The American bullfrog (Lithobates catesbeianus), often simply known as the bullfrog in Canada and the United States, is a large true frog native to eastern North America. It typically inhabits large permanent water bodies such as swamps , ponds , and lakes .
The arrival of the American bullfrog has been harmful to many native species, but Heinzman said that the northern leopard frog's populations are alarmingly low, with only one site in the State ...
No matter the type, all invasive species can negatively impact native ecosystems. Across the United States, pesky, unwanted plants and insects can insert themselves in ecosystems and damage their ...
Once released into the aquatic environment, zoospores travel less than 2 cm (0.8 in) within 24 hours before they encyst. [21] The limited range of B. dendrobatidis zoospores suggest some unknown mechanism exists by which they transmit from one host to the next, [21] which can involve the pet trade, and especially the American bullfrog.

Lithobates, commonly known as the bullfrogs, is a genus of true frogs, of the family Ranidae. [1] The name is derived from litho- (stone) and the Greek bates ( βάτης , one that treads), meaning one that treads on rock, or rock climber.
The exception to this is where the American bullfrog is not native and has been introduced. In these ecosystems, American bullfrogs can decimate local amphibian populations, upset ecosystem balance, and have negative impacts on other species of wildlife as well.
The population of the mountain chicken frog, once abundant in the Caribbean, has dropped by over 99% in 20 years due to a deadly fungal disease.
American bullfrogs (Lithobates catesbeianus), also widely distributed, are also thought to be carriers of the disease due to their inherent low susceptibility to B. dendrobatidis infection. [ 21 ] [ 22 ] The bullfrog often escapes captivity and can establish feral populations where it may introduce the disease to new areas. [ 8 ]
