"A redemption story, an adventure story, and perhaps above all, a love story."-Nate Blakeslee, New York Times-bestselling author of American Wolf The Druid Peak Pack was the most famous wolf pack in Yellowstone National Park, and maybe even in the world. This is the dramatic true story of its remarkable leader, Wolf 21-whose compassion and loyalty challenges commonly held beliefs about alpha males. In this compelling follow-up to the national bestseller The Rise of Wolf 8, Rick McIntyre profiles one of Yellowstone's most revered alpha males, Wolf 21. Leader of the Druid Peak Pack, Wolf 21 was known for his unwavering bravery, his unusual benevolence (unlike other alphas, he never killed defeated rival males), and his fierce commitment to his mate, the formidable Wolf 42. Wolf 21 and Wolf 42 were attracted to each other the moment they met-but Wolf 42's jealous sister interfered viciously in their relationship. After an explosive insurrection within the pack, the two wolves came together at last as leaders of the Druid Peak Pack, which dominated the park for more than 10 years. McIntyre recounts the pack's fascinating saga with compassion and a keen eye for detail, drawing on his many years of experience observing Yellowstone wolves in the wild. His outstanding work of science writing offers unparalleled insight into wolf behavior and Yellowstone's famed wolf reintroduction project. It also offers a love story for the ages. "Like Thomas McNamee, David Mech, Barry Lopez, and other literary naturalists with an interest in wolf behavior, McIntyre writes with both elegance and flair, making complex biology and ethology a pleasure to read. Fans of wild wolves will eat this one up."-Kirkus starred review

One of the main reasons that we organized this edited volume is to increase - ternational awareness of the growing use of invertebrate pathogens for control and eradication of invasive arthropods. As the numbers of invasive species continues to rise, more insect pathologists have been involved with work on their control using entomopathogens. In fact, this is not a new area of focus for insect pathologists; work on microbes against invasive arthropods began more than a century ago with classicalbiologicalcontrolintroductionsofentomopathogenicfungiagainstinvasive species in the 1890s. Chapters in this book cover entomopathogens that have been developedforcontrolofinvasivespeciesovermanydecades(e. g. anematodeagainst Sirex noctilio and Bacillus thuringiensis against gypsy moth) while other chapters focusondevelopmentofcontrolmeasuresforveryrecentinvasives(e. g. emeraldash borer?rstfoundintheUSin2002).

Within the past few years, symposia on use of microbes for invasive control have been organized twice at the annual meetings of the Society of Invertebrate Pathology (2005 - Anchorage, Alaska, and 2007 - Quebec City, Quebec, Canada), demonstrating interest in this subject across the international community of inv- tebrate pathologists. However, no written summaries, covering the different types of pathogens being studied, developed and used for control, have previously - dressed this subje

It deals with diverse subject areas, and contains descriptions of standard, as well as highly specialized, methods used by medical, veterinary, entomology, and plant pathology experts. The text brings together the standard breeding and manipulation methods developed in America, Europe, Asia, and Africa. It describes the cultivating, handling, sterile techniques, and cell culture as well as safety measures to prevent contamination and escape of insects, ticks, nematodes and fungal vectors.

A charming and quirky illustrated exploration of birds and the reasons we love them. From the Common Swift, which can stay in the air continuously without landing for up to ten months at a time, even sleeping on the wing, to the tiny Goldcrest, Europe's smallest bird, which can lay one-and-one-half times its body weight in eggs every season, birds are incredible creatures. With fascinating facts, humorous anecdotes and charming illustrations, artist Misha Blaise pays loving homage to the amazing birds that populate our skies in a delightful gift book sure to enchant birders, art-lovers, children and adults alike.

Jonathan Cranston is no ordinary vet. In addition to his day job in the Gloucestershire countryside treating cows, dogs, pigs and cats, he's also worked with an astonishing range of species around the world, including crocodiles, rhinos and pandas. In this charming collection he introduces us to some of his favourite patients, ranging from beloved family pets through to magnificent creatures of the wild. Whether microchipping armadillos, anaesthetising giraffes or birthing a calf, Jonathan's love for his work and the entire animal kingdom is infectious. From the preposterous (castrating a sugar glider) to the poignant (encountering victims of rhino poaching), the stories in The Travelling Vet will delight and enthral every animal lover.

