helminth community structure in tadpoles of northern leopard frogs (rana pipiens) and woodhouse's toads (bufo woodhousii) from nebraska.	currently, little information is available on helminth community structure in tadpoles, the ephemeral, feeding, non-reproductive larva stages of anurans. we examined the helminth community structure in tadpoles of northern leopard frogs, rana pipiens, and woodhouse's toads, bufo woodhousii, from a first-order stream in western nebraska. specifically, we were interested in how species-specific difference in size, time to metamorphosis, and habitat partitioning among larval anurans affect their he ...	2015	26346456
redescription of the frog bladder fluke gorgoderina attenuata from the northern leopard frog, rana pipiens.	morphological characters used to differentiate north american bladder flukes, gorgoderina spp., are problematic and different authors use different morphological characteristics for distinguishing species. more importantly, no type specimens exist for 4 of the 12 north american species infecting anuran and caudatan hosts. a redescription of gorgoderina attenuata (stafford, 1902) stafford, 1905 is based on new collections from 6 species of anurans from arkansas, nebraska, new york, and wisconsin. ...	2009	19642808
alternative life cycle strategies and colonization of young anurans by gorgoderina attenuata in nebraska.	studies on life cycles and epizootiology of north american frog bladder flukes indicate that adult frogs become infected predominantly by ingesting tadpoles or other frogs that serve as second intermediate hosts for gorgoderid metacercariae. other studies have indicated that newly metamorphosed frogs are rarely infected with these parasites because they are gape-limited predators that cannot feed on large intermediate hosts such as tadpoles and other frogs. we examined the role of potential inte ...	2009	19071953

helminths of two native frog species (rana chiricahuensis, rana yavapaiensis) and one introduced frog species (rana catesbeiana) (ranidae) from arizona.	the gastrointestinal tracts, lungs, urinary bladders, and body cavities of rana catesbeiana (n = 25), rana chiricahuensis (n = 25), and rana yavapaiensis (n = 37) from arizona were examined for helminths. helminths representing 9 species of trematodes: cephalogonimus brevicirrus, glypthelmins quieta, gorgoderina attenuata, haematoloechus complexus, haematoloechus langiplexus, megalodiscus temperatus, alaria sp., clinostomum sp., and an unidentified strigeid; and 4 species of nematodes: falcaustr ...	1998	9488361
