    Description
    Observations on the Indian Spiny-tailed Lizard Saara hardwickii (Gray, 1827) were undertaken in Tal Chhapar Wildlife Sanctuary, Rajasthan, India during the monsoons (July) following quadrat sampling that was time-constrained. The study revealed that the area is one of the preferable habitats for the species. A population analysis showed that the relative abundance of the subadults was higher, followed by juveniles and adults during the study period. The beginning of activity of the lizards was found to vary over the study period depending on prevailing weather conditions. The activity pattern was bimodal, except across rain events. The study revealed two important ecological findings about these lizards; complete sealing of burrow during rains which differed from partial sealing on normal days and complete diurnal cycle of body colour changes during the monsoon. Feeding was the predominant activity of this lizard followed by basking, resting and chasing each other. The adult lizards were found to be strictly herbivorous, in spite of an abundance of insects available in the area during the period. Subadults and juveniles were found to eat both plant parts, as well as insects. Microhabitat use such as inside grass clumps was found to be higher followed by barren ground, under shade and on stones.

    Food habits and temporal activity patterns of the Golden Jackal Canis aureus and the Jungle Cat Felis chaos in Pench Tiger Reserve, Madhya Pradesh
    Type
    Journal Article
    Description
    The food habits and temporal activity patterns of the Golden Jackal Canis aureus and the Jungle Cat Felis chaus were studied between January 2008 and June 2009 in Pench Tiger Reserve (PTR), Madhya Pradesh. A total of 50 jackal scats and 85 jungle cat scats were collected where-ever encountered in the study area. Information on activity pattern was obtained using camera traps. Fifty-two pair self-triggered analog cameras were deployed in each 2 x 2 km² across the study area (> 250 km²) close to animal trails which were set to work on a continuous 24 hour period. Rodents contributed maximum in the diet of these two species (65% golden jackal scats and 56% jungle cat scats). Eight thousand five hundred and sixty camera-trap nights revealed 189 jungle cat captures and 49 golden jackal captures. The activity of golden jackal had a more homogeneous distribution in time. Present study showed that although some degree of overlap is observed between the two sympatric species, an overall difference in dietary composition and activity patterns enabled them to coexist in PTR.
