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.
Birds' eggs are true wonders of the natural world: they are strong enough to protect the embryo as it grows and to withstand incubation by the parent, yet sufficiently fragile to allow the chick to hatch. Little wonder that the enormous diversity of avian eggs - the amazing range of shapes, sizes, colours, textures and patterns - has long fascinated us. Since boyhood, the renowned landscape photographer Colin Prior has had a passion for wild birds. For him, birds are the embodiment of nature, and fundamentally enrich the experience of being outdoors. This stunning new book presents Prior's remarkable images of birds' eggs side by side with his dramatic photographs of the birds' natural habitats. At a time when many human influences are having an adverse impact on the environment, these habitats are equally fragile and vulnerable to change. Loss of habitat is, in turn, a major factor in the decline of wild bird populations. It has been illegal to take any birds' eggs from the wild in Great Britain since 1954, and since 1982 it has been against the law to possess the egg of any wild bird. The eggs featured in this book belong to the National Museum of Scotland in Edinburgh, which holds one of the world's largest collections of birds' eggs. The eggs were collected legally during the late 19th and early 20th centuries and bequeathed to the museum by private collectors. Prior set up a studio at the museum and spent five weeks photographing more than 300 eggs using the latest digital technology. Each photograph is a compilation of between 40 and 80 separate exposures that were then blended into a single image using specialist software. The final image is an exquisite, almost three-dimensional rendition of the egg, pin-sharp from the front to the back. The eggs vary in size from that of the tiny goldcrest, the UK's smallest bird, to that of the mute swan. In his introduction, Prior describes how his love of the natural world was nurtured by the endless hours he spent in the countryside around the Glasgow suburb where he grew up; how he overcame the technical challenges of photographing the eggs; how the featured eggs were selected from the museum's collection; and how the photography of each bird's habitat was completed. In his essay, the Scottish environmentalist Professor Des Thompson reflects on the state of nature and the relationship between nesting and habitats. In the main part of the book, the birds' eggs are arranged into chapters according to the species found in a particular habitat, such as 'Mountain and Moorland' and 'Seashore and Estuary'. The caption beneath each egg details the common and scientific name of the bird, the date the egg was collected, the size of the clutch, and the egg's dimensions. Each egg is presented in a diptych with a photograph of the bird's habitat, painstakingly captured at a time of year when the dominant colours of the landscape most closely resemble those of the egg. Fragile - the culmination of ten years' work - not only showcases the inherent beauty of birds' eggs, but also serves as a powerful reminder to protect the birds' natural habitats and thereby the birds themselves.
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.
Over the last decade, the study of shark biology has benefited from the development, refinement, and rapid expansion of novel techniques and advances in technology. These have given new insight into the fields of shark genetics, feeding, foraging, bioenergetics, imaging, age and growth, movement, migration, habitat preference, and habitat use. This pioneering book, written by experts in shark biology, examines technologies such as autonomous vehicle tracking, underwater video approaches, molecular genetics techniques, and accelerometry, among many others. Each detailed chapter offers new insights and promises for future studies of elasmobranch biology, provides an overview of appropriate uses of each technique, and can be readily extended to other aquatic fish and marine mammals and reptiles. Including chapter authors who were pioneers in developing some of the technologies discussed in the book, this book serves as the first single-source reference with in-depth coverage of techniques appropriate for the laboratory and field study of sharks, skates, and rays. It concludes with a unique section on Citizen Science and its application to studies of shark biology. This is a must-read for any marine biologist or scientist working in the field of shark biology, as well as marine biology students and graduates.

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.
