The Tsushima leopard cat, Prionailurus bengalensis euptilurus, a small felid, inhabits only the Tsushima Islands in Japan. Previous studies of the Tsushima leopard cat revealed that natural factors; including sex, reproductive activity, season, and prey distribution and abundance affect leopard cat home range variation and habitat use. In this study, we focused on clarifying how anthropogenic factors influenced home range variation and habitat use of a male Tsushima leopard cat living near a suburban area in January, March, May and September 2005 using radio-tracking. The home range size (100% MCP) of this cat was $0.78\;{\pm}\;0.26\;km^2$ (mean ${\pm}$ SD, n = 4 tracking sessions) across the whole study period. However, the cat did not use all parts of its home range uniformly; rather it used some habitat types selectively. The cat avoided agriculture areas and residential areas in all of the tracking-sessions. On the other hand, the cat showed a weak preference for artificial structures and a strong preference for baiting sites in January and March, while it avoided them in May, and no baiting site was included in its home range in September. These results suggest that anthropogenic factors influenced the ranging patterns and habitat use of the leopard cat living near a suburban area. Artificial structures might provided good resting spaces for the cat in bad weather. When the density of its main prey was low in the winter, the cat tended to rely on artificial prey and had a small home range size.

This study shows the badge system for military officials of Joseon dynasty. The badge system for military officials of the 15th century consists of rank badges with tiger and leopard for the first and second ranks and rank badges with bear for the third rank. According to the code of laws, military officials are supposed to wear the rank badges with four different kinds of animals in Joseon dynasty. However, the badge system shown in the code of laws sometimes does not match with the badges in practices. Based on the literature, remaining badges and the badges in portraits, six different kinds of badges with animals are found : First, rank badges with tiger and leopard were used until the late 16th century. Second, rank badges with tiger were found in the period between the early 17th century and the latter 18th century. Third, rank badges with Haechi were found in the early 17th century. Fourth, rank badges with lions can be found in remains of the mid 17th century, the literature and the portrait of the late 18th century. Finally, the rank badges with double leopards or with single leopard were found from a portrait dated the late of 18th century to the last period of Joseon dynasty.

Because of the potential negative influence on their hosts, ecto-parasites are of prime importance to numerous species. Ticks are among these, distributed worldwide, and potentially transmitting diseases while sucking blood of diverse hosts. The leopard cat (Prionailurus bengalensis euptilura Elliot, 1871) is the only felid left in the Republic of Korea following widespread anthropogenic disturbances that have resulted in the extinction of both Panthera species: the Siberian tiger(Panthera tigris altaica Temminck, 1844) and Amur leopard (P. pardus orientalis(Schlegel, 1857)). This study identifies ticks collected from a roadkill leopard cat retrieved in Seosan area in the Republic of Korea. Two ticks attached to the facial area of the carcass were identified as Japanese hard ticks, Ixodes nipponensis, based on mitochondrial cytochrome oxidase I. The matching sample was from Japan with 99.7% similarities, and the only available sequence on GenBank. This study reconfirms that I. nipponensis parasitizes the endangered leopard cat P. bengalensis euptilura.

An aged (14 years old) female snow leopard exhibited renal calculi and pyelonephritis at necropsy. The animal experienced appetite loss, mild diarrhea, polydipsia, and difficulty breathing, and was curled up and staggering on its hind legs 2 days before death. Large calculi were found obstructing both sides of the renal pelvis. The left-side calculus was larger than that of the right side. These calculi had rough surfaces and were $15{\times}21mm$ and $9{\times}14mm$, respectively. The bladder was filled with dark, cloudy urine. Multiple ulcerous lesions were found in the inner layer of the bladder. Enterococcus faecalis and Proteus mirabili were identified via microbiological examination of the urine. Under microscopic examination, urine struvites were observed in the pyuria sediment in the bladder. To our knowledge, this is the first documented case of nephrolithiasis in a captive snow leopard.

