  • We report a new distribution of Sedum kiangnanense D. Q. Wang & Z. F. Wu on the Korean Peninsula. This species was first reported in China and is distributed in Anhui and Zhejiang provinces. We found this species on Hongdo Island in Heuksan-myeon, Shinan-gun, Jeollanam-do in the Republic of Korea. S. kiangnanense is well distinguished from other species in Korea by 4- or 5-verticillate leaves on the sterile stems and a spatulate leaf shape. We provide its morphological description, detailed illustrations, and a key to related taxa. We have given this species a new Korean name, Ip-kkot-dol-na-mul, which means flower-like leaved sedum.

  • The present study was performed to elucidate the distribution of protozoans according to the actual conditions of soil pollution around Ulsan industrial complexes, Korea. Samples were collected from the top-soils of 13 localities in eight times during the period from 16 April 1994 to 14 January 1995. As a result of this study, total 11 species of hypotrichous ciliated protozoa were identified and analyzed. These hypotrichs are 6 species of stichotrichine hyporichs ( Keronopsis sp., Pseudourostyla sp., Hoiriiticha syivatica, Hipiosticha multistylata, Hoios-ticha sp. and ParuroleFitus sp.) and 5 species of sporadotrichine hypotrichs (Oxyricha sp., Steinla sp., Histriculus cavicola, Hemisincirra sp. and Gonostomum auiili). Of these 11 species, 4 species (Keronopsis sp., Pseudourostyla sp., Holosticha sp. and Hemisincirra sp.) are reriorted for 1%e first time from Korea. All the sampling localities could be grouped in three zones by the cluster analysis with the abundance and distribution of protozoans. This result is approximately coincide with the ionation by the concentration of heavy metals.

  • According to the energy hypothesis, the energy input per unit area primarily determines species richness in regions of roughly equal area. Some energy-related ecological research included identification of major climatic variables to determine regional species richness. In this study, the local butterfly species richness was examined to find out whether weather variables affected the local distribution or abundance of butterfly populations. Butterfly monitoring data from May 2001 to April 2002 taken at Mt. Yudal, Mokpo, in the southwestern part of Korea, and six weather variables (monthly mean values of temperature, precipitation, evaporation, wind speed, air pressure, and sunlight) were analyzed. Multiple regression analysis showed that only temperature explained 80% and 70% of the variability of log-transformed number of species and individuals, respectively, indicating that temperature played an important role in local species richness. Furthermore, global warming could affect the abundance and distribution of butterflies regionally as well as locally.

  • This study is based on crane fly specimens collected more than 80 years ago in 1938-1939 and preserved at the United States National Museum, Smithsonian Institution, Washington DC, USA. Despite many attempts with a variety of methods, no additional specimens of this genus were captured. This likely means that that this genus is extinct on the Korean Peninsula, or its distribution is restricted to the northern areas of the Democratic People's Republic of Korea (North Korea). The genus Prionolabis Osten Sacken, 1860 with four species, one of them Prionolabis dis(Alexander, 1950) endemic to North Korea, was recorded by Ch. P. Alexander (Alexander, 1938, 1940, 1950). All succeeding papers listing these species were based on these original works without study based on actual specimens. For each species, we present general information on genus, redescriptions of species based on Korean specimens, illustrations of important taxonomical structures, elevation range, period of activity, habitat information, general distribution, and a distribution map for the Korean Peninsula.

  • The climate is changing rapidly, and this may pose a major threat to global biodiversity. One of the most distinctive consequences of climate change is the poleward and/or upward shift of species distribution ranges associated with increasing temperatures, resulting in a change of species composition and community structure in the forest ecosystems. The Baekdudaegan mountain range connects most forests from the lowland to the subalpine zone in South Korea and is therefore recognized as one of the most important biodiversity hotspots. This study was conducted to understand the distribution range of vascular plants along elevational gradients through field surveys in the six national parks of the Baekdudaegan mountain range. We identified the upper and lower distribution limits of a total of 873 taxa of vascular plants with 117 families, 418 genera, 793 species, 14 subspecies, 62 varieties, two forms, and two hybrids. A total of 12 conifers were recorded along the elevational gradient. The distribution ranges of Abies koreana, Picea jezoensis, Pinus pumila, and Thuja koraiensis were limited to over 1000 m above sea level. We also identified 21 broad-leaved trees in the subalpine zone. A total of 45 Korean endemic plant species were observed, and of these, 15 taxa (including Aconitum chiisanense and Hanabusaya asiatica) showed a narrow distribution range in the subalpine zone. Our study provides valuable information on the current elevational distribution ranges of vascular plants in the six national parks of South Korea, which could serve as a baseline for vertical shifts under future climate change.

