A 17-month-old intact male Djungarian hamster (Phodopus sungorus) was presented with an axillary mass. Fine needle aspiration cytology of the mass showed a malignant epithelial cell tumor. Histopathological examination of the surgically removed mass confirmed a complex apocrine gland adenocarcinoma. Twenty days postoperatively, the mass recurred in the same area, and the patient died while waiting for the second surgical removal. This is the first report of the cytology, histopathology, and postoperative recurrence of apocrine gland adenocarcinoma in a Djungarian hamster.

This study analyzed research trends in the field of ecological research. Data were collected based on a keyword search of the SCI, SSCI, and A&HCI databases from January 2002 to September 2022. The seven keywords, including biodiversity, ecology, ecotourism, species, climate change, ecosystem, restoration, wildlife, were recommended by ecological research experts. Word clouds were created for each of the searched keywords, and topic map analysis was performed. Topic map analysis using biodiversity, climate change, ecology, ecosystem, and restoration each generated 10 topics; topic maps analysis using the ecotourism keyword generated 5 topics; and topic map analysis using the wildlife keyword generated 4 topics. Each topic contained six keywords.

Background: Traditional wildlife monitoring has often relied on invasive techniques posing risks to species and demanding substantial resources. To address this, camera traps emerged as non-invasive alternatives, albeit primarily tailored for larger mammals, posing limitations for small mammal research. Thus, the Mostela, an innovative tool designed to overcome these challenges, was introduced to monitor small mammals in South Korea. Results: The Mostela was deployed at two study sites in South Korea, yielding compelling evidence of its efficiency in capturing small mammal species. By analyzing the collected data, we calculated the relative abundance of each species and elucidated their activity patterns. Conclusions: In summary, the Mostela system demonstrates substantial potential for advancing small mammal monitoring, offering valuable insights into diversity, community dynamics, activity patterns, and habitat preferences. Its application extends to the detection of endangered and rare species, further contributing to wildlife conservation efforts in South Korea. Consequently, the Mostela system stands as a valuable addition to the toolkit of conservationists and researchers, fostering ethical and non-invasive research practices while advancing our understanding of small mammal populations and ecosystems.

Constructed wetland was built for industrial factory wastewater treatment with environmentally sound method from July to October, 2000. Ultimately this case study was carried out to conserve water quality of river and underground water and to provide wildlife habitat and rest place for people in the industrial area. The size of constructed wetland was 10m$\times$6m (upper area) with a treatment capacity of 2.5㎥ per day. It was supplied with wastewater 0.625㎥ at intervals of six hours. Vertical flow system was chosen to promote efficiency. Draining layer was built one meter in soil depth out of sand mixed with pebbles in a ratio of two to one. Perennial emergent plants, Phragmites communis, Typha orientalis, Juncus effusus, Iris pseudoacorus, 20 individuals per square meter were planted. In the aspect of reusing, eco-pond was created for increasing biological species diversity and also deck and information signboard were established for the education of environment. As the result of monitoring, it was revealed that the constructed wetland was effective in removal of BOD$_{5}$, COD, T-N, T-P and has being gradually improved as a wildlife habitat(biotope).

Construction of highway would influence wildlife habitat being fragmented and deteriorated. It is inevitable to observe the death of animals that are killed by vehicles. Nonetheless the cause and status of animal roadkill have not been studied, and this study first attempted to analyze the roadkill in major highway in Korea. We collected 860 individuals of dead animals in Joongang Highway during 1996-2003. Among them Korean hare(Lepus sinensis) was totaled in 165 individuals(19.2%) with the highest figure; Korean racoon dog(Nyctereutes procyonoides) was 146(17.0%); Korean squirrel(Sciurus vulgaris) 56(6.5%); Korean roe deer(Capreolus capreolus) 26(3.0%). Domestic animals was totaled in 232 individuals(27.0%); domestic dog(Canis familiairis) 25, and domestic cat(Catus felis) 207. This study also categorized habitat as mountain-mountain, mountain-plain, mountain-river, plain-plain, plain-river, river-river in each side of the road. Habitat of mountain-plain was the heightest with 296(38.9%) individuals followed by mountain-mountain with 263(34.6%). This indicates that wild animals associated with mountain habitat was most influenced by the construction of roads. This study implied that we should mitigate the roadkill by designing artificial construction such as eco-bridge, fences along the sideway, and boxes under the highway, underdrain structure, etc. The monitoring and cause of habitat fragmentation with GIS approach should be followed to reduce the roadkill.
