Fig. 4 in Effects of the Naturally Occurring Parasitic NematodeChondronema passaliLeidy on Lifting Strength and Captivity-Related Body Mass Patterns in the Horned Passalus Beetle,Odontotaenius disjunctus(Illiger) (Coleoptera: Passalidae)

Fig. 4. Patterns of weight loss in Odontotaenius disjunctus with or without Chondronema passali across three weeks of study. Beetles lost 11% of their initial body mass when placed in captivity (A), which was not fully regained at the end of three weeks. Parasitized beetles tended to lose less mass than did non-parasitized beetles; this effect was not significant at Week 1 (B), but was significant at Week 3 (C). Whiskers above and below means in A represent standard errors; those in B and C represent 95% confidence intervals.
