Download or read book An Evaluation of the U S Navy s Extremely Low Frequency Submarine Communications Ecological Monitoring Program written by National Research Council and published by National Academies Press. This book was released on 1997-07-25 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Navy established an ecological monitoring program to determine whether electric and magnetic fields from extremely low frequency (ELF) communications systems influenced plant and animal populations near the transmitting facilities. Although some of the researchers believe that a few biological changes might have occurred, they concluded that the results do not indicate significant adverse ecological effects. This book evaluates the 11 ecological studies of the Navy's monitoring program and examines the adequacy of experimental design, the data collection and analysis, and the soundness of the conclusions. It also addresses whether the monitoring program was capable of detecting subtle effects due to ELF exposure and examines the biological changes observed by some program researchers, such as enhanced tree growth.

Download or read book Ecology and Conservation of Neotropical Migrant Landbirds written by Manomet Bird Observatory (Mass.) and published by Smithsonian Books (DC). This book was released on 1992 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than a decade ornithologists have suspected that migrant landbird populations in the United States and Canada are declining. Fragmented forests in the northern breeding grounds and the loss of habitats in tropical wintering zones have been suggested as two major factors in the population declines. This is the first technical volume to focus exclusively on the question of northern hemispheric migratory landbird declines and their conservation. More than one hundred leading scholars working in the Americas and the Caribbean report on the problems facing these birds and suggest strategies for research and conservation. The book details the basic ecology of many Neotropical migrant landbirds in both temperate and tropical regions. Individual reports--each with a Spanish abstract--probe the reasons for population changes, discuss species behavior during summer and winter months, and gauge the impact of environmental events on landbirds. This book arose out of a 1989 symposium at Woods Hole, Massachusetts, hosted by the Manomet Bird Observatory--a meeting widely credited for bringing Neotropical migrant landbird conservation to the forefront of attention.
