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.

The northern leopard frog (Rana pipiens) is a formerly abundant frog that has experienced significant declines across its range and is considered endangered in some parts of the range but still abundant in other parts of the range. Various factors have been invoked to explain population declines in the northern leopard frog, including habitat destruction, diseases, chemical contamination, acidification, increased ultraviolet light due to loss of the ozone layer, introduced predators, overcollecting, climatic changes, and general environmental degradation. However, no one cause has emerged as the primary factor behind population declines in any area. Probably, multiple causes contribute to population...

The midget faded rattlesnake (Crotalus viridis concolor) has long been considered a subspecies of the western rattlesnake (C. viridis). This document will follow this convention, although there is some discussion of taxonomic revision at the species level that would categorize the midget faded rattlesnake as C. oreganos concolor (Crother et al. 2003). Midget faded rattlesnakes are a pale brownish gray, cream, or straw color. Blotches on the body are faded, subrectangular or sub-elliptical. As with most rattlesnakes, the most distinguishing feature is the rattle. Midget faded rattlesnakes are pit vipers, with the typical heat-sensing pits on each side of the head, between the eyes and mouth, used for detecting prey....

This dataset depicts the cooperative interagency 1:24,000 scale land ownership status for the State of Utah. Administrative ownership polygons are updated by The State of Utah School and Institutional Trust Lands Administration (SITLA) and the United States Bureau of Land Management (BLM) Salt Lake City office on a regular basis. Revisions are posted monthly. This data was originally digitized for the 1993 U. S. Fish and Wildlife Utah GAP Analysis project by the Remote Sensing and GIS Laboratories, Department of Geography and Earth Resources, Utah State University (RSGIS/USU). Maintenance of this data layer is performed by a cooperative federal and state effort. The Utah School and Institutional Trust Lands Administration...
