Epidemiological landscape of Batrachochytrium dendrobatidis and its impact on amphibian diversity at global scale

open access: yesWildlife Biology, Volume 2025, Issue 5, September 2025.
Chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), is a major driver of amphibian decline worldwide. The global presence of Bd is driven by a synergy of factors, such as climate, species life history, and amphibian host susceptibility.

Carcass yield and proximate composition of bullfrog (Lithobates catesbeianus)

open access: yesActa Scientiarum: Animal Sciences, 2015
This work evaluated five classes of weight of bullfrog (Lithobates catesbeianus) seeking to define the ideal slaughter weight for the species. We used 79 bullfrogs, distributed in a completely randomized design (class 1 < 100 g (n = 10); class 2 from 101 to 150 g (n = 17); class 3 from 151 to 200 g (n = 24); class 4 from 201 to 250 g (n = 14); and ...

Gonadal, body color, and genotoxic alterations in Lithobates catesbeianus tadpoles exposed to nonylphenol

open access: yesEnvironmental Science and Pollution Research, 2019
Endocrine disrupting chemicals are one of the most important factors contributing to worldwide amphibian decline. The 4-nonylphenol (NP) is a degradation product of several compounds, such as detergents and pesticides, affecting the aquatic environment.
