evolutionary biology. The responses of many species to temperature are discussed in depth, through the molecular, cellular, organismal, population, and ecosystem levels. This text stands as an important contribution to the study of temperature adaptation.

Human Bones


Book Description

Human Bones combines an intriguing discussion of the function and design of human bones with stunningly beautiful color photographs that capture their unique elegance. R. McNeill Alexander, the world's foremost authority on biomechanics, takes the reader on a tour of the human skeleton, investigating and celebrating the human body's 213 bones. Alexander explores the nature of human bones as well as their relationship with other parts of the body in this lucid and informative book. Beginning by reminding readers that bones are living organs-they grow, suffer damage, and repair themselves just like other organs-Alexander elucidates the form and function of the myriad bones in the skull, the arms and legs, and the torso. How the bones in the arm combine with the torso at the shoulder to create a wide range of motion, and the relationship among the various parts of the skull-the nose and mouth cavities, for example-are some of the topics explored. Counterintuitive insights are revealed along the way with the help of do-it-yourself interactive experiments that prompt readers to investigate their own bodies. Why different people's bones are different is examined in detail by Alexander. This knowledge is behind important work in forensic science and archaeology: it informs the art behind the reconstruction of faces from skulls, and the composition of bones betrays information about the lives of individuals and their daily habits. Throughout the work Alexander places bones in their ancestral context, explaining the principles of evolution and how these relate to utility, and he devotes an entire chapter to exploring the evolutionary relationship between human bones and those of other mammals. Alexander's authoritative, crystalline prose, Diskin's 115 color photographs, and superb graphic design have united in this remarkable book to showcase the extraordinary beauty at the core of our bodies.

Temperature Biology of Animals


Book Description

Temperature is one facet in the mosaic of physical and biotic factors that describes the niche of an animal. Ofthe physical factors it is ecologically the most important. for it is a factor that is all-pervasive and one that. in most environments. lacks spatial or temporal constancy. Evolution has produced a wide variety of adaptive strategies and tactics to exploit or deal with this variable environmental factor. The ease with which temperature can be measured. and controlled experimentally. together with its widespread influence on the affairs of animals. has understandably led to a large. dispersed literature. In spite of this no recent book provides a comprehensive treatment of the biology of animals in relation to temperature. Our intention in writing this book was to fill that gap. We hope we have provided a modern statement with a critical synthesis of this diverse field. which will be suitable and stimulating for both advanced undergraduate and post graduate students of biology. This book is emphatically not intended as a monographical review. as thermal biology is such a diverse. developed discipline that it could not be encompassed within the confines of a book of this size.
