We examined bird and bat mortality at a new 89-turbine windfarm constructed in an environmentally sensitive area in north-central Iowa. The windfarm became operational in November 2001. It is located in cropland between three Wildlife Management Areas (WMA's) with historically high bird use. In the past, migrant and resident waterfowl, shorebirds, raptors, and songbirds moved between the WMA's through the area now occupied by the windfarm. Studies of bird collision mortality in California and elsewhere raised concerns about the possibility of mortalities in this area. From April 15, 2003 and December 15, 2003 we searched for dead animals under 26 randomly selected turbines. Six 76.2 m by 3.0 m transects were maintained...
A method is investigated for increasing the utilization efficiency of energy resources and reducing environmental emissions, focusing on utility-scale cogeneration and the contributions of nuclear energy. A case study is presented for Ontario using the nuclear and fossil facilities of the main provincial electrical utility. Implementation of utility-based cogeneration in Ontario or a region with a similar energy system and attributes is seen to be able to reduce significantly annual and cumulative uranium and fossil fuel use and related emissions, provide economic benefits for the province and its electrical utility, and substitute nuclear energy for fossil fuels. The reduced emissions of greenhouse gases are significant,...
In the last decade, climate change has been one of the major concerns with regard to the health of the earth's ecosystem. The problem of a changing climate is related to not only climate, energy consumption and emissions of greenhouse gases, but also effects of such a change on the earth's ecosystems, resources and human settlements, as well as the need to reduce or avoid these effects. In this study, an inexact-fuzzy multiobjective programming model was proposed for adaptation planning of land resources management in the Mackenzie Basin under changing climate. This integrated adaptation planning enables the inclusion of systems interaction and feedback mechanisms and can therefore yield insights that scattered...
We discuss that whilst energy conservation and energy efficiency both ultimately have the same goal they attempt to achieve this via very different approaches. We then discuss how both options face significant barriers to ultimately successfully reduce electricity consumption.

For each damage agent, a composite index was created by analyzing the ADS data for the past 5 years (2005 - 2010) collectively to identify those epicenters of high mortality and adjacent areas to determine the potential for future mortality. The areas adjacent to existing mortality where futuremortality has a greater chance of occurring.To achieve this, a simple crosswalk was completed.Number of Years of Mortality Current Forest Mortality IndexFuture Risk of Mortality (Next 5 Years)0Non-Infested Low1-2Low to Low-Moderate Moderate3-4`Moderate to Moderate-High High>5HighVery High These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions.

Species distribution models often use climate data to assess contemporary and/or future ranges for animal or plant species. Land use and land cover (LULC) data are important predictor variables for determining species range, yet are rarely used when modeling future distributions. In this study, maximum entropy modeling was used to construct species distribution maps for 50 North American bird species to determine relative contributions of climate and LULC for contemporary (2001) and future (2075) time periods. Results indicate species-specific response to climate and LULC variables; however, both climate and LULC variables clearly are important for modeling both contemporary and potential future species ranges....

Efforts to model and predict long-term variations in climate-based on scientific understanding of climatological processes have grown rapidly in their sophistication to the point that models can be used to develop reasonable expectations of regional climate change. This is important because our ability to assess the potential consequences of a changing climate for particular ecosystems or regions depends on having realistic expectations about the kinds and severity of change to which a region may be exposed.The fifth phase of the Coupled Model Intercomparison Project (CMIP5) is a collaborative climate modeling research effort coordinated by the World Climate Research Programme (WCRP). This is the most recent phase...

Federally owned and managed public lands occupy approximately 30 percent of the land area of the United States, and anywhere from 50 percent to more than 80 percent of the land area of many of the western states. Determining the appropriate use of these lands involves balancing objectives related to economic, recreational, and conservation interests. This paper examines established and emerging conflicts within and across these objectives through both a narrative discussion of specific topics and a series of case studies. The authors find that new challenges, including pressures to devote portions of public lands to renewable energy project development and the multifaceted threats presented by climate change, will...

Large deposits of recoverable lignite (> 16 billion tons) occur in parts of Alabama, Arkansas, Louisiana, Mississippi, and Texas. Commercial surface mining of these reserves has occurred only in eastern Texas, but additional mining has been proposed for Texas and the other states during the 1980's. Almost all of the new mining would occur in the Southeastern Mixed Forest· (Pineywoods) ecoregion, and the Prairie Parkland ecoregion of eastern Texas. Potential impacts on fish and wildlife will be lessened because of the enactment of the Surface Mining Control and Reclamation Act of 1977 (P.L. 95·87) and the permanent program regulations. However, major impacts on fish. and wildlife may still occur as a result of habitat...

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...

A review of the four main wood energy sectors in the U.S. was conducted to explore historic trends and the impact of alternative energy prices and public policies on wood energy consumption. High oil prices have triggered the adoption of government regulation and financial incentives to promote greater use of wood energy over the last four decades. However, the amount of wood energy consumed in the U.S. industrial sector was driven mainly by the output of the pulp and paper products industry and not by energy prices or any particular public policy incentive. Residential consumption of wood energy was positively correlated with competing energy prices. Public policies seem to have had a greater impact on wood energy...
