General and Comparative Endocrinology, 1981
Abstract The purification of thyrotropin from the pituitaries of two species of turtles was followed using a bioassay based on the uptake of radioiodide by the thyroid of the baby slider turtle, Pseudemys scripta . Conventional chromatographic techniques which had previously resulted in the separation of pituitary gonadotropins were used initially ...

Anesthesia in the green sea turtle, Chelonia mydas
American Journal of Veterinary Research, 1982SUMMARY Surgical anesthesia for green sea turtles weighing between 6 and 195 kg was achieved with the injectable anesthetics sodium pentobarbital, ketamine hydrochloride, and sodium thiopental. Induction of, duration of, and recovery from anesthesia varied among individual turtles.

Age prediction of green turtles with an epigenetic clock.
Molecular ecology resources, 2022Age is a fundamental life history attribute that is used to understand the dynamics of wild animal populations. Unfortunately, most animals do not have a practical or nonlethal method to determine age. This makes it difficult for wildlife managers to carry out population assessments, particularly for elusive and long-lived fauna such as marine turtles.

The diving behaviour of green turtles at Ascension Island
Animal Behaviour, 2000For six green turtles, Chelonia mydas, that had nested on Ascension Island in the South Atlantic, we used time-depth recorders to examine their diving behaviour during the subsequent internesting interval (10-12 days). All the turtles performed dives where they remained at a fixed depth for a long period, surfaced briefly and then dived to the same ...

Transoceanic Migrations of the Green Turtle
BioScience, 1964One aspect of the program of studies of marine turtles being carried out at the University of Florida' has been a small tagging project at Ascension Island, in the South Atlantic between Brazil and Africa. The aim was to test the assumption that the green sea turtle, Chelonia mydas, is capable of long-range open-water navigation.

Tagging Green Turtles, 1951–56
Nature, 1956ON three little islands off the south-west coast of Borneo, the Sarawak Turtle Board annually collects for sale or replants for hatching more than a million eggs of the green or edible turtle (Chelonia mydas Linn.)1. In 1951 we commenced marking experiments on this population.
