Effects of Air Pollution on Precipitation and Living Organisms in Seoul Area(3. Contents of S, Pb and Cd in Litters of Ginko biloba)
Chang, Nam-Kee ; Lee, Kyung-Hyung ;
The Korean Journal of Ecology, volume 13, issue 3, 1990, Pages 165~172
The contents of Pb and Cd in litters of Ginko biloba collected from thirty-four areas in Seoul were measured and analyzed for among relative air pollutions. S contents in litters of G. biloba were 0.88% at Hyehwadong, 0.98% at Yongsan and 0.95% at Ch angdong. Mean value were 0.65% in 0-10 km areas from Kwanghwamun, but were 0.47% in 10-15 km areas. In S contents, the correlation between 0-5 km area and 10-15 km area from Kwanghwamun was high significant, but correlation between 0-5 km area and 5-10 km area from Kwanghwamun had no significance. Pb contents were 118.95 ppm at Pildong, 112.22 ppm at Ulchiro 3-ga and 105.55 ppm at Bus terminal (Banpo). In Pb contents the correlation between 0-5 km area and 10-15 km aea from kwanghwamun was high significant, but the correlation between 0-5 km area and 5-10 km area from Kwanghwamun had no significance. In Cd contents. Cd contents were high in Youido, Shinch on, Kongdokdong, Haengdangdong, Kirum, Ch ongnyangni and Imundong.

The contents of Pb and CD measured with the barks of Pinus densiflora in Seoul area, Yangjaedong area near the Kyungbu-highway, Mt. Keryong and Mt. Seolak area, from Sep. to Ock. in 1988. Pb contents in Seoul area were 17.8 ppm at Changkyungkung, 17.1 ppm at Chongamdong, 13.2 ppm at Mt. Kwanak, 7.6 ppm at Mt. Dobong and 3.7 ppm at Mt. Surak. Except Mt. Kwanak, the difference between areas of central and mountains in Seoul were high significant. Mt Seolak area also showed variations in Pb contents from 16.8 ppm to 32.1 ppm according to studied sites. Cd contents in Seoul area were 0.47 ppm at Changkyungkung, 0.65 ppm at Chongamdong, 0.61 ppm at Mt. Kwanak, 0.52 ppm at Mt. Dobong, 0.47 ppm at Mt. Surak. Therefore, Cd contents in Seoul area exhibited more variations between sampling plots than between the areas of central and mountains in Seoul. Mt Seolak area also showed variations from 0.20 ppm to 0.34 ppm in Cd contents, and it was the lowest in all the studied area.

The Korean Journal of Ecology, volume 13, issue 3, 1990, Pages 181~190
Chodo Archipelago (
13 E and
25 N, ca.
), a part of the Dadohae National Marine Park, largely is covered with substitutional vegetation under various human impact such as grazing, cutting for firewood. However natural vegetation is partially distributed in the tutelary shrine forests, deep valleys and etc. From October 1988 to June 1989, phytosociological investigation of this forest vegetation was carried out by Braun-Blanquet s method. The forest vegetation was classified into 1 association and 7 communities. Ardisio-Castanopsietum sieboldii, Machilus thunbergii, Quercus acuta, Litsea japonca, Eurya japonica-Pinus thunbergii mixed forest, Pinus densiflora, Pinus rigida afforestation. Carpinus coreana community. Based on the classification, the actual vegetation map was drawn in 1 : 50,000 scale.

Chang, Nam-Kee ; Kim, Heui-Baek ; Oh, In-Hye ; Chang, Myung-Ae ;
The Korean Journal of Ecology, volume 13, issue 3, 1990, Pages 191~202
For the maximun yield of the forest trees in the forest management, the growth of annual ring area of the major forest trees was analysed in the four areas in South Korea. The time to the maximum productivity and the optimum cutting time for the maximum yield were estimated. The growth curve of annual ring area showed sigmoid like that of other organisms. Only the growth coefficient among the areas between Fraxinus rhynchophylla and Pinus koraiensis represented significance (5% level). The growth coefficient among forest trees between Pinus densiflora and Abies holophylla, Larix kaempferi and Carpinus laxiflora, Larix kaempferi and Quercus mongolica, Larix kaempferi and Quercus serrata, Larix kaempferi and Pinus koraiensis, and Larix kaempferi and Abies holophylla represented significance (5% level). Among eight forest trees, the time to maximum productivity (tm) of Larix kaempferi was the earliest (21.4 year), and Abies holophylla was the latest (91.9 year). The optimum cutting time for the maximum yield (tc) of L. kaempferi was the earliest (29.4 year) and that of A, holophylla was the latest (122.2 year) of all communities. The optimum cutting time for the maximum yield was 1.33 times as late as the time to the maximum productivity. If the growth of annual ring area as the forest tree for wood is regarded, L. kaempferi and P. densiflora are thought to be more economical than A. holophylla and P. koraiensis.

