The Korean Journal of Ecology, volume 23, issue 3, 2000, Pages 193~199
The research about distributional characteristics of coastal mantle communities in South Korea was accomplished. This study was carried out by direct analysis of the latitude and temperatures of each releve site on the basis of syntaxonomy and hierarchical system of coastal mantle communities which was already obtained from Zurich-Montpellier School's method. The distribution of coastal mantle communities in South Korea appeared from North to South in the order of Rosa rugosa community, Vitex rotundifolia community, the Linario-Viticetum rotundifoliae, the Roso-Viticetum rotundifoliae and the Imperato-Viticetum rotundifoliae, and it was recognized that tendencies of continuous and overlapped distribution pattern in adjacent syntaxa. Consequently, It is suggested that the syntaxonomical, geographical and bioclimatic informations of Japan, North Korea and China are essential to determine the distributional patterns of coastal mantle communities in Korean Peninsula.

The flora, distribution area, vegetation structure, annual net primary production, and nutrient uptake of the vascular hydrophytes, hygrophytes and mesophytes were investigated in the wetlands of the Asan-Lake, Chungchongnam-do and Kyonggi-do, Korea from March to October in 1997 to reveal the correlation between the plant community and the lake environment. The flora was composed of 38 families, 89 genera, 106 species, 14 varieties or total 120 kinds of the vascular plants. The life from of the hydrophytes were classified as 14 kinds of emergent plants, 5 kinds of submerged plants, and 4 kinds of free-floating plants, respectively. The number of species was various to 4 ∼85 kinds in each site. The dominant species was Zizania latifolia, and the importance values of Zizania latifolia, Typha orientalis, Phragmites communis, and Spirodela polyrhiza were 39.58, 14.90, 13.97, and 7.64, respectively. The distribution area of the emergent hydrophytes, hygrophytes, and mesophytes was 49.3 ㏊ (90.5%), and free-floating plants was 5.2 ㏊ (9.5%), whereas the floating-leaved and submersed plants were rare. Annual net production of the emergent hydrophytes, hygrophytes, and mesophytes was 547.9 ton D.W./yr (98%), and those of the free-floating plants was 10.5 ton D.W./yr (2%), and 558.4 ton D.W./yr in the whole lake ecosystem. The total uptake of nitrogen and phosphorus by the vascular plants was 7,099 and 1,891 ㎏/yr in the whole lake ecosystem.

We have collected two species of firefly, Hotaria papariensis and Hotaria unmunsana to investigate their patterns of appearances and distributions from May to July in 1999 at 18 localities in Korea. A total of 1,096 individuals of these two species were collected: H. papariensis 584 and H unmunsana 512. The highest appearance level of adult firefly was different from each altitude. They appeared from the beginning of June to the end of June at 200 m sea level, the middle of June to the end of June at 200∼400 m, the end of June to the beginning of July at 400∼600 m and the beginning of July to the middle of July at 600∼800 m, respectively, All regions of these two species were cohabit, but Cheju-do region is the exceptional case. H papariensis was dominant at the northern parts and H unmunsana was the southern parts of Korean peninsula.

The Korean Journal of Ecology, volume 23, issue 3, 2000, Pages 223~229
To develop the restoration technique from urban planted forest to natural forest, sprout growth and its effects on vegetation composition in the early stage after lumbering, were studied, using only Populus albaglandulosa of the tree layer in Chungdam Park Chungdam-dong, Kangnam-gu, Seoul during the two years from 1997 to 1998. The results were as follow. After lumbering, the more basal areas of the parent stump, the more sprouts were generated. The basal area of parent stump was related more to biomass than to the number of sprouts. In the cutting area, biomasses of sprouts were 552.7 g?DW/㎡ in first year and 8.7 g?DW/㎡ in second year after lumbering. Therefore, cutting of sprouts in first year resulted in decrease of sprout production in second year. In the non-cutting area, biomass of sprouts was 657.4 g?DW/㎡ and more than that of the experiment. Especially, 2-year sprouts grew to a 304 cm height by the end of the growing season in the second year. The growing season of sprouts was from early April to early September and almost all the leaves of the sprouts remained at the end of the growing season. Specific leaf area decreased along with time elapse and plant height but the differences were not conspicuous. Therefore, it is thought that the reason why p. albaglandulosa sprouts grew fast was due to a long growing period and lower layer leaves which remained at the end of the growing season. In the cutting area of the P. albaglandulosa sprouts, there were no changes in the number of species in the shrub layer but an conspicuous increase in the herb layer. Coverage was no changes in the shrub layer but an increase in the herb layer. In the non-cutting area of P albaglandulosa sprouts, the number of species and the coverage changed a little, and the main species of the herb layer were Phytolacca americana, Eupatorium rugosum and Panicum dichotomiflorum, which are tall plant species.

