In this study, we investigated carabid beetles residing in the wetlands to understand their ecological adaptation and strategy selection associated with restricted resources and habitat limitation. The species richness, abundance, seasonal activity, and spatial distribution of the carabid beetles between the Mujechi Wetlands (wetland sites) and Mt. Jeongjok (mountain sites) have been compared. A total of 1,733 individual beetles from 30 species were collected and classified at the studied sites. The wetland sites were identified as having lower species richness and abundance for carabid beetles when compared with the adjacent mountain sites, whereas these beetles were observed to be dominant in the wetland sites than in the adjacent mountain sites. Calosoma inquisitor cyanescens, Carabus sternbergi sternbergi, and Carabus jankowskii jankowskii species were dominant in both the wetland and mountain sites. These species showed significantly different seasonal activity patterns in the wetland sites relative to the mountain sites. Although the three listed carabid species were observed to be widely distributed throughout the wetland sites, they still showed preference for drier sites, which clearly shows a distinction in their habitats. The results of the spatial-temporal distribution of carabid beetles in the wetland sites reflect their special strategies regarding space and time partitioning for maintaining their population. The distribution patterns of carabid beetles in the wetland sites also showed the desiccation gradient and environmental changes prevalent in wetlands. Ecological surveys, which use carabid beetles in the wetlands, can then be performed when restoring wetlands and for establishing management practices for improving the habitat quality.

Change of carabid beelte (Coleoptera, Carabidae) diversity and population structures in Woopo Wetlands (Changneung-Gun, Gyeungsangnam-Do, S. Korea) were investigated after flooding events. During the investigation period, 11 species belonging to five genera were identified. Dolichus halensis halensis(Schaller), Chlaenius (Ch.) pallipes Gebler, Ch. (Ilaenchus) naeviger Morawitz, and Pheropsophus (Stenaptinus) jessoensis Morawitz were the predominant species in Woopo Wetlands. Floods occurred twice, August and September in 2004. After the flooding events, species diversity decreased and species assemblage structures changed dramatically. Changes of the diversity and species assemblage structures were more evident in August then in September, because water level was much higher and inundation period was longer than September. A non-linear patterning algorithm of the Self-Organizing Map (SOM) was applied to discover the relationship between flooding events and carabid beetles community dynamics. Although abundance of the majority species decreased after the flooding events, that of the predominant species increased. Further detailed studies on species distribution and emigration patterns will likely bring a new insight in understanding of the adaptation mechanism of carabid beetles in wetlands.

습지의 서식지 특성 및 환경 지표종을 찾기 위해 부산과 경남에 위치한 습지 유형이 다른 하천습지, 산지습지, 하구습지에서 딱정벌레류를 조사하였다. 조사결과 딱정벌레과, 먼지벌레과, 폭탄먼지벌레과에 속한 22속 28종이 채집되었고, 종 다양성은 하천습지(우포늪, 화포늪), 산지늪(재약산늪), 하구습지(낙동강하구) 순으로 나타났다. 딱정벌레류의 종조성은 각 습지에서 독립적으로 나타났는데(${\chi}^2=1716.8$, P<0.01), 하천습지와 산지늪이 가장 다른 종조성을 보였다. 지표종 분석을 통해 각 유형의 습지를 대표하는 $2{\sim}6$종의 딱정벌레류를 지표종으로 선출하였는데, 지표종들은 토성과 토양습도, 인위적 환경변화에 대해 민감하게 반응하여 습지환경변화를 모니터링할 수 있는 것으로 보인다. 추후 생활사나 먹이특성 등딱정벌레류의 각종별로 자세한생태적 특성이 연구되면 지표종으로 딱정벌레류를 일반화하여 여러 서식지에서 활용할 수 있을 것으로 보인다.

초식, 포식, 분해 등 생태학적 서비스를 제공하는 지표 배회성 절지동물은 사과원의 중요한 구성 요소이며, 이들의 군집에 영향을 미치는 잡초는 유기재배와 관행재배 사과원에서 다르게 관리된다. 잡초 관리와 관련된 과수원 관리가 지표 배회성 절지동물의 풍부도와 다양도에 미치는 영향을 평가하기 위해 3년간 연구를 수행하였다. 대부분의 절지동물은 상위분류군과 섭식 기능군으로 분류하였으며, 딱정벌레류는 종 수준으로 분류하였다. 지표 배회성 절지동물의 주요 우점군은 딱정벌레목으로 나타났다. 초식자와 포식자의 풍부도는 유기재배 사과원에서 높은 결과를 보였으며, 딱정벌레류의 풍부도와 다양도 또한 관행재배 과원보다 유기재배 사과원에서 높은 결과를 보였다. 거미목, 딱정벌레목 또는 딱정벌레류의 풍부도는 잡초 관리 빈도와 음의 상관관계를 보였다. 지표 배회성 절지동물은 농업 시스템보다 잡초 관리에 영향을 더 많이 받는 것으로 나타났다.

Carabid beetle community changes in paddy fields, abandoned paddy fields, and mountains were investigated to understand differences in species diversity and composition of different habitat types in small agricultural landscapes in South Korea. A total of 2,938 individuals from 37 species were identified and classified from the studied habitats. Diversity in the mountains was higher than that in abandoned paddy fields. As the number of years since abandonment increased, the diversity and stability of the carabid beetle community also increased. Abandoned paddy fields in some paddy field areas and adjoining mountainous areas, left with preconditions for management and control, have provided the opportunity to improve the diversity and habitat of small agricultural landscapes. Species composition changed continuously from the paddy fields to the mountains, in accordance with individual species habitat preferences. Abandoned paddy fields in small agricultural landscapes are believed to play an important role as transitional buffer zones between paddy fields and the adjacent mountainous areas.

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.

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.
