  • Isozyme and protein electrophoresis data from mycelial extracts of 27 isolates of Trichoderma harzianum, 10 isolates of T. aureoviride, and 10 isolates of T. longibrachiatum from Southern Peninsular Malaysia were investigated. The eight enzyme and a single protein pattern systems were analyzed. Three isozyme and total protein patterns were shown to be useful for the detection of three Trichoderma species. The isozyme and protein data were analyzed using the Nei and Li Dice similarity coefficient for pairwise comparison between individual isolates, species isolate group, and for generating a distance matrix. The UPGMA cluster analysis showed a higher degree of relationship between T. harzianum and T. aureoviride than to T. longibrachiatum. These results suggested that the T. harzianum isolates had high levels of genetic variation compared with the other isolates of Trichoderma species.

  • Three penaeid species, Penaeus monodon, P. semisulcatus and Metapenaeopsis lata are reported from the southeastern coast of Korea. P. monodon and P. semisulcatus have been incorrectly known so far as P. bubulus and P. monodon, respectively, in Korea. M. lata is the first record of this species from Korean waters. Morphological diagnoses are given with coloration and distribution for the three species.

  • A new species, Dimorphostylis namhaedoensis (Cumacea, Diastylidae) is described on the basis of the specimens collected from southern shallow coast of Korean peninsula. The new species resembles four other species, D. asiatica, D. valida, D. hisuta and D. acroplicata, in having three apical spines on the terminal margin of the male telson and three pairs of the oblique ridges on the carapace, but are obviously distinguished from them in that the pattern of the ridges on the carapace is different and the third article of the antennular peduncle is very long in female. Furthermore, the dorsal carina of the female carapace has a row of forward spines and among the three apical spines of male telson, the median spine is much smaller than the lateral ones.

  • We examined endophytic fungi from the needle leaves of three species of conifers in Korea: Abies nephrolepis, Thuja koraiensis, Pinus koraiensis. Endophytic fungi were isolated from the surface-sterilized leaves and identified based on morphological characteristics and Internal transcribed spacer sequences of rDNA. Three species of endophytic fungi isolated in this study were the first reported in Korea: Cryptosporiopsis actinidiae, Pestalotiopsis mangiferae, Pyrenochaeta cava.

  • Three new copepod species of Critomolgus are described from the Korean coast of the Sea of Japan. They were found In association with the sea anemones of intertidal and shallow water, one of them from Anthopleura japonica Verrill and the remaining two from Anthopleura midori Uchida and Muramatsu. The descdbed three new oopepods are sympatric and very closely related to one another, though they are easily distinguished from other imown species of the same genus. This is the first record on the sea anemone-associated copepods in the Far East.

  • The wood-rotting fungi of three Korean islands in the Yellow Sea, Soyeonpyung-do (SY), Oeyeon-do (OY), and Gageo-do (GG), were investigated from October 2004 to November 2005. During four sampling trips on each island, a total of 46, 44, and 44 specimens were collected from SY, OY, and GG, respectively. The identified wood-rotting fungi from SY included 29 species of 22 genera and nine families; OY had 31 species of 26 genera and 10 families; and GG had 34 species of 27 genera and 11 families. The majority of the fungi were in the Polyporaceae, which was represented by 23 genera and 30 species. Auricularia polytricha, Daedaleopsis tricolor, Daldinia concentrica, Hymenochaete cinnamomea, Hymenochaete yasudai, Hyphoderma setigerum, Lopharia mirabilis, Schizopora paradoxa, and Trametes versicolor were collected from all three islands.

  • Three freshwater snail species of the family Lymnaeidae have been reported from Korea, Radix auricularia coreana, Austropeplea ollula and Fossaria truncatula. Out of 3 lymnaeid snail species, A. ollula was naturally infected with the Echinostoma cinetorchis cercariae (infection rate : 0.7%). In the experiments with the laboratory-bred snails, F. truncatula as well as A. ollula was also susceptible to the E. cinetorchis miracidia with infection rates of 25% and 40%, respectively. All of three lymnaeid snail species exposed to the E. cinetorchis cercariae were infected with the E. cinetorchis metacercariae. It is evident that A. ollula acts as the first molluscan intermediate host of E. cinetorchis in Korea, and F. truncatula may be a possible candidate for the first intermediate host of this intestinal fluke. Also, three lymnaeid snail species targeted were experimentally infected with E. cinetorchis metacercariae.

  • The Aspergilli of the section Nidulantes series Versicolores are among the most recurrent molds in indoor environments. These species cause damage to the quality of air. Indeed, they are responsible for allergies, aggravation of asthma and can even cause infections in immunocompromised patients. Molds belonging to the Versicolores series also produce sterigmatocystin, a mycotoxin classified as potential human carcinogen by the International Agency for Research on Cancer (group 2B). Here, we provide for the first time the genome of three species of the series Versicolores: Aspergillus creber, Aspergillus jensenii and Aspergillus protuberus which are the most abundant species of this series in bioaerosols. The genomes of these three species could be assembled with a percentage of completeness of 97.02%, 96.21% and 95.35% for Aspergillus creber, A. jensenii and A. protuberus respectively. These data will allow to study the genes and gene clusters responsible for the expression of virulence factors, the biosynthesis of mycotoxins and the proliferation of these ubiquitous and recurrent molds.

  • The species composition and biomass of marine algae at the discharge canals of three (Gori, Wolseong and Uljin) nuclear power plants on the east coast of Korea were investigated seasonally from February 1992 to October 2000. As a result, 103-107 species of marine algae were found at the discharge canals during the past nine years. In general, algal communities established at the discharge canals were less diverse than those at the intake canals and control sites. 43 species (6 blue-green, 9 green, 10 brown and 18 red algae) of marine algae occurred more than 1/6 frequency and thus can be categorized as warm tolerant species. Among these, two green (Urospora penicilliformis, Cladophora albida), four brown (Sphacelaria divaricata, S. rigidula, Sargassum coreanum, S. fulvellum) and four red algae (Stylonema alsidii, Bangia atropurpurea, Hypnea charoides, Chondria crassicaulis) are recorded as warm tolerant marine algae for the first time in Korea during this study. Enteromorpha compressa, Padina arborescens, Amphiroa zonata and Ahnfeltiopsis flabelliformis were common species found more than 50% frequency at the discharge canals of all three nuclear power plants investigated. Dominant species in biomass were Padina arborescens and Amphiroa zonata. Results showed that, as a whole, the red algae appeared as predominant algal group at the discharge canals of all three nuclear power plants on the east coast of Korea. However, the biomass proportion of dominant algae at the discharge canals of each nuclear power plant varied over the year during the past nine years.
