Abstract
Talu Island in Prachuab Khiri Khan province is one of the protected area of the Plant
Genetic Conservation Project under the Royal Initiative of HRH Princess Maha Chakri
Sirindhorn. The island ecosystem is rich in biodiversity with a presence of important reptile
species, especially the hawksbill sea turtle, Eretmochelys imbricoto . The island is also
inhabited by many reptile species that play important roles in the ecosystem. A preliminary
field survey in March (dry season) revealed that eight species of reptile were found on the
island with the highest species richness of reptile in Order Squamata, Suborder Lacertilia.
Within this group, the garden fence lizard, Colotes versicolor, was the most commonly found
species, and thus used as an animal model in this study. A morphometry-based population
study showed that the snout-vent length of the lizard found on this island was within the
common range of the adult lizard found in other areas of Thailand. The sexual size
dimorphic data suggested that majority of lizards found in this study was male, and the
study period seemed to be within a reproductive season of this species. A morphometry
based health evaluation was conducted based on condition factor analysis of body weight
and body length relation. It was found that C. versicolor population found in this study has
the normal reference value of condition factor at 88.58 - 112.04. Using this normal
reference value to assess overall health of this population revealed that 8% of the
population has the condition factor above the normal range and 8% has the condition
factor below the range. This normal reference value could be further used as baseline data
for health status evaluation of C. versicolor in other seasons or in other environmental state
differed from the current situation.
Keywords: Colotes versicolor, condition factor, sexual size dimorphism

Abstract
Talu Island in Prachuab Khiri Khan province is one of the protected area of the Plant
Genetic Conservation Project under the Royal Initiative of HRH Princess Maha Chakri
Sirindhorn. The island ecosystem is rich in biodiversity with a presence of important reptile
species, especially the hawksbill sea turtle, Eretmochelys imbricoto . The island is also
inhabited by many reptile species that play important roles in the ecosystem. A preliminary
field survey in March (dry season) revealed that eight species of reptile were found on the
island with the highest species richness of reptile in Order Squamata, Suborder Lacertilia.
Within this group, the garden fence lizard, Colotes versicolor, was the most commonly found
species, and thus used as an animal model in this study. A morphometry-based population
study showed that the snout-vent length of the lizard found on this island was within the
common range of the adult lizard found in other areas of Thailand. The sexual size
dimorphic data suggested that majority of lizards found in this study was male, and the
study period seemed to be within a reproductive season of this species. A morphometry
based health evaluation was conducted based on condition factor analysis of body weight
and body length relation. It was found that C. versicolor population found in this study has
the normal reference value of condition factor at 88.58 - 112.04. Using this normal
reference value to assess overall health of this population revealed that 8% of the
population has the condition factor above the normal range and 8% has the condition
factor below the range. This normal reference value could be further used as baseline data
for health status evaluation of C. versicolor in other seasons or in other environmental state
differed from the current situation.
Keywords: Colotes versicolor, condition factor, sexual size dimorphism
