  • The water deer, Hydropotes inermis (Cervidae), is native to China and Korea and has two subspecies of the Chinese water deer (Hydropotes inermis inermis) and Korean water deer (Hydropotes inermis argyropus). To date, only the Korean water deer has been reported in South Korea. In this study, however, an intraspecific phylogeny and haplotype analysis based on mitochondrial cytochrome oxidase I indicated that both Korean and Chinese water deer are found in South Korea. The populations of the two Korean genetic lineages did not show distinct geographic distributions. Further morphological studies on the Korean water deer will be required to confirm its taxonomic status.

  • Susceptibility to chronic wasting disease (CWD) in cervid species has been associated with polymorphisms in the prion protein gene (PRNP). The single nucleotide polymorphisms (SNPs) were found in the PRNP of the Korean subspecies of Chinese water deer via analyses of the DNA sequences obtained from 34 individual deer. Two SNPs were detected at codons 77 and 100. One SNP at codon 77 encoding Glycine was determined to be a silent mutation but the other SNP detected at codon 100 induced an amino acid change, from Asparagine to Serine. The prion protein (PrP) amino acid sequence of the water deer showed 98.8-99.2% homology with those of American elk, white-tailed deer and mule deer. The PrP of the water deer contained amino acid residues closely related with CWD-susceptibility. This study is the first to describe genetic variations in the PRNP of the Korean subspecies of Chinese water deer.

  • Infections of Toxoplasma gondii and Babesia microti are reported in many wild animals worldwide, but information on their incidence and molecular detection in Korean wild fields is limited. In this study, the prevalence of T. gondii and B. microti infection in blood samples of 5 animal species (37 Chinese water deer, 23 raccoon dogs, 6 roe deer, 1 wild boar, and 3 Eurasian badgers) was examined during 2008-2009 in Gangwon-do (Province), the Republic of Korea (=Korea) by using serological and molecular tests. The overall seropositivity of T. gondii was 8.6% (6/70); 10.8% in Chinese water deer, 4.3% in raccoon dogs, and 16.7% in roe deer. PCR revealed only 1 case of T. gondii infection in Chinese water deer, and phylogenic analysis showed that the positive isolate was practically identical to the highly pathogenetic strain type I. In B. microti PCR, the positive rate was 5.7% (4/70), including 2 Chinese water deer and 2 Eurasian badgers. Phylogenetic analysis results of 18S rRNA and the ${\beta}$-tubulin gene showed that all positive isolates were US-type B. microti. To our knowledge, this is the first report of B. microti detected in Chinese water deer and Eurasian badger from Korea. These results indicate a potentially high prevalence of T. gondii and B. microti in wild animals of Gangwon-do, Korea. Furthermore, Chinese water deer might act as a reservoir for parasite infections of domestic animals.

  • The water deer (Hydropotes inermis) is one of the most primitive extant deer of the family Cervidae. Unlike Chinese water deer, Korean water deer have rarely been studied, even though they have relatively well remained in Korea. In particular, the home range of the Korean water deer has not yet been studied. Here we estimated the home range of the Korean water deer using two different methods (GPS and radio tracking) and analyzed the home range according to sex, time, and season. The mean home range size of four individuals was 2.77 $km^2$ and 0.34 $km^2$ under the 95% minimum convex polygon (MCP) and the 50% kernel (K) method, respectively. There seemed to be a difference in home range size between males (3.30 $km^2$) and females (2.25 $km^2$) under the 95% MCP method. We also found a difference in home range size between day (1.90 $km^2$) and night (2.43 $km^2$) by 95% MCP method. In addition, a home range size difference was observed between summer (4.65 $km^2$) and spring (0.48 $km^2$) or fall (0.85 $km^2$) using the 95% MCP method. Water deer seemed to have a larger home range in night than in day, and males also have a larger home range. We presumed that the GPS tracking method of the code division multiple access system could be a very useful tool for understanding the ecology of the water deer using the radio tracking method. Using these tracking methods and through future research, we can better understand the habitat use pattern of these water deer.

  • The sacrum fused with ilium in a chinese water deer (Hydropotes inermis) was observed. The sacrum consists of four sacral vertebrae which was fused each other. In the ventral part of the fused pelvis, on the left, there was a 20.19 mm gap at the dorsolateral part of the sacroiliac articular part which is in between the promontory and the cranial border of the first ventral sacral foramen. On the right, there was a 14.34 mm gap at the dorsal part of sacroiliac articulation. In the dorsal view of the fused pelvis, the wing of sacrum and the wing of ilium were fused tightly, so that the boundary of the two bones was not recognizable. The left and right second dorsal sacral foramina and the third dorsal sacral foramen on the left were small. The third dorsal and ventral sacral foramina on the right were not formed.

