From: Low diversity of planktonic bacteria in the tropical ocean
Bacterial diversity, water temperature and salinity in the epipelagic zone of the Atlantic Ocean.
Bacterial diversity is shown as the ln of OTU richness (S) from 20 to 200 m depth from 51 °S to 47 °N for the three size fractions of the marine plankton: FL (free living bacteria, 3–0.22 μm filtrate) (a), SPA (small particle associated bacteria, 8–3 μm filtrate) (b) and LPA (large particle associated bacteria, >8 μm filtrate) (c). Panel (d) shows the water temperature and (e) the salinity. The five sections were generated with the free software Ocean Data View (Schlitzer, R., Ocean Data View, http://odv.awi.de, 2015), version 4.7.2, in accordance with the metadata reported in Supplementary Table S2.
