  • This study aimed to provide fundamental data for enlargement strategy of Ramsar site through the analysis of designation properties about 22 sites which has been registered for 20 years since Yongneup (Mt. Daeam) was designated as the first Ramsar site in Korea. Designation properties were analyzed on the basis of Ramsar Information Sheet and ecological properties was mainly analyzed in relation to designation criteria. Designation of Ramsar wetland was concentrated before and after Changwon Congress in 2008 and in terms of area 11 sites are below $1km^2$ and 5 sites are above $10km^2$. The average number of applied designation criteria was 2.86 and Criterion 2 (threaten species), Criterion 1 (representativeness and rareness of wetland type) and Criterion 3 (biodiversity) are mainly applied. In terms of protection species, internationally recognized species were 18 species on IUCN redlist, 12 species on CITES and 13 species on CMS, and nationally recognized species were 76 species on endangered species designated by Ministry of Envirionment, 83 speceis on national redlist and 71 speceis on endemic species respectively.

  • The remarkable economic growth achieved in the modern era has revitalized various industries, including pet trade. More than 2,000 species of non-native species have been introduced to South Korea and approximately 7.7 tonnes of alien turtles are imported annually. Turtles belonging to the family Kinosternidae. They are mostly small and popular pets, although they are designated as Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) species. In the present study, we present the first two species of musk turtles found in the wild in South Korea. On April 5, 2023 and July 8, 2023, an eastern musk turtle (Sternotherus odoratus) and a razorbacked musk turtle (Sternotherus carinatus) were captured in Ilsandong-gu, Goyang-si, Gyeonggi-do and Jung-gu, Daejeon, respectively. The carapace length was 88.6 mm for S. odoratus and 105.68 mm for S. carinatus. They were identified based on their morphological characteristics and mtDNA cytochrome b gene. These turtles were found in waterfront areas with over 1.4 million annual visitors. Both sites were found to have threatened amphibians and reptiles. There is an urgent need to continue monitoring and conducting risk assessments for the protection of endemic species in Korea.

  • A new fungus isolated from the leaves of Eleutharrhena macrocarpa in southern Yunnan, China is described using morphological and molecular evidence. Phylogenetic trees based on the combined nuclear ribosomal DNA internal transcribed spacer (ITS), translation elongation factor-1α (TEF1), and β-tubulin gene (TUB2) sequences showed that Diaporthe eleutharrhenae sp. nov. is sister to Diaporthe chinensis N.I. de Silva, Lumyong & K.D. Hyde and morphologically differs in shorter alpha conidia (5-8.5× 1.5-2 ㎛) and the presence of beta conidia. This study also resolves a nomenclatural problem, as two taxa were published using the same name. To avoid confusion, the unrelated D. chinensis H. Dong, J. W. Xia & X. G. Zhang is here renamed as D. dongii (H. Dong, J. W. Xia & X. G. Zhang) S. J. Song & Landrein, sp. nov. in honor of the author that described this species. Study and description of fungi associated with threatened tropical species could help to understand their ecology as well as the potential spread of fungi onto cultivated crop species.

  • The genus Gueldenstaedtia Fisch. is small genus of Fabaceae that includes four species worldwide. Among these, G. monophylla Fisch and G. verna (Georgi) Boriss. are currently recognized as occurring in Mongolia. Here, we present our findings on G. verna from our recent field surveys in eastern Mongolia in 2020. Gueldenstaedtia monophylla is mostly distributed in the western region, whereas G. verna occurs in eastern Mongolia. The regional conservation status of both species was assessed as near threatened based on criterion B in the country. We provided descriptions, grid distribution maps, taxonomic notes and photographic illustrations of the two species based on our newly collected samples.

