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.

Morphological comparison of five species of poison dart frogs of the genus Ranitomeya (Anura: Dendrobatidae) including the skeleton, the muscle system and inner organs. [PDF]

open access: yesPLoS ONE, 2017
The morphology of larvae stages of most amphibians are often completely different than in adults. Tadpole descriptions have historically been based on external characters like morphometrics, color pattern and oral disc structure.

Riparian Amphibian and Reptile Assemblages in Streams Along a Forest Regeneration Gradient in the Ecuadorian Chocó

open access: yesBiotropica, Volume 58, Issue 6, November 2026.
ABSTRACT While primary forests are declining, regenerating habitats are becoming increasingly common. In fragmented environments, streams may function as corridors between forest remnants for riparian and aquatic species. However, the responses of stream‐associated species to forest regeneration remain understudied.

Frog tongue surface microstructures: functional and evolutionary patterns

open access: yesBeilstein Journal of Nanotechnology, 2016
Frogs (Lissamphibia: Anura) use adhesive tongues to capture fast moving, elusive prey. For this, the tongues are moved quickly and adhere instantaneously to various prey surfaces.

The influence of ultraviolet reflectance differs between conspicuous aposematic signals in neotropical butterflies and poison frogs

open access: yesEcology and Evolution, 2021
Warning signals are often characterized by highly contrasting, distinctive, and memorable colors. Greater chromatic (hue) and achromatic (brightness) contrast have both been found to contribute to greater signal efficacy, making longwave colored signals (

Flexible parental care in a songbird correlates with sex‐specific responses to seasonal phenology, mating opportunity and reproductive success

open access: yesJournal of Animal Ecology, Volume 95, Issue 7, Page 1178-1193, July 2026.
This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Urban–Wild Interface Diversity: A Comprehensive Checklist of Herpetofauna of Guayaquil, Ecuador

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Amphibians and reptiles in Guayaquil comprise multiple taxonomic orders and occur across conservation areas, forest remnants, and urban parks, including several endemic species and numerous taxa with type localities in the city. Although most species are globally classified as Least Concern, discrepancies between global and national threat assessments ...
