Book Description
The International Society of Root Research sponsored the Symposium "Root Demographics and Their Efficiencies in Sustainable Agriculture, GrassLands and Forest Ecosystems," July 14-18, 1996, at the Madren Conference Center, Clemson University, Clemson, South Carolina, USA. The conference was a continuation of a series of international symposiums on root research held every three to four years. Symposiums have also been held twice in Vienna, Austria, and once in Uppsala, Sweden, and Almaty, Kazahkstan prior to the meeting at Clemson University. The sponsoring society has made a particular effort in these symposia to include root scientists from the former Soviet Union because of the importance of exchanging information on a worldwide basis. This symposium continued and promoted that effort by providing travel grants to several scientists from that region; however, funds for that purpose were limited. Therefore, in compiling these proceedings, a number of papers from scientists from the former Soviet Union and former Warsaw Pack countries have been included even though the scientists were not actually present for the SymPOSIum.

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 decade since the publication of the third edition of this volume has been an era of great progress in biology in general and the plant sciences in particular. This is especially true with the advancements brought on by the sequencing of whole genomes of model organisms and the development of "omics" techniques. This fourth edition of Plant Root

Book Description
Ecology at the ecosystem level has both necessitated and benefited from new methods and technologies as well as those adapted from other disciplines. With the ascendancy of ecosystem science and management, the need has arisen for a comprehensive treatment of techniques used in this rapidly-growing field. Methods in Ecosystem Science answers that need by synthesizing the advantages, disadvantages and tradeoffs associated with the most commonly used techniques in both aquatic and terrestrial research. The book is divided into sections addressing carbon and energy dynamics, nutrient and water dynamics, manipulative ecosystem experiements and tools to synthesize our understanding of ecosystems. Detailed information about various methods will help researchers choose the most appropriate methods for their particular studies. Prominent scientists discuss how tools from a variety of disciplines can be used in ecosystem science at different scales.
