Bullfrog (Lithobates catesbeianus) invasion in Uruguay

Biological Invasions, 2007
This is the first report of North American bullfrogs, Lithobates catesbeianus (=Rana catesbeiana), invasion in Uruguay. This Anura was introduced for farming proposes in 1987, but at present most of the farms are closed. At one of these closed farms, located at Rincon de Pando, Canelones, we report the occurrence of a feral population of L ...

Glycosaminoglycans and glycoconjugates in the adult anuran integument (Lithobates catesbeianus)

Micron, 2010
Glycosaminoglycans (GAGs) from the integument of Lithobates catesbeianus were biochemically characterized and histochemically localized. Moreover, carbohydrate distribution was investigated using conventional and lectin histochemistry at light microscopy. Hyaluronan (HA), dermatan sulfate (DS) and a heparanoid were found in the integument. Sulfated and

American bullfrog Lithobates catesbeianus (Shaw, 1802) invasion in Argentina

Biological Invasions, 2009
The American bullfrog (Lithobates catesbeianus) has been introduced throughout the world over the past two centuries. This taxa is a potentially devastating invader because of its large size, prolific reproductive output, and broad ecological niche. Consequently, the extent of this ongoing biological invasion is an increasing conservation concern.

Toxicity of Waterborne Copper in Premetamorphic Tadpoles of Lithobates catesbeianus (Shaw, 1802)

Bulletin of Environmental Contamination and Toxicology, 2010
Toxicity parameters of Copper to pre-metamorphic larvae of Lithobates catesbeianus were evaluated in laboratory conditions. The acute toxicity (as LC-50 96 h) was 3.96 mg Cu(2+) L(-1) (95% confidence interval: 3.21-4.89); the bioconcentration of the metal after 96 h exposure followed an exponential increase.
