چکیده
Investigating environmental pollution is important to understand its impact on endangered species such as green turtles (Chelonia mydas). In this study, we investigated the accumulation and potential toxicity of selected persistent organic pollutants (POPs) naturally occurring MeO-PBDEs in liver, fat, kidney muscle (n = 30) different gender, size, year death, location health status. Overall, POP concentrations were low was highest liver lowest fat which likely due poor several animals, causing a remobilization lipids associated compounds. PCBs p,p’-DDE dominated profiles, relatively high MeO-PBDE (2′-MeO-BDE 68 up 192 ng/g lw, 6-MeO-BDE 47 79 lw) detected all tissues. Only few influences factors age, gender found. While compared other marine wildlife, biological equivalences obtained by screening tissue extracts using micro-EROD assay ranged from 2.8 356 pg/g values observed muscle, followed liver. This emphazises that pollutant mixtures found have cause dioxin-like effects these animals compounds should not be overlooked future studies.

The 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 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...

متن کاملSome Aspects of Electrolyte Excretion in the Green Turtle, Chelonia Mydas Mydas.
Except for the brief period of egg-laying, five species of turtle are strictly marine: namely, the green turtle (Chelonia mydas), the loggerhead turtle (Caretta carettd), Ridley's turtle (Lepidochelys olivacea), the hawksbill turtle (L. imbricatd) and the leatherback turtle (Dermochelys coriacea). Reptiles in the sea, like marine fish and marine birds, have a high intake of electrolytes; yet, a...
