Methylmercury and associated data in macroinvertebrates from tributaries of Honnedaga Lake and from the Middle Branch Black River in New York. Macroinvertebrate samples were collected from streams tributary to Honnedaga Lake and from the Middle Branch of the Black River during 2012-2016 and analyzed for methylmercury concentrations and for stable isotope ratios of nitrogen and carbon. Macroinvertebrates were identified in the field, and the level of taxonomic resolution varied from order to species; most taxa were identified to the family level. Specimens were field-processed into composite samples, field-frozen, and submitted to the mercury laboratory for freeze-drying and analysis. Subsamples were then submitted to the stable isotope laboratory for analysis of nitrogen and carbon isotope ratios. This database contains the resulting data and associated...

Concurrently, macroinvertebrates were sampled annually between 2013 and 2016 at 3 treated and 3 untreated reference sites to assess the effects of each liming technique on this community. Macroinvertebrate communities were monitored at 6 study sites: T16, T8A (50 m upstream of lime application point), T8 (50 m downstream of lime application point), T6 (1230 m downstream of the lime application point), and at two unlimed reference streams, T24 and T20. T24 is of similar... Categories: Data; Tags: Adirondack Mountains, Aquatic Biology, Ecology, Herkimer County, Honnedaga Lake, All tags...
