In this study, an attempt has been made to analyze the morphology of Cephalopods distributed in Korea and collected samples from South-East Asian countries including Thailand, Indonesia, Vietnam, and China. A phylogenetic analysis was performed using the mitochondrial gene, Cytochrome c oxidase subunit I (COI) to understand the genetic divergences of the species and validate their origins. For achieving the objectives, samples were collected directly from Thailand Hat Yai, Songkhla, Indonesia Medan, Vietnam Ho Chi Minh, and Vung Tau in August 2015 and from China in September 2015. A total of 23 species of Cephalopods were identified falling under three orders, four familyies and nine genus. The species were distributed under Order: Octopoda (1 family, 3 genus, and 9 species), Order: Sepiolioda (1 family, 2 genus, and 8 species), and Order Teuthoidea (2 family, 4 genus, and 6 species). 23 species which is 1 family 3 genus 9 species in Octopoda, 1 family 2 genus 8 species in Sepiolioda, 2 family 4 genus 6 species in Teuthoidea. Phylogenetic analysis using COI gene was conducted for 18 species. For the remaining 5 species sequencing results showed severe variation and hence were not considered further. The COI phylogenetic analysis for the 18 species of Cephalopods were found consistent with the morphological identification. The excluded species will be subjected for a further detailed analysis.

We report three newly recorded campoplegine species, Klutiana jezoensis (Uchida, 1957), Dusona maruyamator Hinz, 1979, Dusona petiolator (Fabricius, 1804), for the first time from Korea. Genus Klutiana Betrem (1933), is firstly recorded from Korea. Photographs and diagnosis are provided for identification.

Taxonomic study of the crustose lichen Porpidia was performed in this paper. Three species are described, including two recorded species and one new record: Porpidia macrocarpa (DC.) Hertel & A. J. Schwab. A description of each species is presented along with morphological, anatomic, and chemical characteristics. A key to the identification of species of Porpidia is also presented.

Four flavonoids were isolated from the whole plant of Kyllinga brevifolia var. leiolepsis. Their structures were identified as quercetin, (-)-epiafzelechin, vitexin and orientin on the basis of spectral data. This is the first report of the identification of quercetin, (-)-epiafzelechin and orientin from Kyllinga genus.

A fungal internal transcribed spacer region was used to identify the mycorrhizae of Cymbidium kanran. The family Russulaceae was found to be the most frequently occurring group in both root and soil samples. In phylogenetic analyses, the majority of the Russulaceae clones were clustered with Russula brevipes and R. cyanoxantha. Therefore, C. kanran may form symbiotic relationships with the genus Russula.

Detergent-degrading bacteria isolated from the Han River downstream running through the center of Seoul area were identified. Samples were monthly taken from the surface waters at four designated sites from October, 1980 to August, 1981. Isolated strains were characteristically Gram-negative bacteria in all, and they were classified within 18 genera, 43 spceies. The dominant strains of detergent -degrading bacteria were within geneus Pseudomonas. On the regional distribution of detergent-degrading bacteria, Euterobacteriaceae and genus Aeromonas were suddenly increased at the Third Bridge of site 2 and the First Bridge of site 3, and others were almost the same regardless of sites.

Gnetum (Gnetaceae, Gnetales) is a gymnosperm genus with ca. 35 species distributed in tropical forests around the world. Due to its dioecious habit and lack of diagnostic characters from vegetative tissue, the identification of Gnetum species is not easy without seeds or reproductive structures. To identify and verify their phylogenetic positions, we applied DNA barcoding to Cambodian Gnetum collections gathered between 2010 and 2015, with previously designed cp matK gene primers. We newly sequenced partial matK sequences from 72 Gnetum collections, 43 out of 72 from Cambodia, and analyzed 115 Gnetum accessions using the neighbor-joining method. The resulting neighbor-joining tree categorized Cambodian Gnetum samples into three clades of species: G. macrostachyum, G. montanum, and G. aff. gracilipes. The recognition of G. aff. gracilipes in Cambodia is reported here for the first time. Taxonomic information for the three recognized Cambodian Gnetum species is provided and the benefits of the taxonomic reevaluation assisted by DNA barcoding are emphasized in this work.
