Genetic structure and diversity of green turtles (chelonia mydas) from two rookeries in the South China Sea
Joseph, Juanita1, Hideaki Nishizawa2.
To understand the spatial and temporal genetic structure of green turtle
(Chelonia mydas) in South China Sea, we analyzed 178 samples collected from two
Malaysian rookeries (Redang Island and Sarawak) using the 800 base pair mitochondrial
DNA (mtDNA) control region sequences. Nucleotide diversity in Redang Island and
Sarawak was 0.027 ± 0.014 and 0.023 ± 0.011, respectively. The results confirmed the
spatial genetic differences between the two rookeries, and supported the natal philopatry
of turtles in South China Sea. However, comparison with 20-year-old data from previous
study showed no significant temporal differences, indicating that the genetic structures
of the populations are temporally stable. The two major rookeries for the green turtles
in this study are different in their genetic make-up, thus should be treated as different
management units to ensure their future survival.
