Indeed, increased mortality would be maladaptive for the tapeworms, because only live copepods are ingested by the subsequent host.
Half of the copepods received a mixed exposure, using mixtures of the same three tapeworm sibships to infect 12 copepods on each 24-well plate.
The bottom graph summarizes the relationship between the lengths and widths of individual proglottids (237 proglottids from 21 tapeworms).
Despite much interest in molecular phylogeny, molecular studies dealing with families and genera of tapeworms are scarce.
Since some tapeworms had fewer proglottids than others, there are fewer data points for the higher proglottid numbers.
Previous studies indicate that the interaction between the tapeworm and its copepod intermediate host is characterized by a high degree of specificity.
The rats were infected on different days and using different batches of cysticercoids, and the mean number of tapeworms recovered was 26.
Copepods were starved the day before experimental infection with tapeworms.
