  • 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.

  • The distribution and the frequency of endocrine cells in the GIT of the Amur lizard(Takydromus amurensis) were investigated using silver techniques and immunohistochemical method. Only argyrophil cells stained by the Grimelius technique were found numerous in the pyloric glands and moderate in the duodenum. Two types of immunoreactive endocrine cells were identified by immunohistochemical method. Bovine CG-immunoreactive cells were demonstrated the entire GIT. BPP-immunoreactive cells were restricted in the duodenum and the ileum. The results showed that: the number of argyrophil cells was lower than the number of cells stained with bovine CG antiserum. Therefore, bovine CG-immunostaining and the Grimelius silver technique did not correspond with various endocrine cells in the Amur lizard.

  • 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.

  • 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.

  • Amphibian and Reptilian specimens which were surveyed in Gyebangsan during both from Apr. 26, 1995 to Oct. 15, 1995 and from Apr. 13, 1996 to July 28, 1996 were observed 9 Species in 5 Families on 2 Orders and 10 Species in 3 Families, 5 Fimilies, 9 Species and Reptiles were 2 Suborders, 3 Families on 2 Suborders, respectively. Bombina orientalis was revealed dominant species and Bufo stejnegeri was distributed abundant on this investigation area than other survey studies. Relatively large number of larvae of Rana dybowskii were found among the stream and small ponds at the Suchung-gol valley. There were 5 species of Specific wildlife species in Korea as Hynobius leechii, Rana dybowskii, Onchodactylus fischeri, Bufo stejnegeri and Bufo bufo gargarizans. Meanwhile Bufo stejnegeri were endemic species in Korea. 6 Species among 10 Species which were observed Reptiles in this survey Scincella laterale laterale, Dinodon rufozonatus rufozonatus, Agkistrodon brevicaudus, Agkistrodon saxatilis, Amphiesma vibakari ruthveni and Enhydris rufodorsata were Specific wildlife in Korea. Scincella laterale laterale and Takydromus amuriensis were habitated very abundant in Suchung-gol region. Habitat density of Takydromus amureinsis at Suchung-gol region was 36 individuals/ha. Total number of pressed to death individuals caused by press on the road from May to July, 1995 were 404 specimens in 10 Species. The 1,2,3 and 4 Stations where were found the largest number of death individuals caused by press on the road should considered to construct Eco-corridor to reduced the death individuals with small pipes beneath the road as a migration route. Onchodactylus fischeri have around 500m as moving distance and home range for lifelong and it were the climax of broad-leaved tree and highly moisture area that abundantly region of Onchodactylus fischeri.

  • This study was conducted to clarify the characteristics of amphibian and reptile (herpetofauna) populations in a coniferous plantation and a deciduous forest from July to September 2013 in national forest, Hongcheon, Gangwon province, Korea. Coverage of understory, mid-story and overstory were more developed in a deciduous forest. We used line transect sampling method on a total of 4 transect lines, 2 lines in each forest type. Fifty two individuals of 4 amphibian species and 11 individuals of 3 reptile species were recorded. Mean observed number of herpetofauna species, individuals and species diversity index (H') were not significantly different between coniferous plantation and deciduous forest. This result related to ecological characteristics of herpetofauna. Habitats of herpetofauna were influenced on not only vertical structure of forests, but also climatic variables, thermoregulation and prey availability. The long-term monitoring and research on habitat preference and seasonal ecological traits of herpetofauna would be needed for conservation and management of herpetofauna in forest areas.
