Humans share a long history with carnivores. We fear them as predators, revile them as competitors, exploit them for their fur, or admire them for their grace and beauty. This book, the fifth of six volumes on the mammals of BC, provides comprehensive, up-to-date information on the 21 species of wild terrestrial carnivores in the province. Species covered: Coyote, Grey Wolf, Red Fox, American Black Bear, Grizzly Bear, Northern Raccoon, Sea Otter, Wolverine, Northern River Otter, American Marten, Fisher, Ermine, Long-tailed Weasel, Least Weasel, American Mink, American Badger, Striped Skunk, Western Spotted Skunk, Cougar, Canada Lynx, Bobcat. "Carnivores of British Columbia"describes each species, with illustrations of animals and skulls. For each species it discusses distribution and habitat, feeding ecology, social behaviour, reproduction, issues around health and mortality, abundance, human uses, conservation and management. This book will be an important educational reference for the general public, schools, naturalists and wildlife biologists.
Singing Like Larks opens a rare window onto the ancient song traditions of the British Isles, interweaving mesmerising lyrics, folklore and colourful nature writing to uncover the remarkable relationship between birds and traditional folk music. Birds are beloved for their song and have featured in our own music for centuries. This charming volume takes us on a journey of discovery to explore why birds appear in so many folk songs. Today, folk songs featuring our feathered friends are themselves something of a threatened species: their melodies are fading with the passage of time, and their lyrics are often tucked away in archives. It is more important than ever that we promote awareness of these precious songs and continue to pass them down the generations. Lifetimes of wisdom are etched into the words and music, preserving the natural rhythms of nature and our connection to times past. An important repository and treasury of bird-related folk songs, Singing Like Larks is also an account of one young nature writer’s journey into the world of folk music, and a joyous celebration of song, the seasons, and our love of birds.
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.
Sasol First Field Guide to Snakes & Other Reptiles of Southern Africa provides fascinating insight into the reptiles of the region. Through full-colour photographs and distribution maps, and easy-to-read text, the beginner and budding naturalist will be able to identify the more common species found in southern Africa, discover where they live, and learn about their unique feeding and nesting habits.
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.
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.
During the 20th century Xenopus has flourished as an accessible experimental model system for studying vertebrate biology. The second edition of Xenopus Protocols:Post-Genomic Approaches expands upon the previous edition with novel approaches inspired by Xenopus tropicalis and the sequencing of its genome. Xenopus tropicalis genomics and tractable genetics combined with the unique experimental advantages of Xenopus laevis and their distinctive phylogenetic position make them unique model systems for vertebrate embryonic development in the 21st century. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Xenopus Protocols: Post-Genomic Approaches, Second Edition provides a toolkit that will enable every laboratory to maximize the power of this extraordinary experimental system in the post-genomic age.
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
Previous experimental research has suggested that chimpanzees may understand some of the epitemological aspects of visual perception, such as how the perceptual act of seeing can have internal mental consequences for an individual's state of knowledge. Other research suggests that chimpanzees and other nonhuman primates may understand visual perception at a simpler level; that is, they may at least understand seeing as a mental event that subjectively anchors organisms to the external world. However, these results are ambiguous and are open to several interpretations. In this Monograph, we report the results of 15 studies that were conducted with chimpanzees and preschool children to explore their knowledge about visual perception.
'Brilliant, eye-opening, and absolutely inspiring - and a riveting read.' Cass Sunstein, author of How Change Happens and co-author of Nudge What is the secret to humanity's evolutionary success? Could it be our strength, our intellect... or something much nicer? From the authors of New York Times bestseller The Genius of Dogs comes a powerful new idea about how 'friendliness' is the key factor in the flourishing of our species. Hare and Woods present an elegant new theory called self-domestication, looking at examples of co-operation and empathy and what this can tell us about the evolutionary success of Homo sapiens...
