Plants and insects are constantly interacting in complex ways through forest communities
since hundreds of millions of years. Those interactions are often related to variations in the
climate. Climate change, due to human activities, may have disturbed these relationships in
modern ecosystems. Fossil leaf assemblages are thus good opportunities to survey
responses of plant–insect interactions to climate variations over the time. The goal of this
study is to discuss the possible causes of the differences of plant–insect interactions' …
