Important consideration is given to the contemporary cultural and ecological factors involved.

The Rise and Reign of the Mammals - A New History, from the Shadow of the Dinosaurs to Us (Hardcover): Steve Brusatte The Rise and Reign of the Mammals - A New History, from the Shadow of the Dinosaurs to Us (Hardcover)

'Steve Brusatte, the author of The Rise and Fall of the Dinosaurs, brings mammals out from the shadow of their more showy predecessors in a beautifully written book that . . . makes the case for them as creatures who are just as engaging as dinosaurs.' - The Sunday Times, 'Best Books For Summer' 'In this terrific new book, Steve Brusatte . . . brings well-known extinct species, the sabre-toothed tigers and the woolly mammoths, thrillingly back to life' - The Times The passing of the age of the dinosaurs allowed mammals to become ascendant. But mammals have a much deeper history. They - or, more precisely, we - originated around the same time as the dinosaurs, over 200 million years ago; mammal roots lie even further back, some 325 million years. Over these immense stretches of geological time, mammals developed their trademark features: hair, keen senses of smell and hearing, big brains and sharp intelligence, fast growth and warm-blooded metabolism, a distinctive line-up of teeth (canines, incisors, premolars, molars), mammary glands that mothers use to nourish their babies with milk, qualities that have underlain their success story. Out of this long and rich evolutionary history came the mammals of today, including our own species and our closest cousins. But today's 6,000 mammal species - the egg-laying monotremes including the platypus, marsupials such as kangaroos and koalas that raise their tiny babies in pouches, and placentals like us, who give birth to well-developed young - are simply the few survivors of a once verdant family tree, which has been pruned both by time and mass extinctions. In The Rise and Reign of the Mammals, palaeontologist Steve Brusatte weaves together the history and evolution of our mammal forebears with stories of the scientists whose fieldwork and discoveries underlie our knowledge, both of iconic mammals like the mammoths and sabre-toothed tigers of which we have all heard, and of fascinating species that few of us are aware of. For what we see today is but a very limited range of the mammals that have existed; in this fascinating and ground-breaking book, Steve Brusatte tells their - and our - story.

An immersive blend of chicken-keeping memoir and animal welfare reporting by a journalist who accidentally became obsessed with her flock. Since first domesticating the chicken thousands of years ago, humans have become exceptionally adept at raising them for food. Yet most people rarely interact with chickens or know much about them. In Under the Henfluence, Tove Danovich explores the lives of these quirky, mysterious birds who stole her heart the moment her first box of chicks arrived at the post office. From a hatchery in Iowa to a chicken show in Ohio to a rooster rescue in Minnesota, Danovich interviews the people breeding, training, healing and, most importantly, adoring chickens. With more than 60 billion chickens living on industrial farms around the world, they're easy to dismiss as just another dinner ingredient. Yet Danovich's reporting reveals the hidden cleverness, quiet sweetness and irresistible personalities of these birds, as well as the complex human-chicken relationship that has evolved over centuries. This glimpse into the lives of backyard chickens doesn't just help us to understand chickens better - it also casts light back on ourselves and what we've ignored throughout the explosive growth of industrial agriculture. Woven with delightful and sometimes heartbreaking anecdotes from Danovich's own henhouse, Under the Henfluence proves that chickens are so much more than what they bring to the table.

Development agencies have for years been seeking a successful universal response to deprivation. Sparked by controversy and debate, the most recent trend is to look for solutions among 'local' or 'indigenous' populations. Nevertheless, resources continue to be wasted in ill-conceived, centrally-imposed schemes that have not only failed to improve matters in lesser-developed countries but have often made them worse. In such instances it is not local knowledge that is problematic, but development agencies' total misinterpretation of it as just one more 'approach' that can be applied universally. Local knowledge can never be that panacea, because it is not in any sense generic. by illustrating that the potential of local knowledge, in development or elsewhere, can only be achieved through recognition of its essential plurality. Perspectives from leading ethnographers and development professionals on issues such as conservation, agriculture and resource management illustrate that the complexity and cultural specificity of local knowledges can only be accessed via equally diverse theories and methodological approaches. offers ways of advancing the relationship between local knowledge and development, and of furthering anthropology's role in development processes. As a rare example of serious study of local knowledge strategy and its applications, this book illustrates the growing need for real understanding of the issue and its power to assist in positive change.

This special issue illustrates benefits to animals from positive reinforcement training (PRT) and--depending on the setting--to scientists, animal care staff, veterinarians, and in the case of the zoo, the visiting public. One important theme throughout is that training is a joint venture between human and nonhuman primate and can lead to a closer, richer relationship between the two. In summary, the editors hope this issue encourages further and wider application of PRT to primate management, care, and use, as well as aid those working with animals in applying PRT safely and effectively.

Ethical Debates in Orangutan Conservation (Hardcover): Alexandra Palmer Ethical Debates in Orangutan Conservation (Hardcover)
Alexandra Palmer
R4,502 Discovery Miles 45 020 Ships in 10 - 15 working days

Ethical Debates in Orangutan Conservation explores how conservationists decide whether, and how, to undertake rehabilitation and reintroduction (R&R) when rescuing orphaned orangutans. The author demonstrates that exploring ethical dilemmas is crucial for understanding ongoing disagreements about how to help endangered wildlife in an era of anthropogenic extinction. Although R&R might appear an uncontroversial activity, there is considerable debate about how, and why, it ought to be practised. Drawing on in-depth qualitative research with orangutan conservation practitioners, this book examines how ethical trade-offs shape debates about R&R. For example, what if the orphan fails to learn how to be an orangutan again, after years in the company of humans? What if she is sent into the forest only to slowly starve? Would she have been better off in a cage? Could the huge cost of sending a rescued ape back to the wild be better spent on stopping deforestation in the first place? Or do we have a moral obligation to rescue the orphan regardless of cost? This book demonstrates that deconstructing ethical positions is crucial for understanding ongoing disagreements about how to help our endangered great ape kin and other wildlife. Ethical Debates in Orangutan Conservation is essential reading for those interested in conservation and animal welfare, animal studies, primatology, geography, environmental philosophy, and anthropology.

