Future studies will examine the neuromuscular anatomy after their natural death to determine whether there are gross anatomical differences between metamorphosed axolotls and tiger salamanders. A DIALOGUE OF GAZES: METAMORPHOSIS AND EPIPHANY IN JULIO CORTAZARS. THE fact that a diet of mammalian thyroid will induce frog-tadpoles to metamorphose precociously. Due to the fact that axolotls are adapted to an aquatic environment, there may be losses and/or changes in developmental processes relative to other terrestrial ambystomoids that would not become phenotypically apparent until metamorphosis. Metamorphosis of Axolotl caused by Thyroid-feeding. Optimized axolotl (Ambystoma mexicanum) husbandry, breeding, metamorphosis, transgenesis and tamoxifen-mediated recombination Nat Protoc. We are comparing terrestrial axolotl locomotion to a close relative in the same genus that does normally metamorphose: the tiger salamander (Ambystoma tigrinum). The axolotl (Mexican salamander, Ambystoma mexicanum) has become a very useful model organism for studying limb and spinal cord regeneration because of its high regenerative capacity. This case study uses motion analysis of slow motion video to investigate the kinematics of terrestrial salamander locomotion. While observing these axolotls interact with their environment, we noticed that they walked in a seemingly clumsy and awkward fashion. We have three of these metamorphosed axolotls in our laboratory. Due to the rarity of metamorphosis, very little is known about the biology of terrestrial axolotls. Very rarely, some axolotls may spontaneously metamorphose into the terrestrial adult form. The purpose of this study was to investigate the influence of an ELF field on the forced metamorphosis of axolotls, which was induced with the thyroid hormone. They remain aquatic when they reach sexual maturity. 7 15:30 – 17:30 When Axolotls Metamorphose: The Kinematics of Salamanders That Shouldn’t Walk MATHEW, T* MASS, S SUNY New Paltz SUNY New Paltz (Ambystoma mexicanum) are neotenic salamanders that do not typically undergo metamorphosis.
