Using Serially Collected Specimens to Investigate the Potential Population Genetic Consequences of Reported Declines in Eastern Woodland Salamanders

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Biodiversity is facing global change at an unprecedented rate; understanding how species respond to this accelerated change is important to inform future environmental and wildlife‐related policies. Serially collected specimens from natural history repositories can provide a unique window into how populations change over time and highlight further ...

Testing the Impact of Prey Presentation Method on the Feeding Kinematics of Terrestrial and Aquatic Ambystomatidae

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 10, Page 1150-1163, December 2025.
ABSTRACT In animal behavior, standardizing experimental protocols ensures a rigorous interpretation of the results. However, when working with multisource data, homogeneous standardization is often difficult to attain. This is the case for many studies on feeding kinematics where experimental protocols are carried out using similar but not identical ...

Salamander retina phospholipids and their localization by MALDI imaging mass spectrometry at cellular size resolution[S]

Journal of Lipid Research, 2011
Salamander large cells facilitated identification and localization of lipids by MALDI imaging mass spectrometry. Salamander retina lipid extract showed similarity with rodent retina lipid extract in phospholipid content and composition.

Re‐make, re‐model: evolution and development of vertebrate cranial lateral lines

Biological Reviews, Volume 100, Issue 6, Page 2237-2256, December 2025.
ABSTRACT Lateral lines are placodally derived mechanosensory systems on the heads and trunks of many aquatic vertebrates. There is evidence of lateral lines in the earliest known vertebrate fossils, and they exist in organisms with widely different craniofacial morphologies – including the presence or absence of jaws, external or internal nostrils, and

Evolution of the head-trunk interface in tetrapod vertebrates

eLife, 2016
Vertebrate neck musculature spans the transition zone between head and trunk. The extent to which the cucullaris muscle is a cranial muscle allied with the gill levators of anamniotes or is instead a trunk muscle is an ongoing debate.

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

Biological 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.

Myofibril-Inducing RNA (MIR) is essential for tropomyosin expression and myofibrillogenesis in axolotl hearts

Journal of Biomedical Science, 2009
The Mexican axolotl, Ambystoma mexicanum, carries the naturally-occurring recessive mutant gene 'c' that results in a failure of homozygous (c/c) embryos to form hearts that beat because of an absence of organized myofibrils.

A spatial transcriptomics comparison of the adult versus metamorphosed axolotl brain

Scientific Data
The Mexican axolotl (Ambystoma mexicanum) is an established model for studying tetrapod regeneration and development. Notably, axolotls exhibit remarkable brain regeneration as adults, a trait rarely observed in other adult vertebrates.

2D and 3D Echocardiography in the Axolotl (Ambystoma Mexicanum).

Journal of visualized experiments : JoVE, 2018
Cardiac malfunction as a result of ischemic heart disease is a major challenge, and regenerative therapies to the heart are in high demand. A few model species such as zebrafish and salamanders that are capable of intrinsic heart regeneration hold promise for future regenerative therapies for human patients.
