Historical Climate and Biome Association Drove Phylogeographic Patterns in the Dwarf Swamp Frog (Anura: Leptodactylidae)

open access: yesZoologica Scripta, EarlyView.
ABSTRACT South America, a region with high biodiversity, has been profoundly shaped by geological events during the Miocene and Pliocene, as well as by climatic changes in the Pleistocene, leading to complex phylogeographic patterns. The diverse biomes and the biotic exchanges between them, particularly between the Amazon and the Cerrado, have ...

An evaluation of transcriptome‐based exon capture for frog phylogenomics across multiple scales of divergence (Class: Amphibia, Order: Anura)

open access: yesMolecular Ecology Resources, 2016
Custom sequence capture experiments are becoming an efficient approach for gathering large sets of orthologous markers in nonmodel organisms. Transcriptome‐based exon capture utilizes transcript sequences to design capture probes, typically using a ...

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene‐Edited Xenopus Tadpoles

open access: yesJournal 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.

Intradermal infections by chigger mites (Hannemania spp.) in the Andean frog Telmatobius atacamensis (Anura, Telmatobiidae) [PDF]

open access: yes, 2015
Here, we report the infection of adults of the Andean frog Telmatobius atacamensis (Anura, Telmatobiidae) by leeuwenhoekiid mites of the genus Hannemania and describe the histological characteristics of the normal and infected skin and the mite's larval ...

Multiple anti-predator mechanisms in the red-spotted Argentina Frog (Amphibia: Hylidae) [PDF]

open access: yes, 2017
Anurans employ a wide variety of anti-predator mechanisms to defend themselves. In casque-headed hylids, defence is thought to be a complex combination of several anti-predator mechanisms. However, the defence traits of only a few species are known; some

Amphibian Strategies Against Attacks by Flies: Host‐Specificity and Threats

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Species interactions between Diptera flies and amphibians play a significant role in tropical ecosystems, but their ecology and evolution remain understudied. This review explores the costs flies impose on amphibians, such as pathogen transmission and disruption of communication systems, and highlights the evolutionary strategies employed by both ...

Concentrated evolutionary novelties in the foot musculature of Odontophrynidae (Anura: Neobatrachia), with comments on adaptations for burrowing.

open access: yesZootaxa, 2017
We studied the foot musculature of the fossorial family Odontophrynidae (composed of the genera Macrogenioglottus, Odontophrynus, and Proceratophrys) plus several outgroup taxa from Hyloidea and other burrowing taxa from across Anura.
