Growth Rate Consequences of Coloniality in a Harmful Phytoplankter
(A) Relationship between growth rate (day−1) and initial colony equivalent spherical diameter (ESD, mm) between days 1 and 7 for individual colonies of four M. aeruginosa genotypes (ALB3R708, Erie31F1206, HudsonBD02, and SwanBS02). (B) Comparison of colony growth rates for small colonies of four M. aeruginosa genotypes grown in chambered slides in isolation (dark bars) or in association with a large colony of the same genotype (white bars). Error bars = 1 standard error. Inset numbers are sample sizes.
