An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia) [PDF]
The Anatomical RecordAbstract Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake‐like or worm‐like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live in aquatic or semi‐aquatic environments, either as larvae or adults.

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene‐Edited Xenopus Tadpoles [PDF]
Journal of Pineal Research, Volume 78, Issue 2, March 2026.ABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.

A Review of the Scale and Sustainability of the Consumption and Trade of Anuran Species in Africa [PDF]
Ecology and Evolution, Volume 16, Issue 3, March 2026.ABSTRACT Within Africa, collection and trade of anurans is often recorded as single‐site case studies, making it difficult to accurately understand the scale of use, its livelihood importance, and impact on species. We conducted a systematic review to: compile literature on anuran uses in Africa; identify the species and ecoregions involved; and ...

Mitochondrial Phylogenomics and Genome Evolution in Anura: Insights From Structure and Gene Order Rearrangements [PDF]
Ecology and Evolution, Volume 16, Issue 4, April 2026.By analyzing 277 anuran mitochondrial genomes, this study reconstructs a robust phylogeny for frogs and toads, tracing their origins to the Triassic and major radiations to the Cretaceous‐Neogene. The research identifies 58 distinct gene arrangement patterns, providing a novel evolutionary framework.

Seasonal Analysis of the Male Reproductive Tract and Germ Cell Proliferation in Leptodactylus podicipinus (Anura) [PDF]
Journal of Morphology, Volume 286, Issue 8, August 2025.Box 1: Anuran reproductive morphology and dynamics are complex and diverse. Box 2: It is essential to comprehend reproductive morphology in a broad sense and simultaneously at different organizational levels. Box 3: The study characterizes the components of the male reproductive tract and assess testicular cell proliferation throughout the reproductive

Quantifying exposure of amphibian species to heat waves, cold spells, and droughts [PDF]
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Globally, amphibians face severe threats, such as climate change and associated extreme events. Our goal was to quantify global amphibian exposure to 3 classes of extreme events: heat waves, cold spells, and droughts. We used the MERRA‐2 extreme climate events data and the standardized precipitation–evapotranspiration index database to ...

Amphibians and Reptiles Exhibit Different Ecological and Evolutionary Spatial Patterns in the Amazon Basin [PDF]
Ecology and Evolution, Volume 15, Issue 3, March 2025.This study investigates the spatial variability of ecological and evolutionary patterns in amphibian and reptile lineages within the Amazon Basin. Our findings highlight distinct diversity patterns across lineages and ecoregions. ABSTRACT Understanding spatial variability in ecological and evolutionary patterns is key to Amazonian biodiversity ...
