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 ...

The North American tapeworm Ophiotaenia saphena (Cestoda: Proteocephalidae) in frogs (Ranidae) of Europe: introduction via the American bullfrog (Lithobates catesbeianus)?

Systematics and Biodiversity
Frogs (Amphibia: Ranidae) in Europe have been intensively studied for parasites for decades, but no proteocephalid tapeworms (Cestoda) have been found.

Evaluation of nutritional composition and technological functionality of whole American Bullfrog (Lithobates catesbeianus), its skin, and its legs as potential food ingredients.

Food Chemistry, 2021
Frog farming systems do not take advantage of their byproducts, which represents health risks and environmental pollution. The present study aimed to evaluate the proximate composition, amino acid, and fatty acid profile of American Bullfrog byproducts ...

The Labyrinth of the American Bullfrog

2015
The labyrinth of the American bullfrog (Rana catesbiana) has been studied by aid of light and electron microscopy. Cell counts and sensory area mapping has been made and it has been shown that scanning electron microscopy is the most appropriate technique at present for cell counts.

Nonlinear Abundance-Area Relationship Underlying Processes of the American Bullfrog Invasion in the Zhoushan Archipelago, China.

Integrative Zoology
The small-island effect (SIE) has been used to quantify the increase of established non-native species richness with island area but has not yet been applied to explore the dynamics of non-native species abundance, which is important to develop timely ...

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.

Influence of temperature on biomarker responses and histology of the liver of American bullfrog tadpoles (Lithobates catesbeianus, Shaw, 1802) exposed to the herbicide Tebuthiuron.

Science of the Total Environment, 2021
Tebuthiuron (TBU) is a phenylurea herbicide that is extensively used in sugarcane fields. Owing to the low degradation rate, high water solubility, and leaching potential, TBU is believed to have harmful effects on aquatic organisms, such as anuran ...

Unbuckling the Buccal oscillator in the American Bullfrog

The FASEB Journal, 2016
The American Bullfrog is a remarkable model organism to study rhythm generation underlying breathing. It exhibits a breathing pattern that can be divided into four distinct ventilatory phases: lung‐priming, lung‐powerstroke, buccal‐dilation, and buccal‐constriction.