Health and welfare issues of brachycephalic (flat-faced) animals are one of the most pressing problems facing companion animals right now. Dogs, in particular, are suffering from a 'brachycephalic crisis' resulting from a perfect storm where predispositions to an array of health issues are amplified by a population boom for certain brachycephalic breeds such as the French Bulldog and Pug. But yet, for many owners, these dogs represent the perfect companion: endearing personas and cute looks in a socially desirable package. So where is the truth in all of this? This book will equip veterinary professionals, animal welfare scientists, breeders and owners with the fuller story about brachycephalic health and welfare. The first half of the book provides the context of how and why we are in this crisis, offering in-depth historical, social, ethical, communication, nursing, welfare, epidemiological, genetics and international perspectives. The second half shifts towards the clinical arena, with chapters that cover the background, diagnosis, treatment and prevention of the many unique healthcare needs of brachycephalic animals. Cutting-edge knowledge is shared on a range of disciplines including respiratory disease, ophthalmology, dermatology, dentistry, neurology, obesity, reproduction and anesthesia. With twenty chapters written by world-leading experts, lifetimes of experience and knowledge are condensed into the first book dedicated exclusively to brachycephaly in companion animals. This essential reference resource will inform, challenge and stimulate; it will open your mind to new opportunities for you to improve the welfare of brachycephalic animals by your personal and collective choices and actions. But prepare to be surprised: you may just find that your views on brachycephaly in companion animals will be changed forever.
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.
Following the success of earlier ‘Quick Guide’ books, this slim little volume tackles one of the few groups of mammals that can fly. Divided into large fruit bats and smaller insecteating bats, this ultimate quick identification guide covers Africa’s 12 bat families. An informative introduction touches on evolution, flight, echolocation and reproduction, demystifying an animal that is all too often misunderstood. The text describes the facial characteristics and wing shapes common to each family and points out features that can help to distinguish between them. But it is the photographs and annotated line drawings that are most useful for identification. They include bats in flight and roosting sites, and close-ups of facial structures and wings that highlight key diagnostic attributes. An added extra is a photographic section showing the skulls of a variety bats. This is a valuable guide for anyone with an interest in wildlife and its less common members.
A charismatic and arresting bird, the Painted Stork inhabits the plains and wetlands of India and Southeast Asia. This near-threatened species provides a good model through which to explore a variety of ecology and conservation issues. As a colonial nester, it is also useful for considering questions related to evolution and the development of avian coloniality. The Painted Stork sometimes nests opportunistically in the middle of large cities – the Delhi Zoo colony, for instance, has been active since 1960. This offers a splendid opportunity to study the species at close range, as attested by this book's lively photographic component. The Painted Stork is an important indicator of its wetland habitats, which themselves are highly threatened. Since environmental toxins, particularly organochlorine pesticides, travel rapidly along aquatic food chains, the study of piscivorous birds like the Painted Stork assumes special significance. Equally vulnerable today are the nesting colonies, located in marshes, village reservoirs and the wider countryside, including in urban settings. Perhaps because their natural nesting areas are becoming scarce due to habitat loss, colonial waterbirds look for suitable sites in parks and gardens. Hence, the behaviour of this species reflects changes occurring in its environment. Birds also help us monitor the effects of global climate change, and one of the most significant dimensions of the Painted Stork is its dependence upon the monsoon. How exactly do these seasonal rains govern the food cycles in wetlands? And what happens when the monsoon fails? Covering all aspects of Painted Stork ecology, behaviour, conservation and its relationship with humans, this accessible monograph contains a wealth of new insights.
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.
