Summary: Bdellovibrio bacteriovorus can attack biofilms of the pathogen Vibrio cholerae, but the prey biofilms are protected from their predators once they reach a critical maturation threshold. This protection mechanism is determined by the relative contributions of matrix secretion and cell-cell packing of the prey biofilm.

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: We characterized the bacterial and fungal communities in forest soils using CLPP and PCR-DGGE analysis. The results showed clear separation between the O and A horizons in terms of CLPP and DGGE profiles, except for the fungal CLPP. No significant links were observed between the O and A horizons, suggesting different factors influencing the microbial communities. However, there were significant couplings between bacterial and fungal profiles within each horizon, indicating common factors shaping the communities. The potential functioning was not strongly associated with the composition of the microbial community.

Summary: This study evaluated the importance of deterministic and stochastic processes in shaping bacterioplankton community assembly and the impacts of phytoplankton and zooplankton on bacterioplankton through direct and indirect effects. The results showed that environmental variation is a key driver of bacterioplankton assembly, and indirect biotic interactions also play a significant role. Additionally, eutrophication led to differentiation in community structure and increased bacterial diversity.

Summary: Bacterial communities in soil play a critical role in carbon and nutrient cycling. This study investigated the assembly and distribution of bacterial communities at different soil depths. The results showed that bacterial diversity and abundance decreased with soil depth due to limited access to carbon and nutrients. The relative abundance of different phyla also varied with soil depth. The study also found that ecological interactions between bacterial taxa increased with depth, leading to reduced functional redundancy. The study provides valuable insights into the assembly processes of bacterial communities in different soil depths.

Summary: Salinization and nitrogen pollution caused by climate change are significant threats to inland lakes. This study conducted field observations and experiments in East Asian lakes to explore the response of key nitrogen cycle processes to climate-induced changes in salinity. The findings showed that increased salinity inhibited denitrification but had insignificant or positive effects on nitrate reduction to ammonium. Inland lakes act as long-term integrators of climatic conditions, and climate-induced salinization and drying can have negative impacts on nitrogen pollution in these lakes.

Summary: Particle-attached (PA) and free-living (FL) bacterial communities in drinking water reservoirs show spatiotemporal variations in diversity and composition. PA communities are enriched in nitrogen-related processes, while FL communities are enriched in photosynthesis and organic compound degradation. Deterministic processes dominate the assembly of both communities, with environmental filtration having a stronger effect on FL communities. Co-occurrence patterns and keystone taxa differ between PA and FL communities. PA communities are more stable in changing environmental conditions. Nutrients and abiotic and biotic factors have positive and negative effects on co-occurrence networks for both lifestyles.

Summary: This study explores the effects of environmental heterogeneity on the diversity, composition, and degree of overlap between free-living (FL) and particle-attached (PA) bacteria in Lake Taihu, China. The results show that bacterial communities near riverine inflow had high alpha-diversity and a high degree of overlap between FL and PA lifestyles. Cyanobacterial blooms reduced alpha-diversity within the PA lifestyle, while the limnetic area had the lowest bacterial alpha-diversity within the FL lifestyle and a medium degree of overlap between FL and PA lifestyles. Redundancy analysis revealed the factors shaping the variation of FL and PA bacterial communities. The study emphasizes the importance of environmental heterogeneity, riverine input, cyanobacterial blooms, and nutrient status in determining the spatial distribution patterns of FL and PA bacterial communities in freshwater lakes.

Summary: In this study, a new telemetry sensor system was developed to continuously monitor the body temperature of rabbits. The sensor was implanted subcutaneously and the temperature changes were recorded by a personal computer. The temperature data obtained from the telemetry system was consistent with the rectal temperature measured by a digital device. The analysis of body temperature changes confirmed the reliability and usefulness of this system, both in normal conditions and when fever was induced by endotoxin.

Summary: This study investigates the modulation of denitrification and DNRA rates by gene abundances and environmental factors in eutrophic lakes. The results indicate that denitrification rates increase with eutrophication, while DNRA rates do not. The nitrification process provides ample nitrate for denitrification, and certain microbial genera are responsible for these processes. Further eutrophication indirectly affects denitrification and DNRA rates through modulation of N-cycling microbe gene abundances.

Summary: The algal succession in Microcystis blooms of varying biomass under continuous aeration was studied. The results showed that the biomass of Cyanophyta was the lowest in the Medium treatment, while the biomass of Chlorophyta was the highest. Both Chlorophyta and Bacillariophyta biomass were the lowest in the High treatment. The presence of diatom Nitzschia palea in the Low treatment suggests that the algal shift in Microcystis blooms under aeration disturbance is dependent on its initial biomass.
