A day in the life of the Penn Station microbiome

To gauge the persistence of a microbial signature at a station, we sampled one train station (Penn Station) in triplicate every hour on the hour during a weekday. We found that certain taxa are prevalent at every time point, yet a high degree of fluctuation was observed in some genera over the course of the day. For instance, Pseudomadaceae has its greatest abundance between 11:00 and 13:00, and Moraxellaceae was greatest at the end of the day. However, for the majority of families, the peaks greatly vary by the time of day, with low traces at the rest of the time intervals.
