|Abstract:||The present study compared the community structure of reptiles in a forest fragment to that of a continuous forest. The study was carried out in the Vythiri section of South Wayanad Forest Division from June second week to September second week 2015. Diurnal quadrats, transects and time constrained searches were carried out to describe the species assemblage. In total 80 person hours was spend in the continuous forest and 70 person hours was spend in the forest fragment for sampling. Species accumulation curves were plotted and diversity indices were evaluated for both sites. Eight species and forty nine individuals were sampled from the continuous forest while from the fragment merely three individuals belonging to two species were found. Eutropis macularia (n = 18) was the most abundant species in the forest followed by Calotes ellioti (n = 9). Cnemaspis aff. monticola was the only shared species in the forest and forest fragment from quadrats and transects. Twelve different habitat variables were measured from the sampling sites and five of the variables differed significantly with respect to the study sites. Correlation analysis revealed that canopy cover (-0.44) has a negative correlation and leaf litter depth (0.41) have a positive correlation with abundance of reptiles in the forest. None of the habitat variables correlated with abundance in the fragment. The long isolation, small area and edge effects might have resulted in the local extinction of many of the herpetofauna in the fragment.|
