Book Description
Principles and Standards for Measuring Net Primary Production in Long-Term Ecological Studies is the first book to establish a standardized method for measuring net primary productivity (NPP) in ecological research. Primary productivity is the rate at which energy is stored in the organic matter of plants per unit area of the earth's surface. As the beginning stage of the carbon cycle, our ability to accurately measure NPP is essential to any ecological analysis, as well as agronomy, forestry, fisheries, limnology and oceanography. In fact, NPP measurements are fundamental to ecosystem studies at thousands of sites around the world. All 26 LTER sites will be expected to collect and report data using these new standards, but the standards should reach well beyond LTER sites. Identified standards for NPP measurements will allow researchers from diverse biomes to authoritatively compare measurements among their sites. Comparable measurements will build a foundation for a broad scale understanding of the environmental, biological, and nutrition controls on NPP. The book includes chapters for each of the critical biome types, including special techniques that work best in each environment. For example, there are chapters that discuss grassland ecosystems, urban ecosystems, marine pelagic ecosystems, forest ecosystems, and salt marsh ecosystems, among others.

Book Description
The Amazon Basin contains the largest and most diverse tropical rainforest in the world. Besides the Andes and the Atlantic Ocean, the rainforest is bounded to the north by the Guiana crystalline shield and to the south by the Brazilian crystalline shield, marked at their edges by cataracts in the rivers and often dominated by grasslands. This book is motivated not just by the Amazon's scientific interest but also by its role in many ecosystem functions critical to life on Earth. These ecosystems are characterized both by their complexity and their interactive, higher-order linkages among both abiotic and biotic components. Within Amazonia, the Western Amazon (west of 65° latitude) is the most pristine and, perhaps, the most complex within the Amazon Basin. This Western Amazon may be broadly divided into non-flooded forests (e.g. terra firme, white sand, palm) and forests flooded with white water (generally referred to as várzea) and with black water (generally referred to as igapó). Here, for the first time, is a book devoted entirely to Western Amazonia, containing chapters by scientists at the forefront of their own areas of expertise. It should be a valuable resource for all future researchers and scholars who venture into Western Amazonia, as it continues to be one of the most beautiful, mysterious, remote and important ecosystems on Earth.

Book Description
This book is a product of Brazilian Academy of Sciences Study Group about water issue. The water cycle was addressed based on an integrated point of view, aiming at joining technological and ecological solutions and integrating quantitative and qualitative aspects of this important environmental asset. Issues such as the water resources management and irrigated agriculture, water and health, water and economy, conservation and reuse as management tools, water in the Brazilian semi arid, water in Amazon, urbanization and water resources, education for the sustainability of water resources, groundwater, availability, pollution and eutrophication of water and science, technology and innovation are of the utmost importance for this exact moment in Brazil, and particularly to the State of Sao Paulo. Addressing these issues will undoubtedly contribute towards a sustainable management of water resources trough the coordinated work of different fields of science, progressing a systemic view about water, that would then finally allow management professionals the possibility of an integral action in anticipating problems and thus anticipate solutions.

Book Description
Savannas are the most widespread ecosystem in the tropics and as such are subjected to great human pressure that may result in massive soil degradation. The book addresses the role of species in the function of savanna ecosystems. It is shown that savannas are enormously diverse and that four factors determine the function of savanna ecosystems: Plant Available Moisture; Plant Available Nutrients; Fire; Herbivores.

Book Description
Many policy makers in East Africa have preconceptions about the value of pastoralism as a land-use system believing it to be economically inefficient and environmentally destructive. Yet, this is not evidence-based. Not only is there no consensus on what is a dynamic economic model of pastoralism, no mechanisms exist to inform government decision-making of its comparative advantages over alternative land uses. This paper argues that pastoralism does make a significant contribution to society and that, with better understanding, planning and data collection, its value can be demonstrated. The paper presents a preliminary framework for assessing the benefits of pastoralism that goes beyond conventional criteria relating to livestock and their by-products. While the paper focuses on East Africa, much of the analysis is applicable to pastoral systems in other regions of Africa.

Book Description
Volume 74 contains six excellent cutting-edge reviews detailing advances in the plant and environmental soil sciences. Chapter 1 is an extensive review on soil quality. Chapter 2 covers recent advances in understanding the formation of metal hydroxide precipitates on soil surfaces and their implications on metal sequestration and soil remediation. Chapter 3 is a timely review on effects of organic acid exudation from roots on phosphorus uptake and aluminum tolerance of plants in acid soils. Chapter 4 discusses bamboo production and management, including manipulation of growth and development and environmental aspects of bamboo production. Chapter 5 addresses a significant worldwide issue - management of soils for food security and environmental quality. Chapter 6 is a comprehensive review on the management of wheat, barley, and oat root systems.
