Figure 4.

Decline in C. briggsae isolate-specific pharyngeal pumping rates with age. Each data point represents the mean of 3 replicate counts for each of group of animals. Pumping rates were measured for the same animals two days after the L4 stage and every two days until death. Isolates are color coded as in Figure 3 where zero deletion isolates = triangles, low deletion isolates = squares, and high deletion isolates = circles.
