Linking microbial community structure and microbial processes: an empirical and conceptual overview
A major goal of microbial ecology is to identify links between microbial community structure
and microbial processes. Although this objective seems straightforward, there are conceptual …

Understanding how microbiomes influence the systems they inhabit
Translating the ever-increasing wealth of information on microbiomes (environment, host or
built environment) to advance our understanding of system-level processes is proving to be …

Bacterial community responses to a gradient of alkaline mountaintop mine drainage in Central Appalachian streams
Microbial community composition and diversity change along chemical gradients, leading to
the expectation that microbial community information might provide new gradient …

In search of microbial indicator taxa: shifts in stream bacterial communities along an urbanization gradient
A majority of environmental studies describe microbiomes at coarse scales of taxonomic
resolution (bacterial community, phylum), ignoring key ecological knowledge gained from finer‐…

Auxotrophic interactions: a stabilizing attribute of aquatic microbial communities?
Auxotrophy, or an organism's requirement for an exogenous source of an organic molecule,
is widespread throughout species and ecosystems. Auxotrophy can result in obligate …

[HTML][HTML] Biofilm mediated uptake of selenium in streams with mountaintop coal mine drainage
MC Arnold, RL Bier, TT Lindberg, ES Bernhardt… - Limnologica, 2017 - Elsevier
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 …

Agricultural soil microbiomes differentiate in soil profiles with fertility source, tillage, and cover crops
Soil microbiota are critical to soil health, yet a substantial knowledge gap remains to
understand how microbial communities can be interpreted as soil health parameters and, …

Bacterial communities and nitrogen transformation genes in streambank legacy sediments and implications for biogeochemical processing
N Sienkiewicz, RL Bier, J Wang, L Zgleszewski… - Biogeochemistry, 2020 - Springer
Streambank legacy sediments may be important sources of sediment and nutrients from Mid-Atlantic
watersheds. However, little is known about the nutrient processing roles of …
