  • Two new Hydropsychidae (Insecta: Trichoptera) species from the Philippines are described. Hydropsyche philippinensis, n. sp., differs from other congeners in the structure of the phallic apparatus. Diplectrona lagunensis, n. sp., can be distinguished from other congeners by its distinct white band pattern in the forewings and by the structure of the phallus. Both new species were collected from a high mountain stream in the northern part of the Philippines. Paratype materials were barcoded to make the sequences readily available in the GenBank.

  • 이제 관광개발된 동굴과 미개발동굴 중 그 대표적인 몇 개동굴의 생물서식에 대한 변화에 대하여 조사기록에 의하여 분석하면 다음과 같다. 즉, 영월의 고저굴은 1975년 임문정 그리고 남궁 준 등의 조사기록에 나타나 있듯이 Gastropoda 2종, Cructacea 5종, Myriopoda 4종, Insecta 17종, 그리고 Mammalia 3종과 Arachnoida 10종등 총 41종을 발표하고있는데 관광개발된 후 3년이 지나 1978년 10월 현재에는 총 28종이 발견되었을 뿐인데 특히 게새우인 Crustacea가 1종, 곤충인 Insecta가 7종밖에 포착되지 않고 있어 많은 동굴생의 오손감소를 나타내고 있다.(중략)

  • Two problematic subgenera of Tomoceridae (Collembola, Insecta) were investigated for their phylogenetic relationships based on morphological characters and allozyme study from three relevant species. Different dendrograms were obtained obtained between morphological and allozyme studies. The morphological data did not give rise to any result distinctive enough to separate the two subgenera whereas the allozyme analysis produced a clear separation by the high genetic distance value. They were consistent, however, whether given rise to by using distance or cladistic methods and also whether character weighting or unweighting approaches employed in the morphological character analysis. As a consequence, it is strongly suggested that any prominent morphological trait might work as a good taxonomical character when supported by a strong genetic divergence as evidenced by allozyme analysis for instance.

  • Forest thinning brought the large variation to forest ecosystem including environment and animal. Our study was result of long-term monitoring for ground-dwelling arthropod communities after thinning in forest ecosystem. In this study, we conducted field study on plantation forest in Chuncheon, Korea in 2018, and compared with previous study data (2006 and 2008). We found that the effect of thinning was still existent 10 years later from thinning with difference of habitat environment(depth of ground organic matter, coverage rate of ground vegetation and canopy). And ground-dwelling arthropod communities showed changes of abundance and taxa at the study area and thinning conditions. Ground-dwelling arthropod communities in 2018 were dominant in the order of Diptera, Hymenoptera, Coleoptera (Insecta), Araneae (Arachnida) and Collembola (Collembola). Among the conditions of thinning, Araneae (Arachnida), Coleoptera and Hymenoptera (Insecta) showed amount of abundance in heavy thinning. And Collembola (Collembola) and Diptera (Insecta) were most common in area of light thinning. In 2018 ground-dwelling arthropod communities, abundance of Diptera and Coleoptera (Insecta) and Isopoda (Crustacea) were decreased although Hemiptera and Orthoptera (Insecta) were increased than 2008 arthropod communities. Arthropod communities in 2018 were more similar with those in 2008 (after thinning) than with those in 2006 (before thinning).
