Histological and Gene Expression Analyses of the Arm and Finger Macroglands of Two Hyloxalus Frogs (Dendrobatidae)

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Chemical communication during courtship is well documented in salamanders and newts, but its role in frogs is less understood. In some Neotropical poison frogs, males exhibit specialised mucous glands (SMGs) in the hand integument that express high levels of sodefrin precursor‐like factors (SPFs), an amphibian pheromone. Some species also show

Longevity, Age‐Specific Survival, and Mean Generation Time of Rana muscosa: Implications for Conservation of Possibly the Longest‐Lived Ranid Frog

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We examined 22 years of mark and recapture data for an endangered amphibian (Rana muscosa) and estimated longevity, age‐specific survival, and mean generation time. The oldest individual was determined to be at least 21 years old. ABSTRACT Life history strategies vary widely among species and play a vital role in extinction risk, especially in a ...

Age Structure and Size Variation in Three Closely Related Species of Casque‐Headed Frogs of the Genus Trachycephalus (Hylidae: Lophyohylini)

open access: yesActa Zoologica, Volume 106, Issue 4, Page 485-492, October 2025.
ABSTRACT Parreira. I.P. 2025. Age structure and size variation in three closely related species of casque‐headed frogs of the genus Trachycephalus (Hylidae: Lophyohylini)—Acta zoologica (Estocolmo). This study provides insights into longevity, sexual maturity and growth curves in closely related casque‐headed treefrogs distributed across distinct ...

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.

Effects of hydroperiod on metamorphosis in \u3ci\u3eRana sphenocephala\u3c/i\u3e [PDF]

open access: yes, 2001
Hydroperiod, the time a temporary pond holds water, is an important factor influencing recruitment in amphibian populations and structuring amphibian communities.

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.
