Genomic and Morphological Evidence Support Contemporary Three‐Way Interspecific Hybridization in Ranid Frogs

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
We investigated natural hybridization among three rapid frogs in eastern Oklahoma. Using genomic SNP data and cranial morphometrics, we confirmed the presence of hybrids exhibiting intermediate traits. Despite overlapping breeding phenologies, minimal introgression suggests hybrid fitness may be considerably lower than that of parental populations ...

Epidemiological landscape of Batrachochytrium dendrobatidis and its impact on amphibian diversity at global scale

open access: yesWildlife Biology, Volume 2025, Issue 5, September 2025.
Chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), is a major driver of amphibian decline worldwide. The global presence of Bd is driven by a synergy of factors, such as climate, species life history, and amphibian host susceptibility.

Pharmacological Effects of Two Novel Bombesin-Like Peptides from the Skin Secretions of Chinese Piebald Odorous Frog (Odorrana schmackeri) and European Edible Frog (Pelophylax kl. esculentus) on Smooth Muscle [PDF]

open access: yes, 2017
Bombesin-like peptides, which were identified from a diversity of amphibian skin secretions, have been demonstrated to possess several biological functions such as stimulation of smooth muscle contraction and regulation of food intake.

Temperature Variability and Salt Pollution Interact to Alter Subsequent Multi‐Parasite Susceptibility in Larval Amphibians

open access: yesFreshwater Biology, Volume 70, Issue 9, September 2025.
ABSTRACT Wild populations face unprecedented pressure from an assortment of anthropogenic environmental changes and parasites. We sought to understand how host–parasite interactions are affected by the interactive effects of multiple environmental stressors and subsequent parasite infection.

Opposite effects of climate and land‐use/cover change on Mediterranean herpetofauna: Insights from the southern Apennines

open access: yesAnimal Conservation, Volume 28, Issue 4, Page 501-514, August 2025.
Climate change (CC) and land‐use/cover change (LUCC) are threatening species worldwide, with amphibians and reptiles being particularly vulnerable. In Cilento, a highly biodiverse Mediterranean area in the southern Appenine protected by a National Park and 30 Natura 2000 Network sites, 11 amphibians and 16 reptiles could disappear in the future ...

A Review on Bradykinin-Related Peptides Isolated from Amphibian Skin Secretion [PDF]

open access: yes, 2015
Amphibian skin secretion has great potential for drug discovery and contributes hundreds of bioactive peptides including bradykinin-related peptides (BRPs). More than 50 BRPs have been reported in the last two decades arising from the skin secretion of
