| linking larvae and adults of apharyngostrigea cornu, hysteromorpha triloba and alaria mustelae (diplostomoidea: digenea) using molecular data. | abstract because the taxonomy of trematodes is based on adults, the larval stages of most digeneans cannot be identified to species based on morphology alone. molecular data provide a means of linking larval stages to known adults. we obtained sequences from the barcode region of cytochrome oxidase i (co1) from adult and larval parasites of fish, frogs, birds, and mammals across north america. sequences from adult apharyngostrigea cornu, hysteromorpha triloba, and alaria mustelae (diplostomoidea ... | 2011 | 21510747 |
