Book Effects of DDT Spray on Fish and Aquatic Insects in Gallatin River Drainage in Montana

Download or read book Effects of DDT Spray on Fish and Aquatic Insects in Gallatin River Drainage in Montana written by W. R. Bridges and published by . This book was released on 1961 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: DDT was sprayed at 0.5 pound per acre for elm spanworm control in two drainages in north Georgia in both 1959 and 1960. In one drainage, precautions were taken to avoid the stream, and no significant mortality to aquatic organisms resulted. In the other drainage, DDT reached the stream in a normal spray operation, and serious depletion of aquatic invertebrates resulted. Recovery of bottom organisms was rapid, and total numbers of invertebrates were up to pre-treatment levels after four months.

Book The Ecology of Regulated Streams

Download or read book The Ecology of Regulated Streams written by James Ward and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for an international symposium on regulated streams was conceived over an open-faced sandwich at the R&dhus in Copenhagen when we attended the Congress of the Societas Internationalis Lim nologiae in summer 1977. Although· we were aware that various col leagues were working on ecological problems in reservoir tailwaters, we did not fully comprehend the magnitude of worldwide stream regu lation nor the extent of interest in the subject. Such revelations are reflected in the 21 papers included in this book. The authors have summarized current understanding of the ecology of regulated streams and attempted to convey the importance and direction of future scientific investigations in stream ecosystems altered by upstream impoundments. The First International Symposium on Regulated Streams was the plenary event at the 27th annual meeting of the North American Benthological Society, April 18-20, 1979, in Erie, Pennsylvania. More than 500 colleagues attended. We gratefully acknowledge the support granted by the National Science Foundation; these funds permitted intellectual exchange between scientists from eight coun tries on four continents. We extend personal thanks to Dr. K. W. Stewart, President of NABS, and the NABS Program Committee, including Drs. E. C. Masteller, E. R. Brezina, and W. P. Kovalak. These individuals and other officers and members of the Executive Committee assisted us with the many details leading to organization and staging of a scientific forum. Discussions with Dr. John Cairns, Jr. and Dr. G. Richard Marzolf during the early planning stage were most helpful.
