This groundbreaking book fills a large hole in the literature for one of the most diverse and least known areas of Africa. Ethiopia and Eritrea have a fascinating and unique avifauna. Poorly known in comparison to many parts of Africa, knowledge on bird distribution in the two countries is scattered throughout the literature. For more than 35 years, the authors have been painstakingly collecting bird records in the region and plotting them on half-degree maps, including published records, data from museum specimens, sightings from their own extensive travels and, more recently, records from the many birdwatchers that now visit Ethiopia. The resulting atlas provides, for the first time, an accurate assessment of the distribution of each of the 870 species known from the two countries, including valuable information on breeding. The succinct text summarises the results and discusses distribution to subspecies level. Extensive introductory chapters cover topics such as topography, geology, vegetation, climate, habitats, conservation, migration, breeding seasons, bird ringing, and the history of ornithology in the region.

Community seed banks first appeared towards the end of the 1980s, established with the support of international and national non-governmental organizations. This book is the first to provide a global review of their development and includes a wide range of case studies. Countries that pioneered various types of community seed banks include Bangladesh, Brazil, Ethiopia, India, Nepal, Nicaragua, the Philippines and Zimbabwe. In the North, a particular type of community seed bank emerged known as a seed-savers network. Such networks were first established in Australia, Canada, the UK and the USA before spreading to other countries. Over time, the number and diversity of seed banks has grown. In Nepal, for example, there are now more than 100 self-described community seed banks whose functions range from pure conservation to commercial seed production. In Brazil, community seed banks operate in various regions of the country. Surprisingly, despite 25 years of history and the rapid growth in number, organizational diversity and geographical coverage of community seed banks, recognition of their roles and contributions has remained scanty. The book reviews their history, evolution, experiences, successes and failures (and reasons why), challenges and prospects. It fills a significant gap in the literature on agricultural biodiversity and conservation, and their contribution to food sovereignty and security.

The germination of seeds is a magical event, in which a pinch of dust-like material may give rise to all the power and the beauty of the growing plant. The mechanisms of seed dormancy, of the breaking of seed dormancy and of germination itself continue to remain shrouded in mystery, despite the best efforts of plant scientists. Perhaps we are getting there, but very slowly. This book considers germination and dormancy from the point of view of plant physiology. Plant physiologists attempt to understand the relation ship between plant form and function and to explain, in physical and chemical terms, plant growth and development. The place of germination and dormancy in plant ecophysiology is taken into account with attempts to understand the seed in its 'environment, whether the environment be natural, semi-natural or wholly artificial. In due course plant scientists hope to develop a precise understanding of germination and dormancy in cellular and molecular terms, and therefore there is some biochemistry in this book. Biochemists who wish to learn something about seeds should find this book useful.