Jean Octave Edmond Perrier was a French zoologist who lived through the tumult of British Darwinism and Lyellism, and reminds us in this revealing account that French scientists had much to contribute to such perennial topics as evolution, catastrophism and creationism. While very much a product of the Third Republic, Perrier's account also aimed to outline timeless issues and permanent advances in taxonomic and developmental biology since classical Greece and Rome. In this aim he succeeds with surprisingly modern perspectives for a book first published in 1884. Perrier was born May 9, 1844 at Tulle, the son of the principal of a school which now bears his name, Lycee Edmond Perrier. In 1864 he was accepted to the Ecole Normale Superieure, where he was strongly influenced by Louis Pasteur and Henri de Lacaze-Duthiers. After working for three years at a high school in Agen, he obtained a post of naturalist-aid at the Museum National d'Histoire Naturelle (1868), advancing in that institution to Chair of Natural History of Molluscs, Worms and Corals (1876-1903) and then Director of the museum (1900-1919) and Chair of Comparative Anatomy (1903-1921). Previous directors of the museum included many of the scientists he discusses in this book: George Cuvier (1822-1823, 1826-1827, 1830-1831), Isidore Geoffrey St Hilaire (1860- 1861), and Alphonse Milne-Edwards (1891-1900). Perrier's own research on echinoderms and earthworms took him on several expeditions in 1880-1885, mostly to Atlantic and Mediterranean coasts, but also to the Caribbean."

Discover nature's most colourful creatures in a major new book on colour in the animal kingdom. For many animals use of colour is essential to surviving in the wild. Both a built-in defence mechanism and a cunning tactic for attack, this biological advantage helps animals hide from dangerous predators and catch unsuspecting prey. It is used in many different ways, primarily to mask one's identity, movement or location, and changes over time as animals evolve and adapt to live. This stunning photographic collection reveals 100 creatures from around the world paired with fascinating insights from leading UK zoology author Steve Parker. Each animal will have a profile of 300 words paired with striking photographic examples featuring a wealth of colour and ingenious uses of colour for display or disguise. Learn how: The octopus can change its opacity, colour and pattern in response to threats. The walking leaf insect has evolved a strikingly similar shape and colour to the leaves it eats. The arctic fox changes its fur colour to white in the winter, perfectly blending in with the snow - but climate change is disrupting this age-old adaptation. This study of some of the most innovative uses of colour by animals, packed with beautiful photography and fascinating insights, will delight all lovers of the natural world.

This book provides a concise and up to date review of current knowledge on the biological processes affecting animal welfare, and the implications emerging from our improved understanding of those biological principles in terms of options available to assess and manage the welfare status of individuals and populations. Biological principles are embedded within wider consideration of the ethical basis for our concern about animals and their welfare, in recognition of the fact that concern and responsibility for welfare is strongly affected by cultural and ethical norms. The Biology and Management of Animal Welfare covers several topics not addressed in other texts. Thus it pays attention to the difference between animal welfare and animal rights and distinguishes between welfare and evolutionary fitness (which often causes confusion). The thorny problem of necessary versus unnecessary suffering is considered; most legislation provides for the prevention of unnecessary suffering but never defines it. In addition a box feature explores how human psychological development can affect attitudes to animals and how psychological dysfunctions (in terms of attitudes to other humans) can often be detected in advance from attitudes to animals. The book also includes consideration of alternatives to animal experimentation with a chapter devoted to the 3 Rs (Refine, Reduce, Replace). Written by authors who work in the field and all regularly contribute to postgraduate courses in animal welfare, in veterinary faculties and elsewhere, the text is deliberately kept short and concise to emphasise the essential principles, but is comprehensively referenced throughout in order to guide the reader in their own wider background reading around the framework provided by this overview. The book includes a number of dedicated box features that offer more detailed illustration or worked examples for some of the topics addressed in the text, or to focus attention on additional special topics.

This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.

Post-translational modifications serve many different purposes in several cellular processes such as gene expression, protein folding and transport to appropriate cell compartment, protein-lipid and protein-protein interactions, enzyme regulation, signal transduction, cell proliferation and differentiation, protein stability, recycling and degradation. Although several-hundred different modifications are known, the significance of many of them remains unknown. The enormous versatility of the modifications which frequently alter the physico-chemical properties of the respective proteins represents an extraordinary challenge in understanding their physiological role. Since essential cellular functions are regulated by protein modifications, an improvement of current understanding of their meaning might allow new avenues to prevent and/or alleviate human and animal diseases.

