제주도의 기온온난화가 한라산 고산식물 분포에 미치는 영향에 대한 연구의 하나로 한라산 고산식물 8종의 수평 및 수직 분포역과 생육환경이 조사되었다. 그 결과 희귀하거나 멸종 위기 상태에 있는 고산식물들에 관한 생물지리학적 기초 자료와 정보가 축적되었다. 한라산 고산식물은 분포특성에 따라 8가지 유형으로 분류되며, 그 중 70퍼센트 정도가 한반도의 고산지나 일본열도의 것들과 공통적인 것으로 밝혀졌다. 이들은 빙하기 동안 동북아시아에서 한반도를 거쳐 제주도로 유입되었고, 일부는 일본열도에 전파된 것으로 생각된다. 현재 이들 고산식물은 열악한 기후, 척박한 토질과 지질 그리고 동결과 융해가 반복되는 주빙하성 환경에 적응하여 산정부 일대에 주로 분포한다. 본 연구는 한라산 고산식물의 분포와 과거 및 현재 환경과의 관계에 대한 기초 자료를 구축하여, 한반도의 자연환경 변천사를 파악하고, 기온온난화가 지속될 때 한라산 고산경관과 생태계가 당면할 문제를 파악하고 대안을 제시하는데 필요한 정보를 제공할 것으로 기대된다.

The morphological variations and habitat environment of the Zostera asiatica Miki (Zosteraceae) were examined in the waters off the eastern coast of Korea and Akkeshi Bay of Japan. In this study, we report new habitat of Z. asiatica along the eastern coast of south Korea； Gonghunjin, Donghori, Youngdong and Chilpo. Z. asiatica is found at the depth of 8∼15 m in these areas. However, Z. asiatica grows at the depth of 3 m in Akkeshi Bay of Japan. The sediment of habitats in the eastern coast of Korea were principally composed of sand. The stems were 64.0∼75.7 cm long in mature plants with flowering shoots and the leaves were 11.0∼15.0 mm wide for Korean populations. Plants from Akkeshi Bay of Japan had stems of 187.0∼234.0 cm in length. The difference in size are considered to be due to the depth of habitats. In spite of the significant morphological difference between Korea and Japan population of Z. asiatica, there was no difference in ITS sequences.

The distribution of cryophilous arctic-alpine and alpine plants in Korea is reviewed in connection with palaeoenvironment, along with a discussion to their origins, patterns of migration, and their refugia. At present, the estimated number of Korean arctic-alpine and alpine species is 419, and this includes 75 arctic-alpine species, 239 alpine species and 105 Korean endemic alpine species. The disjunctive distribution of cryophilous arctic-alpine and alpine plants is likely to be due to first, the downslope and southward expansion of those species towards the Korean peninsula as a primary refugia from the arctic region as the Pleistocene glacial phases approached, and then their subsequent isolation upslope in mountain areas toward a secondary refugia as the interglacial and post-glacial climatic ameliorations followed; secondly, the expansion of forest tree communities on lowland and montane areas subsequent to the end of the Pleistocene has had the effect of dividing formerly high mountains as a result of the increased competition; and thirdly, the general disapperance or restriction of available habitats for arctic-alpine and alpine species because of post-glacial climatic amelioration. The existence of 139 alpine species exclusively in the north of Korea may be due to the following reasons; first, frequent exchanges of alpine floras with other neighbouring East Asian regions would have been facilitated; secondly, there are numerous high mountains available for the alpine plants to survive and prosper during the post-glacial period; thirdly, the existence of easy accesses between mountains within the north, which has enabled alpine floras to migrate when necessary; and finally, the availability of diverse environments and habitats for the alpine flora of the north. However, the continued survival of those species in Korea at the world's or East Asia's southernmost limits of their distribution for many species is in danger if global warming associated with the greenhouse effect takes place.

During the systematic study of the genus Bidens L. (Asteraceae) in Korea, we found two specimens collected from Bujeon Plateau, Hamgyungnam-do, which are recognized as a new taxon (B. radiata Thill. var. radiata) for the flora of Korea. The Korean name for this taxon is newly designated as 'Sam-ip-gu-wa-ga-mak-sa-ri'. The close relative of this taxon is B. radiata Thill. var. pinnatifida (Turcz. ex DC.) Kitam., but B. radiata var. radiata can be distinguished from B. radiata var. pinnatifida by having mostly 3-parted and lanceolate lobe of leaf. The key for varieties of B. radiata is given.

