Nematode parasites of two anuran species Rhinella schneideri (Bufonidae) and Scinax acuminatus (Hylidae) from Corrientes, Argentina
TLDR
The nematological fauna of most anuran species from Corrientes province, north of Argentina; has not been studied and nematode species found in Rhinella schneideri and Scinax acuminatus are reported for the first time.Abstract:
The nematological fauna of most anuran species from Corrientes province, north of Argentina; has not been studied. We report for the first time the nematode species found in Rhinella schneideri and Scinax acuminatus. Forty four amphibians representing two species (R. schneideri -six males, three females and two juveniles- and S. acuminatus -fifteen males and eighteen females) were collected near the city of Corrientes, between January 2002 and December 2003 and searched for nematodes. R. schneideri contained eight species of nematodes (adults: Rhabdias fuelleborni, R. elegans, Oswaldocruzia proencai, Cosmocerca podicipinus, C. parva and Falcaustra mascula; larvae: Porrocaecum sp. and Physaloptera sp.), and S. acuminatus contained three (adults: Cosmocerca parva and Oxyascaris caudacutus; larvae: Physaloptera sp.). We present morphol- ogy (scanning electron microscope) and metric information, range extensions, and new host records for these nematode species. Rev. Biol. Trop. 56 (4): 2147-2161.

TL;DR: A terrestrial assemblage database of unprecedented geographic and taxonomic coverage is analysed to quantify local biodiversity responses to land use and related changes and shows that in the worst-affected habitats, pressures reduce within-sample species richness by an average of 76.5%, total abundance by 39.5% and rarefaction-based richness by 40.3%.

TL;DR: The biodiversity of helminth parasites in South American amphibians is documented to identify gaps in the authors' knowledge, which in turn may guide subsequent studies.

Infection dynamics of the lungworm rhabdias pseudosphaerocephala in its natural host, the cane toad (bufo marinus), and in novel hosts (native australian frogs)
TL;DR: Investigation of the dynamics of infections of the toad parasite by conducting histologic examinations of cane toads and three native Australian frogs finds an enhanced ability of the lungworm to locate the target organ (the lungs), and an increase in rates of parasite survival within this host.

TL;DR: Two new lung-dwelling nematode species of the genus Rhabdias Stiles et Hassall, 1905 were discovered in Caxiuanã National Forest, Pará state, Brazil.

Integrated evidence reveals a new species of Cosmocerca (Ascaridomorpha: Cosmocercoidea) from the Asiatic toad Bufo gargarizans Cantor (Amphibia: Anura).
TL;DR: Phylogenetic analyses using maximum likelihood (ML) inference based on the partial ITS and cox1 sequence data both supported the new species to be a member of the genus Cosmocerca, and formed a sister relationship to C. japonica.

Species affinity and infracommunity ordination of helminths of leptodactylus chaquensis (anura: leptodactylidae) in two contrasting environments from northeastern argentina
TL;DR: The body size of the host was the important factor in determining parasite richness and the mean richness, mean diversity, and evenness of helminths were significantly different between the habitats (P < 0.05).
