본 연구에서는 희귀수종인 가침박달의 외부형태학적 형질을 재검토하여 기존 문헌 및 선행 연구와의 차이를 파악하 였으며, 식물상 문헌 및 표본정보를 통해 국내 분포도를 작성하였다. 또한 토양의 이화학적 특성을 분석하여 외부형태형 질과 토양 조건과의 상관성을 고찰하였다. 가침박달 자생지 토양분석 결과, 유기물함량 3.25-29.83%, 전질소함량 0.15-1.14%, 유효인산 3.0-156㎎/㎏, 치환성 K+ 0.39-1.49cmol+/㎏, 치환성 Ca2+ 2.48-38.07cmol+/㎏, 치환성 Mg2+ 0.77-18.29cmol+/㎏, 양이온치환용량 7.3-23.0cmol+/㎏으로 확인되었으며, 토양 pH는 4.6-7.1인 것으로 조사되었다. 대구 앞산 집단의 경우, 유기물함량, 전질소, 양이온치환용량이 가장 높았고, 화서의 길이가 길고, 꽃의 수가 많아 다른 지역에 비해 유의성 있게 차이를 나타냈다(P < 0.001). 또한, 집단의 유전적거리와 지리적 거리, 일부 외부형태형 질의 차이를 통해 이들의 상관성을 확인할 수 있었다. 희귀 수종인 가침박달의 생육특성을 파악하고, 서식지 내 보존을 위해 외부형태형질, 유전적 구조, 생육상태, 식생구조, 환경특성 등 다양한 데이터의 종합적 고찰이 필요하다.

This study was conducted to screen the characteristics of external and cranial characters of Crocidura shantungensis collected from Korean Peninsula, Ulleung Island and Jeju Island. There were significant differences in head-body length (HBL), tail length (TL), ear length (EL), and hind foot length (HFL) in males and HBL, TL, and HFL in females among three populations (p<0.05). The HBL and TL in the Jeju Island population were larger (8.0 mm and 4.0 mm in lengths, respectively) than those of the Korean Peninsula population. Based on skull analysis, a total of thirteen traits showed significant differences among the three populations (p<0.05). The condylo-insicive length (CIL), maximum width of brain case (MWB), mandibular length (ML), and mandibular height (MH) in the Jeju Island population were significantly larger than those of Korean Peninsula population (p<0.05). Principle component analysis (PCA) showed that two principle components (PC) identified from the PCA affected on the body size and width of the skull, respectively. Discriminant analysis revealed that these populations could be discriminated through skull traits. These findings concluded that the Jeju Island population was greater in the size than the Korean Peninsula, suggesting that the Jeju Island shrews have successfully adapted to the island environments and they had morphologically differentiated during glacial period after natural immigration into that Island. Thus, this study supports the ‘Island Rule’, showing that the population is well adapted to the island environments. This may provide important information for biogeographical and ecological studies on insular animals.

We have analyzed the external morphology and the environment of the foraging site of Vespertilio sinensis. The external morphology was analyzed by twelve parameters and the environment characteristics of the foraging site was analyzed using GIS 10.1 program. The wing membrane was inserted into the ankle of the hind foot and the wing ratio was 1.42, the middle type between broad-short wing type and long-narrow wing type. The fur color was blackish brown but the guard hair color was whitish. The shape of the ear was a rounded triangle and tragus was a fan shape. This study showed that V. sinensis preferred the deciduous forest of the upper forest zone, where human interference was less. We believed that abundance of insects, depending on water system, was closely related to the use of the foraging site. This result showed that the environment characteristics was very similar to the nature preservation zone including Baekyang valley and Keumsun valley in Naejangsan National Park.

The Ussurian tube-nosed bat (Murina ussuriensis) is a registered endangered species that has not been observed in South Korea since 1960. We were able to capture three individuals of M. ussuriensis between 2011 and 2013 at Sobaeksan National Park. The discovery of this species was the first time within 50 years. To collect basic data on the M. ussuriensis, we analyzed the external morphology and ultrasound characteristics of the captured bats. The results indicated that M. ussuriensis weigh approximately 5.2 g, which is less than that of a typical small bat such as Pipistrellus abramus. The bat's wing-type ratio was determined to be 1.22 and classified as a broad and short wingspan type. The bat uses FM signals for ultrasound with a peak frequency of 92 kHz. The M. ussuriensis seems to be a forest-dwelling bat that preys on insects by maneuvering expertly within the complex mazelike structure of forests. In the future, further research on the hibernation and foraging sites of the bats is necessary to protect and monitor the species.
