Fig. 2From: Colony level fitness analysis identifies a trade-off between population growth rate and dauer yield in Caenorhabditis elegansThe colony fitness assay. a Measurement of dauer yield (colony fertility). b Assessment of variation in food patch size; the degree of variation is modest. Mean ± S.D. (n = 10). c Illustration of colony appearance at boom and bust. The latter is distinguished by absence of the E. coli lawn, and the dispersal of worms across the entire agar plate [33]Back to article page
