利用自由取食的合流金杨（鞘翅目：合流金杨科），我们检验了两种白杨之间自然发生的杂交带是昆虫丰度中心或“汇”的假设。在3年的时间里，我们发现94%的C合流种群被限制在13公里的杂交区，这代表了
Using the free-feeding beetle Chrysomela confluens (Coleoptera: Chrysomelidae), we examined the hypothesis that naturally occurring hybrid zones between two cottonwood species are ''sinks'' or centers of insect abundance. Over a 3-yr period, we found that 94% of the C confluens population was restricted to a 13-km hybrid zone, which represents
