Animal behaviors are among the most diverse and complex products of evolution. They represent a major source of variation both within and between populations. As with all aspects of evolution, there are boundaries that determine the freedom of behavioral characteristics to vary. To understand the causes and consequences of such variation, it is essential to define these boundaries. Defining them, in turn, requires that we understand the biological substrates of behavior and how they are subject to variation. In this unique volume, 58 international experts attempt to analyze and discuss the elements of behavior at many different levels and from many different disciplines. By focusing on the flexible and constrained aspects of behavior, they have been able to look for common themes in the biological strategies for organizing and producing behavior that exist at molecular, physiological, and evolutionary levels. They discuss the role of development and circuit modulation, as well as the versatile roles of individual genes and individual cells in them. Throughout, they have taken an integrative look at a subject that demands this kind of approach. This volume should be of interest to behaviorists, neuroscientists, behavioral ecologists, and psychologists. Goal of this Dahlem Workshop: to examine the factors contributing to flexibility and constraint in behavior (molecular, genetic, physiological, evolutionary) and to explore their contribution to a deeper understanding of the interplay between behavior and evolution.

In this volume, 25 scientists from around the world review the most recent advances in the study of how frogs and toads communicate. The contributors - who are experts in disciplines including animal behaviour, developmental biology, endocrinology, evolution, ecology and neurobiology - examine this amphibian order's vocal, visual and chemical signals, the physiology and energetics of their production, neural processing, related behaviours, and evolutionary implications. As the chapters demonstrate, research developments have led to further understanding of the role of the anuran larynx in sound production, how the anuran brain recognizes sound, and how both of these processes are influenced by the animal's physiological state. The contributors also discuss male-to-male call strategies as well as how female preferences for call variation contribute to sexual selection, speciation and hybridization. The text presents material about kin recognition abilities and the surprising range of visual displays by tropical anurans, and examines how the inherent structure of the auditory system might generate sensory biases that influence signal evolution.

This book is an essential guide to nonlinear dynamics and vibration control, detailing both the theory and the practical industrial applications within all aspects of engineering. Demonstrating how to improve efficiency through reducing unwanted vibration, it will aid both students and engineers in practically and safely improving flexible structures through control methods. Increasing demand for light-weight robotic systems and space applications has actuated the design and construction of more flexible structures. These flexible structures, involving numerous dynamic systems, experience unwanted vibrations, impacting accuracy, operating speed, safety and, importantly, efficiency. This book aids engineers in assuaging this issue through vibration control methods, including nonlinear dynamics. It covers topics such as dynamic modeling of nonlinear system, nonlinear oscillators, and modal analyses of multiple-mode system. It also looks at vibration control methods including linear control, nonlinear control, intelligent control, and command smoothers. These control methods are effective and reliable methods to counteract unwanted vibrations. The book is practically minded, using industrial applications throughout, such as bridge cranes, tower cranes, aerial cranes and liquid sloshing. It also discusses cable-suspension structures, light-weight links, and fluid motions which exhibit flexible-structure dynamics. The book will be of interest to students and engineers alike, in the field of mechatronics, mechanical systems and signal processing, nonlinear dynamics, vibration, and control engineering.

Constraints and Databases contains seven contributions on the rapidly evolving research area of constraints and databases. This collection of original research articles has been compiled as a tribute to Paris C. Kanellakis, one of the pioneers in the field. Constraints have long been used for maintaining the integrity of databases. More recently, constraint databases have emerged where databases store and manipulate data in the form of constraints. The generality of constraint databases makes them highly attractive for many applications. Constraints provide a uniform mechanism for describing heterogenous data, and advanced constraint solving methods can be used for efficient manipulation of constraint data. The articles included in this book cover the range of topics involving constraints and databases; join algorithms, evaluation methods, applications (e.g. data mining) and implementations of constraint databases, as well as more traditional topics such as integrity constraint maintenance. Constraints and Databases is an edited volume of original research comprising invited contributions by leading researchers.
