We Want a Shrubbery! The direct and indirect influence of Shrubs on Flowering Annual plants in an Arid Ecosystem

A progress report by Stephanie Haas

Shrubs frequently have positive interactions with annuals in desert ecosystems. This facilitative effect has been seen repeatedly with plant density, but the effect of shrubs on flowering is less studied. Shrubs also impact other species that interact with annuals, including both herbivores and pollinators. These direct and indirect interactions exist in a complex network that we attempt to tease apart through both manipulation and observation.