Kwon, Ki Chung ;
The Korean Journal of Ecology, volume 13, issue 3, 1990, Pages 203~214
The work reported here aims to assess how Knots, Calidris canutus, accumulate rapidly large energy and nutrient reserve at Red Car in England. Most of Knots in England belong to long billed, long winged population compare with subspecies in Korea. The rate of prey intake of Knot increases as a nearest neighbour distance decreases. Foraging rate and vigilance rate increases as flock size decreases. The calorific value of each sized of Common Mussel Mytilus edulis, main food species of Knot, are almost same each other but the calorific content of each size Mussels are quite different each other. The rate of daily energy intake of Knots have been estimated from 192 kcal to 270 kcal.

The Korean Journal of Ecology, volume 13, issue 3, 1990, Pages 215~224
The distribution of Spirodela polyrhiza and Lemna aequinoctialis was investigated and the limiting factors on the distribution were analyzed. At 66 sites in Korea, the presense or absense of duckweed were recorded and the water was sampled. The temperature, hardness, pH and contents of N, , , Na, K, Ca, Cu, Mg, Zn, Fe, Ni, Mn and Cd of water sampled were analyzed. The results were as follows; It seemed that the limiting factors influencing on the distribution was water temperature and concentration of . The critical temperature of the distribution of Spirodela and Lemna was presented 19.5
and concentration of was limiting factor only in the distribution of S. polyrhiza. L. aequinoctialis was distributed in lower temperature than S. polyrhiza and it seemed that the distribution of L. aequinoctialis was not be influenced by the concentration of .

The Korean Journal of Ecology, volume 13, issue 3, 1990, Pages 225~236
We studied that seeds of wild radish with different size of weight can be obtained for the purpose of differentiation and growth of these seeds by total growth periods. This study is practised a view of plant eco-physiological side and dry-matter production. Through whole growth periods, we knowthat seed weight of L plots was higher than that of M and S plots. In the 33th day after day after germination, growth values of L, M and S plots were 13.93, 7.77, and 4.61 g/plant, respectively. Growth of shoot (cotyledon and leaf) area and shoot weight were shown the similar trends with individual plant dry-amtter weight. In the 33th day after germination, shoot area of L, M and S plots were 21.55, 11.81 and 8.75
/plant and shoot dry weight of L, M and S plots were 10.83, 6.03, 3.50 g/plant, respectively. In the early stage of growth (the 10-14th day after germination), the values of RGR of seed weight of L, M, S plots were 0.2887, 0.2807 and 0.2365 g/g/day, in the late stage of growth, those values of RGR of L, M, S plote were 0.2721, 0.1716, 0.1727 g/g/day, respectively. In the early stage of growth (the 14th day after germination), the values of NAR or L, M and S plots were 0.1513, 0.1373, and 0.1094 g/
/day, respectively. It is thought that seed weights were influenced seriously effect in the early stage of growth. The NAR value, in the late stage of growth (the-28-33th day after germination), of L, M and S plots were not large different as 0.1086, 0.1097 and 0.112 g/
/day, respectively. The LAR values of M and S (2.0396, 2.1520
/g) plots, in the early stage of growth, were higher than L (1.9037
/g) plots. In the late stage of growth, the value of LAR of L plots were nearly same as M plots, but the value of S plots were higher than that of L and M plots (0.0458
/g). And, in the early stage of growth, the values of SLA of L, M and S plots were 2.2123, 2.2107 and 2.8448
/g, respectively. We measured the photosynthetic rates and the respiratory rates as the physiological characteristics of wild radish. In the early stage of growth, the photosynthetic rates of L, M and S plots were 12.4, 14.4, 9.8
/sec and 9.4, 11.4, 9.8
/sec in the late stage of growth, respectively. In this result, it could be informed that photosynthetic rates in the late stage of growth were lower than the early stage. In the middle stage of growth, the respiratory rates were 0.793,
/min in shoot, and 3.28
/min in root without relation to seed weight. The growth analysis of plants was used by Hunt & Parson s computer program (1974, 1981) and its results used this program were good. Therefore, in this sense, it could be expected that the computer program used and developed largely in researches of plant growth.

Ninety six plant species recorded at the alpine tundra zone on the Paektusan (Zhu and Rowe, 1987) were examined on the floras of alpine and subalpine zones in Korea. Among the 96 species, 59(61%), 47(49%) and 51(53%) species in the alpine zone of Kwanmobong, Turyusan and Puksubaeksan were recognized respectively, and 24(25%), 21(22%), 11(11%) and 16(17%) species in the subalpine zone of Myohyangsan, Kumgangsan, Soraksan, Chirisan and Hallasan respectively. The similarities between the alpine tundra zone of Paektusan and the alpine zones of other mountains in Korea showed high values than the values compared with subalpine zones.
