EARTH DAY for GLOBALWARMING

Based on the results of turtle research at the University of Udayana Bali, the female turtle for more than half the population of turtles in habitats of East Java, Papua, and the Lesser Sunda. This makes the threat to the balance of the turtle population.

Shrinking of the number of turtles jan this challenge because of climate change with the temperature getting warmer and less controlled development around the coast. While the success of sea turtle eggs into the male depends on air temperature in the sand beach that is not more than 28 degrees Celsius to 29 degrees celsius and under trees around the beach.

"Human nature and to improve habitat for these turtles need to continue to cultivate. Because, not easy to rejuvenate the damaged beach, so the turtle-turtle can lay eggs and hatch well," said Marine Turtle Coordinator for Training and Research Center University of Udayana drh Adnyana IB Windia PhD, at Denpasar.

He added, turtle hatching success rate fell from 90 percent to 70 percent every year since the last 10 years. For example in the Bird's Head (Papua), egg hatching success began to decline from 500 fish per year.

According to Windia, fix the coast due to abrasion or erosion by adding sand from other beaches is not always good for breeding turtles. "Including turtle conservation was not all positive, if not accompanied by improving the original nature as devegetasi. The trees around the beach for turtle protection," he said.

Research conducted since October 2008 until now working together with WWF. In the study, researchers collected about 400 Udayana tail turtle samples of saliva taken, cukilan skin, and blood for genetic testing. Funds spent approximately USD 1.5 billion.

In the study also found a turtle genetic differences from one region to another, both turtle (Lepidochelys oliviacea), green turtle (Chelonia mydas), and star fruit turtle (Dermochelys coriacea). Although turtles like to come to the other shore, he was still laying in their places of origin.

This Windia explained during the turtle is considered to have a similar genetic and can spawn anywhere. In the study revealed, the turtle has a different genetic and found for the region of East Java, Sunda Islands, and Papua, there are three groups.

Three genetic groups of turtles are the first group in the Bird's Head Beach (Papua) and Arafuru Sea. The second group is divided into two, namely East Java-Bali, Central Java (Cilacap), East Java and Western Australia. The third group was in East Kalimantan until the Sulu Sea.

He hopes this research can be useful for further research. "We want the public to understand and know about the turtle so as not doing things in vain. Turtle conservation is not only limited to not eat and steal eggs or meat course. Habitat and a damaged environment also needs to be fixed," said Windia.

On the Island of the Gods, the people began to not eat turtle meat, especially in religious ceremonies or as prohibited by the government. Average Kompyang, traders satay wrap in Denpasar, admitted the difficulty of getting back turtle meat.
