Size classes of bacteria^a used in grazing experiments

Size class (range of length [μm])	Avg length (μm)	Aspect ratiob (μm)	Avg volc (μm3)
0.1–0.5	0.5	1.3 ± 0.1	0.06 ± 0.01
0.5–0.8	0.7	1.2 ± 0.04	0.14 ± 0.02
0.8–1.5	1.1	2.0 ± 0.1	0.21 ± 0.02
>1.5	1.8	2.1 ± 0.3	0.87 ± 0.05

^aPrimarily rod-shaped bacteria. 

^bRadius (r) = 0.5(L/aspect ratio), where L is cell length. Values are means ± standard errors. 

^cCell volume = [πr²(L − 2r)] + (4/3π(r³)], where r is radius. Values are means ± standard errors.
