Samples of the adult geckos were collected monthly from November, 2009 to October, 2010 and brought to our laboratory in Zhaoqing University. The geckos were measured, weighed and freezing-killed at -20 °C, and then separated into carcasses, livers and tails. The three components were dried to constant mass at 65 °C, weighed and fro- zen-preserved for later determination
