  • 생산 하르팍티쿠스목의 갑각류는 지금까지 우리나라에서 12종이 기록되어 있을 뿐이다. 한국의 해산 하르팍티쿠스목 요각류의 분류를 연구하기 위하여 한국산 해조류를 조사한 결과 1992년 6월과 8월에 각각 동해안의 남해와 제주항에서 Lourinia armata(Claus, 1866)가 채집되었다. 이 종은 동북아 연안에서 최초로 보고되는 것이며, 이에 한국산 미기록종으로 재기재하고 도판을 작성하였다.

  • Mitochondrial DNA (mtDNA) polymorphism of the blue mussel (Mytilus edulis) species complex sampled from the east coast of Korean was studied using a partial sequence of COIII gene (336 bp). Samples obtained from three localities on the east coast of Korea revealed four haplotypes with two clearly differentiated mitochondrial clades (termed clades B and E), separated by 4.2% of minimum sequence divergence. This pattern indicates no difference between east and south coasts of Korea. According to population genetic theory on evolutionary characteristics of mtDNA, we concluded that mtDNA introgression from M. edulis to M. gallprovincialis might be a source for mtDNA polymorphism found in mussels on the east coast of Korea.

  • It was studied the relationship between the red tide occurrence and the meteorological factors, and the satellite monitoring for red tide. From 1990 through 2001, the red tide continuously appeared and the number of red tide occurrence increased every year. A common condition for the red tide occurrence was heavy precipitation 2${\sim}$4 days earlier, and the favorable conditions for the red tide formation were high air temperature, proper sunshine and light winds for the day in red tide occurrence. From satellite images, it was possible to monitor the spatial distributions and concentrations of red tide.

  • The Manila clam, Ruditapes philippinaMm (Pelecypoda: Veneridae) is present along the coasts of Korea, China and Japan. In particular, Recently, due to reclamation of tidal areas along the west coast, marine pollution, and reckless overharvesting of this clam, its standing stock has reduced for a decade. Therefore, it is necessary to manage the population of the clam with a proper fishing regime that will maintain an optimal population size in aqua farm. (omitted)

  • People in Korea, a peninsular, have acquired a variety of marine food resources including seaweeds. Ecklonia stolonifera, a brown algae, is commonly dwelling in Korean coasts and their cultivation methods were developed for a mass-production. Recently, studies have revealed that Ecklonia stolonifera is a promising material for the development of health functional foods. In an effort to carefully review the current understating in the effects and mechanisms of Ecklonia stolonifera on liver functions by deduction from relevant literatures, the effective components were identified as phlorotannins, including dieckol, eckstolonol, eckol, phlorofucofuroeckol A, and phlorosterol. Their aiding action on the hepatic functions is categorized as follows. A) Regulation of oxidative stress by anti-oxidant capacity, B) Protection of hepatocytes from toxins, C) Prevention of alcoholic fatty liver and fibrogenesis, D) Regulation of chronic disease by improvement of inflammatory responses and lipid metabolisms, and E) indirect benefit conferred by a personal total wellness.

  • A research probing for the unrecorded and taxonomically undescribed indigenous species has been initiated since 2006. Samples were collected from an intertidal zone along the coasts of Korea as well as around the Jeju Island. We have found five unrecorded species of four genera belonging to the order Dinophysiales, Gymnodiniales, Peridiniales, and Prorocentrales. The species are as follows, Sinophysis canaliculata (2017) Bispidodinium angelaceum (2015), Cabra armorica (2016), Prorocentrum bimaculatum (2017), and P. tsawwassenense (2017) (note; The numbers in parenthesis refer to the year in which the species was reported as unrecorded indigenous species by National Institute of Biological Resources, NIBR hereafter).

  • The pulmonate gastropod Ellobium chinense (Pfeiffer, 1864) is an endangered marine species along the South Korean coasts due to habitat destruction and population declines. We sequenced the cytochrome c oxidase subunit 1 (COI) of 25 E. chinense specimens collected from five coastal sites in South Korea, and identified 16 unique haplotypes. The maximum intraspecific variation among individuals was 1.6%, while interspecific differences from another ellobiid species, Auriculastra duplicata (Pfeiffer, 1854), ranged from 21.9 to 23.0%. Our barcoding data will be useful to elucidate the phylogenetic relationships among pulmonate gastropods and infer the population genetic structure of E. chinense.

  • Aspergillus species play a crucial role in terrestrial environments as degraders and are well known for producing various secondary metabolites. Recently, Aspergillus species have been discovered in marine environments, exhibiting adaptability to high salinity and producing diverse secondary metabolites with valuable properties. However, limited research has focused on their marine diversity, leading to inaccurate species identification. The current study addresses this gap by investigating diverse marine habitats in the Republic of Korea, including sediment, seawater, seaweed, and marine animals. From three coasts of the Korean Peninsula, 472 Aspergillus strains were isolated from the various marine habitats. A total of 41 species were accurately identified using multigenetic markers: internal transcribed spacer, calmodulin, and b-tubulin. The findings underscore the importance of accurate identification and provide a basis for elucidating the functional role of marine-derived Aspergillus species in marine ecosystems.

  • A new oenonid polychaete, Arabella turbidiricolor sp. nov., collected from intertidal zone along the coasts of eastern, western, and southern Korea is described. In Korea, this new species might have been confused with Arabella iricolor(Montagu, 1804), the type species of the genus, in having the following characteristics: ventralmost chaeta tapering gradually to guard, MI left robust and right gracile, MII right long, MV both with one tooth and posterior postchaetal lobe shorter than chaetae. However, A. turbidiricolor sp. nov. is readily distinguished from the latter by the following features: ventral maxillary carriers longer than or equal to dorsal, MI both distally falcate, and pygidium with two swollen pads. We provide detailed descriptions and illustrations for the new species in the present study. Also, morphological characteristics of known Arabella species are compared and discussed with a key to them.
