“…The flowering period was affected not only by water temperature, but also latitude and genetic variation (Phillips et al, 1983). Lee et al (2005b) in a study in Ulpo, Korea reported that the reproductive shoots of Z. caespitosa observed from February (10℃) to May…”

The variations of morphological features, density and biomass of vegetative shoots and characteristics of reproductive shoots of Zostera caespitosa were examined in Tongyeong, Korea. Morphological features such as leaf length, width and sheath length of Z. caespitosa showed significant seasonal variation (p < 0.001). The highest aboveground value was recorded in late spring to summer and the lowest value in winter. Density and biomass also showed seasonal variations. Annual average shoot density and biomass of Z. caespitosa were recorded as 1,223.4 leaf m -2 and 5,956.9 g w.w.m -2 , respectively, and had the highest value in June and lowest values in November and January. Reproductive shoots were observed from April (13℃) to June (21℃). Pistils erected outside sheath, anther dehiscing and small embryos were found in April. Mature fruit and released seeds were found in May and June. These results suggest that this species had a high growth rate in late spring and early summer (15℃-20℃). Reproductive shoots of Z. caespitosa may initially appear at about 10℃ in spring and seed have been released at about 20℃ in fall.

“…There have been few studies on Z. caespitosa in Korea (Lee et al, 2002(Lee et al, , 2005b(Lee et al, , 2005c. In this study, to clarify the phenology of Z. caespitosa, we investigated the variation of morphological features, density, biomass and characteristics of reproductive shoots of Z. caespitosa in Tongyeong, Korea.…”

“…광양만 일대에 자생하는 해초지는 승봉도와 같은 거머리말로 이루어진 곳으로 저조시 수심 약 1m에서 생육하여 3m 까지 분포하고 있으며, 남해안의 특성상 조석 간만차가 적어서 해초지가 물 밖으로 노출되지 않는다 (Jeong et al, 2004;Yoon, 2006). 그러나 승봉도 연안의 해초지의 경우, 애기거머리말(Z. japonica)은 조 간대의 중부에서 하부까지, 거머리말(Z. marina)은 조간대 하부와 간조시 수심 1m 내외의 조하대에 패치로 분포하며 해초가 물 밖으로 노출되는데, 이는 조석 간만차가 큰 서해안의 특성을 반영한 결 과로 보인다 (Lee et al, 2005) (Go and Cho, 1997;Hong et al, 2004;Huh, 1986;Huh andAn, 1997, 1998;Jeong et al, 2004;Kong, 1981Kong, , 1982Yoon, 2006;Yun et al, 1997Yun et al, , 2002 서해 연안 도서 해초지에 서식하는 생물종에 대한 연구는 남해안 해초지 연구에 비하면 크게 관심 을 받지 못하고 있다. 그러나 광양만 해초지에서 보고된 저서무척추생물종이 391종임을 볼 때 본 연 구지역인 승봉도를 포함한 서해 연안 도서 해초지에 서식하는 생물종도 기존에 보고된 종보다 더 많 은 종이 있을 것으로 추정된다 (Go and Cho, 1997;Hong et al, 2004;Huh, 1986;Huh andAn, 1997, 1998;Jeong et al, 2004;Kong, 1981Kong, , 1982Yoon, 2006;Yun et al, 1997Yun et al, , 2002 (Go and Cho, 1997;Hong et al, 2004;Huh, 1986;Huh andAn, 1997, 1998;Jeong et al, 2004;Kong, 1981Kong, , 1982Yoon, 2006;Yun et al, 1997Yun et al, , 2002.…”

To elucidate the species diversity and distribution of benthic invertebrates at intertidal zones of Eilrae Beach and Buchae Stone in Seungbongdo Island, sampling was performed at October 12∼13, 2007 and January 24∼25, 2008. In this study, 105 species out of 10 phyla were revealed. Together with previous reports, 193 species have been reported from Seungbongdo Island up to now. Among them, 63 species were newly reported from this study.

In this study, crude extract of the seagrass Zostera japonica, and its solvent-partitioned fractions were evaluated for their antioxidant activity. The crude extract was successively fractionated into n-hexane, 85% aqueous methanol (85% aq.MeOH), n-butanol (n-BuOH), and water fractions by liquid-liquid partition. These include DPPH radical scavenging, hydroxyl radical scavenging in HT-1080 cells, peroxynitrite scavenging, and protective effect on DNA damage caused by hydroxyl radicals generated. In all assays, except for DPPH radical, 85% aq.MeOH and n-BuOH fraction showed the strong antioxidant activity. These results suggest that Z. japonica may be used as a potential source of natural antioxidants for the development of cosmetic product or functional food in the future.
