A parasquillid stomatopod, Faughnia haani(Holthuis, 1959), collected from Jeju Island, is reported for the first time in Korea. This species is characterized by the presence of obtuse anterolateral angles of carapace, median and three pairs of longitudinal carinae on telson, and crenulate inner margin of uropodal protopod. In this paper, a detailed description and illustrations are provided. As a result of this study, the geographical distribution of the present species is extended and 15 species of stomatopods including this species are now recorded in Korean fauna. The specimen examined herein was deposited in the National Institute of Biological Resources(NIBR).

Rhogadopsis속은 주로 굴파리에 기생하는 고치벌로 Opius속의 아속으로 여겨져왔다. 그러나 시맥의 형태와 단계통 분기군을 형성함에 따라 Rhogadopsis속은 속으로 격상되었다. 전라남도 여서도에서의 동물상 조사 결과, Rhogadopsis obliqua의 수컷 표본을 쓸어 잡기로 채집되었다. Rhogadopsis obliqua의 기술과 진단 형질 도판을 수록한다.

Archidium ohioense Schimp. ex Müll. Hal.는 국내 자생 정보가 부족했던 종으로 본 연구를 통해 경기도 연천군 전곡읍 간파리 감악산에서 신분포지를 확인하였다. A. ohioense가 속하는 Archidium Brid. (Archidiaceae)는 극지방을 제외한 아열대지역에서 온대지역까지 분포하며, 총 36종이 생육하는 것으로 알려져 있고, 최근 anti-inflammatory와 antisickling potentials에 관한 효능 연구가 수행되고 있다. A. ohioense의 잎은 난상피침형~삼각상피침형으로 잎가장자리는 밋밋하나 잎끝에 미세한 치돌기가 있다. 잎맥은 굵고 1개이며 잎끝까지 또는 짧게 돌출되어 있다. 중앙세포는 마름모형, 긴 선형의 마름모형이고, 익부세포는 마름모형에서 직사각형이다. 추후 분자생물학적인 연구 및 생태학적인 연구가 추가된다면 안정적인 자원화에 기여할 수 있을 것이라 사료된다.

The purpose of this study was to identify the natural habitat of Bulbophyllum inconspicuum Maxim. in Hongdo, Jeonnam Province, South Korea. A field investi gation was conducted between May 2019 and May 2021. The growth of B. inconspicuum species was confirmed in three known regions based on National Survey on the Distribution of Endangered Species. Additionally, in the area investigated, 37 new regions harboring B. inconspicuum were detected. The newly observed B. inconspicuum grew naturally on Quercus mongolica, Rhaphiolepis indica var. umbellata, Carpinus turczaninowii, and rocks. Most of them were found on southeast and southwest slopes with altitude above 250 m. As few as 10 up to hundreds of B. inconspicuum were found in clusters. Close to their habitat, Calanthe sieboldii Decne. ex Regel, C. aristulifera Rchb. f. and C. × kibanakirishima Maek. were also found. As Hongdo is an island, multiple endangered species were found together. Thus, once the habitat of a certain plant is discovered, it is very likely that illegal collection of several other species will also occur. Proactive internal and external measures are needed to preserve these species.

The category killer that has been rapidly growing mainly in advanced countries since early 1990's, is a mew distribution model which aims for obtaining market controlling power by surpassing competing businesses in a specific area of products. The domestic situation of category killers is very different from that of advanced ones abroad since it has just been introduced into the Korean market. At the moment, there are only 10 or so companies operating in the market : Geopyung's , Taeheng's , Midopa's , of Sinsegye Department store, adn of Yerim International. The purpose of this study is to examine problems of domestic companies in the present market by analysing the operation status of category killers in domestic markets as well as foreign ones, and to suggest a counter-strategy of category killers for the distribution environment of the 21st century to improve the competitiveness of Korean distribution industry. The competitiveness of category killers lies above all in products lines. Category killers are equipped with the greatest number of products lines among those of competing businesses due to maximized product selections in an limited range. Another source of competitiveness may be found in balanced strategy positioning. That is to say, category killers are in a position where they can adjust policies towards any of the three purposes while aiming at them altogether : prices of discount stores, products range of specialty stores, and customer service level of department stores. It is also necessary for efficient store operation to use information technology such as electronic data interchange (EDI), electronic pose system(EPOS) and electronic funds transfer (EFTPOS). As for the cost structure, category killers can gain an advantage over other business since operating cost of various sections can be saved. There are, however, certain risks that category killers with strong competitiveness may influence on other businesses a great deal and even facilitate their decline. Yet it seems that the growth of category killers will be more viciously restrained by continuous challenges from other businesses. The distribution industry is supposed to develop through such competition and restraint.

The marine brown algal genus Colpomenia has a worldwide distribution, with five species reported in Korea and Japan. However, no studies to date attempted to identify the number of species and geographical distribution of Colpomenia along Chinese coast. To fill the biodiversity knowledge gap, we analyzed 63 mitochondrial cox3 and 62 mitochondrial atp6 sequences of Colpomenia specimens collected from 30 localities along the Chinese coast. Maximum likelihood and Bayesian inference trees suggest the presence of at least three Colpomenia species (i.e., C. peregrina, C. claytoniae, and C. sinuosa) in China. C. peregrina and C. claytoniae are documented for the first time. C. sinuosa was only found in the South China Sea and its distribution didn't overlap with that of C. peregrina which was found in the Yellow-Bohai Sea and the East China Sea. C. claytoniae appears to be confined to three isolated islands in the East and the South China Sea, where it occurs in sympatry with, respectively, C. peregrina and C. sinuosa. Future study can focus on comparing eco-physiological differences of Colpomenia species in response to environmental variables and exploring possible genetic hybridization / introgression at inter-specific contact zones.

A study on the presence of benthic dinoflagellates in the intertidal zone along the coasts of Jeju Island, Korea was conducted during 2011 and 2012. Identification and taxonomic observations were made of the benthic dinoflagellate samples using light and epifluorescence microscopy. Thirty-seven dinoflagellate taxa belong to five orders, nine families, 18 genera and 30 species, which are new records for Korean waters, were detected in this study. The detailed nomenclature, references, distribution, and illustrations are presented here. The commonly occurring genera were Amphidinium, Coolia, Ostreopsis, Prorocentrum, and Thecadinium. Among the recorded species, 26 were found only in sand sediment, seven in macroalgal samples, and four were found in both sand and macroalgal samples. Of the 37 species, nine were potentially toxic. These results suggest that diversified benthic dinoflagellates including several potentially toxic species occur in sand sediment and macroalgae in the intertidal zone along the coasts of Jeju Island. The morphological features of the identified species were more or less similar to observations made by previous studies in Korea and elsewhere. The presence of known toxic species may indicate a potential risk of toxicity in the marine ecosystem of Jeju Island. The present study can be helpful for further detailed taxonomic, toxicological, molecular phylogenetic studies and may help in the management and conservation of Jeju Island's marine ecosystem.
