"Find out about camels and scorpions in the desert. View lions, elephants, and other animals of the grasslands. Discover animals that live in different layers of a rain forest. Three special habitats of Africa are waiting for you!"--Page 4 of cover
"Raven's 8th edition of Environment offers more detailed content than the Visualizing text for a better understanding and integration of the core environmental systems and to view and analyze the role those systems play. Shorter, but still comprehensive coverage focuses on ethical decision making and key local environmental science issues, requiring readers to think critically about the course material outside of the classroom. Other features include brief text in the comprehensive segment; extensive chapter pedagogy to help reinforce the systems approach; more opportunities to think critically about the how systems intersect and fit together; and new data interpretation questions at the end of each chapter"--
Bridge Over Troubled American Waters (Based On Race Divisions in America) African - Americans have advanced individually but as a unit, we have utterly failed. Our doctrine should be not to harvest one person or outside race with leadership. It is said that it is impossible for African - Americans to come together as "one" because of our mixed breeding with other races which has left us without a race identity. There are many people who are not enjoying the pinnacles of success in America. They have been heard to say that America does not practice what it preaches pertaining to articles found in the constitution denoting to the rights of all Americans.
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.
Twenty-six papers form a summary of research on glacial history, paleoclimatology, biogeography, ecosystem disequilibrium. Focus is on detailed chrono-stratigraphic, glacial geologic, and vertebrate paleontologic problems.
This is the only comprehensive account of all eight species in the genus Adansonia. It describes the historical background from the late Roman period to the present. It covers the extraordinary variety of economic uses of baobabs. There are also appendices on vernacular names, gazetteer, economics, nutrition and forest mensuration. This book fills a gap in the botanical literature. It deals with a genus that has fascinated and intrigued scientists and lay persons for centuries.
For the first two thirds of our evolutionary history, we hominins were restricted to Africa. Dating from about two million years ago, hominin fossils first appear in Eurasia. This volume addresses many of the issues surrounding this initial hominin intercontinental dispersal. Why did hominins first leave Africa in the early Pleistocene and not earlier? What do we know about the adaptations of the hominins that dispersed - their diet, locomotor abilities, cultural abilities? Was there a single dispersal event or several? Was the hominin dispersal part of a broader faunal expansion of African mammals northward? What route or routes did dispersing populations take?
It may well be said that there can be no geography which concerns itself with the actual shape and form of the land surface, solid rode, the configuration and extent of the seas and oceans, the enveloping atmosphere without which life as we know it cannot exist, the physical process which take place in that atmosphere. This book has been designed to cover the syllabus of physical geography required for the B.A. students of the Indian Universities. The subject matter has been arranged so as to provide clear and integrated approach to the subject with all essential tools of applicable geography for B.A. curriculum. Contents: Biogeography, Ecosystem, Biosphere, Biome, Food Chain.
