The complete mitochondrial genome ofLithobates catesbeianus(Anura: Ranidae)

Mitochondrial DNA, 2013
The complete mitochondrial genome of Lithobates catesbeianus (Anura: Ranidae) is sequenced to analyze the gene arrangement. It is a circular molecule of 18,241 bp in length including 37 genes typically found in other frogs. The AT content of the overall base composition of L. catesbeianus is 59.9%.

Alteration of intestinal microbiota-intestinal barrier interaction interferes with intestinal health after microcystin-LR exposure in Lithobates catesbeianus tadpoles.

Aquatic Toxicology
There remains uncertainty regarding the influence of microcystin-leucine arginine (MC-LR) on amphibian intestinal health, specifically how MC-LR interferes with intestinal microbiota following exposure to environmental concentrations.

Influence of temperature on biomarker responses of bullfrog tadpoles (Lithobates catesbeianus) exposed to the herbicide ametryn.

Chemosphere, 2022
The S-triazine herbicide ametryn (AMT) is relatively low adsorbed in soils and has high solubility in water, thus believed to affect non-target aquatic organisms such as amphibians.

INFLUENCE OF TEMPERATURE ON GROWTH, DEVELOPMENT AND THYROID METABOLISM OF AMERICAN BULLFROG TADPOLES (LITHOBATES CATESBEIANUS) EXPOSED TO THE HERBICIDE TEBUTHIURON.

Environmental Toxicology and Pharmacology, 2022
The influence of temperature (25 and 32° C) on the negative effects of the herbicide tebuthiuron (TBU, 0, 10, 50 and 200ng.L-1, 16 days) on thyroid function and metamorphosis of Lithobates catesbeianus tadpoles was evaluated.

Hepatic and blood alterations in Lithobates catesbeianus tadpoles exposed to sulfamethoxazole and oxytetracycline.

Chemosphere, 2022
In this study the effects of environmentally realistic concentrations of the antibiotics sulfamethoxazole (SMX) and oxytetracyclyne (OTC) on Lithobates catesbeianus tadpoles were evaluated, through the analyzes of the frequencies of micronucleus and ...

Diet of the American Bullfrog Lithobates catesbeianus Naturalized on Okinawajima, Ryukyu Archipelago, Japan

Current Herpetology, 2021
: The diet of the nonnative American Bullfrog Lithobates catesbeianus occurring in Ogimi Village of Okinawajima, Ryukyu Archipelago, is investigated. Seventy two of 89 frogs (nine adults, five subadults, and 58 juveniles) captured had food items in its ...

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,
