Book Description
This report characterises the variation in life history traits important to biological productivity in two of the key fish species in the Lower Slave River: inconnu and burbot, both piscivorous throughout most of their lives, abundant in the river, and important for both commercial and Aboriginal subsistence harvest. Specifically, the report describes size at age, the seasonal pattern of sexual maturity development with time, age at maturity, size and age-specific fecundity, and the population age structure of those two species.

Book Description
This book provides a comprehensive review of the relevant literature on managing conflicts stemming from the quantity and quality problems of water around the world. So far, few comprehensive and interdisciplinary analyses of such international surface water conflicts have been produced. The literature surveyed indicates that while in many areas there has been extensive research and analysis, there continues to be a need for more studies on the specific situations that lead to conflicts over water and other environment resources. Lateral learning, an attempt to understand the similarities between all conflicts over natural resources, will lend itself to future applications in predicting and preventing these conflicts. A survey of internati9nal watersheds provides some bibliographical and general data collected from over 200 transboundary watersheds. A subset of case studies of the exhaustive list of international watersheds is examined in greater detain. A related effort is a compilation and analysis of relevant water treaties, and the rationale for their implementations.

Book Description
Recent studies of past climate and streamflow conditions have broadened understanding of long-term water availability in the Colorado River, revealing many periods when streamflow was lower than at any time in the past 100 years of recorded flows. That information, along with two important trends-a rapid increase in urban populations in the West and significant climate warming in the region-will require that water managers prepare for possible reductions in water supplies that cannot be fully averted through traditional means. Colorado River Basin Water Management assesses existing scientific information, including temperature and streamflow records, tree-ring based reconstructions, and climate model projections, and how it relates to Colorado River water supplies and demands, water management, and drought preparedness. The book concludes that successful adjustments to new conditions will entail strong and sustained cooperation among the seven Colorado River basin states and recommends conducting a comprehensive basinwide study of urban water practices that can be used to help improve planning for future droughts and water shortages.

Book Description
The Niger River Basin, home to 100 million people, is a vital yet complex asset for West and Central Africa. It is the continent's third largest river basin, traversing nine countries -Benin, Burkina Faso, Cameroon, Chad, C©þte d'Ivoire, Guinea, Mali, Niger, and Nigeria. The River embodies both these nations' livelihoods and their geopolitics. It is not simply water but rather an origin of identity, a route for migration and commerce, a source of conflict, and a catalyst for cooperation. Cooperation among decision-makers and users is crucial to address the threats to water resources. The Niger.

Book Description
Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
