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

Abstract The biodiversity crisis necessitates spatially extensive methods to monitor multiple taxonomic groups for evidence of change in response to evolving environmental conditions. Programs that combine passive acoustic monitoring and machine learning are increasingly used to meet this need. These methods require large, annotated datasets, which are

Oviduct topography and irrigation in the bullfrog Lithobates catesbeianus (Shaw, 1802)
The bullfrog (Lithobates catesbeianus) is a species native to North America. It can reach about 20 cm in length and a body weight of 500 g. We used 30 adult frogs of the species Lithobates catesbeianus laying eggs to observe the oviduct. The animals were

Non-native Amphibian Pet Trade via Internet in Poland [PDF]
Overharvesting and trade in amphibian populations is one of the causes of their global decline. Online trade not only encourages the exploitation of an increasing number of rare and endangered amphibian species from all over the world but also ...

ABSTRACT Aim Many amphibians are experiencing declines, which are exacerbated for populations near range edges. To inform conservation strategies, we sampled sites of Blanchard's Cricket Frog (Acris blanchardi) at the northern periphery of their range to determine if modern declines are associated with genetic factors, delineate management units, and ...

Amphibian Strategies Against Attacks by Flies: Host‐Specificity and Threats
Species interactions between Diptera flies and amphibians play a significant role in tropical ecosystems, but their ecology and evolution remain understudied. This review explores the costs flies impose on amphibians, such as pathogen transmission and disruption of communication systems, and highlights the evolutionary strategies employed by both ...

The purpose of this project was to evaluate the efficacy of eDNA sampling to determine occupancy of Coeur d'Alene salamanders, an “imperiled” species in Montana. Previous methods used to identify occupied sites were haphazard with no measure of detection probability. Due to the unique habitat used by these salamanders (seeps and waterfall spray zones),

Characterisation of major histocompatibility complex class I genes in Japanese Ranidae frogs. [PDF]
The major histocompatibility complex (MHC) is a key component of adaptive immunity in all jawed vertebrates, and understanding the evolutionary mechanisms that have shaped these genes in amphibians, one of the earliest terrestrial tetrapods, is important.

This review synthesizes over 15 years of advancements in eDNA technology by systematizing standardized guidelines for sampling, extraction, and bioinformatics, thereby enhancing the reproducibility of eDNA‐based research. It highlights eDNA's transformative role in noninvasively detecting rare, endangered, and invasive species, as well as its value in ...
