  • Combined effects of copper, nickel, and zinc on growth of a freshwater mussel (Villosa iris) in an environmentally relevant context 

    Timpano, Anthony J.; Jones, Jess W.; Beaty, Braven; Hull, Matthew; Soucek, David J.; Zipper, Carl E. (Elsevier, 2022-01)
    Trace metals rarely contaminate freshwaters independently, hence regulatory limits based on single-metal toxicity may be underprotective of aquatic life. This could be especially the case for rare and sensitive fauna like ...

  • Recent advances in understanding the terminal Ediacaran Earth-life system in South China and Arctic Siberia 

    Cui, H.; Kaufman, Alan J.; Xiao, S.; Grazhdankin, D. V.; Peek, S.; Martin, A. J.; Bykova, N. V.; Rogov, V. I.; Liu, X. M.; Zhang, F.; Romaniello, S. J.; Anbar, A. D.; Peng, Y.; Cai, Y.; Schiffbauer, J. D.; Meyer, M.; Gilleaudeau, Geoffrey J.; Plummer, Rebecca E.; Sievers, N. E.; Goderis, S.; Claeys, P. (2019-11-22)
    The terminal Ediacaran contains dramatic changes in biogeochemical cycles, many of which are closely coupled with evolutionary transitions in the corresponding fossil records. Dynamic redox conditions may have caused a ...

  • Abiotic synthesis of graphite in hydrothermal vents 

    Estes, Emily R.; Berti, Debora; Coffey, Nicole R.; Hochella, Michael F. Jr.; Wozniak, Andrew S.; Luther, George W. III (2019-11-15)
    Deciphering the origin, age, and composition of deep marine organic carbon remains a challenge in understanding the dynamics of the marine carbon cycle. In particular, the composition of aged organic carbon and what allows ...
