Crop Pollination Exposes Honey Bees to Pesticides Which Alters Their Susceptibility to the Gut Pathogen Nosema ceranae - While fungicides are typically seen as fairly safe for honey bees, we found an increased probability of Nosema infection in bees that consumed pollen with a higher fungicide load. Our results highlight a need for research on sub-lethal effects of fungicides and other chemicals that bees placed in an agricultural setting are exposed to. S. Pettis, Elinor M.

Impacts of Conservation Adoption on Cultivated Acres of Cropland in the Chesapeake Bay Region, 2003-06 to 2011 - On December 5, 2013, Secretary of Agriculture Tom Vilsack announced the release of the CEAP-Cropland report on the effects of recently installed conservation practices on cropland in the Chesapeake Bay region. This new report, using data collected in 2003-06 and 2011, demonstrates that during the time between the two surveys, agricultural producers have significantly increased their use of an array of conservation measures to improve and protect water and soil quality in the Chesapeake Bay region. These conservation practices are generating substantial natural resource benefits for producers and the communities of the Chesapeake Bay region.

Occurrence of Contaminants of Emerging Concern in Pennsylvania Waters, 2006-09 - Webinar held on 7/25/13 Ms. Rhonda Manning, Water Program Specialist PA Department of Environmental Protection, Mr. Andrew Reif, Water-Quality Biologist U.S. Geological Survey

Occurrence of Pharmaceuticals, Hormones, and Organic Wastewater Compounds in Pennsylvania Waters, 2006–09 - Far fewer numbers of contaminants of emerging concern were detected at the fish-health sites than at the wastewater-effluent-discharge sites. Most of the fish-health sites were not located directly downstream from a wastewater-effluent discharge, but there were multiple wastewater-effluent discharges in the drainage basins upstream from the sampling sites. No distinct pattern of contaminant occurrence could be discerned for the fish-health stream sites. Andrew G. Reif, J. Kent Crawford, Connie A. Loper, Arianne Proctor, Rhonda Manning, and Robert Titler
