Structure of grassland communities was investigated, and performance of populations of Themeda triandra var. japonica and Miscanthus sinensis were compared on limestone and granite soils. Forty three and forty taxa occurred on the limestone and granite grasslands, respectively, but their similarity was very low. Shoot height and number of hills per patch, as a measure of performance, of Themeda on the limestone grassland were higherthan those on the granite grassland. In contrast, shoot height and number on hills per patch of Miscanthus were higher on limestone than granite grassland. Evidence shows that poor growth of Micanthus population on the limestone soil was associated with higher content of insoluble divalent cations than soluble ones in shoot tissue.

Kwak, Young-Se ; Kim, Joon-Ho ;
The Korean Journal of Ecology, volume 17, issue 2, 1994, Pages 113~119
Vertical and horizontal distribution and seasonal changes of fine roots as well as inorganic nitrogen content in soil were determined in Quercus mongolica and Quercus acutissima stands in Mt. Taemosan, Seoul. The vertical distribution of fine rooth phytomass showed a power-functional decrease as descending soil depth. Fine root phytomass was 170 g
(46%) and 225 g
(47%) in top soil of 5 cm depth, and 370 g
and 480 g
from soil surface to 50 cm depth in Q. mongolica and Q. acutissima stands, respectively. Fine roots in relation to the distance from the nearest tree were evenly distributed horizontally in both stands. Fine roots phytomass in top soil of 5 cm depth reached a peak in June, and thereafter decreased gradually in both stands. Patterns of seasonal changes in fine root phytomass were closely related to inorganic nitrogen and moisture content.
Primary Succession on Talus Area at Mt. Kariwangsan, Korea
Lee, Kyu-Song ; Kim, Joon-Ho ;
The Korean Journal of Ecology, volume 17, issue 2, 1994, Pages 120~130
Stages of vegetation development on talus area were studied to examine temporal changes in species composition and vegetation structure, and to elucidate the mechanism of early patch formation. While ground coverage of lichens, which may form substrate for moss colonization and mitigate the heat-stress on rocks, decreased gradully, coverage of mosses increased slightly during primary succession. Ecological role of mossess related with water retention in community may be very important not only at pioneer stage but also at later stages because of little soil development on this talus area. Species diversity and species richness increased during the early stages of succession. Parthenocis년 tricuspidata and Sorbaria sorbifolia var. stellipa dominated in liana stage, Ulmus davidiana for. suberosa and Lindera obtusiloba in shrub stage, and Fraxinus rhynchophylla and Actinidia arguta in subtree stage, however, was composed of mixed forest of several tree species. U. davidiana for. suberosa, L. obtusiloba, Securinega suffruticosa and Rhus chinensis were relatively important woody species in early patch forming process. The results, however, suggested that early establishment on talus area might be strongly associated with chance for safe-site because both pioneer species and later species could take part in early patch forming process.

Lee, Woong-Sang ;
The Korean Journal of Ecology, volume 17, issue 2, 1994, Pages 131~141
One-year-old yellow-poplar (Liriodendron tulipifera L.) and sweetgum (Liquidambar styraciflua L.) seedlings were exposed to 0.10
and simulated acid rain at pH 3.0 for ten consecutive weeks. Shoot height growth (SHG), fresh weight (FWT), dry weight (DWT), apparent plastochron duration (APD) and foliar nutrient concentrations were measured. None of growth measurements, except the apparent plastochron duration (APD), were significantly affected by any treatment in yellow-poplar seedlings. APD was approximately 30% higher in seedlings exposed to
＋ pH 5.6 solution than any other treatment. Ozone significantly reduced SHG of sweetgum seedlings by 24% at the end of the ten-week fumigation. There were also significant effects of single and combined effects of ozone and simulated acid rain on APD in sweetgum. APD was significantly increased by 19.8% and 25.7% in seedlings exposed to
and pH 5.6 solution, respectively, and resulted in 46.1% higher APD in seedlings exposed to
+ pH 5.6 solution compared with seedlings exposed to
＋ pH 3.0 solution. Phosphorus and sulphur were significantly greater in seedlings exposed to simulated rain at pH 3.0 compared with pH 5.6 for both species. Foliar S concentration was higher in seedlings exposed to
＋ pH 3.0 than in seedlings exposed to any other treatment in sweetgum. Ozone significantly increased Ca in sweetgum seedlings, however, ozone reduced Ca in yellow-poplar. Ozone also reduced S and Mg in sweetgum seedlings.

