| 摘 要： | 采用无线电跟踪观察和固定样地调查的方法,研究了凉水国家级自然保护区松鼠冬季重取生境特征。结果表明:松鼠的重取区集中在巢树附近40~60 m内的林隙中,重取区的乔木以针叶树为主,地面被覆苔藓及阔叶树落叶。重取区的冠层郁闭度和灌木密度均低于对照样地。重取生境的特征表明,空间记忆和视觉刺激是松鼠重取的可能机制。

| Abstract: | Radio-tracking technology and fixed area plot sampling method were used to investigate habitat characteristics of retrieved-cache areas for Eurasian red squirrels in Liangshui National Nature Reserve,Heilongjiang Province in winter.Results show that the retrieved-cache areas for Eurasian red squirrels are in forest gaps 40~60 meters away from nest trees.Conifers are dominant in the retrieved-cache areas,and moss and broad-leaved trees are the main ground covers.Forest canopy closure and shrub density in the... |
