动物们的“国界”问题(图)
动物 国界 野生动物
2013/8/7
国界纷争在人类社会中从来没有中断过。点击鼠标、打开电视、翻开报纸……你总能看到国家(或者地区)之间,因为领土问题而剑拔弩张地彼此演习、真枪实炮地相互厮杀。动物们也有“国界”的纷争问题。千百万年来,动物们沿袭着自己种族特有的方式,捍卫着属于自己的“疆域”……对于野生动物来说,属于自己的疆域就是一块能觅食、汲水、寻找配偶的地盘儿。它们会努力守卫这块地盘儿,当其它同类入侵时,它们会用自己的方式来警告对方...
慢肌肌钙蛋白C (Troponin C type 1,TNNC1)具有高度保守性,调控骨骼肌慢肌和心肌的收缩,影响肌蛋白的生成,从而可能导致动物肌肉的生长、进化和功能的差异。本研究以大熊猫和亚洲黑熊骨骼肌为材料,提取总RNA 和基因组DNA,运用RT-PCR 和Touch-down PCR 分别扩增出TNNC1 基因的cDNA 序列和结构基因序列,并且构建了含有TNNC1 cDNA 的重组表达载体...
以佩戴具有无线电发射功能的GPS 颈圈(Lotek GPS_ 4400M) 的放归大熊猫“祥祥”作为目标动物, 2006 年4 月至2007 年2 月,采用无线电遥测技术(RT)和GPS 跟踪技术在卧龙自然保护区的“五一棚”区域, 每日监测大熊猫在野外环境下的生存状况、移动规律和觅食行为。为了比较RT 和GPS 在高山峡谷地区空间定位的可行性和有效性,我们引入空间定位率、地形特征、空间定位差、巢域...
唐家河自然保护区毛冠鹿冬夏栖息地的比较
毛冠鹿 栖息地使用 夏季 冬季
2016/7/19
了解野生动物栖息地选择对于制定合理的物种保护和栖息地管理计划是十分必要的。2005 年12 月至2006年3 月及2006 年7 ~ 9 月,在唐家河自然保护区,我们使用样带法和粪便法调查了毛冠鹿的冬夏两季栖息地选择情况,结果表明,毛冠鹿具有季节性的在高、低坡位进行迁移的现象,冬季毛冠鹿多出现在下坡位,而夏季多出现在中坡位和上坡位。同时,我们也发现冬季毛冠鹿多在距离道路较近的地方活动,而夏季毛冠鹿...
