The Manual on Uniform Traffic Control Devices (MUTCD) specifies minimum retroreflectivity
requirements that include an obligation for agencies to develop a strategy for maintaining
compliance. States were given a deadline of January 1, 2012 for the implementation of an
assessment or management plan, which led to an increased emphasis on...
Background: Academic medical centers are examining relationships with the pharmaceutical industry
and making changes to limit interactions. Most doctors, however, practice outside of academic institutions
and see pharmaceutical detailers and accept drug samples and gifts. Little guidance for practicing
physicians exists about transforming practices to become pharma-free. Consideration must be...
A major goal in greater sage-grouse (Centrocercus urophasianus, hereafter ‘sage-grouse’) conservation is to spend limited resources efficiently by conserving large and functioning populations. We used maximum count data from leks (n = 4,885) to delineate high abundance population centers that contain 25, 50, 75, and 100% of the known breeding...
Mercury (Hg) is a globally distributed environmental
contaminant with a variety of deleterious effects
in fish, wildlife, and humans. Breeding songbirds may be
useful sentinels for Hg across diverse habitats because they
can be effectively sampled, have well-defined and small
territories, and can integrate pollutant exposure over time
and space....

The compositions and loadings of organic matter in soils and sediments from a diverse range of environments along the Fly River system were determined to investigate carbon transport and sequestration in this region. Soil horizons from highland sites representative of upland sources have organic carbon contents (%OC) that range from...
