  • 에콰로르의 수도인 키도와 갈라파고스에서 2000년 8월 1일부터 18일까지 거미상을 조사한 결과 총 562개체를 채집하였으며, 그 중 22과 48속 50종을 동정하여 보고하고자 한다. 이를 통해 키토와 갈라파고스 제도에는 배회성 보다 정주성 거미류가 더 우세한 것으로 확인되었으며, Gasteracantha cancriformis (Linnaeus 1758)가 우점종으로 나타났다. 이에 Gasteracantha cancriformis를 재기재하여 보고하고자 한다.

  • Penguins are one of the key constituent organisms in the Antarctic ecosystem. A total of 18 species of penguins occur only in the southern hemisphere from the Galapagos Archipelago to southern area off Australia and New Zealand, South Africa, South America, and the islands scattered in the Southern Ocean to the coast along the Antarctic Continent. In the Antarctic Treaty area, there are only 5 species of penguins such as Emperor (Aptenodytes forsteri), Gentoo (Pygoscelis papua ellsworthi), Adelie (P. adeliae), Chinstrap (p. antarctica), and Macaroni (Eudyptes chrysolophus) penguins. Two additional species, the King (Aptenodytes patagonicus patagonicus) and Rockhopper (Eudyptes chrysocome) penguins, however, are distributed within the Antarctic Convergence. In the vicinity of king Sejong Station located in King George Island, the South Shetland Islands off the Antarctic Peninsula, 5 species are observed, among which 2 Pygoscelis species such as the Gentoo and Chinstrap penguins hatch their eggs and raise their chicks at the rookery 2km south offing Sejong Station in summer. Adelie penguins hatch their chicks in other place in King George Island. One Emperor penguin roamed on the frozen Maxwell Bay which has been frozen every two or three years with the approximate thickness of 60cm. And one Macaroni penguin also visited the rookery in summer. We should carry out researches on the penguins occurring in the vicinity of King Sejong Station to monitor the environmental changes around King Sejong Station and the South Shetland Islands.

  • A new marine tardigrade species of the genus Orzeliscus belonging to the family Halechiniscidae is described from the sea coasts of Korea and Japan. This new species is most characterized in having slender, pole-shaped clava with uniform breadth along its whole length. Furthermore, it evidently differs from the congeners by the combination of characters of a hemispherical protrusion on cheek region of the head, a big and bulbous lateral projection between leg III and leg IV, and an elongate papillus terminating with a minute tube on leg IV. 'Orzeliscus cf. belopus' sensu McKirdy, Schmidt and McGinty-Bayly, 1976 from the Galapagos Islands quite resembles this new species in sharing the slender, pole-shaped clava. However, these two Pacific populations are distinguished to each other by body size and shapes of the protrusion on cheek region and the lateral projection between leg III and leg IV. Scanning electron microscope photographs and a key to species of the genus Orzeliscus are also provided herein.

  • Recent integrative taxonomic research demonstrated a high endemism of Korean copepods, with closest relatives usually in neighboring countries. Although Korean fauna could be considered well-studied, some marginal habitats still provide unexpected discoveries of copepods described from distant parts of the world. Here I report three such examples. Two belong to the family Tetragonicipitidae: Phyllopodopsyllus thiebaudi santacruzensis Mielke, 1989 and Laophontella horrida dentata Mielke, 1992; one to the family Ancorabolidae: Laophontodes norvegicus George, 2018. Scanning electron microscope photographs are provided for the first time for all three species, revealing unknown details of complex three-dimensional structures and ornamentation of somites. Phyllopodopsyllus thiebaudi santacruzensis was described from the Galapagos Islands, while Laophontella horrida dentata was described from the Pacific Coast of Costa Rica; for both this is the second record, which extends their range into the Western Pacific. Laophontodes norvegicus was described from Norway; this Korean record is its first in the Pacific. The first species is represented in my samples by numerous males, females, and juveniles. However, the second one is represented by one adult male and one juvenile female, while the third is represented by a single adult male, which might suggest that the marine interstitial is not their preferred habitat in Korea.

  • 인류사상 가장 위대한 박물학자인 찰스 다윈(1809-82)이 쓴 사상 최고의 과학여행기인 '비글호 항해기'를 지구과학관점에서 검토했다. 항해기에는 지구과학에 관한 여러 가지의 관찰과 해석이 실려있다. 먼저 다윈이 지질시대가 당시 받아들여지던 것보다 훨씬 더 길다는 사실과 조산운동, 융기, 침강, 침식, 퇴적같은 지질현상과 지질과정을 이해했다. 그가 산호초가만들어지는 과정을 완전하게 설명했으며 생물의 진화에 관한 훌륭한 이론을 제안했다. 화석에 바탕을 두고 고환경을 이치에 맞게 복원한 내용이 항해기에 실려있다. 그가 관찰한 기상학에 관련된 내용으로는 대서양을 내려가면서 '비글'호에서 채집한 생물로 된 먼지부터 안데스산맥 능선에서 경험한 공기 움직임과 극도로 맑고 건조한 환경까지 여러 가지에 이른다. 일반 해양에 관한 관찰로는 바다의 변색을 비롯해 해면의 발광, 갈라파고스군도에서 발견된 패류구, 먼 섬에서 발견된 나무와 식물에 관한 것들과 다른 것들이 있다. 그러나 다윈이 육상여행을 상당히 많이 해서인지 천문학에 관한 기록이 거의 없다. 그의 해석과 제안의 대부분이 지금 받아들여진다.
