    A Countryside carnivore: aspect of leopard ecology at Jawai, Rajasthan
    (Wildlife Institute of India, Dehradun, 2017) Sharma, Ravi Kumar; Qureshi, Qamar; Das, Abhijit
    1.Increasing human population and habitat fragmentation has impacted the large carnivore population across India. Leopard among pantherine is more tolerant to human disturbance and co-occur with humans in the wide variety of habitats. 2. Study was undertaken to understand status of leopard and factors responsible for its survival in human-dominated landscape. 3. Study was conducted in Jawai Dam Community Conservation Reserve from December 2016 to April 2017 in a semi-arid region of Pali, Rajasthan, India We examined villager's perception towards leopard by taking out the percentage of each response of respondents. Tolerance and religious view toward leopards was found significantly similar with each other, villagers has higher economic losses (livestock loss by leopards) than benefits (tourism activities) generated by hotel lobby. Villagers were examined to have minimal loss of human life and injuries by leopards, so it's easy to say about existence than co-existence or co-occurrence of both leopard and human in Proposed lawai Leopard Community Conservation Reserve.

    A Whistle Amongst Growls : Dholes in a Multi Predator System in Dry Deciduous Forests of India
    (Wildlife Institute of India, Dehradun, 2015) Ghaskadbi, Pallavi; Habib, Bilal; Qureshi, Qamar
    A significant amount of research has proved that there is a positive correlation between habitat heterogeneity/diversity and animal 'species diversity owing to the availability of more exploitable niches (Tews et al. 2004). On a spatial scale for free ranging large carnivores, a place like the Tadoba- Andhari Tiger Reserve has a low habitat heterogeneity, however, it shows a variety of species of both predators and prey in a small area. Studying the prey- predator interactions in such a system would lead to a better insight into large carnivore ecology. In contrast with the African Wild dog which enjoys much more attention of researchers and biologists, the Dhole has clearly not been a favourite. Being a social carnivore, there is a complex and dynamic fission and fusion of packs amongst Dholes. However, there is a grave lack of information on the pack dynamics of the Dhole. I attempted to conduct experiments to study one of the fundamental factors of social behaviour which is individual recognition.

    Food habits of tiger (Panthera tigris tigris) in Sariska tiger reserve, Rajasthan
    (Wildlife Institute of India, Dehradun, 2003) Avinandan, D.; Sankar, K.; Qureshi, Qamar
    The present study aims at understanding relationship between tiger and its prey in a semi arid tract. The study was conducted in Sariska tiger reserve, Rajasthan over a period of six months from November 2002 to April 2003. Density estimation of major wild and domestic prey species was done to assess availability to tigers in terms of density and biomass. The line transect method was used to estimation prey density

    Habitat Occupancy by tiger Prey Species Across Anthropogenic Disturbance Regimes in Panna National Park, M.P.
    (Wildlife Institute of India, Dehradun, 1999) Mathai, Manu Verghese; Chundawat, R.S; Qureshi, Qamar
    Effect of anthropogenic disturbance on habitat occupancy by tiger prey species was studied in Panna National Park, Madhya Pradesh. The study was conducted between November 1998 and April 1999. Line transect method and Pellet count technique were used to estimate abundance for all ungulates. Abundance estimates were used as a measure for intensity of habitat use by all species. The density estimates from line transects are associated with high coefficient of variation, which is largely a function of the small sample size resulting form extremely low densities. Ordination of habitat parameters grouped the transects based on habitat quality and structure, disturbance and topography. Anthropogenic disturbance was found to be an important factor, influencing habitat quality and differential use of habitats by animals. Sambar associated strongly with low disturbance hill habitats and poorly with relocated village sites and disturbed plateau transects. Indications from line transects and pellet count method concur in the case of sambar. Chital were very localised in their distribution being strongly restricted to secondary successional stages and ecotones between relocated village sites and woodland. Nilgai was a generalist in terms of habitat occupancy. In case of nilgai the two methods complement each other with the information they provide. The information from pellet-group counts was found to reflecting patterns that are not detected by direct sampling methods like line transects. Chinkara was strongly associated with the disturbed areas, largely because of its openness, but also found in the undisturbed areas. Wild pig, like nilgai, was a generalist, but showed preference for fringe areas of forest adjoining agricultural fields. Langur showed a marked preference for hill habitats and did not differentiate between disturbed and undisturbed hill habitats. Langur also showed the strongest association with water. The distribution of preferred prey, sambar and chital is localized. Nilgai, which is distributed throughout the study area, is found in habitats not favorable for tigers. Such a distribution would probably only support dispersing and transient animals. Therefore habitat management should be aimed at maintaining and expanding habitats suitable for cervids. Disturbance in the form of livestock grazing and woodcutting are largely responsible for maintaining poor habitat quality. The cause for these disturbances cannot be disconnected from the socio-economic and cultural reality of the people, both near and far, and therefore the conservation of the tiger has to address these aspects rather than restricting only to the biology of the animal.

