Figure 7

A. Hernandez and Sukhdeo 2008 [[19]] measured the proportion (%) of isopod intermediate hosts in the diets of four different hosts as determined from stomach content analysis. B. Prevalence of infection (%) with the acanthocephalan parasite Acanthocephalus tahlequahensis whose larval stage is found in the isopod Ceacidotea communis. Bluegill sunfish are recent invaders in this system and are relatively resistant to the parasite; this is a good example of the dilution effect where adding non-competent hosts to the system compromises the transmission rate of the parasite to its normal host.
