Deciduous leaf fall is thought to be an adaptation that allows plants living in seasonal environments to increase photosynthetic rates during favorable periods while reducing water loss and ice damage during unfavorable periods. Observations of natural variation in deciduousness of oak leaves suggested that deciduous leaf fall may also allow plants to reduce their herbivore loads. I plan to test this hypothesis using Ceanothus velutinus, a plant that is generally evergreen but shows considerable natural variation in rates of leaf shedding during the autumn and winter. I plan to mark plants and randomly assign half of them to have their remaining leaves experimentally removed in November. I will then compare herbivore damage on individuals with and without leaves over the next season.
