Observations on metamorphosing tadpoles of Hyalinobatrachium orientale (Anura: Centrolenidae) [PDF]

open access: yesPhyllomedusa: Journal of Herpetology, 2020
Observations on metamorphosing tadpoles of Hyalinobatrachium orientale (Anura: Centrolenidae). Metamorphosis, when anuran amphibians resorb their tails and remodel their mouthparts and internal organs, is a vulnerable stage in the frog’s life history. As

Bioacoustics characterization and habitat use of glass frogs in El Salvador

open access: yesCuadernos de investigación UNED, 2022
Introduction: Glass frogs occur from Mexico to South America, and, their taxonomy and distribution are currently debated. In El Salvador, the only species is thought to be Hyalinobatrachium fleischmanni, but it may instead be Hyalinobatrachium ...

New records of Chirripo Glass Frog, Hyalinobatrachium chirripoi (Taylor, 1958) (Anura: Centrolenidae) from Alajuela and Heredia, Costa Rica [PDF]

open access: yesRevista de biologia tropical, 2021
The Suretka glass frog, Hyalinobatrachium chirripoi, has been recently rediscovered in the south-eastern region of Costa Rica. This species was last reported in Costa Rica in the 1950’s. H. chirripoi is distin-guished from H. colymbiphyllum, which appears to be its most closely Costa Rican related taxon, by havingextensive webbing between fingers II ...

A third species of glassfrog in the genus Chimerella (Anura, Centrolenidae) from central Peru, discovered by an integrative taxonomic approach [PDF]

open access: yesEvolutionary Systematics, 2023
We studied the taxonomic status of glassfrogs collected in Departamento Huánuco, central Peru, which in the field were tentatively allocated to Chimerella, one of the twelve genera currently recognized in the family Centrolenidae.

Reproductive colonization of land by frogs: Embryos and larvae excrete urea to avoid ammonia toxicity

open access: yesEcology and Evolution, 2022
Vertebrate colonization of land has occurred multiple times, including over 50 origins of terrestrial eggs in frogs. Some environmental factors and phenotypic responses that facilitated these transitions are known, but responses to water constraints and ...
