加州灌木丛栖息地的碎片化对三个分类群(植物、鸟类和啮齿动物)的影响是一致的。栖息地残留物内的灭绝发生得很快，根据未受干扰栖息地的种群密度，鸟类和啮齿动物物种消失的顺序是可以预测的。距离对物种多样性的影响很弱到不存在，而生境面积的影响很强。遗迹隔离后的边缘效应和累积栖息地损失与物种多样性的丧失相关。在这些分类群中很少发生重新定殖化。啮齿动物似乎极易灭绝。小而古老的斑块保留了可预测的鸟类和啮齿动物物种的子集，强化了保护区越大通常越好的原则
The effects of fragmentation in a scrub habitat in California on three taxa (plants, birds, and rodents) are concordant. Extinctions within the habitat remnants occur quickly and the sequence of species disappearances of birds and rodents is predictable based on population density in undisturbed habitat. Distance effects on species diversity are weak to non-existent, and habitat area effects are strong. Edge effects and cumulative habitat loss following isolation of the remnants are correlated with loss of species diversity. Recolonization in these taxa occurs rarely. Rodents appear to be extremely susceptible to extinction. Small, old patches retain a predictable subset of bird and rodent species, reinforcing the principle that larger reserves are generally superior
