Two specific hypotheses that availability of high quality food, predation and interspecific competition have independent and addictive effects on population system dynamics for microtine small mammals; and that availability of high quality food could reduce home range and aggressive behavior level between individuals of microtine small mammals, predation and interspecific competition have independent effects on spatial behavior of microtine small mammals were generally supported by the results in this study.
研究结果检验了本项研究提出的特定假设:高质量食物可利用性,捕食及种间竞争对田鼠类小型哺乳动物种群系统动态具有独立的和累加的效应;高质量食物可利用性能降低田鼠类小型哺乳动物的攻击行为和巢区,捕食与种间竞争能减少田鼠类小型哺乳动物的活动。

Winter,because of cold and food resource was shortage,animal to get more nutrition material andenergy,to adopt the changes of environment condition,to prolong alimentary canal andincrease food in alimentary canal detention time,to be able to absorb the nutrition materialdigestion countermeasure in food fully.As availability and nutrition were rich such as insummer and fall,however,shortening the length of alimentary canal,make food inalimentary canal current velocity accelerate,since make animal absorb in the season withabundant food the more nutrition material energy that is plenty of with accumulation.9adopt relative fatness,body chemical composition,kidney fatty index and marrow fattyindex 4 kinds of population nutrition condition assessment technique appraise as squirrelnutrition condition of population.
冬季,由于寒冷和食物资源匮缺,动物为了获取更多的营养物质和能量,采用延长消化道、增加食物在消化道内滞留时间,从而能充分吸收食物中的营养物质的消化对策,来适应外境环境条件的变化;在食物可利用性大、食物中营养物质较丰富的季节,则缩短消化道长度,使食物在消化道内的流速加快,从使动物在食物充裕的季节能摄取更多的营养物质和积累大量的能量。9采用肥满度、身体组成成分分析、肾脂肪指数和骨髓脂肪指数四种种群营养状况评价方法对松鼠种群的营养状况进行了评价。

This paper from squirrel food availability,food composition,the selectivity of foodresource,take edible behavior and energy countermeasure for food nutrition quality and theform structural feature of alimentary canal and few aspect such as seasonal adaptabilitychange as well as nutrition condition appraisement of population carry out research as redsquirrel nutritional adaptive strategy.At the same time for go on preliminary discuss thegenetic diversity of red squirrels from Daxingan Mountain,Xiaoxingan Mountain,respectively.The result was considered:1squirrel forage plant can use existent obviousseasonal change.
本论文从松鼠食物的可利用性、食物组成、对食物资源的选择性、食物营养质量、取食行为和能量对策、消化道形态结构特征及季节适应性变化以及种群营养状况评价等几方面对东北松鼠营养适应对策进行了研究,同时对大、小兴安岭两个地区松鼠种群的遗传多样性进行了初步的探讨,结果认为:1松鼠饲料植物的可利用性存在明显的季节变化。
