摘 要 ：马鹿和狍冬季取食的植物种类基本相同,但采食各种植物的比例明显不同。马鹿的主要食物为杨、桦、柳、紫椴,狍为桦、紫椴、杨,与抱相比,马鹿对木本植物有更强的选择性。马鹿对植物的选择性和植物中半纤维素的含量之间存在明显的负相关关系,而狍则不存在这种关系。马鹿食物中粗蛋白和酸性洗涤木质素的含量低于狍,可消化干物质的含量高于狍。两种动物食物生态位有一定重叠,马鹿食物生态位的宽度在整个冬季大于狍。狍在冬季可能通过不同于传统理论预测的途径来获取能量。

Abstract:Comparison of winter diets of red deer and roe deer showed that the plant species in winter diets of these two animal species were primarily similar, but the percentage of each plant species was significantly different. Principal foods of red deer and roe deer were composed of 4 plant species (Po-pulus spp., Salix spp. and Tilia amurensis) and 3 plant species (Betula spp., Tilia amurensis and Populus spp.) respectively. Red deer had strong solectivities to ligneous plants compared with roe deer. A significa...
