The immense desert areas of Australia used to be called its 'dead heart'. Today we realise that deserts and savannahs have complex ecosystems, with plants and animals that have adaptations enabling them to survive there and not in any other location. Deserts are now iconic symbols of Australia and are no longer dismissed as useless, empty wastelands. Although colonial explorers found the deserts harsh and unforgiving, Indigenous Australians learned how to live in the deserts, find water and prosper. Learn about each of Australia's ten largest deserts and also find out why the Nullarbor Plain is different from all of them.

Download The Biology of African Savannahs Book in PDF, ePub and Kindle
Savannah habitats comprise an ecologically important, but ultimately fragile, ecosystem. They constitute one of the largest biomes on Earth, covering almost 20% of the land surface, and can be simply described as tropical and subtropical grasslands with scattered bushes and trees. Most savannahs occur in Africa, although smaller areas can be found in South America, India, and Australia. They form a rich mosaic of diverse ecosystems, and this book offers a concise but comprehensive introduction to their ecology, biodiversity, and conservation. The Biology of African Savannahs describes the major plants (grasses, and trees such as Acacia) and animals (mainly large mammals) that live in this habitat, and examines the biological and ecological factors that influence their population size, interactions (such as predation), and community composition. Conservation issues such as climate change, hunting, and conflict between wildlife and domestic animals are also discussed. This new edition has been updated throughout with the latest research in the field, and contains new technique boxes which introduce readers to some of the analytical methods used to study African savannahs. This accessible text is suitable for both senior undergraduate and graduate students taking courses in savannah and tropical ecology as part of a wider ecology and/or conservation biology degree programme. It will also be of relevance and use to the many professional ecologists and conservation practitioners requiring a concise but authoritative overview of the topic.

Download The Dark Side of the Hive Book in PDF, ePub and Kindle
Honey bees have been described as exceptionally clever, well-organized, mutualistic, collaborative, busy, efficient--in short a perfect society. While the colony is indeed a marvel of harmonious, efficient organization, it also has a considerable dark side. Authors Robin Moritz and Robin Crewe write about the life history of the honey bee, Apis mellifera, highlighting conflict rather than harmony, failure rather than success, from the perspective of the individual worker in the colony. When one looks carefully, the honey bee colony is far from being perfect. As with any complex social system, honeybee societies are prone to error, robbery, cheating, and social parasitism. Nevertheless, the hive gets by remarkably well in spite of many seemingly odd biological features. The perfection that is perceived to exist in the honeybee's social organization is the function of a focus on the colony as a whole rather than exploring the idiosyncrasies of its individual members. The Dark Side of the Hive thus focuses on the role of the individual rather than that of the collective. Moritz and Crewe dissect the various careers that individual male and female honey bees can take and their role in colony organization. Competition between individuals using both physical and chemical force drives colonial organization. This book deals with individual mistakes, maladaptations and evolutionary dead-ends that are also part of the bees' life. The story told about these dark sides of the colony spans the full range of biological disciplines ranging from genomics to systems biology.

Download The History of the Peoples of the Eastern Desert Book in PDF, ePub and Kindle
The last quarter century has seen extensive research on the ports of the Red Sea coast of Egypt, the road systems connecting them to the Nile, and the mines and quarries in the region. Missing has been a systematic study of the peoples of the Eastern Desert--the area between the Red Sea and the Nile Valley--in whose territories these ports, roads, mines, and quarries were located. The historical overview of the Eastern Desert in the shape of a roughly chronological narrative presented in this book fills that gap. The multidisciplinary perspective focuses on the long-term history of the region. The extensive range of topics addressed includes specific historical periods, natural resources, nomadic survival strategies, ancient textual data, and the interaction between Christian hermits and their neighbors. The breadth of perspective does not sacrifice depth, for all authors deal in some detail with the specifics of their subject matter. As a whole, this collection provides an outline of the history and sociology of the Eastern Desert unparalleled in any language for its comprehensiveness. As such, it will be the essential starting point for future research on the Eastern Desert. Includes a CD of eleven audio files with music of the Ababda Nomads, and six short videos of Ababda culture.
