【摘要】 2003~2004年在黑龙江省完达山林区,根据野外啃食痕迹调查,对马鹿冬季食性进行了研究。结果表明,榆、紫椴、榛、暴马丁香、杨、黄檗是马鹿主要的冬季食物(44. 31%、10. 07%、7. 60%、7. 17%、6. 56%、6. 38% ),组成马鹿冬季大宗食物。马鹿对榆、核桃楸、龙牙楤木、紫椴、毛接骨木、黄檗、水曲柳、狗枣猕猴桃、柳、托盘、疣枝卫矛表现出正选择。杨、榛和暴马丁香虽然是马鹿的主要食物,但相对于它们较高的可获得性而言,马鹿对它们表现出负选择。更多还原

【Abstract】 From 2003 to 2004, food-habits of red deer in winter were studied by field browse survey in Wanda Mountain. The results suggested that Ulmus propinqua, Tilia amurensis, Corylus mandshurica, Syringa amurensis, Populus spp., Phellodendron amurense made up of the majority of red deer winter food, accounting for 44.31%, 10.07%, 7.60%, 7.17%, 6.56%, and 6.38%, respectively. Red deer showed a positive selectivity for Ulmus propinqua, Juglans mandshurica, Arialia mandshurica, Tilia amurensis, Sambucus buergeriana, Phellodendron amurense, Fraxinus mandshurica, Actinidia kolomiktad, Salix spp., Evonymus pauciflorus, Rubus crataegifolius. Considering high availability, those plants of Populus spp., Corylus mandshurica, Syringa amurensis were the major winter food of red deer, but red deer showed a negative selectivity for them.更多还原
