In this fascinating account of scientific study among forbidding wilderness, a husband-and-wife team describe their trek to the Kalahari to study the little-known brown hyena. The details of the scientific inquiry are provided while the daily challenges of living with children 420 kilometers from the nearest town are described. Despite the hardships, the couple becomes so enchanted by these intelligent animals that they stay for 12 years, documenting many hyena clans and observing behavior only a handful of people have ever seen.
Despite their low species density, hyenas are both unique and vital components of most African and some Asian ecosystems. Although there are only 4 species, they tend to clash with the interests of humans to a greater extent than many other mammals and one of the biggest obstacles facing those committed to the conservation of this species is the negative feelings that many people have towards hyenas. This action plan sets out to address some of the problems facing this species of animal, particularly the issue of public perception and awareness, and provides guidelines to rectify this situation.
The mammalian order Carnivora is characterized by an incredible range of morphological, ecological, and behavioral variation. Carnivores can be as small as the 100-gram least weasel or as large as the 800-kilogram polar bear. Their reproductive rate can vary from one offspring every five years, as with some black bears, to three litters a year, as with the dwarf mongoose. Group sizes can be traced along a wide continuum, from the solitary ermine to the monogamous golden jackal to the large extended packs of as many as 80 spotted hyenas. Until recently the general habits of most wild carnivore species were inadequately understood. In the last decade, however, improved technologies, including the use of radiotelemetry and night-vision scopes, have led to many important discoveries. This book is at once a critical summary and an evaluation of current research on carnivores. A worthy successor to R.F. Ewer's monumental volume, The Carnivores (Cornell University Press), it is the work of 30 leading carnivore biologists, who here assemble comparative data on the basic anatomical, behavioral, ecological, physiological, reproductive, and evolutionary characteristics of this group. After a general introduction to the Carnivora, the volume is divided in three parts, each of which begins with a brief introduction outlining its main themes. Part I, Behavior, covers acoustic and olfactory communication, behavioral development, behavioral ecology of canids and hyaenids, modes of solitary living, and group living. In Part II, Ecology, topics include feeding ecology of the giant panda and Asiatic black bear, adatpations for aquatic living, ecological constraints on predation in felids, consequences of small size in mustelids, rate of basal metabolism and food habits, and reproductive output. Part III, Evolution, deals with the morphological approaches to phylogeny, and the fossil record. An appendix presents a complete classification of the Carnivora, including topics of continuing controversy. Highlighting recent developments in the study of the Carnivora and areas for further research, this broad synthesis will be of great value of students and researchers in animal behavior, behavioral ecology, wildlife ecology, mammalogy, paleontology, systematics, and evolution theory. It will also encourage realistic conservation programs to manage rapidly diminishing populations and will elucidate particular features of the carnivores for nonspecialist readers.
An ordered and scientific study of the ecology of all African carnivores larger than jackals. Numerous colour photographs taken by both authors, and excellent sketches by the internationally renowned wildlife artist Clive Walker, depict the life and habitat of these carnivores.
This the first detailed study of the cheetah in an arid environment, addressing topics such as optimal foraging theory, hunting strategies and predator prey relations, mating systems, reproductive strategies and success, inter-specific competition, demography, social organisation, and population limitation.
"This is the story of the Owens' travel and life in the Kalahari Desert, [where] they met and studied unique animals and were confronted with danger from drought, fire, storms, and the animals they loved"--Amazon.com.
The succulent and Nama-karoo form part of the arid south-western zone of Africa, a vast region of rugged landscapes and low treeless vegetation. Studies of this unique biome have yielded fascinating insights into the ecology of its flora and fauna. This book, originally published in 1999, is the first to synthesise these studies, presenting information on biogeographic patterns and life processes, form and function of animals and plants, foraging ecology, landscape-level dynamics and anthropogenic influences. Detailed analyses of the factors distinguishing the biota of the Karoo from that of other temperate deserts are given and generalisations about semi-arid ecosystems challenged. The ideas expounded, the ecological principles reviewed, and the results presented are relevant to all those working in the extensive arid and semi-arid regions of the world.
Although they are highly intelligent, ruthless predators, carnivores are increasingly rare. From the dwarf mongoose to the polar bear, carnivores are at once respected and misunderstood, invoking both fear and curiosity in the humans with whom they share their world. Ronald M. Nowak celebrates these fascinating mammals in Walker's Carnivores of the World. This comprehensive guide, featuring 225 illustrations, covers the world's eight terrestrial families of carnivores. Each generic account comprises scientific and common names, number and distribution of species, physical attributes, measurements, hunting and social activity, reproduction, habitat, population dynamics, longevity, and status of threatened species. A thought-provoking overview by David W. Macdonald and Roland W. Kays is packed with results of the latest field and laboratory research on topics ranging from evolutionary history to the adaptive value of fur patterns. Emphasizing the interplay of social life, morphology, and predatory behavior, it provides an up-to-date panorama of the world's carnivores.
Hyenas are almost universally regarded as nasty, scheming charlatans that skulk in the back alleyways of the animal kingdom. They have been scorned for centuries as little more than scavenging carrion-eaters, vandals, and thieves. Here to restore the Hyena’s reputation is Mikita Brottman, who offers an alternate view of these mistreated and misunderstood creatures and proves that they are complex, intelligent, and highly sociable animals. Investigating representations of the hyena throughout history, Brottman divulges that the hyena, though shrouded in taboo, has been the source of talismanic objects since the ancient Greek and Roman empires. She discovers that many cultures use parts of the hyena—from excrement and blood to genitalia and hair—to make charms that both avert evil and promote fertility. Brottman also considers representations of hyenas in today’s popular fiction, including The Lion King and The Life of Pi,where they are often depicted as villains, cowardly henchmen, or clowns, while ignoring their more noble qualities. Rightly returning hyenas to their proper place in the animal pantheon, this richly illustrated book will be enjoyed by any animal lover with an interest in the unusual and offbeat.
The current volume focuses on behavioral similarities and differences within individual animals, larger populations, and species as a whole. Research from ecological, social ontogenetic, physiological, and other perspectives is presented to explicate specific behaviors, as well as to provide a more profound understanding of how behavior work influences thought about evolutionary processes.
