Book excerpt: "In this important new book on the declining health of one of America's leading environmental treasures, Howard Ernst reveals a Chesapeake bay that has become functionally dead. He argues that the Chesapeake Bay succumbed to a "light green" environmental movement that has too often adopted a philosophy of compromise over confrontation and that has fueling a "political dead zone" where political leaders posture but fail to make the hard decisions needed to achieve real improvement in the Bay's health. While blunt in his evaluation of past and present failures to restore the Bay, Ernst believes that there is still time to turn the restoration effort around and sets out new "dark green" strategies to do so. In the concluding chapter, five long-time bay activists provide first-person accounts of their battles and hopes for the future. Hailed by Robert F. Kennedy Jr. as "a must read for anyone concerned about environmental protection," this challenging book provides a wake-up call for everyone concerned about the future of the Chesapeake Bay and other ecological treasures through out America."--pub. desc.

This book was released on 1982 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual for the identification of larval fishes of the Great Lakes basin with emphasis on the Lake Michigan drainage treats 24 families and 148 species. In addition to a key to the families, keys were constructed for selected species within some families. Species accounts include descriptions of adult ecology, reproductive biology, diagnostic characters and meristics. A description of the egg is given, as are morphometric, morphological and pigmentation characteristics of yolk-sac larvae, larvae and juveniles. Illustrations of yolk-sac larvae, larvae and juveniles have been included wherever possible and informative.

Download or read book The Development of Fishery Compartments and Population Rate Coefficients for Use in Reservoir Ecosystem Modeling written by George R. Leidy and published by . This book was released on 1977 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of analyses designed to develop model fishery compartments and associated fish population rate coefficients on a regional basis for use in reservoir ecosystem modeling are presented. Emphasis is directed toward development of regional rate coefficients for the United States corresponding to major geographical drainage areas. Fishery data will be incorporated in the reservoir ecosystem model currently being developed by personnel of the Environmental Effects Laboratory, U.S. Army Engineer Waterways Experiment Station. Known physical, chemical, and fishery conditions in 187 Corps of Engineers (CE) impoundments larger than 500 acres are described. Multivariable equations are presented that allow estimation of standing crop and sport fish harvest in CE reservoirs. Data were also reviewed and summarized on the ecological growth and assimilation efficiencies of fish, food consumption rates, respiration rates, temperature tolerances, half-saturation constants for growth, and chemical composition.

Download or read book Modeling Coastal Hypoxia written by Dubravko Justic and published by Springer. This book was released on 2017-05-03 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a snapshot of representative modeling analyses of coastal hypoxia and its effects. Hypoxia refers to conditions in the water column where dissolved oxygen falls below levels that can support most metazoan marine life (i.e., 2 mg O2 l-1). The number of hypoxic zones has been increasing at an exponential rate since the 1960s; there are currently more than 600 documented hypoxic zones in the estuarine and coastal waters worldwide. Hypoxia develops as a synergistic product of many physical and biological factors that affect the balance of dissolved oxygen in seawater, including temperature, solar radiation, wind, freshwater discharge, nutrient supply, and the production and decay of organic matter. A number of modeling approaches have been increasingly used in hypoxia research, along with the more traditional observational and experimental studies. Modeling is necessary because of rapidly changing coastal circulation and stratification patterns that affect hypoxia, the large spatial extent over which hypoxia develops, and limitations on our capabilities to directly measure hypoxia over large spatial and temporal scales. This book consists of 15 chapters that are broadly organized around three main topics: (1) Modeling of the physical controls on hypoxia, (2) Modeling of biogeochemical controls and feedbacks, and, (3) Modeling of the ecological effects of hypoxia. The final chapter is a synthesis chapter that draws generalities from the earlier chapters, highlights strengths and weaknesses of the current state-of-the-art modeling, and offers recommendations on future directions.
