This study examines xylem functional tradeoffs with an emphasis on how storage interacts with transport and biomechanical traits. The overarching hypothesis is that the need for xylem storage has been a partial evolutionary driver of xylem structure and function among taxa in California’s biodiverse Mediterranean type climate region (MTCR). Sampled taxa include woody plants with evergreen and deciduous leaf habits, and post-fire sprouters and non-sprouters. This work Integrates teaching and research and is geared toward non-scientists and potential scientists to help understand xylem physiology of California shrubs. Dr. Brandon Pratt
