Summary Forest health is critical for sustaining ecosystem services like carbon sequestration. Heart rot, a widespread disease in upland northern hardwood forests, may affect greenhouse gas (CO2 and CH4) fluxes, but its impacts remain poorly measured. Using non‐destructive tomography and direct gas flux measurements, we quantified the effects of heart ...

Background Methane (CH4) oxidation driven by soil aerobic methanotrophs demonstrates the capacity of grassland as a CH4 sink. Methods In this study, we compared the oxidation characteristics of atmospheric‐level and elevated concentration (10%) CH4 in a ...

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]
A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

Bubble transport Mechanism: Indications for a gas bubble-mediated inoculation of benthic methanothrophs into the water column [PDF]
Highlights • A new bentho-pelagic transport mechanism of microorganisms is hypothesized • A bubble transport hypothesis was tested using a new gas bubble-collecting device • Bubble-mediated transport rate of methanotrophs was quantified at ...

Abstract While wetlands represent a small fraction (~5%–10%) of the world's land surface, it is estimated that one‐third of wetlands have been lost due to human activities. Wetland habitat loss decreases ecosystem benefits, including improved water quality and climate change mitigation.

Facultative methanotrophs are abundant at terrestrial natural gas seeps [PDF]
Background: Natural gas contains methane and the gaseous alkanes ethane, propane and butane, which collectively influence atmospheric chemistry and cause global warming.

Abstract Tropical hydroelectric reservoirs are recognized hotspots for greenhouse gas emissions, yet the role of submerged forests in these emissions remains poorly understood. In this study, we investigated the contribution of standing dead trees and their associated epixylic biofilms to methane (CH4) and carbon dioxide (CO2) emissions in the ...

Novel copper-containing membrane monooxygenases (CuMMOs) encoded by alkane-utilizing Betaproteobacteria. [PDF]
Copper-containing membrane monooxygenases (CuMMOs) are encoded by xmoCAB(D) gene clusters and catalyze the oxidation of methane, ammonia, or some short-chain alkanes and alkenes.

Abstract Substrates added to peatland soils through anthropogenic disturbance alter carbon cycling and can shift these ecosystems from sinks to sources of atmospheric carbon. Isolating the direct influence these substrates have on peatland carbon cycling can be a challenge in field‐based studies due to interacting effects of vegetation and ...

Constraining Greenhouse Gas Cycling and Emissions in Africa's Largest Humic Lake
Abstract Humic tropical lakes and wetlands are globally important sources of atmospheric greenhouse gases (GHGs). However, mechanistic insight into GHG cycling in such systems remains limited—especially in understudied central Africa. To address this, here we measured high‐, falling‐, and low‐water seasonal concentrations and isotopic compositions of ...
