  • Community structure of benthic macroinvertebrates was investigated from Gigye stream, Pohang, Korea from May to November, 2007. As results, total of 108 species of macroinvertebrates under 49 families, 15 orders, 5 classes in 3 phyla were identified. The number of species was the most abundantly revealed in aquatic insects (class Insecta) with 86 species (82.6%) under 7 orders. The phylum Mollusca (10 species, 9.2%) and the phylum Annelida (6 species, 5.6%) were followed in order. In the class Crustacea, 6 species (5.6%) were distributed. In aquatic insects, the order Odonata was the most abundant taxon (20 species, 23.3%). Seventeen species (19.8%) of the order Ephemeroptera and 16 species (18.6%) of the Coleoptera were followed. The primary dominant species in the stream was Cloeon dipterum of Ephemeroptera. For community analysis, the values of diversity index (H'), evenness index (J'), dominance index (DI) and richness index (RI) were studied and the average values of them were 5.65, 0.84, 0.13, and 13.18, respectively.

  • This study was designed to establish Korean food culture by analizing 17 sets of Jinyounuigue(진연의궤) Jinchanuigue(진찬의궤), and Jinjarkuigue(진작의궤) which were the records of royal party procedures in Yi dynasty. Side dishes were classified into 20 groups in this study ; Tang (場) 19, Jungol (전골) 3, J'im 18, Jun (전) 20, Jock 14, Pyunuk (片肉) 14, Cho 12, Hyae 17, Po 8, Chae 3, Bung 1, Nanri 1, Sooran 1, Sookran 1, Jaban 1, Kimchi 2, etc. all of 140 different kinds of side dishes. There was no tendency in omission or addition of food materials. Food materials were beef, pork, lamb, chicken, duck, peasant meat, dock's egg, fish, shellfishes, mollusca, curstacea, seaweeds, vegetables, fruits, beancurds, muk (a starch jelly), d'ock, muchrooms, etc. Seasonings were soysauce, pepper, sesame oil, ginger, green-onion, garlic, bean paste, ginger powder, red pepper powder, red pepper paste, salts, vinegar, honey, sesame power, etc.

  • The morphology of molluscan egg capsule is generally regarded as being species specific (Turner, 1992), and form and structure of the egg capsule reflect the degree of anatomical complexity of the reproductive organs (Fretter & Hian, 1984). Ceratostoma rorifluum and Ocinebrellus inornatum are common and widespread muricid species found throughout the Korean rocky and boulder shores, and Neptunnea constricta is found frequently from continental shelf of the eastern sea of Korea. In spite of their predominance along the Korean coasts, morphology of their eggs and egg capsules is unknown so far. The purpose of the present study, therefore, is to provide descriptions and illustrations for identifying egg capsules of the foregoing 3 stenoglossan gastropod species. (omitted)

Sex Ratio, Imposex and Penis Morphology of the Four Intertidal Muricid Species (Thais clavigera, T. luteostoma, Ceratostoma rorifluum & Ocinerberllus inornatum) (Mollusca: Gastropoda: Muricidae) in the Korean Coasts

  • Sex ratio of a population is a key factor to determine reproductive rate of the population. If the population has skewed sex ratio to the male, the population size may decline gradually at an area which it inhabits, and, furthermore, if a species plays an ecologically important role in its community (e.g., a keystone species in Paine, 1966), its potential reproductive rate will be to form a characterized community because community structure is strongly influenced by the abundance of the ecologically important species (Hughes, 1986). A number of workers (e.g., Bryan et al., 1986 in Nucella lapillus; Spence et al., 1990 in Thais haemastoma) suggested that high frequency and/or late stage of imposex might affect the female mortality and normal reproduction adversely. Consequently, the imposex could affect sex ratio of natural population of some neogastropod including thaisid species. (omitted)

  • Seasonal variation of species composition in marine organisms around Oryukdo of Busan was investigated using a gill net between 2009 and 2011. A total of 82 species, 52 families, and 6 taxa were collected during the sampling periods. Species were included two species in Cnidaria, one in Urochordata, 12 in Mollusca, 12 in Crustacea, seven in Echinodermata, and 48 in Pisces. The dominant species were Crepidula onyx, Asterina pectinifera, Ceratostoma burnetti, Asterias amurensis, Anthocidaris crassispina, and Trachurus japonicus. These six species accounted for 48.4% in the total number. Diversity indices were highest in spring 2009 (2.77) and lowest in spring 2011 (1.66). Seasonal variation of species composition and abundance in marine organisms corresponded with the water temperature.

  • The bivalve Malleus regula ($Forssk{\aa}l$ in Niebuhr, 1775) is reported for the first time from Korea. This is the second species of Malleidae reported from this country. Since the species is quite variable, comparisons were made with the original description and descriptions in the literature; some taxonomic comments were also made. Global warming and possible changes in the northward-flowing Tsushima Current may account for the addition of new mollusk species to the island's fauna.

  • The survey of the macrobenthic animals near Hwasoo wharf, Inchon, Korea was carried out during October, 1995 through September, 1996. Polychaeta was the most dominant taxons were Mollusca and Crustacea. Only one species of Echinomermata, Protankyra bidentata, was collected. Capitella capitata collected from site 1 indicates that the site was more polluted, and Heteromasmus sp. collected from sites 2 and 3 suggests that these sites were polluted with organic materials.

  • Conchodytes nipponensis (De Haan, 1844), a caridean shrimp living in the mantle cavity of a pen shell (Atrina pectinata) is reported for the first time from Korea. It was collected from a depth of 15 m depth. Its morphology is described and illustrated, and a color image of a living specimen is provided. This is at the same time the first record of the genus Conchodytes, and the first record of a bivalve mollucs associated shrimp, from Korea.
