  • Altitudinal patterns of plant species richness and the effects of area, the mid-domain effect, climatic variables, net primary productivity and latitude on observed richness patterns along the ridge of the Baekdudaegan Mountains, South Korea were studied. Data were collected from 1,100 plots along a 200 to 1,900 m altitudinal gradient on the ridge. A total of 802 plant species from 97 families and 342 genera were recorded. Common and rare species accounted for 91% and 9%, respectively, of the total plant species. The altitudinal patterns of species richness for total, common and rare plants showed distinctly hump-shaped patterns, although the absolute altitudes of the richness peaks varied somewhat among plant groups. The mid-domain effect was the most powerful explanatory variable for total and common species richness, whereas climatic variables were better predictors for rare plant richness. No effect of latitude on species richness was observed. Our study suggests that the mid-domain effect is a better predictor for wide-ranging species such as common species, whereas climatic variables are more important factors for range-restricted species such as rare species. The mechanisms underlying these richness patterns may reflect fundamental differences in the biology and ecology of different plant groups.

  • Distributional pattern of vascular plant species in terms of species-area relationship and distances from their species pool on the 53 islands selected in the South Korea were studied. From the relationship between vascular plant species and area the equation of species-area was established as the follow: S=cA2 c=135.52 z=0.226 S; number of species A; area of island In the equation the Z value 0.226 is lower than those of any other localities reported in the world. Z value increased with the increasing distance from the species pool while C value decreased. The relationships of Z and/or C and distance from species pool, D, were established; Z=0.002D+0.176 C=-39.5logD+178.5 The tendency of common species decrease of them with the increasing islands was fifted to the Fisher's logarithm series. Common species 50% above was 39 species, including the most common species, Pinus thunbergii. Quotient of Similarity value by Sorensen (1948) on common species was relatively low i.e. 0.27∼0.47. It is noticeable for their vegetation conditions that the naturalized plant as a indicator of disturbance, for example Erigeron canadensis, was widely distributed.

  • The purpose of this study is to examine distribution and abundance of wintering raptors in Korea during 2000-2007 which is a rare data set for covering large landscape areas. Total 6,643 raptors of 16 species were recorded at 94 different points in west, south and east coasts, and rivers of inland areas all over Korea. During the study period, the most abundant raptors were black vulture (Aegypius monachus, 62.3%), common kestrel (Falco tinnunculus, 11.0%) and common buzzard (Buteo buteo, 10.0%), and these 3 birds were dominant species in inland areas and also considered as resident species except for black vulture. Also, there was a difference among 5 different habitat types. Black vultures were most found in estuaries whereas common buzzard and common kestrel could be found in coastal areas. Presumably raptors prefer reservoirs and estuaries probably due to lower human disturbance in these areas, and management efforts should be concentrated in inland areas for black vulture and coastal areas for common kestrel and common buzzard.

  • 본 연구는 비인만의 갯벌과 조하대에 서식하는 대형저서동물의 공간분포가 퇴적물의 특성을 반영하는 지를 알아보기 위해 종 조성을 이용한 군집분석을 실시한 후 각기 다른 군집의 퇴적환경의 특성을 비교했다. 대형저서동물은 먼저 조위에 의해 4개의 군집으로 대별되었으며 그 가운데 3개의 군집은 퇴적환경의 특성에 따라 세부군집으로 나뉘어졌다. 모든 군집에서 공통으로 출현하는 종인 Nephtys californiensis Hartman 1938, Haploscoloplos elongatus Johnson 1901, Glycera sp., Heteromastus sp. Notomastus sp. Timarete amtarctica Monro 1930, Glysinde sp., Lumbrineris japonica Marenzeller 1879 에 대한 서식밀도의 높낮이는 서식지의 퇴적환경이 서로 다르기 때문인 것으로 나타났다. 그러나 공통종 가운데 2종만이 일부 퇴적환경과 통계적으로 유의한 상관성이 있는 것으로 나타났다. 공통종의 시간에 따른 밀도변화는 4계절 조사로는 해석하기 힘들었으며 생활사의 변화를 알아내기 위해서는 좀 더 빈번한 조사가 필요했다.

