Distinct temporal diversity profiles for nitrogen cycling genes in a hyporheic microbiome.
Autor: William C Nelson, Emily B Graham, Alex R Crump, Sarah J Fansler, Evan V Arntzen, David W Kennedy, James C Stegen
Publikováno v: PLoS ONE, Vol 15, Iss 1, p e0228165 (2020)
Biodiversity is thought to prevent decline in community function in response to changing environmental conditions through replacement of organisms with similar functional capacity but different optimal growth characteristics. We examined how this con

A novel construct for scaling groundwater–river interactions based on machine-guided hydromorphic classification
Autor: Zhangshuan Hou, Huiying Ren, Christopher J Murray, Xuehang Song, Yilin Fang, Evan V Arntzen, Xingyuan Chen, James C Stegen, Maoyi Huang, Jesus D Gomez-Velez, Zhuoran Duan, William A Perkins, Marshall C Richmond, Timothy D Scheibe
Publikováno v: Environmental Research Letters, Vol 16, Iss 10, p 104016 (2021)
Hydrologic exchange between river channels and adjacent subsurface environments is a key process that influences water quality and ecosystem function in river corridors. Predictive numerical models are needed to understand responses of river corridor

Influences of organic carbon speciation on hyporheic corridor biogeochemistry and microbial ecology
Autor: James C. Stegen, Tim Johnson, James K. Fredrickson, Michael J. Wilkins, Allan E. Konopka, William C. Nelson, Evan V. Arntzen, William B. Chrisler, Rosalie K. Chu, Sarah J. Fansler, Emily B. Graham, David W. Kennedy, Charles T. Resch, Malak Tfaily, John Zachara
Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-11 (2018)
The mechanisms responsible for stimulating biogeochemical activity in the hyporheic corridor (HC) are poorly understood. Here, the authors find that previously unrecognized thermodynamic mechanisms regulated by groundwater-river water mixing may stro

Groundwater–surface water mixing shifts ecological assembly processes and stimulates organic carbon turnover
Autor: James C. Stegen, James K. Fredrickson, Michael J. Wilkins, Allan E. Konopka, William C. Nelson, Evan V. Arntzen, William B. Chrisler, Rosalie K. Chu, Robert E. Danczak, Sarah J. Fansler, David W. Kennedy, Charles T. Resch, Malak Tfaily
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-12 (2016)
Groundwater-surface water mixing zones link critical ecosystem domains, but attendant microbe-biogeochemistry-hydrology interactions are poorly known. Here, the authors show that groundwater-surface water mixing stimulates respiration, alters carbon

Groundwater Inflows to the Columbia River Along the Hanford Reach and Associated Nitrate Concentrations
Autor: Xingyuan Chen, Michael N. Gooseff, V. A. Garayburu-Caruso, Evan V. Arntzen, Abigail Conner
Publikováno v: Frontiers in Water, Vol 3 (2021)
Healthy river ecosystems require the interaction of many physical and biological processes to maintain their status. One physical process supporting biogeochemical cycling is hydrologic exchange (i.e., hydrologic exchange flows, HEFs) between relativ
