Summary: This study examines the impact of host ecology and evolutionary history on the microbial communities of Amazonian ants. The research shows that habitat does not play a role in structuring ant microbial communities, but ant diet and nesting mode do influence bacterial communities. Additionally, nesting mode is the determining factor for microbial eukaryote communities, while microbial diversity is not correlated with host phylogeny.

Summary: The study aimed to increase the sensitivity of bacterial community analysis without impacting community composition or interfering with cluster formation during sequencing. The modified PCR protocol showed increased sensitivity in detecting bacterial communities in airway samples, crucial for studying the highly variable human airway microbiome.

Summary: Planktonic microbial communities in wetland ecosystems play a vital role, yet they are relatively underexplored compared to other aquatic ecosystems. This study conducted a high-resolution analysis of bacterial and eukaryotic microbial communities in the Florida Everglades, revealing significant variations along the salinity gradient.

Summary: The availability of soil phosphorus can affect plant growth, root-soil interactions, and rhizosphere microbial community composition. This study investigated the rhizosphere microbial communities of 24 species of eucalypts under low or sufficient soil phosphorus availability. It was found that eucalypt species identity was the main factor determining the composition of the rhizosphere microbial community, while the effect of phosphorus availability varied among species.

Summary: Microbial communities in different crop fields respond differently to the application of the herbicide atrazine, as revealed by 16S rRNA gene amplicon sequencing. The nutrient-poor soil showed a different response compared to the nutrient-rich soils, both in terms of atrazine persistence and its effect on bacterial community structure and composition. Specific bacterial degraders of atrazine were more abundant in the contaminated nutrient-poor soil, while bacteria involved in nitrogen cycling were more abundant in the contaminated nutrient-rich soil. Understanding these responses can help in designing precision application strategies.

Summary: This study found that fungal richness, taxonomy, and pathogenic types were significantly higher in hazy days compared to non-hazy days; the influence of air mass trajectories and environmental factors on airborne fungi was significant; strong winds, dry air, and high temperatures were favorable for fungal survival.

Summary: This study provides high-resolution digital pictures and molecular data of male and female I. rugicollis for the first time, and morphological comparison with I. cornutus could not resolve uncertainties in the latter species' validity. Further molecular comparisons with new specimens of I. cornutus are needed to confirm its status. This study represents the first comprehensive molecular phylogenetic analysis of western Palearctic Pholeoixodes species, including I. rugicollis, and confirms the phylogenetic position of the subgenus Eschatocephalus within Pholeoixodes.

Summary: This study reanalyzed data from a large sample storage study, confirming that 95% ethanol is an effective, practical, and cost-effective preservative that can preserve samples at room temperature for weeks. It also identified the optimal ratio of 95% ethanol to sample in stool and saliva samples, providing a solution that enables crowdsourcing microbiome studies and lowers the barrier for collecting diverse samples.

Summary: In this study, a comprehensive method called Qscore was proposed to evaluate the performance of 16S rRNA amplicons in microbial profiling. The method integrated factors such as amplification rate, taxonomic annotation, sequence type, and length. Evaluation of a wide range of microbe species and microbiomes showed that the Qscore-suggested parameters resulted in high precision in microbiome profiling. This study has significant implications for guiding future microbiome studies and enabling the reuse of massive sequence data.

Summary: This study examined the effect of pectin prebiotics on the gut microbiota of chickens. The results showed that the prebiotic supplementation increased the abundance of Enterococcus and improved feed use efficiency and growth performance. The response of the microbiota to antibiotics showed more sex-related differential OTUs compared to the pectin prebiotic. Therefore, sex should be taken into account in interventional studies of gut microbiota.

Summary: 16S rRNA gene amplicon sequencing accurately characterizes microbial taxonomic abundances but lacks functional information. MicFunPred, a new tool, uses core genes to predict metagenomes, showing low False Positive Rate and performing faster with lower computational requirements compared to other tools.

Summary: This study examines the relationship between microbial community dynamics and DMS concentrations in an oceanographic time series conducted on the east Australian coast. The results show that seasonal shifts in microbial community composition affect the net DMSP concentrations, with certain phytoplankton species producing more DMSP than others. Additionally, planktonic bacteria play a significant role in producing DMSP and DMSO in ocean surface waters.

Summary: Pigeon pea, a primary protein source for over a billion people in developing countries, forms symbiosis with N-2-fixing bacteria, particularly Rhizobium spp. The bacterial community associated with pigeon pea is significantly influenced by plant roots location, developmental stage, and soil type, with Proteobacteria being the dominant group. Native symbiont Bradyrhizobium spp. struggles to effectively colonize pigeon pea roots, leading to poor nodulation in Indian soils. This emphasizes the importance of symbiont competitiveness in agricultural soils for improving pigeon pea yield and reducing food poverty.
