Combating adult invasive American bullfrog Lithobates catesbeianus [PDF]

open access: yesEuropean Journal of Wildlife Research, 2014
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 ...

Oxalate nephropathy in free-living American bullfrog tadpoles [PDF]

open access: yesDiseases of Aquatic Organisms, 2015
In February 2014, wild American bullfrog Lithobates catesbeianus tadpoles from an artificial pond in the Kyusyu region, Japan, presented with coelomic and subcutaneous edema and erythema within the skin. A pathological examination of 57 tadpoles of American bullfrogs in the region was conducted to evaluate the disease.

Invasive American Bullfrogs Age, Body Size, and Sexual Size Dimorphism Geographical Variation in Northwestern China

open access: yesDiversity, 2022
Invasive species impact both the local biota and human economies and are a very serious threat to biodiversity. The American bullfrog was initially introduced into northwestern China and many other sites for aquacultural purposes. Then, the frogs escaped
