Biofilm mediated uptake of selenium in streams with mountaintop coal mine drainage

Autor: Raven L. Bier, R. T. Di Giulio, M. C. Arnold, Emily S. Bernhardt, T. Ty Lindberg

Publikováno v: Limnologica. 65:10-13

Selenium (Se) may cause reproductive toxicity, yet the characteristics of Se bioaccumulation in aquatic food webs are understudied. Stream biofilms were grown in two reaches of Mud River, West Virginia (WV), including one downstream of a coal mine co

Antioxidant Rescue of Selenomethionine-Induced Teratogenesis in Zebrafish Embryos

Autor: R. T. Di Giulio, Jordan E Forte, M. C. Arnold, Joshua S. Osterberg

Publikováno v: Archives of Environmental Contamination and Toxicology. 70:311-320

Selenium (Se) is an essential micronutrient that can be found at toxic concentrations in surface waters contaminated by runoff from agriculture and coal mining. Zebrafish (Danio rerio) embryos were exposed to aqueous Se in the form of selenate, selen

Publikováno v: Biology and Fertility of Soils. 52:177-189

Microbial nutrient limitation was investigated in a 53-year-old field experiment in the Central-West of Burkina Faso under sorghum–cowpea rotation, comparing three fertilization practices: mineral fertilizer (MIN), mineral fertilizer and farmyard m

Microchemical analysis of selenium in otoliths of two West Virginia fishes captured near mountaintop removal coal mining operations

Autor: Lisa A. Friedrich, Norman M. Halden, M. C. Arnold, Vince P. Palace, Richard T. Di Giulio, Emily S. Bernhardt, Matthew R. V. Ross, T. Ty Lindberg

Publikováno v: Environmental Toxicology and Chemistry. 34:1039-1044

Otoliths, calcified inner ear structures, were collected from creek chubs (Semotilus atromaculatus) and green sunfish (Lepomis cyanellus) living in mountaintop mining-impacted and reference streams and analyzed for selenium (Se) content using laser a

International audience; The influence of salinity on Ag toxicity was investigated in Atlantic killifish (Fundulus heteroclitus) early life-stages. Embryo mortality was significantly reduced as salinity increased and Ag+ was converted to AgCl(solid).

High-Throughput Tissue Bioenergetics Analysis Reveals Identical Metabolic Allometric Scaling for Teleost Hearts and Whole Organisms

Autor: Nishad Jayasundara, Jordan S. Kozal, Sherine S.L. Chan, Richard T. Di Giulio, M. C. Arnold

PLoS ONE

Organismal metabolic rate, a fundamental metric in biology, demonstrates an allometric scaling relationship with body size. Fractal-like vascular distribution networks of biological systems are proposed to underlie metabolic rate allometric scaling l
