Abstract Droughts are recognized to impact global biogeochemical cycles. However, the implication of desiccation on in-stream carbon (C) cycling is not well understood yet. We subjected sediments from a lowland, organic rich intermittent stream experimental over 9-week-period investigate temporal changes in microbial functional traits relation their redox requirements, dioxide (CO 2 ) and metha...

BACKGROUND Peatland restoration can have several objectives, for example re-establishing the natural habitat, supporting unique biodiversity attributes or re-initiating key biogeochemical processes, which can ultimately lead to a reduction in greenhouse gas (GHG) emissions. Every restoration measure, however, is itself a disturbance to the ecosystem. METHODS Here, we examine an ecosystem shif...

The predicted increases in drought many forest ecosystems may alter soil microbial community diversity and activity, which further depend on tree species richness. Shifts composition activity could engender changes ecosystem function, notably, greenhouse gas emissions C storage. Using soils from mono-specific mixed three-species stands across Europe, we performed a microcosm experiment to test ...

Drought periods are projected to become more severe and more frequent in many European regions. While effects of single strong droughts on plant and microbial carbon (C) dynamics have been studied in some detail, impacts of recurrent drought events are still little understood.We tested whether the legacy of extreme experimental drought affects responses of plant and microbial C and nitrogen (N)...

Soil drying and rewetting (DRW) events are expected to occur at higher frequencies because of alterations in climate patterns. Readily extractable inorganic microbial soil phosphorus (P) pools may be affected due rapid changes water availability. We aimed determine how P dynamics by repeated DRW using a sandy grassland that regularly experiences DRW. In laboratory incubation study, the was expo...

Coffee is an important export product of Ecuador. Producers are challenged by the implementation of regulatory limits for ochratoxin A. Ecuador has four coffee production areas and the potential for mycotoxin contamination varies due to different environmental conditions and cultural differences in harvesting, storage, processing and commercialization. The major contributors to contamination ar...

Interest in manure management and its effects on nitrogen (N) mineralization has increased in recent years. The focus of this research was to investigate the N-mineralization rates of different soil types in Coastal Plain soils and compare them to a soil from Illinois. Soils with and without dairy composted manure addition were subjected to different wetting/drying cycles [constant moisture at ...
