Screening Salamanders for Symbionts
2022Microbial symbionts are broadly categorized by their impacts on host fitness: commensals, pathogens, and mutualists. However, recent investigations into the physiological basis of these impacts have revealed nuanced microbial influences on a wide range of host developmental, immunological, and physiological processes, including regeneration.

Heart induction in salamanders
Journal of Experimental Zoology, 1968AbstractHeart determination is a gradual, cumulative process involving inductive and suppressive interactions between the heart mesoderm and nearby embryonic tissues. Our analysis of heart determination in the California newt, Taricha torosa, includes defect and other in vivo experiments, and explants in epidermal vesicles and into hanging drops ...

Ancestry of unisexual salamanders
Nature, 1992In eastern North America there are populations of all-female salamanders that incorporate the nuclear genomes of two or three of four sympatric bisexual species. The hybrids can be diploid, triploid, tetraploid or pentaploid, and 18 different combinations have been reported. All hybrids require sperm from a sympatric male of one of the bisexual species

Tectectomy in the cyclopean salamander
Physiology & Behavior, 1991In an Ambystoma larva with both natural eyes removed and one eye grafted atop the head (Cyclops preparation), vision-dependent behavior usually recovers from the enucleation inherent in the operation, but the optically activated skin blanching reaction reappears in a very small number of instances.

Salamanders on the bench – A biocompatibility study of salamander skin secretions in cell cultures
Toxicon, 2017Salamanders have evolved a wide variety of antipredator mechanisms and behavior patterns, including toxins and noxious or adhesive skin secretions. The high bonding strength of the natural bioadhesives makes these substances interesting for biomimetic research and applications in industrial and medical sectors.

Epidermal xanthophores in a salamander
Canadian Journal of Zoology, 1973Non-melanophore pigment cells are generally restricted to the dermis. In contrast, the xanthophores, forming the dorsal yellow stripe of the long-toed salamander, Ambystoma macrodactylum, are located within the epidermis. They are underlain by dermal iridophores and melanophores.

On the scents of smell in the salamander
Nature, 2002Our sense of smell is based on a remarkable chemical-detection system that possesses high sensitivity, broad discriminability and plastic, yet stable, function. Understanding how olfactory stimuli translate into perception is a problem of daunting complexity.
