Early Life History of Marine Fishes Cover

Early Life History of Marine Fishes

Bruce Miller

The life cycles of fishes are complex and varied, and knowledge of the early life stages is important for understanding the biology, ecology, and evolution of fishes. In Early Life History of Marine Fishes, Bruce S. Miller and Arthur W. Kendall Jr., bring together in a single reference much of the research available and its application to fishery science—knowledge increasingly important because for most fishes, adult populations are determined at the earliest stages of life. Clear and well written, this book offers expert guidance on how to collect and analyze larval fish data and on how this information is interpreted by applied fish biologists and fisheries managers.

Early Modern Human from Tianyuan Cave, China

By Hong Shang and Erik Trinkaus

For more than a century, scientists have returned time and again to the issue of modern human emergence-the when and where of the evolutionary process and the human behavioral and biological dynamics involved. The 2003 discovery of a human partial skeleton at Tianyuandong (Tianyuan Cave) excited worldwide interest. The first human skeleton from the region to be directly radiocarbon-dated (to 40,000 years before present), its geological age places it close to the time period during which modern humans became permanently established across the Old World (between 50,000 and 35,000 years ago). Through detailed description and interpretation of the most complete early modern human skeleton from eastern Asia, The Early Modern Human from Tianyan Cave, China, addresses long-term questions about the ancestry of modern humans in eastern Asia and the nature of the changes in human behavior with the emergence of modern human biology. This book is a detailed, paleontological and paleobiological presentation of this skeleton, its context, and its implications. By providing basic information for this important human fossil, offering inferences concerning the population processes involved in modern human emergence in eastern Eurasia, and by raising questions concerning the adaptations of these early modern human hunter-gatherers, The Early Modern Human from Tianyuan Cave, China will take its place as a core contribution to the study of modern human emergence.

Ecology of Fragmented Landscapes

Sharon K. Collinge foreword by Richard T. T. Forman

Ask airline passengers what they see as they gaze out the window, and they will describe a fragmented landscape: a patchwork of desert, woodlands, farmlands, and developed neighborhoods. Once-contiguous forests are now subdivided; tallgrass prairies that extended for thousands of miles are now crisscrossed by highways and byways. Whether the result of naturally occurring environmental changes or the product of seemingly unchecked human development, fractured lands significantly impact the planet’s biological diversity. In Ecology of Fragmented Landscapes, Sharon K. Collinge defines fragmentation, explains its various causes, and suggests ways that we can put our lands back together. Researchers have been studying the ecological effects of dismantling nature for decades. In this book, Collinge evaluates this body of research, expertly synthesizing all that is known about the ecology of fragmented landscapes. Expanding on the traditional coverage of this topic, Collinge also discusses disease ecology, restoration, conservation, and planning. Not since Richard T. T. Forman's classic Land Mosaics has there been a more comprehensive examination of landscape fragmentation. Ecology of Fragmented Landscapes is critical reading for ecologists, conservation biologists, and students alike.

Elements of African Bioethics in a Western Frame Cover

Elements of African Bioethics in a Western Frame

For millennia, Africans have lived on the African continent, in close contact with the diversities of nature: floral, faunal and human; and in so doing they have developed cultures, values, attitudes and perspectives to the problems, ethical and otherwise, that have arisen from the existential pressures of their situation. The problem, however, is that such values and perspectives do not necessarily form coherent ethical theories. Theory-making is a second order activity requiring a certain amount of leisure and comfort which the existential conditions of life on the African continent have not easily permitted in the retrospect-able past. The elements of African bioethics are to be found in its cultural values, traditions, customs and practices. These are research-able, highlight-able and usable by those who would. The bioethical problems of our current global existential situation are such that all possible solutions, no matter their provenance, ought to be tried. Western culture†has far too loud a voice combined with deaf ears in contemporary ethical discourse. But it should never be forgotten that other cultures†have their own word to say and that alternative values, ways of thinking and practices exist, and attempt should always be made to bring these out and to highlight them, if they could possibly contribute to the satisfactory solution of a global problem. This book brings together various papers on bioethical issues and problems, written at different times, some previously published, each of which attempts to bring out some African†elements, perspective or concern. The African narrative style predominates through these essays but their framing conforms, more or less, to the Western paradigm for presenting academic issues.

