Available in PDF, EPUB and Kindle. Book excerpt: This is a revised edition of a widely praised guide to the birds of the largest of the Caribbean islands and the neighboring Virgin Islands. It includes detailed accounts of all 284 well-documented species known to occur in the region, 273 being illustrated. The book also contains specific sections entitled "Biogeography" and "Conservation" to foster an appreciation of the uniqueness of the region's wildlife and to develop an awareness of local conservation issues. The section "Places to Bird" will help make the stay of short-term visitors more productive. The book also substantially updates the data on avian distribution and abundance in the region covering records through November 1988. From reviews of the first edition: "This well-illustrated volume is a must for any student of birds visiting Puerto Rico or the Virgin Islands."--Chandler S. Robbins, The Quarterly Review of Biology "A valuable and informative guide."--James A. Dick, The Wilson Bulletin "This well-written book is the first comprehensive guide to the birds of Puerto Rico and the Virgin Islands. All species, including winter visitors (which comprise 47 percent of the avifauna) are described and illustrated, making a second volume for identification of North American migrants unnecessary. . . . Aside from being a fine field guide, the book contains useful summaries of the biogeography of the region and the ecology of avian populations. . . . A major contribution is Raffaele's presentation of a wealth of hitherto unpublished information on the natural history of the region's birds."--James W. Wiley, Ibis

Book Synopsis Agricultural Ecology and Environment by : B.R. Stinner
Download or read book Agricultural Ecology and Environment written by B.R. Stinner and published by Elsevier. This book was released on 2012-12-02 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability.The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.
