Summary: This study examines the assembly processes of bacterial and microeukaryotic communities along a salinity gradient and reveals that increasing salinity leads to a dominant role of selection over dispersal, resulting in decreased community turnover. The richness of microeukaryotes decreases with increasing salinity, suggesting that the net effect of selection and dispersal is determined by environmental conditions and microbial ecologies.

Summary: Microbial communities exhibit spatial structure at different scales due to constant interactions with the environment and dispersal limitation, but this has received less attention in the context of host-associated microbial communities. The adoption of methods accounting for spatial variation in these communities could help address open questions in microbial ecology and unlock the full potential of microbiome-aided medicine. Methodological advancements in spatial modeling and analysis of microbiota could benefit theoretical and applied ecology, as well as contribute to the development of novel industrial and clinical applications.

Summary: This study analyzes the spatial and temporal pattern of China's energy mismatch and efficiency loss using a labor-capital-energy-environment resource mismatch model based on provincial panel data from 2004 to 2018. The study finds that although the degree of resource misallocation has decreased, the problems of excessive energy allocation and inadequate energy allocation still persist, with regional variations. Environmental regulation can effectively reduce energy mismatch, and the rebound effect of technological progress is the main factor aggravating inadequate energy allocation.

Summary: This study investigated the diversity, assembly processes, spatial distribution pattern and driving factors of prokaryotic and eukaryotic microbial communities in Biological Soil Crusts (BSCs) in four different habitats on the Qinghai-Tibet Plateau. The results showed that habitat-specific environmental factors regulated the composition, diversity and spatial variability of BSC microbial communities. Soil organic carbon and soil water content were found to be the most important factors affecting the spatial differences in prokaryotes and eukaryotes, respectively. Precipitation was the main driver of microbial community spatial patterns in BSCs, rather than temperature.

Summary: It has been found that environmental variability and cyanobacterial blooms have significant impacts on bacterial communities in marine and freshwater ecosystems. However, the long-term response of ciliate communities to such changes, especially in subtropical lake and reservoir ecosystems, remains unclear. In this study, we analyzed 9-year planktonic ciliate data from two subtropical reservoirs to investigate the role of cyanobacterial blooms and environmental variability on ciliate temporal dynamics. Our findings suggest that the interannual variability of ciliate communities was more strongly related to cyanobacterial blooms than to other environmental factors or seasonality. Additionally, we found that short-term blooms increased the selection pressure and drove a significant turnover of ciliate communities.

Summary: This study found that the spatiotemporal variability in water microbial communities is influenced by relic DNA. After removing relic DNA, the composition of microbial communities showed significant changes, especially for microeukaryotes. Moreover, relic DNA removal also altered the relationships between microeukaryotic community composition and environmental factors. Therefore, more studies on the abundance, decay rate, and functioning of nonviable DNA in freshwater ecosystems are recommended in the future.
