The Great Plains Landscape Conservation Cooperative (GPLCC, https://www.fws.gov/science/catalog) is a partnership that provides applied science and decision support tools to assist natural resource managers conserve plants, fish and wildlife in the mid- and short-grass prairie of the southern Great Plains. It is part of a national network of public-private partnerships — known as Landscape Conservation Cooperatives (LCCs, http://www.fws.gov/science/shc/lcc.html) — that work collaboratively across jurisdictions and political boundaries to leverage resources and share science capacity. The Great Plains LCC identifies science priorities for the region and helps foster science that addresses these priorities to support...
Because of the inevitable depletion of fossil fuels and the corresponding release of carbon to the environment, the global energy future is complex. Some of the consequences may be politically and economically disruptive, and expensive to remedy. For the next several centuries, fuel requirements will increase with population, land use, and ecosystem degradation. Current or projected levels of aggregated energy resource use will not sustain civilization as we know it beyond a few more generations. At the same time, issues of energy security, reliability, sustainability, recoverability, and safety need attention. We supply a top-down, qualitative model—the surety model—to balance expenditures of limited resources...
Human activity causes wintering waterfowl to expend energy to avoid humans at a time in their annual cycle when energy conservation is important to survival, migration, and breeding reserves. Understanding the effects of recreational activities on waterfowl is important to managing natural resource areas where migratory birds depend on wetland habitat for resting and feeding. We investigated responses of 7 species of dabbling ducks to 5 different experimental human activities, (a pedestrian, a bicyclist, a truck traveling at 2 different speeds, and an electric passenger tram). Responses of ducks depended on type of disturbance, species, and distance from disturbances. Most birds responded to the treatments. People...
This study shows that metal-contaminated sediments cause adverse biological effects at all levels of biological organization, from cellular to ecosystem-level responses, even where the corresponding surface water meets water-quality-based criteria. We studied the effects of contamination from the abandoned Alder Mine, Alder Mill, and Red Shirt Mill located near the town of Twisp on the eastern slopes of the north Cascade Mountains in Okanogan County, Washington (U.S.A.) on fish and wildlife habitat in the Methow River. Ore deposits in the area were mined for gold, silver, copper and zinc until the early 1950s. An up-gradient and down-gradient approach was used to compare impacted sites to control sites. Although...
In the spring of 2007 the Alberta Energy and Utilities Board (the 'Board') employed private investigators to covertly observe interveners in a hearing into the proposed construction of a transmission facility. This decision led to public outrage and, as well, to the Board's vacation of all its decisions related to the transmission facility on the basis that a reasonable apprehension of bias had arisen. This article places the Board's retention of the private investigators in the context of a number of other procedural decisions made by the Board in its consideration of the proposed transmission facility. It then reviews the totality of those decisions to suggest that, in designing an appropriate process, a regulatory...
