摘要：

We investigated the annual and monthly patterns of earthworm consumption by wild boar in the Maurienne valley (Alps, France). A positive correlation (R-2=0.79) was found between weather conditions and patterns of earthworm consumption. A positive correlation was also found between earthworm consumption rates and the occurence of 'worm nights', an easy and direct measure of earthworm availability.