    Environmental Influences on Space Utilisation and the Activity Budget of Captive Leopards (Panthera pardus fusca) in Five Zoos in Southern India
    (Wildlife Institute of India, Dehradun, 1999) Mallapur, Avanti; Chellam, Ravi; Qureshi, Qamar
    A behavioural study was conducted on leopards in five zoos situated in Thiruvananthapuram, Chennai, Mysore and Bangalore between November 1998 and March 1999. Twenty six leopards were studied in five zoos of which sixteen were singly housed and ten were housed in groups. There were 16 males and 10 females. Only three of the 26 animals were captive born, 10 were captive reared and 13 were wild caught. Fourteen singly housed leopards were studied in on-exhibit and off exhibit enclosures on days with visitor presence and also on zoo holidays, two singly housed leopards were studied in the off-exhibit enclosures only. The group of ten at Bannerghatta Zoological Gardens, Bangalore was studied only in the on exhibit enclosure. Scan sampling method was used to record the behavioural patterns in leopards. The ethogram, which consists of all behaviour observed in five zoos lists 12 behavioural states and 29 behavioural events. The leopard enclosures were divided into imaginary blocks and the utilisation of these grids by the leopard was recorded alongwith behaviour at five-minute intervals. . Each leopard was studied for two days on-exhibit. two days off-exhibit and one zoo holiday. The leopard at Childrens' Park. Guindy was also studied for two excess visitor days during the Pongal festival. Information on each leopard was obtained from zoo records. No significant difference in behaviour was observed between males and females. and wild caught and captive-reared individuals. The behavioural repertoire of female leopards was significantly associated with their period of anoestrus. Stereotypic pacing was found to increase with enclosure size. Leopards housed in larger enclosures exhibited higher levels of activity and stereotypy behaviour. Smaller enclosures housed leopards that rested for longer proportions of time. Activity and resting behaviour peaks in the daily activity budget of the leopards were due to their crepuscular nature. The peaks in stereotypic behaviour in the daily activity budget were influenced by zookeepers' presence. Food-anticipatory behaviour was observed in all leopards before and during feed time. Individuals that were studied on-exhibit and off-exhibit exhibited higher levels of stereotypic behaviour off-exhibit and higher levels of activity behaviour on-exhibit. The presence of visitors also influences the behaviour repertoire of captive leopards. All singly housed leopards studied on days with visitor presence and zoo holidays exhibited higher levels of activity on zoo holidays and higher levels of resting behaviour on days with the presence of visitors. Six individuals were studied singly and then as pairs. The proportion of activity and resting behaviour exhibited when they were housed in pairs was higher and stereotypic behaviour, though not statistically significant, was lower than when they were singly housed. The utilisation of space differed between singly and group-housed leopards. Singly housed individuals utilised the "edge" and "back" zones of their enclosures more and the sructurally "enrich" zone less than group-housed leopards. Most of the leopards utilised the "edges" of their enclosure for stereotyping. the "back" zone for resting and the "rest" of the enclosure for activity behaviour. The structural features found within the enclosures that housed leopards were of two categories; sleeping platforms. trees and sheds that stimulated resting behaviour and logs. snags and tree trunks that stimulated activity behaviour. In enclosures that were structurally enriched with sleeping platforms, sheds or trees, leopards utilised the "enrich" zone of the enclosure for resting instead of the "back" zone. Enclosures having logs and snags. the "enrich" zones is utilised to exhibit activity behaviour. The utilisation of the structurally enriched zones of the enclosures was positively correlated with enclosure complexity. Leopards in structurally enriched enclosures exhibited higher levels of activity and lower levels of resting than the barren enclosures The factors that were found to influence the behavioural repertoire of captive leopards have been taken into consideration while recommending environmental enrichment techniques for the renovations of old enclosures and the construction of new ones.
