Urban park soil microbiomes are a rich reservoir of natural product biosynthetic diversity
NYC parks harbor a large diversity of natural product NRP and PK biosynthetic gene clusters. Important natural products originally isolated from disparate sites spanning the globe are represented in urban soils from a single city.

In the presence of yeasts, some Streptomyces species differentiate from cononical static mycelia into highly motile explorer cells. This is triggered by low glucose conditions and high pH conditions. Explorer cells emit an alkaline VOC that raises media pH, and this signal can trigger physically distant Streptomyces cells to begin exploring.

When amino acids are available, auxotrophs emerge under strong positive selection. Auxotrophs also evolve in the absence of amino acids at lower rates. Negative frequency dependent-selection supports the stable coexistence of auxo- and proto- trophs.

Cell morphology can drive spatial structure and influence the fitness landscape in mixed biofilm cultures.

Virulence adaptive polymorphisms (VAPs) recombine in environmental V. cholerae gene pools, certain VAP combinations are enriched, and subsequent acquisition of virulence genes in these pre-adapted genomic background supports a transition to pathogenic phenotypes.

Microbial seed banks can form in nutrient rich habitats, and these dynamics are influenced by microscale dispersal dynamics and spatial and resource complexity.

Assembled genomes from the Norse god phyla (within the Asgard archaea superphylum) associate phylogenetically with eukaryotes and also encode many eukaryotic cell features, suggesting that the last common ancestor of archaea and eukaryotes possessed greater cellular complexity than previously thought.

Bacillus phage use phage-specific small peptides to communicate to subsequent progeny about lytic or lysogenic decisions; after each infection round, AimP accumulates and eventually triggers lysogeny.

Actinomycetes product a vast array natural products of important consequence from the host to the ecosystem level. In situ ecology of NPs will aid in discovery and production of novel NP for human use.

Compositional analysis of microbial communities are sensitive to 16S rRNA copy number, which differs across taxa and also within a species under differing growth conditions.

Phylogenomic networks reveal limited phylogenetic range of lateral gene transfer by transduction
Gene exchange mediated by phages has important evolutionary consequences, but transduction is limited by genetic similarity as opposed to ecological co-occurrence. A substantial number of transduction event are duplications, or autology.

Microdiversity shapes the fundamental niche space and biogeography of microbial taxa; this diversity is generated through the Renaissance model (gaining new traits usually through HGT) or the Maestro model (improving a single trait usually through mutation).

Metabolite and microbe abundance in biocrusts after a wetting event show a i) negative relationship for consumed metabolites and ii) positive relationship for produced metabolites. Metabolite profiles correspond to microbial community structure.

Soil microbes can be transfered into the atomosphere and dispersed across spatial scales through raindrop mediated aerosolization. The number of bacteria trasnferred through aerosols depends on soil type, surface temperature, bacterial surface density, and raindrop velocity.

Symbiotic legumes (i.e. legumes that rely on nitrogen-fixing soil rhizobia) are less likely to disperse and colonize non-native ranges than non-symbiotic legumes, suggesting that biogeography of rhizobia influence the global distribution of plants.
