In July 2006, the diurnal activity rhythms of 13 heads of captive Qinling golden takin were observed in Shaanxi Provincial Centre for the Breeding and Conservation of Rare Wildlife at daylight (from 9:00 am to 4:00 pm in July). The behavioral ethnogram was identified through observation at the sampling site, with the behaviors of golden takin recorded at 5 min interval using instantaneous scannable sampling method.

Among them,Spermophilus dauricus was diurnal animal,and a long activity interval for avoiding strong sunlight at noon was observed.Microtus maximowiczii was active all day along,and its activity intensity by day and by night was similar,which may be a result of its adaptation to the habitat and feeding environment.

结果表明，达乌尔黄鼠为昼行性鼠种，中午时段出现明显的活动间歇期以避开强烈的日晒；莫氏田鼠为昼夜活动型鼠种，日夜活动强度差异不显著，与其生活于草滩底部营食草根的生活方式相适应。

The results showed that glucose and fructose are primary soluble sugars from night to 10: 00 a.m. in mature leaves, but during 13: 00 - 16: 00 p.m., stachyose becomes the most abundant oligosaccharide, this diurnal change is mostly due to the tempestuous fluctuation of stachyose concentration in mature leaves. During photoassimilate transportation, the p rimary soluble sugar in phloem sap is stachyose. When transportation is finished, sucrose becomes the main sugar in phloem sap. Cucumber leavesmay store photoassimilate in the forms of starch, glucose, fructose, stachyose and sucrose at night. The concentrations of glucose, fructose and stachyose in phloem sap are much lower than in leaves at that time. There may be some unique mechanisms modulating source-sink translocation by which soluble sugars in leaveswere prevented from loading into the phloem further during night.

结果表明夜间至上午10： 00，葡萄糖和果糖是叶片中主要的可溶性糖，而下午13： 00至16： 00，水苏糖成为成熟叶片中含量最高的可溶性糖，这种变化主要由叶片中水苏糖含量剧烈的昼夜变化引起；当黄瓜同化物从源叶向外运输时，韧皮部汁液中的可溶性糖以水苏糖为主，运输完毕后则以蔗糖为主；黄瓜成熟叶片在夜间以淀粉、葡萄糖、果糖、水苏糖、蔗糖等各种形式贮藏尚未运出的同化物，而此时韧皮部汁液中葡萄糖、果糖、水苏糖的含量极低，可能有特定的源库调节机制阻止叶片中的可溶性糖在夜间进一步向韧皮部中装载。
