olorados Front Range represents a region of the Southern Rockies LCC that is both ecologically and economically significant. It is home to the majority of Colorados residents, including the major population centers of Denver, Fort Collins, Boulder, and Colorado Springs, and provides critical ecosystem services such as clean and abundant water, wildlife habitat, recreation opportunities, and aesthetic values to the rest of the state. Ponderosa pine (Pinus ponderosa) dominated forests span the majority of the Front Range mountains and foothills, covering approximately 700,000 acres of the Front Range landscape between 5000 and 8500 ft elevation. The lower-montane zone ponderosa pine forests (~5500-7000 ft) form the...

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...

Climate change has become a serious threat across the U.S. and nowhere in the U.S. is this more evident than in the potential impacts to the species inhabiting the low-lying Florida Keys. Over 30 threatened, endangered, candidate and at-risk species occur in the Florida Keys. Developing and implementing adaptation strategies is a critical part of planning for the survival of these unique species. A systematic and programmatic look at the threats, species and their habitats in the Florida Keys will leverage existing resources. This project will use a stakeholder-based process to identify and target alternative actions where changes to, or additional guidance may improve our ability to address climate change in our...
The article discusses a report published by the U.S. Dept. of Energy (DOE) that examined the technical feasibility of using wind energy for electricity generation. The report assessed the costs, impacts and challenges associated with the production of 20% wind energy by 2030. Results have shown that there is a need for an enhanced transmission infrastructure and an increase in turbine installations to achieve 20% wind energy.
By replacing fossil fuels bioenergy has the potential to reduce greenhouse gas (GHG) emissions, but indirect effects might partly or even completely eliminate this benefit. Production of bio-energy products, such as biofuels for transport, causes several indirect effects through their interactions with the global economic and physical systems. Indirect land-use change leads to GHG emissions – in some cases in the same order of magnitude as the fossil emissions – and loss of nature, but there are other relevant indirect effects as well. Intensification of agricultural production is another indirect effect and could be stimulated more to minimise the undesirable land conversion. However, intensification through increased...
One of the highest priorities in carbon sequestration science is the development of techniques for CO2 separation and capture, because it is expected to account for the majority of the total cost ( 75%). The most common currently used method of CO2 separation is reversible chemical absorption using monoethanolamine (MEA) solvent. In the current study, solvent degradation from this technique was studied using degraded MEA samples from the IMC Chemicals Facility in Trona, California. A major pathway to solvent degradation that had not been previously observed in laboratory experiments has been identified. This pathway, which is initiated by oxidation of the solvent, is a much more significant source of solvent degradation...
The Arctic National wildlife Refuge (ANWR) , located on the Alaska North Slope, is believed to contain high petroleum production potential. This region also has outstanding wildlife and wilderness values. Currently ANWR is closed to oil and gas leasing. However, Congress is considering an Interior Department recommendation to open a portion of ANWR to oil and gas production. Environmentalists maintain that petroleum exploration and development will have severe environmental effects on the calving activities of one of the largest caribou herds in the Arctic, negative impacts on the peregrine falcon, lesser snow goose, and muskox populations, as well as other detrimental environmental consequences. A draft study by...
The increased urgency of dealing with mitigation of the looming climate change has sparked renewed interest in the nuclear energy option. There exists a substantial stream of research on the amount of embodied energy and greenhouse gas emissions associated with nuclear generated electricity. While conventional fossil fuelled power plants cause emissions almost exclusively from the plant site, the majority of greenhouse gas emissions in the nuclear fuel cycle are caused in processing stages upstream and downstream from the plant. This paper distils the findings from a comprehensive literature review of energy and greenhouse gas emissions in the nuclear fuel cycle and determines some of the causes for the widely varying...
As policy makers consider strategies to reduce greenhouse gas emissions, they need to understand the available options and the conditions under which these options become economically attractive. This paper explores the economics of carbon capture and sequestration technologies as applied to electric generating plants. The MIT Emissions Prediction and Policy Analysis (EPPA) model, a general equilibrium model of the world economy, is used to model two of the most promising carbon capture and sequestration (CCS) technologies. The CCS technologies are based on a natural gas combined cycle plant and an integrated coal gasification combined cycle plant. Additionally, the role of natural gas combined cycle plants without...

Tidal energy has the technical potential to form part of a low carbon electricity sector, however, its ‘social potential’ is less clear, as few empirical studies of public beliefs and responses have been conducted to date. This research addressed this gap by investigating a tidal energy convertor in Northern Ireland, said to be the first grid-connected device of its kind in the world. Data was collected from 313 residents of two nearby villages using mixed methods, guided by a conceptual framework that avoided ‘NIMBY’ assumptions and instead drew on place theory. Findings indicated strong support for the project, arising from beliefs that the project enhanced local distinctiveness by ‘putting the area on the map...
