“…Though SIA signatures are known to exhibit extensive spatial variation (Guzzo et al 2011), a pattern we have observed for less-mobile organisms in the BDC system (Fletcher et al 2014b), the signatures of these highly mobile fishes did not differ between sites. Overall, stable isotope analyses identified a trophic hierarchy among species, with 2 specialized piscivores-Longnose Gar and Largemouth Bass-occupying the highest trophic position.…”

“…Although patterns and processes in the downstream site are not all independent from the upstream site, we sought to make comparisons based on unique hydrology and geomorphology found at each site. Previously reported differences between these sites include stable isotope signatures of invertebrates (Fletcher et al 2014b).…”

“…The ANOVA models were repeated including only the 4 fish species to confirm the reliance of the significant interaction term on spatial differences in the less-mobile invertebrates. Spatial variation of the invertebrates has been previously addressed (Fletcher et al 2014b).…”

“…Laboratory handling of M. modestum and Asiatic Clams are detailed in Fletcher et al (2014b). We analyzed a total of 13 M. modestum composite samples (site A: n = 5; site B: n = 8) and 19 Asiatic Clam composite samples (site A: n = 11; site B: n = 8).…”

“…The heptageniid mayfly Maccafertium modestum (Banks) scrapes biofilm from the surface of submerged objects such as wood debris or facultatively collects leaf particles (Kondratieff andVoshell 1980, Merritt et al 2008). A more complete description of these species is provided in Fletcher et al (2014b), which compares the trophic levels and carbon sources between these 2 stream invertebrates.…”

Extensive industrial areas in headwater stream watersheds can severely impact the physical condition of streams and introduce contaminants. We compared 3 streams that received stormwater runoff and industrial effluents from industrial complexes to 2 reference streams. Reference streams provide a benchmark of comparison of geomorphic form and stability in coastal plain, sandy‐bottomed streams as well as concentrations of trace elements in sediment and biota in the absence of industrial disturbance. We used crayfish (Cambarus latimanus, Procambarus raneyi, Procambarus acutus) and crane fly larvae (Tipula) as biomonitors of 15 trace elements entering aquatic food webs. Streams with industrial areas were more scoured, deeply incised, and less stable. Sediment organic matter content broadly correlated to trace element accumulation, but fine sediments and organic matter were scoured from the bottoms of disturbed streams. Trace element concentrations were higher in depositional zones than runs within all streams. Despite contaminant sources in the headwaters, trace element concentrations were generally not elevated in sediments of the eroded streams. However, element concentrations were frequently elevated in biota from these streams with taxonomic differences in accumulation amplified. In eroded, sand‐bottomed coastal plain streams with unstable sediments, single snapshots of sediment trace element concentrations did not characterize well bioavailable trace elements. Biota that integrated exposures over time and space within their home ranges better detected bioavailable contaminants than sediment. Environ Toxicol Chem 2019;38:115–131. © 2018 SETAC

We examined the bioaccumulation of essential (Cu, Fe, Se, and Zn) and nonessential (As and Hg) trace elements in 2 aquatic invertebrate species (adult snails and mayfly nymphs) with different feeding habits at the site of a coal ash spill. Differences in food web pathway, exposure concentrations, and biological processing affected bioaccumulation patterns in these species. Mayflies had higher body burdens, but snails had higher retention of most elements studied.
