Summary: Managing and engineering microbial communities requires the ability to predict their composition. While little work has been done on predicting compositions on evolutionary timescales, this study shows that community composition typically changes during evolution, but the composition of replicate communities remains similar. These changes were also predictable, suggesting that it may be possible to forecast the evolution of microbial communities even on long timescales.

Summary: Acute environmental perturbations cause changes in microbial community composition and selection of different phylotypes, while chronic perturbations maintain community stability and can lead to the establishment of alternative stable states. This study also demonstrates the functional resilience of ecosystem following environmental perturbations.

Summary: This study utilized a top-down manipulation approach to investigate the role of biotic interactions in shaping soil microbial communities, revealing the importance of such interactions and identifying microbial community assembly rules. Modified biotic interactions had a greater impact on activities related to nitrogen cycling than carbon cycling, providing insights into microbial interactions in complex ecosystems and their relationship with ecosystem function.

Summary: The study found that family-level convergence in microbial communities reflects a reproducible metabolic organization, while taxonomic divergence among replicate communities arises from multistability in population dynamics. Multistability can lead to alternative functional states in closed ecosystems but not in metacommunities.

Summary: Biofiltration is a crucial water treatment technology for producing safe drinking water. It is gaining worldwide interest due to its advantages of no chemical addition, low energy input, and high removal efficiency of organic compounds, undesirable taste and odours, and pathogens. This review highlights the microbial ecology of three commonly used biofiltration processes in drinking water treatment plants and summarizes their characteristics, removal performance, and newly revealed mechanisms. It also discusses the role of microbial communities in removing nutrients, organic compounds, and pathogens, and suggests future perspectives for a comprehensive understanding of the microbial ecology of biofiltration.

Summary: The combination of ozonation and biofiltration processes has become practical for advanced water reclamation, but microbial community characterization in biofilters for water reuse applications has not been as well studied as in drinking water biofilters. Understanding the microbial community characteristics is crucial for addressing potential risks and mechanisms affecting public health and the environment. There are significant gaps in relating biodegradation performance and metabolic processes in the biofilter, highlighting the need for future research in this area.

Summary: This study assessed the impact of alternative land-surface disturbances (high-intensity winter-grazing and wildfire) compared to conventional summer-long continuous grazing on the soil microbial community. The results showed that neither wildfire nor high-intensity winter-grazing significantly impacted the soil microbial community. However, the response of the soil microbial community was influenced by the composition of aboveground vegetation.

Summary: Lake Urmia in Iran is a hypersaline environment with a salinity of about 27%. Metagenomic analysis revealed that the microbial community in the lake is dominated by Haloferacaceae family (69.8%), mainly Haloquadratum (59.3%) and Halonotius (9.1%). The bacterial community is mainly composed of Salinibacter ruber (23.3%). Genomic variation analysis showed a high level of SNVs and insertions in Lake Urmia's community, possibly due to transformation caused by the extreme conditions and high ionic concentrations.

Summary: The study found that as artificial lakes mature, their metabolism shifts from heterotrophic to autotrophic, making them CO2 sinks but increasing CH4 emissions. Eutrophication may reverse lakes' contribution to climate carbon budgets, but also raises CH4 emissions, enhancing their climate impact. Mitigation strategies to maintain intermediate maturity levels are needed to limit artificial waterbodies' climate impacts.

Summary: Freshwater ecosystems play a significant role in methane emissions and this study investigated the effects of temperature on microbial community structure and methane production pathways in sub-Antarctic lake sediments. The research found that temperature had a significant impact on methane production rates, particularly when methanogenic precursors such as acetate and H-2/CO2 were introduced.

Summary: This study presents a new approach to unravel bacterial phylogeographic patterns in the oceans, combining community-wide survey by 16S rRNA gene metabarcoding and intra-species resolution through the oligotyping method. The research focused on the bacterial genus Spirochaeta in the Southern Ocean, revealing genetic differentiation and phylogeographic structure among distant biogeographic provinces. The findings suggest the Antarctic Polar Front as a barrier to bacterial dispersal and the Antarctic Circumpolar Current as the main driver of gene flow, with historical processes governing spatial turnover among Spirochaeta populations.

Summary: This study compared two different strategies for acclimating the anaerobic digestion microbiome to increasing ammonium concentration. Results suggest that long-term cumulative exposure to ammonia disrupted the microbiome more strongly than direct (independent) ammonium additions. Different bioindicators with varying NH4+ tolerance capacity were identified among VFA producers and syntrophic VFA oxidizers.

Summary: As global warming increases the availability of permafrost organic carbon, methane-cycling becomes increasingly important in high-latitude ecosystems. This study examined samples from three high-latitude regions and found that physicochemical properties, especially pH, played a significant role in shaping the microbial communities involved in methane production and consumption. Geographic distance also influenced the diversity of these microorganisms, with dispersal limitation playing a role. Indicator species were identified to characterize different ecological niches. This research provides insight into the distribution of methane-cycling microbes in high latitudes under climate change predictions.
