Abstract

Time budget and activity rhythm of Chinese alligators (Alligator sinensis) during daytime had been studied in Hongxing Reservoir of Anhui Chinese Alligator National Reserve from May to June in 2004 .The results showed that the behaviors of Chinese alligators include swimming , basking , resting , bellowing , mating and so on . Among them, swimming , resting , basking and bellowing take up (34.30 26.27)%, (30.44 18.50)%, (21.0432.95)% and (14.1618.97)% of the diurnal activity percentages respectively .The percentages that swimming takes up in the different time period are close to each other , ranging between 26.47 % and 44.83 %(2=6.906 5 , P =0.227 7 , df =5), but Chinese alligators usually don't keep a sort of poses in the course of swimming .Two peaks are characteristic of resting behavior , ranging from 9 :00 to 11 :00 and from 17 :00 to 19 :00 respectively .Basking comes forth and has only a peak between 11 :00 and 13 :00 after 3 June .Two bellowing peaks observed are from 7 :00 to 9 :00 and from 21 :00 to 23 :00 . Bellowing is related to the difference of water temperature (DWT).Chinese alligators frequently bellow when DWT is between 1.5 ℃ and 3.5 ℃, and the biggest bellowing times take place at 3.5 ℃.It is suggested that the behaviors of Chinese alligators are mainly affected by their reproductive factor in the rutting season .[ Ch , 3 fig .36 ref .]
