  • To analyze the behavioral characteristics of Korea endangered species female gorals (n=6) during the period of birth, using GPS collar attached on their necks, we carried out this study in two areas (Seoraksan and Woraksan National park) from March 2007 to May 2014. According to our analysis there was a change in their home range during the period of birth. The home range of females (n=6) in MCP 95% was Spring ($1.00{\pm}1.00km^2$) > Autumn ($0.66{\pm}0.30km^2$) > Summer ($0.61{\pm}0.40km^2$) > Winter ($0.50{\pm}0.10km^2$) (F=4.198, p<0.05). In the monthly analysis, their home ranges were dramatically reduced in May, June and July. It showed a statistically significant difference (F=24.261, p<0.01). These gorals showing a drastic change in home ranges were identified as gorals having offspring individual and their home ranges were decreased. The average altitude was $615.77{\pm}173.508m$ and there was no significant difference in major change between parous and nonparous female gorals. Through this analysis, we expect that it can be applied to the goral management and restoration project considering the time of birth.

  • Cypripedium japonicum is known to be the indigenous plant to Korea, Japan, and China. However, C. japonicum represents the most critically endangered plant species in South Korea. The plant is esthetically pleasing due to its flower, which is larger than any other orchidaceous species. Disease symptoms relating to gray mold were observed on C. japonicum in May 2019. The suspected pathogen was successfully isolated from the symptomatic leaf tissue and conducted a pure culture of the fungi. The conidia formed consisted of a colorless or light brown single cell, which was either egg or oval-shaped with a size of 7.1 to 13.4 × 5.2 to 8.6 ㎛. Molecular phylogenetic relationship analysis was also confirmed that the pathogen concerned belonging to the family of Botrytis cinerea. Therefore, the findings confirmed that the pathogen isolated from C. japonicum was consistent with the unique properties of B. cinerea.

  • This study was carried out to analyze the home ranges of three medium-sized mammals(Nyctereutes procyonoides, Prionailurus bengalensis, and Meles leucurus) inhabiting the Sobaeksan National Park, Korea. Three individuals of each species were captured using live traps(Tomahawk live trap 210A) and radio tracking was conducted from June 2012 to May 2014 using VHF and CDMA methods. We determined that the home range of N. procyonoides was $6.53{\pm}6.66km^2$(MCP 100), $3.39{\pm}4.73km^2$(FK 95), and $0.48{\pm}0.62km^2$(FK 50), that of P. bengalensis was $7.13{\pm}5.61km^2$(MCP 100), $7.77{\pm}3.91km^2$(FK 95), and $1.88{\pm}0.96km^2$(FK 50), and that of M. leucurus was $1.77{\pm}1.82km^2$(MCP 100), $3.17{\pm}4.52km^2$(FK 95), and $0.63{\pm}0.87km^2$(FK 50). The home ranges of both N. procyonoides and P. bengalensis were greater than that of M. leucurus, and moreover, both were larger than $6km^2$(P. bengalensis>N. procyonoides). The results also showed that for each species, 1.2~4.4% of the home range overlapped with that of the other two species and that this overlap occurred in the vicinity of a water system.
