  • 해양의 저서동물은 이동성이 없어 오염 지표종으로 사용되는 종류가 많으며, 특히 환형동물문의 다모류 가운데 그 종류가 많다. 대표적인 경우가 버들갯지렁이과 (Capitellidae)에 속하는 종들이며, 이들 가운데 Capitella capitata는 전 세계 유기물 오염해역, 저층 빈산소 수역 (0.2∼2.5 m1/1) 및 유류 오염해역 둥에서 가장 잘 출현하는 종으로 알려져 있다 (Pearson and Rosenberg, 1978). (중략)

  • A capitellid species, Heteromastus filiformis ($Clapar\grave{e}de$, 1864) is newly reported from Korean waters with the description and illustrations. Korean materials of the present study show several characteristics generally agreed well with the previous descriptions of H. filiformis as follows: the thorax is composed of the first achaetigerous peristomium and following 11 thoracic chaetigers; the capillary chaetae are present on the thoracic chaetigers 1-5 and narrowly bilimbate; the thoracic hooded hooks are appeared on the chaetigers 6-11 and have indistinct nodes on the shaft and several teeth above the main fang; the abdominal hooded hooks possess distinct nodes on the shaft and a few teeth above the main fang; the branchiae appearing on the posterior abdominal segments are the broadly-based and rounded lamellae projecting posteriorly. The authors reviewed the taxonomy of Heteromastus with a comparison of morphological characteristics among worldwide species, and provided a key of them.

  • Macrozoobenthic community structure was studied on the mud-tidalflat around Mokpo coastal area, Korea, from September 1995 to May 1996. Ten sampling stations were chosen along the 1km transect with a 100 m intervals. Triple macrozoobenthos sampling were conducted with a stainless box core sampler (size $13{\times}22{\times}30$ cm) at each station on the seasonal basis. A total of 119 species of macrobenthos was sampled with a mean density 2,357 $ind./m^2$ and biomass of 180. 94 $g/m^2$ during the study period. Of these species, there were 51 species of mollusce (43%), 36 of crustaceans (30%), 27 of polychaetes (23%). Molluscs were density-dominant faunal group with a mean density of 1,804 $ind./m^2$, comprising of 75% of the total density of the benthic animals. It was followed by polychaetes with 347 $ind./m^2$ (15% of the total density). Molluscs were biomass-dominant faunal group with a mean biomass of 147.51 $g/m^2$ (82% of the total biomass). The number of species, abundance and biomass showed increasing trends toward the lower intertidal stations from the higher stations. Major dominant species were Musculista senhousia (bivalve), Capitellidae spp. (polychaetes) with a density of 1,640 $ind./m^2$ and 179 $ind./m^2$ , respectively. The density of M. senhousia was more than 63% of the total density of benthic organism on the tidal area. Small gastropod Cerithideopsilla umumriensis was another dominant epifaunal species between st.1 and 2 with a mean density of 100 $ind./m^2$. Cluster analysis showed that the benthic community could be divided into three stational groups, that is, upper, middle and lower groups by the exposure duration.
