摘      要：Difference in environmental condition shapes variation in digestive tract length in evolutionary *** particular,environmental difference results in variation in food resource among different habitats,and thereby affecting energy intake and energy *** digestive theory predicts that animals foraging high indigestible materials of stomach contents can promote the increased gut ***,we studied variation in digestive tract and gut length across six Hylarana guentheri populations at different altitudes and latitudes to test the prediction of the digestive *** found that altitude and latitude did not affect variation in relative size of digestive tract and gut among *** also found that relative size of digestive tract and gut did not be correlated with diversity of prey items,but negatively correlated with proportion of digestible *** findings suggest that individuals foraging less digestible materials display relatively longer digestive tract than individuals foraging more digestible materials.
