The project aims to analyze the Influences of Biotic and Abiotic components on the activity patterns of Smooth-coated Otters (Lutrogale perspicillata) using Camera Traps. To answer this, Cuddeback and Foxelli Camera traps were used for monitoring otter activities as a time of activity, and purpose of visit. Camera traps were positioned at active dens of 5 otters in Cauvery River, Karnataka in the period from May to July 2019. The activity was also measured via direct sightings of otters. The behavior of a group or single otter was observed and recorded.
To assess the activity pattern of Smooth-coated otters inside Holts (Dens)
To assess if any biotic and abiotic components influence the activity pattern of otters
The group of Smooth-coated otters was mostly active during crepuscular and night which was about 50 % and 28.57 % respectively. The nocturnal activity of otters appeared to be associated with the necessity to Defecate and Scent marks with approximately 21.42 % and 7.14 % respectively and also increased anthropogenic pressure during diurnal times. This study emphasizes the need to consider the impacts caused by the change in biotic and abiotic factors on the activity of otters. The study also provides a Conservation Action Plan with possible solutions that aim to minimize the threat to the otter population.
