  • The marine algal flora and community of uninhabitated islands in Haenamgun, southern coast of Korea, were investigated during 12$\~$29, June, 1999. As the results, a total of 87 species including 10 greens, IS browns and 62 reds was identified. The dominant species were Ulva pertusa and Sargassum thunbergii and the subdominants were Myelophycus simplex, Ishige okamurae, Hizikia fusifomis, Gloiopeltis furcata and Chondracanthus intermedius. The vertical distribution pattern of intertidal marine algae represented three distinct zones; Gloiopeltis furcata, Caulacanthus okamurae, Myelophycus simplex-Gloiopeltis complanata, G. tenax, Gelidium divaricatum, Ulva pertusa, Sargassum thunbergii-Hizikia fusiformis, Pelvetia babingtonii, Chondrus ocellatus, Undaria pinnatifida, Ecklonia lava from upper to lower zones.

  • The Samurai wasp, Trissolcus japonicus (Ashmead) (Hymenoptera: Platygasteridae) is recognized as a solitary parasitoid on eggs of the stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), an economic pest causing severe damage to fruits, in South Korea. The wasp appears to be a potential biological agent of the pest. In addition, T. itoi Ryu and T. nigripedius (Nakagawa) were found to parasitize eggs of Eurydema gebleri Kolenati and Dolycoris baccarum Linnaeus, respectively. Diagnostic characters and photographs are provided for identification, and host records of Korean Trissolcus species are also given.

  • The feeding habits of bluefin searobin (Chelidonichthys spinosus) were studied based on the examination of stomach contents of 646 specimens collected from January 2005 to December 2005 in the coastal waters off Busan, Korea. The size of C. spinosus ranged from 14.0 to 38.9 cm in standard length (SL). C. spinosus mainly consumed shrimps such as Solenocera melantho, Leptochela sydniesis and Trachysalambria curvirostris. Its diet also included crabs and fishes. Smaller individuals (15~25 cm SL) consumed small shrimps such as L. sydniesis, crabs and fishes. The portion of these prey items decreased with increasing fish size, and this decrease was paralleled with increased consumption of lager shrimps such as S. melantho and Trachysalambria curvirostris. The prey size increased with the increase of fish size.

  • The barbel structure of the spined loach Iksookimia longicorpa were investigated histologically. Their barbels consist of epidermis, dermis, and a central rod. The epidermis contains mucous cells, terminal buds, granular cells, and epidermal cells. The mucous cells are thin rims of basophilic cytoplasm and are located at the surface of the epidermis. The terminal bud is basophilic and is situated at the distal portion of the epidermis. The dermis consists of loose connective tissue containing blood vessels, pigment cells, and nerve cells. The central region of cartilage is the innermost region and is enclosed within muscle layers.

  • We confirmed an unrecorded taxon under the genus Gentianopsis (Gentianaceae) into Gentianopsis contorta (Royle) Ma, which was collected from Geumdaebong, Jeongseon-gun, Gangwon-do in the central part of Korean peninsula. This taxon was known to be distributed mainly Himalayan mountainous area such as India, Nepal and Pakistan, and also growing in China and Japan. In this study, we carried out species description based on the morphological characters, and gave the new Korean name, 'Kko-in-yong-dam' by the characteristics of floral morphology. In addition, some fine figures on several important characters and key to the this and relative species were provided.
