Reduction of Aluminum Toxicity by Calcium and Magnesium in Pines
Ryu, Hoon ; Joon-Ho Kim ;
The Korean Journal of Ecology, volume 19, issue 3, 1996, Pages 193~199
Alleviation of Al toxicity by Ca and Mg was studied with seedings of Pinus densiflora, P. rigida and P. thunbergii under the solution culture. The seedlings were cultivated in the enriched Can and Mg nutrient solution with 2, 000
Al for three weeks. The hightest total root lengths of P. densiflora, P. rigida and P. thunbergii increased by 21, 33 and 133% in Ca enriched solution, and 23, 44 and 107% in Mg enriched solution, respectively. Ratios of lateral root to main root length increased significantly in Mg enriched solution, and redution of Al toxicity was more affected by enriched Mg than by enriched Ca. Al content in tissue was reduced by enriched Ca and Mg.

Selection of Al tolerant woody plants, and possibility of reforestation with the Al tolerant plants in soil conditions with different Al content, topography and slope exposures were studied on the slopes around Yeocheon Industrial Complex. Root growth in length of plants grown in 1/2 Steinberg solution decreased with increased Al concentrations of the solution. Relative root length showed that Paulownia coreana, Celtis sinensis and Firmiana simplex were sensitive to
Al, Pinus koraiensis, Alnus japonica and Ligustrum japonicum were intermediate, and Pinus rigida, P. densiflora and P. thunbergii were tolerant to
Al. Coniferous plants appeared to be more tolerant to Al than deciduous ones. Soil pH was 4.2 and Al content was 509 ppm in average around the Yeocheon industrial complex. Al content and soil acidity were more deteriorated on the foothill and slope facing to the pollution source from the industrial complex than on the ridge and opposite slope.
Characterization of Water and Sediment Environment in Water Shield (Brasenia schreberi) Habitats
Kim, Yoon-Dong ;
The Korean Journal of Ecology, volume 19, issue 3, 1996, Pages 209~216
In order to identify the habitat characteristics of water shield (Brasenia schreberi), water quality and sediment characters were investigated. Water shield had peculial habitats such as old reservoir, developed basin-like reservior, a water depth within 1.5 m, constant water level, and thick sediment layer at the bottom. The species had very dense populations under the favorable growing conditions and occasionally grew together with Utricularia japonica. When water shield decreased, Nelumbo nucifera, Nuphar japonicum and Zizania latifolia increased. Natural populations of water shield need protection because it is endangered by the human activities and their harvest. The optimal conditions for the growth of water shield was near neutral pH. low conductivity and low turbidity. Therefore the input of pollutants should be controlled for its growth. The inorganic ion contents such as K, Mg, and Na were higher in the water shield growing area. Especially iron content of the sediments in the reservoirs with water shield was nearly five times as high as that in the reservoirs without water shield. thus iron might be one of the major limiting factors for the growth. It was considered that molybdenum can be another major factor because water shield is a nitrogen fixing plant.

Choi, Youn ; Jong-yeon Kim ; Yong Tae Rho ;
The Korean Journal of Ecology, volume 19, issue 3, 1996, Pages 217~222
For the ecological study on the gobioid (Favonigobius gymnauchen), samples were collected in the Korean coasts from 1983 to 1995, and the process of ovarian maturation, spawning season, settling period of young individuals and growth were investigated with the specimens collected from Kunsan coast. The ovarian egg development of this species underwent three stages; growth stage from March to April, maturity stage from May to June and spawning stage in July. All the adults died after spawning in late July. Young individuals of total length 10 mm began to live a bottom life in the tide pool of shallow waters in early and middle August. The total length of these individuals reached about 42.1 mm (mean 36.7 mm) in late November. The largest specimen examined in this study was 85.0mm of male. After that time, individuals of this species inhabited in subtidal zone from December to May of the next year. The Favonigobius gymnauchen is distributed at 17 areas of shallow waters and estuaries in the western and southern coasts of Korea.

Kim, Chang-Hwan ; Bong-Seop Kil ;
The Korean Journal of Ecology, volume 19, issue 3, 1996, Pages 223~230
Five measurements of species diversity (richness index, diversity index, evenness index, dominance index and species sequences-importance curve) and their relationships with sltitude, tree age and community type were studied in
National Park, Korea. Altitude and tree age were the major variables explaining the differences of species diversity in the whole forest. Species richness index, diversity index and evenness index of Quercus mongolica and Pinus densiflora communities were lower than those of Carpinus laxiflora, Q. serrata, Fraxinus mandshurica, Q. mongolica - P. densiflora communities than that in the other communities. The species sequence-importance curve of the forest communities in
coincided with the ideal curve calculated by the lognormal-distribution theory.

The germination responses of Cassia mimosoides var. nomame seeds to temperature were examined under various conditions. The temperature range allowing germination was
, and the linear relationship between the germination rate and temperature appeared to exist between
The total thermal time required for germination (10~80%) of C. mimosoides seeds ranged from 259 Kh (degree Kelvin
hours) to 421 Kh and base temperature range was relatively constant, i.e.,
. In the increasing temperature (IT) regime, C. mimosoides seeds started to germinate at
and showed greater germination rate with increasing temperatures. The final germination rate was 64% at
. On the other hand, in the decreasing temperature (DT) regime, the seeds began to germinate at
, and the final germination rate was 52% at
. An induced dormancy occurred at
in the DT regime.

