This dataset includes timber harvest treatments; mercury concentrations in aquatic macroinvertebrates, salamanders, and riparian songbirds; carbon and nitrogen stable isotopes in aquatic macroinvertebrates and salamanders; and Bayesian estimates of food web length, basal resource diversity, and isotopic niche size for individual feeding guilds.

This data release includes sampling location data; field-collected stream attribute data; laboratory-analyzed chemistry concentrations (total mercury, methyl mercury) and isotopic composition (total mercury, carbon, and nitrogen) for stream biota (seston, periphyton, benthic insects, emerging adult insects, riparian spiders, and fish); density, body length, and taxonomic information for benthic insects; and density, biomass, and taxonomic information for emerging adult aquatic insects for biota sampled from stream reaches up and downstream of an historical mercury mine site. Sampling took place during summer low-flow conditions in 2015 and 2016. Stream reaches were located on U.S. Forest Service land near the Cinnabar Mine Site in the vicinity of Yellow Pine, ID, USA. Version 2.0 includes an additional table which describes subsampling of the Hess samples during processing. All data on benthic macroinvertebrates derived from Hess samples should be interpreted using this information about proportion of sample processed.

Comma-separated values (.csv) file containing data related to amphibian sampling across the United States between 2016 and 2021. Data files contain mercury concentrations in amphibian and dragonfly tissues, mercury concentrations in sediment, as well as amphibian morphometrics, and habitat and climate characteristics where the samples were collected.
