Control of lung ventilation following overwintering conditions in bullfrogs,Lithobates catesbeianus [PDF]

Journal of Experimental Biology, 2016
Ranid frogs in northern latitudes survive winter at cold temperatures in aquatic habitats often completely covered by ice. Cold-submerged frogs survive aerobically for several months relying exclusively on cutaneous gas exchange while maintaining temperature-specific acid-base balance.

Size‐Dependent Habitat Selection in a Tropical Freshwater Crayfish: Preference for Vegetated Refugia

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Young freshwater crayfish need shelter to survive, but it is often unclear whether they actively choose safe habitats or simply remain where they are found. We show that craylings and juvenile red claw crayfish prefer vegetated habitats over bare sand or gravel, and that this preference becomes stronger as crayfish grow.

Tracking viral particles in the intestinal contents of the American bullfrog, Lithobates catesbeianus, by Transmission Electron Microscopy

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
Feces are an important viral agent elimination route for infected carrier animals and in aquatic organisms these pathogenic agents can very rapidly propagate due to the habitation environment. The objective of this work is to track viral particles in the

Differential Susceptibility May Not Drive Chytridiomycosis Related Declines in Multi‐Host Amphibian Communities

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We investigated how Batrachochytrium dendrobatidis (Bd) affects multi‐host amphibian communities in Tasmania, Australia. Despite differential susceptibility, we found no evidence of population declines in susceptible species, suggesting that current environmental conditions may buffer communities against Bd impacts.

Primeiro relato de Lernaea cyprinacea (Copepoda: Lernaeidae) em girinos e rãs recém-metamorfoseadas em populações selvagens de Lithobates catesbeianus (Anura: Ranidae) na Argentina

Phyllomedusa: Journal of Herpetology, 2016
Lernaea cyprinacea é um copépode ectoparasita que pode causar a morte do hospedeiro devido às hemorragias, ulcerações e infecções secundárias que provoca. Lernaea cyprinacea está amplamente distribuída na Argentina.

Policy Recommendation on the Restriction on Amphibian Trade Toward the Republic of Korea

Frontiers in Environmental Science, 2020
Amphibian diseases and invasive amphibian species are both generally introduced through the wildlife trade, either for human consumption or for the pet trade. However, adequate regulations can prevent such introductions.

Many roads to reservoirs? How susceptibility and shedding shape host competence in amphibians

Functional Ecology, Volume 40, Issue 3, Page 585-598, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Host competence—the ability to acquire, harbour and transmit infections—drives pathogen spread and persistence in multi‐host communities. Evaluating species‐specific competence is critical for predicting transmission, particularly for generalist fungal pathogens like ...

Changes in morphology over time due to denaturing agents in an ethanol and camphor solution [PDF]

Natural History Collections and Museomics
The ethanol collections of the Africamuseum require an approved denaturing agent, that can be used to top-up containers in which, historically, camphor-denatured ethanol has been used.

Estimating spatially varying occupancy trends for multi‐scale conservation: An amphibian case study in the midwestern United States

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
Our spatial modelling approach allows practitioners to estimate trends across multiple spatial scales to inform local and regional management priorities, particularly when summarizing trends within key areal units used for conservation planning. Our framework can be used to identify hotspots of decline across multiple sympatric species for targeted ...

Lithobates Catesbeianus (American Bullfrog)

, 2017
Three adult males and two females collected alive. Lithobates catesbeianus is native from southeastern Canada, much of the central and eastern United States, and northeastern Mexico, and has also been reported in another 41 countries throughout the world, where it has been introduced for commercial purposes (Barrasso et al. 2009. South Am. J. Herpetol.
