Buccal rhythmogenesis and CO2 sensitivity in Lithobates catesbeianus tadpole brainstems across metamorphosis. [PDF]
Bullfrog tadpoles ventilate both the buccal cavity and lung. In isolated brainstems, the midbrain/pons influences CO2 responsiveness and timing of lung ventilatory bursting, depending on larval development. However, little is known about midbrain/pons influences on buccal burst patterns.

Combating adult invasive American bullfrog Lithobates catesbeianus [PDF]
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 ...

Urbanization Facilitates Bullfrog Invasion Success and Exacerbates Native Amphibian Declines: A Natural Experiment From the COVID-19 Lockdown. [PDF]
This study investigates how urbanization amplifies the invasion of American bullfrogs and exacerbates declines in native amphibians in China's Yangtze Basin, using the COVID‐19 lockdown as a natural experiment. It finds that urban areas have higher bullfrog densities, likely due to human dispersal networks and permanent water sources, while native ...

Pathogenic fungus in feral populations of the invasive North American bullfrog in Argentina [PDF]
Nearly a third (32.4%) of the world?s amphibian species are either threatened with extinction or already extinct (1). The chytrid fungus Batrachochytrium dendrobatidis (Bd) (Chytridiomycetes: Ryzophydiales) (2) has been recognized as responsible for mass

Investigating differences across host species and scales to explain the distribution of the amphibian pathogen Batrachochytrium dendrobatidis. [PDF]
Many pathogens infect more than one host species, and clarifying how these different hosts contribute to pathogen dynamics can facilitate the management of pathogens and can lend insight into the functioning of pathogens in ecosystems.

Lithobates catesbeianus (American Bullfrog) oocytes: a novel heterologous expression system for aquaporins. [PDF]
Xenopus laevis oocytes are a valuable tool for investigating the function of membrane proteins. However, regulations around the world, specifically in Brazil, render the import of Xenopus laevis frogs impractical, and, in some cases, impossible. Here, as an alternative, we evaluate the usefulness of the North American aquatic bullfrog Lithobates ...

Multihost saprobes are facultative pathogens of bullfrog Lithobates catesbeianus eggs [PDF]
Pathogens that infect more than one host species create complex linkages in ecological communities. We tested whether saprobes that grow on multiple host species in aquatic systems can be facultative pathogens of amphibian eggs. We isolated oomycetes from dead arthropods, vertebrates, plant leaves, and frog eggs that coexisted in a small pond. Analysis

CHORUSING PATTERNS OF A DIVERSE ANURAN COMMUNITY, WITH AN EMPHASIS ON SOUTHERN CRAWFISH FROGS (LITHOBATES AREOLATUS AREOLATUS) [PDF]
Wildlife surveys have a critical role in conservation efforts and the collection of life history data. For anuran amphibians these surveys often focus on calling males.
