Occurrence of Ochoterenella digiticauda (Nematoda: Onchocercidae) infecting the gladiator frog Hypsiboas lundii (Anura: Hylidae) in Brazil

Hypsiboas lundii is a gladiator frog endemic to the Cerrado of central and southeastern Brazil. This species in reproductive period inhabits streams in primary and secondary forests. Despite its wide distribution, the helminth fauna of this species has not been studied yet. Fourteen individuals were sampled and examined for helminth parasites. Three males were infected with Ochoterenella digiticauda (Onchocercidade). The mean abundance and mean intensity of infection were 0.7 ± 0.5 and 3.3 ± 1.9, respectively. All parasites were found in the body cavity of H. lundii, which represents a new host record for O. digiticauda.

Adaptations to salinity and osmoregulation in the frog Thoropa-miliaris (Amphibia, Leptodactylidae)

The leptodactylid frog Thoropa miliaris, from SE Brazil, may live on rocky marine shore, where it thrives on terrestrial and marine invertebrates, and often moves into the intertidal zone. The osmotic concentration of plasma, muscle homogenate and urine of the frogs freshly captured on the rocky shore was higher than those collected far from the sea, or kept in captivity for 6-8 months on a diet free of marine items. Increase in body urea and sodium concentrations, reported in amphibians as a response to hyperosmotic environment, was not found in T. miliaris. Osmotic concentration of the frogs from rocky shore was variable though, ranging from 400 to 980 mOsm/l. Such variation in the osmotic concentration may reflect a territorial behavior for foraging sites, which would result in higher intake of marine items by individuals living closer to intertidal zone.
