Prevalence of Ranavirus Infection in Three Anuran Species across South Korea

open access: yesViruses, 2022
To cope with amphibian die-offs caused by ranavirus, it is important to know the underlying ranavirus prevalence in a region. We studied the ranavirus prevalence in tadpoles of two native and one introduced anuran species inhabiting agricultural and ...

Sexually dimorphic skin glands in the invasive species Lithobates catesbeianus (Anura: Ranidae)

open access: yesAmphibia-Reptilia, 2021
Abstract Males of most amphibian species possess specialized cutaneous glands, known as sexually dimorphic skin glands (SDSGs). SDSGs are usually clustered in specific body regions and are externally visible, but in some cases, external differences between males and females can be slight or absent, and the ...

Do Lithobates catesbeianus tadpoles acclimatise to sub-lethal copper?

open access: yesInternational Journal of Environment and Health, 2010
The aim of this work was to study the acute effects of short-term exposure (96 hours) to sub-lethal concentrations of copper (2 and 3 mg L−1) on ecotoxicological stress biomarkers in the aquatic stages of Lithobates catesbeianus (syn. Rana catesbeiana) larvae. To this end, the effects of copper on brain acetylcholinesterase, liver and gill catalase and

Feeds formulated with alternative ingredients for bullfrog tadpoles (Lithobates catesbeianus)

open access: yesResearch, Society and Development, 2022
Several foods are available for the formulation of rations in Brazil; however, the effectiveness of a few of these foods has been evaluated in diets for bullfrog tadpoles (Lithobates catesbeianus). This study aimed to evaluate alternative foods (worm meal, peeled banana, peeled pumpkin, and peeled avocado) with different levels of crude protein and ...

Effects of complex soundscapes on the occurrence of Anaxipha pallidula in isolated green spaces in Tokyo

open access: yesWildlife Biology, EarlyView.
Urban green spaces experience a mix of natural and anthropogenic noises, which could disrupt the vocal communication of several species. This study investigated how such complex soundscapes affect the occurrence of Anaxipha pallidula, which communicates through calls, focusing on both sound level and quality.

Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans

open access: yesIntegrative Zoology, EarlyView.
Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain

Changes in Site Occupancy of Marsh‐Breeding Frogs Are Associated With Surrounding Land Cover: Implications for Conservation Planning

open access: yesAnimal Conservation, EarlyView.
To help ensure the growth and persistence of frog populations, we quantified changes in frog occurrence as a function of concurrent changes in land cover in the surrounding landscape of eight marsh‐breeding frog species, or groups of species. We used data from the Great Lakes Marsh Monitoring Program delivered by Birds Canada at 377 sites across four ...
