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 .
Habitat fragmentation occurs when habitats are isolated by habitat modification, such as when a small area of forest is completely surrounded by agricultural fields. Small populations that survive within such fragments are often susceptible to inbreeding, genetic drift, or extinction due to small fluctuations in the environment. [16]

Two burnsi morphs, a green morph, and a brown morph of the northern leopard frog Brown morph northern leopard frog in a wood chip pile in Iowa. The northern leopard frog has several different color variations, with the most common two being the green and the brown morphs, with another morph known as the burnsi morph. Individuals with the burnsi morph coloration lack spots on their backs, but ...
The annual global trade in the American bullfrog (Rana catesbeiana), mostly farmed in China, varies between 1200 and 2400 tonnes. [ 219 ] The mountain chicken frog , so-called as it tastes of chicken, is now endangered, in part due to human consumption, and was a major food choice of the Dominicans . [ 220 ]
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.
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.
[21] [22] The bullfrog often escapes captivity and can establish feral populations where it may introduce the disease to new areas. [8] It has also been shown that B. dendrobatidis can survive and grow in moist soil and on bird feathers, suggesting that B. dendrobatidis may also be spread in the environment by birds and transportation of soils ...
