Download or read book Monitoring Ecological Condition at Regional Scales written by Shabeg S. Sandhu and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Environmental Monitoring and Assessment Program was created by EPA to develop the capability for tracking the changing conditions of our natural resources and to give environmental policy the advantages ofa sound scientific understanding of trends. Former EPA Administrators recognized early that contemporary monitoring programs could not even quantify simple unknowns like the number of lakes suffering from acid rain, let along determine if national control policies were benefiting these lakes. Today, adding to acidification impacts are truly complex problems such as determining the effects of climate change, of increases in ultraviolet light, toxic chemicals, eutrophication and critical habitat loss. Also today, the Government Performance and Results Act seeks to have agencies develop performance standards based on results rather than simply on levels of programmatic activities. The charge to EMAP of ecosystems is, therefore, the same today as it was a with respect to measuring the condition decade ago. We welcome the increasing urgency for sound scientific monitoring methods and data by efforts to protect and improve the environment. Systematic nationwide monitoring of natural resources is more than anyone program can accomplish, however. In an era of declining budgets, it is crucial that monitoring programs at all levels of government coordinate and share environmental data. EMAP resources are dwarfed by the more than $500 million spent on federal monitoring activities each year.

Download or read book Marine Biodiversity written by H. Queiroga and published by Springer Science & Business Media. This book was released on 2007-02-03 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the four sub-themes of the 38th European Marine Biology Symposium. These are patterns and processes, assessment, threats and management and conservation. Understanding the functioning of marine ecosystems is the first step towards measuring and predicting the influence of Man, and to finding solutions for the enormous array of problems we face today. The papers in this book represent current research and concerns about Marine Biodiversity in Europe.

Download or read book Metal Ecotoxicology Concepts and Applications written by Michael C. Newman and published by CRC Press. This book was released on 2020-11-25 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth discussion of various aspects of metal ecotoxicology. State-of-the-art information and techniques in areas ranging from metal behavior in surface waters to bioaccumulation kinetics and toxicokinetics to community effects are presented in a hierarchical arrangement. Specific topics discussed include metals in abiotic components of ecosystems, autecology (effects of metals relative to the individual or a single species), and metals in marine and freshwater systems in the context of synecology (species associated and interacting as a unit). This is an important book that will be useful to researchers, risk assessment consultants, regulatory personnel, and teachers and students.

This book was released on 1987 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report develops the theoretical foundation for analytical description and quantification of habitat structure. The analytical description of environmental gradients is shown to be an eigenanalysis problem, mathematically equivalent to the largest eigenvector (or first principal component) of a principal components analysis. The analytical representation of an environmental gradient, itself a single variable, is empirically demonstrated to have similar ecological information as the combination of all the original 58 habitat variables describing five Mojave Desert study sites. Two vastly different data bases were analyzed to explore the effects of sample sizes and variable selection on the ordination of study sites in both principal components and canonical variate space. Merits and shortcomings of principal components analysis, canonical analysis of discriminance, and cluster analysis for the ordination and classification of samples are reviewed in detail. Canonical analysis of discriminance is a very effective mechanism for classifying samples into a priori established groups, or for identifying variables that contribute significantly to group discrimination.
