我们测试了美洲红隼（Falco sparverius）和灰尾田鼠（Microtus canicaudus）对植被高度和栖息地增加的行为和人口统计学反应。实验在16个0.2 ha的鼠笼中进行，设4个重复，每个重复分为高植被无栖木、高植被有栖木、矮植被无栖木和矮植被有栖木。1998年11月初，围栏内饲养了20只灰尾田鼠。试验第12周，在筑巢前，红隼表现出对短植被围护的偏好（P < 0.05）。在筑巢后，红隼将栖木与栖木围在一起，表现出对短植被与栖木围在一起的最大偏好。高植被围护地田鼠种群数量和招募率高于低植被围护地，但补充栖地对田鼠种群数量和招募率没有影响。在许多农业…
We tested the behavioral and demographic responses of American kestrels, Falco sparverius, and gray-tailed voles, Microtus canicaudus, to vegetation height and addition of perches. We conducted our experiment in sixteen 0.2-ha rodent enclosures with four replicates assigned to each of the following treatments: tall vegetation without perches, tall vegetation with perches, short vegetation without perches, and short vegetation with perches. The enclosures were stocked with 20 gray-tailed voles in early November 1998. Before perches were erected during the 12th week of the experiment, kestrels showed a preference for short-vegetation enclosures (P < 0.05). After perches were erected, kestrels used enclosures with perches, showing the greatest preference for short-vegetation enclosures with a perch. Vole populations and recruitment rates were higher in tall-vegetation enclosures than in short-vegetation enclosures, but supplemental perches did not affect vole populations or recruitment. In many agricultural ...
