Morphometric Analyses on 24 Species (13 Families of Six Orders) of Korean Mammals

한국산 포유동물 24종(13과 6목)의 형태적 형질의 분석

Four external and 22 cranial characters of 279 specimens representing 24 species of six orders of Korean mammals were measured. The data were analyzed by phenetic methods such as ordination as well as clustering techniques. Morphological distances were also calculated. Phenetic studies yield taxonomic placements of Siberian mink, Palearetic squirrel, and big white-toothed shrew which are incorrect. Morphological differences among Korean mammals at ordinal level in the taxonomic hierarchy are larger than those among other mammals: morphological differences below ordinal level are comparable to those among other mammals. Average taxonomic distances and morphological differences among Korean mammals at various levels in the taxonomic hierarchy are jointly monotonic, although the value of Pearson's product-moment correlation coefficient between average taxonomic distance matrix and morphological difference marrix is 0.59.

한국산 포유동물 6목 24종 279표본의 4개 외부형질과 22개 두골형질들을 측정하였으며, 측정치를 ordination법과 clustering법에 의해서 분석하였다. 형태적 분석의 결과는 족제비, 청서 및 토마스 땃쥐가 현존 분류체계상의 위치와 다르게 나타났다. 한국산 포유동물의 목 수준에서의 mrophological difference는 다른 포유동물보다는 크게 나타났으나, 목 이하의 수준에서는 별 차이가 없었다. 분류학적 체계에서의 단계가 높아질 수록 average taxonomic distance morphological difference의 수치는 커졌으며, 두 행렬식간의 상관계수는 0.59였다.
