Corn-soybean rotation and fertilization are common practices improving soil fertility and crop yield. Their effects on bacterial community have been extensively studied, yet, few comprehensive studies about the microbial activity, bacterial community and functional groups in a long-term continuous soybean cropping system after corn insertion and fe...

To quantify the transfer of carbon from tree canopies into the belowground, we conducted a pulse‐labelling with 100‐year old trees in a 15‐year‐long irrigation experiment within a naturally dry pine forest. It took four days until new assimilates were allocated from tree canopies to the rhizosphere. One year later, the 13C signal of the three‐hour ...

Funder: Sequoia Parks Conservancy / Funder: Gordon and Betty Moore Foundation; Id: http://dx.doi.org/10.13039/100000936 / The impact of shifting disturbance regimes on soil carbon (C) storage is a key uncertainty in global change research. Wildfires in coniferous forests are becoming more frequent in many regions, potentially causing large C emissi...

Warming is expected to stimulate soil microbial respiration triggering a positive soil carbon-climate feedback loop while a consensus remains elusive regarding the magnitude of this feedback. This is partly due to our limited understanding of the temperature-adaptive response of soil microbial respiration, especially over broad climatic scales. We ...

Páramos, tropical alpine ecosystems, host one of the world’s most diverse alpine floras, account for the largest water reservoirs in the Andes, and some of the largest soil carbon pools worldwide. It is of global importance to understand the future of this extremely carbon-rich ecosystem in a warmer world and its role on global climate feedbacks. T...

As an alternative to clear-cutting, variable-retention harvesting is now standard forest management practice on the coast of British Columbia and in temperate forests globally, due to the benefits associated with maintaining mature forest species and forest structural diversity. Although there is some evidence that variable-retention harvesting, pa...

Terrestrial ecosystems are increasingly enriched with resources such as atmospheric CO2 that limit ecosystem processes. The consequences for ecosystem carbon cycling depend on the feedbacks from other limiting resources and plant community change, which remain poorly understood for soil CO2 efflux, JCO2, a primary carbon flux from the biosphere to ...

Rapid warming and changing precipitation patterns in northern regions are alleviating temperature and nutrient limitations on microbial activity in soils and jeopardizing the stability of vast amounts of ancient organic carbon (C) stored in near-surface permafrost. Like fossil fuels, permafrost C is depleted in radiocarbon (14C) and its emission to...

The effect of climate change on peatlands is of great importance due to their large carbon stocks. In this study, we examined microbial biomass and effect of temperature and O2 availability on soil respiration of surface and subsurface Sphagnum peat. The interactive effect of biotic and abiotic factors significantly affects soil respiration. Increa...

AbstractThe spatiotemporal variability of CO2 emission from soils of Kursk under different land uses, pollution levels, and soil geneses has been assessed. Data on the seasonal dynamics of CO2 emissions in background (forested recreational areas) and urban soils under the anthropogenic impact are presented. Seasonal dynamics of soil СО2 emission de...
