| 2 | Report of a Dicephalic Steppes Ratsnake (Elaphe dione) Collected in South Korea显示文摘In this report,we describe morphological characteristics of a dicephalic Steppes Ratsnake(Elaphe dione) collected from the wild in 2011 in South Korea.The specimen has two heads and two long necks.Unlike normal individuals,the dicephalic snake has divided ventral scales under the necks of the bifurcated columns.The snoutvent length(SVL) and overall total length of the individual are shorter than those of normal snakes of the same age.Nevertheless,the counts of nine different scale types that are often used for classifi cation are all within the ranges of normal individuals.As far as we know,this is the f irst detailed morphological description of a dicephalic E.dione in the scientif ic literature. | Il-Hun KIM Ja-Kyeong KIM Jonathan J.FONG Daesik PARK | 2013 | Asian Herpetological Research2013，4，3： | 0 |
| 3 | Can an Invasive Prey Species Induce Morphological and Behavioral Changes in an Endemic Predator? Evidence from a South Korean Snake(Oocatochus rufodorsatus)显示文摘Introduction of an invasive prey species into an ecosystem may affect an endemic predator's fitness by altering the prey-predator system. Successful adaptation may allow the endemic predator to eat and control the invasive species, while unsuccessful adaptation may result in extinction of the predator. We examine the possible effects of the invasive North American bullfrog(Rana [Lithobates] catesbeiana) on the endemic Red-backed rat snake(Oocatochus rufodorsatus) in South Korea. We do so by comparing the morphology and behavior of adult and hatchling snakes from bullfrog-exposed(Taean) and bullfrog-unexposed(Hongcheon) populations. Among the seven morphological characteristics investigated, relative tail length(tail length/snout-vent length) of both adults and hatchlings from Taean was significantly greater than that of adults and hatchlings from Hongcheon. Also, adult snakes from Taean had a significantly shorter latency of first tongue flick in response to prey compared to adults from Hongcheon. This difference was not observed in hatchlings. In other snake species, a longer relative tail length and shorter latency of first tongue flick are known to improve foraging efficiency, and these characters may be adaptations of O. rufodorsatus to prey on bullfrogs. This study provides preliminary evidence that the presence of an invasive prey species may cause morphological and behavioral changes in an endemic predator. | Jun-Haeng HEO Heon-Joo LEE Il-Hun KIM Jonathan J.FONG Ja-Kyeong KIM Sumin JEONG Daesik PARK | 2014 | Asian Herpetological Research2014，5，4： | 0 |
