Table 2 Cell abundances of heterotrophic bacteria and nanoeukaryotes.

From: Iron and manganese co-limit the growth of two phytoplankton groups dominant at two locations of the Drake Passage

	Heterotrophic bacteria	Nanoeukaryotes
	cells 10⁵mL⁻¹	cells mL⁻¹
West
Initial	3.0	37.2
Control	4.0 ± 0.7^a	8.3 ± 7.6^a
+Mn	3.9 ± 0.1^a	25.5 ± 31.5^a
+Fe	4.3 ± 0.8^a	93.0 ± 70.3^a
+FeMn	4.1 ± 0.2^a	74.4 ± 56.6^a
East
Initial	3.0	87.2
Control	3.9 ± 0.2^a	243.6 ± 102.2^a
+Mn	2.9 ± 0.7^a	193.7 ± 45.2^a
+Fe	3.8 ± 0.8^a	345.1 ± 51.1^a
+FeMn	4.5 ± 0.4^a	370.0 ± 76.4^a

Both were determined via flow cytometry at the beginning and the end of the experiment from the communities sampled West and East after exposure to different Fe and Mn availabilities. Values represent the mean ± SD (n = 6). Different letters indicate significant differences between treatments (p < 0.05).
