Summary: Drying-rewetting cycles can alter the structure and heavy metal adsorption capacity of biofilms. The adsorption capacity of Cd2+ and Pb2+ decreased with increasing cycles, while the tolerance to these metals increased. The stress from the cycles may have caused changes in the composition of the biofilm, leading to altered functions and metal adsorption capacity.

Summary: The impact of drying-rewetting cycles on the behavior of differently-sized colloidal phosphorus in agricultural soils is significant. The fine-sized colloidal phosphorus dominates the overall distribution of colloidal phosphorus. Drying-rewetting cycles do not change the distribution of phosphorus size fractions, but they affect the concentration and composition of phosphorus.

Summary: This study conducted a reciprocal-transplant experiment to investigate the effects of microbial communities on soil respiration and its resilience to drying and rewetting cycles. Results showed that microbial communities played a significant role in regulating soil respiration and resilience, with a dependence on soil type. Soil pH and total C directly influenced soil respiration, while microbial communities mediated the effects of soil abiotic properties on respiration resilience. The study suggests that soil microbial communities may have adapted to historical conditions, facilitating soil respiration resilience, but potentially accelerating carbon loss in soils facing variable climates.

Summary: The drying-rewetting cycles in paddy soils have a significant impact on ferrous iron-involved denitrification process, leading to a decrease in denitrification rate and accumulation of ammonia nitrogen during the drying period. Organic carbon plays a dual role in providing electron donors to denitrification and reducing ferric iron during the rewetting period. Complex interactions exist among organic carbon, nitrate, and Fe2+/Fe3+ under drying-rewetting cycles, with soil rewetting triggering denitrification flush, especially after a moderately long drying period.

Summary: Our study found that exposure to repeated DRW cycles shifted bacterial growth response from type 2 to type 1 pattern, accelerating the recovery rate; soils with initial type 1 response tended to recover faster after each subsequent DRW cycle; repeated DRW cycles shaped the bacterial response to future DRW cycles, possibly mediated by a shift in species composition, physiological adjustment, evolutionary changes, or a combination of the three.

Summary: This study investigated the effect of biochar addition on colloidal phosphorus (P-coll) content and its associated microbial communities and phosphatase activities during drying and rewetting cycles. The results showed that biochar significantly reduced P-coll content and increased phosphatase-producing microbial communities and phosphatase activities. This research provides a novel understanding of how biochar reduces P-coll loss by regulating microbial communities during drying and rewetting events.

Summary: This study investigated the effects of DWCs on soil properties and microorganisms. The results showed significant differences in cumulative CO2 emissions among different DWC frequencies in woodland soils. The Birch effect was found to be correlated with DWC frequencies, and background nutrient contents were identified as key factors influencing alpha diversity.

Summary: The study found that climate change can increase the impact of drying-wetting cycles on soil microbial biomass carbon and dissolved organic carbon. Soil MBC increases with the number of drying-wetting cycles, while soil DOC decreases with the number of drying-wetting cycles.

Summary: Climate change intensifies the drying-rewetting alternation disturbance, which has negative impacts on soil ecosystem function and agriculture production. This study investigated the effects of intercropping green manure on soil multifunctional resistance to drying-rewetting cycles in tea plantation. The results showed that intercropping soybean and soybean + milk vetch significantly increased multifunctionality resistance compared to monoculture. The abundance of functional genes was found to be the major driver of multifunctionality resistance.

Summary: This study investigated the impact of silicon fertilization on decomposition in wetlands during drying-rewetting cycles. The results showed that silicon fertilization increased CH4 production, improved plant viability and produced more readily decomposable litter. This may lead to increased methane emissions from the soil into the atmosphere.

Summary: The study focused on the impact of rapid rewetting and slow rewetting of dry soil on soil respiration and nutrient cycling. Results showed that slow rewetting can increase the flush of respiration, but only if the second partial rewetting occurs 6 hours after the first.

Summary: Global climate change is expected to increase the frequency of drought and heavy precipitation, leading to more frequent drying-rewetting cycles in soils. The effects of these cycles on soil organic carbon (SOC) decomposition and the subsequent legacy effect on different SOC pools are still unclear.

Summary: Microbial lipids and metabolites in the soil play a critical role in regulating the microbial response to stress, especially during drying-rewetting cycles. This study revealed specific changes in lipids and metabolites that are indicative of stress adaptation, substrate use, and cellular recovery during soil drying and subsequent rewetting. The results underscore the importance of the soil lipidome as a robust indicator of microbial community responses.

Summary: Hypoxia, a condition with low dissolved oxygen levels, is an important indicator of freshwater ecosystem health. However, knowledge about the extent, distribution, and timing of hypoxia events in headwater networks is limited. This study used three years of instrumentation at 78 sites in eight temperate, agricultural watersheds to investigate hypoxia. The findings showed that hypoxia was broadly distributed and occurred 4% of the time across 51 of the 78 sites over 20 months. The main drivers of hypoxia were storm events, drying, and rewetting.

Summary: Climate change alters frequencies and intensities of soil drying-rewetting and freezing-thawing cycles, impacting soil water availability crucial for microbial activity. Experiments show that drying-rewetting cycles have stronger effects on soil microbial communities and CO2 production than freezing-thawing cycles.

Summary: The study on Italy's secondary sex ratio (SSR) revealed two marked level shifts at the end of the 1960s and from 1987 onward, following the release of radioactivity by atmospheric atomic bomb tests during the 1960s and by Chernobyl in 1986. These shifts support the hypothesis that ionizing radiation increases SSR.

Summary: Trisomy 21 (Down syndrome) is the most common autosomal aneuploidy among newborns, primarily caused by meiotic nondisjunction during oogenesis. The identification of environmental factors and their effects on the prevalence of Down syndrome is challenging due to various factors. Monitoring trisomy 21 through epidemiological studies provides insights into risk avoidance, preventive measures, and identification of genomic variants involved in chromosomal nondisjunction.

Summary: Malta experienced a significant decline in healthcare services during the COVID-19 pandemic, although the rollout of vaccination led to a decrease in COVID-19 hospital admissions. Delayed or deferred medical management may increase population morbidity and mortality, and burden the healthcare system.
