贺兰山保护区岩羊(Pseudois nayaur)种群数量近年来增长很快,为了了解贺兰山保护区的岩羊种群的健康状况,从而更好的保护和管理岩羊种群,我们需要对岩羊种群的遗传多样性进行研究.我们在其近缘物种选出36对微卫星引物对收集到的岩羊粪便DNA样品进行PCR扩增.结果发现,有9对引物在岩羊粪便基因组DNA中扩增出了多态性位点.各位点基因杂合度介于0.26~0.95,平均杂合度为0.48,各位点多
2009年8月份采用静态箱法对珠江口淇澳岛湿地甲烷通量日变化进行测定,结果表明甲烷排放通量在当日23:00和翌日早晨9:00出现两个高峰值,分别为40.07mgm-2h-1和50.99mgm-2h-1;在当日17:00和翌日凌晨5:00出现两极小值,分别为1.13mg m-2h-1和1.57mg m-2h-1,同步观测孔隙水中SO42-、Cl-浓度和沉积物表层温度和采样点潮位变化,发现湿地甲烷排放
