Dr. Yu-Yun Chen

My primary research interest is the mechanisms maintaining forest biodiversity and trends in a changing environment. I particularly focus on plant reproductive phenology and dynamics of early life stages. I began with long-term monitoring of flower/seed falls and seedlings in Pasoh Forest Reserve, Malaysia, and expanded my research to subtropical areas in Taiwan. With the long-term flower data, I would like to identify proximate triggers for flowering phenology in tree species and to explore possible ultimate causes of flowering patterns. In addition, through monitoring seedlings in the same forests, I would like to investigate the relationship between seeding phenology and dynamics and the impact of climate change on this relationship.