This study examined the techniques of creating gardens overseas using native plants from the Korean peninsula, focusing on the case of 'Das Dritte Land', an art garden created in Berlin, Germany. While Korean garden artists are recognized worldwide and are planning to globalize Korean gardens, the purpose of this study is to share information so that Korean gardeners can expand their activities and rediscover the utilization and value of plants native to the Korean peninsula. The work began as part of a project to mark the 30th anniversary of the collapse of the Berlin Wall. To realize the landscape of Korea with the motif of Inwang Jesaekdo, the geographical shape of the Baekdu-Daegan trail was reproduced with black stone, and the naturalization of Korean peninsula species was utilized in the creation of a garden Berlin. It is a surreal bio-top utopia that blooms with the bio-groups of the Korean peninsula. This study examined the process of plant survey analysis, transportation and stabilization, planting planning, composition and monitoring, and targeting the self-growth of the Korean peninsula, which is a symbol of harmony between the South and the North. The planting of Korea's native plants in overseas gardens symbolizes the uniting of the ecosystems on the Korean peninsula. The process of the Korean peninsula's young plants taking root, flowering, and spreading along Germany's previously divided border metaphorically conveys the desire for the unification of the Korean peninsula. In addition, various art programs in the garden space suggest a foundation for cultural dialogue and communication between the two Koreas. Moreover, creating gardens overseas implies that the cooperation of plant research institutes plays an important role in the transfer of plants and the maintenance of life, while the advancement of Korean gardens overseas plays an essential role in the spread of garden culture in our country.

서리이끼속(Racomitrium Brid.)은 고깔바위이끼과(Grimmiaceae)에 속하며 전 세계에 약 80여종이 알려져 있다. 이 중 한국산 서리이끼속은 18종이 보고되어 있으며, 그 중 6종은 1900년대 초반 한반도에서 최초 발견되어 신종으로 보고되었다. 서리이끼속 이끼류는 주로 양지바른 바위나 사질토양 등에 서식하고, 건조에 강한 것으로 알려져 있다. 원예·조경 분야에서 실내 벽면 및 옥상 녹화용 자원식물로 서리이끼속은 주로 늦은서리이끼(Racomitrium japonicum)와 모래이끼(Racomitrium canescens)가 활용되고 있다. 국내에서도 자원식물로써 선태류에 대한 관심이 증대함에 따라 자생 선태류에 대한 형태적 특징과 함께 생육환경에 대한 정보 제공 요구 또한 증가하고 있다. 이에, 본 연구는 자원식물로 활용이 가능한 한반도산 서리이끼속의 형태·생태적 특징을 파악하고자 하였으며, 기준표본 원산지가 한반도인 서리이끼속 6종을 우선하여 서식 환경 특징을 파악하고자 한다.

We report for the first time a taxon of the genus Thyrocarpus (Boraginaceae) from Daecheongdo, Ongin-gun, Incheon-si in Korea. This taxon appears to be Thyrocarpus glochidiatus Maxim., previously known from China. The new Korean name, 'Dae-Cheong-Ji-Chi', was given considering the name of discovered location. A description, an illustration and a photograph were given.

Most evergreen Quercus species are typical, dominant members of Korean evergreen forests. However, little is known about the distribution status of Q. myrsinifolia Blume there. To enhance our knowledge about their natural range in Korea, we conducted field surveys based on specimen records and an extensive literature search. We also determined their exact number as a first step in planning their conservation. The results indicated that these trees are strictly limited to Jin Island, and 169 mature individuals were the maximum number and occurred in only three subpopulations on that island. Previous misidentifications and perhaps mislabeled locations for plant specimens were the main reasons for earlier confusion about distribution. We believe that these results can provide guidance when making specific recommendations for management interventions. These discoveries also demonstrate the value in having reliable information about plant specimens in general. We also speculated about what makes this species particularly vulnerable to local extinction.