  • This report describes the first prize design of Midongsan Eco-park, which is located in Chungcheongbuk-do (North Chungcheong) province. Criteria of the winning design are as follows: 1) The design should include a neighborhood park as well as a portion of a green zone, in order to harmonize the area ecosystem, gradually assimilate the surroundings, and serve as an education tool for the public. 2) According to an analysis of area maps and a site-inspection, a preserved area, a buffer area, a restored area, and a developed area should be developed. In the buffer and restored areas, major facilities and activity spaces should be set up. 3) Observation trails should be accessible to visitors, and a variety of adventure programs should be available. 4) The eco-park should be designed to provide a habitat for the Gorani (Chinese water deer) which used to live around Midongsan. 5) For sensuous and vivid visitor experiences, diverse programs are to be designed to accommodate different seasons, visitor ages, and required time. Environment and eco-education are to be emphasized to maximize the effect of the eco-programs. 6) Optimal activities for visitors of different ages, optimal time intervals and eco-programs by age are also suggested. 7) Facilities are zoned into three sections according to level of development. Each section has a main area and supplementary areas for better understanding. 8) Nature-friendly arrangement of facilities and construction should minimize earthwork and adverse effects on the local ecology. Throughout the planning, the following things were learned: longer-term analysis including all season's observation is essential; planning, designing, bui Iding and managing should be based on this careful, extended observation. The contest should have taken plate over a longer period of time in order enable more detailed planing of the eco-park For improved management and activities, a volunteer system in linked with schools eco-institutions and NGOs should be developed with eco-interpreters.

  • Water is an important component in the production of fresh produce. It is mainly used for irrigation and application of pesticides and fertilizers. Several outbreaks cases related to fresh produce have been reported and water has been identified as the most likely source. On the other hand, wildlife has been identified as a possible source of the waterborne pathogens. The purpose of this study was to investigate the effect of wildlife access on irrigation water used in the cultivation of Chinese cabbage in Goesan. The frequency of wild animals access to upstream water source and the contamination level of bacteria such as Escherichia coli and Enterococci of irrigation water used in Chinese cabbage farm was examined. A total of 37 wildlife including the wild bear and water deer were observed in upstream of water source during the cultivation of Chinese cabbage. The result indicated the presence of hygienic indicator bacteria from the upstream where there is no human access. The contamination range of coliforms, E. coli, and Enterococcus spp. Detected in the irrigation water were 2.13~4.32 log MPN / 100 mL, 0.26~2.03 log MPN / 100 mL, and 1.43~3.49 log MPN / 100 mL, respectively. Due to low water temperatures, the contamination levels of coliform bacteria and E. coli in the irrigation water during harvesting time was lower compared to those recorded during transplanting of Chinese cabbage. However, no significant difference was detected in the number of Enterococci during the cultivation of Chinese cabbage. The results indicated the need to manage the microbial risk in irrigation water to enhance safety in cultivation of Chinese cabbage.

  • The aim of this study was to investigate food culture represented by the grain yard, water well, kitchen, and meat storage space which were depicted in the mural painting of An-Ak tomb No. 3. The mural paintings of An-Ak tomb No. 3 were compared with those of ancient Chinese tombs before the 4th century in order to understand their characteristics. Above all, the tomb murals describe the form and function of the stove (buttumak) as well as the cuisine using the cauldron (sot) and steamer (siru) in a very interesting manner. The meat storage space of An-Ak tomb No. 3 shows whole carcasses of animals such as roe deer, dog, and pig. However, Chinese murals show that while small animals such as soft-shelled turtle, fish, chicken, duck, pheasant, rabbit, etc. were stored as whole carcasses without being cut into pieces, large animals such as cows and pigs were slaughtered and each piece of their carcasses such as the head, thigh, meat loaf, and cardiopulmonary part was separately depicted. These tomb murals vividly describe the food culture of Koguryo and China before the 4th century.

  • This study investigated mammal fauna in the sabbatical area of Mt. Unmun, Kyungsangbuk-do from December, 2007 to September, 2009. A total of 24 species belonging to 11 Families, 6 Orders, were identified in the survey area. Dominant species were as follows: Chinese water deer (Hydropotes inermis), Siberian chipmunk (Tamias sibiricus), Korean mole (Mogera wogura), and East Asian field mouse (Apodemus peninsulae). Especially, four Legal Protection Species specified as National Monument (NM) and Endangered Species (ES) found in this survey were as follows: Flying squirrel (Petromys volans; NM #328 and ES level II), Eurasian otter (Lutra lutra; NM #330 and ES level I), Leopard cat (Prionailurus bengalensis; ES level II) and Marten (Martes flavigula; ES level II). These results on the geographical distribution of various mammal species and Legal Protection Species indicate that this area is a valuable ecosystem for native mammal species. On the other hand, many feral cats were also found and specified as a management species. The results of this study show that further long-term investigation and management plan are needed to protect against harmful species and maintain the native ecosystem of Mt. Unmun.
