Diet of the Common Palm hermaphroditus in a rural habitat in Kerala, India, and its possible role in seed dispersal

Abstract P. S. JOTHISH

Paradoxurus hermaphroditus

Common Palm Civet diet in a rural habitat in India was studied by faecal analysis. Observations were made from January 2008 to May 2010, although no faeces wereCarica found papaya after January was the 2010. most In common total 94 fruitfaeces of werewhich collected. remains Of these, vegetable matter alone was found in 82% and matter alone in 4%; 14% held both plant and animal matter. Fruits were the predominant vegetable matter in the faeces. Papaya were found and was eaten year round. No seasonal change in proportion or dietary shift between vegetable and animal matter- was observed. Seeds from faeces were viable and a high percentage of defecated seeds germinated. Considering the movement pattern of Common Palm studied elsewhere and the high seed germination rate, Common Palm Civet is plausibly an ef fective seed disperser of fleshy-fruited plants in the study area. Common Palm Civet often attacks poultry and is perceived as a Keywordsthreat by the poultry farmers.
