Mercury in bats from the northeastern United States

摘要: This study examines mercury exposure in bats across the northeast U.S. from 2005 to 2009. We collected 1,481 fur and 681 blood samples 8 states analyzed them for total Hg. A subset (n = 20) are also methylmercury (MeHg). Ten species of represented this which two protected by Endangered Species Act (ESA 1973) other pending review. There four objectives paper: (1) examine correlates differences fur–Hg levels among all sampling sites, including age, sex, species, presence a Hg point source; (2) define relationship between factors that influence reproductive status, energetic condition; (3) determine relationships MeHg five common eastern bat species; (4) assess distribution populations northeast. found was eight times higher captured near sources compared nonpoint sources. Blood–Hg were well correlated with females on average accumulating more than males. On accounted 86 % (range 71–95 %) fur. Considering had high concentrations, beyond established concern, suggests there could be negative implications since is readily transferred pups via breast milk. Bats provide an integral part ecosystem their protection considered priority. More research needed if stressor negatively impacting populations.
