Thyroid Function in the Salamander Amphiuma meansMoule, John William 04 1900 (has links)
The metabolism of iodide was investigated in the adult amphibian, Amphiuma means using an adaptation of a standard clinical radio-iodine technique. The thyroid uptake of I131 after intraperitoneal injection of a tracer does was linear on arithmetic plotting for seven days. The uptake then increased to a pronounced peak at seven days. / Thesis / Master of Science (MS)

Assisted reproductive technologies in male Ambystoma tigrinum with application to threatened newt speciesGillis, Amanda 07 August 2020 (has links)
The world is currently facing an amphibian extinction crisis and wild salamanders and newts (Order: Caudata) are the most disadvantaged with 52% of species threatened. Captive breeding programs are been established to act as assurance colonies, but they are overwhelmingly failing due to the lack of environmental cues to stimulate reproduction and other factors. Therefore, assisted reproductive technologies (ART) are being developed to overcome these barriers. This project expands upon the limited existing information on caudate ART through studies in the model species, Ambystoma tigrinum, for application to threatened species. Specific objectives included the characterization of motility longevity in artificially collected sperm samples, investigation of cryoprotective agents and freeze rates in sperm cryopreservation, and application of ART in three at-risk newt species. This study informs needed future advances in caudate ART protocols, especially sperm cryopreservation, and demonstrates their transferability to threatened species across families.
