Post‐metamorphic growth partially compensates for the effects of climate‐driven stressors on juvenile frog performance

Ecosphere, Volume 16, Issue 2, February 2025.
Abstract Human‐induced climate change, land use changes, and urbanization are predicted to dramatically impact landscape hydrology, which can have devastating impacts on aquatic organisms. For amphibians that rely on aquatic environments to breed and develop, it is essential to understand how the larval environment impacts development, condition, and ...

The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines. [PDF]

J Exp Zool A Ecol Integr Physiol
ABSTRACT 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 Evol
This 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 ...

Prevalence of the pathogenic chytrid fungus, Batrachochytrium dendrobatidis, in an endangered population of northern leopard frogs, Rana pipiens. [PDF]

BMC Ecol, 2010
Background Emerging infectious diseases threaten naïve host populations with extinction. Chytridiomycosis, an emerging infectious disease of amphibians, is caused by the pathogenic fungus Batrachochytrium dendrobatidis (Bd) and has been linked to global ...

The Medullary Audio-Vocal Network in the Toad Bombina orientalis. [PDF]

J Comp Neurol
Hypothetical 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 Evol
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 ...

Perichordal Vertebral Column Formation in Rana kobai. [PDF]

J Morphol
In 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.

Follow-up ecological studies for cryptic species discoveries: Decrypting the leopard frogs of the eastern U.S. [PDF]

PLoS ONE, 2018
Cryptic species are a challenge for systematics, but their elucidation also may leave critical information gaps about the distribution, conservation status, and behavior of affected species. We use the leopard frogs of the eastern U.S. as a case study of

In vivo muscle force and muscle power during near-maximal frog jumps. [PDF]

PLoS ONE, 2017
Frogs' outstanding jumping ability has been associated with a high power output from the leg extensor muscles. Two main theories have emerged to explain the high power output of the frog leg extensor muscles, either (i) the contractile conditions of all ...

Localized carry‐over effects of pond drying on survival, growth, and pathogen defenses in amphibians

Ecosphere, 2022
Climate change is increasing variability in precipitation patterns in many parts of the globe. Unpredictable changes in water availability can be particularly challenging for organisms that rely on precipitation‐fed water sources for completing their ...
