This study was conducted to provide basic information for development of habitat-based conservation strategies of biological diversity in agricultural ecosystem. The carabid beetle assemblages were examined at four kinds of habitats(levee, dike, forest patch remnants and streamside) from three differently stressed areas located in Paltan-myun, Hwaseong city, Korea: agricultural and forest area(site 1), industrial area(site 2), and residential area(site 3). Pitfall trap samplings were carried out 39 times from November 2000 to November 2002. Our study's findings were that the composition of carabid beetle fauna, dominance species, and pattern of carabid beetle assemblage were different among the habitats. The similarity index was highest between two levees in site 2 and 3, and lowest between hillock in site 2 and streamside in site 3, and that among habitats fragmented by road with high traffic was lower than that among any other habitat types. So, we could know that agricultural land use respectively do an important role in diversity conservation and networking. These findings will be used to establish the land use and management plans in the aspects of conservation of biodiversity.

The ground beetles or carabids are essentially predaceous feeding on a wide variety of insects including forest pests, slugs and land snails containing those injurious to livestock or veterinary, thus many are predominantly beneficial and serve as natural enemies. In the present investigation, some morphometric multivariate analysis were done for 9 different populations in 5 subspecies of D. (C.) jankowskii, which are one of the most common ground beetles in Korea As the results, when the comparison was conducted between intraspecific groups regardless of subspecies in external morphological characters, the average group membership revealed 97.46% correct assignment For intersubspecific comparisons alone 96.3% were correctly classified. Between the groups of ssp. jankowskii an average of 100% individuals were classified in their known group. Thus the predict group membership was highly significant(P<0.001), exceeding so-called 'the 75% rule'. Whereas, the average group membership using the male genitalic characters represented less than the 75% assignment, except only in ssp. quelpartianus (85.6%). The population from Is. Chindo were described here as a new subspecies for qualitative as well as the resultant quantitative differences. Therefore, a total of 7 subspecies are represented in Korea. Among them, the nominate subspecies, ssp. jankowskii(sensu lato), revealed distinct intrasubspecific differences between different geographic populations. These differences can be as notable as intersubspecific variation which need substantial revision of the previous intuitional concepts on the infraspecific level.

This study was carried out to offer forensic entomological evidence to estimate the post mortem interval (PMI) based on the arthropod succession in pig carrions and carrion decomposition patterns varying with the exposed extent of the carrions. Four carrions, exposed, wrapped, covered or shaded, were placed in an open grassland near the Nakdong-river in Busan in August, 2010. It was found that the first visiting insect was Chrysomyia megacephala among a total of 20 species of 15 families belonging to 7 orders of Insecta, and that four species were useful indicators of the decomposition stage of the carrion: C. megacephala for I~V stages; a species of Sepsidae, Creophilus maxillosus and a species of Carabidae for III~V stages. It was also found that the more the exposed extent of exposure of carrions, the higher the rate of decomposition of carrions, i. e. the time for decomposition of carrions were 7days for the exposed carrion, 10days for the covered one, 13days for the shaded one, and 15days for the wrapped one. This result seems to be related to the differences in the weight loss of carrions caused by strong rains during the research period and by the accessibility of insects to the carrions; both are strongly affected by the exposed extent of the carrions. Accordingly, it was suggested that the exposed extent of the carrions must be taken into consideration to estimate the PMI.

Ground beetle fauna of Mt. Bangtaesan in Inje-gun, Gangwon-do was investigated from June to October in 2010. Ground beetles were collected by pitfall trapping. A total of 34 species of 18 genera belonging to 7 families were identified from 1,041 collected ground beetles. Species richness was high in Pterostichinae (15 species, 44.1%), Carabinae (7 species, 20.6%), Harpalinae (4 species, 11.8%), Nebriinae (3 species, 8.8%) and others (5 species, 14.7%). Dominant species were Synuchus spp. (260 individuals, 25.0%), Aulonocarabus semiopacus (218 individuals, 20.9%), and Pterostichus audax (205 individuals, 19.7%) in order. Korean endemic species were collected 564 individuals belonging to 10 species. By principal component analysis (PCA), species distribution and abundance of ground beetles were different depending on habitat characteristics of vegetation, surrounding environment and feeding habitat. Carabinae and Pterostichinae which live in the forest were preferred in hardwoods and coniferous in the Bangtansan Natural Recreation Forest, while Callistinae and Harpalinae were collected in forest adjacent to grasslands. Overall, differences of habitat environments within forest are important factors associated with distribution of ground beetles. This result will provide useful informations with establishment of conservation program and long-term monitoring against environmental change within mountain by using ground beetles.

There are few available studies for insect diversity in relation to coastal dune despite the unique landscape features and high conservation value. Therefore, this study compared ground beetle assemblages inhabiting between windbreak forests and sand dunes in the Taeanhaean National Park. It investigated five windbreak forests and three coastal dunes using pitfall traps from middle of June to middle of October in 2014. A total of 2,335 ground beetles belonging to 30 species of 15 genera were collected. Synuchus arcuarticollis (158 individuals) and Dolichus halensis halensis (153 individuals) were dominant of 25 specifies collected from sand dunes while Synuchus arcuarticollis (1,630 individuals), Synuchus nitidus (130 individuals), and Synuchus cycloderus (42 individuals) were dominant of 14 species collected from windbreak forests. The similarity of ground beetles compositions in sand dunes and windbreak forests was significantly low at 27.4%. The results of this study showed that sand dune geographical features found in the Taeanhaean National Park had different insect assemblages from windbreak forests. It will be the useful information for conservation of insects in the future.

Korea has put in significant efforts to increase the number of wildlife crossings between fragmented habitats to prevent loss of biodiversity and to encourage the habitat connectivity in Korea. However, there is a lack of biological data on the effect of vegetation structure in these wildlife crossings and guidelines for design and management of wildlife crossing structures in Korea. Therefore, we selected ground beetle assemblages as model organisms to compare the effect of vegetation structure in wildlife crossings, i.e. bare ground- and shrub-type corridors, in agro-forested landscapes. For this study, 4,207 ground beetles belonging to 33 species were collected through pitfall trapping along the northern forest-corridor-southern forest transects from late April to early September in 2015. Dominant species, abundance, and species richness of ground beetles were significantly higher in the shrub-type corridors than the bare ground-type corridors. Also, the species composition of bare ground-type corridor was significantly different compared to the other habitats such as shrub-type corridor and forests. Similarly, environmental variables were also influenced by vegetation management regimes or trap locations. Collectively, our study clearly indicates that the movement of forest associated ground beetles between forest patches can increase as the vegetation in wildlife crossings becomes complex. Although further studies are needed to verify this, there are indications that the current wildlife crossings that comply with the guidelines may be unfriendly to the movement of ground dwelling arthropods as well as ground beetles. To enhance the ecological function of wildlife crossings, the guidelines need to be rectified as follows: 1) Shrubs or trees should be planted along the corridor verges to provide refuge or movement paths for small mammals and ground dwelling arthropods, and 2) Open spaces should be provided in the middle of the corridors to be used as a path for the movement of large mammals.
