Download or read book The Sparrows written by Denis Summers-Smith and published by A&C Black. This book was released on 2010-11-30 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: While Denis Summers-Smith's monograph The Sparrows presented his knowledge of sparrow biology, this volume tells the other, human, side of the tale. Denis Summers-Smith first took up the study of the House Sparrow in 1947, thinking that the difficulties of travel in post-war Britain would best suit the study of a species always close at hand. The humble House Sparrow, common everywhere, was surprisingly poorly researched and his work soon provided interesting insights into this successful and adaptable little bird. As new opportunities to travel opened up, his interest blossomed to take in the genus Passer as a whole. His travels would ultimately lead to his study of all but one of the group, found only in deepest Turkestan, and to the publication of his authoritative monograph on sparrows in 1988. His wry descriptions of the tribulations and unexpected pleasures of a traveller on four continents, from the Himalayas and Thailand to Africa and the Americas (with a good few islands in between), are interspersed with observations and speculations on the biology of sparrows in a wide variety of habitats. Everywhere local officials and bird watchers warmed to the eccentric Scot in pursuit of the little birds that nobody notices but which so often make their homes beside us. The author's own photographs and delightful cartoons by Euan Dunn further paint the picture of this lifelong search.

Available in PDF, EPUB and Kindle. Book excerpt: In 1977, the Volkswagen Foundation sponsored the first of a series of International Symposia on Fire Ecology at Freiburg University, Federal Republic of Germany. The scope of the congresses was to create a platform for researchers at a time when the science of fire ecology was not yet recognized and established outside of North America and Australia. Whereas comprehensive information on the fire ecology of the northern boreal, the temperate, and the mediter ranean biotas is meanwhile available, it was recognized that conside rable gaps in information exist on the role of fire in tropical und sub tropical ecosystems. Thus it seemed timely to meet the growing scientific interest and public demand for reliable and updated infor mation and to synthesize the available knowledge of tropical fire ecology and the impact of tropical biomass burning on global eco system processes. The Third Symposium on Fire Ecology, again sponsored by the Volkswagen Foundation and held at Freiburg University in May 1989, was convened to prepare this first pantropical and multidisci plinary monograph on fire ecology!. The book, in which 46 scientists cooperated, analyzes those fire-related ecosystem processes which have not yet been described in a synoptic way. Following the editor's concept, duplication at previous efforts in describing tropical vegeta tion patterns and dynamics was avoided. Extensive bibliographical sources are given in the reference lists of the chapters.

Available in PDF, EPUB and Kindle. Book excerpt: The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind. Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification is a grave concern. These zones are harsh habitats for humans. The famines that resulted from drought during the late 1960's and the 1970's in the African Sahel illustrated the unreliability of present agricultural systems in this zone. Large fluctuations in ag ricultural production have occurred in semi-arid zones of Australia, North Ameri ca, and the Soviet Union due to periodic droughts, even though considerable ag ricultural technology has been devoted to agricultural development in these zones. The challenge to mankind is to manage these different semi-arid zones so that pro ductivity is increased and stabilized, and environmental deterioration is decreased. Irrigation can be used to increase and stabilize agricultural production in semi-arid zones as discussed in Volume 5 of this series, Arid Zone Irrigation. The present volume, Agriculture in Semi-Arid Environments, focuses on dryland farming in semi-arid zones, and is relevant to the large areas of the world where rainfall is limiting and where water is not available for irrigation. This volume is designed to assist agricultural development in these areas and consists of reviews and analyses of available information by scientists working in Africa, Australia, and at the U ni versity of California.
