To know of the biological basic method that can improve the environment of the organisms that inhabit at Deokjin Park. We studied the flora and the fauna in Deokjin Park on June, 1996. The study was surveyed and researched according to the items floras, phytoplanktons, insects and vertebrates. The floras are composed of eleven varieties, one forma, eighty-three species, eighty-four genera and forty-nine families. In the lake of Deokjin Park, the dominant species were Nelembo nucifera and Spirodela polyrhiza. The authors thought that those species be artificially excluded in winter for the improvement of the quality of water. The phytoplanktons were composed of forty genera, eighteen families, ten orders and six classes. Among those, Anacystis(=Microcystis) and Anabaena that make eutrophication, were distributed in the lake of Deokjin Park. The fauna of insects were composed of forty-one species, thirty families and eleven orders. The authors observed seven species of fish, two species of amphibian, three species of reptile, seven species of the bird and one species of mammal. Among those, Bull-frog and Blue-turtle as exotic species must be excluded by artificial methods for the other native organisms of the lake of Deokjin Park.

Seahorse is an interesting organism for the study of its conservation as well as development as an marine ornament fish. To investigate the ecological characteristics and fish fauna around the habitat of such an endangered species, fishes were collected from the seahorse habitat. A total of 161 fishes were classified into 8 families and 11 species including two species of seahorse, Hippocampus mohnikei and H. coronatus representing 1.9% and 1.2%, respectively, of the population. The most dominant fish species in the area was Takifugu niphobles accounting for 30.4% of the population. The predators of the seahorse such as Acanthopagrus schlegeli, Lateolabrax japonicus and Lateolabrax maculatus were found in the relative abundance of 0.6%, 5.6%, and 11.8%, respectively. The relative abundance of H. coronatus ($0.96\;ind./1,000\;m^2$), H. mohnikei ($0.97\;ind./1,000\;m^2$) and the other coexisting fishes are similar in all the areas investigated (P>0.05).

The pine mushroom fruit body have a harvest only from natural pine forest instead of artificial culture like other edible mushrooms until now on. We investigated the interrelationship between pine mushroom colonies and insect/invertebrates fauna, and changes of their seasonal populations. Two famous pine mushroom producing district were selected on Bong-wha and Gan-sung Eup, and were surveyed on the ground and in the soil with/without pine mushroom hyphae per month from June to November, 2005. There was some difference in collected Insects and invertebrates between two producing districts. Total number of collected species and individuals were 73 and 22, and 63 individuals with 19 species in Bon-wha and Gan-sung area, respectively. Otherwise, there were many mites and nematodes were living in soil with mushroom hyphae. The population densities of mites were Increased to November from June, however, the population of nematodes were fluctuated with low in hot weather and high in cool.

The fish fauna and Community were surveyed from April 2000 to September 2001 at 23 stations in the nam river, the first tributary located to the lower reach of the Nakdong River system. During the study period, 39 species belonging to 29 genera and 11 families were collected. Of which 14 species are endemic species or subspecies in Korea. Introduced species from other river system, O. bidens had not been collected at all after the report of Yang (1973) but many individuals were captured at main stream and tributary in this survey. Introduced species from abroad M. salmoides increased at most of stations. Dominant species in main stream were Z. platypus, O. bidens and H. labeo. On the contrary, Z. temmincki, Z. platypus and S. gracilis majimae dominated the tributaries. Diversity indices of main stream and tributaries were 0,979 and 0.966 respectively. St. 3 of main stream and St.1 and 16 of tributaries had high diversity indices (1.05, 0.962, 0.956) and lower dominant indices (0.102, 0.369, 0.200). As a whole, dominant index was 0.160, diversity index 1.044 and evenness index 0.656. It indicated that the community structure of this river was stable and diverse relatively.

Macrobenthic community was studied in Deukryang Bay, southwestern coast of Korea, in November 1991 and Januavy 1992. Hacrobenthic fauna consisted of 118 species with 20,767 individuals. The number of species and occurrence frequency of the major groups were as follows: 52 polychaetes species $(44.1\%)$, 45 crustaceans species $(38,1\%)$, 14 mollusks species $(11.9\%)$ and 7 other group species $(5.9\%)$. The mean density was $1432.2ind/m^2$. The density of major groups showed that mollusks was 920.4$(ind./m^2)$, polyrhaetes 275.8$(ind./m^2)$, and crustaceans 219.6$(ind./m^2)$. The dominant species were Musculista senhousia (Bivalvia), Eteone longa (Polychaeta), Nippopisella nagatai (Amphipoda) with density, 632.8$ind./m^2$, 37.8$ind./m^2$, and 35.3$ind./m^2$, respectively. This area could be divided into four areas by the cluster analysis based on the species composition.

