Our species emerged out of the depths of time into a world already populated by these great carnivores. Before we mastered iron and later developed firearms, we had few defences against bears--only watchful caution and elaborate ceremonies and sacrifices to ward off fear.Where human populations grow, bears have traditionally dwindled or disappeared. But when we return to the wild, to places where bears still survive, all our primeval fears awaken again. The risk of an automobile accident on the way to bear country far outstrips the risk of a close-range encounter with a bear, but it's the bear that worries us as we hurtle down the pavement at a hundred kilometres an hour.In this timely and sensitive book, Kevin Van Tighem calls on decades of experience, knowledge and understanding in order to enlighten readers about our relationship with and attitude toward bears. Along the way we are confronted with the realities confronting these great animals as a result of our ever-expanding human population and their ever-shrinking natural habitat. Through historical research, field observation, practical advice, personal anecdotes and an array of stunning photos, Van Tighem has written a comprehensive book that is meant to demystify bears in order to promote a deeper understanding of these powerful yet vulnerable creatures.

    As a pragmatic, hands-on guide for beginning to intermediate hobbyists, The Conscientious Marine Aquarist demystifies the process of planning, setting up, stocking, and managing a beautiful, thriving slice of the tropical ocean. A leading advocate for the responsible collection and care of wild-caught specimens, Fenner starts with the basics -- "What is a fish?" -- and proceeds to give the reader the scientific background and expert-level secrets to being a smarter consumer, better steward, and more successful marine aquarium keeper.

    More precisely, as she shows in this uniquely comprehensive and accessible survey of behavioral and evolutionary ecology, they come down to the basic principle that all organisms evolved to maximize their reproductive success and seek resources to do so.Low begins by reviewing the fundamental arguments and assumptions of behavioral ecology: selfish genes, conflicts of interest, and the tendency for sexes to reproduce through different behaviors. She explains why in primate species--from chimpanzees and apes to humans--males seek to spread their genes by devoting extraordinary efforts to finding mates, while females find it profitable to expend more effort on parenting. Low illustrates these sexual differences among humans by showing that in places as diverse as the parishes of nineteenth-century Sweden, the villages of seventeenth-century China, and the forests of twentieth-century Brazil, men have tended to seek power and resources, from cattle to money, to attract mates, while women have sought a secure environment for raising children. She makes it clear, however, they have not done so simply through individual efforts or in a vacuum, but that men and women act in complex ways that involve cooperation and coalition building and that are shaped by culture, technology, tradition, and the availability of resources. Low also considers how the evolutionary drive to acquire resources leads to environmental degradation and warfare and asks whether our behavior could be channeled in more constructive ways.

    The Eighth Edition has been thoroughly revised and updated and is available in both print and e-book formats.Janeway s Immunobiology continues to set the standard for currency and authority with its clear writing style and organization, uniform art program, and scientific accuracy. It presents a consistent point of view throughout that of the host s interaction with an environment containing many species of potentially harmful microorganisms. The full-color art program is conceptually coherent and illustrates the processes and mechanisms underlying the concepts in the text. The 16 chapters in this readable, accessible textbook are organized and presented in such a way as to help deliver a complete one-semester immunology course, beginning with innate immunity, then moving to adaptive immunity, and ending with applied clinical immunology.Discussion questions are provided at the end of Chapters 2 to 16. These questions can be used for review, or as the basis for discussion in class or in informal study groups. Summaries conclude each section and each chapter. As in previous editions, a caduceus icon in the margins indicates topics which are correlated to Case Studies in Immunology, Sixth Edition by Geha and Notarangelo.New in the Eighth EditionInnate immunity has been updated and expanded and is now presented in two separate chapters (Chapters 2 and 3), as well as being further emphasized in the rest of the textbook. Chapter 2 covers antimicrobial peptides and the complement system, and Chapter 3 deals with cellular innate receptors and cell-mediated innate immunity (e.g. TLRs, phagocytosis, NK cells, interferon production, innate-like lymphocytes). The section on complement has been reworked and reconceived explaining the lectin pathway first making it easier to teach by placing it into the context of innate recognition. Evolution is now incorporated throughout the text, helping students see similar strategies used by different organisms. The text and figures of Chapter 7 Signaling Through Immune System Receptors have been revised to present a cohesive synthesis of signaling for immunology, focusing on improved illustration of antigen recognition signaling and lymphocyte activation. Signaling through other receptors is dealt with wherever appropriate throughout the book. Updated chapter on B-cell immune responses (Chapter 10), especially on trafficking of B cells in peripheral lymphoid organs (e.g. lymph nodes) and the locations at which they encounter antigen. Coverage of mucosal immunity (Chapter 12) has been brought up to date, including responses to the commensal microbiota and the role of specialized dendritic cells and the regulatory T cells in maintaining tolerance to food antigens and commensal bacteria. Chapter 13, Failures of Host Defense Mechanisms, has been reorganized and revised to structure an understanding of primary immunodeficiencies in the context of developmental pathways. Chapter 16, Manipulation of the Immune Response, has been heavily revised to include a greater emphasis on clinical issues and a complete update of immunotherapeutics and vaccines. Many new and revised figures illustrate the processes and mechanisms underlying the concepts presented in the text. The icons used have been updated and expanded to incorporate a new emphasis on signaling pathways. New references have been added throughout the text.

    The new edition maintains the scope and expertise that made the book so popular while incorporating the latest research and updating the exquisite program of drawings.

    Jon Bailey and Mary Burch present five basic skills and strategy areas that professional behavior analysts need to acquire. This book is organized around those five areas, with a total of 25 specific skills presented within those topics. Every behavior analyst, whether seasoned or beginning, should have this book.

    But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

    That acclaimed book, as one reviewer put it, "made meteorologists the most unlikely heroes of recent literature." But, what if the warning system failed to provide a clear, timely notice of a major storm? Tragically, that scenario played out in Joplin, Missouri, on May 22, 2011. As a wedding, a high school graduation, and shopping trips were in progress, an invisible monster storm was developing west of the city. When it arrived, many were caught unaware. One hundred sixty-one perished and one thousand were injured. "When the Sirens Were Silent" is the gripping story of the Joplin tornado. It recounts that horrible day with a goal of insuring this does not happen again. The book gives you the tools you need to keep yourself and your family safe. Included are clever lift-out copies of the latest tornado safety rules for homes, schools, and offices.
