Predation on spawn and adults of Chaunus dorbignyi (Dumeril & Bibron, 1841) (Amphibia, Anura) by leeches (Hirudinea) in southern Brazil.

Two species of leeches (Hirudinea) are reported as frequently associated with amphibians in Rio Grande do Sul state, southern Brazil. We observed the predation of eggs of the bufonid Chaunus dorbignyi; remarkably, the remaining eggs of this clutch did not complete their embryologic development, probably due to a negative effect caused by the leeches. We report on additional observations of leeches feeding on other anuran species.

Helminth parasites of Leptodactylus podicipinus (Anura: Leptodactylidae) from south-eastern Pantanal, State of Mato Grosso do Sul, Brazil

Forty-three specimens of Leptodactylus podicipinus (Anura: Leptodactylidae) were collected in the south-eastern Pantanal, municipality of Corumba, State of Mato Grosso do Sul, Brazil in February and July 2007, and examined for endoparasites. Forty (93%) specimens were infected with at least one helminth species. The predominant parasites were nematodes (Aplectana sp., Cosmocerca podicipinus, Oswaldocruzia lopesi, Physalopteroides venancioi, Rhabdias sp.), but the trematode Catadiscus propinquus also showed high prevalence. The trematodes Infidum infidum and Travtrema stenocotyle were also found, but in only one specimen. Adult frogs showed higher parasite diversity than subadults. Leptodactylus podicipinus was preferentially infected by direct life-cycle parasites and was reported as a new host record for seven helminth species.
