Reduction–oxidation (redox) reactions underlie essentially all biogeochemical cycles. Like
most soil properties and processes, redox is spatiotemporally heterogeneous. However …

Water resources, including groundwater and prominent rivers worldwide, are under duress
because of excessive contaminant and nutrient loads. To help mitigate this problem, the …

River network is a common form of lotic ecosystems. Variances in river connection modes
would form networks with significantly different structures, and further affect aquatic …

Wildfires naturally occur in many landscapes, however they are undergoing rapid regime
shifts. Despite the emphasis in the literature on the most severe hydrological responses to …

ABSTRACT Candidate Phyla Radiation (CPR) bacteria and nanoarchaea populate most
ecosystems but are rarely detected in soil. We concentrated particles of less than 0.2 μm in …

The Chloroflexi superphylum have been investigated primarily from the perspective of
reductive dehalogenation of toxic compounds, anaerobic photosynthesis and wastewater …

Nitrous oxide (N2O) is a potent ozone‐depleting greenhouse gas produced by incomplete
denitrification. Recent works on riverine N2O emissions focus mainly on contributions from …

Coupled abiotic and biotic processes in the hyporheic zone, where surface water and
groundwater mix, play a critical role in the biogeochemical cycling of carbon, nutrients, and …

Abstract The US Department of Energy's (DOE) Colorado East River Community
Observatory (ER) in the Upper Colorado River Basin was established in 2015 as a …

The interactions between surface water-groundwater (hyporheic) exchange and sediment
lithology influence oxidation–reduction (redox) conditions near river-aquifer interfaces …
