Fossils Reveal Long-Term Continuous and Parallel Innovation in the Sacro-Caudo-Pelvic Complex of the Highly Aquatic Pipid Frogs

open access: yesFrontiers in Earth Science, 2019
Within the already peculiar Bauplan of anurans, pipid frogs have evolved an array of bizarre features that are commonly linked to their highly aquatic lifestyle. Among the latter, there are several distinctive sacro-caudo-pelvic features shared by extant

Does Chytridiomycosis Affect Tree Frog Attachment?

open access: yesDiversity, 2021
The pandemic disease chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), is a major threat to amphibian biodiversity. For most species, the exact mechanisms of chytridiomycosis that lead to negative population dynamics remain ...

Conservation of Glomerular Organization in the Main Olfactory Bulb of Anuran Larvae

open access: yesFrontiers in Neuroanatomy, 2020
The glomerular array in the olfactory bulb of many vertebrates is segregated into molecularly and anatomically distinct clusters linked to different olfactory functions. In anurans, glomerular clustering is so far only described in Xenopus laevis.

Enzymatic activity of bone markers on Lithobates catesbeianus (Shaw, 1802) growth during the ossification process

open access: yesBrazilian Journal of Biology, 2021
In order to better understand the ossification processes in anurans our study was carried out on tadpoles and adults of Lithobates catesbeianus. In this sense, we characterized the kinetic properties of alkaline phosphatase with p-nitrophenylphosphatase (