Lee, In-Sook ; Kim, Ok-Kyung ;
The Korean Journal of Ecology, volume 17, issue 2, 1994, Pages 143~148
The relationships between microbial activity and physico-KDICical characteristics of soils were investigated in three golf courses of Kwanak, Gold and Korea Country Clubs, with different open years. The soil samples were collected in tee, fairway and rough. There were ranges of 4.80-5.55 in pH,
/ cm in conductivity, 10.96-16.73% in moisture content, 0.18-0.36g / g in water holding capacity, 3.68-5.39% in organic matter, and 0.10-0.25% in total nitrogen. Dehydrogenase activity(DHA) as an index of soil microbial activity was determined. DHA values of soil were
g / g in three courses and showed the order of Kwanak>Gold>Korea Country Club with open year. This indicates that DHA was affected by several fertilizer treatments rather than herbicide and pesticide treatments. DHA was significantly different with golf clubs as well as golf courses and positively correlated with water holding capacity and total nitrogen.
The Effect of Tread-Pressure on the Growth of Kummerowia striata
Kim, In-Teak ;
The Korean Journal of Ecology, volume 17, issue 2, 1994, Pages 149~157
To investigate the causes of distribution of Kummerowia striata (Thunb.) Schindl. mostly restricted on the roadside and reclaimed land, plant growth was analyzed under different of tread-pressures:
) and the control
). The matter production in the
decreased compared with that in the
, and those in the
continuously decreased so that its length growth gradually decreased and, in particular, the growth of leaves and nodule was suppressed. The number of leaves and roots tended to increase in the
. The water contents of roots following the increase of tread-pressure increased continuously. Following the increase of tread-pressure, T/R ratio and C/F ratio tended to increase. Kummerowia striata showed the highest growth in the
and showed 26% relative growth in the
compared with that in the
. This plant showed 8% relative growth in the
, which is excess to the tread-pressure
, the limit of growth in the plant. Because this plant grew continuously in the P
, the tread-pressure is regarded as an important factor affecting the roadside distribution of this plant.

The geographical distribution and soil characteristics of Korean Elaeagnus plants were investigated by literatures, field survey and soil analysis. Deciduous E. umbellata was distributed throughout the Korean peninsula including western and southern islands. Distribution area of evergreen Elaeagnus plants was classified into three groups; E. macrophylla and E. glabra belonged to group l occurring in the southern, western and eastern islands; E. submacrophylla to group 2 occurring in the southern and western islands; E. maritima and E. ankaii to group 3 in the southern islands only. Deciduous E. umbellata appeared euryeciously from poor soil to rich one, whereas evergreen Elaegnus plants appeared stenoeciously in haline soil near coast.

Lee, Hee-Sun ; Shim, Jae-Kuk ;
The Korean Journal of Ecology, volume 17, issue 2, 1994, Pages 171~183
Soil condition, total number of bacteria, soil amylase activity and microbial biomass
were measured at soil of different forest types. And the difference of the allelopathic effect was determined between fresh leaf extract of Quercus acutissima and Pinus rigida to the bacteria isolated from soil of different forest types. 1. Total number of bacteria in Carpinus laxiflora forest soil was 4~7 times larger than that in pinus desiflora forest soil. 2. Soil amylase activity was positively correlated with total number of soil bacteria and soil organic matter content. The amylase activity at F layer was 4~5 times larger than that at H layer, and that at H layer was 2~4 times larger than that at A layer. 3. Seasonal changes of microbial biomass showed a peak in summer, and vertical distribution of microbial biomass decreased with increasing soil depth. The microbial biomass in Pinus densiflora forest soil was larger than that in Quercus serrata forest soil. 4. Fresh leaf extract of Pinus rigida and Quercus acutissima showed an acceleration or inhibition effect on the growth of soil bacteria, and that of !. acutissima inhibited larger number of soil bacterial strains than that of P. rigida. 4.2% and 25% of soil bacterial strains isolated from soil of P. rigida and Q. acutissima forests were inhibited by fresh leaf extract of P. rigida and Q. acutissima, respectively.

