Meiosis
Meiosis, the process of forming gametes in preparation for sexual reproduction, has long been a focus of intense study. Meiosis has been studied at the cytological, genetic, molecular and cellular levels. Studies in model systems have revealed common underlying mechanisms while in parallel, studies in diverse organisms have revealed the incredible variation in meiotic mechanisms. This book brings together many of the diverse strands of investigation into this fascinating and challenging field of biology.
Brazilian Crops in the Global Market
This book comprehensively examines the development of Brazilian agriculture by focusing on the crops which evolved from national products to international commodities on a massive scale. It traces the transformation of Brazil from a country with low-yield levels in 1950 to its current position as a leading world producer. The first section of the book examines the modernization of Brazilian agriculture through a government programme which transformed traditional agriculture through subsidized credit, guaranteed prices, stock purchases, land utilization laws, modern research, new technology and major support for exports. It also explores the changing structures of agricultural production and ...
Genetic Resources, Chromosome Engineering, and Crop Improvement:
In recent decades, livestock producers have moved away from open grazing for a number of reasons, none having to do with the health of consumers. Genetic Resources, Chromosome Engineering, and Crop Improvement: Forage Crops demonstrates how state-of-the-art technology can encourage the raising of livestock in open pastures where they can be fed gra

Cultures fourragères tropicales
A l'interface entre culture et élevage, les plantes fourragères occupent une place bien particulière dans les systèmes de production. Le Cirad, l'Inra et l'Ird ont rassemblé ici le fruit de 30 années d'expérimentations en Afrique de l'Ouest, aux Antilles, à la Réunion, dans les territoires français du Pacifique et à Madagascar. Cet ouvrage apporte des connaissances de base utiles à l'élaboration des techniques de culture et d'exploitation, fournit au lecteur des méthodes pour accéder à l'observation et à l'expérimentation. Il présente des connaissances récentes dans des domaines en pleine évolution comme l'écophysiologie ou la génétique des graminées, et des aspects plus techniques destinés à aider l'éleveur dans ses choix.
