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.

The genotoxicity and cytotoxicity of tannery effluent in bullfrog (Lithobates catesbeianus)

Chemosphere, 2017
Some of the most polluting activities occur in bovine skin processing. Tannery generates effluents containing high concentrations of heavy metals and organic compounds. The phases composing the leather production process generate a large volume of tannery effluents that are often discarded in aquatic environments without any previous treatment. However,

CARDIOVASCULAR EFFECTS OF ALFAXALONE AND PROPOFOL IN THE BULLFROG,LITHOBATES CATESBEIANUS

Journal of Zoo and Wildlife Medicine, 2018
Alfaxalone is becoming a popular anesthetic for nonmammalian vertebrates, but the physiological effects of its administration remain largely unknown in these taxa. Therefore, the cardiovascular responses to a clinically relevant dose of alfaxalone (10 mg/kg) are reported in the bullfrog ( Lithobates catesbeianus), following intramuscular (IM) and ...

Insights about the toxic effects of tannery effluent on Lithobates catesbeianus tadpoles

Science of The Total Environment, 2018
Tannery industries are considered highly polluting due to the large production of polluted wastewater [untreated tannery effluent (UTE)]. Although previous studies have already shown the consequences from fish, birds and mammals' exposure to this pollutant, little is known about its toxicological effect on representatives of class amphibian.

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.

Potential Distribution of the American Bullfrog (Lithobates Catesbeianus) in Ecuador

South American Journal of Herpetology, 2012
ABSTRACT. The American bullfrog (Lithobates catesbeianus) is a native species from eastern North America that was introduced to Ecuador in 1985. We built two models in Maxent, (1) one model with native records and, (2) one model with native and invasive records, to provide an approximate map of the potential geographical distribution for this species ...

Fasting elicits immune modulation and leukocyte redistribution in bullfrogs (Lithobates catesbeianus)

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology
An integrated range of behavioral, physiological, and biochemical adjustments reduces metabolic expenditure and energy utilization during fasting to maintain homeostasis. In order to cope with these adjustments, several vertebrates can modulate immune function and corticosterone secretion while fasting to save energy.

Experimental Evidence for American Bullfrog (Lithobates catesbeianus) Susceptibility to Chytrid Fungus (Batrachochytrium dendrobatidis)

EcoHealth, 2013
The emerging fungal pathogen, Batrachochytrium dendrobatidis (Bd), has been associated with global amphibian population declines and extinctions. American bullfrogs (Lithobates catesbeianus) are widely reported to be a tolerant host and a carrier of Bd that spreads the pathogen to less tolerant hosts.

Ultrastructure of the bullfrog (Lithobates catesbeianus‐Shaw, 1802) oviduct in different seasons

Microscopy Research and Technique, 2013
ABSTRACTThe bullfrog (Lithobates catesbeianus) is an exotic animal that adapted perfectly to the climatic conditions of Brazil after introduction in the country. These climatic conditions favor the reproduction and fattening of bullfrogs. However, the development of the bullfrog is significantly reduced in colder regions because low temperatures affect
