본 연구는 농업 생태계의 생물다양성 보전에 있어 서식처 기반의 보전 전략을 수립하는데 있어 기본 정보를 제공하기 위해 수행되었다. 연구는 경기도 화성시 팔탄면에 위치한 환경압박이 서로 다른 3개 조사지(농경지와 야산으로 이루어진 조사지 1, 공장이 많이 위치하는 조사지 2, 거주지역이 많이 차지하는 조사지 3에서 4개의 토지이용(야산, 밭둑, 논둑, 하천변)별로 2000년 11월부터 2002년 11월까지 39회의 딱정벌레 군집 조사를 통해 이루어졌다. 본 연구의 주요 결과로 서 딱정벌레 군집 조성, 우점종 그리고 군집 패턴이 토지이용에 따라 다르게 나타났으며, 유사도는 조사지 2와 3의 논둑에서 가장 높게 나타났고, 조사지 2의 야산과 조사지 3의 하천변간의 유사도가 가장 낮았다. 또한 도로에 의해 파편화된 서식처간의 유사도가 서로 다른 서식처 및 조사지간의 유사도보다 낮게 나타났다. 이를 통해 생물다양성 보전과 네트워크 측면에서 농경지 토지이용은 각각이 중요한 역할을 수행하고 있음을 알 수 있다. 본 연구는 국내 농촌경관에서의 서식처별 딱정벌레 군집분석을 통하여 생물다양성 보전에 대한 기초 자료를 제공한다는 점에서 가치를 평가할 수 있다.

Herein, 24 species of the carabid beetles are reported from South Korea. Of these,5 species, Aephnidius adelioides(Mac Leay, 1825), Badisrer(Baudia) nakayamai Morita, 1992, Bembidion(Trichoplataphus) eurygonum(Bates, 1883), Cillenus (Novicillenus) aestuarii ($U\'{e}no$ & Habu, 1955), Cillenus(Desarmarocillenus) yokohamae(Bates, 1883), are listed for the first time from the Korean Peninsula. A new junior subjective synonym is established: Oodes integer Semenov, 1889=Oodes helopioides tokyoensis Habu, 1956. Syn. Nov.

The Scarites aterrimus (Coleoptera: Carabidae), is one of the carabid beetles dwelling exclusively on coastal sandy dunes. Habitat deterioration and equivalent activity have greatly concerned population declines in several species dwelling on the coastal sandy dunes. As a first step to establish long-term conservation strategy, we investigated the nation-wide magnitude and nature of genetic diversity of the species. As a first step, we sequenced a portion of mitochondrial COI gene, corresponding to "DNA Barcode" region (658 bp) from a total of 24 S. aterrimus individuals collected over nine sandy dunes belonging to four Korean provinces. The sequence analysis evidenced moderate to low magnitude of sequence diversity compared with other insect species distributed in Korean peninsula (0.152% to 0.912%). The presence of closely related haplotypes and relatively high gene flow estimate collectively suggest that there had been no historical barriers that bolster genetic subdivision. Population decline was postulated on the basis of several missing haplotypes that are well found in the species with a large population size. This interpretation is consistent with field observation of small population size in the coastal sandy dune habitats. The highest genetic diversity estimates were found in the coastal sand dune population of Seogwipo, Jeju Island, justifying a prior attention to the population, in order to sustain overall genetic diversity of the species. Further scrutinized study might be required for further robust conclusion.

The Scarites aterrimus (Coleoptera: Carabidae) dwells exclusively on coastal sandy dunes. Previously, we investigated the nation-wide magnitude and nature of genetic diversity of the species using mitochondrial COI gene and found moderate to low magnitude of sequence diversity, the presence of closely related haplotypes, and relatively high gene flow estimate. Based on these observations we concluded that the species had no historical barriers that bolster genetic subdivision and possible population decline. In this study, we additionally sequenced mitochondrial COII gene from 23 individuals collected from 9 Korean localities to confirm previous findings. Sequencing of 688 bp COII gene provided 5 haplotypes ranging in sequence divergence from 0.145% to 0.291% (1 ~ 2 bp), further confirming low sequence divergence of the species. Gene flow estimates and genetic diversity estimates also support the previous findings that there had been no historical barriers that bolster genetic subdivision.

Sensilla on the aedeagi of 4 species under the genus Damaster were studied using scanning electron microscopy. A total of 37 types of sensilla were distinguished from the aedeagi of the species examined. The number of sensilla types was the largest in D. (Coptolabrus) smaragdinus branickii, 25, and 23 in D. (C.) jankowskii jankowskii. In D. (Acoptolabrus) gehinii gehinii and D. (Damaster) blaptoides blaptoides, 22 and 21 types of sensilla were found, respectively. External morphology and distribution patterns of sensilla were also described. The phylogenetic relationships among the species were discussed based on their distribution patterns.

Understanding how future climate conditions will be impact on the biodiversity and species composition is important, because biodiversity becomes more important in environment assessment. To understand the biological changes including diversity and species composition over time (temporal variation within a year), the species diversity and composition of ground beetles were investigated in two well-preserved areas in the Sobaeksan National Park using pitfall traps. In addition, relationships between ground beetles and environmental variables were studied by considering temporal variation. We collected 2,146 ground beetle specimens representing 45 species, and individual-based rarefaction curves indicated that similar species richness was found between Geumseon Valley (GV) and Namcheon Valley (NV). The Bray-Curtis matrix comparisons between study sites were characterized by similar ground beetles sample heterogeneity, while temporal variations in abundance, species richness, and ${\beta}-diversity$ of ground beetles showed rather difference over time according to location of study sites. In GV site, minimum temperature was selected as the best predictor for abundance, species richness, and ${\beta}-diversity$ of ground beetles, while those relationships in NV site were more complicated. In conclusion, our study suggests that understanding the different response of ground beetles to climatic variables related to local habitat conditions is important to predict the effect of climate change on biological communities.

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. 반면, 방품림에서는 14종이 채집되었고, 둥근칠납작먼지벌레(1,630개체), 윤납작먼지벌레(130개체) 및 붉은칠납작먼지벌레(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.
