  • For an explanation of values and symbols, see the footnote to Table 1. The diameter of the food patch was 0.2 cm for P. pacificus; 1.0 cm for C. remanei, C. japonica, and C. sp. (DF5070); and 2.0 cm for C. briggsae. Pairwise contrasts were hermaphrodite versus male, virgin female versus male, and mated female versus virgin female.
