Comparative analysis of amphibian genomes: An emerging resource for basic and applied research [PDF]

Molecular Ecology Resources, Volume 25, Issue 1, January 2025.
Abstract Amphibians are the most threatened group of vertebrates and are in dire need of conservation intervention to ensure their continued survival. They exhibit unique features including a high diversity of reproductive strategies, permeable and specialized skin capable of producing toxins and antimicrobial compounds, multiple genetic mechanisms of ...

Validation and development of eDNA metabarcoding primers for comprehensive assessment of Chinese amphibians [PDF]

Integrative Zoology, Volume 20, Issue 3, Page 504-519, May 2025.
eDNA metabarcoding, using various primer sets, effectively amplified 83 amphibian species from China, showcasing its potential for biodiversity assessments. However, optimizing amphibian‐specific primers is crucial due to occasional non‐amphibian amplification.

Distinct Gut and Skin Microbiomes of a Carnivorous Caecilian Larva (Ichthyophis bannanicus) Show Ecological and Phylogenetic Divergence from Anuran Tadpoles [PDF]

Microorganisms
The amphibian microbiome plays a vital role in host health, yet the bacterial communities of caecilians (Order: Gymnophiona) remain largely uncharacterised.

CaecilianTraits, an individual level trait database of Caecilians worldwide [PDF]

Scientific Data
Functional traits differ among species, which determine the ecological niche a species occupies and its ability to adapt to environment. However, differences in traits also exist at intraspecific level.

Circadian rhythm and surface activity in soil-dwelling caecilians (Amphibia: Gymnophiona) [PDF]

Scientific Reports
The degree to which burrowing, soil-dwelling caecilian amphibians spend time on the surface is little studied, and circadian rhythm has not been investigated in multiple species of this order or by manipulating light–dark cycles.

Diversity and Molecular Evolution of Antimicrobial Peptides in Caecilian Amphibians [PDF]

Toxins
Antimicrobial peptides (AMPs) are key molecules in the innate immune defence of vertebrates with rapid action, broad antimicrobial spectrum, and ability to evade pathogen resistance mechanisms.

Phylogenetic relationships of Indian caecilians (Amphibia: Gymnophiona) inferred from mitochondrial rRNA gene sequences [PDF]

, 2002
India has a diverse caecilian fauna, including representatives of three of the six currently recognized families, the Caeciliidae, Ichthyophiidae, the endemic Uraeotyphlidae, but previous molecular phylogenetic studies of caecilians have not included ...

Molecular evolution of HoxA13 and the multiple origins of limbless morphologies in amphibians and reptiles

Genetics and Molecular Biology, 2015
Developmental processes and their results, morphological characters, are inherited through transmission of genes regulating development. While there is ample evidence that cis-regulatory elements tend to be modular, with sequence segments dedicated to ...

Sesamoids in Caudata and Gymnophiona (Lissamphibia): absences and evidence

PeerJ, 2020
An integrative definition of sesamoid bones has been recently proposed, highlighting their relationship with tendons and ligaments, their genetic origin, the influence of epigenetic stimuli on their development, and their variable tissue composition.

Mitochondrial Evidence on the Phylogenetic Position of Caecilians (Amphibia: Gymnophiona) [PDF]

Genetics, 2000
AbstractThe complete nucleotide sequence (17,005 bp) of the mitochondrial genome of the caecilian Typhlonectes natans (Gymnophiona, Amphibia) was determined. This molecule is characterized by two distinctive genomic features: there are seven large 109-bp tandem repeats in the control region, and the sequence for the putative origin of replication of ...
