Evolutionary patterns and processes of epiphytism in vascular plants.

Vascular plants include 350,000 or more species and play critical roles in Earth's terrestial ecosystems. Much of this diversity consists of epiphytic species specialized to grow on the surfaces of other plants (notably tree canopies). Vascular epiphytes are ecologically important, especially in the tropics, and comprise about 10% of global vascular plant diversity. In many cases, epiphytism is phylogenetically conserved, with several large clades making up the great majority of vascular epiphyte diversity. However, epiphytes may be characterized by a diversity of ecological strategies, and epiphytism itself has evolved independently in many lineages. The processes that underlie the evolution of epiphytism in vascular plants, however, are not well understood. Here we more thoroughly characterize the phylogenetic patterns of epiphytism in vascular plants using a nearly complete generic-level phylogeny (containing about 90% of vascular plant genera), and test a variety of hypotheses regarding underlying evolutionary processes.
