독특한 경관특성과 높은 보존적 가치에도 불구하고, 사구와 관련된 곤충 다양성 연구는 매우 부족한 편이다. 따라서 본 연구에서는 태안해안국립공원에서 주로 관찰되는 사구와 방풍림(해송)에서 서식하는 지표성 딱정벌레류 군집 구조에 대한 비교 연구를 수행하였다. 2014년 6월 중순부터 10월 중순까지 함정트랩을 이용하여 방풍림 5개 지점과 사구 3개 지점을 조사하였다. 조사 결과, 총 2,335개체의 지표성 딱정벌레류를 채집하였으며, 이들은 15속 30종으로 동정되었다. 사구에서는 24종이 채집되었는데, 둥근칠납작먼지벌레(158개체)와 등빨간먼지벌레(153개체)가 우점하였다. 반 면, 방품림에서는 14종이 채집되었고, 둥근칠납작먼지벌레(1,630개체), 윤납작먼지벌레(130개체) 및 붉은칠납작먼지벌 레(42개체)가 우점하였다. 방풍림과 사구의 지표성 딱정벌레류 종 구성의 유사도는 27.4%로 낮았다. 본 연구 결과는 태안해안국립공원에서 발견되는 사구 지형이 방풍림과 비교해서 다른 곤충 군집을 보유하고 있음을 보여주고 있으며, 이는 향후 곤충 보전을 위한 중요한 정보가 될 것이다.

Community structures and species composition in benthic crustacean around Oryukdo of Busan was investigated using a SCUBA diving in 2011. A total 115 species, 51 families, and 4 taxa were collected during the sampling periods. Species were included 52 species in amphipoda, 49 in decapoda, 8 in isopoda and 6 in thoracica. On cluster analysis, the benthic crustacea community was classified into three groups based on the species composition: group A occurred in spring, group B in autumn and winter and group C in summer. Species composition in benthic crustacean corresponded with the water temperature.

This study was conducted to examine the community structure of ground beetles between coniferous and deciduous forest in rural landscapes along latitudinal gradient, such as Miryang-si, Yeongdong-gun, Icheon-si, and Cheolwon-gun from April to October in 2009. A total of 19 species belonging to 15 genera of 9 subfamilies were identified from 6,253 collected ground beetles. Between forest stands, 14 species belonging to 10 genera of 7 subfamilies were identified from 2,874 ground beetles in coniferous forests and 14 species belonging to 11 genera of 7 subfamilies were identified from 3,379 ground beetles in deciduous forests. Dominant species from 4 regions were Synuchus nitidus (59.4% of total) and Synuchus cyloderus (28.5%) respectively. Analysis of similarity (ANOSIM) showed no difference between forest stands, but it was significantly different among regions. Non-metric multidimensional scaling showed that 8 study sites were divergence to 2 major groups between Miryang-si and the others. Overall, community structure of ground beetles showed no difference between forest stands. In conclusion, rural forests is being discussed about important role in biodiversity conservation such as refuge from human activity, and thus, studies on the community structure of ground beetles in the rural forests will be important to manage the biodiversity in agricultural landscapes, because ground beetles are well known for general predator groups in the ecosystems.
