Nutrient Inputs Stimulate Mercury Methylation by Syntrophs in a Subarctic Peatland

Autor: Spencer Roth, Brett A. Poulin, Zofia Baumann, Xiao Liu, Lin Zhang, David P. Krabbenhoft, Mark E. Hines, Jeffra K. Schaefer, Tamar Barkay

Publikováno v: Frontiers in Microbiology, Vol 12 (2021)

Climate change dramatically impacts Arctic and subarctic regions, inducing shifts in wetland nutrient regimes as a consequence of thawing permafrost. Altered hydrological regimes may drive changes in the dynamics of microbial mercury (Hg) methylation

Elevated temperature alters microbial communities, but not decomposition rates, during three years of in-situ peat decomposition

Autor: Spencer Roth, Natalie A. Griffiths, Randall K. Kolka, Keith C. Oleheiser, Alyssa A. Carrell, Dawn M. Klingeman, Angela Seibert, Jeffrey P. Chanton, Paul J. Hanson, Christopher W. Schadt

Peatlands store approximately one-third of the global terrestrial carbon and are historically considered carbon sinks due to primary production outpacing microbial decomposition of organic matter. Climate change has the potential to alter the rate at

Temporal variation in skin microbiota of cohabitating amphibians

Autor: Ariel Kruger, Spencer Roth

Publikováno v: Canadian journal of microbiology. 68(9)

Temporal changes and transmission patterns in host-associated microbial communities have important implications for host health. The diversity of amphibian skin microbial communities is associated with disease outcome in amphibians exposed to the fun

Characterizing and Evaluating the Diverse Microbial Communities and Their Mercury Resistance Potential from Hot Spring Sites Representing Gradients in Temperature and pH in Yellowstone National Park

Autor: Spencer Roth, Tamar Barkay, Yelizaveta Rassadkina

Publikováno v: Aresty Rutgers Undergraduate Research Journal. 1

Yellowstone National Park is home to many different hot springs, lakes, geysers, pools, and basins that range in pH, chemical composition, and temperature. These different environmental variations provide a broad range of conditions that select and g

Production of methylmercury by methanogens in mercury contaminated estuarine sediments

Autor: Jeffra K. Schaefer, Nathan Yee, John R. Reinfelder, Yuwei Wang, Spencer Roth

Publikováno v: FEMS Microbiology Letters. 367

Anaerobic bacteria are known to produce neurotoxic methylmercury [MeHg] when elemental mercury [Hg(0)] is provided as the sole mercury source. In this study, we examined the formation of MeHg in anaerobic incubations of sediment collected from the Sa

The role of oxygen in stimulating methane production in wetlands

Autor: Jared L. Wilmoth, Spencer Roth, Patrick G. Hatcher, Julie K. Shoemaker, Jeffra K. Schaefer, Xinning Zhang, Danielle R. Schlesinger

Publikováno v: Global change biology. 27(22)

Methane (CH4 ), a potent greenhouse gas, is the second most important greenhouse gas contributor to climate change after carbon dioxide (CO2 ). The biological emissions of CH4 from wetlands are a major uncertainty in CH4 budgets. Microbial methanogen
