Soil carbon concentration drives anoxic microsites across horizons, textures, and aggregate position in a California grassland

Anoxic microsites, zones of oxygen depletion in otherwise well-aerated soils, serve as prominent controls on several biogeochemical cycles (e.g., carbon, nitrogen, iron). However, relatively little is known about the spatiotemporal distribution of anoxic m ...

Climate change impacts on organic carbon cycling in European alpine soils

Meret Aeppli

This review focuses on impacts of climate change on soil organic carbon (SOC) cycling in alpine soils, with a specific emphasis on input and loss processes. In alpine regions, low temperatures and variable snow cover govern plant productivity and microbial ...

X-ray chemical imaging for assessing redox microsites within soils and sediments

Meret Aeppli, Vincent Noel

Redox reactions underlie several biogeochemical processes and are typically spatiotemporally heterogeneous in soils and sediments. However, redox heterogeneity has yet to be incorporated into mainstream conceptualizations and modeling of soil biogeochemist ...

Resilience of aerobic methanotrophs in soils; spotlight on the methane sink under agriculture

Meret Aeppli, Wenyu Gu

Aerobic methanotrophs are a specialized microbial group, catalyzing the oxidation of methane. Disturbance-induced loss of methanotroph diversity/abundance, thus results in the loss of this biological methane sink. Here, we synthesized and conceptualized th ...

Iron Reduction in Profundal Sediments of Ultraoligotrophic Lake Tahoe under Oxygen-Limited Conditions

Meret Aeppli

Increased periods of bottom water anoxia in deep temperate lakes due to decreasing frequency and depth of water column mixing in a warming climate may result in the reductive dissolution of iron minerals and increased flux of nutrients from the sediment in ...

Consider the Anoxic Microsite: Acknowledging and Appreciating Spatiotemporal Redox Heterogeneity in Soils and Sediments

Meret Aeppli, Vincent Noel

Reduction-oxidation (redox) reactions underlie essentially all biogeochemical cycles. Like most soil properties and processes, redox is spatiotemporally heterogeneous. However, unlike other soil features, redox heterogeneity has yet to be incorporated into ...

Assessing Analytical Methods for the Rapid Detection of Lead Adulteration in the Global Spice Market

Meret Aeppli

Lead adulteration of spices, primarily via Pb chromate compounds, has been documented globally as a growing public health concern. Currently, Pb detection in spices relies primarily on expensive and time-consuming laboratory analyses. Advancing rapid Pb de ...
