2003년 11월과 2004년 4월의 2회에 걸쳐 상용조류발전소 건설 예정지인 울돌목에서 발전소 건설로 인해 야기될 주변생태환경의 변화를 파악하기 위해 4개 지점의 주변 암반조간대에 형성된 기존의 부착생물상 조사가 수행됐다. 울돌목 주변의 암반조간대에 형성된 부착생물상은 서식 형태에 따라 크게 대형해조류(Macroalgae)를 포함한 고착생물, 소 이동성 부착동물, 이동성 소형 무척추동물 등으로 구분된다 부착생물상은 서식양상에 있어 각각의 정점별 특이성이 관찰되었으며, 이는 각기 다른 비생물학적 요인에 따라 지역 특유의 서식환경이 조성되어 있음을 시사하는 간접적인 결과로 간주된다. 이같은 지역 간 생물상 차이는 조위에 따른 수직분포 분석결과 주로 중부조간대를 중심으로 형성된 생물상에 따라 대별되고 있음이 발견되었다.

A survey was carried out two times at 11 localities on the marine molluscan fauna of Saemangeum during the periods from August 3rd to August 5th, and from August 23rd to August 25th 2003. The total number of molluscan species identified in this study was 88 species in 40 families, and among them 51 species in 34 families include Eurytrochus cognatus were new to the fauna of Saemangeum. In addition to the previously described 58 species in 31 families, a total of 109 species in 48 families of marine mollusca have been reported at Saemangeum up to date.

The aim of this study was to investigate the distribution of soil biota across forest types and soil depths in Gwangneung Experimental Forest. We selected 5 sites, which are 3 deciduous- and 2 coniferous forests. The abundance of microflora in these areas was analyzed by the phospholipid fatty acid (PLFA) indicators, and the density of mesofauna was measured by the abundance of nematodes and microarthropods. The abundance of soil microflora was higher in the A layer than in the B layer based on the PLFA indicators, but there were no differences between deciduous and coniferous forests. Average density of nematodes was higher in the A horizon than in the B horizon. The density of fungivorous nematodes was higher in the deciduous forests. Mean densities of Collembola and Oribatida were 44% and 42% of microarthropods in soil samples, respectively. The results of microbial PLFA indicators were significantly correlated with the density of their consumers, which reflected that the food web in fungi- and bacteria-based soil developed in this forests. This study suggested that the distribution of soil organisms largely separated by soil depths and was slightly affected by the forest type in the Gwangneung Experimental Forest.

Thirty one marine molluscan species were added to the malacofauna of Dokdo Island, Korea based on the samples collected from April 2006 to August 2008 with SCUBA diving. As a result, one hundred six marine molluscan species were recorded from Dokdo Island hitherto.

Organic farming is necessary to sustainable agriculture, preserve biodiversity and continued growth the sector in agriculture. In organic farming, reduced usage of chemical agents that adversely affect human health and environment, employing amino acids and oil cake fertilizer, plant extracts, and microbial agents are used to provide safe agricultural products to consumers. To investigation microbiome structure, we proceeded on the pepper plant with difference fertilizers and treatments in organic agriculture for three years. The microbial communities were analyzed by the next generation sequencing approach. Difference soil microbiota communities were discovered base on organic fertilizer agents. Occurrences of virus and anthracnose diseases had a low incidence in conventional farming, whereas bacteria wilt disease had a low incidence in microbial agents treated plots. Microbe agents, which applied in soil, were detected in the microbial community and the funding suggested the applied microbes successfully colonized in the organic farming environment.

To study the characteristics of rocky intertidal invertebrate fauna on the coastal areas of the East Sea, seven regions including Dokdo, Ulleungdo, Gyeongju, Pohang, Yeongdeok, Uljin, and Gangwondo, the common species ratio (%) and similarity index using Bray-Curtis similarity matrix were calculated. The contributed species for dissimilarity between Dokdo and the other East Sea's coastal areas were selected by using SIMPER. The common species ratio and the cluster analysis showed that Ulleungdo presented the highest similarity. However, Yeongdeok showed the highest similarity in the eastern costal areas, and Gangwondo showed the lowest one. However the cluster analysis revealed the discrimination of the rocky intertidal invertebrate community on Dokdo with others region caused by the particularity of rocky shores exposed to strong wave action and by the particular distribution of rocky intertidal invertebrate fauna in Dokdo.

1992년 7월부터 1997년 7월까지 거제도 연안 14개 지점에서 채집된 표본들을 동정, 분류한 결과 4강 63과 149종이 밝혀졌고 이 중 한국 미기록종 1종 (Odostomia omaensis 기생이빨고둥)을 포함하여 45종 91종은 거제도 미기록종이었다. 거제도 해산 연체동물은 과거의 문헌에 기록된 것을 포함하여 다판강 5과 13종, 복족강 38과 105종, 이매패강 22종 45종, 굴족강 1과 1종으로 총 66과 164종이며 이에 대한 목록과 한국미기록종에 대한 재기재를 하였다.

This study was conducted to search the effects of debris barrier on the benthic macroinvertebrate. Gimcheon was selected as the survey site as it has relatively stable ecosystem with constantly running water. The survey was conducted 6 times before and after the construction of debris barrier from February in 2009 to October in 2010. In the first survey before construction, the identified species were 36 species belonged to 22 families, 9 order, 4 class, and 4 phylum. The figure slightly decreased to 30 species belonged to 18 families, 7 order, 2 class, and 2 phylum in the sixth survey after construction. Before construction, occupation ratio of EPT taxa was showed in the following order: Ephemeroptera (50.0%, 85.0%), Trichoptera (35.3%, 10.0%), and Plecopteran (14.8%, 5.0%). After construction, it was showed in the following order: Trichoptera (50.3%, 68.0%), Ephemeroptera (42.1%, 29.4%), and Plecopteran (7.5%, 2.7%). Ephemeroptera was the highest before construction. Trichoptera increased rapidly after construction. The Diversity, Richness, Evenness, and Dominance indices were all turned low in the second survey right after the construction. However, each index tended to increase with the course of time. In Functional Feeding Groups, GC type was the highest of 60.7% before construction. After construction, SC(53.1%) and FC(35.4%) increased rapidly and they became stabilized since the third survey. The result of this study reveals that debris barrier greatly affects the Aquatic Ecosystem right after its construction, but the system becomes stable and returns to normal with the course of time (about 18 months). Therefore, the study considering various influence factors such as time is required to recover completely through further long-term monitoring.