본 연구는 원격무선추적 자료를 바탕으로 우리나라의 농촌지역에 서식하는 삵의 행동권, 서식지 선택, 개체군 위협요인을 파악하고자 하였으며 3개체(수컷 2, 암컷 1)를 대상으로 한 연구결과는 다음과 같다. 첫째, 행동권은 평균 $2.64{\pm}1.99km^2$(K 95)와 $3.69{\pm}1.34km^2$(MCP 100)이었으며, 핵심공간은 평균 $0.64{\pm}0.47km^2$(K 50)를 나타냈고, 겨울철에 추적된 수컷의 행동권이 가장 넓었다($5.19km^2$, MCP 100). 둘째, Jacobs index에 기반을 둔 Johnson의 서식지 선택모형을 분석한 결과 삵은 2단계 선택(경관 내에서의 서식지 선택)에서 초지와 논을 선호하고 산림은 회피하는 반면에, 3단계 선택(행동권 내에서의 서식지 선택)에서는 하천변의 초지를 매우 선호하고 논을 회피하였다. 셋째, 로드킬은 삵의 심각한 개체군 위협요인으로 판단되며, 논의 토지피복 비율이 높고, 하천변에 도로가 존재하며, 산림이 마을 주위에만 소규모로 존재하는 지역에서는 삵의 개체군 유지가 매우 불안정할 수 있어 이러한 지역에 로드킬 대책과 하천변 초지보호 등의 노력이 보다 집중되어야 할 것이다.

Intercostal abdominal hernia in the 11th intercostal space was identified in a leopard cat. Although mild leukopenia was found in laboratory examinations, no remarkable abnormality was revealed in medical imaging. To investigate abdominal organs, diagnostic laparoscopy was performed after hernia repair. In laparoscopic view, closure of the herniation site and a lesion with whitish discoloration in the liver (left medial lobe) were observed. Subsequently, laparoscopic liver biopsy was performed against the affected hepatic tissue. Histologically, the sample was diagnosed as mild hepatic lipidosis. Laparoscopy is considered useful for abdominal visceral examination and liver biopsy in a leopard cat patient.

A 2.2 kg adult female Amur leopard cat (Prionailurus bengalensis) injured in a road accident was rescued. Severe abrasions on the left chin were washed daily with an antiseptic and silver sulfadiazine ointment was applied. Corneal edema of the oculus sinister (OS) was treated with ofloxacin and 5% sodium chloride eye drops. The skin wounds gradually improved, but the eye condition did not improve and the lens was also found to be detached. In addition, on the 6th day of hospitalization, melena was observed. On radiographic examination, foreign bodies in the stomach and a fracture of the sternum were confirmed. Subsequently, endoscopic removal of foreign bodies and enucleation of the OS using an electrothermal vessel sealer were performed sequentially over several days. However, corrective surgery of the fractured sternum was not carried out because a natural union of the fracture had occurred, which was found to be fairly stable. The patient completely recovered on the 83rd day and was successfully released into the wild on the 97th day, after two weeks of adaptation training in a natural environment. This report describes the rehabilitation of a wild Amur leopard cat injured in a road accident through a series of diagnostic and treatment steps until its eventual return to the wild and highlights some improvements needed in the process.

The objective of this study is to analyze habitat distribution on tiger, wolf, and leopard in Joseonwangjosilok. Nowaday, we only come to meet these kind of animals at the historical records because of haman-induced habitat encroachment. Historically, extinct animal became an object of game by people. So, we try to get distribution information for restoration on historical extinct animals. We made distribution map by constructing 402 counts on tiger(350), leopard(51) and wolf(1) recordsfrom 14th to Early 20th century for study. Analyzing historical materials, criteria for data analysis took into account objectivity, location information, accuracy for extinct animals. We carried out location identification of animals by using geocoding comparing with geographical name of the Joseon Dynasty period, topographic map of time under the rule of Japanese imperialism, present place name and historical materials. Database items are constructed 20 types for example appearance year of animal, population, location, damage, etc. As a result of analysis for appearance regions, tigers were recorded in capital area of higher density population intensively, and also were frequently seen at Daegu, Andong etc. Leopard and wolf were founded at regionally Gyeonggi-do and Jinju with limitation, relatively seen a few number. The reason of the appearance records like this, tiger prefer game of open and water-front area in near human residential area, there are lots of historical records such as 'Hosang'(mourning someone who killed by Tiger) and hunting. But leopard and wolf inhabit rocky area and dense forest, the reason why they made a few contact with human. Results of this are expect to be applicable restoration research for extinct animal by providing for populations, habitat environments and distribution information.
