Habitat biogeochemistry was assessed by measuring 26 variables in sediments and porewater related to mercury content, organic matter, sediment characteristics, and microbial rates of sulfate reduction, iron reduction, and methanogenesis. Thirty-six composite surface (0-2 cm) sediment cores were collected in each of three wetlands in the spring and summer of 2005 and 2006.

Methylmercury (MeHg) is a globally pervasive contaminant that biomagnifies in food webs and can reach toxic concentrations in consumers at higher trophic levels, including wildlife and humans. The production of MeHg, and its subsequent entry and biomagnification in food webs, is governed by a complex suite of biogeochemical, physical, and ecological processes, resulting in variation in the distribution of MeHg among regions and individuals. To better understand spatial variation in MeHg bioaccumulation within a species, we evaluated the effects of habitat biogeochemistry, food web structure, and diet composition in the wetland-obligate California black rail (Laterallus jamaicensis coturniculus) at three wetlands...

NEAMAP stands for NorthEast Area Monitoring and Assessment Program. NEAMAP was developed to meet the needs of fisheries management and stock assessment activities in the northeastern United States. NEAMAP began in 2006 with a fall pilot survey and in 2008 began conducting both a spring and fall survey. NEAMAP samples from Cape Cod, MA south to Cape Hatteras, NC and targets both juvenile and adult fishes. NEAMAP is an integrated, cooperative state/federal data collection program. Its mission is to facilitate the collection and dissemination of fishery-independent information obtained in the Northeast for use by state and federal fisheries management agencies, the fishing industry (commercial and recreational),...

Methylmercury concentrations and stable isotope ratios were measured from back feathers of California black rails (Laterallus jamaicensis coturniculus) and six taxa of their invertebrate prey (Amphipoda, Arachnida, Coleoptera, Diptera, Gastropoda, and Hemiptera). Samples were collected from three wetlands in the spring and summer of 2005 and 2006.
