The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines. [PDF]
J Exp Zool A Ecol Integr PhysiolABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens

Clashing in Murky Waters: On Amphibian Mosquito Suppression. [PDF]
Ecol EvolThis study compares the predator efficiency of common European amphibian species to common invertebrate mosquito predators. Focusing on the cosmopolitan mosquito Culex pipiens, known for transmitting pathogens like West Nile virus, we assessed predator rates, sex‐specific efficiency in amphibians, and the impact of predator presence on mosquito ...

The Medullary Audio-Vocal Network in the Toad Bombina orientalis. [PDF]
J Comp NeurolHypothetical network of audio‐vocal integration of motor neurons (twin circles) and interneurons (circles) in the medulla oblongata of the toad. ABSTRACT Anurans are an established paradigm to study vocal mechanisms in vertebrates. Regarding the motor patterns, airborne vocalization of most evolutionarily old anurans (Archaeobatrachia) resembles ...

Amphibian Strategies Against Attacks by Flies: Host-Specificity and Threats. [PDF]
Ecol EvolSpecies 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 ...

Perichordal Vertebral Column Formation in Rana kobai. [PDF]
J MorpholIn contrast to the previous study, centrum formation begins with a pair of ossification centers at the base of neural arches in Rana. At the early stage of intervertebral disc formation, a wedge‐like cartilage domain is observed posteroventral to the centrum. Evolutionary implications are discussed based on these observations.

Cryptic diversity in metropolis: confirmation of a new leopard frog species (Anura: Ranidae) from New York City and surrounding Atlantic coast regions. [PDF]
PLoS ONE, 2014 We describe a new cryptic species of leopard frog from the New York City metropolitan area and surrounding coastal regions. This species is morphologically similar to two largely parapatric eastern congeners, Rana sphenocephala and R. pipiens.

Testing the effectiveness of environmental DNA (eDNA) to quantify larval amphibian abundance
Environmental DNA, 2022 Environmental DNA (eDNA) monitoring is rapidly becoming an established approach for detecting the presence of aquatic organisms and may also be useful for indexing or estimating species abundance.
