Book excerpt: Automatic image analysis has become an important tool in many fields of biology, medicine, and other sciences. Since the first edition of Image Analysis: Methods and Applications, the development of both software and hardware technology has undergone quantum leaps. For example, specific mathematical filters have been developed for quality enhancement of original images and for extraction of specific features of interest. Also, more complex programs have been developed for the analysis of object forms in distinguishing cancer cells from normal tissue cells. Just as significant, three-dimensional analysis of proteins, organelles, or macroscopic objects is even more complex. In addition, recent space-based experiments have optimized techniques for the extraction of movement parameters of numerous motile objects. The second edition of Image Analysis: Methods and Applications addresses all these new developments. Moreover, two new chapters have been added. One focuses on images on the internet, and the other discusses microscope image restoration. These chapters add significantly to the existing body of information on Internet communication protocol and environment as well as to that on image file formats considerations. The materials also include a list of internet Web sites that pertain to digital images and software along with those that relate to image processing. With these considerations in mind, Image Analysis: Methods and Application, Second Edition is of incalculable value to professionals, academics, and users of all aspects of image analysis in biology and other areas of science.

Available in PDF, EPUB and Kindle. Book excerpt: Dispersal of plants and animals is one of the most fascinating subjects in ecology. It has long been recognized as an important factor affecting ecosystem dynamics. Dispersal is apparently a phenomenon of biological origin; however, because of its complexity, it cannot be studied comprehensively by biological methods alone. Deeper insights into dispersal properties and implications require interdisciplinary approaches involving biologists, ecologists and mathematicians. The purpose of this book is to provide a forum for researches with different backgrounds and expertise and to ensure further advances in the study of dispersal and spatial ecology. This book is unique in its attempt to give an overview of dispersal studies across different spatial scales, such as the scale of individual movement, the population scale and the scale of communities and ecosystems. It is written by top-level experts in the field of dispersal modeling and covers a wide range of problems ranging from the identification of Levy walks in animal movement to the implications of dispersal on an evolutionary timescale.

Book excerpt: For several decades, bacteria have served as model systems to describe the life p- cesses of growth and metabolism. In addition, it is well recognized that prokaryotes have contributed greatly to the many advances in the areas of ecology, evolution, and biotechnology. This understanding of microorganisms is based on studies of members from both theBacteria andArchaea domains. With each issue of the various scienti?c publications, new characteristics of prokaryotic cells are being reported and it is - portant to place these insights in the context of the appropriate physiological processes. Structural and Functional Relationships in Prokaryotes describes the fundamental physiological processes for members of the Archaea and Bacteria domains. The - ganization of the book re?ects the emphasis that I have used in my 30 years of teaching a course of bacterial physiology. The philosophy used in the preparation of this book is to focus on the fundamental features of prokaryotic physiology and to use these features as the basis for comparative physiology. Even though diverse phenotypes have evolved from myriad genetic possibilities, these prokaryotes display considerable functional similarity and support the premise that there is a unity of physiology in the prokaryotes. The variations observed in the chemical structures and biochemical p- cesses are important in contributing to the persistence of microbial strains in a speci?c environment.

Book excerpt: Microbial extracellular polymeric substances (EPS) are the key components for the aggregation of microorganisms in biofilms, flocs and sludge. They are composed of polysaccharides, proteins, nucleic acids, lipids and other biological macromolecules. EPS provide a highly hydrated gel matrix in which microbial cells can establish stable synergistic consortia. Cohesion and adhesion as well as morphology, structure, biological function and other properties such as mechanical stability, diffusion, sorption and optical properties of microbial aggregates are determined by the EPS matrix. Also, the protection of biofilm organisms against biocides is attributed to the EPS. Their matrix allows phase separation in biofiltration and is also important for the degradation of particulate material which is of great importance for the self purification processes in surface waters and for waste water treatment.

Book excerpt: An exploration of the evolution, function, and mechanisms of search for resources in the mind and in the world. Over a century ago, William James proposed that people search through memory much as they rummage through a house looking for lost keys. We scour our environments for territory, food, mates, and information. We search for items in visual scenes, for historical facts, and for the best deals on Internet sites; we search for new friends to add to our social networks, and for solutions to novel problems. What we find is always governed by how we search and by the structure of the environment. This book explores how we search for resources in our minds and in the world. The authors examine the evolution and adaptive functions of search; the neural underpinnings of goal-searching mechanisms across species; psychological models of search in memory, decision making, and visual scenes; and applications of search behavior in highly complex environments such as the Internet. As the range of information, social contacts, and goods continues to expand, how well we are able to search and successfully find what we seek becomes increasingly important. At the same time, search offers cross-disciplinary insights to the scientific study of human cognition and its evolution. Combining perspectives from researchers across numerous domains, this book furthers our understanding of the relationship between search and the human mind.

Bledsoe, a scientist who has contributed to such diverse fields as mathematics, systems analysis, pattern recognition, biology, artificial intelligence, and automated reasoning. The first essay provides a sketch of his life, emphasizing his scientific contributions. The diversity of the fields to which Bledsoe has contributed is reflected in the range of the other essays, which are original scientific contributions by some of his many friends and colleagues. Bledsoe is a founding father of the field of automated reasoning, and a majority of the essays are on that topic. These essays are collected together here not only to acknowledge Bledsoe's manifold and substantial scientific contributions but also to express our appreciation for the great care and energy that he has devoted to nurturing many of the scientists working in those scientific fields he has helped found.

