Green turtle (Chelonia mydas) genetic diversity at Paranaguá Estuarine Complex feeding grounds in Brazil
Sea turtles are marine reptiles that undertake long migrations through their life, with limited information regarding juvenile stages. Feeding grounds (FGs), where they spend most of their lives, are composed by individuals from different natal origins, known as mixed stock populations. The aim of this study was to assess genetic composition, natal origins and demographic history of juvenile gr...
متن کاملThe Biology of Basking in the Green Turtle (chelonia Mydas)
The green turtle (Chelonia mydas) is the only species of marine turtle known to atmospheric bask, whereby large numbers of turtles remain hauled out on shore. Historic records indicate that basking was once a common phenomenon, yet coastal development may have reduced basking populations to only a few remote areas worldwide. Our study aims to determine physiological roles that this behavior fus...
متن کاملFibropapillomatosis in green turtles Chelonia mydas in Brazil: characteristics of tumors and virus.
Fibropapillomatosis (FP) is a benign neoplasia that affects physiological functions of sea turtles and may lead to death. High prevalence of FP in sea turtle populations has prompted several research groups to study the disease and the associated herpesvirus, chelonid herpesvirus 5 (ChHV5). The present study detected and quantified ChHV5 in 153 fibropapilloma samples collected from green turtle...
متن کاملHearing in the giant sea turtle, Chelonia mydas.
Measurement were made of the cochlear potentials in three specimens of the giant sea turtle, Chelonia mydas, in response to both aerial and mechanical stimulation of the ear. The results show maximum sensitivity in the region of 300 to 400 Hz, with a rather rapid decline in sensitivity for lower and especially for higher tones. The upper limit for the observation of cochlear potentials without ...
متن کاملBasking Behavior of the Hawaiian Green Turtle (Chelonia mydas)l
Observations were made on green turtles basking on the white sand beaches at French Frigate Shoals in the northwestern Hawaiian Islands. The highest rectal temperature recorded from the basking turtles was 31.3°C, but the surface temperature of the carapace attained values as great as 42.8°C. During basking, the turtles flipped sand onto their carapaces, but they did not appear to orientate the...
