Available in PDF, EPUB and Kindle. Book excerpt: The endangered red wolf (Canis rufus) was preserved in captivity with just 14 founders following its planned extirpation in the wild. Longitudinal reproductive events were investigated to determine whether inbreeding, parental age, and breeding experience were factors in reproductive performance and fitness. A behavioral preference study using olfactory presentations of conspecific and congeneric social odors also was conducted to determine those factors that are important in the selection of mates. Over 30 years of managed breeding, the level of inbreeding in the captive population has increased, and litter size has declined. Inbreeding levels were lower in sires and dams that reproduced than in those that did not reproduce, but there was no difference in the level of inbreeding of actual and predicted litters. Litter size was negatively affected by offspring and paternal levels of inbreeding, but the effect of inbreeding on offspring survival was restricted to a positive influence. Younger wolves were more likely to reproduce, and were more likely to produce larger litters, than were older individuals. The age of the dam, but not the sire, had a significant negative effect on pup survival. Sires and dams that had prior experience in the production of offspring were more likely to reproduce again than were individuals without prior reproductive success, but prior sexual experience alone was not a factor in the production of offspring. Parental breeding experience had a significant negative effect on pup survival, but no apparent relationships with size or sex ratio of the litter. In general, females responded to the presentation of social odors of conspecific males more quickly than did males, and males responded more quickly to social odors of conspecific females than did females. There were no differences in the proportion of time males and females spent proximal to conspecific social odors. Males and females typically responded more quickly to and spent more tim.

Book Synopsis Ecology and Conservation of the Maned Wolf by : Adriana G. Consorte-McCrea
Download or read book Ecology and Conservation of the Maned Wolf written by Adriana G. Consorte-McCrea and published by CRC Press. This book was released on 2013-10-24 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wolves are controversial figures worldwide and much effort has focused on how to conserve them while addressing public concerns. With its solitary habits and fruit-eating diet, the endangered maned wolf roams the South American grasslands and swamps, playing a vital part in maintaining biodiversity hotspots. Compared to the grey wolf, little is known about its relationship with local people and the environment and the reasons for its decline, making research about this unique species an urgent concern. Ecology and Conservation of the Maned Wolf: Multidisciplinary Perspectives gathers the work of leading researchers from diverse disciplines and countries, covering up-to-date research on the biology, ecology, and conservation of the maned wolf. It presents innovative insights that can benefit conservation strategies and offers perspectives for the future of the species. The book is divided into three parts. Part I explains the general issues concerning the maned wolf: population viability, the relationship between maned wolves and people, and the management of captive maned wolves. It also reviews current aspects of species biology, including conservation genetics, feeding ecology, social structure and reproduction, and conservation medicine. Part II contains case studies that present knowledge gathered from conservation programs and field research in all countries where the species is currently found—Brazil, Uruguay, Argentina, Bolivia, and Paraguay. Part III offers perspectives from diverse fields of research, exploring the challenges and opportunities connecting maned wolf conservation efforts with those of its habitat and of other endangered species. This includes education and communication tools, the application of human dimensions research to maned wolf conservation, ethnoconservation perspectives, and the ecological and socioeconomic challenges to the conservation of the cerrado habitat.
Book Synopsis A Survey of the Red Wolf (Canis Rufus) by : Glynn A. Riley
Download or read book A Survey of the Red Wolf (Canis Rufus) written by Glynn A. Riley and published by . This book was released on 1972 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses the red wolf's (Canis rufus) status, distribution and ecology; and describes and differentiates the red wolf from the closely related canids. Difficulties in distinguishing red wolves from coyotes (Canis latrans) and red wolf-coyote hybrids have resulted in much confusion over the range and status of the red wolf.
Book Synopsis The Biology and Conservation of Wild Canids by : David W. Macdonald
Download or read book The Biology and Conservation of Wild Canids written by David W. Macdonald and published by OUP Oxford. This book was released on 2004-06-24 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: No group of wild mammals so universally captures the emotions of people world-wide than do wild canids. That emotion can be enchantment and fascination, but it can also be loathing, because the opportunism that is the hallmark of the dog family also leads them into conflict with humans. In the developed world at least, the fascination with wild canids doubtless stems from people's captivation with domestic dogs - everybody feels they are an expert on canids! While most people may be familiar with only the better known members of the dog family, such as the grey wolf and the red fox, there are in fact 36 species of wolves, dogs, jackals and foxes. They attract hugely disproportionate interest from academics, conservationists, veterinarians, wildlife managers and the general public. This book brings together in single volume an astonishing synthesis of research done in the last twenty years and is the first truly compendious synthesis on wild canids. Beginning with a complete account of all 36 canid species, there follow six review chapters that emphasise topics most relevant to canid conservation science, including evolution and systematics, behavioural ecology, population genetics, diseases, conflict/control of troublesome species, and conservation tools. Fifteen detailed case studies then delve deeply into the very best species investigations currently available written by all the leading figures in the field. Much of the material is previously unpublished and will make fascinating reading far beyond the confines of canid specialists. These chapters portray the unique attributes of wild canids, their fascinating (and conflictive) relationship with man, and suggestions for future research and conservation measures for the Canidae. While most canid species are widespread and thrive in human dominated landscapes, several are in severe jeopardy; habitat loss, illegal hunting, persecution by farmers and disease all imperil dwindling populations. A final chapter analyses the requirements of, and approaches to, practical conservation, with lessons that go far beyond the dog family. It concentrates particular attention on priorities for the protection of the most threatened canid species, including the red wolf, African wild dog, Ethiopian wolf, Island fox and Darwin's fox. The wild canids provide examples that will thrill the evolutionary biologists and theoretician, enthral the natural historian and challenge the conservationist and wildlife manager. Anybody interested in evolutionary and behavioural biology, in mammals, in the environment, or in conservation will find much that is new and enriching in this book.

Book Synopsis Reproductive Sciences in Animal Conservation by : William V. Holt
Download or read book Reproductive Sciences in Animal Conservation written by William V. Holt and published by Springer. This book was released on 2014-08-04 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproductive biology is more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species, technical developments have to be backed up by thorough biological understanding of the background behind the problems. This book is therefore threefold; (1) it provides a snapshot of the state of the art in terms of species-specific reproductive technologies, whether for individual animals or whole taxonomic groups; (2) it sets the reproductive problems in context and emphasizes the links between animal-based problems and the wider world, e.g. reproductive fitness and (3) it looks forward and presents realistic assessments of how effective some of the more recently developed techniques in reproductive technology might be at combating extinctions. This is a wide-ranging book that will be relevant to anyone involved in reproductive biology or in species conservation and provides provide them some useful perspectives about the real utility of current and emerging technologies. It has contributions from experts in reproduction and related fields.
