  • 한국에 백록고사리[Tectaria fuscipes (Wall. ex Bedd.) C. Chr.]를 처음으로 보고한다. 이 종은 한국에서 보고된 바 없는 미늘창고사리과(Tectariaceae Panigrahi)의 미늘창고사리속(Tectaria Cav.)에 속한다. 백록고사리는 거의 직립하거나 비스듬히 올라가는 지하경, 이형엽 또는 반이형협, 유리맥이 있는 특징이 있다. 이종은 제주도 서귀포시 한라산 남서부 사면에 분포하고 있으며, 중국의 남부지역과 대만에서도 자생한다. 일본에는 미늘창고사리속 식물 8종이 보고되어 있으나 백록고사리는 아직 보고되지 않았다. 제주도는 지금까지 알려진 백록고사리의 분포 지역 중 가장 최북동 지역이며, 그 서식처는 작은 수직동굴 내부로 한정되어 있다.

  • The genus Luidia belongs to the family Luidiidae in the order Paxillosida. It is a common littoral taxon, and the depth range of the Korean fauna is generally 0-100 m. However, specimens of Luidia were collected from Jeju Island in Korea at 150-160 m depth and identified as Luidia sagamina sagamina $D{\ddot{o}}derlein$, 1920. This species is determined by morphological characteristics and mitochondrial cytochrome c oxidase subunit I sequence analysis. Luidia sagamina sagamina is a very rare sea star in worldwide and it only collected previously from Sagami Bay, Japan, and is newly reported in Korea. Four species of Luidia, including L. s. sagamina, are recorded in the Korean fauna.

  • 한반도의 서남 도서지역인 대흑산도에 서식하는 당근속(Daucus)식물의 외부형태학적 형질을 중심으로 하여 분류학적 재검토를 수행하였다. 또한, 대흑산도의 해안 지역에 서식하고 있는 당근류를 갯당근(Daucus littoralis Sibth. et Sm. var. koreana Nakai)으로 여러 도감에 기재되어 있어, 이들에 대한 식물명 및 분류학적 실체에 대하여 조사하였다. 갯당근으로 동정되어 있는 석엽표본과 현지 조사 결과, 해안에 서식하는 당근류는 잎 및 열매의 형태에서 차이를 보여 D. littoralis가 아닌 D. carota L. subsp. carota로 밝혀졌으며 상기 아종의 국명을 당근(D. carota subsp. sativa)와 구별하기 위해 산당근으로 신청하였고, 줄기가 곧으며 갈라지지 않는 미기록 분류군인 D. carota subsp. maritimus의 국명을 선당근으로 신청하였다.

  • This study aimed to elucidate the distribution of vascular plants on the Deok mountain in Ganghwa-gun, Korea. The results of 10 field surveys from March to October of 2019 identified 532 taxa in total, representing 482 species, 9 subspecies, 39 varieties, 1 form, and 1 hybrid in 318 genera and 105 families. The plant formation of Deok mountain is the deciduous broad-leaved and conifer mixed forest, which is the common one in the middle region of the Korean Peninsula. Among them, 301 taxa were newly recorded in this study, 7 taxa were endemic plants to Korea, 3 taxa were red list plants. The floristic target plants amounted to 41 taxa, specifically 1 taxon of grade V, 2 taxa of grade IV, 7 taxa of grade III, 9 taxa of grade II, and 22 taxa of grade I. Alien plants were recorded a total of 73 taxa with a naturalized index of 13.7%, the urbanization index was calculated to be 11.8% and 4 taxa were ecosystem disturbance plants.

  • Background: Several investigations carried out from large brackish lagoons in South Korea. However, no studies have yet examined phytoplankton in lagoons that changed to freshwater, such as Cheonjin Lake. The present study examined the algae from Cheonjin Lake. Methods: Samples were collected at monthly inetrvals from May 2017 to April 2018, from the surface layer using a plankton net (mesh size $20{\mu}m$), and sequeezing submerged macrophytes. Microscopic examinations were conducted at a magnification of 200 to 1000x using a Zeiss microscope (Axio Imager. A2), and photographs were taken with an AxioCam HRC camera. Silica-scaled samples of Chrysophyta for SEM were placed on coverglass, air dried, coated with gold, and then examined with a Hitachi SV8220 SEM. Results: A total of 376 taxa from six major algal groups (Chlorophyta, Chrysophyta, Euglenophyta, Cyanophyta, Dinophyta, and Cryptophyta) were identified. Among these algae, 28 taxa of desmids, 9 taxa of Euglenophyceae, 4 taxa of Chlorophyceae, 2 taxa of Chrysophyceae, and 1 taxon of Xanthophyceae are reported for the first time in Korea. A new species, Cosmarium hexagonum sp. nov was described. The phytoplankton communities were characterized by an abundance of Desmids (within Charophyceae) accounted for 148 taxa from 22 genera. Species richness were particularly high in the Autumn. Conclusion: In this study, a total 376 taxa of 148 desmids (Charophyceae), Chlorophyceae (103 taxa), Chrysophyceae (53 taxa), Euglenophyta (49 taxa), Dinophyta (8 taxa), and Cryptophyta (2 taxa) were identified from Cheonjin Lake. Twenty-eight taxa of desmids including a new species (Cosmarium hexagonum sp. nov.), 9 taxa of Euglenophyceae, 4 taxa of Chlorophyceae, 2 taxa of Chrysophyceae, and 1 taxon of Xanthophyceae were newly recorded in Korea.

  • The physico-chemical and environmental factors of stoneworks were examined from March 2009 to October 2010, and aerial algae living on 24 stoneworks in Korea were identified. Fifty aerial algae were found in 24 stoneworks. Of the 50 taxa, 30 taxa were cyanophytes, 16 taxa were bacillariophytes, 3 taxa were chlorophytes, and 1 taxon was a xanthophyte. Nine species, including Aphanocapsa rivularis, which is known to only live in aquatic conditions, inhabited both aquatic and aerial environments. Synechococcus aeruginosus, Scytonema coactile var. thermalis, S. coactile var. minor, Stigonema ocellatum f. ocellatum, and Oscillatoria boryana were newly recorded in Korea. As a result of a correlation analysis between algae and the physico-chemical and ecological environmental factors, the taxa were divided into the bryophyte group, the humidity group, and the dry group. Although the bryophyte group was included within the humidity group, it was separated from the dry group. Taxa in the bryophyte group including Nostoc commune which was distributed in more humid areas than those in the humidity group. However, dry group taxa including Chroococcus pallidus were distributed in lower humidity than that of the two other groups. Correlations among other environmental factors were tested to identify other factors that could substitute for humidity and light intensity. As a result, tree distance, water distance, and plant coverage were replaceable environmental factors.

  • 처녀이끼과 미기록 분류군 두메괴불이끼(Crepidomanes schmidtianum)가 지리산(경상남도 함양군 마천면 백무동)에서 발견되었다. 두메괴불이끼는 괴불이끼속의 다른 분류군들에 비해서 위맥이 있고, 잎자루에 날개가 거의 없으며, 위가 갈라지고 컵모양인 포막을 갖는 점이 뚜렷이 구별된다. 새로운 국명은 높은 산에서 자란다는 의미로 두메괴불이끼로 하였고, 주요형질에 대한 종기재 및 해부도와 서식지 식물사진 및 한국산 괴불이끼속 식물에 대한 검색표를 제시하였다.