Fish fauna, difference of stable isotope ratio between freshwater and seawater, and trophic guilds of freshwater fishes were investigated in the lower Geum River. The study was conducted in 2011, and total study area was about 30 km of 20 km upstream and 10 km downstream from the Geum River estuary barrage. Only freshwater fishes were used for analyzing trophic guilds, and discriminant function analysis (DFA) was utilized to reclassify trophic guilds based on stable isotope ratio. Fish fauna in freshwater and seawater areas were entirely different each other, but small number of migratory species such as Coilia nasus and Chelon haematocheilus occurred both areas. Other species were not collected in the different areas because they did not have physiological ability to adapt different salinity concentrations. Stable isotope ration of two areas were different considerably due to food sources. Estuary and seawater fishes uptake food sources originated from marine, and freshwater fishes were from freshwater and terrestrial. Some migratory species showed reverse stable isotope ratio. Even though they collected in freshwater, they showed stable isotope ratio of seawater. This is because ecological characteristics of each species. Trophic guilds of freshwater fishes were reclassified by DFA, and showed slight difference with literatures. However, because this result is related with ontogenetic shift of species, more studies are needed to explain exact and correct trophic guilds. Stable isotope ratio can be changed among regions, seasons and ontogenetic stage, thus we always consider these aspects when analyzing results to get a right answer.

The study was performed to investigate the community structure of macrobenthic fauna during June 2005, in Hallyeohaesang National Park from Korea Strait. A total of 284 macrobenthic fauna were collected. The overall average macrobenthic density and biomass were 2,002 individuals m$^{-2}$ and 154.92 gWWt m$^{-2}$, respectively. Based on the Lebris (1988) index, there were 20 species accounting for approximately 47.64% of total individuals. And the highest densities were found in the polychaetes Scoletoma longifolia, Isolda pulchella, Mediomastus californiensis, Minuspio multibranchia, Tharyx sp. 1 and the bivalve Theora fragilis. On the other hand, the top twenty species made up 70.47% of the total biomass while the three most abundant, the echinoderms Schizaster lacunosus, Amphiura vadicola and the bivalve Fulvia mutica. The conventional multivariate statistics (cluster analysis and non-metric Multi-Dimensional Scaling) applied to assess spatial variation in macrobenthic assemblages. As a result of cluster analysis and nMDS ordination, this study area was divided into two different groups of stations and species. In case of station, there are two groups: one is a mud dominated station group and the other is dead shell and sand dominated group. And the 2 faunistic groups were established as follows: 1) a group of relatively higher abundances in mud dominated sediment. There were numerically dominated by the polychaetes Magelona japonica, Sternaspis scutata, Paraprionospio pinnata, Tharyx sp. 1 and the amphipods Monocorophium sinense and Eriopisella sechellensis. 2) a group of relatively higher densities dead shell and sand dominated sediment. These groups were characterized by the polychaetes I. pulchella, M. multibranchiata, the amphipods M. acherusicum, Gammaropsis japonicus and the echinoderm A. vadicola.

A preliminary list of the following four tephritoid families is provided including 30 Korean species, of which 12 are new to Korea: two Lonchaeidae, three Pallopteridae (two new to Korea), 17 Platystomatidae (two new to Korea), and eight Ulidiidae (all new to Korea). This list is mainly based on the insect collection at the Yonsei University Wonju Campus and on previous publications concerning these taxa. Although a full taxonomic revision for each family is required in the long term, this preliminary list will provide a useful starting point to further investigation of these families. For the other three tephritoid families known in Korea but not treated in the present study, 89 species of Tephritidae, 14 species of Pyrgotidae, and one species of the rare family Ctenostylidae have been reported previously. A total of 134 species in seven families are officially recognized for the Korean fauna of the superfamily Tephritoidea.

The fly genus Orchisia Rondani belonging to the tribe Coenosiini of the family Muscidae, known to be distributed throughout old world, is newly recorded in Korean fauna, along with the type species O. costata (Meigen, 1826). This genus has been known to include only two species, O. costata and O. subcostata Cui, Xue et Liu, 1995. These flies can be readily distinguished by the other related taxa of the tribe Coenosiini in having prominent color pattern on wings. The Korean population has been observed on the grass vegetation at marsh area. Photographs of external features and male genitalic characters are provide.

The Zopheridae Solier consisting of members from three previous families, Zopherinae Solier, Monommatinae Blanchard and Colydiinae Erichson, is considered the taxonomically most challenging group, and comprises more than 1,700 described species worldwide. The members of Zopheridae represent diverse morphological variations, and are difficult to separate morphologically from other tenebrionoid families. Two Zopheridae genera, Colobicus Latreille and Lasconotus Erichson, are identified for the first time in Korea, and two wood-boring species, C. hirtus (Rossi) and L. niponicus (Lewis), are newly reported in the Korean fauna. A key to the genera of Korean Zopheridae, and diagnoses, habitus photographs, and illustrations of diagnostic characters of the two species are provided.
