Within the last 15 years, wastewater treatment plants have increasingly begun to find radioactive isotopes incorporated in biosolids. Regulations concerning the disposal of radioactive material via sanitary sewer systems were in place since the early 1960's and recently were further restricted. However, the updated regulations would not have prevented certain...
The Vermillion Basin, located in southwest Wyoming is an inhospitable, high altitude desert with unique biota and environmental conditions. The area has a long history of usages by humans including recreation, livestock grazing and mineral development. The natural gas industry has had a strong presence in the area since the...
This report documents and summarizes several decades of work on sage-grouse populations, sagebrush as habitat, and sagebrush community and ecosystem functions based on the recent assessment and findings of the USFWS under consideration of the Endangered Species Act. As reflected here, some of these topics receive a greater depth of...
The objective of the study is to generate accurate, current data on distribution (distance to shore, travel path) and behavior (travel speed, migration timing) of gray whales migrating along the central Oregon coast (Pacific Ocean). Migration paths of tracked whales seem to follow a constant depth rather than following the...
Unity Reservoir in Baker County, Oregon, was chemically treated with liquid rotenone on October 17, 1962. Approximately 136 miles of streams and diversion ditches and seven small ponds, tributary to the reservoir, were treated with liquid rotenone prior to work on the reservoir. The reservoir at time of treatment contained...
Vietnam’s marine fisheries are in need of knowledge-based management. This necessitates the establishment of
reliable indicators, which in turn entails a good data collecting and processing system. To bridge the gap between
specific requirements for fisheries policy development and the limited resources available, we have conducted a
study on costs...