Emerging Avian Disease Cover

Emerging Avian Disease

Published for the Cooper Ornithological Society

Ellen Paul

In this volume, new human disease pandemics, arising from animals stimulated by ongoing environmental change, demonstrate the value of ornithological research into avian diseases. A group of 29 researchers addresses a diverse set of topics, including the evolutionary and ecological aspects of the host-vector systems, the effects of genetic variation, introduction success and vector ecology, evolution of resistance and virulence of pathogens, and the effects of changing geographic distributions. In addition to empirical studies under field conditions, the authors present predictive models to assess the movement and potential impact of these diseases. Other chapters delve into the potential impacts of pathogens and the key role of biosurveillance and documenting impacts of disease on bird populations.

Encyclopedia of Tidepools and Rocky Shores

Mark W Denny

Tidepools and rocky shores are among the most physically stressful environments on earth. When the tide is high, waves can sweep over plants and animals at velocities as high as 60 miles per hour, while at low tide, the same organisms dry up and bake in the sun. Yet despite this seeming inhospitality, tidepools and rocky shores are exceptionally complex and biologically diverse. This comprehensive encyclopedia is an authoritative, one-stop reference for everyone interested in the biology and ecology of this fascinating and uniquely accessible environment. Conveniently arranged alphabetically, nearly 200 wide-ranging entries written in clear language by scientists from around the world provide a state-of-the-art picture of tidepools and rocky shore science. From Abalones, Barnacles, and Climate Change through Seagrasses, Tides, and Wind, the articles discuss the animals and plants that live in tidepools, the physics and chemistry of the rocky shore environment, the ecological principles that govern tidepools, and many other interdisciplinary topics.

* Generously illustrated with hundreds of color photographs, drawings, and diagrams

* The only comprehensive volume available on tidepools and rocky shores

* Articles include in-depth looks at animal and algal diversity and overviews of the history of research, rocky shore management, and conservation

* Contributors are experts on physics and physical oceanography, experimental ecology, population genetics, taxonomy, and other disciplines

Entertaining Elephants

Animal Agency and the Business of the American Circus

Susan Nance

Consider the career of an enduring if controversial icon of American entertainment: the genial circus elephant. In Entertaining Elephants Susan Nance examines elephant behavior—drawing on the scientific literature of animal cognition, learning, and communications—to offer a study of elephants as actors (rather than objects) in American circus entertainment between 1800 and 1940. By developing a deeper understanding of animal behavior, Nance asserts, we can more fully explain the common history of all species. Entertaining Elephants is the first account that uses research on animal welfare, health, and cognition to interpret the historical record, examining how both circus people and elephants struggled behind the scenes to meet the profit necessities of the entertainment business. The book does not claim that elephants understood, endorsed, or resisted the world of show business as a human cultural or business practice, but it does speak of elephants rejecting the conditions of their experience. They lived in a kind of parallel reality in the circus, one that was defined by their interactions with people, other elephants, horses, bull hooks, hay, and the weather. Nance’s study informs and complicates contemporary debates over human interactions with animals in entertainment and beyond, questioning the idea of human control over animals and people's claims to speak for them. As sentient beings, these elephants exercised agency, but they had no way of understanding the human cultures that created their captivity, and they obviously had no claim on (human) social and political power. They often lived lives of apparent desperation.

Environmental Safety of Genetically Engineered Crops

Rebecca Grumet

Since the mid-1990s, when the technology was first introduced, the cultivation of genetically engineered (GE) crops has grown exponentially. In the U.S. alone, adoption rates for transgenic cotton, corn, and soybeans are between 70–90%. Across the globe, 14 million farmers grow GE crops in more than twenty countries. Yet many countries are discussing and debating the use and adoption of GE technology because of concerns about their impact on the environment and human health. Now, in this comprehensive handbook, a team of international experts present the scientific basis for GE crops, placing them in the context of current agricultural systems, and examining the potential environmental risks posed by their deployment. An integrated approach to an increasingly hot and globally debated topic, the book considers the past, present, and future of GE crops, and offers an invaluable perspective for regulation and policy development.