  • Background: Citizen science is becoming a mainstream approach of baseline data collection to monitor biodiversity and climate change. Dragonflies (Odonata) have been ranked as the highest priority group in biodiversity monitoring for global warming. Ischnura senegalensis Rambur has been designated a biological indicator of climate change and is being monitored by the citizen science project "Korean Biodiversity Observation Network." This study has been performed to understand changes in the distribution range of I. senegalensis in response to climate change using citizen science data in South Korea. Results: We constructed a dataset of 397 distribution records for I. senegalensis, ranging from 1980 to 2020. The number of records sharply increased over time and space, and in particular, citizen science monitoring data accounted for the greatest proportion (58.7%) and covered the widest geographical range. This species was only distributed in the southern provinces until 2010 but was recorded in the higher latitudes such as Gangwon-do, Incheon, Seoul, and Gyeonggi-do (max. Paju-si, 37.70° latitude) by 2020. A species distribution model showed that the annual mean temperature (Bio1; 63.2%) and the maximum temperature of the warmest month (Bio5; 16.7%) were the most critical factors influencing its distribution. Future climate change scenarios have predicted an increase in suitable habitats for this species. Conclusions: This study is the first to show the northward expansion in the distribution range of I. senegalensis in response to climate warming in South Korea over the past 40 years. In particular, citizen science was crucial in supplying critical baseline data to detect the distribution change toward higher latitudes. Our results provide new insights on the value of citizen science as a tool for detecting the impact of climate change on ecosystems in South Korea.

  • The influx of marine exotic and alien species is disrupting marine ecosystems and aquaculture. Herdmania momus, reported as an invasive species, is distributed all along the coast of Jeju Island and has been confirmed to be distributed and spread to Busan. The potential habitats and distribution of H. momus were estimated using the maximum entropy (MaxEnt) model, quantum geographic information system (QGIS), and Bio-ocean rasters for analysis of climate and environment(Bio-ORACLE), which can predict the distribution and spread based only on species occurrence data using species distribution model (SDM). Temperature and salinity were selected as environmental variables based on previous literature. Additionally, two different representative concentration pathway (RCP) scenarios (RCP 4.5 and RCP 8.5) were set up to estimate future and potential habitats owing to climate change. The prediction of potential habitats and distribution for H. momus using MaxEnt confirmed maximum temperature as the highest contributor(77.1%), and mean salinity, the lowest (0%). And the potential habitats and distribution of H. momus were the highest on Jeju Island, and no potential habitat or distribution was seen in the Yellow Sea. Different RCP scenarios showed that at RCP 4.5, H. momus would be distributed along the coast of Jeju Island in the year 2050 and that the distribution would expand to parts of the Korea Strait by the year 2100. RCP 8.5, the distribution in 2050 is predicted to be similar to that at RCP 4.5; however, by 2100, the distribution is predicted to expand to parts of the Korea Strait and the East Sea. This study can be utilized as basic data to effectively control the ecological injuries by H. momus by predicting its spread and distribution both at present and in the future.

  • 본 연구는 대표적인 아고산식물인 동일속 식물 구상나무와 분비나무의 기후변화 민감성 평가에 목적이 있다. 이를 위해 종 분포 모형을 이용하여 현재 및 미래의 종 분포 확률을 예측하였고 기후변화 민감성 평가를 하였다. MTSS를 기준으로 예측된 잠재 분포지는 분비나무가 구상나무보다 감소율이 많았으며, 스칼라 민감도를 이용한 평가에서는 구상나무의 민감도가 분비나무보다 높았다. 본 연구와 같은 종 분포 모형을 이용한 연구에서는 위치자료 및 환경변수에 따라 종 분포 확률이 달라질 수 있으므로 연구 대상종의 생태 환경에 대한 면밀한 조사가 선결되어야 하며, 본 연구를 기초로 하여 국내에 적용 가능한 기후변화민감성 평가 방법이 개발된다면 기후변화와 생물 다양성 적응 정책의 중요한 의사결정 수단이 될 것으로 기대한다.
