This is an essential area of study as shifts in microbial associations may influence community stability and function, driving differences in disease tolerance. Here, we analyzed the networks of the soil and salamander skin core bacterial communities along a 65-km urbanization gradient originating in New York City. We leveraged network analysis tools that help account for the biases inherent in 16S rRNA amplicon datasets, finding that soil networks were the most complex and stable, but complexity and stability increased with urbanization intensity in salamander networks. The network of Bd-positive salamanders was also more complex and stable than that of Bd-negative salamanders.

This limitation is largely owing to difficulties in their cultivation, and we hypothesize that the difficulty exists because substrate and mineral concentrations in the cultivation medium are not tuned to a specific environmental condition under which these organisms live. To address this hypothesis, this study proposes a novel custom-made medium approach for chemolithotrophic Fe(II)-oxidizing bacteria; a method that manipulates medium components through diligent analysis of field environment. A new custom-made medium simulating energy substrates and nutrients under the field condition was prepared by modifying both chemical composition and physical setup in the glass-tube medium. In particular, the modification of the physical setup in the tube had a significant effect on adjusting dissolved Fe(II) and O2 concentrations to the field environment. Using the medium, Gallionellaceae members were successfully enriched and a new Gallionellaceae species was isolated from a natural hot spring site.
