Abstract

Chronic defoliation by the fall cankerworm, Alsophila pometaria (Harris), accompanied substantial increases in the stream export of nitrate nitrogen (NO-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.

摘要

由落叶松尺蠖（Alsophila pometaria (Harris)）造成的长期落叶现象，伴随着阿巴拉契亚山脉南部三个硬木混交林中硝酸盐氮（NO-N）的溪流输出量大幅增加。这些综合结果清楚地表明了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重要性提供了支持。
