متن کاملLight-Dependent Aerobic Methane Oxidation Reduces Methane Emissions from Seasonally Stratified Lakes
Lakes are a natural source of methane to the atmosphere and contribute significantly to total emissions compared to the oceans. Controls on methane emissions from lake surfaces, particularly biotic processes within anoxic hypolimnia, are only partially understood. Here we investigated biological methane oxidation in the water column of the seasonally stratified Lake Rotsee. A zone of methane ox...
متن کاملOn-Line Measurement of Dissolved Methane Concentration During Methane Fermentation in a Loop Bioreactor
A dissolved methane sensor based on silicone tube was designed, constructed and optimized.The silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.A continuous stream of helium (50 mL/min) was directed through the tubing, sweeping out the...
متن کاملConstraints on methane oxidation in ice-covered boreal lakes
Boreal lakes can be ice covered for a substantial portion of the year at which time methane (CH4) can accumulate below ice. The amount of CH4 emitted at ice melt is partially determined by the interplay between CH4 production and CH4 oxidation, performed by methane-oxidizing bacteria (MOB). Yet the balance between oxidation and emission and the potential for CH4 oxidation in various lakes durin...
متن کاملAnaerobic methane oxidation and denitrification as methane sink
Early social exposure is important for developing appropriate, species-specific adult behaviors. Carson Murray et al. (pp. 18189–18194) followed wild chimpanzees, habituated to human observers, in Gombe National Park, Tanzania, and analyzed maternal subgrouping patterns to investigate why adult males tend to be more gregarious than adult females. Mothers accompanied by their sons were more greg...
