Book excerpt: O presente trabalho teve como objetivo avaliar os efeitos de quatro níveis de nitrogênio aplicados ao solo sobre o rendimento de grãos, componentes da produção e qualidade de grãos e sementes de três cultivares de arroz irrigado, plantados pelométodo de sementes pré-germinadas. O experimento foi instalado em 8 de dezembro de 1996, em solo de várzea irrigada por inundação da Estação Experimental de Agronomia do Instituto Agronômico, no município de Pindamonhangaba, São Paulo, latitude22ʻ55' sul, longitude 47ʻ27' oeste, e altitude de 560 m. Foram escolhidos os cultivares IAC 101, IAC 102 e IAC 242, submetidos à 0, 50, 100 e 150 kg de N/ha na forma de uréia, aplicados em três épocas: 113 no início do desenvolvimento dasplantas, 113 em pleno perfilhamento e 1/3 na formação do primórdio floral. Adotou-se esquema fatorial com 12 tratamentos em blocos ao acaso com 3 repetições. A fertilização nitrogenada influenciou positivamente a estatura das plantas, o número eo peso de grãos por panícula, o peso de 1000 grãos, as dimensões dos grãos, a produção de grãos e o rendimento de grãos inteiros no beneficiamento. O número de grãos granados por panícula foi o componente de produção que mais influenciou noaumento de rendimento de grãos. As maiores respostas à fertilização nitrogenada ocorreram entre os níveis O e 50 kg de N/ha, e para níveis acima de 100 kg de N/ha ocorreu redução de eficiência de utilização de N.O ciclo dos cult.

Book excerpt: Coasts and Estuaries: The Future provides valuable information on how we can protect and maintain natural ecological structures while also allowing estuaries to deliver services that produce societal goods and benefits. These issues are addressed through chapters detailing case studies from estuaries and coastal waters worldwide, presenting a full range of natural variability and human pressures. Following this, a series of chapters written by scientific leaders worldwide synthesizes the problems and offers solutions for specific issues graded within the framework of the socio-economic-environmental mosaic. These include fisheries, climate change, coastal megacities, evolving human-nature interactions, remediation measures, and integrated coastal management. The problems faced by half of the world living near coasts are truly a worldwide challenge as well as an opportunity for scientists to study commonalities and differences and provide solutions. This book is centered around the proposed DAPSI(W)R(M) framework, where drivers of basic human needs requires activities that each produce pressures. The pressures are mechanisms of state change on the natural system and Impacts on societal welfare (including well-being). These problems then require responses, which are the solutions relating to governance, socio-economic and cultural measures (Scharin et al 2016). - Covers estuaries and coastal seas worldwide, integrating their commonality, differences and solutions for sustainability - Includes global case studies from leading worldwide contributors, with accompanying boxes highlighting a synopsis about a particular estuary and coastal sea, making all information easy to find - Presents full color images to aid the reader in a better understanding of details of each case study - Provides a multi-disciplinary approach, linking biology, physics, climate and social sciences

Book excerpt: This book presents the main drivers of benthic structure and processes in estuaries from the 8,000 km-Brazilian coast, assesses the influence of natural and human disturbance, and discusses their ecological importance and management needs. Estuaries are unique coastal ecosystems often with low biodiversity that sustain and provide essential ecological services to mankind. These ecosystems include a variety of habitats with their own sediment and fauna dynamics, all of them globally altered or threatened by human activities. Mangroves, saltmarshes, tidal flats and other confined estuarine systems are under increasing stress by overfishing and other human activities leading to habitat and species loss. Combined changes in estuarine hydromorphology and in climate pose severe threats to estuarine ecosystems at a global scale.

Available in PDF, EPUB and Kindle. Book excerpt: Marine Bivalve Molluscs Marine Bivalve Molluscs is a comprehensive and thoroughly updated Second Edition of Bivalve Molluscs, covering all major aspects of this important class of invertebrates. As well as being an important class biologically and ecologically, many of the bivalves are fished and cultured commercially (e.g. mussels, oysters, scallops and clams) in a multi-billion dollar worldwide industry. Elizabeth Gosling has written a landmark book that will stand for many years as the standard work on the subject. Chapters in Marine Bivalve Molluscs cover morphology, ecology, feeding, reproduction, settlement and recruitment, growth, physiology, fisheries, aquaculture, genetics, diseases and parasites, and public health issues. A full understanding of many of these aspects is vital for all those working in bivalve fisheries and culture. An essential purchase for anyone concerned with this important class of animals, copies of Marine Bivalve Molluscs should be on the shelves of biologists, ecologists, environmental scientists, fisheries scientists and personnel within the aquaculture industry. Copies of the book should be available in all libraries and research establishments where these subjects are studied or taught. REVIEWS OF THE FIRST EDITION An admirable achievement...a valuable addition to marine sciences libraries everywhere. The back cover of this book says that it is a landmark text that will stand for many years as the standard work on this subject. I can only agree with this sentiment. ~ Aquaculture A welcome addition to the literature and provides the reader with a comprehensive overview of biological and environmental factors that affect and control both natural populations of marine bivalves and culture operations. ~ Aquaculture International The author has done an admirable job in compiling a wealth of information into a readable text. ~ Transactions of the American Fisheries Society Will serve well as a description of much of both the experimental biology and the aquaculture of bivalves. ~ Journal of Experimental Marine Biology and Ecology Provides excellent reviews of all major aspects...an extremely important reference for anyone engaged in bivalve research, fisheries management, and aquaculture. ~ Quarterly Review of Biology The book is very readable, in an easy style. It is well illustrated and there is a wealth of data and statistics presented. ~ Bulletin of the Malacological Society of London

This book was released on 2005-12-21 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: The initial plans for this book sprang from a late-afternoon conversation in a hotel bar. All three authors were attending the 1996 meeting of the Population As- ciation of America in New Orleans. While nursing drinks and expounding on a variety of topics, we began talking about our current research projects. It so happened that all three of us had been entertaining the notion of writing a book on state and local population projections. Recognizing the enormity of the project for a single author, we quickly decided to collaborate. Had we not decided to work together, it is unlikely that this book ever would have been written. The last comprehensive treatment of state and local population projections was Don Pittenger’s excellent work Projecting State and Local Populations (1976). Many changes affecting the production of population projections have occurred since that time. Technological changes have led to vast increases in computing power, new data sources, the development of GIS, and the creation of the Internet. The procedures for applying a number of projection methods have changed considerably, and several completely new methods have been developed.
