Summary:
This study examines the demographic status of two co-occurring plant populations, Cornus florida and Lindera benzoin, with a stage matrix population projection model, and the potential for a competitive advantage in endozoochorous seed dispersal for L. benzoin in the quantity of seeds dispersed, the quality of seed dispersal, or a combination of the two. A plant pathology analysis indicates that the C. florida population has been impacted by the fungal pathogen Discula destructiva . The population model predicts a decline in the C. florida population and an increase in the L. benzoin population. Seed removal experiments revealed that significantly more seeds of L. benzoin were removed by insects, presumably ants. This could represent an important advantage for L. benzoin in the quality of seed dispersal. However, L. benzoin is likely also benefiting by the increase in colonization opportunities that are provided as individuals of C. florida succumb to D. destructiva.
