Download or read book Manejo de Pastos y Forrajes Tropicales written by Ali Perozo and published by Ali David Perozo Bravo. This book was released on 2013-11-28 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: La alimentación de los rebaños en el trópico se fundamenta en el uso de pastos y forrajes, los cuales constituyen la dieta básica y más económica en la alimentación de rumiantes (bovinos, bufalinos, caprinos y ovinos). Sin embargo, la producción de materia seca de los pastos y forrajes a través del año es irregular en cantidad y calidad debido a limitaciones climáticas y edáficas. Los pastos son importantes en principio porque pueden crecer en condiciones marginales donde otros cultivos no pueden, lo cual se atribuye a su mayor eficiencia en el uso del agua y a un máximo aprovechamiento de los nutrientes del suelo; además, los pastos proporcionan materia orgánica al suelo, lo que ayuda en su conservación. Existe toda una gama de estrategias que pueden utilizarse para iniciar y mejorar el cultivo de las tierras, la cuales serán detalladas a lo largo del contenido del Cuaderno Científico 13 editado por la Fundación Girarz. La difusión de este Cuaderno se realizó en la LXIII Reunión dedicada al “Curso de Manejo de Pastos y Forrajes Tropicales” en celebración del XXXV Aniversario de la Fundación GIRARZ y como homenaje al 54 Aniversario de la creación de la Facultad de Agronomía de la Universidad del Zulia, en el estado Zulia

Available in PDF, EPUB and Kindle. Book excerpt: The central aim of this publication is to consider the key elements of a modern, comprehensive, and effective legal framework for successful management of protected areas. They provide practical guidance for all those involved in developing, improving, or reviewing national legislation on protected areas, be they legal drafters and practitioners, protected area managers, interested NGOs, or scholars. These guidelines include fifteen case studies, eight dealing with the protected area legislation of individual countries and six cases dealing with specific sites providing fundamental solutions that stand the test of time.
Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Download or read book Lake Titicaca written by C. Dejoux and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Titicaca, because of its area and volume and its situation at high attitude within the tropics, is a unique hydrological site in the world. It should be noted that it stands at the transition point between two very distinct geographical regions: the desert fringe of the Pacific coast to the west and the great Amazonian forest extending to the Atlantic coast to the east. Many scientists have been attracted to the lake in the past because of its unusual limnological features. In this book the editors have compiled an exhaustive review of current knowledge from the existing literature and from the results of more recent observations. It is certain that this book will become the essential reference work for scientists wanting to make progress in revealing the lake's secrets. It can be stated unequivocally that this work constitutes a complete review of the present state of knowledge on Lake Titicaca and that it provides the latest results of research on this habitat.
Download or read book Banana Genomics and Transgenic Approaches for Genetic Improvement written by Sukhada Mohandas and published by Springer. This book was released on 2016-09-08 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bananas and plantains are among the most important food and cash crops in the world. They are cultivated in more than 135 countries, across the tropics and subtropics, with an annual global production of ca. 130 million metric tonnes. Though bananas are one of the most important components of food security in many developing countries, banana production is threatened by both abiotic and biotic stresses. These include a wide range of diseases and pests, such as bunchy top virus, burrowing nematodes, black Sigatoka or black leaf streak, Fusarium wilt, etc. In recent years, considerable progress has been made and several biotechnological and genomic tools have been employed to help understand and unravel the mysterious banana genome. Molecular and genomic studies have helped to decipher the Musa genome and its evolution. Genetic linkage map and whole genome sequencing of both Musa acuminata and Musa balbisiana (progenitors of cultivated banana) have completely changed the way of thinking and the approach on banana crop improvement. Whole-genome sequencing has helped to improve the selection of quantitative traits such as yield, as well as the selection of optimal parents for developing required hybrids in breeding programs. Gene isolation and the analysis of mutants have helped in the characterization of genes of agronomic value and the associated regulatory sequences. With the advent of molecular markers and new statistical tools, it is now possible to measure the diversity, identify genes and useful alleles linked to important agronomic traits. Further these alleles can be incorporated into cultivars through marker assisted selection or through transgenic approach. Transgenic approaches are potential tools for direct transfer of these genes into popular cultivars, which are generally not amenable for conventional breeding techniques, in specific with crops such as bananas which are sterile, triploid and heterozygous thereby making it difficult to reconstruct the recurrent genotypes in banana. Transgenic techniques thus have helped overcome the difficulty of working with sterile, triploid banana crop. In the last five years, enormous amount of new information and techniques have been generated for banana. A comprehensive book entitled “Banana: Genomics and Transgenic Approaches for Genetic improvement” on banana genomics, latest transgenic technologies and tools available for improved crop development in banana will address all these requirements.

Download or read book The Vicu a written by Iain Gordon and published by Springer. This book was released on 2008-10-23 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Things have changed. In 1969 when the Convention for the Conservation of the Vicuña was drafted, in an attempt to save the vicuña from its tumbling decline towards extinction, both the science and the philosophy of wildlife conservation were radically different. It is thus a tribute to the prescience of those involved at the time that the rescue plan had, even through the harsh lens of hindsight, a d- tinctly Twenty First Century flavour. After all, it was predicated on the expectation that if vicuña could be saved, they would one day become a valued asset, generating revenue for the human communities that fostered their survival. Embodied in this aspiration are the main structures of modern biodiversity conservation – not only is it to be underpinned by science, but that science should be of both the natural and the social genres, woven into inter-disciplinarity, and thereby taking heed of e- nomics, governance, ownership and the like, alongside biology. In addition, it should include, as a major strut, the human dimension, taking account of the affected constituencies with their varied stakes in alternative outcomes. This c- temporary framework for thinking about biodiversity conservation is inseparable from such wider, and inherently political, notions as community-based conser- tion and ultimately sustainable use.
