Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Color images throughout illustrate wetland indicators. Incorporates analysis and coverage of the latest Army Corps of Engineers delineation manual. Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation.

Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.

The Red Lake is a natural barrier lake at the foot of the Hasmasu Mare Mountains in the Eastern Carpathian Range in Romania. It was formed when the Bicaz River was blocked by a natural dam resulting from two landslides during an extreme heavy storm in 1837. This book presents an interdisciplinary and comprehensive study on the physical, chemical, geographical and ecological aspects of Red Lake (Lacu Rosu). The first three chapters cover the formation and geological setting and its relationship with the Bicaz Gorges-Haghimas national park. Subsequent chapters present the sedimentological, morphological and hydrological evolution of this unique natural laboratory and climatological setting. The final chapters deal with ecological aspects of Red Lake waters and adjacent ecosystems such as wetlands and water resource management issues.

Treatment Marshes for Runoff and Polishing represents the most comprehensive and up-date-date resource for the design, construction, and operation of marsh treatment systems. This new edition represents a complete rewrite of the surface flow sections of previous editions of Treatment Wetlands. It is based on the performance hundreds of treatment marshes over the past 40 years. Treatment Marshes focuses on urban and agricultural runoff, river and lake water improvement, and highly treated municipal effluents. New information from the past dozen years is used to improve data interpretation and design concepts. Topics included in this book are Diversity of marsh vegetation Analyses of the human use of treatment marshes New concepts of underground processes and functions Spectrum of marsh values spanning mitigation, restoration, enhancement, and water quality improvement Improved methods for calculation of evapotranspiration and wetland water temperatures Hydraulics of surface and subsurface flows in marshes Analysis of long track records for deterministic and probabilistic behavior Consideration of integrated microbial and vegetative contaminant removals via mass balances Uptake and emission of gases Performance of urban and agricultural wetlands Design procedures for urban and agricultural wetlands Reduction of trace metals, pesticides, pharmaceuticals, endocrine disruptors, and trace organics Updated capital and O&M economics, and valuation of ancillary benefits An updated list of over 1900 references
