The Living Deserts of Southern Africa


Book Description

Where rainfall is meagre and unpredictable, temperatures fluctuate between extreme hot and cold, and food is scarce, it seems that little can survive.




The Living Deserts of Southern African


Book Description

For generations, the deserts of southern Africa have intrigued scientists and travellers alike. Seemingly barren wastes, they in fact teem with life – from ants to elephants, stone plants to the curious welwitschia, dainty dik-diks to towering gemsbok, and cart-wheeling spiders to fog-basking beetles. How do they cope with scarce resources, unpredictable rainfall and extreme temperatures? How do they protect themselves against predators? And what is the impact of climate change on these life forms and their habitats? Drawing on an earlier edition, published in 1993, biologist Barry Lovegrove answers these questions and unravels many of the mysteries associated with life in the desert. He describes the four arid biomes of South Africa, Namibia and Botswana – Desert, Arid Savanna, Succulent Karoo and Nama-Karoo – and explains how and why such a great diversity of plants, insects, mammals, reptiles and birds successfully exist in these regions. The text is supported by the most recent research, spectacular photographs, and explanatory diagrams and maps. The Living Deserts of Southern Africa is a compelling, in-depth read that is accessible to both the serious student and academic as well as the interested nature lover. Sales points: A fully revised and updated edition of a classic text (1993) on southern Africa’s desert zones; highly readable, entertaining and informative that draws on the latest scientific research; covers the desert regions of South Africa, Namibia and Botswana; stunning full-colour photographs support the text.










Get Bushwise: On Safari. Desert. River. Bushveld


Book Description

This bumper edition, comprising three lively children’s nature guides, brings together a treasure trove of information, colourful images, games and activities for young readers. A local guide leads adventurers on safaris into three surprisingly varied worlds: the bushveld, a river and a desert. Each environment brings its unique flavour to the adventure; multiple images (both photos and illustrations) and interesting habits and lifestyles. Readers are encouraged to play along by means of engaging activities, games and quizzes, with answers at the end of each section. Nature’s edible treats and useful props are introduced, along with survival techniques for the young explorer. This volume illuminates three important southern African natural arenas, and will engage readers from cover to cover.




Ecophysiology of Desert Birds


Book Description

In the Preface to his volume on Ecophysiology of the Camelidae and Desert Ruminants in this series, Trevor Wilson mentions his hesitation at the invitation from John Cloudsley-Thompson to write the book, because he had been out of direct touch with desert biology for some years. My response to John's invitation to write Ecophysiology of Desert Birds was much the same, and for the same reasons. However, with his encouragement and, taking account of the fact that a colleague of mine who is much better suited to do the job had turned it down because of pressure of work, I accepted the challenge and have enjoyed it immensely. It has been my privilege to spend much time in the deserts of North and South America, southern Africa and Australia, some of it with my wife, Cherie, whose editing of the entire text has improved the work immeasurably. Indeed, I believe it would have been proper for her to accept coauthorship, but she graciously declined the offer! I owe her a debt of gratitude which I hope will be repaid in part by her seeing the text finally between covers. The chapters on water regulation (Chap. 5) and thermo regulation (Chap. 6) have benefited from the refereeing of my colleague, Dr. Barry Lovegrove, of the Department of Zoology and Entomology, University of Natal, Pietermaritzburg.




Fires of Life


Book Description

A groundbreaking argument on how endothermy--arguably the most important innovation in vertebrate evolution--developed in birds and mammals "Vividly narrated and illustrated. . . . Provocative and fascinating for specialists and lay readers alike."--Southeastern Naturalist This pioneering work investigates why endothermy, or "warm-bloodedness," evolved in birds and mammals, despite its enormous energetic costs. Arguing that single-cause hypotheses to explain the origins of endothermy have stalled research since the 1970s, Barry Gordon Lovegrove advances a novel conceptual framework that considers multiple potential causes and integrates data from the southern as well as the northern hemisphere. Drawing on paleontological data; research on extant species in places like the Karoo, Namaqualand, Madagascar, and Borneo; and novel physiological models, Lovegrove builds a compelling new explanation for the evolution of endothermy. Vividly narrated and illustrated, this book stages a groundbreaking argument that should prove provocative and fascinating for specialists and lay readers alike.




Encyclopedia of Deserts


Book Description

Encyclopedia of Deserts represents a milestone: it is the first comprehensive reference to the first comprehensive reference to deserts and semideserts of the world. Approximately seven hundred entries treat subjects ranging from desert survival to the way deserts are formed. Topics include biology (birds, mammals, reptiles, amphibians, fishes, invertebrates, plants, bacteria, physiology, evolution), geography, climatology, geology, hydrology, anthropology, and history. The thirty-seven contributors, including volume editor Michael A. Mares, have had extensive careers in deserts research, encompassing all of the world’s arid and semiarid regions. The Encyclopedia opens with a subject list by topic, an organizational guide that helps the reader grasp interrelationships and complexities in desert systems. Each entry concludes with cross-references to other entries in the volume, inviting the reader to embark on a personal expedition into fascinating, previously unknown terrain. In addition a list of important readings facilitates in-depth study of each topic. An exhaustive index permits quick access to places, topics, and taxonomic listings of all plants and animals discussed. More than one hundred photographs, drawings, and maps enhance our appreciation of the remarkable life, landforms, history, and challenges of the world’s arid land.




In Search of the African Lion


Book Description

The African lion (Panthera leo), long celebrated as the king of beasts, faces unprecedented challenges in the wild today. Loss of habitat through the expansion of human activity increasingly restricts the lion to game reserves and national parks, while diseases such as bovine tuberculosis pose a threat to the health of lion prides. Over a period of two years, Roger and Pat de la Harpe have documented wild lions of South Africa, and the result is a superbly photographed and engagingly written tribute to this often misunderstood predator. In Search of the African Lion enters the complex world of the lion, describing pride dynamics, hunting patterns, the reproductive cycle and interactions with human communities. The book focuses on four main areas: the Kalahari, the Madikwe/Mapungubwe area, the Greater Kruger National Park and Northern Zululand -each with its own problems, challenges and opportunities. In addition, the authors highlight the important work done by game rangers, wildlife managers and scientific researchers in understanding the lion and in protecting existing populations. The In Search of... series focuses on the plight of threatened and endangered species. Also available by the same authors: In Search of the African Wild Dog.




Grasses & Grazers of Botswana and the surrounding savanna


Book Description

An accessible reference to the grasses and grazers of this region, Veronica Roodt’s book details the fascinating ways in which these plants and animals have evolved together. The book covers: some 100 grass species (includes sketches and photographs of each species) that are preferred livestock and wild game fodder and that serve as indicators of veld condition; the role of grasses in the food chain; grass anatomy and growth; how grazers have evolved to survive on grasses, both physically and in terms of their behaviour; significant grazers that occur in the region and that play a vital role in shaping the savanna biome, and effective grassland management practices. Nature lovers, farmers, students and tourists who seek an in-depth look at the interactions between grasses and the grazers that depend on them for life need look no further than this invaluable guide.
