Book Description
Sea otters are good indicators of ocean health. In addition, they are a keystone species, offering a stabilizing effect on ecosystem, controlling sea urchin populations that would otherwise inflict damage to kelp forest ecosystems. The kelp forest ecosystem is crucial for marine organisms and contains coastal erosion. With the concerns about the imperiled status of sea otter populations in California, Aleutian Archipelago and coastal areas of Russia and Japan, the last several years have shown growth of interest culturally and politically in the status and preservation of sea otter populations. Sea Otter Conservation brings together the vast knowledge of well-respected leaders in the field, offering insight into the more than 100 years of conservation and research that have resulted in recovery from near extinction. This publication assesses the issues influencing prospects for continued conservation and recovery of the sea otter populations and provides insight into how to handle future global changes. - Covers scientific, cultural, economic and political components of sea otter conservation - Provides guidance on how to manage threats to the sea otter populations in the face of future global changes - Highlights the effects that interactions of coastal animals have with the marine ecosystem

Book Description
Written over several decades and collected together for the first time, these richly detailed contextual studies by a leading historian of science examine the diverse ways in which cultural values and political and professional considerations impinged upon the construction, acceptance and applications of nineteenth century evolutionary theory. They include a number of interrelated analyses of the highly politicised roles of embryos and monsters in pre- and post- Darwinian evolutionary theorizing, including Darwin’s; several studies of the intersection of Darwinian science and its practitioners with issues of gender, race and sexuality, featuring a pioneering contextual analysis of Darwin’s theory of sexual selection; and explorations of responses to Darwinian science by notable Victorian women intellectuals, including the crusading anti-feminist and ardent Darwinian, Eliza Lynn Linton, the feminist and leading anti-vivisectionist Frances Power Cobbe, and Annie Besant, the bible-bashing, birth-control advocate who confronted Darwin’s opposition to contraception at the notorious Knowlton Trial.

Book Description
In Geographies of Nineteenth-Century Science, David N. Livingstone and Charles W. J. Withers gather essays that deftly navigate the spaces of science in this significant period and reveal how each is embedded in wider systems of meaning, authority, and identity. Chapters from a distinguished range of contributors explore the places of creation, the paths of knowledge transmission and reception, and the import of exchange networks at various scales. Studies range from the inspection of the places of London science, which show how different scientific sites operated different moral and epistemic economies, to the scrutiny of the ways in which the museum space of the Smithsonian Institution and the expansive space of the American West produced science and framed geographical understanding. This volume makes clear that the science of this era varied in its constitution and reputation in relation to place and personnel, in its nature by virtue of its different epistemic practices, in its audiences, and in the ways in which it was put to work.

Book Description
This title was first published in 2000: The noble goals embodied in the Endangered Species Act are colliding with financial and social realities. Citizens increasingly face the costs of current policies, while initiatives which fail to respect liberty and property meet serious resistance at every turn. Despite widespread verbal support for saving species ’at any cost’, when trade-offs become obvious, and values compete, support for these policies evaporates. This edited collection examines ethically and materially responsible approaches to this problem, written by leading international figures from a variety of disciplines. The result is the most comprehensive and constructive analysis of the effectiveness and viability of endangered species protection available.

Book Description
The first comprehensive synthesis on development and evolution: it applies to all aspects of development, at all levels of organization and in all organisms, taking advantage of modern findings on behavior, genetics, endocrinology, molecular biology, evolutionary theory and phylogenetics to show the connections between developmental mechanisms and evolutionary change. This book solves key problems that have impeded a definitive synthesis in the past. It uses new concepts and specific examples to show how to relate environmentally sensitive development to the genetic theory of adaptive evolution and to explain major patterns of change. In this book development includes not only embryology and the ontogeny of morphology, sometimes portrayed inadequately as governed by "regulatory genes," but also behavioral development and physiological adaptation, where plasticity is mediated by genetically complex mechanisms like hormones and learning. The book shows how the universal qualities of phenotypes--modular organization and plasticity--facilitate both integration and change. Here you will learn why it is wrong to describe organisms as genetically programmed; why environmental induction is likely to be more important in evolution than random mutation; and why it is crucial to consider both selection and developmental mechanism in explanations of adaptive evolution. This book satisfies the need for a truly general book on development, plasticity and evolution that applies to living organisms in all of their life stages and environments. Using an immense compendium of examples on many kinds of organisms, from viruses and bacteria to higher plants and animals, it shows how the phenotype is reorganized during evolution to produce novelties, and how alternative phenotypes occupy a pivotal role as a phase of evolution that fosters diversification and speeds change. The arguments of this book call for a new view of the major themes of evolutionary biology, as shown in chapters on gradualism, homology, environmental induction, speciation, radiation, macroevolution, punctuation, and the maintenance of sex. No other treatment of development and evolution since Darwin's offers such a comprehensive and critical discussion of the relevant issues. Developmental Plasticity and Evolution is designed for biologists interested in the development and evolution of behavior, life-history patterns, ecology, physiology, morphology and speciation. It will also appeal to evolutionary paleontologists, anthropologists, psychologists, and teachers of general biology.

Book Description
In Victorian Skin, Pamela K. Gilbert uses literary, philosophical, medical, and scientific discourses about skin to trace the development of a broader discussion of what it meant to be human in the nineteenth century. Where is subjectivity located? How do we communicate with and understand each other's feelings? How does our surface, which contains us and presents us to others, function and what does it signify? As Gilbert shows, for Victorians, the skin was a text to be read. Nineteenth-century scientific and philosophical perspectives had reconfigured the purpose and meaning of this organ as more than a wrapping and instead a membrane integral to the generation of the self. Victorian writers embraced this complex perspective on skin even as sanitary writings focused on the surface of the body as a dangerous point of contact between self and others. Drawing on novels and stories by Dickens, Collins, Hardy, and Wilde, among others, along with their French contemporaries and precursors among the eighteenth-century Scottish thinkers and German idealists, Gilbert examines the understandings and representations of skin in four categories: as a surface for the sensing and expressive self; as a permeable boundary; as an alienable substance; and as the site of inherent and inscribed properties. At the same time, Gilbert connects the ways in which Victorians "read" skin to the way in which Victorian readers (and subsequent literary critics) read works of literature and historical events (especially the French Revolution.) From blushing and flaying to scarring and tattooing, Victorian Skin tracks the fraught relationship between ourselves and our skin.

Book Description
How should historians speak truth to power – and why does it matter? Why is five hundred years better than five months or five years as a planning horizon? And why is history – especially long-term history – so essential to understanding the multiple pasts which gave rise to our conflicted present? The History Manifesto is a call to arms to historians and everyone interested in the role of history in contemporary society. Leading historians Jo Guldi and David Armitage identify a recent shift back to longer-term narratives, following many decades of increasing specialisation, which they argue is vital for the future of historical scholarship and how it is communicated. This provocative and thoughtful book makes an important intervention in the debate about the role of history and the humanities in a digital age. It will provoke discussion among policymakers, activists and entrepreneurs as well as ordinary listeners, viewers, readers, students and teachers. This title is also available as Open Access.
