Nitrogen isotopic (δ 15N) tissue values of C. fluminea and E. complanata were significantly higher in an agricultural land-use stream site compared to urban and forested samples (p < 0.05). Nitrogen (δ 15N) tissue values for both species were significantly (p < 0.001) associated with land-use type or patterns. The potential use of resident, non-native bivalves as biomonitors of potentially harmful nitrogen levels was implied.}, number={1}, journal={Journal of Freshwater Ecology}, publisher={Informa UK Limited}, author={Bucci, John P. and Levine, Jay F. and Showers, William J.}, year={2011}, month={Mar}, pages={19–24} } @article{bucci_showers_genna_levine_2009, title={Stable oxygen and carbon isotope profiles in an invasive bivalve (Corbicula fluminea) in North Carolina watersheds}, volume={73}, ISSN={0016-7037}, url={http://dx.doi.org/10.1016/j.gca.2009.03.023}, DOI={10.1016/j.gca.2009.03.023}, abstractNote={The modern invasive bivalve Corbicula fluminea was collected in 2006 from three sites with different land uses located in a North Carolina River Basin. The primary objective was to describe the δ18O and δ13C profiles of C. fluminea shells under various land use conditions. An additional aim was to evaluate whether growth patterns of C. fluminea form seasonally. Annual shell growth patterns were measured from the umbo to the margin and co-varied with estimates of ambient water temperature, corresponding to seasonal variation. The C. fluminea growth patterns as translucent bands (slower growth) appeared to form during winter months and opaque bands (rapid growth) formed during summer. A mixed model analysis (ANOVA) showed a significant site level effect of δ18O and δ13C profiles examined among sites (F = 17.1; p = 0.003). A second model showed a borderline significant site effect among profiles with variability more pronounced at the urban site, Crabtree Creek (p = 0.085). Previous habitat assessment ratings and water chemistry measurements suggested that the urban site was more impacted by storm water runoff. Understanding δ18O and δ13CSHELL profiles and shell growth patterns of the invasive bivalve (C. fluminea) may help establish a framework for using these animals as biomonitors to record water temperature and nutrient pollution.}, number={11}, journal={Geochimica et Cosmochimica Acta}, publisher={Elsevier BV}, author={Bucci, John P. and Showers, William J. and Genna, Bernie and Levine, Jay F.}, year={2009}, month={Jun}, pages={3234–3247} } @article{bucci_2009, title={Stable oxygen and carbon isotope profiles in an invasive bivalve (Corbicula fluminea) in North Carolina watersheds (vol 73, pg 3234, 2009)}, volume={73}, number={16}, journal={Geochimica et Cosmochimica Acta}, author={Bucci, J.

Bivalves collected from a nutrient sensitive estuary yielded a significant difference in mean nitrogen isotopic composition of tissue (10.4 per thousand+/-0.82; N=66) compared to bivalves collected from a less nutrient sensitive estuary (6.4 per thousand+/-0.63; N=45). Similarly, blue crabs from nutrient sensitive sites had a nitrogen isotopic composition of 11.4 per thousand (+/-1.3, N=77), which was significantly different (P<0.001) than the tissue of less nutrient sensitive blue crabs (9.6 per thousand+/-0.6; N=77). The results showed that an inverse relationship exists between invertebrate tissue enrichment and indicators of water quality across estuarine sites. This study suggests that a relationship may exist between nutrient sources and subsequent energy transfer to estuarine consumers in two North Carolina estuaries.}, number={1}, journal={Environmental Pollution}, author={Bucci, J.