To determine the accumulation and distribution of heavy metals in plants and soils of roadsides, the leaf and bark of Ginkgo biloba and Platanus occidentalis, and the soil were sample from Masan-city roadside and Chinhae forest land in July and November, 1994. The content of heavy metals from all the samples in Masan-city area was much higher than that in Chinhae forest land. The amount of heavy metals in soil was higher than those in plant parts of boty trees. The total amount of heavy metals of the bark was higher than the leaf of G. biloba plants. But that of the bark was less than the leaf of P. occidentalis. Heavy metal content in plants (leaf, bark) varied among elements and collections. The concentrations of heavey metals in both trees were in the order of Zn > Cu > Pb > Cd. The concentrations of the four heavy metals in leaf and Zn in soil in G. Biloba were seasonally changed. Whereas those in P. occidentalis were not significantly changed. And there was a high correlation between the concentrations of Pb and Cu in both trees.

Choi, Seong Sik ;
The Korean Journal of Ecology, volume 19, issue 3, 1996, Pages 251~260
The effect of forest fire on soil microarthropod fauna was investigated in the Inhoo Park, located at Deokjin-gu, Chonju city, where fire burned about 2 hectares on April 5, 1994. Vegetation of the area was covered with mixed forest such as 20 to 30 year old black locust, alder, and pine gree, etc., and also rich in understory plants, dead leaves, twigs, etc. The soil samples were taken from burnt soil and near-by control site on April 10, June 6 and Oct. 22 in 1994, and June 26, 1995. Soil microarthropods were extracted using Tullgren apparatus for 72 hours. Soil microarthropods collected in this experiment were 8, 013 at control and 3, 805 at the burnt site making a total of 11, 818 from 5 classes. Therefore, appearance of microarthropods was reduced to 52.5% at burnt site. Dominant animal groups were Acari (45%) and collembola (46%). The reduced rate of soil animal density by fire damage was 52.5% of the total soil microarthropods accounting 36% in Acari and 70% in collembola. The reduction of soil animal density by fire was 65.3% by habitat destruction and 51.7% by diret shock from fire heat. In Collembola, 89% was reduced by habitat destruction. Oribatid mites collected at sample plots included 29 families, 47 genera and 58 species. Forty-two species at burnt site and 47 species at unburnt site were identified, of these 32 being common species at both sites. The density ratio of soil animals at the burnt sites and those at unburnt sites was 38.6% va 61.4% resulting in 37% reduction due to fire. The dominant species with more than 5% in relative density were Trichogalumna nipponica (7.3%) and Eremobelba japonica (5.8%) at unburnt site, shereas 5 species including Eohypochthonius crassisetiger (8.5%) at the burnt site. The number of these species were 32.1% of total number. MGP analysis based on the number of oribatid mites indicated GP type at both unburnt and burnt sites, revealing domination of the P group in oribatid mites.

To investigate the degree of contamination from Korean coastal region, the concentrations of Cu, Pb, Zn and Cd in sediments, seawater and oyster (Crassostrea gigas) at Masan Bay, Onsan Bay, Daesan industrial complex and their control areas were analysed. Values for sediments, seawater and oyster in the industrial complex coastal region were higher than those in the control area except for seawater in Daesan. The values for dissolved phasc of Cu, Pb, Zn and Cd in seawater showed 0.3~1.75
, respectively. The concentrations of Cu, Pb, Zn and Cd in sediments werd 12.0~47.8
, respectively. The concentrations of Cu, Pb, Zn and Cd in oyster showed 12.1~85.6
, 1, 070~3, 250
, respectively. The contents of heavy metals in oysters at industrial complex coastal region showed that they were not seriously contaminated compared with those of Mussel Watch (1992).

This study was aimed to observe the effects of municipal sewage sludge as a organic fertilizer on the growth and KDICical omposition of Altari radish (Raphanus sativus). The accumulation rate of heavy metals of the sludge in the radish was also observed. Municipal sewage sludge of Taejon City was applied to the soil of Pai-Chai University Farm to make 6 gradients of sludge contents in the soil. Root weight of Altari radish was affected significantly by N and P contents in the soil. The longest leaves and roots were produced in the control group, in which urea was applied as nitrogen source to the soil. Even though any other sludge-applied groups produced shorter leaves and roots than the control group, the length of the leaves and roots and the weight of the whole plant of the radish tended to increase with the increase of the sludge application. Contents of N, K, Ca and Mg in the radish were not significantly different among those in 6 experimental groups, but P contents in leaves varied among the 6 groups. Zn content of spring Altari radish treated with 200% sludge was 57.6 mg/kg. It is the highest contents among 6 experimental groups. Contents of Zn, Mn and Cd were higher in leaves than in roots, but less than those in market vegetables. From the above results, it is concluded that municipal sewage sludge can be applied as organic fertilizer to the growth of Altari radish. But this sludge could not be applied under our current regulations, which must be reviewed at intra-governmental leavels.
