This volume grew out of the 2nd International Symposium on Behavioral and Morphological Asymmetries, which took place in St. Petersburg (Russia) in September 2004 at the St. Petersburg State University under the patronage of the St. Petersburg Society of Naturalists. The Symposium is the descendant of a satellite event with a similar name of the 4t
Lateralization of brain and behaviour is now considered a common feature for all vertebrates, from agnathans and fish to birds and mammals. An important place in this field of research is occupied by amphibians and reptiles - the key classes to understand evolution of lateralization of behaviour and its relations to structure and development. This special issue of Lateralitycomprises a collection of papers, presented at the International Symposium on Behavioural and Morphological Asymmetries in Amphibians and Reptiles - the first of its kind. This is the first attempt to integrate and overview the works in the young field of study of lateralization in herpetological subjects, which is only about five years old. The issue is focused on amphibians (as reptiles are less involved so far) and specifically on the relations of behavioural and morphological directional asymmetries. It might serve as a starting point for future meetings and raise a number of evolutionary and developmental questions, directing the ways of prospective research. The issue consists of six review and original papers written by invited experts in the field. It provides references to almost all the available literature on the subject. Being a 'state-of-the-art' book, the issue is suitable for both advanced students and researchers specializing in behavioural sciences, neuroscience, developmental biology and morphology, who might wish to join the study of asymmetry in lower tetrapods for deeper insights into its evolution, development and function.ons, directing the ways of prospective research.

This book explores afresh the long-standing interest, and emphasis on, the `special' capacities of primates. Some of the recent discoveries of the higher cognitive abilities of other mammals and also birds challenge the concept that primates are special and even the view that the cognitive ability of apes is more advanced than that of nonprimate mammals and birds. It is therefore timely to ask whether primates are, in fact, special and to do so from a broad range of perspectives. Divided into five sections this book deals with topics about higher cognition and how it is manifested in different species, and also considers aspects of brain structure that might be associated with complex behavior.
Functional lateralization in the human brain was first identified in the classic observations by Broca in the 19th century. Only one hundred years later, however, research on this topic began anew, discovering that humans share brain lateralization not only with other mammals, but with other vertebrates and even invertebrates. Studies on lateralization have also received considerable attention in recent years due to their important evolutionary implications, becoming an important and flourishing field of investigation worldwide among ethnologists and psychologists. The chapters of this book concern the emergence and adaptive function of lateralization in several aspects of behavior for a wide range of vertebrate taxa. These studies span from how lateralization affects some aspects of fitness in fishes, or how it affects the predatory and the exploratory behavior of lizards, to navigation in the homing flights of pigeons, social learning in chicks, the influence of lateralization on the ontogeny process of chicks, and the similarity of manual lateralization (handedness) between humans and apes, our closest relatives.
This book vividly describes how complex and integrated movements can arise from the properties and behaviors of biological molecules. It provides a uniquely integrated account in which the latest findings from biophysics and molecular biology are put into the context of living cells. This second edition is updated throughout with recent advances in the field and has a completely revised and redrawn art program. The text is suitable for advanced undergraduates, graduate students, and for professionals wishing for an overview of this field.
This book is a collection of papers written by leaders in the field of lateralized brain function and behaviour in non-human animals. The papers cover the asymmetry of brain mechanisms and behaviour in a wide range of both vertebrate and invertebrate species. Each paper focuses on one of the following topics: the link between population-level lateralization and social behaviour; the processes in the avian brain that permit one brain hemisphere to take control of behaviour; lateralized attention to predators and the common pattern of lateralization in vertebrate species; visual and auditory lateralization; influences that alter the development of lateralization—specifically, the effect of temperature on the development of lateralization in sharks; and the importance of understanding lateralization when considering both the training and welfare of dogs. Collectively, these studies address questions of why different species have asymmetry of brain and behaviour, how it develops, and how this is dealt with by these different species. The papers report on the lateralization of different types of behaviour, each going beyond merely reporting the presence of asymmetry and shedding light on its function and on the mechanisms involved in its expression.
Asymmetry of the brain and behaviour (lateralization) has traditionally been considered unique to humans. However, research has shown that this phenomenon is widespread throughout the vertebrate kingdom and found even in some invertebrate species. A similar basic plan of organisation exists across vertebrates. Summarising the evidence and highlighting research from the last twenty years, the authors discuss lateralization from four perspectives - function, evolution, development and causation - covering a wide range of animals, including humans. The evolution of lateralization is traced from our earliest ancestors, through fish and reptiles to birds and mammals. The benefits of having a divided brain are discussed, as well as the influence of experience on its development. A final chapter discusses outstanding problems and areas for further investigation. Experts in this field, the authors present the latest scientific knowledge clearly and engagingly, making this a valuable tool for anyone interested in the biology and behaviour of brain asymmetries.
This book presents the latest research findings on the laterality of fish and other animals. It describes all aspects of lateral asymmetry, including ecology, morphology, behaviour, dynamics of lefty and righty morphs, genetics and evolution, through field observations, experiments and modeling. Lateral asymmetry in scale-eating cichlids gives a simple and beautiful example of negative frequency-dependent selection and resulting oscillation of lefty and righty morph frequencies. Lateral dimorphism is found not only in scale-eaters but in all orders of fish, shrimps and cuttlefish. Lateral asymmetry interacts between species through "cross-predation." Contrary to fish, lateral asymmetry in snails acts as, in most cases, positive frequency-dependent selection and provides deep insights into speciation. Especially, snakes eating righty snails facilitate speciation of lefty snails. As a collaboration work of field ecologists and theoretical biologists, this book covers a variety of topics on lateral asymmetry, which are consistently related to predation. The topics include behavioral ecology, population dynamics, physiology, evolution, genetics, development, learning and neuroscience, statistics, with the subjects of fish, shrimp, prawn, and crayfish, crab, cuttlefish, and snake and snail. Chapters cover new research results such as cuttlefish laterality dynamics, interaction between laterality of snails and snakes, evolution of laterality genetic system, and statistical analysis of laterality oscillation. Readers will appreciate the simplicity and beauty of lateral asymmetry and its profound impact on ecology and evolution.
