Fig. 7From: Symbiosis of the millipede parasitic nematodes Rhigonematoidea and Thelastomatoidea with evolutionary different originsA Mean density of Rhigonematoidea sp. 1 adult female, in Riukiaria spp. infected with only Travassosinema claudiae, only Thelastomatidae spp., and both parasites. Error bars indicate confidence intervals with 95% confidence limit. *p < 0.05, Bootstrap 2-sample t-test for comparing mean densities. B Average ± S.D. of body length of host millipede Riukiaria spp., infected with only T. claudiae, only Thelastomatidae spp., or both parasites. **p < 0.005, Statistical differences were analyzed by Tukey’s multiple comparison test followed by Bonferroni correctionBack to article page
