“…As noted in Section 3.1, SRS's terrestrial habitat is primarily comprised of forestland. However, over 20 percent of the SRS's surface area is covered by water, including wetlands, bottomland hardwoods, cypress-tupelo swamp forests, two large cooling water reservoirs (PAR Pond and L Lake), creeks and streams, and over 300 isolated upland Carolina Bays and wetland depressions (Davis and Janecek 1997;. The areas into which the subject outfalls discharge are generally dominated by lowland mixed pine-hardwood and bottomland forests.…”

A-11 Smooth purple coneflower is not known to occur in the vicinity of the 38 project areas and no suitable habitat was identified during field surveys. Therefore no impact to smooth purple coneflower is expected as a result of activities associated with project implementation.. 5.0 DETERMINATION OF EFFECTS SUMMARY No Effect: No long-term effect is expected on the smooth purple coneflower, pondberry, red-cockaded woodpecker, American alligator, bald eagle, shortnose sturgeon, or wood stork populations within the selected project areas or on a site-wide level.

“…For this study animals from all sites were treated together. The SRS sites were chosen to include some sites contaminated with 137 Cs and other radionuclides (Pond B, Steel Creek), sites contaminated with metals (near a coal-fired power plant), and sites that are normally considered reference sites (Dry Bay, Upper Three Runs Creek) (Davis & Janecek, 1997). Off-site locations were public hunting grounds located 8 km west-northwest of the town of Jackson, SC, 15 km northwest of SRS and 3 km south of SRS ( Figure 1).…”

“…Dry Bay (5 ha), a Carolina bay that has a seasonally variable water level (Semlitsch et al, 1996), and Upper Three Runs have been used as reference sites for other SRS studies, and they have received little impact from SRS operations (Davis & Janecek, 1997). The off-site raccoons were collected in lowland, swampy, public lands where raccoons are hunted.…”

The relationship between metallothionein levels and concentrations of several metals and radionuclides was examined in liver tissues of raccoons (Procyon lotor, n = 47) from the Department of Energy's Savannah River Site in South Carolina to determine the applicability of metallothioneins as an initial screening device for exposure assessment in free-living mammals and environmental monitoring. Using a fluorescent marker and a cell sorter to measure metallothionein, a significant positive correlation was found across animals between levels of metallothioneins and concentrations of selenium (Pearson's r = .30), mercury (Pearson's r = .3 1), and copper (Pearson's r = .30) in liver tissue. Arsenic, cobalt, silver, thallium, and tin were below detection limits in most or all liver samples. Other metals, including cadmium, chromium, radiocesium (137-Cs), copper, lead, manganese, strontium, and vanadium, showed only weak and nonsignificant correlations with metallothionein. Concentrations of mercury were correlated with concentrations of selenium (Pearson's r = .73), manganese (Pearson's r = .56), and strontium (Pearson's r = .57). In an a posteriori test, there was a still unexplained positive correlation between mercury (Pearson r = .56), selenium (Pearson r = .54), and radiocesium (Pearson's r = .38) concentrations and background cellular autofluorescence, and a negative correlation of strontium with the latter (Kendall tau = -.38). Background cellular autofluorescence may represent a generalized cellular stress response, or a yet unidentified biomarker. To better understand which metals contribute to the induction of metallothionein, principle component analysis (PCA) was performed. The first three principle components explained 78% of the variance, with highest loadings being from mercury and radiocesium. Metallothionein levels did not correlate well with the principal components from the metals and radiocesium, while autofluorescent background levels tended to correlate better.

“…Rainbow Bay is found at c. 97 m elevation on the Aiken Plateau, whereas GB occurs on an old Pleistocene floodplain terrace of the Savannah River (Sunderland Terrace) at 61 m elevation. Both wetlands are surrounded by well-drained sandy loam soils in the Fuquay and Dothan series, but wetlands themselves are located on poorly drained sandy fine loam soils (Davis & Janecek, 1997). Wetland soils also differ in elemental composition from surrounding upland soils as depressional wetland soils on the SRS tend to have elevated aluminium (Al) and barium (Ba) concentrations and total N, P and C levels compared to upland soils (Dixon et al, 1997;Looney et al, 1990).…”

Understanding variation in salamander ionomes: A nutrient balance approach

et al. 2018

Ecological stoichiometry uses information on a few key biological elements (C, N and P) to explain complex ecological patterns. Although factors driving variation in these elements are well established, expanding stoichiometric principles to explore dynamics of the many other essential elements comprising biological tissues (i.e. the ionome) is needed to determine their metabolic relationships and better understand biological control of elemental flows through ecosystems. In this paper, we report observations of ionomic variation in two species of salamander (Ambystoma opacum and A. talpoideum) across ontogenic stages using specimens from biological collections of two wetlands sampled over a 30‐year period. This unique data set allowed us to explore the extent of ionomic variation between species, among ontogenic stages, between sites and through time. We found species‐ and, to a lesser extent, site‐specific differences in C, N and P along with 13 other elements forming salamander ionomes but saw no evidence of temporal changes. Salamander ionomic composition was most strongly related to ontogeny with relatively higher concentrations of many elements in adult males (i.e. Ca, P, S, Mg, Zn and Cu) compared to metamorphic juveniles, which had greater amounts of C, Fe and Mn. In addition to patterns of individual elements, covariance among elements was used to construct multi‐elemental nutrient balances, which revealed differences in salamander elemental composition between species and sites and changes in elemental proportions across ontogenic development. These multi‐elemental balances distinguished among species‐site‐ontogenic stage groups better than using only C, N and P. Overall, this study highlights the responsiveness of consumer ionomes to life‐history and environmental variation while reflecting underlying relationships among elements tied to biological function. As such, ionomic studies can provide important insights into factors shaping consumer elemental composition and for predicting how these changes might affect higher‐order ecological processes.
