Maternal effects can induce adjustments in offspring phenotype to the
environment experienced by the mother. Of particular interest is if
mothers can program their offspring to cope best under matching
environmental conditions, but the evidence for such anticipatory maternal
effects (AME) is limited. In this study, we manipulated experimentally the
food availability experienced by mothers and their offspring in the
European earwig (Forficula auricularia). Offspring produced by females
that had access to high- or low-food quantities were cross-fostered to
foster mothers experiencing matched or mismatched environments. Offspring
experiencing food availability matching the one of their mothers had an
increased survival to adulthood compared to offspring experiencing
mismatched conditions. Females experiencing high food laid larger
clutches. This clutch-size adjustment statistically explained the matching
effect when offspring experienced high food, but not when experiencing low
food conditions. There were no effects of matching on offspring growth and
developmental rate. Overall, our study demonstrates that AME occurs in
relation to food availability enhancing offspring survival to adulthood
under matching food conditions.
