Abstract:
... Vesicular pores are observed in many different soil-forming environments. They can also be re-created in the lab through exposure to cyclic wetting and drying. However, little is known about the physical, chemical, and biological mechanisms involved in vesicular pore formation. This study was conducted to test the hypotheses that 1) microbial activity and 2) thermal expansion are important drivers ...

Abstract:
... The discovery of antibiotics in the twentieth century made it possible to treat bacterial infections and revolutionized modern medicine. However, gradually, it is possible to perceive a decrease in the effectiveness of antimicrobial agents against pathogenic isolates, which, together with the low investment in the discovery and/or development of new antibiotics by large pharmaceutical companies si ...

Abstract:
... Over the last decades, a new generation of microscale models has been developed to simulate soil microbial activity. An earlier article (Pot et al., 2021) presented a detailed review of the description of soil architecture and microbial dynamics in these models. In the present article, we summarise the main results obtained by these models according to six model outputs: growth and spatial organis ...

Abstract:
... AIMS: The rhizosphere and root detritusphere are hotspots of microbial activity, where root-derived inputs induce intensive priming effects (PE) on soil organic carbon (SOC) decomposition. These conditions for induced PE differ between rhizosphere and detritusphere and are modified by plant traits. METHODS: Continuous labelling with ¹³C-depleted CO₂ allowed for the partitioning of plant and soil C ...

Abstract:
... Salinity and soil organic matter (SOM) are key edaphic factors that exert substantial influence on soil microbial activity. To understand the interactive effects of both factors on microbial activity, nine ecoenzymes involved in C, N, P and S cycling were assayed across a saline gradient (coastal areas of the Bohai Gulf, CN). The electrical conductivity (EC) of the soils ranged from 0.14 to 13.65 ...

Abstract:
... Wetland ecosystems have low plant diversity, dominated only by one or two types of vegetation. Species with high biomass can easily invade wetlands and the effect of plant invasion on ecosystem process rates has drawn considerable attention within the field of microbial ecology. However, the effects of high biomass plants on microbes, which play a central role in wetland biogeochemistry, are notab ...

Abstract:
... N₂O, a greenhouse gas, is increasingly emitted from degrading permafrost mounds of palsa mires because of the global warming effects on microbial activity. In the present study, we hypothesized that N₂O emission could be affected by a change in pH conditions because the collapse of acidic palsa mounds (pH 3.4–4.6) may result in contact with minerogenic ground water (pH 4.8–6.3), thereby increasing ...

PURPOSE: Global climate change scenarios forecast the increasing frequency of extreme precipitation events in the Qinghai-Tibet Plateau (QTP), events that likely will result in increased annual rainfall. The effects of varying rainfall frequency on terrestrial ecosystems, especially in QTP regions impacted by global warming, have become a major research topic. However, the responses of soil labile ...
