초록

물리적인 교란(강우 발생)에 대한 동물플랑크톤의 피난처로서 수생식물의 역할을 평가하기 위해, 경상남도에 위치한 17개 습지의 수변부와 개방수역에서 환경 요인, 수생식물, 동물플랑크톤 등에 대해 조사하였다. 조사기간 동안, 총 51종의 동물플랑크톤이 출현하였으며, Polyarthra sp. 및 Diaphanosoma brachyurum 등의 부유성 성향을 가진 종이 주로 우점하였다. 습지의 수변부에서는 털물참새피, 마름, 붕어마름 등 10종 정도의 수생식물이 출현하였으며, 습지에 따라 종조성이나 생체량 등이 상이하였다. 이와 대조적으로, 개방수역에서는 수생식물이 거의 관찰되지 않았다. 대부분의 습지에서 개방수역보다 수변부에서 더 높은 동물플랑크톤 밀도가 관찰되었으며, 특히 1번, 8번, 9번, 10번, 11번, 16번 습지의 수변부에 서식하는 동물플랑크톤 군집은 강우 발생에 거의 영향을 받지 않거나 증가된 밀도를 보였다. 이들 습지의 수변식생대는 침수식물이 공통적으로 나타났으며, 다른 습지보다 상대적으로 다양한 수생식물종에 의해 구성된 특징을 가졌다. 침수식물이 수생식물 중 가장 복잡한 구조를 가지는 점을 감안하면, 침수식물의 존재는 식생대 내 서식처 복잡성에 크게 기여하며 강우와 같은 교란 요인에 저항하기 위한 피난처로서 높은 효율성을 가질 수 있다. 또한 침수식물은 서식 특성상 다양한 식물과 공존이 가능하며, 식생대 내 수생식물의 생체량을 증가시켜 더욱 복잡하게 만든다. 이러한 관점에서, 수생식물은 강우와 같은 교란 발생에 대한 생물다양성의 유지 및 증가에 크게 영향을 미치며, 우리나라와 같이 여름철에 강우가 집중되는 지역의 경우 플랑크톤 등 생물상에 대한 천이에 중요하게 고려되어야 할 것으로 사료된다.

In order to evaluate the role of macrophytes as refuge of zooplankton on physical distribution (i.e. summer rainfall), we investigated the environmental factors, macrophytes, and zooplankton in waterside zones (macrophytes zones) and open water zones of 17 wetlands from May and August, 2011. In this study, a total of 51 zooplankton species were identified, and Polyarthra sp. and Diaphanosoma brachyurum were found to be the most dominant species. Waterside area of each wetland were occupied by a total of 10 macrophyte species, species composition and biomass (dry weight) were different in the survey sites. Zooplankton was more abundant in waterside zone than open water zones lacking macrophytes (One-way ANOVA, df=2, F=27.1, P<0.05), in particular, waterside zone of 1, 8, 9, 10, and 11 wetland were supported by high zooplankton density after summer rainfall. This wetlands were developed by various macrophyte species than other wetland, and submerged plant commonly presented. Waterside zones with various macrophyte species provides complexity to the habitat structure, should be utilized as refuge to avoid disturbance such as summer rainfall. The results indicate that macrophytes are the key components to enhance bio-diversity include zooplankton, and the inclusion of diverse plant species in wetland construction or restoration schemes will result in ecologically healthy food webs.
