  • The lacertid lizard Takydromus wolteri widely distributed in South Korea, but intraspecific diversity of this species was not almost studied. T. wolteri represented by 8 specimens collected from 5 localities were analyzed by the Randomly Amplified Polymorphic DNA (RAPD) method with 28 random decamer primers and the phenogram constructed by using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) method based on RAPD data. The populations of T. wolteri using in this paper were collected from Gyeonggi-do, Chungcheongbuk-do, Jeju-do, Jeollanam-do and Gyeongsangnam -do in South Korea. Among 68 different bands detected in RAPD analysis, 59 bands (87%) showed polymorphism. The phenogram showed that the populations of T. wolteri were grouped into two. These results suggest that T. wolteri were supported intraspecific diversity.

  • The present paper attempts to elucidate the taxonomic status of five species of Takydromus (T. amurensis, T. wolteri, T. tachydromoides oldi, T. kwagakunesis and T. auroralis) reported in Korean Peninsula to date. For this purpose 114 Takydromus specimens were collected from April 2003 to october 2004 in Southern Korean peninsula and morphological characters inclusive of the presence of contact between front-nasal and fostral and the number of femoral pores have been analyzed. The analysis reveals that T. kwagakunesis and T. auroralis should be synonymized to T. amurensis. In addition, the Korean Takydromus consists of two species of T. amurensis and T. wolteri.

  • Herpetofauna biodiversity was surveyed at the Chin-do. The results are as follows: During census periods presence of 2 orders, 4 families, 6 species of amphibians and 1 order, 2 suborders, 4 families, 8 species of reptiles were observed or found indirectly by auditorial recording from residents at the Chin-do. Among them 1 protected wildlife(Agkistrodon saxatilis) and several rare species such as Takydromus wolteri, Sciucella laterale laterale and Zamenis spinalis were indentified. Rana nigromaculata and Rana catesbeiana were found in all surveyed areas. Dominant amphibian species was Rana rugosa (D'= 25.8%) and reptile was Takydromus wolteri (D'= 21.8%). Among 4 areas survey area, Uisin-myon showed the highest level of species richness, diversity, and evenness indices (R'= 2.393, H'= 1.931, and E'= 0.7772, respectively). The species richness of Kunnae-myon was lower (R'= 0.932) than other surveyed regions. Based on the frequency of occurrence (85.71%), habitation density of Rana catesbeiana was very common in Chin-do, suggesting that spreading of this foreign species in the entire Korean peninsula. Scincella laterale laterale, Elaphe dione, Elaphe rufodorsata, Dinodon rufozonatus rufozonatus, Rhabdophis tigrinus tigrinus, Agkistrodon ussuriensis, and Zamenis spinalis showed low frequency of occurrence ( < 10%) and efforts to protect them are required.

  • This study was conducted to find the sexual size dimorphism(SSD) in morphometric characters of three species, Eremias argus, Takydromus amurensis and T. wolteri in lacertid lizard from Korea. Six external traits, snout-vent length, tail length, head length, head width, forelimb length and hind-limb length were focused to compare two sexes among the each three lizards. Student's t-test was used to compare the adult SVL between the sexes for each species. For the other parts of the body, a one-way analysis of covariance(ANCOVA) with SVL as the covariate was used. In all these species, males have longer tail and head than females like general lacertid lizard. In addition, male E. arugus have broader head and longer forelimbs and hind-limbs than conspecific females. Likewise, male T. wolteri have broader head than females. In the three lacertid lizards from Korea, snout-vent length did not significantly differ between the sexes. To understand the causes for SSD in SVL, ecological information, such as the presence/absence of male-male combat and the correlation between the SVL of female and litter size, is required. Therefore, further ecological study on the three species of lacertid lizard from Korea will make it possible to explain the reason SSD is not found in SVL.

  • Although lizards are important hosts for hard ticks (Ixodidae), very few studies have been conducted in South Korea. To determine whether or not hard ticks can infest lizards endemic to South Korea, we examined 77 lizards of four species (Eremias argus, Sincella vandenburghi, Takydromus amurensis, and Takydromus wolteri) that were collected at 22 different sites between April and October 2010. We confirmed that all four lizard species can be infested by Ixodes nipponensis larvae or nymphs. Of the 62 E. argus examined, we found an average of 12.5 larvae on two lizards and an average of one nymph on one lizard. We found seven nymphs on one S. vandenburghi. We found an average of two nymphs on two of the five T. amurensis and an average of one nymph on four of the nine T. wolteri. Ixodes nipponensis larvae and nymphs were found most frequently on the foreleg axillae (87.8%), followed by the forelegs (7.3%), the eyelids (2.4%), and the ears (2.4%) of the lizards. To the best of our knowledge, this is the first report of I. nipponensis infestations of lizards endemic to South Korea.

  • This study was carried out to investigate the herpeto-fauna at Hallasan National Park. We conducted a survey at 1100 Resting places, Eoseungsaengak, Donnaeko, Eorimok, Yeongsil, Gwaneumsa and Seongpanak from April, 2006 to January, 2007. A series of four families and 5 species of amphibians and 4 families and 8 species of reptiles were observed. Amphiesma vibakari ruthveni, Takydromus wolteri, Scincella vandenburghi, Coluber spinalis and Hynobius quelpartensis which are rarely appearing inland but they were frequently observed by this survey. Also, we observed Sibynophis chinensis that only inhabits Jeju island with in Korea. Jeju island has both southern and northern boundary lines for amphibians and reptiles. Amphibians and reptiles in Jeju island have a different from those inland and valuable information for biogeograpy due to dissimilar climate and isolation from continental for a long time. It is not certain whether some amphibians and reptiles, Bufo gargarizans, Rana rugosa, R. plancyi, Elaphe rufodorsata and Takydromus amurensis, inhabit Jeju island, as recorded in previous literatures, so the research on current status of them has to be carried out immediately.