From the New York Times bestselling creators of Click, Clack, Moo, comes an entertaning introduction to politics. My fellow Americans: It is our pleasure, our honor, our duty as citizens to present to you Duck for President. Here is a duck who began in a humble pond. Who worked his way to farmer. To governor. And now, perhaps, to the highest office in the land. Some say, if he walks like a duck and talks like a duck, he is a duck. We say, if he walks like a duck and talks like a duck, he will be the next president of the United States of America. Thank you for your vote.

The rapid progress of neuroscience in the last decade can be largely attributed to significant advances in neuroethology, a branch of science that seeks to understand the neural basis of natural animal behavior. Novel approaches including molecular biological techniques, optical recording methods, functional anatomy, and informatics have brought drastic changes in how the neural systems underlying high-level behaviors such as learning and memory are described. This book introduces recent research techniques in neuroethology, with diverse topics involving nematodes, insects, and vertebrates (birds, mice and primates), divided into sections by research method. Each section consists of two chapters written by different authors who have developed their own unique approaches. Reports of research in model animals including "C." "elegans," " Drosophila, "and mice, which were not typical specimens in conventional neuroethology, have been deliberately selected for this book because a molecular genetic approach to these animals is necessary for advances in neuroethology. Novel methodology including optical recording and functional labeling with reporter genes such as GFP has been actively used in recent neurobiological studies, and genetic manipulation techniques such as optogenetics also are powerful tools for understanding the molecular basis of neural systems for animal behavior. This book provides not only these new strategies but also thought-provoking statements of philosophy in neuroethology for students and young researchers in the biological sciences."

This book presents a new perspective on the social milieu of the Early and Middle Neolithic in Central Europe as viewed through relations between humans and animals, food acquisition and consumption, as well as refuse disposal practices. Based on animal bone assemblages from a wide range of sites from a period of over 2,000 years originating in both the North European Plain lowlands and the loess uplands, the evidence explored in the book represents the Linear Band Pottery Culture (LBK), the Lengyel Culture, and the Funnel Beaker Culture (TRB) allowing us to follow the dynamic development of early farmers from their emergence in the area north of the Carpathians up to their consolidation and stabilization in this new territory.

This work examines the cognitive capacity of great apes in order to better understand early man and the importance of memory in the evolutionary process. It synthesizes research from comparative cognition, neuroscience, primatology as well as lithic archaeology, reviewing findings on the cognitive ability of great apes to recognize the physical properties of an object and then determine the most effective way in which to manipulate it as a tool to achieve a specific goal. The authors argue that apes (Hominoidea) lack the human cognitive ability of imagining how to blend reality, which requires drawing on memory in order to envisage alternative future situations, and thereby modifying behavior determined by procedural memory. This book reviews neuroscientific findings on short-term working memory, long-term procedural memory, prospective memory, and imaginative forward thinking in relation to manual behavior. Since the manipulation of objects by Hominoidea in the wild (particularly in order to obtain food) is regarded as underlying the evolution of behavior in early Hominids, contrasts are highlighted between the former and the latter, especially the cognitive implications of ancient stone-tool preparation.

Many Early Modern Europeans who during the sixteenth and seventeenth centuries travelled to the New World left written or pictorial records of their encounters with a surprising fauna. The story told in this book is woven out of the threads of those texts and pictures. A New World of Animals shows how the initial wonder at the new beasts gave way to a more utilitarian approach, assessing their economic and medical potential. It elucidates how shifts in European perceptions brought the animals from the realm of the fantastic into the mainstream of early modern natural history, while at the same time changing the way in which Europeans saw their own world. Indeed, the chronicles and treatises of those who in the wake of the discovery arrived in the new lands tell as much about the particular interests and mental worlds of the writers as about the 'new animals'. This book traces the amazement of the first explorers and colonizers, the chronicles of soldiers and Indians, the 'natural histories of the New World', the place of animals in the network of economic interests driving the early expansion of Europe, the views of the missionaries and those of natural philosophers and physicians. Taking the reader from the Brazilian forests to the erudite cabinets of the Old World, from Patagonia to the centres of empire, the story of the discovery of the unexpected menagerie of the New World is also an exploration of Early Modern European imagination and learning.
