Abstract

헤베이 기름 유출에 따른 암반생태계 초기 영향 해석 Change in biomass was largely influenced by molluscs M. galloprovincialis and L. brevicula. Similar to the abundance, biomass also gradually increased after April 2008. Dominant species was not consistent whereas the most dominant species was always C. challengeri. In Gurepo, molluscs L. undulate, Barleeia angustata, and a cirriped C. challengeri were abundant. The most abundant C. challengeri was mostly found in the mid and low intertidal in high density. The abundance decreased until September 2008 and then increased after January 2009. Biomass of polychaetes and crustaceans continuously decreased for a year after the spill. was not consistent whereas the most dominant species was always C. challengeri.
