Naturally occurring salt tolerant and halophytic plants (trees, shrubs, grasses, and forbs) have always been utilized by livestock as a supplement or drought reserve. Salt tolerant forage and fodder crops are now being planted over wide areas. Increasingly, large-scale production of fodder on formerly abandoned irrigated cropland has allowed salt tolerant and halophytic feedstuffs to be mainstreamed into the supply chain for feedlots. Feeding salty feeds to livestock has been evaluated in many countries with good outcomes especially as a way to improve livestock nutrition and productivity. Better ways have been devised to use these potentially valuable feed resources. These feedstuffs are best fed in mixed rations. Substituting conventional fodder with up to 30 percent of the diets comprising halophytic feedstuffs have proved most successful for ruminant livestock but special formulations have been devised for poultry and rabbits. There are big savings on the import of costly feedstuffs and benefits to livelihoods of those dependent on scattered, sparse and unreliable forage/fodder in the world's drylands that cover about 40 percent of the world's land surface. This book is written by leading authorities from many different countries. It reviews past and current work on the animal-oriented aspects of the utilization of feedstuffs derived from salt tolerant and halophytic plants. It brings to the reader (scientist, researcher, academics and their students, policy makers, and livestock operators) an up-to-date analysis of the important issues related to salt-rich feedstuffs (nutrition, productivity, and reproduction).

Field naturalists have searched across Clare Island for animal groups ranging from the microscopic to birds and mammals. Many more species have been found since the original survey a hundred years ago, due to the availability of modern methods, which greatly add to our knowledge of the biodiversity of Clare Island. The lists of species featured here include some new to the island, some new to Ireland and some new to science. This volume signals the need for further field work and taxonomic research to track biodiversity changes arising from human activity. Land and freshwater fauna is the tenth volume in the New Survey of Clare Island series, which seeks to build on the pioneering work of the first Clare Island Survey (1909-11), the most ambitious natural history project ever undertaken in Ireland and the first major biological survey of a specific area carried out in the world.

This book provides an integrated description of methods used to rear vectors of human, higher animal, and plant pathogens in the laboratory. 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.

Human culture values some nonhumans but not others, while human culture as a whole is engaged with an incredibly diverse range of living beings. Animal studies is a growing interdisciplinary field that incorporates scholarship from public policy, sociology, religion, politics, philosophy, and many other fields. In essence, it seeks to understand how humans study and conceive of other-than-human animals, and how these conceptions have changed over time, across cultures, and among various scholarly modes of inquiry. This interdisciplinary introduction to the field boldly and creatively foregrounds the realities of nonhuman animals, as well as the imaginative and ethical faculties that humans must engage to consider our intersection with living beings outside of our species. The field requires both learning and unlearning to develop forms of critical thinking that are scientifically informed and ethically sensitive. This book is a frank assessment of the ways human-centered approaches undermine the core values of the scientific tradition, robust education, and human compassion. Further, it argues that the breadth and depth of thinking and the humility needed to grasp the human-nonhuman intersection has the potential to expand the dualism that currently divides the sciences and humanities. As the first holistic survey of the field, Animal Studies is essential reading for any student of human-animal relationships, and for all people who care about the role nonhuman animals play in our society.

'Intimate and thoughtful... Exciting... [A] sweeping evolutionary history.' Science The author of the bestselling Your Inner Fish gives us a brilliant, up-to-date account of the great transformations in the history of life on Earth. This is a story full of surprises. If you think that feathers arose to help animals fly, or lungs to help them walk on land, you'd be in good company. You'd also be entirely wrong. Neil Shubin delves deep into the mystery of life, the ongoing revolutions in our understanding of how we got here, and brings us closer to answering one of the great questions - was life on earth inevitable...or was it all an accident?

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).

However, no written summaries, covering the different types of pathogens being studied, developed and used for control, have previously - dressed this subje

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.

London Zoo examined in its nineteenth-century context, looking at its effect on cultural and social life. At the dawn of the Victorian era, London Zoo became one of the metropolis's premier attractions. The crowds drawn to its bear pit included urban promenaders, gentlemen menagerists, Indian shipbuilders and Persian princes - and Charles Darwin himself. This book shows that the impact of the zoo's extensive collection of animals can only be understood in the context of a wide range of contemporary approaches to nature, and that it was not merely a manifestation of British imperial culture. The author demonstrates how the early history of the zoo illuminates three important aspects of the history of nineteenth-century Britain: the politics of culture and leisure in a new public domain which included museums and art galleries; the professionalisation and popularisation of science in a consumer society; and the meanings of the animal world for a growing urban population. Weaving these threads together, he presents a flexible frame of analysis to explain how the zoo was established, how it pursued its policies of animal collection, and how it responded to changing social conditions.

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."

"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

Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.

IMAGINE A WORLD WHERE parasites control the minds of their hosts, sending them to their destruction.

IMAGINE A WORLD WHERE parasites are masters of chemical warfare and camouflage, able to cloak themselves with their hosts' own molecules.

IMAGINE A WORLD WHERE parasites steer the course of evolution, where the majority of species are parasites.

WELCOME TO EARTH.

For centuries, parasites have lived in nightmares, horror stories, and in the darkest shadows of science. Yet these creatures are among the world's most successful and sophisticated organisms. In Parasite Rex, Carl Zimmer deftly balances the scientific and the disgusting as he takes readers on a fantastic voyage. Traveling from the steamy jungles of Costa Rica to the fetid parasite haven of southern Sudan, Zimmer graphically brings to life how parasites can change DNA, rewire the brain, make men more distrustful and women more outgoing, and turn hosts into the living dead.

This thorough, gracefully written book brings parasites out into the open and uncovers what they can teach us about the most fundamental survival tactics in the universe.
