Can wetland water-management influence mercury bioaccumulation in songbirds and ducks at National Wildlife Refuges with mercury problems?

During summer 2017, Northern Prairie Wildlife Research Center (NPWRC) initiated a collaborative research study focused on understanding if water-level management of wetlands at refuges can influence mercury bioaccumulation in wetland-dependent migratory birds.  Birds are susceptible to the effects of mercury and can serve as indicators of contamination in ecosystems. We examined mercury...

Contaminants in Waterbirds and Effects on Avian Reproduction

California’s Central Valley and San Francisco Bay Estuary have a long history of mercury contamination from past mercury mining and gold extraction. Waterbirds are particularly susceptible to mercury because of their use of wetland habitats where methylmercury (the most toxic and biologically available form) is produced and relatively low methylmercury exposure can reduce reproductive success...
