  abstract = {{A}daptation to local resource availability depends on responses in growth rate and nutrient acquisition. {T}he growth rate hypothesis ({GRH}) suggests that growing fast should impair competitive abilities for phosphorus and nitrogen due to high demand for biosynthesis. {H}owever, in microorganisms, size influences both growth and uptake rates, which may mask trade-offs and instead generate a positive relationship between these traits (size hypothesis, {SH}). {H}ere, we evolved a gradient of maximum growth rate (mu(max)) from a single bacterium ancestor to test the relationship among mu(max), competitive ability for nutrients and cell size, while controlling for evolutionary history. {W}e found a strong positive correlation between mu(max) and competitive ability for phosphorus, associated with a trade-off between mu(max) and cell size: strains selected for high mu(max) were smaller and better competitors for phosphorus. {O}ur results strongly support the {SH}, while the trade-offs expected under {GRH} were not apparent. {B}eyond plasticity, unicellular populations can respond rapidly to selection pressure through joint evolution of their size and maximum growth rate. {O}ur study stresses that physiological links between these traits tightly shape the evolution of competitive strategies.},
