On clinical examination animal having embedded in still mesh ( Fig 1) to his upper one third body part and due to which dorsal primary layer, muscles were torn off. 3. Surgical Intervention and Treatment According to situation decision was made to go for surgical removal of mesh. Animal was prepared for surgery by administration of sedation with Ketamine. After sedation mesh was cut off with cutter.

But in the present study due to unavailability of inhalant anesthetics after a thorough discussion combination of anesthetics was used. Nasir et al. (2016) used diazepam @ 0.2 mg/kg body weight by intramuscular route as preanaesthetic and ketamine @ 10 mg/kg body weight by intramuscular route as a main anaesthetic agent. Sedation was maintained by ketamine @ 5 mg/kg body weight during surgical procedure of Lower Jaw in Indian Rock Python. Fig 3: Recovered wound after 25 th day In the present case muscle was sutured with simple interrupted suture and skin with horizontal mattress. Holz (2007) suggested an everting pattern of suturing for skin, such as a horizontal mattress suture, as skin tends to invert when cut. Animal takes 25 to 30 days for complete recovery of wound. This was in accordance with Holz (2007), described healing of the wounds for four to six weeks after surgery, preferably after a shed. Fig 2: Wound site 5. Conclusion The present study concluded that in case of unavailability of inhalant anesthesia, Diazepam and Ketamine combination can be used for anesthesia in surgical management of rat snake.

    REPTILIA Order OPHIDIA (Snakes) I. Family COLUBRIDAE Ahaetulla prasina Green Vine Snake This snake was found in Renah Kayu Embun and Napal Licin survey sites at elevation 1400 meters asl and 300 meters asl respectively. Usually it can be seen in degraded habitat including plantation, secondary growth and house compounds, to primary rain forest (Inger and Stuebing, 2005; Kurniati, 2003). It occurs from lowlands up to mountain forests over 1500 meters asl (Kurniati et al., 2001; Kurniati, 2003). It is common species at low elevation (Inger and Stuebing, 2005), but become rare at high elevation such as Renah Kayu Embun survey site. This species is known from South-east Asia, East Indies (Sulawesi and The Lesser Sunda) (Stuebing and Inger, 1999: de Lang and Vogel, 2005). Figure 91. A. prasina (Photograph by H. Kurniati). Amphiesma sp This undescribed snake was found in Muara Labuh survey site at elevation 800 meters asl. It was a nocturnal snake that inhabited strong moving stream bank. The morphology of this snake is similar to A. kerinciense (David and Das, 2003). Possibly, it is a new species, but future study is needed. Figure 92. Amphiesma sp from Muara Labuh (Photograph by H.

It inhabited lowland primary rain forest. It occurs at elevation between sea level to 1200 meters asl (Kurniati, 2003), but it is confined to be lowland. In Tapan survey site, it was rarely observed.

  • Human-Snake Conflict Patterns in a Dense Urban-Forest Mosaic Landscape
    Herpetological Conservation and Biology 14(1):143–154. Submitted: 9 June 2018; Accepted: 25 February 2019; Published: 30 April 2019. HUMAN-SNAKE CONFLICT PATTERNS IN A DENSE URBAN-FOREST MOSAIC LANDSCAPE SAM YUE1,3, TIMOTHY C. BONEBRAKE1, AND LUKE GIBSON2 1School of Biological Sciences, University of Hong Kong, Pokfulam, Hong Kong, China 2School of Environmental Science and Engineering, Southern University of Science and Technology, Shenzhen, China 3Corresponding author, e-mail: [email protected] Abstract.—Human expansion and urbanization have caused an escalation in human-wildlife conflicts worldwide. Of particular concern are human-snake conflicts (HSC), which result in over five million reported cases of snakebite annually and significant medical costs. There is an urgent need to understand HSC to mitigate such incidents, especially in Asia, which holds the highest HSC frequency in the world and the highest projected urbanization rate, though knowledge of HSC patterns is currently lacking. Here, we examined the relationships between season, weather, and habitat type on HSC incidents since 2002 in Hong Kong, China, which contains a mixed landscape of forest, dense urban areas, and habitats across a range of human disturbance and forest succession. HSC frequency peaked in the autumn and spring, likely due to increased activity before and after winter brumation. There were no considerable differences between incidents involving venomous and non-venomous species. Dense urban areas had low HSC, likely due to its inhospitable environment for snakes, while forest cover had no discernible influence on HSC. We found that disturbed or lower quality habitats such as shrubland or areas with minimal vegetation had the highest HSC, likely because such areas contain intermediate densities of snakes and humans, and intermediate levels of disturbance.
