Acute and chronic effects of Cr(VI) on Hypsiboas pulchellus embryos and tadpoles [PDF]
Diseases of Aquatic Organisms, 2006 In the last few years there has been great concern about declines in the abundance of several species of amphibians around the world. Among amphibians, anurans have a biphasic life cycle, with aquatic tadpoles and generally terrestrial adults, and they have an extremely permeable skin, making them excellent indicators of the health of the environment ...

Herpetologica, 2010 Abstract We describe a new species of the Hypsiboas pulchellus Group from the eastern Andes of central Peru (Region Pasco). Calls of both H. melanopleura and the new species are described. The new species is more similar to H. melanopleura and H. palaestes but differs in morphological characters and in coloration pattern.

We redescribe Hypsiboas semiguttatus (Lutz, 1925) and describe its tadpole and vocalization. We also describe a new species, previously confused with H. semiguttatus from Misiones, Argentina, and potentially from Brazil. This new species differs from H.

South American Journal of Herpetology, 2011 6 Corresponding author. ABSTRACT. Intrapopulation variation includes age and sexual variation, but also individual niche specialization. Individual specialization has important effects on dynamics at population or community levels. Environmental variation and intraspecific interactions are factors that can promote or enhance this kind of variation ...

Abstract The intensification of modern agriculture may impact amphibian populations through habitat loss and the direct and indirect effects of the pesticides upon which it relies. The increased homogeneity of modern agricultural landscapes may be detrimental in times of extreme low and high temperatures associated with climate change, as refuge ...

Dermocystid-Chytrid Coinfection in the Neotropical Frog Hypsiboas pulchellus (Anura: Hylidae)
Journal of Wildlife Diseases, 2014We present gross and histologic evidence of coinfection in amphibians by fungal-like parasites of the order Dermocystidia (Amphibiocystidium sp.) and the fungus Batrachochytrium dendrobatidis. The condition was observed in frogs Hypsiboas pulchellus (Hylidae) from Uruguay in 2009 to 2012.

We report infection by Ichthyophonus sp. in a South American amphibian, the hylid frog Hypsiboas pulchellus in Uruguay. This frog had a large subcutaneous mass over the urostyle and dorsal musculature comprised of parasitic cysts with mild granulomatous inflammation but otherwise appeared healthy.
