入侵植物互花米草上的蚜虫新纪录:一条蚜及其种群分化 [PDF]
本研究报道了一条蚜Hysteroneura setariae在中国华南地区取食入侵植物互花米草,这是该植物上的首个蚜虫纪录。结合DNA条形码和系统发育分析,探究了互花米草上一条蚜种群的来源,并基于中国华南、印度、巴基斯坦、美国等地区样品的序列数据,分析了一条蚜种群遗传分化格局。结果显示:华南地区互花米草上的一条蚜来自周边其他寄主植物上一条蚜种群的扩散;北美本土一条蚜种群与亚洲地区种群具有一定程度的遗传分化。国家重点研发计划项目(2016YFE0203100);;国家自然科学基金项目(31772504);;

近年来,人类活动范围不断扩大,对雪豹(Panthera uncia)所处高海拔生态系统侵入不断增加,对雪豹生存已造成威胁。准确掌握雪豹生境选择偏好与食源结构特征,可以完善雪豹基础研究,提高雪豹保护管理效率。因此于2019年7月对卧龙自然保护区内雪豹集中分布区域进行野外调查,研究雪豹对各生境因子的选择偏好情况;分析粪便组成,明确雪豹食源结构。结果显示:雪豹偏好于海拔3500—4500 m、坡度31°—45°且地形较为崎岖的无家畜活动区域,在坡位的选择上,雪豹偏好于山脊与上坡位,避开中、下坡位与山谷 ...
