초록
야광충 Noctiluca scintillans의 시공간적 변동과 생태학적 특성을 이해하기 위해서 그들의 개체수 밀도와 환경인자를 광양만 20개 정점과 진해만 23개 정점에서2010년 춘계, 하계, 추계, 동계의 계절 조사를 수행하였다. 야광충 N. scintillans는 광양만과 진해만에서 15~27℃ 수온 범위의 춘계와 하계에 높은 밀도가 유지된 반면, 동계와 추계는 그들의 개체수가 감소하였다. 두 해역에서 야광충의 개체수는 수온과 유의한 상관관계가 성립되었고, 이는 수온 증가와 더불어 N. scintillans의 증식이 활발해 진다는 것을 의미한다. 특히, 두 해역에서 4계절 모두 야광충의 출현은 확인하였으나, 저온(<⁄4℃)과저염(<⁄12 psu)에서 그들 개체를 관찰할 수 없었다. 먹이생물의 지표가 되는 Chl.a 농도와 야광충의 개체수는유의한 상관관계를 확인할 수 없었으나, 두 해역에서Chl.a 농도가 현저하게 높았든 춘계와 하계에 야광충 개체수밀도가 높게 나타났다. 결과적으로 식물플랑크톤의현존량은 야광충 N. scintillans의 개체수 증감을 제어하는 중요한 인자로 판단되었다.
Abstract
To understand the spatio-temporal fluctuations and ecological characteristics of heterotrophic dinoflagellate Noctiluca scintillans, we investigated their population densities and environmental factors during four seasons at 20 stations of Gwangyang Bay and at 23 stations of Jinhae Bay in 2010. N. scintillans was seasonally abundant during spring and summer, with temperature ranging 15 to 27℃ in the both bays, whereas the density reduced in fall and winter. The populations of N. scintillans at each station in both bays showed a significantly positive relationship with water temperature, indicating that relatively high water temperature within its optimum temperature stimulates the growth of N. scintillans population. In particular, low water temperature (<⁄4℃) and salinity (<⁄12 psu) led to disappear of N. scintillans population, although they were observed at all season in both bays. Spatio-temporal variations of Chl.a concentration was not significantly correlated with N. scintillans population densities. However, the Noctiluca abundances were also high during spring and summer season when relatively high Chl.a concentration was observed in both bays. This result suggests that standing crops of phytoplankton may be one of important contributing factors to enhance the abundance of N. scintillans.
