    Has conservation gone to the dogs? : ecological aspects of free ranging dogs of the Thar
    (Wildlife Institute of India, Dehradun, 2017) Mohandas, Monisha S.; Jhala, Y.V.; Qureshi, Qamar; Dutta, Sutirtha
    One of the few mammals to have a near-global distribution, dogs (Canis familiaris) are an introduced mammalian predator. Dogs have contributed to 11 vertebrate extinctions and are a potential threat to 188 threatened species globally. This study investigates population sizes, ranging patterns, behavioural activity, and resource utilisation of free-ranging dogs in Thar landscape, Rajasthan. 2. Using double sampling framework, I calibrated effort-standardized counts (C) with mark-recapture based abundances (𝑁̂) that was used to estimate dog abundances within human habitation. Landscape-scale dog abundance was estimated using vehicle transect based distance sampling. Home ranges of nine free-ranging dogs was determined using locations from radio-telemetry. Resource use was quantified as feeding durations on various food items based on continuous monitoring. Resource availability was quantified as wild prey and livestock carcass density using line transect based distance sampling. This study provides information on important aspects of free-ranging dog ecology and their impacts in Thar landscape. It provides the basis required for implementing dog control programs in the landscape focusing on the flagship and critically endangered great Indian Bustard Ardeotis nigriceps.
