An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia)

open access: yesThe Anatomical Record, Volume 309, Issue 3, Page 674-699, March 2026.
Abstract 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

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.

Detecting mass mortality events in wildlife populations

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Reports in the literature of mass mortality events (MMEs) involving diverse animal taxa are increasing. Yet, many likely go unobserved due to imperfect detection and infrequent sampling. MMEs involving small, cryptic species, for instance, can be difficult to detect even during the event, and degradation and scavenging of carcasses can make ...

Deep‐soil sampling in Chile reveals a new elateroid beetle family, Badmaateridae fam. nov. (Coleoptera)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
Genomic data support the definition of a new elateroid family, Badmaateridae fam. nov., with Badmaater chilensis gen. nov. sp. nov. as the only representative. Badmaateridae is sister to an extensive clade containing fireflies, soldier beetles, net‐winged beetles and click beetles.

Microanatomy of Dermal Roofing Bones in the Skull of Pipoid Frogs

open access: yesJournal of Morphology, Volume 286, Issue 12, December 2025.
The cranial bone microanatomy in extant and extinct aquatic pipoids and phylogenetically distant aquatic anurans were analyzed. Micro‐CT data revealed no significant differences in bone thickness and cross‐sectional area among groups, that present similar aquatic lifestyles.

Review of the tetrapod skull–neck boundary: implications for the evolution of the atlas–axis complex

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2435-2470, December 2025.
ABSTRACT This review describes variation in modern and fossil occiput–atlas–axis complex anatomy of total group Tetrapoda with the aim of documenting the range of structural variation throughout their evolutionary history to establish grounds for comparison of the complex between tetrapod clades.

Disentangling the interrelations of body mass, egg deposition site, climate and microhabitat use in frogs and salamanders

open access: yesEcography, Volume 2025, Issue 11, November 2025.
Amphibians exhibit a large diversity in reproductive and developmental strategies, which in turn are linked to their body size, life history and habitat. Here, we explore why terrestrial egg laying frogs are on average smaller than aquatic egg laying ones and whether this pattern also exists in salamanders.

Persistence of sub‐clinical infections caused by Batrachochytrium dendrobatidis in stream anurans in South Asia

open access: yesEcosphere, Volume 16, Issue 11, November 2025.
Abstract Chytridiomycosis is caused by Batrachochytrium dendrobatidis (Bd) and contributes significantly to amphibian declines globally. It has affected more than 500 amphibian species on five continents. In South Asia, the Western Ghats is an amphibian biodiversity hotspot; however, the population status of anurans and their burden of chytridiomycosis
