My dissertation project uses a series of 1-ha monitoring plots on Guam and three nearby snake-free islands to determine how birds affect forest structure. This is done through an investigation of pollination, seed dispersal and herbivory in three tree species found across all islands. Several 10mx20mx10m bird exclosures will be erected on the monitoring plots in order to specifically address the mechanisms responsible for patterns found in the comparative study. By investigating the bird-plant interactions important in seed production, germination and growth of the same three plant species across several islands inside and outside of bird exclosures, I will be able to identify the role of birds in each stage of the life cycle. Then, I can predict what will happen to these plant species without the presence of birds and can compare these predictions to a natural system where birds have been lost.
