This book was released on 1982 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: A principal causa do baixo desempenho do rebanho bovino na região dos Cerrados e a falta de alimentação adequada em qualidade e quantidade durante o período seco do ano, que dura de quatro a seis meses (maio-outubro). Nesse período, as pastagens nativas e pastagens cultivadas de gramíneas perdem muito do seu valor nutricional. Em situações climáticas semelhantes a dos Cerrados; em outros países tropicais, a inclusão de uma leguminosa nas pastagens nativas ou a formação de pastagens consorciadas de gramíneas e leguminosa permitiram uma melhor acentuada na performance animal. Diversas tentativas do uso de leguminosas forrageiras, ou em pastagens nativa, tiveram pouco sucesso na região dos Cerrados. Isso, deveu-se principalmente a pouca adaptação das leguminosas.usadas, a maioria delas cultivares comerciais australianas e, portanto, selecionadas para as condições da Austrália. Por exigirem solos ferteis, a implantação de tais cultivares (como o siratro e a soja perene) nos solos pobres como os dos Cerrados necessita de grandes investimentos em adubação. Outra desvantagem e sua suscetibilidade a doenças, como a antracnose em Stylosanthes spp., por exemplo. Assim, tornou-se uma prática normal na região a formação de pastagens puras de gramíneas. Essas pastagens permitem um aumento sensível na capacidade de suporte das fazendas nos primeiros anos, mas não resolvem os problemas de perda de peso dos animais no período seco. Em poucos anos, sua produção e reduzida pela deficiência de nitrogênio no sistema solo-planta......

Download or read book The Cerrados of Brazil written by Paulo S. and published by Columbia University Press. This book was released on 2013-02-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Download or read book The Biogeochemistry of the Amazon Basin written by Michael E. McClain and published by Oxford University Press. This book was released on 2001-11-08 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a complex assemblage of largely intact ecosystems that support the earth's greatest diversity of life, the Amazon basin is a focal point of international scientific interest. And, as development and colonization schemes transform the landscape in increasing measure, scientists from around the world are directing attention to questions of regional and global significance. Some of these qustions are: What are the fluxes of greenhouse gases across the atmospheric interface of ecosystems? How mush carbon is stored in the biomass and soils of the basin? How are elements from the land transferred to the basin's surface waters? What is the sum of elements transferred from land to ocean, and what is its marine "fate"? This book of original chapters by experts in chemical and biological oceanography, tropical agronomy and biology, and the atmospheric sciences will address these and other important questions, with the aim of synthesizing the current knowledge of biochemical processes operating within and between the various ecosystems in the Amazon basin.

Download or read book Tropical Rain Forests written by Richard T. Corlett and published by John Wiley & Sons. This book was released on 2011-03-03 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of Tropical Rain Forests: an Ecological and Biogeographical Comparison exploded the myth of ‘the rain forest’ as a single, uniform entity. In reality, the major tropical rain forest regions, in tropical America, Africa, Southeast Asia, Madagascar, and New Guinea, have as many differences as similarities, as a result of their isolation from each other during the evolution of their floras and faunas. This new edition reinforces this message with new examples from recent and on-going research. After an introduction to the environments and geological histories of the major rain forest regions, subsequent chapters focus on plants, primates, carnivores and plant-eaters, birds, fruit bats and gliding animals, and insects, with an emphasis on the ecological and biogeographical differences between regions. This is followed by a new chapter on the unique tropical rain forests of oceanic islands. The final chapter, which has been completely rewritten, deals with the impacts of people on tropical rain forests and discusses possible conservation strategies that take into account the differences highlighted in the previous chapters. This exciting and very readable book, illustrated throughout with color photographs, will be invaluable reading for undergraduate students in a wide range of courses as well as an authoritative reference for graduate and professional ecologists, conservationists, and interested amateurs.
