Abstract	Two types of acorns (fresh, current-year acorns and old, previous-year acorns) of Quercus liaotungensis were used under two different situations (night and day) to examine the removal and predation by animals in the field. The acorns disappeared very fast. During the day, all of the 280 ‘this-year’ acorns (TA) and all of the 140 ‘last-year’ acorns (LA) were removed by animals within 6 h and 5 h, respectively, after acorns were put in place. At night, all of the 280 TA acorns were removed by animals within 10 h after acorns were distributed, and 71 out of 140 LA acorns were removed within 10 h. Animals consumed a small proportion of acorns in situ (11.8%). The number of TA acorns consumed in situ at night was higher than that during the day. During the day, the number of LA acorns consumed in situ was significantly higher than TA acorns. This result suggests that the most important harvesters of Q. liaotungensis during the day were visually orientated diurnal animals, and the most important harvesters at night were olfactorily orientated nocturnal animals. Furthermore, the latter are more efficient than the former at finding and harvesting acorns, because they spend less energy on harvesting the same number of sound acorns.
