The rotifers inhabiting several lowland swamps in Kyngsangnam-do were taxonomically investigated. Collectings were carried out four times at 10 sites in such lowland swamps as Up, Chunam-ji , Chilnal-np and Oisong-np from 22 February 1988 to 2 October 1988. As a result, 4 spcies, 9 subspecies, 2 varieties and 2 forms of monogonont rotifiers in 5 families were identified, of which following 3 species and 3 subspecies are new to Korea ; Testudinella mucronata hauerensis, Platyias quadricornis , Mytilina acanthophora, Lecane ungulata ungulata. Trichocerca bicristata bicristata, and Dicranophorus epicharis.

This study was carried out to immunologically characterize Bacillus thuringiensis (B.t) antigens. Protein patterns of ultrasonicated- antigens of B. thuringiensis subspecies using SDS- PAGE revealed marked similarities among all the strains analyzed except for the difference between quantative variations of bands and some protein antigens. The comparison of the protein patterns showed that the protein antigen of 45 kilodalton (kd) was common in 11 strains and that the difference between B. thuringiensis subsp. canadensis and galleriae was noticed in quantative variations of bands despite of ambiguous serogrouping, suggesting a useful method for identification. All strains examined showed similar antigenic patterns in SDS-PAGE, while immunodominant bands differed in antigenic reactivity in western blot using polyclonal antibodies. Polyclonal antibody to B. thuringiensis subsp. thuringiensis and israelensis in indirect immunofluorescence assay reacted with flagella and cell surface antigens. The present study indicates that SDS-PAGE and western blot analysis may be used as tools for differentiation and identification of B. thuringiensis subspecies.

The present faunistic study, on the marine harpacticoids of Chindo Island, Korea was based on the materials collected from various habitats during the periods from October 23-24 in 1993and July 23-25 in 1994. As a result of examining the specimens, 9 species or subspecies of 6 families were identified , of which 6 species or subspecies were newly recorded from Korea : Tachidius (Tachidius) discipes Giesbrecht, 1881 : T.(Neotachidius) triangularis Shen and Tai, 1963 ; Scutellidium longicauda acheloides Ito, 1976 ; Alteutha depressa (Baird, 1837) ; Amonardia normani (Brady, 1872) ; Onychocamptus bengalensis (Sewell, 1934).

The authors examined intertidal and sublittoral balanomorph barnacles which were collected from 38 localities in South Korea during the period from 1963 to 1978. 2. Identified and classified materials are composed of 15 species and 2 subspecies, all of which are described, under 10 genera and 5 damilies, of which 2 species and 1 subspecies are new to Korea as follows: Chelonibia patula, Chirona (Striatobalanus) amaryllis, Solidobalanus (Hesperibalanus) hesperius hesperius. 3. As dominant species, Chthamalus challengeri and Tetraclita squamosa japonica are widely distributed in Korea through East Sea, South Sea and Yellow Sea. 4. Balanus albicostatus and B. kondakovi are commonly found in intertidal brackish waters of Yellos Sea and South Sea, whereas, B. trigonus and Megabalanus rosa are typical sublittoral forms.

The Mediterranean Sea is currently facing dramatic changes and threats, including change in native species and accidental introductions. The introduced green alga Codium fragile subsp. fragile (Suringar) Hariot influences diversity and community structure in some parts of the world. This paper documents the distribution of this species in Tunisia and provides a morphological description of C. fragile subsp. fragile in Northern Tunisia. Results confirm the identity of Tunisian specimens as the invasive subspecies C. fragile subsp. fragile. This is the first morphological characterization of this subspecies in Tunisia.

The phylogenetic analysis was carried out to find out the validity of Chrysochroa coreana as a new species. The insect specimens were collected at Kaohsiung, Taiwan and Shizuoka, Japan. Partial region (532 bp) of COI was amplified and sequenced. The sequences were aligned and then analyzed. Based on the Kimura-2-parameter method, we calculated genetic distances among them. It indicated that the Korean individual of C. fulgidissima was closely related to Taiwan one with relatively low genetic distance (0.083). On the other hand, the Japanese individual was remotely related with those of Korean (0.192) and Taiwan (0.183) individuals. To clarify if the populations of C. fulgidissima from Korea, Taiwan, and Japan are different at the level(s) of subspecies, species, or genus, it is necessary that more samples of the members of the family Buprestidae should be collected and genetically analyzed.

한국산 야생 생쥐(Mus muscurus subspecies)와 동계교배 계통인 BALB/c의 정모세포에서 감수분열에 따른 염색체의 chiasma 말단화 여부와 chiasma 빈도, X-Y 염색체의 조기 분리 빈도 등을 조사하였다 한국산 야생 생쥐에서는 chiasma 말단화가 일어나지 않는 것으로 나타나 말단 chiasma는 말단 부위에 특이적으로 생긴 chiasma로 생각되며, chiasma 빈도의 감소와 univalent 빈도의 증가에 관한 ageing의 영향도 관찰되지 않았다. 불임개체에서 X-Y 염색체 조기 분리가 낮은 빈도로 나타나 동계교배 계통과는 다소 상반된 결과를 보였고, chiasma 빈도는 한국산 야생 생쥐가 동계교배 계통에 비해 다소 높게 나타났으며 복사기, 이동기 및 중기 1을 거치는 동안 거의 일정한 수준을 보여주었다. 또한 한국산 야생 생쥐에서 특징적으로 개재 chiasma 빈도 보다 말단 chiasma 빈도가 높게 나타났으며 이에 대해서는 부가적인 연구가 뒤따라야 할 것으로 사료된다.

The rosters collected loom various keshwater habitats, such as rivers, steams, lakes, ponds, and rice paddies at twenty-four different sites in Korea were investigated. Eleven species and/or subspecies in three families of monogonont freshwater rotifers were identified, of which two species, Notholco marina and Lecane (Monostyra) stenroosi stenroosi were new to Korea. A key is presented for the twenty-two Korean species and/or subspecies which have been described by the previous taxonomic reports and the present study.

The isozymic polymorphism among the Oncorhynchus masou subspecies (O. m. masou and O. m. ishikawai) and the genetic variation in the O. mykiss species (rainbow trout and its albino mutant) were examined in present study. The biochemical marker might be identified at the sublevel of species. The aims of this study is to examine such feasibility of using the isozyme polymorphisms of the fish management and characterization between subspecies or morphomutants such as albinism. (omitted)

Psalidoremus is one of the subgenus which consists of five species and eleven subspecies through Taiwan, Japan, Korea and north eastern part of China which present strong endemism to their distribution. While most of advance studies focus on the new species or subspecies from this taxon, this paper suggests paleogeographical assumption and hypothesis of how they diverged from common ancestors. Phylogeographical patterns illustrated by the distribution of five species, which including Prosopocoilus inclinatus, Prosopocoilus hachijoensis, Prosopocoilus dissimilis, Prospocoilus pseudodissimilis, Prosopocoilus motschulskii respectively, has been assessed in this research. Speciation history is suggested by morphological tendencies especially in male mandibles with assumption from geographical patterns of under sea level.
