Market forces and technological substitutes cause fluctuations in the value of bat pest-control services for cotton

This study explores the effects of market forces and substitutes on ecosystem service values by assessing how the value of the pest-control services provided by Mexican free-tailed bats to cotton producers in the United States has changed over time. The data from 1990 through 2008 shows that the ecosystem service value of the bats provided to cotton producers declined by 79% due to the widespread adoption of Bt cotton, which is transgenically modified to express its own pesticide, plus declines in the market price of cotton. However, with the possible evolution of pest resistance to Bt cotton, the value of bat pest-control services may increase again, giving rise to an economic option value argument for conserving Mexican free-tailed bat populations.

Unmanned Aircraft Systems (UAS) Project Manager Mike Hutt and Cartographer Jeff Sloan are quoted in the O'Reilly Radar article "Drone on: UAVs will rule the skies (unless the FAA says otherwise)". In the story Mike presents the example of a mapping project in White Sands National Monument that benefitted from the use of UAS, specifically the high resolution imagery they were able to obtain over the project area. The cost benefits to using this technology, project challenges, as well as increased use of UAS by research organizations are also discussed.

Created and hosted at the GECSC, the new Interior Geospatial Emergency Management System (IGEMS) website offers the public and emergency management communities online maps containing the latest available information on earthquakes, earthquake shakemaps, streamflow data, floods, volcanoes, wildfires, as well as information on severe weather hazards. This site replaces the Natural Hazards Support System (NHSS), which was one of the first public applications to provide an integrated approach in incorporating a wide range of hazards into a dynamic mapping environment. Since IGEMS uses the latest software and technology, it provides functionality beyond that of the NHSS system, including support for mobile devices such as tablets and smartphones.
