Numerical analysis based on 33 morphological characters from 25 populations of 8 species of tribe Forsythieae in Korea was conducted to investigate the taxonomic delimitation and discuss the systematic relationships. In this study, Fontanesia phyllyreoides Labill was adopted as comparing outgroup to discuss the taxonomic status of Abeliophyllum distichum and elucidate the taxonomic relationships between tribe Forsythieae and tribe Fontanesiae. Based on the results of PCA, the sum of contributions for the total variance of three major principal components was 79.6% (PC1 54.2%, PC2 15.4% and PC3 10.0%, repectively). Two dimensional plotting from PCA results recognized three distinct generic clusters. Among the populations of Forsythia, two distinct groups were clustered as I. koreana-saxatilis-viridissima and II. ovata-nakaii. However, 15 populations of Abeliophyllum distichum were arranged randomly without any tendency, and the infraspecies of Abeliophyllum distichum could be recognized as individual variations. Fontanesia phyllyreoides Labill was clustered independently and intertribal limitation was clearly distinguished.

한국산 유영류(다모강)의 분류학적 연구의 일환으로 1965년부터 1986년까지 우리나라의 삼면연안과 도서지방(36개 지역)에서 채집된 표본을 동정 분류하였다. 그 결과 10과 20속 31종 2 종이 밝혀졌으며 그 중 4아종 1 아종(Amphinome rostrata, Haplosyllis tentaculata, Typosyllis aciculata orientalis, Typosyllis variegata, Glycera subaenea)은 한국미기록종으로 판명되었다. 눈썹참갯지렁이 (Perinereis nuntina)는 총 36개 지역 중 11개 지역에서 채집되었으며 , 총 600여 개체중 232 개체가 채집됨으로써 우리나라에 널리 분포해있는 종으로 나타났다. 동정 분류된 표본 중 한국과 일본 해역에만 분포하는 것은 3 종이었다.

Numerical analysis based on the 67 morphological characters from 28 populations of 6 species of Korean Rhus sensu lato (Anacardiaceae) was performed for the taxonomic delimitation. Based on the results of PCA with 47 quantitative characters, the sum of contributions for the total variance of three major principal components was 77,9% (PCl 35.2%, PC2 22.5% and PC3 20.2%). The sum of contributions for the total variance of three major principal components were 90,7% (PCl 37.7%, PC2 33.0% and PC3 20.0%) based on the results of PCA with 20 qualitative The characters. Two dimensional plotting from PCA results recognized six distinct species. UPGMA phenogram based on simple matching coefficient method recognized clear taxonomic delimitations among six taxa. On the cluster analysis, qualitative characters were more useful for grouping the species treated. Numerical analysis was very valuable to delimit the Korean taxa of Rhus s.l.

Hada(1936) reported thelist of 14 species of Korean freshwater Rotifer for the first time. Since his report, there have been no taxonomic studies on the Korean except some sporadical reports which contained lists of species as a partial result of limnological study. The author made a list of 145 species of Korean freshwater Rotifera reported until 1988 with reference as convenient compendium for further taxonomic research.

This study evaluates the applicability of the classification rule of hydrological soil group proposed by Lee et al. (2018) with its application to three river basins (Jungmuncheon, Cheonmicheon, and Hancheon) in Jeju Island. The CN values are estimated as results of this application to these three basins, which is then compared with those estimated by applying the conventional three methods. Additionally, previous studies related with the classification of soil groups of Jesu Island, such as the infiltration and rainfall-runoff analysis, are reviewed to evaluate how the resulting hydrological soil groups vary depending on the adopted classification method.. Summarizing the results is as follows. (1) Comparison result of the hydrological soil groups of Jeju Island with respect to the classification method shows that the soil group B is dominant in the application of Lee et al. (2018). However, it is hydrological soil groups C and D in the application of Hu and Jung (1987), hydrological soil groups A and C in the application of Jung et al. (1995), and hydrological soil group D in the application of RDA (2007). (2) In all the applications of Lee et al. (2018) to three selected river basins in Jeju Island, the CN valuse are found to be smaller than those by other conventional three methods.. Lastly, (3) The evaluation results of previous studies related with the classification of hydrological soil groups analysis in Jeju Island shows that the CN value in the Jeju Island may be smaller than those estimated by conventional three methods, also the initial loss higher than 0.2S.

본 연구는 울릉도의 성인봉과 태하령지역의 산림식생을 분류하기 위해 199년 7-8월에 36개소를 선정하여 식생조사를 실시하였으며 식물사회학적 방법과 TWINSPAN에 의하여 군락을 분류하였다 울릉도 산림의 종조성표에 의한 군락 분류결과 너도밤나무-섬노루귀 군락군으로 판명되었다 이 군락군은 다시 솔송나무-섬잣나무 군락, 참나도히초미-졸방제비꽃군락으로 크게 나뉘어졌으며 참나도히초미-졸방제비꽃군락은 다시 전형하위군락. 섬조릿대하위군락 일색고사리하위군락으로구분되었다 TWINSPAN에 의한 분류결과는 솔송나무-섬작나무군락 너도밤나무-섬조릭대군락 너도밤나무-일색고사리군락, 너도밤나무-큰두루미꽃군락으로 구분되었다 식물사회학적 군락 분류결과와 TWINSPAN에 의한 군락분류결과는 4개 군락으로 구분되는 일치성을 보이고 있어 두 방법에 의한 군락 분류방법은 상호 보완될수 있다고 판단된다.

The taxa of Dryopteris subg. Erythrovariae are variable in morphology, resulting in taxonomic confusion in delimiting taxon boundaries. We examined the morphological characteristics of the Korean members of subg. Erythrovariae to clarify their taxonomic identities and relationships. The shapes of the blades, pinnae, and pinnule apices, the shapes and colors of the scales, and the positions of sori were useful for delimiting the Korean taxa of the subgenus. Based on the results of this study and evidence from previous studies, 13 taxa comprising 12 species and one variety of Dryopteris subg. Erythrovariae were recognized in Korea. Descriptions of all Korean taxa of the subg. Erythrovariae and a key to the species are provided. The descriptions presented here are based on field observations and the examination of some 1,000 specimens from the major herbaria of the world.

This study proposes a new method for categorizing the hydrological soil groups by considering the recent revision results of soil series. Also, the proposed method is evaluated by comparing the categorizing result with those based on existing three different methods. As an example, the proposed method is applied to Jeju Island to estimate the CN value, which is then compared with CN values estimated by applying the existing three different methods. Summaries of the results are as follow. (1) The revision result since 2007 shows that the soil texture has been changed in the 43 soil series, the drainage class in the 1 soil series, the permeability in the 15 soil series, and the impermeable layer in the 26 soil series. (2) The categorizing result of hydrological soil groups by applying the proposed method shows that the group B is the most dominant group covering up to 49.25%. On the other hand, one of the existing method of 1987 provides the group C as the most dominant group (46.43%). Method of 1995 defines the group B as the most dominant group (27.69%). The other method of 2007 distinguishes the group D (35.82%) to be the most dominant group. (3) Also, the CN value estimated by applying the proposed method to Jeju Island is found to be smaller than those based on existing three methods. This result indicates the possible overestimation of the CN value when applying the existing three methods.
