“…These results again suggest the importance of precipitation as a main climatic driver of soil fungal diversity and community structure (as shown by the CCA results), while prokaryotic communities are more vulnerable to extreme temperature shifts. These results also suggest that in future climate change scenarios, fungal communities across sub-Saharan soils will be more resilient to anthropogenic-driven climate disruptions, a conclusion that is consistent with recent research showing increased resilience of fungal communities to climate change in different parts of the world [119,120].…”

Background Top-soil microbiomes make a vital contribution to the Earth’s ecology and harbor an extraordinarily high biodiversity. They are also key players in many ecosystem services, particularly in arid regions of the globe such as the African continent. While several recent studies have documented patterns in global soil microbial ecology, these are largely biased towards widely studied regions and rely on models to interpolate the microbial diversity of other regions where there is low data coverage. This is the case for sub-Saharan Africa, where the number of regional microbial studies is very low in comparison to other continents. Results The aim of this study was to conduct an extensive biogeographical survey of sub-Saharan Africa’s top-soil microbiomes, with a specific focus on investigating the environmental drivers of microbial ecology across the region. In this study, we sampled 810 sample sites across 9 sub-Saharan African countries and used taxonomic barcoding to profile the microbial ecology of these regions. Our results showed that the sub-Saharan nations included in the study harbor qualitatively distinguishable soil microbiomes. In addition, using soil chemistry and climatic data extracted from the same sites, we demonstrated that the top-soil microbiome is shaped by a broad range of environmental factors, most notably pH, precipitation, and temperature. Through the use of structural equation modeling, we also developed a model to predict how soil microbial biodiversity in sub-Saharan Africa might be affected by future climate change scenarios. This model predicted that the soil microbial biodiversity of countries such as Kenya will be negatively affected by increased temperatures and decreased precipitation, while the fungal biodiversity of Benin will benefit from the increase in annual precipitation. Conclusion This study represents the most extensive biogeographical survey of sub-Saharan top-soil microbiomes to date. Importantly, this study has allowed us to identify countries in sub-Saharan Africa that might be particularly vulnerable to losses in soil microbial ecology and productivity due to climate change. Considering the reliance of many economies in the region on rain-fed agriculture, this study provides crucial information to support conservation efforts in the countries that will be most heavily impacted by climate change.

“…Flooded paddy is the most extensively constructed wetlands in the world, which provide important ecosystem functions of crop production, carbon sequestration, and nutrient cycling (Wittwer et al, 2021). In recent years, incorporating climate change factors into single ecosystem functioning studies has attracted substantial interest, but only limited studies have concentrated on multifunctionality research (Dacal et al, 2022).…”

“…Since preindustrial times, rising surface ozone (O 3 ) and carbon dioxide (CO 2 ) concentrations were considered as the characteristics of atmospheric composition change (IPCC, 2021). A substantial body of studies reported that such changes greatly affected plant growth and soil microbial activities, and thus ecosystem functions (Dacal et al, 2022; Jing et al, 2015; Li et al, 2022; Valencia et al, 2018). For example, elevated CO 2 potentially promoted plant productivity by enhancing leaf photosynthesis and increasing soil microbial biomass (Ruiz‐Vera et al, 2013; Wang, Shi, Li, et al, 2021).…”

“…Soil microbial communities have been identified as pivotal drivers of multiple ecosystem functions (Shi et al, 2021; Zhou et al, 2020). Given the close links between soil microbes and climate change, changes in the community composition, diversity, and biomass of soil microbes could substantially mediate the complicated impacts of global change on multiple ecosystem functions (Dacal et al, 2022; Valencia et al, 2018; Zhou et al, 2020). Previous research has considered the indirect impact of environmental change on ecosystem multifunctionality driven by changes in the diversity of soil microbial communities (Delgado‐Baquerizo et al, 2016; Jing et al, 2015; Zhou et al, 2020).…”

The response of soil biotas to climate change has the potential to regulate multiple ecosystem functions. However, it is still challenging to accurately predict how multiple climate change factors will affect multiple ecosystem functions. Here, we assessed the short‐term responses of agroecosystem multifunctionality to a factorial combination of elevated CO2 (+200 ppm) and O3 (+40 ppb) and identified the key soil biotas (i.e., bacteria, fungi, protists, and nematodes) concerning the changes in the multiple ecosystem functions for two rice varieties (Japonica, Nanjing 5055 vs. Wuyujing 3). We provided strong evidence that combined treatment rather than individual treatments of short‐term elevated CO2 and O3 significantly increased the agroecosystem multifunctionality index by 32.3% in the Wuyujing 3 variety, but not in the Nanjing 5055 variety. Soil biotas exhibited an important role in regulating multifunctionality under short‐term elevated CO2 and O3, with soil nematode abundances better explaining the changes in ecosystem multifunctionality than soil biota diversity. Furthermore, the higher trophic groups of nematodes, omnivores‐predators served as the principal predictor of agroecosystem multifunctionality. These results provide unprecedented new evidence that short‐term elevated CO2 and O3 can potentially affect agroecosystem multifunctionality through soil nematode abundances, especially omnivores‐predators. Our study demonstrates that high trophic groups were specifically beneficial for regulating multiple ecosystem functions and highlights the importance of soil nematode communities for the maintenance of agroecosystem functions and health under climate change in the future.

Changes in the frequency and intensity of precipitation altered the hydrological features, thereafter greatly affecting carbon (C) cycling in terrestrial ecosystems. Soil bacteria are pivotal drivers of the global C cycle in terrestrial ecosystems; however, the responses of soil bacterial communities and the C‐cycle they regulated to precipitation changes remain unclear. Here, we conducted a global meta‐analysis using 98 paired observations from 58 studies to explore the responses of soil bacteria (abundance and diversity) and their C‐related functions (soil respiration) to increased/decreased precipitation. We found that the response of soil bacterial abundance was linearly correlated with precipitation changes, while the response of soil respiration was negatively asymmetric (concave‐down). The relationship among soil bacterial abundance, alpha diversity, and soil respiration was weakened by decreased precipitation, indicating that decreased precipitation exhibited a stronger effect on soil bacterial community and soil respiration. Our study extends the understanding of soil bacteria and their functions in response to precipitation change and facilitates the prediction of soil carbon cycle‐related functions by using soil microorganisms in terrestrial ecosystem models under future precipitation scenarios.
