  • The Kosudong-gul Cave at kosu-ri, Daegang-myon, Danyang-gun, Chung Chong Bug-do, Province was surveryed by this author on the 3rd of Nov. 1973, 6th of Jan. 1974, 30th of Aug. and 13th of Sept. 1975 through over several times field trips. Yoechon-gul Cave at Yoechon-ri, Gagok-myon, Danyang-gun, Chung Chong Bug-do, Province was surveyed by this author on the 30th of August, 1975. The enviromental factors of both caves checked the siftations for air temperature, water temperature, moisture and pH, as well as the faunae f both caves and ecollogically studieel them. Kosudong-gul Cave (1) The environmental factors checked was the same as table 1. (2) The fauna is 5 classes and 18 species and they classified as Troglobite......2 species-11.1%, troglophile.....5 species-27.7%, and trogloxene....11 species.-61.2%. Yochon-gul Cave (1)The environmental factor Checked was the same as table 2. (2) The fauna is 5 classes and 8 species and they classified as troglobite......1 species-11.1%, troglobite....4 species-44.4% and trogloxene.....4 species-44.4%.

  • The complete mitochondrial genome of a troglobite millipede Antrokoreana gracilipes (Verhoeff, 1938) (Dipolopoda, Juliformia, Julida) was sequenced and characterized. The genome (14,747 bp) contains 37 genes (2 ribosomal RNA genes, 22 transfer RNA genes and 13 protein-encoding genes) and two large non-coding regions (225 bp and 31 bp), as previously reported for two diplopods, Narceus annularus (order Spirobolida) and Thyropygus sp. (order Spirostreptida). The A + T content of the genome is 62.1%, and four tRNAs ($tRNA^{Ser(AGN)}$, $tRNA^{Cys}$, $tRNA^{Ile}$ and $tRNA^{Met}$) have unusual and unstable secondary structures. Whereas Narceus and Thyropygus have identical gene arrangements, the $tRNA^{Thr}$ and $tRNA^{Trp}$ of Antrokoreana differ from them in their orientations and/or positions. This suggests that the Spirobolida and Spirostreptida are more closely related to each other than to the Dipolopoda. Three scenarios are proposed to account for the unique gene arrangement of Antrokoreana. The data also imply that the Duplication and Nonrandom Loss (DNL) model is applicable to the order Julida. Bayesian inference (BI) and maximum likelihood (ML) analyses using amino acid sequences deduced from the 12 mitochondrial protein-encoding genes (excluding ATP8) support the view that the three juliformian members are monophyletic (BI 100%; ML 100%), that Thyropygus (Spirostreptida) and Narceus (Spirobolida) are clustered together (BI 100%; ML 83%), and that Antrokoreana (Julida) is a sister of the two. However, due to conflict with previous reports using cladistic approaches based on morphological characteristics, further studies are needed to confirm the close relationship between Spirostreptida and Spirobolida.

  • 치악산에 위치한 원주 신림면 성남2리에 있는 회옥굴의 동굴생물 종의 분포와 생태적 특성을 알기위해 2004년 11월부터 2005년 6월까지 현장조사 연구를 통해 동굴생물의 보전과 관리를 위한 자료를 얻고자 본 연구를 시행하였으며, 다음과 같은 결과를 얻었다. 조사된 회옥굴의 동굴생물 분포는 8강 18목 28과 34종이었으며, 곤충강이 7목 11과 14종(41.2%)이었다. 회옥굴 내의 서식 생물을 생태적 특성에 따라 구분하면 진동굴성은 8종(23.5%), 호동굴성은 7종(20.6%), 외래성이 19종(55.9%)으로 나타났으며, 동굴에의 적응율은 44%로 외래성 생물의 분포가 높은 것으로 나타났다.

  • (1) The author surveyed the environmental factors and the fauna of Sung-Yoo Cave(360m in length) from November 29 to December 2, 1961. (2) Air temperature, water temperature, moisture, water depth, water gravity, oxygen concentration carbon dioxide concentration and pH in water of the cave were studied as enveronmental factors. The results are shown in the Table 1~7 and Fig.3. (3) Four species of troglobite (22.2%). seven of troglophile(38.9%). four of troglozene(22.2%). and three of parasite constitute the terrestrial fauna of Sung-yoo Cave. In the other hand, all of the aquatic fauna(4 species of fish) of the cave were troglozene. (5) None of the species of animals listed in this paper has ever been recorded in Korea.

  • 평창군 미탄면 기화리에 소재한 쌍굴의 동물종 구성과 생태적 개체군 변동을 파악하기 위하여 2005년 1월부터 2005년 6월까지 6개 조사지로 구분하여 관찰, 채집, 조사한 결과 전체 동물종은 총 4강 11목 16과 19종이었고, 총 조사개체수 중 알락꼽등이가 66.6%, 등줄굴노래기가 22.4%로 전체의 확인 개체군 중 우점종으로 확인되었다. 조사된 생물 중 생태적 특성에 의한 진동굴성이 5.3%, 호동굴성이 21.1%, 그리고 외래성이 73.7%로 외래성이 가장 많은 종을 차지하였다. 포유강에서는 관박쥐와 물윗수염박쥐의 2종이 확인되었으며, 그 중 관박쥐가 58.9%를 차지하고 있어 우점종으로 확인되었다. 외래성인 담흑물결자나방은 겨울철인 1, 2월에 가장 많은 개체수가 확인되었다. 진동굴성인 등줄굴노래기는 6월에 503개체가 관찰되었고 호동굴성인 알락꼽등이는 4, 5월을 정점으로 봄철에 많은 개체수가 나타났으나, 6월에는 개체수가 급격히 줄었다.
