Variability of A Subterranean Prey-Predator Community in Space and Time

open access: yesDiversity, 2019
Subterranean habitats are characterized by buffered climatic conditions in comparison to contiguous surface environments and, in general, subterranean biological communities are considered to be relatively constant. However, although several studies have

Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods

open access: yesConservation Biology, EarlyView.
Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.

Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

open access: yesJournal of Zoology, EarlyView.
In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

open access: yesFEBS Open Bio, Volume 16, Issue 8, Page 1477-1490, August 2026.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

open access: yesAdvanced Robotics Research, Volume 2, Issue 4, August 2026.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

open access: yesThe Anatomical Record, Volume 309, Issue 8, Page 2151-2175, August 2026.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.

Eyespots in Automeris Moths Mimic Sympatric Owl Species (Lepidoptera: Saturniidae)

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Eyespot mimicry is a common anti‐predator strategy in moths, yet the mechanism underlying its effectiveness in Automeris remains unresolved. Using species distribution models, convolutional neural networks, and saliency mapping, we show that Automeris eyespots are visually confusable with sympatric owl eyes and that this similarity is concentrated in ...

Evolution of coprophagy and nutrient absorption in a Cave Salamander

open access: yesSubterranean Biology, 2017
The transition from carnivory to omnivory is poorly understood. The ability to feed at more than one trophic level theoretically increases an animal’s fitness in a novel environment.

Twenty‐Year Progress in Landscape Genetics of Tetrapods

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Geographic distribution of tetrapod landscape genetics between 2003 and 2025. ABSTRACT Landscape genetics, an interdisciplinary field integrating population genetics, landscape ecology, and spatial analytical techniques, has progressed significantly over two decades, yet systematic reviews of its application to tetrapods remain limited. Here, we review
