Chapter 6 (Page no: 83)

The role of vertebrates in the diversification of new world mistletoes.

Three predictions were tested to evaluate the hypothesis that vector-parasite interactions have played a role in the diversification of mistletoes. First, mistletoe taxa that are most diverse are predominantly vertebrate-dispersed. Secondly, vectors associated with mistletoes represent a narrow subset of local vertebrate assemblages. Thirdly, vector-mistletoe associations found within local assemblages are likely to reflect a long-term history of association. Observations on the number of visits and behaviour of the birds feeding on mistletoe fruits were conducted at 2 sites rich in mistletoe species, i.e. Colombia and Costa Rica. The results support the hypothesis that vector-parasite interactions have contributed to the diversification of New World mistletoes. Tabulated data on birds feeding on mistletoe fruits at 2 sites are presented, as well as on the diversity of New World mistletoes and associated dispersal modes.
