We report a new record of Lithobates catesbeianus (American bullfrog) from Argentina. L. catesbeianus was first introduced to San Juan Province 11 years ago in Calingasta Department, where the habitat is pre-cordilleran.

Bullfrog (Lithobates catesbeianus) farming system: water quality and environmental changes [PDF]
INTRODUCTION: Frog farming, if not well managed, may cause environmental damages. The use of antibiotics, the organic discharge and the introduction of exotic species can disseminate risks such as eutrophication, changes in the water quality and organic ...

Introduced bullfrogs are associated with increased Batrachochytrium dendrobatidis prevalence and reduced occurrence of Korean treefrogs. [PDF]
Bullfrogs, Lithobates catesbeianus, have been described as major vectors of the amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd). Bd is widespread throughout the range of amphibians yet varies considerably within and among populations in ...

Buccal rhythmogenesis and CO2 sensitivity in Lithobates catesbeianus tadpole brainstems across metamorphosis. [PDF]
Bullfrog tadpoles ventilate both the buccal cavity and lung. In isolated brainstems, the midbrain/pons influences CO2 responsiveness and timing of lung ventilatory bursting, depending on larval development. However, little is known about midbrain/pons influences on buccal burst patterns.

Combating adult invasive American bullfrog Lithobates catesbeianus [PDF]
American bullfrog Lithobates catesbeianus is considered as one of the world’s worst alien invasive species. Currently, the species is present over almost all continents and is suspected to cause substantial ecological damage. Knowledge about its population density, as well as catchability of the species with commonly used sampling gear, is very useful ...

Urbanization Facilitates Bullfrog Invasion Success and Exacerbates Native Amphibian Declines: A Natural Experiment From the COVID-19 Lockdown. [PDF]
This study investigates how urbanization amplifies the invasion of American bullfrogs and exacerbates declines in native amphibians in China's Yangtze Basin, using the COVID‐19 lockdown as a natural experiment. It finds that urban areas have higher bullfrog densities, likely due to human dispersal networks and permanent water sources, while native ...