Graham Martin takes the reader deep into the world of birds from a new perspective, with a 'through birds' eyes' approach to ornithology that goes beyond the traditional habitat or ecological point of view. There is a lot more to a bird's world than what it receives through its eyes. This book shows how all of the senses complement one another to provide each species with a unique suite of information that guides their daily activities. The senses of each bird have been fine-tuned by natural selection to meet the challenges of its environment and optimise its behaviour: from spotting a carcase on a hillside, to pecking at minute insects, from catching fish in murky waters, to navigating around the globe. The reader is also introduced to the challenges posed to birds by the obstacles with which humans have cluttered their worlds, from power lines to windowpanes. All of these challenges need explaining from the birds' sensory perspectives so that effective mitigations can be put in place. The book leads the reader through a wealth of diverse information presented in accessible text, with over 100 colour illustrations and photographs. The result is a highly readable and authoritative account, which will appeal to birdwatchers and other naturalists, as well as researchers in avian biology. The author has researched the senses of birds throughout a 50-year career in ornithology and sensory science. He has always attempted to understand birds from the perspective of how sensory information helps them to carry out different tasks in different environments. He has published papers on more than 60 bird species, from Albatrosses and Penguins, to Spoonbills and Kiwi. His first fascination was with owls and night time, and owls have remained special to him throughout his career. He has collaborated and travelled widely and pondered diverse sensory challenges that birds face in the conduct of different tasks in different habitats, from mudflats and murky waters, to forests, deserts and caves. In recent years he has focused on how understanding bird senses can help to reduce the very high levels of bird deaths that are caused by human artefacts; particularly, wind turbines, power lines, and gill nets.
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.
This monograph presents the results of over 10 years of paleontological and geological survey in the Baynunah Formation of the United Arab Emirates. Exposed widely in western Abu Dhabi Emirate, the Baynunah Formation and its fossils provide the only record of terrestrial environments and evolution in the Arabian Peninsula during the late Miocene epoch (12-5 Ma). This volume describes new fossils collected since 2002, presented systematically by taxon, and including mammals, reptiles, and invertebrates, as well as fossil trackways. The discoveries are framed within the results of new geological, geochemical, and geochrononological analyses, providing an updated and synthetic view of the age, environments, and biogeographic relationships of this important fossil assemblage.
This book provides a brief description of the ecology and natural history of sixteen amphibians, eight snakes and lizards and the Chelonia species found in the temperate climatic region of Europe (North-west Europe). The book commences with an introduction to the biology of amphibians and reptiles and describes the differences between the main groups. The main ecological adaptations are discussed and there is particular mention that it is erroneous to refer to amphibians and reptiles as cold blooded. There is also the suggestion that the colour of an amphibian or reptile may not necessarily mean anything in terms of the animal's thermal properties. For each species there is a brief account of the following: the etymology or origin of the name of the species, reference to early accounts of the species, taxonomy, protection, general description, distribution and habitat, seasonal movements and behaviour, vagility and population ecology, feeding ecology, thermal ecology, reproduction, growth and development, ge
This volume reviews, for the first time, the broad range of issues that affect the welfare of commercially farmed ratites. Although ratites incorporate several families of flightless birds this book focuses on the most commonly farmed ratites, the ostrich, emu and rhea. The readers are taken on a journey through all sectors of the industry, which include breeding, incubation, hatching, brooding, rearing, growth, transport and processing, with an emphasis on husbandry and management protocols that can impact bird welfare and health. Also discussed is the structure and sensory innervation of the skin and digits of the birds, and the potential welfare implications of industry practices on these structures. Each chapter in this volume focuses on a particular aspect of the commercial farming of ratites with contributing authors from a broad range of disciplines.
This new edition - now with Nancy Jackson as a co-author - continues the themes of the first edition: the need to restore the biodiversity, ecosystem health, and ecosystem services provided by coastal landforms and habitats, especially in the light of climate change. The second edition reports on progress made on practices identified in the first edition, presents additional case studies, and addresses new and emerging issues. It analyzes the tradeoffs involved in restoring beaches and dunes - especially on developed coasts - the most effective approaches to use, and how stakeholders can play an active role. The concept of restoration is broad, and includes physical, ecological, economic, social, and ethical principles and ideals. The book will be valuable for coastal scientists, engineers, planners, and managers, as well as shorefront residents. It will also serve as a useful supplementary reference textbook in courses dealing with issues of coastal management and ecology.
Biology of Marine Birds provides the only complete summary of information about marine birds ever published. It both summarizes and analyzes their breeding biology, ecology, taxonomy, evolution, fossil history, physiology, energetics, and conservation. The book covers four orders of marine birds: penguins (Sphenisciformes); albatross, shearwaters, petrels (Procellariiformes); pelicans, boobies, frigatebirds, tropicbirds, cormorants (Pelecaniformes); and gulls, terns, guillemots, auks (Charadriiformes - Families Laridae and Alcidae). Two summary chapters address the biology of shorebirds and wading birds and their lives in the marine environment.