Beavers are widely recognised as a keystone species which play a pivotal role in riparian ecology. Their tree felling and dam building behaviours coupled with a suite of other activities create a wealth of living opportunities that are exploited by a range of other species. Numerous scientific studies demonstrate that beaver-generated living environments that are much richer in terms of both biodiversity and biomass than wetland environments from which they are absent. Emerging contemporary studies indicate clearly that the landscapes they create can afford sustainable, cost-effective remedies for water retention, flood alleviation, silt and chemical capture. Beaver activities, especially in highly modified environments, may be challenging to certain land use activities and landowners. Many trialled and tested methods to mitigate against these impacts, including a wide range of non-lethal management techniques, are regularly implemented across Europe and North America. Many of these techniques will be new to people, especially in areas where beavers are newly re-establishing. This handbook serves to discuss both the benefits and challenges in living with this species, and collates the wide range of techniques that can be implemented to mitigate any negative impacts. The authors of this handbook are all beaver experts and together they have a broad range of scientific knowledge and practical experience regarding the ecology, captive husbandry, veterinary science, pathology, reintroduction and management of beavers in both continental Europe and Britain.

R6,770 Discovery Miles 67 700 Ships in 10 - 15 working days

The spotted seatrout is an important species not only for recreational and commercial fisheries, but also as an integral part of many estuarine ecosystems. As one of the few fishes that live its entire life within an estuarine system, the species has tremendous potential as a monitor or sentinel for estuarine conditions. Prepared by the foremost authorities in their respective fields, Biology of the Spotted Seatrout presents an up-to-date summary of what is known about the basic biology of this important species.

This innovative reference provides current life history information on this species for the expressed purpose of beginning the task of assessing differences in estuarine restricted sub-populations of spotted seatrout. It serves as a model of a biological summary directed toward determining which of the life history parameters will most aptly serve as bioindicators to meet overall environmental management needs. It integrates estuarine specific life history features into the overall management of both estuaries and an estuarine dependent fishery.

Biology of the Spotted Seatrout includes a classic systematic approach to studying the relationships between seatrout genera as well as a more modern approach to investigating intra- and inter-estuarine differences in genetic structure. Ecologists, fisheries biologists and managers, and environmental scientists worldwide will be able to use the information presented in this book as a model on which to establish a database of information to be used to assess and compare estuarine conditions and environmental health. This valuable book serves as a blueprint for bringing together the biological criteria necessary to begin landscape scale comparisons of estuaries based on the biological information of totally estuarine dependent species, such as the spotted seatrout.

Mammalian oocytes occupy a critical nexus in reproduction as they not only contribute half the genetic makeup of the embryo but also provide virtually all of the cytoplasmic building blocks required for sustaining embryogenesis. The journey that transforms a primordial germ cell into a mature oocyte (or egg) capable of fertilisation and embryonic development is of unrivalled complexity. The end-product of this remarkable developmental process is the "mature" egg, now replete with macromolecules and organelles, and poised to support embryonic development if fertilisation should occur. Given the importance of the oocyte for embryonic development, it is of no surprise that the oocyte holds centre stage in fertility clinics and greatly influences the outcome of assisted reproductive treatments (ARTs). Mammalian Oocyte Regulation: Methods and Protocols provides a highly diverse compendium of detailed methodologies - primarily focusing on the murine model but also including chapters on human oocytes - for enabling researchers to interrogate every aspect of mammalian oocyte development including recombination, meiotic maturation, oocyte substrate uptake, chromosomal segregation and fertilisation. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Mammalian Oocyte Regulation: Methods and Protocols serves as an ideal guide to novice oocyte researchers, experts who wish to add another dimension to their established portfolio, as well as the wider research community.

Warren Zeiller
R833 Discovery Miles 8 330 Ships in 18 - 22 working days

This work is about the first manatee ever conceived and born in captivity. The pregnancy was long (about 13 months), the mother was huge (over 900 pounds), and baby Lorelei was regarded by Zeiller and his coworkers at the Miami Seaquarium as a truly blessed event. Even one addition to the dwindling number of this endangered species was reason to rejoice. Zeiller's knowledge of the history and plight of this docile sea mammal is based on his work at the Seaquarium, where he helped develop the only extant breeding herd of manatees (including Lorelei's parents, Romeo and Juliet), the only gene pool of the animal in captivity at that time. With more than 100 photographs that help to document his personal experiences, Zeiller describes ""mercy"" missions with the Mermaid Rescue Squad to liberate animals caught in drainage ditches or to care for animals injured by boat propellers. He relates his efforts and adventures with Captain Jacques Cousteau to return ""Sewer Sam"" to the freedom of Crystal River. In uncomplicated language he presents scientific information on the habitat, distribution, physiology, and feeding and breeding habits of the manatee and its relatives. Manatees are nearing extinction not because of public insensitivity, he believes, but because of a lack of knowledge. His intention throughout the book is to increase public awareness of the crises. ""Destroying or saving 60,000,000 years of evolution is in our hands"", he writes. And, from the Epilogue: ""We have named Lorelei's son (Juliet's grandson) Hugh.