The degree to which microenvironmental factors are linked to spatial patterns of vegetational factors within ecosystems has important consequences for our understanding of how ecosytems are structured and for conservation of rare species in ecosystems. We studied this relationships between the spatial patterns of microenvironmental factors and vegetational factors in temperate hardwood forest in Mt. Jumbong Biological Reserve Area, Korea. To do this, environmental and vegetational factors from 196 micropoints in a 0.49 ha plot were investigated. Most of all environmental factors and vegetational factors showed the variations among micropoints. Microtopographic factors, litter depth, soil moisture content and relative light intensity at this site were spatially dependent at a scale of 14∼62 m. Coverage of tree and shrub layer and species diversity of herb layer in autumn were spatially dependent at a scale of < 15 m. Species richness and species diversity of herb layer in spring and species richness of herb layer in autumn were spatially dependent at a scale of 28∼48 m. Multiple regression analysis showed that spatial patterns of species richness and species diversity of herb layer in spring and autumn were affected by litter depth, slope, subtree layer, shrub, Sasa borealis etc. The best predictor for the spatial patterns of species richness and species diversity of herb layer at this site was the spatial pattern of litter depth. Species richness and species diversity of herb layer showed strongly negative correlation with litter depth. We estimate that the spatial pattern of litter depth at this site were affected by direction of wind, microtopography and spatial pattern of shrub layer.

The objective of this study was to examine the effects of microenvironmental heterogeneity on the spatial distribution of herbaceous species in a temperate hardwood forest in Mt, Jumbong which lies within the core area of Mt, Sorak Biosphere Reserve, Korea. Most of all herbaceous species showed the variations among micropoints in a permanant plot. Corydalis turtschaninovii, Disporum smilacinum and Viola rossii in early spring and Meehania urticifolia, Melica onoei and Adenophora grandiflora in autumn showed a high degree of spatial dependence. Anemone koraiensis and Erythronium japonicum in early spring were spatialy dependent at a scale of 50∼54 m. Adenophora grandiflora and Melica onoei in autumn were spatialy dependent at a scale of 8∼20 m. The other herbaceous species were spatialy dependent at a scale of 〉 62m. Coverage of Viola rossii, Disporum smilacinum and Erythronium japonicum were negatively correlated and coverage of Symplocarpus nipponnicus and Corydalis turtschaninovii in early spring were positively correlated with coverage of shrub species, litter depth, soil moisture content, organic matter and soil nutrient contents. Coverage of Isodon excisus in autumn was positively correlated with relative light intensity, litter depth, soil moisture content and soil nutrient contents. Coverage of Ainsliarea acerifolia, Carex siderosticta, Pseudostellaria heterophylla, Aster scaber, Melica onoei and Adenophora grandiflora in autumn were negatively correlated with litter depth, soil moisture content and soil nutrient contents. Leaf litter of forest floor in this hardwood forest was spatialy redistributed by wind direction, shoot density of shrub species and microtopography. Soil moisture content, organic matter content and soil nutrient contents on microhabitat were affected by spatial pattern of leaf litter. In conclusion, we estimate that spatial distribution of herbaceous species in this hardwood forest was largely affected by microenvironmental heterogeneity caused by redistribution of leaf litter.

This study was conducted to clarify the characteristics of bird community in Han River area from Oct. 1997 to Jul. 1998. Total 107 bird species were recorded in Han River area. Bird mainly distributed around Kangdong Bridge, Paldang Dam, Yangsuri, Haengju Bridge, Sungsan Bridge, and Bam island. The area between Dongiak Bridge and Youngdong Bridge showed the lowest the density of birds. The dominant birds of Han River area were the dabbling ducks, which were Anas platyrhynchos and A. poecilorhyncha. Diving ducks were distributed in the Dongiak Bridge, Youngdong Bridge, and estuary area. Grebes, Gulls, Herons, and Coots were also dominant bird species. Cormorants, Swans, Sandpipers, and Plovers were minor birds in Han River area. Maintenance and management of various micro-habitats are needed for habitation of bird community in Han River area.

The objectives of this study were to classify quantitatively vegetational types of P. densiflora for. erecta forest. The results were summarized as follows. 1) According to the canonical correspondence analysis(CCA), variables such as topography, altitude, available P/sub 2/O/sub 5/, and Mg/sup 2＋/were highly correlated on three axes. Based on the correlations between vegetation units and environmental factors, Rhododendron micranthum community tended to be more distributed in the such situations of high altitude, upper topography, high C/N ratio, low level of Mg/sup 2＋/and Ca/sup 2＋/. Vaccinium koreanum community tended to be more distributed in the such conditions of high altitude, upper topography, high level of Ca/sup 2＋/and Ma/sup 2＋/. 2) According to the results of importance value analysis, Tree layer and Subtree layer in study areas showed high Ⅳ along with P. densiflora for. erecta, Quercus mongonlica, Q. variabilis, Q. serrata, Fraxinus rhychophylla and shrub layer indicated that Ⅳ of P. densiflora for, erecta in Sokwang-ri area was higher than those of the other areas. Therefore, it was considered that P. densiflora for. erecta forest of Sokwang-ri area could be naturally regenerated. 3) According to results of species diversity, the species diversity of Uljin region showed the least low value as 0.6622, other regions appeared about 0.7. In the diversity by vegetation types, Acer pseudosieboldianum community showed high value. 4) According to the analysis of community similarity, Sokwang-Ri region was lowly correlated with Uljin region, while the index among the other areas appeared above 0.6. 5) According to the analysis of interspecific association, it was divided into 2 groups. The species of first group were mainly involved in character species, and the species of second group were involved in differential species groups.
