Abstract
To identify the biological characteristics of Wolter lizard (Takydromus wolteri), this study was conducted from March 2011 to August 2012 in the areas of Geumoreum located in Hangyeong-myeon, and Saebyeoloreum located in Aewol-eup and in the zoological laboratory in Jeju National University, South Korea. Food source, enemies, activity period, breeding period, spawning period, spawning size in a clutch, biological traits of eggs and hatching periods were investigated. As a result of the study, it was found that T. wolteri eats Gryllidae, Araneina, Orthoptera, Diptera, Hymenoptera and Lepidoptera, but not Coleoptera, Formicidae, Oligochaeta. By observing the vicinities of T. wolteri habitats, it was seen that the natural enemies of T. wolteri were Elaphe dione, Amphiesma vibakari ruthveni, Sibynophis chinensis, Rhabdophis tigrinus, Gloydius ussuriensis, Corvus macrorhynchos, Streptopelia orientalis, Falco tinnunculus, Pica pica sericea, Lanius bucephalus, Hypsipetes amaurotis. Activities started in mid-March and hibernation started between late November and early December. Mating period was seen to run between May to June, breeding was May to August, and spawning was June toAugust. The average weight of spawned eggs (n = 12) was 0.3g; size was 9.5 × 7.2 mm; and the average fecundity of the clutch was 5 (with range 3~7). Incubation period was 18~20 days. The results would be useful as the necessary material for preparing conservation and management plans for T. wolteri habitats that depend on the changes in the habitat environment.
