Biovolume (n = 15), growth rate (n = 3), dispersal rate (n = 5), and bootstrap estimates of competitive rank (high rank means high competitive ability) of the four species

Species	Biovolume (103 μm3)	Growth rate (ind ind−1 day−1)	Dispersal rate (ind ind−1 day−1)	Competitive rank (2.5, 97.5 percentiles)
Tachysoma	17	1.75	0.001	2.87 (2, 4)
Stylonychia	31	1.47	0.014	3.66 (2, 4)
Frontonia	89	0.35	0.003	1.29 (1, 3)
Paramecium	216	0.62	0.083	2.18 (1, 4)

Competitive ability was measured by comparing growth in single species treatments with performance in all pairwise species combinations (n = 3). Data are from Limberger and Wickham (2011). Competitive ranks have been recalculated, as fewer species were used in the present experiment. Competitive ranks are therefore based only on competition trials containing pairs of those four species
