Habitat use by sympatric small carnivore in Sariska Tiger Reserve, Rajasthan, India.

Abstract

The present study on three sympatric carnivores, two felids: jungle cat (Felis chaus), and caracal (Caracal caracal) and one canid, the golden jackal (Canis aureus) aimed at studying their spatio - temporal use of food resources. The hypothesis are as follows : 1) Jungle cat is relatively more eclectic in the kind of habitat it inhabits than the jackal. 2) The felids are mostly nocturnal whereas the jackal is both diurnal and nocturnal ( cathemeral). 3) Diet of the three carnivores differs between seasons. 4) Small mammals «1 kg. body weight) form the major diet of the felids and are taken in proportion to their abundance. 5) Jungle cat and caracal are dietary specialists relative to the jackal. The study was conducted in Sariska Tiger Reserve (STR) which is located between 74° 17' to 76° 34'N and 25° 5' to 27° 33' E. STR encompassing an area of BOO km2 has three core areas of which core 1, with an area of 273.B km2 forms. the proposed National Park. This area functioned as the study site and the intensive study area was approximately 30 km2.
