  • To find out ant fauna in the Mt. Chiak, collection tours were taken in three courses for two years. As a result, The ant fauna of Mt. Chiak were confirmed to be 45 species belonging to 23 genera under 4 subfamilies. Among them, ten species were new to Gangweon-province and Myrmica sp. 6 was new to Korea. Ants fauna of Gangweon-province at together became 74 species under 28 genera. In Ponerinae, ants fauna have become 5 species under 4 genera, in Myrmicinae, 20 species under 13 genera, in Dolichoderinae 1 species under 1 genera and in Formicinae 19 species under 5 genera.

  • The authors investigated the spider fauna of Mt. Yebongsan from May 1994 to Aug. 1996. In this paper, 265 species from 21 genera, and 28 families were identified and compared with those from islands geographical with differing i.e., Is. Paikryung-do, Is. Chin-do, and Is. Ulrung-do distribution and climate. Spiders from 45 palaearctic regions(3.69%), 13 holarctic regions(1.06%), 4 oriental regions(0.32%) and 5 cosmopolitans(0.41%) are identified. Various methods were used for collecting specimens during the period including pitfall, beating, sweeping and looking up-down.

  • The spider fauna of Namhai Island was investigated from 21 to 25 Aug 1998. As a result,81 species of 43 genera under 15 families were collected. Identified spiders are composed of 30.8% Palaearctic, 28.4% Palaearctic and Oriental, 6.1% Holarctic, 2.4% Oriental, and 3.7% Cosmopolitan species. Araneid, salticid and theridiid spiders appeared to be dominant among the spiders. Common species with Japan and China were 56(69.1%) AND 55 (67.1%) species, respectively.

  • This study investigated the composition and distribution of the soil microarthropods community in plantations of the Korean pine(Pinus Koraiensis SIEB. et ZUCC, the sudong area, Namyangju-gun, Korea) , which had been planted in different years. The soil samples intended to collect soil animals were taken monthly from June 1988 to July 1989. The composition of soil microarthropods community included Arachnida, Chilopoda, Insecta, Collembola, Diplopoda, Crustacea, and Symphyla. The Acarina were composed of 82.4% of Cryptostigmata, 8.0% of Mesostigmata, 7.9% of nymphs, and 1.7% of others. The Insecta included six orders including Hymenoptera(65.8%) and Diptera(13.9%). Population densities increased from when the plantations were first established until the planting were 25 years old, after which they declined. Population densities of the soil microarthropods were highest in July and lowest in January. The Collembola/Acarina ratio is 0.16 overall, and was highest in January and lowest in August.

  • To clarify the ants fauna in Chollabukdo, field survey was carried out for about 10 years from 1986 to 1995. As a result, 1,699 clonies were collected and identified. These clonies were composed of 76 species belonging to the 31 genera of 5 subfamilies. The list of ants in Chollabukdo was prepared with them involving a subfamily, 6 genera and 18 species newly recorded from Chollabukdo. In NSC analysis between areas, zones and clonies respectively, all 16 areas were continuous expect Bangchukdo. In block analysis of ant distribution. 28 species were found only in mountain-zone and 4 species in island-zone. Among 5 subfamilies distributied in Chollabukdo, Myrmicinae is the most abundant, but Cerapacinae is the oppisite. The Lasius of Formicinae is the most abundant genus among 31 genera investigated.

  • This paper deals with Korean Staphylinids fauna investigated in Korea by G. Lafer during 1994, 1995 and 1998. 38 species of rove beetles were recognized and among them, four species (Atheta weisei, Bolitobius setiger, Lesteva plagiata, and Sepedophilus germanus) are reported herein from Korea for the first time.

  • The spider fauna of DMZ(Demilitarized Zone) of Chulwon in Kangwon-do, Korea was investigated. As a result, the authors present a list of 54 species of 54 genera in 14 families (2 unidentified species newly known to Korea; Evarch sp(C)., Helicius sp. (A)) and revise Asianellus festivus of the unrecorded genus to be transferred from the genus Phlegra from Korea.

  • This research was carried out to investigate soil mictoarthropods fauna in Namsan and Kwangreung which were considered to receive different degreeds of environmental pressures. In basic environmental data, Namsan where under rather accelerated acidification by air contamination and acidic rain showed low pH, tardy decomposition and turnover rate. Population density of soil microarthropods was high in Kwangreung 17,169.8/\ulcorner\ulcorner(coniferous forests), 17,892.6/$\textrm{m}^2$(deciduous forests) than in Namsan, 12,143.8/$\textrm{m}^2$ (coniferous forests), 14,216$\textrm{m}^2$(deciduous forests). Biomass of soil microarthropods was 2,020.219mg/$\textrm{m}^2$ at coniferous forests and 4,270.172mg/$\textrm{m}^2$ at deciduous forests in Namsan, and 3,287.326mg/$\textrm{m}^2$ at coniferous forests and 4326.1mg/$\textrm{m}^2$ at deciduous forests in Kwangreung. Population density constantly showed high in spring, and seasonal fluctuations were correlated with seasonal precipitation. As far as vertical distribution is concerned, population density was concentrated in litter layer as 70% while 30% are in soil layer and also decreased with increasing depth.
