Effects of light and grazing on the biomass development of periphyton were evaluated using natural and artificial substrata (unglazed tile: 3.7×9.5x2cm) in a partially shaded 2nd order mountain stream. In open canopy (relative light input 20∼50%), a relatively high biomass (chl. a: 9.5±3.0 mg/m^2, n=25) was maintained than that of closed canopy(<6% of light input. 3.2±0.9 mg/m^2, n= 17). Due to shading and frequent rainfalls, biomass was lower during the summer than in the spring and winter. During the spring, colonization of periphyton on artificial substrata occurred faster than in winter and it took a minimum of 5∼6 weeks to reach the biomass of natural substrata (8∼9mg/m^2). When snails were allowed to freely enter the chamber (mean density: 114 ind./m^2) with artificial substrata, biomass accumulation (chl. a, AFDW) was low compared to the snail excluded enclosure (50∼90% of ungrazed substrata). It was concluded that the light input on periphyton biomass In a partially shaded stream played a more important role than glazing.

SLC6A19 which reported as a neurotransmitter was composed of seven minisatellites. In previous our study, the minisatellites variants of SLC6A19-MS7 showed the susceptibility for hypertension. When this minisatellte sequences were analyzed using the bioinformatic tool, USF1 (upstream transcription factor 1) was found in this region as a putative transcription factor binding site. USF1 is binding with E-boxes which has a consensus sequence of CACGTG. USF1 is a ubiquitously expressed transcription factor and involved in the transcriptional control of many genes including the molecular pathogenesis of cardiovascular disease. Thus, we investigated that the putative functional relationship between the minisatellites variants and susceptibility for myocardial infarction. A case-control study was performed that compared genomic DNA from 400 controls and 225 cases with myocardial infarction. There were no significant differences observed in the overall allelic distribution of minisatellites between controls and cases, which indicates that this polymorphism is not responsible for myocardial infarction susceptibility. Hence, we analyzed the five different minisatellites alleles from this study and characterized 14 different repeats units (Unit1~Unit14). Then, we evaluated the DNA composition, phylogenic tree, and pairwise distances of its repeats. The variability of each repeats differed from 2.33% to 16%. The phylogenic trees for the four SLC6A19-MS7 minisatellites exhibited very different shapes in their braches and distances, and present most common 8 repeats allele was the longest 14 repeats allele. Therefore, this result may help to understand for the evolutional level of the length of minisatellites.

Leaf litter breakdown rates of the Phragmites australis, Ziznia latifolia and Typha angustifolia were determined at the lower Nakdong River from Nov. 1998 to Sept. 1999. The relationship between leaf litter breakdown of three and abundance of aquatic invertebrates was investigated. Aquatic invertebrates collected in the litterbags were 11 family, 11 species(mean density: 222 ind./㎡, n=792), and Chironomidae was dominant. Mean density of Chironomidae in the litterbags were different according to the aquatic plant species: Z. latifolia(180 ind./㎡, n=264) T. angustifolia(187 ind./㎡, n=264) P. australis(95 ind./㎡, n=264). The breakdown of Z. latifolia was the shortest, and that of T. angustifolia was shorter than P. australis. Overall, the breakdown rate at floating layer was faster than that of submerged layer in all of three species and differences of the breakdown rate between open bags and closed bags were not found.

洛東江 河口堰 축조 후의 水生管束植物의 現存量 변화에 관한 硏究

윤해순 동아대학교 환경문제연구소 1993 硏究報告 Vol.16 No.1

Seasonal changes in biomass of vascular hydrophytes in Jukrim branch, the dead west branch of Nakdong river, was estimated from July 1991 to May 1992, and was compared to that before the construction (1984-1986) of Nakdong barrage. 1. The area of vascular hydrophytes distribution, and their biomass, decreased in summer months, compared to those before construction of the barrage. 2. Percent composition of floating plants(Trapa spp.) and semifloating plants(Patamogetom spp.) increased significantly, while that of submerged plants (V. asiatica and Najas spp.) decreased. These results suggest that the water body of Jukrim branch in the process of eutrification, and indicates the need for proper treatment of industrial and farmland wastewater before discharge into Jukrim branch.

尹解順,元炳旿 東亞大學校附設基礎科學硏究所 1985 基礎科學硏究論文集 Vol.2 No.1

Aquatic macrophyte vegetation as foodplants for waterfowl in Jukrim and Maekdobranches, Yongwon inlet and Junam reservoir was investigated from April 1984 through April 1985. These areas interrelated to the total Nakdong wintering ground for waterfowl. Aquatic macrophyte flora in Jukrim branch included 14 species of 11 genera of 9 families, and 21 species of 16 genera of 11 families in junam reservoir. In Yongwon inlet Zosterra marina was only distributed. In these areas except Yongwon inlet, dominant species was Trapa japonica and the fruits, not the leaves and stems of it was very important as food source for swans and geese. The biomass of the aquatic weed vegetation in Jukrim branch increased quickly from April to July 1984 and continued to grow until October of the same year. However, it remarkably decreased from October to November as it was consumed by migrating and wintering waterfowl. Thus, the foodplant biomass dropped sharply in the midwinter. The biomass of early April in 1985 was 1.6g??, which was only 0.8% out of total biomass in October the previous year. All above results show that aquatic plants are under heavy feeding pressure in Nakdong estuary and related area.

洛東江 河口의 植生에 관한 硏究 : The Biomass of Foodplants for the Migration Birds 철새의 먹이植物을 中心으로

尹解順 東亞大學校 大學院 1984 大學院論文集 Vol.9 No.-

The estimation of biomasses of such foodplants as Scirpus tirqueter, Zostera noltii, Potamogeton crispus and vallisneria asiatica was carried out at the estuary and related area of Nakdong River, since these plants have been known as foodplants for the birds. Among these plants, especially, the total biomass of Scirpus and Zostera were remarkably reduced from Oct. to Jan., and then the rate of the reduction decreased moderately from Jan. to Apr. The underground parts of Scirpus decrease to 7.6% during the winter in the muddy area. And the biomass reduction of Zostera was similar to that of Scirpus. These results suggest that such plants are important as feeding materials for the herbivorous and omnivorous birds and these plants are under the relatively heavy feeding pressure.
