Recent climate change is an alarming threat to all living organisms including
green sea turtle, Chelonia mydas as a global rise in temperature may alter
environmental parameters in nest incubation. However, to what degree this
impacts has on green sea turtle has not been extensively studied in Malaysia.
Thus, this present study examines the effects of humidity in relation to digging
activity in green sea turtle hatchlings. Green sea turtle eggs were collected from
Chagar Hutang, Pulau Redang and subjected to different treatments (wet vs
dry) in an open-flow respirometry chamber. Result had shown that high water
content during nest incubation has positive impacts on green sea turtle
hatchlings’ morphology and subsequently increased their survivorship. Based
on these findings, we strongly suggest additional scientific research on the
impacts of humidity towards green sea turtle hatchlings where such information
would be beneficial to sea turtle hatchery in Malaysia.
