贮脂类动物在冬眠前大量积累脂肪来准备冬眠,并在入眠时迅速降低体温和代谢率。为探究入眠准备期达乌尔黄鼠体温、代谢率、呼吸商及能量代谢的变化,将其入眠准备期分为育肥期、体重高峰期、育肥后期和冬眠前的试降期,使用植入式半导体温度记录元件iButton、开放式代谢仪和改进的代谢笼,监测其体温、代谢率及呼吸商和能量摄入的变化。结果显示:(1)达乌尔黄鼠体温在冬眠前13 - 34 d 开始下降,远早于冬眠但晚...
高原鼢鼠越冬食物选择与营养成分的关系
高原鼢鼠 营养成分 粮仓 选择指数
2016/7/19
为了解高原鼢鼠在越冬期的食物选择与营养成分之间的关系,采集了67 个高原鼢鼠的冬季粮仓及环境样方,分析高原鼢鼠对每一种植物的选择指数,将其分成3 种食物类型:喜食、可变和不喜食。通过测定每一种植物的粗蛋白、粗纤维、水溶性糖和粗灰分的含量,比较分析了营养成分含量在3 种食物类型间的差异,及其与各种植物选择指数的相关关系。结果显示,高原鼢鼠储存的食物种类多达67 种,本文选取含量较高且样本量大于5 的...

贮存温度和时间对大熊猫粪便样品皮质醇浓度的影响
大熊猫 非损伤性取样 粪便皮质醇 温度
2016/7/19
通过非损伤性取样比如粪便样品监测野生动物受胁迫的水平已成为一个重要的手段,然而针对从野外采集的样品,其运输和贮存温度条件是否干扰分析结果,尚未有过报道。为评估不同贮存温度和天数对野生动物粪便样品中皮质醇浓度的影响,我们将大熊猫的新鲜粪便置于3 种模拟条件(0℃ 、10℃ 和22℃ ),并进行连续6 d的检测分析。结果表明,贮存天数对粪样中皮质醇浓度有显著影响(F 5,107 = 7.501,P =...
地下鼠由于长期适应于地下洞道生活,在诸多生物学特征上都产生了一定的趋同进化现象,但目前尚未在分子水平分析其趋同进化特征。本研究利用高通量测序数据,从氨基酸位点变化和基因表达量水平,分析两种亲缘关系较远的地下鼠——高原鼢鼠和裸鼹鼠的趋同进化。氨基酸位点变化分析显示,两种地下鼠的54 个基因都存在至少一个理论趋同进化位点,其中13 个基因可以找到相对明确的表型功能注释。基因表达量分析显示,两种地下鼠在...
