Global environmental changes have the capacity to make dramatic alterations to floral and faunal composition, and elucidation of the mechanism is important for predicting its outcomes. Studies on global climate change have traditionally focused on statistical summaries within relatively wide scales of spatial and temporal changes, and less attention has been paid to variability in microclimates across spatial and temporal scales. Microclimate is a suite of climatic conditions measured in local areas near the earth's surface. Environmental variables in microclimatic scale can be critical for the ecology of organisms inhabiting there. Here we examine the effect of spatial and temporal changes in microclimates on those of carabid beetle communities in Hyangnobong, Korea. We found that climatic variables and the patterns of annual changes in carabid beetle communities differed among sites even within the single mountain system. Our results indicate the importance of temporal survey of communities at local scales, which is expected to reveal an additional fraction of variation in communities and underlying processes that has been overlooked in studies of global community patterns and changes.

In the current study, several carabid beetle species were proposed as potential biological indicators for different habitat types (levee, upland dike, hillock, and streamside) of agricultural landscapes focusing on agrobiont species. Synuchus arcuaticollis and Synuchus orbicollis were found in all habitat types, indicating that they are general species for all habitat types. Harpalus eous and Synuchus cycloderus are potential bioindicator species for the paddy levee and hillock habitats, respectively. Amara pseudosimplicidens, Anisodactylus punctatipennis, and Chlaenius ocreatus, which occurred widely, and Bembidion morawitzi, which occurred only in the streamside habitat, are potential bioindicators for the streamside habitat.

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.

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.

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.

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.

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.

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.