Available in PDF, EPUB and Kindle. Book excerpt: Adaptive behaviour is of two types only. Either an animal comes equipped by heredity with the ability to identify situations in which a built-in response is appropriate or it has mechanisms allowing it to adapt its behaviour in situations in which the correct response cannot be predicted. Adaptive behaviour of the second type comes about through natural selection, which weeds out individuals that identify situations inaccurately or respond inappropriately. Adaptive behaviour of the second type comes about through the selection of behavioural variants by the environment. This book is about the second type of adaptive behaviour, of which learning is the most highly developed form. Adaptive Behaviour and Learning constitutes a provocative theoretical integration of the psychological and biological approaches to adaptive behaviour. John Staddon's ideas will have a major impact on psychologists and zoologists' conceptions of the problem of learning. Highly readable, the book will serve as a useful text for courses in learning, animal behaviour and comparative psychology.

Book excerpt: big history and the future of humanity "This remains the best single attempt to theorize big history as a discipline that can link core concepts and paradigms across all historical disciplines, from cosmology to geology, from biology to human history. With additional and updated material, the Second Edition also offers a fine introduction to the history of big history and a superb introductory survey to the big history story. Essential reading for anyone interested in a rapidly evolving new field of scholarship that links the sciences and the humanities into a modern, science-based origin story." —David Christian, Macquarie University "Notable for its theoretic approach, this new Second Edition is both an indispensable contribution to the emerging big history narrative and a powerful university textbook. Spier defines words carefully and recognizes the limits of current knowledge, aspects of his own clear thinking." —Cynthia Brown, Emerita, Dominican University of California Reflecting the latest theories in the sciences and humanities, this new edition of Big History and the Future of Humanity presents an accessible and original overview of the entire sweep of history from the origins of the universe and life on Earth up to the present day. Placing the relatively brief period of human history within a much broader framework – one that considers everything from vast galaxy clusters to the tiniest sub-atomic particles – big history is an innovative theoretical approach that opens up entirely new multidisciplinary research agendas. Noted historian Fred Spier reveals how a thorough examination of patterns of complexity can offer richer insights into what the future may have in store for humanity. The second edition includes new learning features, such as highlighted scientific concepts, an illustrative timeline and comprehensive glossary. By exploring the cumulative history from the Big Bang to the modern day, Big History and the Future of Humanity, Second Edition, sheds important historical light on where we have been – and offers a tantalizing glimpse of what lies ahead.

Book excerpt: THIS BOOK collects together papers given at a NATO Advanced Research Workshop held at Il Ciocco (Lucca), Italy, from the 9th to the 15th April, 1989. It sets out to present the current state of understanding of the principles governing the way fluxes and concentrations are maintained and controlled in metabolic systems. Although this is a topic that has held the interest of biochemists for many years, it is only quite recently that the methods of analysing the kinetics of multi-enzyme pathways developed over the past two decades have come to be widely discussed or applied experimentally. Many biochemists remain sceptical that the new methods offer a real advance (except in complexity) over the landmark discoveries of the 1950s and 1960s relating to inhibition of enzymes at branch-points by the end products of metabolic pathways, and the interpretation of allosteric effects and cooperativity. Even those who have become convinced that the classical ideas provide only the starting point for understanding metabolic control have been by no means unanimous in their assess ment of the direction in which one should advance. In this book we have tried to include all of the current points of view, including the view that the classical theories tell us all that we need to know. We have not seen it as our role as editors to paper over the cracks that exist and to pretend that we can speak to the world with one voice.

Available in PDF, EPUB and Kindle. Book excerpt: A wounded minnow attempts to rejoin its school and the other minnows scatter in panic; a single beetle finds a pine tree to its liking and soon thousands of beetles swarm that tree and others in the vicinity; a male Syrian golden hamster is drawn along an invisible trail to a burrow where a female hamster awaits him, ready for mating. These animals are responding to received communications, but, as in countless other occurrences in nature, the language is not auditory or visual--it is chemical. Unlike humans, who gather information largely through sight and sound, most living creatures rely heavily on chemical compounds from other organisms for their basic knowledge of the world. Among the various types of these compounds are the chemical signals exchanged between members of the same species that govern social interactions crucial to survival. These signals are called pheromones (from the Greek "pherein"--to carry--and "hormon"--exciting) and they are used to send warnings, establish territorial boundaries, provoke aggression, control sexual behavior, and locate food. In this volume, organic chemist William C. Agosta explores the chemistry of pheromones and the mechanisms by which they orchestrate animal behavior. Professor Agosta details the intricate process of identifying pheromones and determining the active components within these sometimes highly complex mixtures. He also demonstrates the value of this growing body of knowledge to our understanding of evolution, ecology, human behavior, and agricultural production. The result is a fascinating look at a research area that brings together investigators, information, technologies, and procedures from the fields of biology, chemistry, and behavioral science. Chemical Communication spans the entire spectrum of life, from simple organisms, such as water molds and brown algae, to insects, birds, fish, reptiles, mammals, and in a provocative final chapter, human beings. Along the way, Dr. Agosta provides dozens of captivating examples of pheromones in action: certain male red-sided garter snakes, which increase their chances of mating successfully by "impersonating" a female, thus distracting rivals; or the bolas spiders, which capture male moths by hitting them with an adhesive ball on a string after emitting a female moth pheromone that lures the males within range. The book also includes important evidence that pheromones alter physiology as well as behavior. For example, young female mice reach maturity at an accelerated pace after constant exposure to adult male mice.
