“…The increase in frequency of Renibacterium and Acinetobacter in SAL streams provides further evidence that these potential salmonoid pathogens (e.g., bacterial kidney disease) are influencing the insect microbial community structure. The only OTU that was detected in higher frequency in NoSAL streams was Bradyrhizobiaceae, a taxonomic group that is commonly associated with plants, soil, aquatic sediments and biofilms, and animal hosts; members within the family are key in nitrogen fixation (Marcondes de Souza et al ., ; Vila‐Costa et al ., ).…”

Carrion decomposition is driven by complex relationships that affect necrobiome community (i.e. all organisms and their genes associated with a dead animal) interactions, such as insect species arrival time to carrion and microbial succession. Little is understood about how microbial communities interact with invertebrates at the aquatic-terrestrial habitat interface. The first objective of the study was to characterize internal microbial communities using high-throughput sequencing of 16S rRNA gene amplicons for aquatic insects (three mayfly species) in streams with salmon carcasses compared with those in streams without salmon carcasses. The second objective was to assess the epinecrotic microbial communities of decomposing salmon carcasses (Oncorhynchus keta) compared with those of terrestrial necrophagous insects (Calliphora terraenovae larvae and adults) associated with the carcasses. There was a significant difference in the internal microbiomes of mayflies collected in salmon carcass-bearing streams and in non-carcass streams, while the developmental stage of blow flies was the governing factor in structuring necrophagous insect internal microbiota. Furthermore, the necrophagous internal microbiome was influenced by the resource on which the larvae developed, and changes in the adult microbiome varied temporally. Overall, these carrion subsidy-driven networks respond to resource pulses with bottom-up effects on consumer microbial structure, as revealed by shifting communities over space and time.

“…In the case of Bradyrhizobiaceae and Pseudonocardiaceae, both families were present in less abundance in PF than in PF. Bradyrhizobiaceae is known for the N fixation capacities of their representatives as one of the most important ecological properties with potential application in agriculture besides other diazotrophic members into the Alphaproteobacteria class (Marcondes de Souza et al, 2014). In relation to Pseudonocardiaceae, some of their representatives are able to produce bioactive compounds with antimicrobial activity, and to thrive under strongly UV-B irradiation (Bull et al, 2018).…”

Composition, Predicted Functions and Co-occurrence Networks of Rhizobacterial Communities Impacting Flowering Desert Events in the Atacama Desert, Chile

et al. 2020

Astorga-Eló et al. Rhizobacteria Affecting Atacama's Flowering Desert occur in C. longiscapa during FD, highlighting to Kouleothrixaceae family as keystone taxa. Taken together this study shows that the composition and function of rhizobacteria vary among and during FD events, where some bacterial groups and their activity may influence the growth and flowering of native plants, and therefore, the ecology and trophic webs in Atacama Desert.

“…In our study, the highest relative abundance of the genes related to the production of adhesive polysaccharides were harbored by Bradyrhizobiaceae and Sphingomonadaceae. Both families are common in soils, and often live in a close association with plant roots (de Souza et al, 2014;Glaeser and Kämpfer, 2014). They are also well-known producers of adhesive polysaccharides (de Souza et al, 2014;Glaeser and Kämpfer, 2014).…”

Site-Specific Conditions Change the Response of Bacterial Producers of Soil Structure-Stabilizing Agents Such as Exopolysaccharides and Lipopolysaccharides to Tillage Intensity

et al. 2020

Bacterial Response to Tillage Intensity to tillage intensity had higher potential for exopolysaccharide and lipopolysaccharide production specifically under reduced tillage. This could be especially crucial for aggregate stability, as polysaccharides produced by different taxa have different "gluing" efficiency. Overall, our data indicate that tillage intensity could affect aggregate stability by both influencing the absolute abundance of genes involved in the production of exopolysaccharides and lipopolysaccharides, as well as by inducing shifts in the community of potential polysaccharide producers. The effects of tillage intensity depend mostly on site-specific conditions.
