The distribution and abundance of the greater sage-grouse (Centrocercus urophasianus) have declined dramatically, and as a result the species has become the focus of conservation efforts. We conducted a range-wide genetic survey of the species which included 46 populations and over 1000 individuals using both mitochondrial sequence data and data from seven nuclear microsatellites. Nested clade and STRUCTURE analyses revealed that, in general, the greater sage-grouse populations follow an isolation-by-distance model of restricted gene flow. This suggests that movements of the greater sage-grouse are typically among neighbouring populations and not across the species, range. This may have important implications if...
In order to step up its efforts in reducing climate change, the European Commission (hereafter: the Commission) has launched in June 2000 its European climate change program (hereafter: ECCP). This wide-ranging stakeholder consultation aimed at identifying and developing all elements necessary for a European climate change strategy. The ECCP formally came to a close in April 2003. This paper analyses the inner workings of ECCP, and how ECCP has delivered with regard to its objectives. Special attention is paid to ECCP's Working Group 1, "Flexible Mechanisms", which developed the foundations for the European emission trading scheme (hereafter: EU ETS). The paper draws on documents published on the Commission's ECCP...
This paper formulates an input-output method for determining the distributional consequences of energy development projects. The method is oriented to the conditions appearing in many contemporary development settings where large resident populations and other factors are likely to inhibit boomtown scenarios. An analysis of geothermal energy development in Imperial County, California, is presented. The results indicate that personal income inequality is likely to increase by several percentage points as measured by the Gini coefficient. The sensitivity of the results is examined with respect to important factors such as labor supply elasticities, preferential employment of local residents, and the concentration...
