Feature importance of explanatory variables for each bacterial OTU. X-axes are the explanatory variables. The explanatory variables are categorized and color coded: red – chemical, grey – physical, blue – biological. Biotic (environmental) ocean measures consisted of ammonium (NH4, µM), silicic acid (Si, µM), nitrate (N, µM), phosphate (P, µM), temperature (WTMP, °C), and Domoic Acid (DA, mg/L). Biotic measures include Alexandrium spp. (Alx. Spp. cells/L), Pseudo-nitzschia in the size range of the functional group seriata, (Ps-nt. Seri. cells/L), and chlorophyll-a (Chl-a. mg/m3) as a proxy.
