  • Usnea Adans. is a somewhat rare lichen in South Korea, and, in nearly two decades, no detailed taxonomic or revisionary study has been conducted. This study was based on the specimens deposited in the lichen herbarium at the Korean Lichen Research Institute, and the samples were identified using information obtained from recent literature. In this study, a total of eight species of Usnea, including one new record, Usnea hakonensis Asahina, are documented. Detailed descriptions of each species with their morphological, anatomical, and chemical characteristics are provided. A key to all known Usnea species in South Korea is also presented.

  • Hypotrachyna (Vainio) Hale is a somewhat rare lichen genus found on the Korean Peninsula. Since it was first recorded more than two decades ago, no detailed taxonomic or revisionary study of the genus has been conducted. Thus, the present study was conducted to carry out a detailed taxonomic and revisionary study of Hypotrachyna in South Korea. This study was based on specimens deposited in the Korean Lichen Research Institute (KoLRI). Detailed taxonomic studies and a literature review confirmed the presence of seven species of Hypotrachyna from South Korea, including one new record, Hypotrachyna nodakensis (Asahina) Hale. Descriptions of each species with their morphological, anatomical and chemical characters together with a key to all known Hypotrachyna species are presented.

  • This study on the four families (Leucothoidae, Melitidae, Pleustidae, and Stenothoidae) of gammaridean and the one family (Caprellidae) of caprellidean amphipods of Ulreung Island was based on the materials collected at eight localities in Ulreung Island. Ten species of six genera were identified. Of these, he (Elasmopus korrunus, and Muero breuispina) are new to science. Four species (Leucothoe nogotoi, 1. spinicawa, Paropleustes denhouini, and Stenothoe volido) are new records for Korean craters. Five species were described and six Lvere illustrated.

  • Two stichotrichous ciliates, Amphisiella annulata (Kahl, 1928) and Pseudoamphisiella alveolata (Kahl, 1932), were collected from the Yellow Sea in Incheon, Korea and were identified as new to Korea. The main diagnostic key to the species of the genera are that the two species share the features of two macronuclear nodules, one marginal row per side, and transverse cirri. A. annulata is distinguishable from other members in the genus mainly due to the several ring-shaped (hollow) structures in its cytoplasm and its wide and narrowly arranged amphisiellid median cirral row. P. alveolata has a conspicuous alveolar layer and two conspicuous macronuclear nodules, but no frontoterminal cirri.

  • The interface between nanomaterials and biosystems is emerging as one of the broadest and most dynamic areas of science and technology, bringing together biology, chemistry, physics and many areas of engineering, biomedicine. The combination of these diverse areas of research promised to yield revolutionary advances in healthcare, medicine, and life science. For example, the creation of new and powerful nanosensors that enable direct, sensitive, and rapid analysis of biological and chemical species can advance the diagnosis and treatment of disease, discovery and screening of new drug molecules. Nanowire based sensors are emerging as a powerful and general platform for ultrasensitive and multiplex detection of biological and chemical species. Here, we present the studies about noble metal nanowire sensors that can be used for sensitive detection of a wide-range of biological and chemical species including nucleic acids, proteins, and toxic metal ions. Moreover, the optical and electrochemical applications of noble metal nanowires are introduced. Noble metal nanowires are successfully used as plasmonic antennas and nanoelectrodes, thereby provide a pathway for a single molecule sensor, in vivo neural recording, and molecular injection and detection in a single living cell.

  • The genus Clubiona Latreille, 1804 is the most diverse and largest one in the family Clubionidae Wagner, 1887. Twenty-nine species of the genus have been described in various ecosystems from Korea to date. Clubiona semicircularis Tang, Song and Zhu, 2005 which was formerly only known in China and Clubiona ansa n. sp. were collected with a sweep net on the foliage of the shrubs in mixed forests from mountains and agricultural landscape during a seasonal survey of the spider fauna in Korea. This study describes these two species with a diagnosis, measurements, and morphological illustrations. In addition, the female of C. semicircularis is described with a diagnosis for the first time from the present study.

  • Collema Weber ex F.H. Wigg is scarcely scattered throughout South Korea. However, a detailed taxonomic or revisionary study has not been carried out for almost two decades. The present study was based on specimens deposited in the lichen herbarium at Korean Lichen Research Institute, which were identified using recent literature. In this revisionary study, a total of sixteen species of Collema, including five new records, C. furfuraceum var. luzonense, C. pulchellum var. subnigrescens, C. rugosum, C. subconveniens, C. tenax, and one variety C. leptaleum var. leptaleum were documented. Further, detailed descriptions of each species and their morphological, anatomical and chemical characteristics and a key to all known Collema species of South Korea were reported.

  • Feather mites comprise two superfamilies(Analgoidea and Pterolichoidea) and are highly specialized ectosymbionts of birds. To date, this group contains more than 2,500 species worldwide. Fifty-five feather mite species have been reported in Korea, and only one species of genus Alloptes has been recorded from black-tailed godwit Limosa limosa. Three new records of feather mites from the L. limosa in Korea are added in this study: Avenzoaria punctata Gaud, 1972, Bregetovia limosae (Buchholz, 1869), and Montchadskiana buchholzi (Canestrini, 1878). The genus Bregetovia Dubinin, 1951 is also new report for this country. In this paper, we provide the morphological descriptions and illustrations based on the present specimens. Additionally, we determined partial sequences of the mitochondrial cytochrome c oxidase subunit I(COI) from three feather mites as DNA barcodes.

  • A newly recorded species, Boehmeria nakashimae Yahara, is confirmed for the first time to be distributed on forest edges on Jejudo Island, Korea. This species is known to be endemic to northern Kyushu, Japan. It is characterized by ovate to broadly ovate, elliptic-ovate, or sub-orbicular middle leaf shapes, serrulate-dentate and uniform margins, 17-29 teeth on one side, a short caudate or narrowly acute apex, dense glomerules at fruiting, and densely strigillose on the stems, both surfaces of the leaves, the perianth of staminate flowers, and achenes. Therefore, it is given the new name 'Je-ju-top-mo-si-pul' in Korean based on its serrulate-dentate leaf margin and geographical distribution. A description, photographs, illustrations, and keys of related taxa in Korea are provided.
