When does temperature matter? Response of rice arsenic to heat exposure during different developmental stages
Arsenic is a frequent contaminant of rice. Recent studies show that elevated temperatures, like those from climate change, can further increase arsenic concentrations in rice. It is still unclear if the timing...

Impacts of The Wetland Sedge Carex aquatilis on Microbial Community and Methane Metabolisms
Microbial activity in the soil of wetlands is responsible for the emission of more methane to the atmosphere than all other natural sources combined. This microbial activity is heavily impacted by plant roots,...

Open AccessDiverse sediment microbiota shape methane emission temperature sensitivity in Arctic lakes
Northern post-glacial lakes are significant, increasing sources of atmospheric carbon through ebullition (bubbling) of microbially-produced methane (CH4) from sediments. Ebullitive CH4 flux correlates strongly wi...

The importance of nutrients for microbial priming in a bog rhizosphere
Wetlands host anaerobic microbes which convert organic carbon into methane (CH4), a powerful greenhouse gas. Wetland plants can influence which carbon compounds are available for microbial processing by exuding f...

Open AccessRepresenting the function and sensitivity of coastal interfaces in Earth system models
Between the land and ocean, diverse coastal ecosystems transform, store, and transport material. Across these interfaces, the dynamic exchange of energy and matter is driven by hydrological and hydrodynamic pr...

Plant root exudates increase methane emissions through direct and indirect pathways
The largest natural source of methane (CH4) to the atmosphere is wetlands, which produce 20% to 50% of total global emissions. Vascular plants play a key role regulating wetland CH4 emissions through multiple mec...

Correction to: Diel plant water use and competitive soil cation exchange interact to enhance NH4+ and K+ availability in the rhizosphere
In Table 1 of the original publication, values and units for parameters used to simulate root nutrient uptake (Vmax and Km) were incorrect. Here we present the correct values and units for these parameters.

Open AccessDiel plant water use and competitive soil cation exchange interact to enhance NH4 + and K+ availability in the rhizosphere
Hydro-biogeochemical processes in the rhizosphere regulate nutrient and water availability, and thus ecosystem productivity. We hypothesized that two such processes often neglected in rhizosphere models — diel...

Modeling CH4 and CO2 cycling using porewater stable isotopes in a thermokarst bog in Interior Alaska: results from three conceptual reaction networks
Quantifying rates of microbial carbon transformation in peatlands is essential for gaining mechanistic understanding of the factors that influence methane emissions from these systems, and for predicting how e...

Anthropogenic influences on groundwater arsenic concentrations in Bangladesh
The origin of dissolved arsenic in the Ganges Delta has puzzled researchers ever since the report of widespread arsenic poisoning two decades ago. Today, microbially mediated oxidation of organic carbon is tho...
