在阿巴拉契亚南部3个阔叶林中，秋季腐皮虫（Alsophila pometaria, Harris）的慢性落叶导致硝酸盐氮（NO3−N）的流输出显著增加。这些综合结果清楚地表明昆虫消费者对生态系统过程具有可测量的影响，并为昆虫在景观尺度上的调节作用提供了支持。
Chronic defoliation by the fall cankerworm,Alsophila pometaria(Harris), accompanied substantial increases in the stream export of nitrate nitrogen (NO3−N) from three mixed hardwood forests in the southern Appalachians. These integrated results clearly demonstrate a measurable effect of insect consumers on ecosystem processes, and provide support for the regulatory importance of insects on a landscape scale.