  • Flora and distribution of vascular plants included introduced species of Mt. Nam park in Seoul were investigated from 1997 to 1998. The flora was composed of 112 families, 338 genera, 487 species, 1 subspecies, 60 varieties, 11 forma or 559 taca. Whole taxa of Mt. Nam calculated with the other reports were recorded 125 families, 461 genera, 832 species, 2 subspecies, 115 varieties, 14 forma or 963 taxa. Mt. nam area has lost its properties because of road and promenade construction, several park reclaimation, introduction of foreign species and exotic plants, and so on. The urbanized index (UI) was comparatively high at 18.3%. Eupatorium rugosum which shown high shade tolerance comparatively was occupied dominantly in road sides. The natural ecosystem and biodiversity of Mt. Nam were under threatened by introduced species. DBH mode of Pinus densiflora community was shown bell shape but that of Quercus mongolica was shown reverse J shape, therefore, it will be occupied in the future this area dominantly by Q. mongolica community. However the vegetation of Mt. nam park area are repressing by superior position in their growth of introduced species included R. pseudo-acacia, Ailanthus altissima and E. rugosum, etc.

  • Background: The southern and eastern parts of the Gobi Desert area are a unique dry ecosystem with a diverse regional desert, semi-desert, and mountain dry steppe flora. This area habitat is located at the overlap of different floristic regions; on its northeast side, Central Asian desert flora is dominating, and on the eastern side, East Asian flora is observed. The comprehensive survey was carried out to find the floral diversity of the medicinal plants on the region. Methods: All recorded species in this study were based on the collected voucher specimens between June and August in the year 2017. Results: We recorded 23 families, 57 genera, and 78 species of vascular plants. The families Asteraceae (15 species), Fabaceae (10 species), and Amaranthaceae (10 species) were represented most in the study area, while Caragana (5 species), Salsola (4 species), and Arnebia (3 species) were the most common genera found. Conclusion: Conservation status for remarkable species was also reviewed based on the literature. Around the study area, 24 species as "sub-endemic," 10 species as "very rare," 4 species as "rare," 1 species as "alien," 13 species as "relict," 10 species as "Red Book," 2 species as "endangered (EN)," 3 species as "vulnerable (VU)," 3 species as "near threatened (NT)," and 2 species as "least concern (LC)" plants are growing.

  • The Oriental White Stork (Ciconia boyciana) and the Crested Ibis (Nipponia nippon) are wetland species listed as "Endangered" on the IUCN Red List of Threatened Species. The two species were once common on the Korean peninsula, but have experienced a severe population reduction in the past decades. Currently, they are officially extinct in Korea. At present, reintroduction programs to release the birds to the wild are in progress in Korea as well as in Japan. In this study, we surveyed the historic breeding sites of the two species using the literature and face-to-face interviews with local people as a step toward determining appropriate breeding habitats for reintroduction. We found 26 historic breeding sites for the Oriental White Stork in Chungcheong-do and Gyeonggi-do, but did not find any breeding sites for the Crested Ibis. These findings suggest that the Oriental White Stork was resident, while the Crested Ibis was a winter visitor to Korea. Based on these results, we discuss the possibilities for successful reintroduction of the two species in Korea.

  • Many models intending to explain the latitudinal gradient of increasing species diversity from the poles to the equator are presented, which are a formalisation of the species-energy hypothesis. The model predictions are consistent with patterns of increasing species number with increasing mean air or water temperatures for plants and animals. An increase in species richness is also correlated with net primary production or the Normalised Difference Vegetation Index. This implies that increased availability of resources favours increased diversity capacity. The explanatory variables included in the biodiversity prediction models represent measures of water, energy, water-energy, habitat, history/evolution and biological responses. Water variables tend to be the best predictors when the geographic scope of the data is restricted to tropical and subtropical areas, whereas water-energy variables dominate when colder areas are included. In major models, about 20-35% of species in the various global regions (European, Africa, etc.) will disappear from each grid cell by 2050 and >50% could be vulnerable or threatened by 2080. This study provides good explanations for predictive models and future changes in biodiversity depending on various scenarios.
