  • A single specimen (149.9 mm TL) of sagami grenadier, Ventrifossa garmani was collected from Korea waters. This species is similar to Coelorinchus spp. in body shape, but is distinguished by a short and rounded snout. It is characterized by having the serrated second dorsal spine in the first dorsal fin, a triangular spine on the scale, seven branchiostegal rays and six scales below middle of first dorsal fin. We describe this species as the first record to Korean fish fauna and propose the Korean name "Kkeo-kkeul-meo-ri-min-tae-sok" for this genus, and "Kkeo-kkeul-meo-ri-min-tae" for this species.

  • This study investigated concentrations of the several air pollutants and compared antioxidative enzyme activities on Platanus occidentalis because this tree species is one of the widespread street trees in Korea. This species has been emerging the ambient air pollutants during its growing periods. The purpose of this study was to identify the relationship between air pollution on the tree species and antioxidant enzyme activities on the trees. $O_3$, $NO_2$, CO and $SO_2$ concentrations of several cities in Korea were compared for last decades. Among the air pollutants, $O_3$ and $NO_2$ concentrations in six big cities in Korea showed similar increasing trends during this period. In contrast, $SO_2$ and CO concentrations in the same cities dramatically decreased between 1994 and 2005. Platanus occidentalis trees were controlled to investigate, ascorbate peroxidase (APX) and glutathione reductase (GR) activity. Ozone exposure generally increased APX and GR activities of tree seedlings. It is a typical compensatory strategy of stressed trees.

  • The present work was dealt with the twelve species of orbatid mites from leaves, stems and stubbles of rice( Oryza sativa L). Among them six species, that is, Protoribates agricola, Scheloribates decarinatus, Scheloribates oryzae, Sacculozets filosus, Punctoribates manzanoensis, and Paralamellobates ceylanica are new ones in Korea. The other species are Epilohmannia palida pacifica, Podorbates cuspidatus, Tricogaulumna nipponica, Peloribate sp., Scheloribates sp., Galumna sp.

  • This survey conducted to know the species of helminth parasites of cats slaughtered in Daegu during the period from July to September in 1977. A total of 65 cases of internal organs of cats was used for this examination. The results obtained were summarized as follows: 1. Six species of trematodes belong to order digenea were found; Clonorchis sinensis (Cobbolt, 1875), Heteropheys heterophyes nocens (Onji et Nisinio, 1915), Metagonismus yokogawai(Katsurada, 1912), Centrocestus sp. Echinochasmus perfoliattlus (Ratz, 1908), and Echinopharyphium sp. 2. Five species except Clonorchis sinens are firstly recorded in cats in Korea.

  • Based on six specimens collected from eastern coast of Jeju Island, Korea, Istiblennius dussumieri is described as a new Korean record representing the northernmost occurrence of the species in the Indo-Pacific Ocean. The species is characterized by having a dark spot between first and third dorsal spines, branched orbital cirrus, and lacking nape cirri. A new Korean name, "Geom-eun-jeom-be-do-ra-chi" is proposed for the species.

  • Two pelagic species Siriella izuensis Murano and Fukuoka, 2008 and Siriella japonica Ii, 1964, are reported for the first time from the Korean waters, together with descriptions and illustrations. S. izuensis can be distinguished from its closest relative, Siriella japonica, by the normal inner flagellum of the antennule of males, as opposed to the swollen proximal part in S. japonica, and by the slightly more distinct tendency of alternate arrangement of spines on the distal third lateral margin of the telson than in S. japonica. S. izuensis and S. japonica differ distinctly from other related species by a combination of the triangular rostral plate, the moderate size of the eyes, the form and arrangement of the lateral spines of the telson, and six or seven graded spines on the distal outer margin of the uropodal exopod. A taxonomical key is given for the genus Siriella from the Korea waters.

  • The extract contents of various Phellinus species (Hymenochaetaceae) including P. linteus, P. baumii, P. pini and P. igniarius of domestic and foreign products, were examined to standardize the quality of these products. The differences of various extract contents were identified and compared between different species of Phellinus products. The thin layer chromatographic patterns were also analyzed and six unidentified samples were thought to originate from P. baumii and P. igniarius. The chemical standardization for the quality control of various origins could be suggested by this study.

  • Two Campylaspis species, C. amblyoda $Gam\hat{o}$, 1960 and C. reticulata $Gam\hat{o}$, 1960, are redescribed as new to Korean cumacean fauna. Campylaspis amblyoda is characterized by having a carapace with five or six pairs of pellucid spots on dorsal surface, a pair of projections near proximal portion of frontal lobe, and lacking sulcus on lateral portion. Campylaspis reticulata is easily distinguished from its congeners by having a pair of broad sulcus and several large reticulations on lateral portion of carapace. The collected Korean specimens were congruent with the original descriptions, except for several minor differences. Herein, we add two Campylaspis species to the Korean cumacean fauna. The female of C. reticulata is described for the first time. A key to the Korean Campylaspis species is also provided.
