Mercury Exposure in Piscivorous Birds at the Carson River (NV) Superfund Site, 1997-2006

The persistence and degree of mercury contamination of the lower Carson River system (LCRS) have led to placement of a portion of the Carson River Basin (including Lahontan Reservoir) on the US. Environmental Protection Agency (EPA) National Priorities List ("Superfund") for research and cleanup. The potential toxicity of mercury concentrations within the LCRS to piscivorous b

Total Mercury Concentrations in Fish Muscle from the Colorado River and Bright Angel Creek, AZ, USA (2015)

Mercury is a globally distributed pollutant that threatens human and ecosystem health. Even protected areas, such as national parks, are subjected to mercury contamination because it is delivered via atmospheric deposition, often after long-range transport. In aquatic ecosystems, certain environmental conditions can promote microbial processes that convert inorganic mercury to an organic

Simulated data supporting inbreeding rate estimates from incomplete pedigrees

This data release includes: (1) The data from simulations used to illustrate the behavior of inbreeding rate estimators. Estimating inbreeding rates is particularly difficult for natural populations because parentage information for many individuals may be incomplete. Our analyses illustrate the behavior of a newly-described inbreeding rate estimator that outperforms previously described ap...
