한국산 뱀아목(Serpentes)의 허물을 이용한 종식별 연구 = A Study on Species Identification Using shed Snake Skin of Korean Snake (Serpentes)

다국어 초록 (Multilingual Abstract)

The purpose of this study was to derive a method for identifying at the species level using the shed skins of 11 species of Korean snake suborder from 2020 to 2023. Unique characteristics were defined by cross-comparing the images of carcasses (roadkill and natural death) collected at the site and captured individuals with the skins.
Various structural characteristics, such as the scale structure of the top of the head, the number of preoculars, the number of post-oculars, loreal scales, temporal scales, ventral scales, and anal plate structure were analyzed and organized by species. Compared with the dorsal pattern, the situation in which the number of ventral scales changes due to the "gap scale" was identified by type, and presented as a diagram to enable visual comparison.
Nine upper head scales (internasal 2, prefrontal 2, frontal 1 Parietal 2, supraocular 2) were identified as unchanging traits in 11 species of snake subspecies, but they could be applied as follows as an important feature of species identification in terms of various structural differences, sizes, and numbers of lateral scales. In The temporal plates showed that of the seven snakes, one in the first row of two lateral plates, Rhabdophis tigrinus and Ampiesma vibakari, differed in the number of various dorsal scales on the dorsal surface, and the role of interval scales was identified as the main cause of changes in dorsal central scales.
The location of the niche scale was found to be high as dorsal as it went to a species with a large number of equal scale columns. In anal plates, among the seven species of snake family, the anal plates of one species of Dinodon rufozonatum were not divided, which was the same as those of three species of Viperidae.
By establishing and applying the filtering process based on the results derived from these results, it was confirmed that it was possible to identify of 11 Korean snake subspecies using shed skins.
The identification process of the developed filtering format is a non -invasive method that increases accuracy through each step, and each fect could be used to identify snake species in the field only by enlarging images taken with mobile phones and digital cameras and using Lupe. It enables accurate identification based on the unique number and arrangement of scales depending on the species, and is a practical method that can be applied in various environments. In particular, species can be accurately identified only by their fect without directly capturing snakes in ecological surveys or conservation activities, which can greatly improve the efficiency of field work. It can provide important data for the study of the ecology and behavior of snakes and can contribute to the establishment of conservation management strategies.
