关于幼狮（Felis concolor）扩散的时空格局的信息很少，也没有关于栖息地走廊扩散器使用的数据。我调查了无线电标记幼狮（8米，1英尺）在加利福尼亚景观中的分布情况，该景观包含3条走廊（1.5公里，4.0公里和6.0公里长）和几个由城市发展产生的栖息地半岛。分散通常是由母熊在其活动范围的边缘抛弃幼崽开始的。幼崽在距离该地点300米的地方停留了13-19天，然后向母熊的相反方向分散。分散时的平均年龄为18个月（13-21个月）。每个分散者都从其出生的范围移动到城市-荒野边缘的最远部分。分散的雄性占据了一系列的小(
There is little information on the spatiotemporal pattern of dispersal of juvenile cougars (Felis concolor) and no data on disperser use of habitat corridors. I investigated dispersal of radio-tagged juvenile cougars (8 M, 1 F) in a California landscape containing 3 corridors (1.5, 4.0, and 6.0 km long) and several habitat peninsulas created by urban growth. Dispersal was usually initiated by the mother abandoning the cub near an edge of her home range. The cub stayed within 300 m of that site for 13-19 days and then dispersed in the direction opposite that taken by the mother. Mean age at dispersal was 18 months (range 13-21 months). Each disperser traveled from its natal range to the farthest part of the urban-wildland edge. Dispersing males occupied a series of small (
