“…These results did not support our first hypothesis that warming would reduce soil fungal richness. Our results are not consistent with previous results obtained in a temperate desert steppe ( Jia et al, 2023 ) and cold alpine grasslands ( Qi et al, 2021 ) but are consistent with the results in the Northern Tibet alpine meadow ( Yu CQ, et al, 2019 ) and in a Mediterranean shrubland ( Birnbaum et al, 2019 ). The results suggest that warming might stimulate the growth of fungi in the lower temperature meadow ecosystem because in comparison to other species, the dominant species Leymus chinensis is a perennial that has a long-lived root system that responds more slowly to environmental changes and thus can retain soil fungal diversity.…”

“…Previous results from a Tibetan alpine meadow showed that warming increased soil bacterial diversity ( Li et al, 2016 ; Yu CQ, et al, 2019 ), but other studies found that warming did not affect soil bacterial diversity ( Zi et al, 2018 ; Qi et al, 2021 ). In the present study, warming significantly reduced the diversity of soil bacteria, which is consistent with a previous result from a desert steppe in northern China ( Jia et al, 2023 ). The results suggest that the response of soil bacteria is not consistent.…”

Soil microbial communities have been influenced by global changes, which might negatively regulate aboveground communities and affect nutrient resource cycling. However, the influence of warming and nitrogen (N) addition and their combined effects on soil microbial community composition and structure are still not well understood. To explore the effect of warming and N addition on the composition and structure of soil microbial communities, a five-year field experiment was conducted in a temperate meadow. We examined the responses of soil fungal and bacterial community compositions and structures to warming and N addition using ITS gene and 16S rRNA gene MiSeq sequencing methods, respectively. Warming and N addition not only increased the diversity of soil fungal species but also affected the soil fungal community structure. Warming and N addition caused significant declines in soil bacterial richness but had few impacts on bacterial community structure. The changes in plant species richness affected the soil fungal community structure, while the changes in plant cover also affected the bacterial community structure. The response of the soil bacterial community structure to warming and N addition was lower than that of the fungal community structure. Our results highlight that the influence of global changes on soil fungal and bacterial community structures might be different, and which also might be determined, to some extent, by plant community, soil physicochemical properties, and climate characteristics at the regional scale.

“…A study has indicated a more sensitive bacterial rate in the air of healthcare settings compared to fungi [ 51 ]. In soil ecosystems, bacterial communities also have been demonstrated to be more sensitive than fungal communities to changes in soil properties [ 50 , 52 ]. This might be partially explained by the difference in cell walls between bacteria and fungi.…”

Airborne microorganisms, including pathogens, would change with surrounding environments and become issues of global concern due to their threats to human health. Microbial communities typically contain a few abundant but many rare species. However, how the airborne abundant and rare microbial communities respond to environmental changes is still unclear, especially at hour scale. Here, we used a sequencing approach based on bacterial 16S rRNA genes and fungal ITS2 regions to investigate the high time‐resolved dynamics of airborne bacteria and fungi and to explore the responses of abundant and rare microbes to the atmospheric changes. Our results showed that air pollutants and microbial communities were significantly affected by human activities related to the Chinese New Year (CNY). Before CNY, significant hour‐scale changes in both abundant and rare subcommunities were observed, while only abundant bacterial subcommunity changed with hour time series during CNY. Air pollutants and meteorological parameters explained 61.5%−74.2% variations of abundant community but only 13.3%−21.6% variations of rare communities. These results suggested that abundant species were more sensitive to environmental changes than rare taxa. Stochastic processes predominated in the assembly of abundant communities, but deterministic processes determined the assembly of rare communities. Potential bacterial pathogens during CNY were the highest, suggesting an increased health risk of airborne microbes during CNY. Overall, our findings highlighted the “holiday effect” of CNY on airborne microbes and expanded the current understanding of the ecological mechanisms and health risks of microbes in a changing atmosphere.

“…To date, the responses of soil microbial communities (Castro et al, 2010 ; Zhou et al, 2020 , 2023 ; Abs et al, 2023 ; Baldrian et al, 2023 ; Cruz-Paredes et al, 2023 ; Hu et al, 2023 ; Jansson and Wu, 2023 ; Jia et al, 2023 ; Meena et al, 2023 ) and/or soil microarthropods (Liu et al, 2020 ; Meehan et al, 2020 ; Barreto et al, 2023 ; Thakur et al, 2023 ) have been intensively studied. As suggested, the interactions between soil microorganisms and soil invertebrates include direct predator-prey relationships, but also indirect effects, such as competition for resources and habitat formation (Scheu et al, 2005 ).…”
