| small frogs get their worms first: the role of nonodonate arthropods in the recruitment of haematoloechus coloradensis and haematoloechus complexus in newly metamorphosed northern leopard frogs, rana pipiens, and woodhouse's toads, bufo woodhousii. | studies on the life cycles and epizootiology of north american frog lung flukes indicate that most species utilize odonates as second intermediate hosts; adult frogs become infected by ingesting odonate intermediate hosts. newly metamorphosed frogs are rarely infected with these parasites, predominantly because they are gape-limited predators that cannot feed on large intermediate hosts such as dragonflies. we examined the role of the frog diet and potential intermediate hosts in the recruitment ... | 2007 | 17539412 |
| distribution and reproductive strategies of gyrinicola batrachiensis (oxyuroidea: pharyngodonidae) in larvae of eight species of amphibians from nebraska. | abstract a total of 462 tadpoles and salamander larvae of 8 species was examined for the presence of gyrinicola batrachiensis from 5 locations in nebraska. infection by g. batrachiensis occurred in tadpoles of rana blairi, r. catesbeiana, r. pipiens, and bufo woodhousii. tadpoles of hyla chrysoscelis, spea bombifrons, and pseudacris maculata and larvae of ambystoma mavortium were not infected with g. batrachiensis. population structure, defined as prevalence, mean abundance, and mean intensity o ... | 2011 | 21506837 |
| 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 |
| helminth and leech community structure in tadpoles and caudatan larvae of two amphibian species from western nebraska. | currently no comparative studies exist on helminth and leech community structure among sympatric anuran tadpoles and salamander larvae. during june-august 2007-2009, we examined 50 bullfrog tadpoles, rana catesbeiana , 50 barred tiger salamander larvae, ambystoma mavortium , and 3 species of snails from nevens pond, keith county, nebraska for helminth and leech infections. the helminth and leech compound community of this larval amphibian assemblage consisted of at least 7 species, 4 in bullfrog ... | 2012 | 22059380 |
| a new species of myxidium (myxosporea: myxidiidae), from the western chorus frog, pseudacris triseriata triseriata, and blanchard's cricket frog, acris crepitans blanchardi (hylidae), from eastern nebraska: morphology, phylogeny, and critical comments on amphibian myxidium taxonomy. | during march 2001-april 2004, 164 adult anurans of 6 species (47 rana blairi, 35 rana catesbeiana, 31 hyla chrysoscelis, 31 pseudacris triseriata triseriata, 11 bufo woodhousii, and 9 acris crepitans blanchardi) from pawnee lake, lancaster county, nebraska, were surveyed for myxozoan parasites. of these, 20 of 31 (65%) p. triseriata triseriata and 1 of 9 (11%) a. crepitans blanchardi were infected with a new species of myxidium. myxidium melleni n. sp. (myxosporea) is described from the gallblad ... | 2006 | 16884007 |
| 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 |
