Abstract:To investigate the effect of different temperatures on digestive enzyme activities in Phrynocephalus forsythii and Eremias multiocellata, the amylase activity (iodine-starch colorimetry), lipase activity (turbidimetry) and trypsin activity (ultraviolet absorption method)in the liver, stomach and duodenum samples of P. forsythii and E. multiocellata under different temperatures were assayed, respectively. The results showed that in the temperature range of 4-45 ℃, the digestive enzyme activities increased first and then decreased with temperature increasing. At 40 ℃, the activities of amylase, lipase and trypsin in the liver, stomach and duodenum of P. forsythii reached the highest level, while the temperature for the highest enzyme activities of E. multiocellata was 35 ℃. These results suggested that the digestive enzyme activities of P. forsythii and E. multiocellata were related with temperature and this relationship also involved the physical states of lizards at different temperatures. Moreover, these findings revealed that the acclimation temperatures of the 2 lizards were significantly different when digestive enzyme activities were maximal, and these were accordant to the preferred temperature of the 2 lizards.