In this dazzling literary collection, writers explore and celebrate their lives with and love for birds-detailing experiences from Alaska to Bermuda, South Dakota to Panama. In When Birds Are Near, fresh new voices as well as seasoned authors offer tales of adventure, perseverance, and fun, whether taking us on a journey down Highway 1 to see a rare California Condor, fighting the destruction of our grasslands, or simply watching the feeder from a kitchen window. But these essays are more than just field notes. The authors reflect on love, loss, and family, engaging a broad array of emotions, from wonder to amusement. As Rob Nixon writes, "Sometimes the best bird experiences are defined less by a rare sighting than by a quality of presence, some sense of overall occasion that sets in motion memories of a particular landscape, a particular light, a particular choral effect, a particular hiking partner." Or, as the poet Elizabeth Bradfield remarks, "We resonate with certain animals, I believe, because they are a physical embodiment of an answer we are seeking. A sense of ourselves in the world that is nearly inexpressible." When Birds Are Near gives us the chance to walk alongside these avid appreciators of birds and reflect on our own interactions with our winged companions.

The perfect companion for any wildlife-friendly visitor, Birds of the Middle East provides photographic coverage of more than 320 species that regularly occur in the region. Concise text for each species includes information on identification, songs and calls, behaviour, distribution and habitat, with each photo having been carefully selected to guide identification. A guide to the best birdwatching sites in the Middle East is also included. Portable yet authoritative, this is the perfect guide for travellers and birdwatchers visiting this spectacular and bird-rich slice of western Asia.
An introduction to France for anyone visiting with birds in mind, from casual birdwatchers checking a bird that flies over the terrace during a family holiday to addict birders who would sell their souls for a dream species or a record-breaking checklist. Some may have just a few spare hours to get their binoculars out between business meetings or museum visits, others will be out in the field for two weeks or more, from sunrise to sunset. The authors wrote this book for all bird lovers, birdwatchers and birders, whatever the duration of their stay, the number of kilometres they are prepared to travel and how they enjoy birds. With over 400 regularly occurring species, of which 357 normally breed or winter, France has one of the most diverse avifaunas of the whole of Europe, spanning an incredible range from colourful Mediterranean flagship species such as roller, bee-eater or black-winged kite to secretive cold-climate or mountain specialists like three-toed woodpecker and Tengmalm's owl. The Birdfinder section provides targeted details for 30 species which often rank in the top wish-list of birders visiting France. Dividing the country into 14 regions, the authors highlight 312 representative sites, chosen for their bird species composition and ease of access. The selected sites enable the reader to see the widest possible species diversity and largest range of local specialities in a reasonable time, while respecting the basic ethical rules obvious to all birdwatchers. Whenever possible, sites are arranged in clusters or itineraries that can be covered in two to three days without hurrying. To supplement the use of the book in the field, all the sites described are geolocated in a file that can be downloaded from the publisher's website and loaded onto any GPS device.
Shorebirds, or waders, are a large group of small to medium-sized birds that occur worldwide, in a wide range of predominantly coastal or wetland habitats. Some species are largely sedentary whilst others are amongst the world's most migratory bird species, travelling thousands of kilometres in a few days. In addition to describing physical behavioural traits such as feeding, breeding, migration, and particular physiological adaptations, Shorebirds in Action also covers territorial behaviour both when feeding and breeding. There is detailed discussion of the range of species and their different lifestyles together with feeding strategies, flocking, roosting and the avoidance of predators. The seasonal features of shorebirds' lives are included, such as the various plumages that they have when breeding, or not breeding, together with the intervening periods of moult, during which the birds change from one plumage to the next.Shorebirds in Action is in two parts - firstly basic behavioural information and then a photographic section that explains the specific behaviour being illustrated for that particular shorebird at the time the photo was taken.Consequently, the book can be read as a general text, split into chapters that provide the basic behavioural information and also by reference to the extended photograph captions which explain the details of the particular behaviour shown. The book contains excellent photographs of about 180 shorebird species - over three-quarters of the world's total - and therefore provides a general reference for the identification of shorebird species and the recognition of their various plumages. It will be relevant to readers worldwide, including Europe, North America and Australasia. This comprehensive work can be read as a general text and also the photographs can be enjoyed separately in their own right. Detailed references to source material are provided.
This volume is the third and final part of the planned coverage of the neurochemical circuitry of the primate central nervous system. The five chapters included in this volume complement and integrate magnificently with the two prior volumes.
