  • Recent conditions in North Sulawesi Province (NSP) have become favorable for the development of tourism. In this paper, we present the recent status of biodiversity and tourism in NSP as a basic consideration towards integrative biodiversity conservation strategy. Overall, biological accounts suggest that NSP is important for the world biodiversity conservation program. NSP's biodiversity makes the area a major nature-based tourism (ecotourism) site in the world. Development of diverse tourism programs in NSP has provided new opportunities for balancing development and conservation of regional ecosystems. However, the excessive tourism growth in some particular areas in NSP has been identified as the primary factor of environmental degradation. Nowadays, biodiversity of North Sulawesi regions are suffering from the number of tourist impacts and facilities. Based on those conditions, tourism planning and development in NSP is needed to formulate a proper strategy to protect the ecosystem and biodiversity from degradation and extinction. This will be a new challenge of sustainable island tourism development and biodiversity conservation in NSP.

  • Tofieldia ulleungensis, a new species of the genus Tofieldia from the Nari Basin on Ulleungdo Island, Korea, is described and illustrated. The new species is similar to T. yoshiiana var. koreana in terms of the plant height and in that it has having a long raceme, whitish tepals, and whitish stigma, but can be readily distinguished from the latter by the presence of 1-2 linear cauline leaves, a slightly bent leaf apex, basal leaves which are twice as wide, a shorter pedicel, a revolute style, and crescent-shaped seeds.

  • In 2009, United Nations Educational, Scientific and Cultural Organization (UNESCO) recognized the unique outstanding ecosystem biodiversity and distinct ecocultural values of the Shinan Dadohae Biosphere Reserve in the island region. The Dadohae area, which has been sustainably conserved for scores of years, boasts not only a unique ecosystem, but also has residents with a wide range of traditional ecological knowledge. In terms of understanding the soundness of the ecosystem network known as the landscape system, the recent expansion of environmental development has served to heighten the degree of consideration given not only to biodiversity, which has long been used as an indicator to assess ecosystem soundness, but also to assess cultural diversity. Man has used the surrounding landscape and living organisms as his life resources since the beginning. Moreover, whenever necessary, man has developed new species through cultivation. Biodiversity became a foundation that facilitated establishing cultural diversity such as food and housing. Such ecological knowledge has been conveyed not only to adjacent regions, but also at the international level. The recent rapid changes in the Dadohae area island ecosystem caused by the transformation of fishing grounds by such factors as climate change, excess human activities, and marine pollution, is an epoch event in environmental history that shows that the balance between man and nature has become skewed. Furthermore, this issue has moved beyond the biodiversity and landscape diversity level to become an issue that should be addressed at the cultural diversity level. To this end, the time has come to pay close attention to this issue.

  • Herbal medicines have been used as a basic means of clinical trial throughout history, and traditional medicines are targeted to seek functional components. To discover new cosmetic or food ingredients among numerous natural resources from Jeju island, we screened for inhibition activity against nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Although NO formation plays an important role to relax vascular muscles or eliminate tumors, NO produced excessively in inflammatory condition can cause metabolic diseases or inflammatory dysfunctions. Among 52 natural resources ethanol extracts, 5 extracts inhibited NO production over 25% compared to only LPS-treated control at the concentration of $100{\mu}g/mL$. In further study, we try to investigate other bio-activities and the phytochemicals of 5 different extracts as useful ingredients for cosmetics or functional foods.

  • A eukaryotic marine microalga was isolated from Jungmun Saekdal Beach, Jeju Island, Korea and an integrated approach, including molecular phylogeny and morphology, was used to determine its taxonomical status. Molecular phylogenetic evidence inferred from the small subunit (SSU) 18S rRNA sequence and internal transcribed spacer (ITS) secondary structure analysis clearly showed that the isolate belonged to the recently described species, Jaagichlorella roystonensis. Distinctive morphological keys of the species were also observed by light microscopy and scanning/transmission electron microscopy(S/TEM). In this study, a Korean marine J. roystonensis species was described for the first time and was subsequently added to the national culture collections in Korea.

  • We surveyed the biodiversity of lepidopterous insects in Jindo Island using UV bucket trap in July 2016 to determine the relationship between surrounding environment and ecosystem in order to contribute to biodiversity conservation and management of coastal islands in Korea. Based on our survey results, a total of 262 lepidopterous insect species in 16 families were collected from Jindo Island. Members belonging to families Noctuidae and Geometridae made up approximately half of the total species (86 species [32.82%] in Noctuidae and 44 species [16.79] in Geometridae). There were 29 species (11.07%) belonging to Crambidae and 28 species (10.69%) belonging to Pyralidae. As a result of all collections based on previous literature and this study, a total of 730 species belonging to 34 families were collected from Jindo Island, including 33 protected species, 242 species (33.15%) belonging to Noctuidae (the most abundant), 124 species (16.99%) belonging to Geometridae, 79 species (10.82%) belonging to Crambidae, and 65 species (8.90%) belonging to Pyralidae. The most frequently collected species was Lamoria glaucalis in this syudy. Our results on the diversity of lepidopterous insects will provide basic information for future investigation on diverse changes in the ecosystem of Jindo Island, Korea.
