چکیده انگلیسی
Red-spotted tokay geckos, Gekko gecko, are distributed mainly in Southeast Asia. They are a traditional Chinese medicine, with the massive hunting for exports dramatically decreasing their numbers. Information on the genetic diversity of these geckos in Southeast Asia is very limited. This study aims to explore intrapopulation and interpopulation genetic variation and the genetic structure of 16 populations collected from different localities in Thailand, Lao People's Democratic Republic, and Cambodia using multilocus enzyme electrophoresis. Relatively high genetic diversity occurred at both the intrapopulation and interpopulation levels. Genetic differentiation with FST values ranging between 0.006-0.892 was found. Five distinct genetic groups of the red-spotted tokay populations could be classified. A group of populations from northern Thailand showed the highest genetic differentiation from the other groups. Moreover, there was a substantial genetic subdivision depending on the genetic groups with FCT = 0.664 and FSC = 0.185. This genetic structure is related to geographical distribution and distance between populations, R2 = 0.5614, p < 0.001. Our findings of pronounced genetic structuring and the concomitant conservation genetic consequences if further population loss occurs mean that management actions should therefore focus on the conservation of all of the main sites where tokay geckos still occur.
