Summary: Biotic interactions play a major role in microbial diversity, but they have not been adequately quantified, leading to unexplained residual variation in microbial biogeographic studies. In this study, a holistic approach was proposed to understand the importance of inter-domain interactions in shaping microbial diversity by considering community-level characteristics. The research found that eukaryotic characteristics were better predictors of bacterial diversity indices and community structure compared to environmental and spatial variables alone. The study also highlighted the significance of non-grazing interacting processes in shaping bacterial diversity and community assembly.

Summary: This study investigated the community diversity patterns among protistan assemblages and identified putative vent endemic microbial eukaryotes through 18S rRNA amplicon sequencing. The results showed that deep-sea vents harbor diverse microbial eukaryotic communities composed of various protists. Each vent field supports distinct and highly diverse assemblages, including potentially endemic or novel vent-associated strains.

Summary: DNA extraction and preservation methods have significant impacts on the community composition of both eukaryotes and prokaryotes. The choice of extraction method has a more pronounced bias on eukaryotes than on prokaryotes. Careful consideration of DNA preservation and extraction methodology is crucial for obtaining representative community profiles of eukaryotic microbial communities.

Summary: Microbial electrochemical technologies have the potential for energy recovery and wastewater treatment, but the impact of micro/nanoplastics on these systems is not well understood. This study found that polystyrene nanoplastics had an inhibitory effect on the microbial communities in a microbial electrolysis cell, reducing current density and hydrogen production, and increasing extracellular polymeric substance secretion.

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: This study provides a comprehensive overview of the biodiversity of microorganisms in biocrusts and neighboring sand along the Baltic Sea coast. The results show that biocrusts mainly recruit their microorganisms from the neighboring sand, and although the taxa richness is lower in biocrusts compared to sand, there is a higher number of co-occurrences. This study highlights the importance of comparing biocrusts with neighboring bare surface substrates to better understand biocrust development, and the target sequencing approach helps identify key players and potential biotic interactions.

Summary: Although there are approximately 25 million seamounts in the ocean, little is known about their microbial ecology. This study provides evidence that seamounts are unique habitats, harboring distinct microbial communities, and exhibit a distance-decay pattern. Environmental selection and dispersal limitation shape the observed biogeography. Furthermore, a framework linking community assembly with successional dynamics in seamounts is established, showing the dominance of stochasticity during initial community establishment and the increase in the importance of environmental selection in shaping subsurface communities.

Summary: The environmental fate of plastic particles in water bodies is influenced by microbial biofilm formation, but the mechanistic basis for these effects is unknown. This study established a defined biofilm community and used a freshwater snail for grazing experiments. The results showed that the microbial community composition was influenced by the incubation site rather than the plastic material. A photoautotrophic consortium sustained growth and metabolism of the grazers. This study suggests that domesticated photoautotrophic microbial communities can be a valid approach for establishing laboratory ecotoxicological assays with higher environmental relevance.

Summary: The number of seals in the Baltic Sea has increased dramatically in recent years, causing significant damages to coastal fisheries, especially the coastal cod fishery. An empirical study found that seal interactions play an important role in explaining the declining number of active fishing vessels in the Swedish cod fishery.

Summary: The study found that early desiccation triggers dynamic fluxes of CO2 and CH4, while prolonged desiccation constrains aerobic activity. Rainfall can boost CO2 fluxes, modulated by both rainfall size and preceding desiccation time. Desiccation also reduces WSOC content and leachable labile compounds from sediment.

Summary: Mixotrophic and heterotrophic protists play an important role in aquatic microbial food webs, but their impact on bacterial communities is unclear. Short-term grazing experiments showed that different protist species had varying effects on bacterial community composition. Mixotrophs had a lower grazing rate but promoted higher bacterial diversity, while the phagoheterotroph had the highest grazing rate and selectively structured the bacterial communities. The structuring impact of protist taxa on bacterial communities seemed to depend on their trophic mode.
