| comparative cytogenetics of physalaemus albifrons and physalaemus cuvieri species groups (anura, leptodactylidae). | recently, physalaemus albifrons (spix, 1824) was relocated from the physalaemus cuvieri group to the same group as physalaemus biligonigerus (cope, 1861), physalaemus marmoratus (reinhardt & lütken, 1862) and physalaemus santafecinus barrio, 1965. to contribute to the analysis of this proposition, we studied the karyotypes of physalaemus albifrons, physalaemus santafecinus and three species of the physalaemus cuvieri group. the karyotype of physalaemus santafecinus was found to be very similar t ... | 2014 | 25147623 |
| larval digenetic trematodes in tadpoles of six amphibian species from northeastern argentina. | this article presents a survey of metacercariae found in tadpoles of 6 amphibian species collected near the city of corrientes, corrientes province, argentina. larval digenetic trematodes of the following species were found: (1) travtrema aff. stenocotyle cohn, 1902 (plagiorchiidae) from physalaemus santafecinus, physalaemus albonotatus, odontophrynus americanus, elachistocleis bicolor, scinax nasicus, and leptodactylus latinasus; (2) styphlodora sp. (plagiorchiidae) from o. americanus and e. bi ... | 2009 | 19045934 |
| toxicity of the fungicide trifloxystrobin on tadpoles and its effect on fish-tadpole interaction. | contamination of aquatic systems is a major environmental stress that can interfere with predator-prey interactions, altering prey or predator behavior differentially. we determined toxicity parameters of the fungicide trifloxystrobin (tfs) and examined its effects on predation rate, using a fish predator (synbranchus marmoratus) and four anuran tadpole species as prey (rhinella arenarum, physalaemus santafecinus, leptodactylus latrans, and elachistocleis bicolor). tfs was not equally toxic to t ... | 2012 | 22386454 |
