From: Urban wastewater bacterial communities assemble into seasonal steady states
Top: map of select wastewater treatment plants sampled previously [27]. Bottom: principal coordinate analysis of influent bacterial communities. Yellow points indicate samples from the 5-year Milwaukee WWTP time series, blue points the 11 coldest US cities in the dataset, and red points the 11 warmest US cities in the dataset. Point shapes indicate the sampling period during which wastewater was collected. Points with labels are samples from either southern US cities in January or northern US cities in August
