Fitness measures of Eu and St hermaphrodites of P. pacificus RS5205 after feeding on prey. (a) Fecundity (brood size) of hermaphrodites after a prey diet and when also fed bacteria (OP50) or fed bacteria and mated (OP50 + males). Whiskers represent the standard error. *p < 0.05, Kruskal–Wallis. (b) Longevity of starved and prey-fed hermaphrodites. Individuals were introduced as J4 (pre-adult) larvae to starvation or prey plates on day 0. On day 8, the last surviving hermaphrodites were removed from assay to test their fertility, for which two out of three were positive. (c) Survival of arrested J2 (first post-eclosion stage) offspring produced by starved or prey-fed hermaphrodites.
