OverviewBRI Monitoring Program for Mercury in Mammals. Samples are from a variety of projects, primarily in the eastern U.S. and Canada. Data mostly date from 2000 onwards; older data are mostly from trappers and do not have georeferences. Dataset includes multiple tissues from bats, rodents, and furbearers. THg, MeHg, and a variety of ancillary data. Source Agency: BioDiversity Research Institute ContactDave Yates, Mammal Program Director Address Phone: 207-839-7600 x114 Fax: 207-839-7655 |