The Quercus mongolica forest vegetation of Mt. Myongji was classified into two communities including four subunit communities and one typical subunit community by the Z-M method as follows: Acer pseudo-sieboldianum-Quercus mongolica community group Quercus mongolica - Isodon excisus community Quercus mongolica - Styrax obassia community Quercus mongolica - Lespedeza bicolor subunit coummunity Quercus mongolica - Aconitum longecassidatum subunit community Quercus mongolica - Rhododendrom schlippenbachii subunit community Quercus mongolica - Cornus controversa subunit community Quercus mongolica - Styrax obassia typical subunit community Acer pseudo-sieboldianum - Quercus mongolica community group was distributed over the upper region of the altitude 400m, and the differential species in the community were Carex siderosticata, Sephanandra incisa, Tripterygium regelii, and Fraxinus rhynchophylla. The vegetation patterns for the slope and azimuth showed that the highest importance value for Quercus mongolica forest was observed on the broad subxeric area, and for Carpinus cordata and Acer pseudo-sieboldianum on the wet site, for Acer mono, Styrax obassia, Fraxinus rhynchophylla and Symplocos chinensis for. pilosa on the xeric site. The best habitat condition for Quercus mongolica was found at a subxeric site at the altitude of 700-900m on southern slope and that for Acer pseudo-sieboldianum at the 700-1100m on northern slope.

The establishment by seeds and the maintenance by ramets of the autumn olive (Elaeagnus umbellata) population were investigated in the Namhansansung Provincial Park, Jungbu-myun, Kwangju-gun, Kyunggi-do. Seed production and germination rate were 3, 300
and 52%, respectively. The ramet formation in the population was classified into 4 types: stump type, creeping root type, lateral root type and secondary creeping root type. The subterranean creeping roots were 0.1~1.0 m in length, 4.5~14.0 mm in diameter and 0.06~0.2 m in soil depth. The number of ramets formed from a node was 1~21. The subterranean roots spread
, which began to be produced from 7~9 year-old individuals. The number of stems was 1~67 per stump, which was reduced by self-thinning from 2 to 14 year-old trees. The frequency distribution of stem diameter
showed a reverse J-shaped curve, suggesting that this population be maintained perpetually by their own ramets.

Hahm, Kye-Hwang ; Woon-Kee paek ;
The Korean Journal of Ecology, volume 17, issue 2, 1994, Pages 213~222
Songs recorded in Chirisam(1990~1993) and
(1992~1993) areas were analyzed to investigate the features and variances in songs of Great tit, Parus major. Songs of Great tits were identified, most of which were repetitions of phrases composed of high-frequency note and low-frequency note. The CV range of the Chirisan Great tit group was wider than that of the
area. ANOVA analysis level was highly significant (p<0.0001) for Chirisan area and
area. Inter-regional variance level was significant (p<0.05) in the maximum of low-frequency.
Transfer and Survival of Genes Resistant to Antibiotics in Soil
Lee, Geon-Hyoung ; Lee, Jae-Sei ;
The Korean Journal of Ecology, volume 17, issue 2, 1994, Pages 223~235
The transfer of plasmid-borne genes coding for resistance to antibiotics (Ampicillin, Carbenicillin, and tetracycline) among 16 strains isolated from Mankyong River was examined. The survival of donors, recipient, and transformants in sterile and nonsterile soil (the soil was amended with 12% vol/vol with the clay mineral, montmorillonite) was also studied. In sterile soil, the survival was prolonged in the order of donors, transformants, and recipient. The survival of donors, transformants, and recipient increased when the soil was amended with 12% montmorillonite, but not in nonsterile soil. In nonsterile soil, donors survived longer than transformants and recipient, but the survival of transformants and recipient showed no significant differences. The results of these studies suggest that genes can be transferred by transformation, and transferred genes can survive in soil for a considerable time.
