    Optimal defence theory predicts investment in extrafloral nectar resources in an ant-plant mutualism

    Export to Mendeley

    Here, we employ optimal defense theory for plant secondary compounds, to evaluate plant production of extrafloral nectar resources to attract & reward ants for resistance against herbivores. Through ant exclusion & artificial herbivory experiments, we examined investment in extrafloral nectar by both buds & fruits of Pachycereus schottii, senita cacti, in the Sonoran Desert of North America. Indirect defence through extrafloral nectar production is in accord with direct defence through plant secondary compounds. This supports the optimal defence theory as a general framework with which to evaluate the costs of producing resources (i.e. for the defense) by plants, lycaenids, & homopterans to attract & reward ants for their resistance against natural enemies in protection mutualisms.

    Description

    Title : Optimal defence theory predicts investment in extrafloral nectar resources in an ant-plant mutualism
    Author(s) : J. Nathaniel Holland, Scott A. Chamberlain, Katherine C. Horn
    Abstract : Here, we employ optimal defense theory for plant secondary compounds, to evaluate plant production of extrafloral nectar resources to attract & reward ants for resistance against herbivores. Through ant exclusion & artificial herbivory experiments, we examined investment in extrafloral nectar by both buds & fruits of Pachycereus schottii, senita cacti, in the Sonoran Desert of North America. Indirect defence through extrafloral nectar production is in accord with direct defence through plant secondary compounds. This supports the optimal defence theory as a general framework with which to evaluate the costs of producing resources (i.e. for the defense) by plants, lycaenids, & homopterans to attract & reward ants for their resistance against natural enemies in protection mutualisms.
