We report the first occurrence of Ophichthus erabo (Jordan and Snyder, 1901) collected in the waters around Jeju Island. The morphologic characteristics of this species include rich brown semicircular spots distributed on the head, the back, and the dorsal fins. Ophichthus erabo has a similar body color to Ophichthus polyophthalmus but can be clearly distinguished from the latter by the number of vertebrae (152-155 in O. erabo vs. 147-149 in O. polyophthalmus) and the existence of a white spot at the center of a semicircle (i.e., no white spot in O. erabo vs. a white spot in O. polyophthalmus). We suggest a new Korean name for O. erabo to be "Mul-bang-ul-ba-da-baem-gang-eo".

The community structure and health status of macrobenthos assemblages were investigated in the subtidal area of the Nakdong River estuary, Southern Coast of Korea. Benthic fauna samples were collected seasonally at 8 stations in the subtidal area of the Nakdong River estuary from February 2013 to October 2015. During the survey, a total of 380 species and 4,603 ind./m² of macrobenthos in all sampling areas were collected. The major dominant species were the polychaetes Minuspio japonica, Pseudopolydora kempi, Heteromastus filifomis, Capitella capitata, the amphipod Grandidierella japonica and the bivalvia Arcuatula senhousia. Some species of polychaetes found in the study area consisted of opportunistic species that showed high densities when habitat condition was poor. On the other hand, macrobenthos assemblages in the study area were divided into brackish water and marine groups. Abundance was high in the brackish group, while the number of species and diversity index were high in the oceanic group. The three indices (AMBI, M-AMBI, and BHI) in the assessment of health levels based on the ecological characteristics and number of species in macrobenthic were commonly shown to be in good condition in the group of oceanic stations, while relatively poor conditions were reflected in the group of brackish stations. Compared to other indices, the M-AMBI index of the three indices for health assessment was considered to be a relatively more suitable one to assess benthic ecological conditions.

Basic bioactivities (antioxidant, anti-inflammatory, antibacterial, anticancer, antiviral) were investigated from 370 strains of marine bacteria, fungi, and microalgae obtained from various marine environmental regions in Korea, and the activity results were obtained at the collection site, isolation source, and species level was compared. In the case of marine bacteria, strains belonging to the generally useful genera Streptomyces and Bacillus were observed to have particularly strong efficacy and useful resources were mainly isolated from marine sediments. In the case of marine fungi and microalgae, results showing strong species-specific activity were confirmed, and results showing efficacy-specific activity were also obtained. Based on these results, it is a research result that can facilitate priority access as a strategic material for industrial revitalization and the establishment of a strategy to secure resources based on usefulness when conducting research on chemicals that are selectively effective against specific diseases or when conducting resource-based research. In addition, we believe that by using these results as material for sale through the Marine BioBank (MBB), academia and industry can use them to help accelerate the revitalization of the marine bio industry.

We presented detailed morphological descriptions of the eggs, larvae and juvenile of Acanthaphritis unoorum based on specimens collected with bongo nets from Korean waters during the period May 2017-July 2018. We collected 18 individuals including eggs (n= 4, 0.77-0.85 mm in egg diameter), preflexion larvae (n= 6, 4.11-6.31 mm in standard length, SL), flexion larvae (n= 4, 6.60-7.82 mm SL), postflexion larvae (n= 3, 8.94-13.46 mm SL), and one juvenile (n= 1, 14.67 mm SL). The mitochondrial (mt) DNA 16S rRNA sequences of the eggs, and the cytochrome c oxidase subunit I (COI) sequences of the larvae were identical to those of A. unoorum adults (genetic distances <0.01). The A. unoorum larvae and the juvenile that we collected were morphologically similar to those of Dactylopsaron dimorphicum, but the A. unoorum specimens were readily distinguishable by the presence of lateral melanophores. This is the first record of A. unoorum in Korean waters. We propose a new Korean name for A. unoorum: "O-ri-bu-ri-nuntung-i".

The genus Ippa Walker, 1864 is reported for the first time from Korea, with a species I. conspersa (Matsumura, 1931). I. conspersa is generally known as myrmecophiles having ecological relationships with some ant species such as Lasius spp. Photographs of adults, immature stages, and the genitalia of I. conspersa are provided.

The monthly variation in species composition of fishes in the Gujora and Mangchi coastal waters in Geoje, Korea, was investigated between June 2018 and May 2019 through monthly fish collections using a gill net. A total of 46 species, numbering 410 individuals weighing a total of 96,645.0 g, were collected during the study period. The dominant species in terms of numbers were Chelidonichthys spinosus, Stephanolepis cirrhifer, Ditrema temmincki, Sillago japonica, Sebastes inermis, and Paraplagusia japonica. The number and biomass of fishes peaked in July. The peak in species diversity indices occurred in September. The cluster analysis revealed that there were four groups of fishes depending on the season. In addition, subtropical fishes were recorded in the study area, indicating the gradual subtropicalization of the coast of Geoje. Furthermore, the need to understand the changes in marine ecosystems owing to subtropicalization through continuous monitoring is emphasized.

Two specimens (1770~1850 mm disc width) of Mobula thurstoni, belonging to the family Myliobatidae, order Myliobatiformes, were first collected from the central coast of the Southern Sea of Korea in September 2018. This species is characterized by an anterior margin of disc with double curvature, a white-tipped dorsal fin, and the absence of a caudal spine. This species is morphologically similar to Mobula kuhlii, but has an anterior margin of pectoral fins with a double curvature and the dorsal coloration is bluish black rather than white. In addition, M. thurstoni was well distinguished from M. kuhlii as determined by mitochondrial DNA 16S rRNA sequences with genetic distances ranging from 0.030 to 0.069. The Korean name 'Mae-kkeun-kko-li-jwi-ga-o-li' is proposed for the species M. thurstoni.

북한식물은 남한이 아닌, 북한 또는 이북지역에 자생하는 식물이며 DMZ자생식물원은 국내 유일의 북한식물 연구센터로서 한반도의 생물다양성 자료구축, 보전, 활용에 관한 연구를 수행하고 있다. 동아시아의 생태계를 이해하고 통일 이후의 황폐화된 북한의 식생 복원 기반 구축 및 산업화 소재 발굴을 위해 북한식물에 관한 체계적인 자료정리와 북한식물 유전자원(표본, 생체, 종자) 수집전략이 요구된다. 본 연구는 국내·외 수목원 및 관련기관의 북한식물 유전자원에 대한 보유 현황을 파악하기 위하여 수행되었다. 조선식물지 등 북한식물 종에 관한 문헌과 전문가 검토를 거쳐 북한식물 DB를 구축하였다. 국내·외 수목원 DB에 북한식물 학명을 검색하여 각 수목원의 북한식물 유전자원 보유 현황을 확인하였다. 북한식물 480 분류군에 대하여 국내 14개 수목원을 포함한 전 세계 6개 대륙, 42개국, 283곳의 수목원을 탐색한 결과 총 432 분류군에 대한 보유 현황을 파악하였다. 189 분류군에 대한 1,475 점의 표본정보를 확보하였으며, 327 분류군에 대한 3,652 건의 생체 및 종자 보유 여부를 확인하였다. 본 연구를 바탕으로 북한식물 유전자원을 체계적으로 수집하여 향후 한반도 생물다양성의 이해를 증진시키고 북한지역 생태계의 보전 및 복원에 기여할 수 있을 것이라 생각한다.
