Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Download or read book Air Pollution and Its Impacts on U S National Parks written by Timothy J. Sullivan and published by CRC Press. This book was released on 2017-02-03 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variety of air pollutants are emitted into the atmosphere from human-caused and natural emissions sources throughout the United States and elsewhere. These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.

Download or read book Biogeochemical Monitoring in Small Catchments written by Jiří V. Černý and published by Springer Science & Business Media. This book was released on 1995 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The BIOGEOMON conference, held in Prague, September 1993, was dedicated to the use of geochemistry and biology in the elucidation of biogeochemical processes in the context of research on small catchments, which are natural systems that lend themselves to the study of environmental problems at the ecosystem level. Biogeochemical Monitoring in Small Catchments, which contains reviewed papers from the conference, includes long-term studies of nutrient cycling in forested catchments, effects of anthropogenic action on streamwater chemistry, stable isotope studies for tracing biogeochemical processes, determination of the process rates, and mathematical modelling of ecosystem behaviour and mass fluxes. For research scientists and students of ecology, biology, hydrology and geochemistry as well as professionals in natural resources management.

Download or read book Limnology of Mountain Lakes written by J. Fott and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented either in oral or poster form at the international symposium `Limnology of Mountain Lakes', held at Stará Lesná (Slovakia) between 1 and 7 July 1991. Several papers covered contributions from the fields of physical and chemical limnology, palaeolimnology, zooplankton, phytoplankton and phytobenthos, and bacteria. Acidification, a process affecting water chemistry and biota of many mountain lakes in Europe was dealt with also. A series of papers on the lakes in Sumava has highlighted different aspects of these lakes, which are in the last stage of acidification. Other geographical areas covered extensively were the Tatras and the Alps.

Download or read book The Lakes of the Basin of Mexico written by Carlos E. Cordova and published by Springer Nature. This book was released on 2022-11-01 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a review of research on the prehistoric and historic evolution of the Basin of Mexico’s lacustrine systems. Based on this review, the book presents a model of long and short-term natural lacustrine dynamics as the basis for understanding the processes of human adaptation and transformation of the aquatic ecosystems of the Basin of Mexico. Although only remains of the former lakes exist, the book stresses the importance of the knowledge of the former natural and cultural history of the lakes. In this sense, the book addresses the misconceptions and misinterpretations of the lakes that still exist in the literature and the media and that do not reflect the real nature of the lakes in the past. Therefore, the book attempts to not only feed into the local knowledge of the lakes, but also contribute to the worldwide knowledge of lacustrine dynamics and human populations that lived in and around them. The book should be of interest to geographers, geologists, archaeologists, natural historians and environmental scientists, civil engineers, city planners and those involved in the management of natural resources.
