Temporal dynamics of nitrogen cycle gene diversity in a hyporheic microbiome

W. C. Nelson, E. B. Graham, A. R. Crump, S. J. Fansler, E. V. Arntzen, D. W. Kennedy, J. C. Stegen

The paper examines seasonal changes in within-gene diversity for nitrogen cycling genes in hyporheic zone communities, finding that nitrification genes show low richness while denitrification genes vary in richness and phylotype turnover.

Dispersal limitation and thermodynamic constraints govern spatial structure of permafrost microbial communities

E. M. Bottos, D. W. Kennedy, E. B. Romero, S. J. Fansler, J. M. Brown, L. M. Bramer, R. K. Chu, M. M. Tfaily, J. K. Jansson, J. C. Stegen

This study identifies dispersal limitation and thermodynamic constraints as key factors shaping permafrost microbial community structure, distinct from non-permafrost soils.

Carbon inputs from riparian vegetation limit oxidation of physically-bound organic carbon via biochemical and thermodynamic processes

E. B. Graham, M. Tfaily, A. R. Crump, A. E. Goldman, L. Bramer, E. Arntzen, E. Romero, C. T. Resch, D. W. Kennedy, J. C. Stegen

The paper investigates how riparian vegetation affects oxidation of physically-bound organic carbon through biochemical and thermodynamic processes in the Columbia River corridor.

Deterministic influences exceed dispersal effects on hydrologically-connected microbiomes

E. B. Graham, A. R. Crump, C. T. Resch, S. Fansler, E. Arntzen, D. W. Kennedy, J. K. Fredrickson, J. C. Stegen

The paper investigates microbiome assembly in hydrologically-connected zones, finding deterministic ecological selection over dispersal and identifying organism groups linked to seasonal metabolic shifts in hyporheic zones.