Twenty species including Cuculus canorus were summer migrants, and 30 species including Platalea leucorodia were winter migrants. Seventeen species including Limosa limosa were occasionally species. And Rostratula benghalensis was an unconfirmed species. Species diversity index (H') was 0.72; species equally common index (e/sup H'/) was 2.06. In January, maximum observed 102,121 individuals. However in July 52 species were observed most variously. There were total 81,152 birds observed with 11 orders, 22 families, and 71 species at the B area. Fifteen species including Falco tinnumculus were resident species. Summer migrants were 18 species including Ixobychus sinensis. Winter migrants were 25 species including Ciconia boyciana. Thirteen species including Tringa glareola were occasionally species. Species diversity index (H') was 0.281; species equally common index (e/sup H'/) was 1.325. In January, maximum observed 78,433 individuals. However in Silly 42 species were observed most variously.

  • The potential cultivation of buckwheat species in Luang Prabang region, Lao PDR where the species has not been naturally grown and not traditionally utilized was studied to introduce buckwheat as a new agricultural material, especially for food and medicine. The growth of Tartary buckwheat species was higher than common buckwheat showing 2.3 fold of plant height compared to common buckwheat. Number of flower per plant in Tartary buckwheat (731) was three fold higher than common buckwheat (244). Dry weight per plant was respectively 1.7 g in Suwon No. 1, 2.6 g in Suwon No. 2, and 1.4 g in KW45. The rate average of seed setting was similar between common buckwheat (41 to 46 %) and Tartary buckwheat (44%). Total seed yield of Tartary buckwheat (184 kg/10 a) in 10a could be estimated to be higher than that of common buckwheat (108 kg/10 a).

  • Hibiscus속 (아욱과)의 27개 종에 대한 안토시아닌분포를 조사한 결과 절(section)간 안토시아닌조성의 차이를 관찰하였다. 가장 대표적으로 발견되는 안토시아닌은 delphinidin과 cyanidin의 3-xylosyglucoside와 3-glucoside로, Trichospermum, Fucaria, Trionum, Abelmoschus, Ketmia절에 속하는 종들에서 나타났다. Cyanidin 3-sophoroside는 Lilibiscus절의 종들에서 발견되는 대표적인 안토시아닌이었다. Bombycella절에서는 6가지의 common anthocyanidin의 3-glucoside와 3-malonylglucoside가 검출되었다. 이러한 안토시아닌의 절간 분포 차이는 기존의 형태적 자료에 기초를 둔 section의 구분 범주와 잘 일치하였다. 또한 자가불화합성을 나타내는 section에서 다양한 안토시아닌의 변이를 나타내었다. 이러한 안토시아닌의 변이결과들을 수분생태학과 관련지어 논의하였다.

  • This study was carried out to propose the new procedure to apply Habitat Evaluation Procedure(HEP) of target species using delphi technique, which is suitable to develop endangered species with few researches and ecological knowledges. To identify habitat quality of specific species in development project site, we can develop habitat model and create habitat suitability maps. In this study, we select the Common Kestrel(Falco tinnunculus) as target species in four areas(Paju, Siheung, Ansan, Hwaseong) which is located near the Seoul metropolitan area. The Delphi technique was selected to get the reliable information on the species and habitats requirements. Through the delphi approach, seven habitat components were determined as suitable variables for the Common Kestrel: density($n/km^2$) of small mammals, area($km^2$) of bare-grounds, pasturelands and riparian, and open area(%), spatial distribution and area of croplands, landscape diversity, breeding sites(tall trees, cliffs, high-rise buildings), and the length of shelf. Habitat variables used in this model were classified into two categories: % of suitable land-cover type(open areas, croplands, pasturelands, wetlands, and baregrounds) and the quality of feeding sites(within 250m from edges of woodlands). Habitat quality of the Common Kestrel was assessed against occurred sites derived from the nationwide survey. Predicted habitat suitability map were closely related to the observed sites of the endangered avian species in the study areas. With the habitat suitability map of the Common Kestrel, we assess the environmental impacts with habitat loss after development project in environmental impact assessment.