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.
Thailand is probably the most popular destination for tourists in Asia, and birders have long travelled there to observe its wealth of wildlife. This comprehensive guide to the birds of Thailand is an indispensable field reference for birdwatchers, residents and visitors to the country alike. It covers all 950 species that have been recorded in Thailand, with 166 magnificent colour plates covering most plumage variations. Each plate is accompanied by concise text for each species and distinctive subspecies, detailing identification, voice, habitat and behaviour. In addition, there is a distribution map for every species, based on the very latest information.
Fish constitute an important natural renewable resource and any reduction in their ability to propagate as a result of human interference may have significant socioeconomic consequences. The negative effect of human activity on sex differentiation and reproductive output in fish is so diverse that it has been difficult to encompass it in a single book. This book serves as the first attempt to do so. Unlike in mammals, the expression of a host of sex differentiation genes in fish is mostly controlled by environmental factors. Not surprisingly, environmental sex differentiation is ubiquitous in fish. Overexploitation by capture fisheries does not disrupt sex differentiation but crowding in aqua-farms does, by reducing accessibility to food supply. Some of the man-made chemicals routinely used worldwide mimic endogenous hormones. For example endosulfan, which is widely used in developing countries, disrupts endogenous hormones and feminizes fish. For the first time, this book views endocrine disruption from the point of labile early life and non-labile adult stages. It shows that sex can irreversibly be reversed, when exposed to endocrine disrupting chemicals (EDCs) during early labile stages but reversibly impairs reproductive output on exposure to EDCs during non-labile adult stage. A consequence of climate change, elevated temperature, and declining oxygen and pH levels is that it masculinises genetic female fish. Fish display a remarkable ability to postpone the labile period. Besides postponement, some primary and tertiary gonochores have two distinct labile periods amenable to temperature and hormonal manipulations. Hermaphrodites have retained the period until the end of the adult stage and are capable of sex change/reversal more than once in both male and female directions.
Erythrocytes of the Rhesus and Cynomolgus Monkeys addresses the morphologic, quantitative, and generative aspects of the erythrocytes of the rhesus monkey Macaca mulatta and the cynomolgus monkey Macaca fascicularis (long-tailed macaque, crab-eating monkey). These two species are the most commonly selected nonhuman primates for basic science and clinical medical investigations. The hemopoietic cells of man and the rhesus monkey display an intimate homogeneity. Their functional activities are close and at times identical. The cynomolgus monkey was enlisted in biomedical studies at a time when rhesus monkeys were not available in sufficient quantities. It has gained increased use in the Far East and in the Western world. It is, for example, employed in the current development of a vaccine against the deadly Ebola virus. The authors of the book discuss the erythropoietic profiles of normal and abnormal macaques of both sexes and of all age groups as investigated with contemporary electronic methodologies. They cover the role of stress as it is perceived by the monkey and how it impacts erythrocellular values, and how to train the monkey to be a cooperative, unperturbed subject for hematologic study. Additional topics include the role of medication in deriving normal physiologic erythrocellular data, the development of the precursors of the erythrocyte (normoblasts), the morphologic analysis of the megaloblastic series of abnormal erythroid cells, the analysis of erythropoiesis in bone marrow, the relationship of the simian immunodeficiency virus and erythropoiesis, erythrocyte life span, and parasitic invasion of the red cell.
The marsupials are an important order of mammals that have evolved along lines parallel to eutherians. This book brings together what is known about one very important sense needed for survival - hearing. It documents various studies of the hearing capacities of marsupials and relates this information to their vocal behavior. To what sounds do marsupials respond? What are the spectra of their vocalizations? The organization of the brain auditory pathways of marsupials is compared with those of eutherian mammals and related to the structure of the auditory periphery. The fact that much of the early development of marsupial young occurs outside the mother's body enables the possibility of discoveries about the early development of brain and hearing relevant to all mammals. |
